CCTV News:Gao Fenglin, male, born in March 1962, Han nationality, party member of the Communist Party of China, is a special fusion welder and senior technician of Capital Aerospace Machinery Co., Ltd., the First Research Institute of China Aerospace Science and Technology Corporation.

　　Gao Fenglin has participated in a series of major aerospace projects, and the welded rocket engines account for nearly 40% of the total number of rocket engines. It has overcome the technical problems of Long March 5, and made outstanding contributions to the smooth implementation of national key projects such as Beidou navigation, Chang ‘e lunar exploration, manned space flight and the development of the new generation launch vehicle of Long March 5.

　　Honors won: second prize of national scientific and technological progress, national model worker, national May 1st Labor Medal, national moral model and most beautiful worker.

　　Gao Fenglin, male, born in 1962, Han nationality, party member of the Communist Party of China, is a special fusion welder and senior technician of Capital Aerospace Machinery Co., Ltd., the First Research Institute of China Aerospace Science and Technology Corporation. In his hands, the welding torch is a needle, and the arc light is a line. He pursues the welding light and welds a sky on the "golden thread" of the rocket engine. He is the special fusion welder of Capital Aerospace Machinery Co., Ltd., the First Research Institute of China Aerospace Science and Technology Corporation, the team leader of the rocket engine welding workshop, and the national senior technician — — Gao Fenglin.

　　It is said that Gao Fenglin is a "golden hand welding", not only because early people called the welder trained by argon gas, which is more expensive than gold, "golden hand"; It is also because the object he is welding is very expensive, and it is an engine known as the "heart" of the rocket; But also because he has reached a height that ordinary people can’t reach in the field of rocket engine welding. "Golden Hand and Sky Welding" is a portrayal of Gao Fenglin’s superb skills and repeated difficulties in welding technology, and it is also the embodiment of the elegant demeanor of high-skilled aerospace workers in the new era.

　　First, I am determined to serve the country and practice welding skills in the aerospace industry.

　　Gao Fenglin, who just stepped out of school, entered the argon arc welding group of the rocket engine welding workshop with abundant talents, and studied skills with the first generation of argon arc welders in China. In order to practice basic skills, he used to use chopsticks to gesture welding and wire feeding when eating, used to hold a jar full of water to practice stability when drinking water, held an iron block to practice endurance when resting, and even braved the high temperature to observe the flow law of molten iron. Gradually, Gao Fenglin’s accumulated energy generate came out.

　　In the 1990s, the welding of the large nozzle of a new type of high thrust hydrogen-oxygen engine designed for China’s main rocket Changsanjia series launch vehicles once became a bottleneck in development. The length of all welds is nearly 900 meters, and the pipe wall is thinner than a piece of paper. If the welding torch stays for 0.1 second, the pipe may burn through or leak. Once burn through and leak occur, not only the large nozzle will be scrapped, but also the development progress and launch date of the rocket will be affected. Through continuous exploration, Gao Fenglin and his colleagues overcame two major difficulties, namely burning through and welding leakage, with superb skills. However, the X-ray inspection of the first welded large nozzle shows that there are more than 200 cracks in the weld, and the large nozzle will be sentenced to death. Undaunted, Gao Fenglin made an analysis and investigation from the aspects of material performance and structural characteristics of large nozzle. In the end, at the high-level technical analysis meeting, he boldly said in the questioning voice of many technical experts that it was a fake crack! After the cutting test, it is shown that his judgment is correct under the microscope of 200 times. In this regard, the first large nozzle was successfully sent to the test bench, and the successful application of this new type of large thrust engine greatly improved the carrying capacity of our rocket.

　　With more and more urgent and difficult jobs, Gao Fenglin has shouldered more and more burdens. In the welding research of a certain type of ejector, he made bold improvements, which solved the unsolved problems in the past year and a half and ensured the delivery of products with an output value of nearly 100 million. The launch system of a national submarine-based key model is in trouble near the critical moment of launch. Under the direct instruction of the model chief engineer, Gao Fenglin studied and adopted special techniques, and eliminated the fault overnight, thus ensuring the launch of this product as scheduled.

　　Second, the courage to innovate, self-breakthrough achievement expert workers

　　Gao Fenglin dared to try in his work, persisted in innovation and breakthrough, and turned countless "impossible" into "possible". The qualified rate of a certain engine component is only 35%. It takes half a year for the model to produce a large number of qualified products. This product is processed by soldering, while Gao Fenglin’s major is fusion welding, which is a cross-disciplinary research. Gao Fenglin understood the mechanism from the theoretical level and grasped the key from the technical level. He ran to the library, browsed professional and technical websites, and tried his best to search for relevant information at home and abroad. Every day, Gao Fenglin led the team members to conduct experiments in an operation room of more than 20 square meters, and conducted hundreds of experiments in two months, clarifying the genetic mechanism of the two materials, and repeatedly improving them from the aspects of environment, temperature and operation control. The final processing technology made the qualified rate of the product reach 90%.

　　The continuous success did not make Gao Fenglin feel high. Instead, he felt the value of knowledge more and more, and thought that operators should arm their minds with wisdom to better guide the practical operation. After leaving school for 8 years, Gao Fenglin re-entered the campus, picked up his textbooks and began his hard spare-time study for 4 years. During the day, he shuttled to the work site, training ground and classroom, and at night, he studied with two thick stacks of books until 3 or 4 o’clock. Due to excessive tension and fatigue, his hair fell off in handfuls when he was less than 30 years old. Everything comes to him who waits. Gao Fenglin first achieved good results in practice and theory in the technical competition, and soon got a college diploma that he had been looking forward to for many years. After that, he completed his study from undergraduate to graduate.

　　Not only can you do it, but you can also write it to guide others to do it. Gao Fenglin has been asking herself this way. In the butt welding of engine nozzle, which is very difficult to operate, Gao Fenglin studied the characteristics of the product and applied what he learned flexibly, and put forward the "anti-deformation compensation method" to control the deformation. Later, this process won the second prize of national scientific and technological progress; He also edited the first model engine welding technical operation manual and other industry specifications, and was appointed to participate in the formulation of relevant aerospace standards for many times. Through the process of self-study, practice, summary and re-practice, Gao Fenglin has gradually become an authoritative welding expert in China and an expert worker who combines profound theory with exquisite skills in everyone’s eyes.

　　In 2006, the antimatter detector project involving 16 countries and regions in the world was in trouble because of the manufacturing problem of low temperature superconducting magnets. The proposals put forward by two groups of international and domestic technical experts failed to pass the review of the international alliance led by the National Aeronautics and Space Administration (NASA). At a loss, Professor Ding Zhaozhong, a Nobel Prize winner, inquired about Gao Fenglin and asked him to help. Gao Fenglin went to the site to conduct basic research and textual research. He pointed out: according to the traditional control method, the previous two schemes are impeccable, but there are great hidden dangers for this special structure. He stated his design scheme, which was finally recognized by NASA and the League of Nations. An expert commented on Gao Fenglin: "You have both profound theory and rich practical experience. You look at the problem from two dimensions. It seems that highly skilled talents are of great use!"

　　Third, be willing to give, and work hard to witness the ordinary greatness.

　　The particularity and risk of aerospace products determine that many problems must be solved under very difficult and dangerous conditions. Gao Fenglin is willing to devote himself to the front line of welding, working hard, facing up to difficulties at the most needed moment, and has made extraordinary achievements in his "ordinary" post.

　　In order to meet the launch of large-capacity and large-tonnage satellites, China has built the largest full-arrow vibration test tower in Asia, in which the welding of the vibration girder is the key, which belongs to the first-class weld, and the material used to make the vibration girder is very special and the welding is very difficult. In order to meet the welding requirements of vibrating girder, Gao Fenglin should operate continuously at high temperature. The surface temperature of the weldment reached several hundred degrees, and Gao Fenglin’s hands were baked dry, and a series of blisters were bulging. In order to finish the task on time and with good quality, he gritted his teeth and finally welded a qualified vibration beam. During the later manned spaceflight project, the vibrating girder was upgraded and tested. The results show that the welding quality of the girder is good, and the bearing capacity can be increased from 360 tons to 420 tons, which can continue to serve for the development of launch vehicles in China. The vibrating girder has stood the test of time, and Gao Fenglin’s hands are still scarred by severe burns.

　　During the development and production of Long March 5, the engine suddenly leaked from the inner wall during the launch pad test. Standing on the test bench facing the product, behind him is a mountain stream of tens of meters, and Gao Fenglin is fearless in times of crisis. Because of the special environment, the fault point can’t be observed, and the operating space is very narrow, Gao Fenglin managed to finish the "emergency rescue" by using superb skills and special techniques under the condition that he could barely fit into one arm.

　　Gao Fenglin has been rooted in the front line of aerospace and engaged in the welding of rocket engines. He has overcome more than 200 difficulties in major research projects of aerospace product engine models. He has also actively contributed his talents to fill technical gaps in titanium alloy bicycles, large vacuum furnaces, ultra-thin large bellows and other fields, creating value for the national economy. Foreign-funded enterprises have been hired with high salary and housing, and he is unmoved; Many times can be promoted, Gao Fenglin also gave up. He always believed that his roots were in the welding post.

　　Fourth, willing to educate people, preaching and teaching paved the way for peaches and plums.

　　It is not spring to outshine others. Apart from being a master of skills, Gao Fenglin also has a significant job, which is to continuously train more outstanding aerospace high-skilled talents like him.

　　In terms of technology inheritance, Gao Fenglin unreservedly passed on his accumulated rich experience to young people. He groped and summed up a set of methods for talent training and management. His advocacy of "mentoring by teachers" and "One Belt and One Belt" and his creation of "welding" education method have been widely recognized and applied in practice. It has cultivated five national technical experts and one central enterprise technical expert. He was invited by the Central Organization Department and Publicity Department of the Communist Party of China to have an exchange of "artisan spirit", participated in the "activities of artisans from big countries entering the campus" and "exhibition of innovative achievements of workers on both sides of the Taiwan Strait" of the All-China Federation of Trade Unions, and actively promoted the spirit of model workers, labor spirit and craftsman spirit.

　　In 2005, Gao Fenglin’s team was jointly named "Gao Fenglin Team" by China National Defense Posts and Telecommunications Union and Aerospace Science and Technology Corporation, becoming the first team named after a model worker in the First Aerospace Institute. As a demonstration base for team building, Gao Fenglin team has fully played a typical demonstration and radiation-driven role in producing models, achievements, talents and experiences. Teams and teams have teamed up with more than 30 teams inside and outside the space system to carry out various exchanges and cooperation. Through technical cooperation, more than 20 major scientific research topics such as aerospace engine welding and development have been solved. Received many training courses for national excellent team leaders of the Ministry of Human Resources and Social Security, as well as visits and exchanges from nearly 200 brother units such as China Commercial Aircraft, China Electric Power Branch and Shougang Group. Under the leadership of Gao Fenglin, the team has successively won many honorary titles such as "National Worker Pioneer", National Learning Excellent Team, National Safety Production Demonstration Team and Central State-owned Enterprise Learning Red Flag Team "Benchmark" with its impressive performance. In 2011, Ministry of Human Resources and Social Security awarded Team Gao Fenglin as a national skill master studio. In 2017, the All-China Federation of Trade Unions awarded Gao Fenglin Team as a national model model worker and craftsman talent innovation studio.

Using crawler technology to analyze the word frequency of the retrieved information, find the perspective of concern from high-frequency words, and tap the context of national policy changes, and the results are quantifiable.

Fourth, the actual operation

The practical application of the above theory takes the report about Beidou Industrial Park made by Dai Chunchen as an example. The report attracted the attention of senior leaders at that time, and promoted the implementation and changes of relevant industrial policies.

Writing process:

1. Determine the topic and find the value

News from the beginning: Xinhua News Agency mentioned that Beidou satellite system won the highest scientific and technological progress award; And the award was awarded to the team, which was the first national highest scientific and technological progress award won by the team.

Discover the value point: According to the interview, there are no enterprises in some Beidou navigation industrial parks and they are vacant.

2. Establish knowledge reserves and build an article framework.

Use different search channels to establish knowledge reserves, determine the general direction through relevant seminars and forum information, and read papers in China HowNet to establish a systematic understanding of the industry and find the conflict point.

3. Find supporting materials and interviewees, and use interviews to support reports.

4. Search and verify information and cross-correlation.

(1) search local government related planning found suspicious.

/Original content/

The interesting detail is that a province in central China has issued a Beidou industrial plan, and three Beidou industrial parks have been set aside in one breath, requiring the three industrial parks to cultivate and introduce more than 500 Beidou enterprises by 2018, with a total industrial scale of more than 60 billion yuan. Another central province put forward the "Thirteenth Five-Year Plan" goal of Beidou application market with a scale of 100 billion yuan.

This is an extremely ambitious goal. Even in the National Medium and Long-term Development Plan for Satellite Navigation Industry, the scale of the national satellite navigation industry in 2020 is only 400 billion yuan. According to the proportion of 60% and 80% of Beidou system in different fields, the final scale of Beidou industry is only 240-320 billion yuan. The indicators of these two provinces have reached more than half of the above data.

Under the background of planning and setting targets in various places, cities and industrial parks compete fiercely for Beidou enterprises and Beidou talents, and the results can be imagined. According to industry insiders, some Beidou industrial parks are actually vacant in different degrees. The first problem they face is that they can’t recruit Beidou projects, and the second is that the recruited projects are "fake Beidou". Such a departure from the original intention of the establishment of the park can be imagined as a waste of government financial resources and land resources.

② Replace the interviewee’s personal subjective viewpoint with the retrieved information: it not only protects the offline interviewee, but also makes the information point more convincing.

/Original content/

As early as 2014, Yang Yuanxi, an academician of the Chinese Academy of Sciences, who took the lead in formulating the National Medium-and Long-term Development Plan for Satellite Navigation Industry, also shouted that he couldn’t understand the situation of Beidou Industrial Park in various places. According to media reports, during the National "Two Sessions" that year, Yang Yuanxi, a member of Chinese People’s Political Consultative Conference, said vehemently that the Beidou Industrial Park in China was blooming everywhere, and each park occupied thousands of acres of land. Many provinces and cities use the signboard of Beidou Industrial Park to enclose land everywhere, and many enterprises are applying for projects and funds from the government in the name of Beidou Navigation.

Yang Yuanxi’s explanation for the root cause of this chaos is the excessive supply of venues. In his view, Beidou industry is a high-tech industry, and there is not much land needed. At present, the domestic Beidou market cannot support the survival of so many Beidou enterprises. This is also the view of many people in the industry.

③ Make logical deduction in the search results, provide exclusive information and unique perspective, and ultimately affect policy decisions.

/Original content/

In China’s blossoming industrial parks, foreign capital, foreign advanced technology and management experience are introduced, which is nothing more than the migration of industries, from 1 to 100. Under this logic, the park provides tax incentives, low-priced land, and facilitates the recruitment of cheap labor. The formation of an industrial chain in the park also enables manufacturing enterprises to save costs.

However, if Beidou Industrial Park is established, most of the imported enterprises are not formed technology and management experience. Most Beidou project teams may have scientific research achievements and intellectual property rights, but how to industrialize and adapt to the market, they still need to explore while doing, and they need to complete the creation of "from 0 to 1".

Fundamentally speaking, they are makers, and Beidou industry is an innovative economy that needs incubation and growth. The growth environment needed by the innovation economy should be closer to the Silicon Valley in the United States-the high concentration of scientific research resources, the concentration of high-quality talents and specialized venture capital. This is quite different from the "three axes" of local governments to develop traditional manufacturing industries.

　　This round of oil price increase can really be described as "meat pain". Compared with the previous small fights, this round of price increases has indeed interpreted a "wolf coming". The fluctuation of oil price can’t be controlled, but the level of fuel consumption can be controlled. Driving skills and traffic congestion are very important. But more importantly, I think from the technical level, not to lose power and driving sense, but also to have lower fuel consumption, hybrid technology immediately entered the alternative list. In the context that oil prices are likely to continue to climb, have you begun to pay attention to hybrid models?

　　First, Toyota Saina

　　Model guide price: 309,800-405,800 yuan

　　Highlights of the model: synchronization with overseas, 2.5L dual-engine power.

　　Since hybrid technology has attracted attention, Toyota can be said to have dominated for a long time. Whether in domestic or international markets, the performance is quite eye-catching. Today, the Toyota family has brought the latest dual-engine power. All its main models are equipped, so let’s take a look at the very topical Toyota Saina today.

　　Saina, of course, was born on the brand-new Toyota TNGA-K platform, and is the same as the fourth-generation Toyota Highlander. We have deeply understood the product advantages brought by the brand-new platform from Asian Dragon, new RAV4 and other models. Among them, the biggest feature is the hybrid power system composed of 2.5-liter naturally aspirated engine and motor. In the same class, this power combination has distinctive characteristics, ride comfort and fuel consumption are also very close to the people, which can be said to be one of the biggest highlights of Saina.

　　In terms of appearance, Toyota Saina has almost maintained the same shape as overseas models, and basically achieved the original flavor. While leaning towards home style, it highlights a little business atmosphere. The front of the car looks round, with rich shapes and levels. The slender headlights play a role in segmentation, but also make the front face look less bloated. The exaggerated net shape at the bottom also looks like it is eyeing.

　　The body size of Saina is maintained at the mainstream level, 5165/1995/1765mm, and the wheelbase is 3060 mm. The biggest feature of the car side is the use of the waistline of the car body, which has a strong three-dimensional effect and makes the car body appear thicker. The rear of the car is also stocky and there is no lack of design, and the extension and shape of the taillights are very three-dimensional, which echoes the headlights. On the whole, the design of Saina can still meet the tastes of most consumers, and there is not much controversy.

　　However, in the interior part, Toyota’s performance is a bit enterprising, and it is also the most unsatisfactory point, especially when it is not refined enough in the localization transformation. The central control screen as thick as a brick on RAV4 and Willanda and the car system with monotonous color and lack of experience have already disappointed consumers. However, the experience and operation of this set of car machines in Saina can only be said that the progress is limited, and there are changes. Except for the larger size, it can’t be compared with the current mainstream brands or even independent brands. In contrast, GL8 is the best example. Pan-Asia has laid a strong local flavor of China for GL8, while retaining the necessary American luxury. Toyota should not fail to understand the truth that there is a car in front and a road behind.

　　Saina’s use of space is also very extreme. Three rows of seats are necessary, and the second row has no problems in front and back adjustment, function and comfort. The actual experience of the third row of seats depends on the size of the occupant. If it is too big and strong, it is recommended to use it only for short-distance emergency.

　　The trunk of the Saina has formed a deep pit structure, which is completely inherited from the design style of North America. Don’t underestimate this design. During the actual experience, it is found that its volume can be stuffed into an adult, and it can be accommodated when the third row is not used. Therefore, the ingenious design is the core for a car like Saina.

　　In terms of power, Saina is equipped with Toyota’s 2.5L twin-engine hybrid. Matching E-CVT gearbox, as mentioned above, fuel saving and smoothness are still its most prominent features. Among them, the 2.5L engine has a maximum power of 141kW and a maximum torque of 238N.m；: The maximum power of the motor is 134kW and the maximum torque is 270N.m In the actual experience, it can achieve the fuel consumption performance between 6.0 and 70L, which is still good.

　　Comments: At present, the sales volume of Saina is on the rise, and the price increase that had been raging before seems not to have completely disappeared. Anyone who can buy this car at a higher price is probably true love powder, or that sentence, just like it.

　　Second, Honda Odyssey sharp and mixed

　　Model guide price: RMB 235,800-354,800.

　　Highlights of the model: the design of the small change is more reasonable and easy to operate. Sharp and hybrid bring better driving experience.

　　Odyssey can be said to be an evergreen tree in the home MPV market, and the overall design idea is also different from other models. First of all, the overall body lines are relatively round, and the more compact size can bring more flexible handling performance. Unlike the bloated body like Senna and GL8, it is more calm and calm when the car meets and the parking space is tight. If the hostess at home often drives MPV, she should prefer Odyssey, and I will push it first.

　　In terms of interior design, Odyssey is also more inclined to home, and the home style is very strong. After a small change, the classic key shift mechanism is used to save a lot of operating space. Give consideration to design and aesthetic feeling. After the change, the size of the central control panel has changed, and the color has become richer and more delicate. At the same time, the air conditioning control area below has been redesigned and operated by touch, which has obviously improved both in style and function. On the whole, I feel that the taste of home is very strong, lacking a little business breath, which is especially suitable for family use. Another storage slot is added to the glove box of the front passenger, which is ingenious in design. At the same time, the central control area is covered with soft materials in a large area, which makes the sense of grade and touch more pleasing.

　　The seat of Odyssey is actually elegant. The first feature is that it is very thick, which fully explains the basic characteristics that an MPV model should have. Besides comfort, flexibility is another major feature. The shoulders of the second row of seats can be adjusted independently, and they can also move left and right. The third row of seats can also be magically "backflips", which is particularly suitable for fishing scenes. These are the features that other models don’t have. At the same time, Odyssey has also launched a well-being car to facilitate people with disabilities to get on and off, and it is commendable to consider it more carefully and comprehensively.

　　The sliding door is also the soul of an MPV model. Odyssey uses electric+gesture control operation, which has a high recognition rate and is more convenient to operate.

　　At the configuration level, the Odyssey has been upgraded after a small change to provide 18-inch wheels, electric trunk, lumbar support, ventilation of the second row of seats, heating, massage, LED far and near lights and so on. At the same time, it has a relatively complete driving assistance system (lane departure warning/maintenance assistance, active safety system, full-speed adaptive cruise), and provides front airbags, front side airbags, head airbags and other configurations. In addition, it is equipped with panoramic images, bilateral electric side-sliding doors, automatic headlights, automatic folding of exterior mirrors, and multi-zone automatic air conditioning. In terms of intelligent configuration, this time, a 7-inch LCD instrument+a 10.1-inch floating central control panel is added, and the latest Honda CONNECT 3.0 intelligent guidance interconnection system is embedded under the screen, which can realize mainstream functions such as voice recognition, remote control, car networking and OTA upgrade.

　　In terms of power, the Odyssey is equipped with Honda’s third-generation i-MMD hybrid system, and uses a powertrain consisting of a 2.0L self-priming engine and a motor. The comprehensive maximum power is 215 horsepower, which satisfies most of the use scenarios. The initial acceleration of the motor and the application of the E-CVT gearbox make the Odyssey very smooth to drive, and there is no feeling of frustration.

　　Comments: Odyssey is more inclined to family use scenarios. After a small change, the configuration has been improved, and the consideration is more thoughtful. However, the space is short-board, and the ultimate utilization rate and loading capacity are not as good as those of GL8 and other models.

　　Third, Mocha DHT-PHEV

　　Model guide price: 295,000-315,000 yuan

　　Highlights of the model: the self-developed hybrid system makes the motor more powerful and advanced.

　　There is nothing we can do about the rapid rise of oil prices, but the iteration and progress of technology are also rapid. More crucially, these core technologies have begun to be gradually mastered in independent brands. Great Wall Motor, which has a huge consumer group, has introduced a variety of hybrid models to consumers, among which Moka DHT-PHEV is undoubtedly a very important product in the family. Not long ago, Moka DHT-PHEV officially announced its price. Among the many highlights, I believe that most consumers pay more attention to its hybrid technology. Many media have tested a circle on the Seventh Ring Road in Beijing before, with only one purpose, that is, a box of oil challenges 1000km.

　　Different people have different views on style and modeling, so I won’t describe it too much here. From the overall modeling point of view, Moka DHT-PHEV continues the family design, and the most striking thing is the huge hexagonal net. Together with WEY’s LOGO, the overall recognition is very high. The rectangular headlights on both sides and the vertical decorations on both sides of the bumper make this Mocha DHT-PHEV look fuller and more angular.

　　The side of the car is still treated with a high waistline, and the popular hidden door handle is also used, with 21-inch highlighted black wheels, which highlights a certain sports model. The design of the rear of the car is highly consistent with the front of the car, and the taillight style and bottom decoration are almost the same. But it lacks some innovative elements. In terms of body size, the length, width and height of Moka DHT-PHEV are 4875/1960/1690mm and the wheelbase is 2915mm, respectively.

　　The interior design is also consistent with the traditional fuel version, equipped with a 14.6-inch floating central control panel to increase the size of the AR-HUD head-up display, as well as a voice recognition system and AI intelligent facial recognition. Mocha DHT-PHEV has five millimeter-wave radar probes and a forward-looking camera, which are used to provide hardware support for L2 autonomous driving. I just hope that there will be no other twists and turns in the Qualcomm high-performance chip.

　　Another key feature of Moka DHT-PHEV is its intelligence, and it also supports NOH intelligent pilot-assisted driving system. It can automatically drive and command vehicles to go up and down the ramp on high-speed and urban expressways, follow the navigation route automatically all the way, and intelligently control the speed and distance of the preceding vehicle according to the road speed limit and road shape.

　　Finally, talk about power. The Great Wall lemon hybrid DHT system is a hybrid system developed by the Great Wall for three years. At present, the HEV/PHEV hybrid system has been fully installed on the main models of the Great Wall, while the Moka DHT-PHEV is equipped with a 1.5T engine and motor combination, with the maximum power of the engine being 115kW (156HP) and the maximum power of the front/rear drive motor being 135kW. The ternary lithium battery pack with a capacity of 39.67kWh is used, and the pure electric cruising range is 204km under WLTC conditions.

　　At present, many consumers pay attention to PHEV models in two aspects: pure battery life and feed fuel consumption. High pure battery life can prevent car owners from looking for charging piles frequently in order to ensure a better fuel-saving experience, while feed fuel consumption can better reflect the consistency of vehicles and whether the technology is mature and reliable. Avoid embarrassing things, and be consistent with electricity and electricity. After testing, the two-wheel drive long-life version of Moka DHT-PHEV can achieve WLTC fuel consumption of 5.5L； per 100 kilometers; The high-performance electric four-wheel drive model can achieve WLTC’s fuel consumption of 6.3L per 100 kilometers. The performance is still good.

　　Comments: The overall feeling of Moka DHT-PHEV is very clear and familiar. The driving style is similar to the previous fuel version, but it is undoubtedly more fuel efficient.

　　Fourth, Geely Xingyue L Raytheon Hi-X hybrid version

　　Model price: none

　　Highlights of the model: the technical upgrade of star products, the world’s first hybrid model equipped with a 3-speed electric drive transmission DHT Pro.

　　In the self-owned brand SUV in 2021, Geely Xingyue L is definitely a very eye-catching one, which makes people look at it with its strong product strength. However, Geely obviously does not want to stop at the level of traditional fuel vehicles, and the arrival of hybrid systems is also a matter of course. Still at the Guangzhou Auto Show in 2021, we saw the official release of Geely Xingyue L Raytheon Hi·X hybrid version.

　　Geely Xingyue L Raytheon Hi·X hybrid version basically follows the outline of the gasoline version in appearance, but it is bolder in the adjustment and depiction of details, which has a sci-fi color and a strong tram style. The most significant change in the front face comes from the middle net area, adding a number of self-luminous parts, including the LOGO and the luminous design on both sides, which are very clear and easy to identify even during the day. The grille style built in China Net has also changed the arrangement style, and the hybrid model is more gas-filled than the gasoline version. The second is the style of the bottom bumper, which has also been designed into a very representative "X" shape. Once again, it enriches the sci-fi color attributes of vehicles. In other body details, the hybrid version of Raytheon Hi·X has not changed much.

　　In terms of power, the new car is equipped with a DHE15 hybrid engine, with a thermal efficiency of 43.32% and a high-efficiency area coverage rate of nearly 50%. Xingyue L Raytheon Hi·X hybrid version is equipped with a hybrid power system consisting of a 1.5T three-cylinder engine, with a maximum power of 110kW(150 HP) and a peak torque of 225Nm. With the dual-motor system, the combined maximum power of the power system is 180kW(245 HP), matching the DHT Pro 3-speed hybrid electric drive gearbox, and the NEDC cruising range is nearly 1300km.

　　The most striking thing is that Xingyue L Raytheon Hi·X hybrid version is the world’s first hybrid product equipped with a 3-speed electric drive transmission DHT Pro. According to official data, the car’s acceleration time is 7.9s, and the longest cruising range with full oil reaches 1300 kilometers.

　　The 3-speed electric drive transmission DHT Pro will not be described in detail here. Simply put, it is no longer a gearbox in the traditional sense, but also can independently participate in the electric drive device, which is also the intelligent energy control center of the whole hybrid system. At the same time, intelligence is another major feature. The 3-speed electric drive transmission DHT Pro in the car is also fully integrated with the intelligent electronic and electrical architecture GEEA 2.0, so that the system can identify the driver’s driving habits and road congestion, and realize the adaptive, autonomous learning and adjustment of driving mode.

　　Comments: Xingyue L Raytheon Hi·X, like other hybrid models, is efficient, energy-saving and pays attention to intelligent expansion, and it also has the advantage of interior space, which is also very important.

　　Fuel-saving, long battery life, more intelligent, but also have a rich driving experience. This is the new expectation that consumers put forward for hybrid models at present. It seems a bit harsh, but don’t worry, the above is no longer unattainable today. If you haven’t done it yet, it means that you are out of date.

　　Recently, a number of international investment institutions, including Morgan Stanley and Goldman Sachs, have been "singing more" on the China stock market, and many institutions have even taken out "real money and silver" to buy more China assets.

　　Experts said that with the implementation of a series of steady growth measures in China and the accelerated optimization of epidemic prevention and control measures, the expectation of China’s economic stabilization and rebound has become clearer, attracting international institutions to re-examine the allocation value of China’s assets. In the future, under the background of China’s deepening the high-level institutional opening-up of the capital market, the efforts of international institutions to "buy in buy buy" are worth looking forward to.

　　Institutional upward adjustment expectations

　　Recently, a number of overseas investment institutions have increased their allocation to the China stock market.

　　On December 4th, Morgan Stanley upgraded the China stock market from "standard" to "over-allocation", and it is predicted that the MSCI China Index will rise by 14% by the end of 2023. Wang Ying, chief equity strategist of Morgan Stanley China, said that the evaluation framework shows that the prevention and control measures of China epidemic are continuously optimized, the real estate market is stabilized, and the regulatory adjustment is in the final stage, so the stock risk premium may be improved, so the target price for the entire China market is raised, and there is a greater chance of revaluation by 2023.

　　Coincidentally, on November 30, Goldman Sachs also said that it would also give a proposal of "high allocation" for A-share investment in 2023, and it is expected that the valuation of A-shares will rebound significantly. Liu Jinjin, chief China equity strategist of Goldman Sachs, said that under the expectation that the macro-control is intensified and the GDP growth rate is expected to pick up, we are optimistic about the performance of China stocks listed at home and abroad.

　　Bank of America’s strategy team believes that China’s domestic stocks are bound to rise due to the excess savings of China residents and the continuous optimization of epidemic prevention policies. Rui Dalio, the founder of Bridgewater, believes that some valuable assets can be found in the China market at present. China is the second largest economy in the world, and investors can improve their diversification by investing in China.

　　The support of international institutions is not groundless. Recently, the overseas listed China ETF, China Stock Exchange and offshore RMB exchange rate all ushered in a wave of solid rise, which enhanced the confidence of foreign institutions to invest in China. For example, since November, the net value of iShares MSCI China ETF with a scale of over $7 billion has increased by over 30%; NASDAQ Jinlong China Index rose by more than 40% in November, the largest monthly increase since records began in 2003. The RMB exchange rate has also recently gone out of a strong upward trend. On the morning of December 5, the offshore RMB exchange rate against the US dollar rose to 6.9813, the highest since mid-September.

　　"At present, some major economies continue to tighten monetary policy, the risk of economic recession has intensified, and market return expectations have weakened. In contrast, China has a stable economic development and clear investment logic. " Li Zhan, chief economist of China Merchants Fund Research Department, analyzed that China’s economy is changing from high-speed growth to high-quality development, and there are a lot of investment opportunities in the process of industrial upgrading and consumption upgrading in various industries. At the same time, China recovered quickly from the impact of the epidemic, and its economy rebounded significantly in the third quarter, and its position in the global industrial chain was rising day by day. In addition, China’s financial opening to the outside world has been continuously promoted, and the channels for foreign investors to participate in the domestic financial market have been continuously optimized, attracting the attention of more and more international investors.

　　The attractiveness of A shares has increased.

　　In addition to high-profile "singing more" China assets, foreign investors also took out "real money and silver" and continued to substantially increase their positions in A shares. As of December 6, the net purchase of northbound funds in 30 days exceeded 75 billion yuan, and the net purchase in the past 10 days reached 42.8 billion yuan.

　　Looking forward to 2023, the market expects that the pace of foreign investment "buying in buy buy" will continue to accelerate. "In 2022, nearly 70% of the financing amount in the A-share market comes from science and technology innovation board and the Growth Enterprise Market, which fully reflects the support of the capital market for technological innovation enterprises and emerging industries." Sun Jin, a partner of PricewaterhouseCoopers China Comprehensive Business Services Department, said that in 2023, with the steady progress of the comprehensive registration system reform and the introduction of more measures to support scientific and technological innovation, the international attractiveness of the A-share market will be further enhanced.

　　As for the investment industry, the strategy team of Goldman Sachs believes that with the implementation of policies and measures to stabilize growth and the continuous optimization of epidemic prevention and control measures, the unemployment rate in China will drop, labor income will improve, consumer confidence will be restored, and consumer services, medical equipment and service sectors will rebound strongly, especially in tourism, catering, entertainment and aviation industries.

　　"Next, the geopolitical situation will enter a relatively calm stage, and the equity cost and equity risk premium will gradually decline, which will help investors reinvest in the China stock market. The consumer sector is the beneficiary of economic opening up. We further increase our exposure to this sector and continue to suggest increasing the allocation of offshore China stocks. " Wang Ying said.

　　In order to better attract foreign investment into the China market, Tian Lihui, president of the Institute of Financial Development of Nankai University, believes that it is necessary to persist in promoting the high-level institutional opening-up of the capital market and make overall plans for development and security. It is necessary to continue to expand the interconnection quota, continuously increase the variety of international products, gradually liberalize the restrictions on foreign-funded shares of financial institutions, and continue to promote the internationalization of the RMB. At the same time, the capital market should be opened to the outside world with gates, there should be room for trading rules, and market supervision should be real-time and prudent to prevent foreign hot money speculation and prevent the spread of foreign financial risks.

　　Fang Xinghai, vice chairman of China Securities Regulatory Commission, also said recently that high-quality overseas capital market institutions are welcome to invest and exhibit in China. In the future, we will further improve the institutional framework for opening up the capital market, accelerate the implementation of various opening-up measures, and attract and gather more outstanding international institutions and talents to participate in China’s capital market. We will continue to improve relevant institutional arrangements, further facilitate cross-border investment by domestic and foreign investors, and better support cross-border financing development of enterprises.

　　Competing for exhibition industry in China

　　Since the beginning of this year, the policy dividends to further improve the convenience of foreign investment in China’s assets have been released intensively, giving foreign institutions a "reassurance" to enter the China market.

　　On April 26th, the CSRC issued the Opinions on Accelerating the High-quality Development of Public Offering of Fund Industry, proposing to support high-quality overseas financial institutions with long-term investment will to set up fund management companies or expand the shareholding ratio. On November 18th, the People’s Bank of China and the foreign exchange bureau jointly issued the Regulations on Fund Management of Foreign Institutional Investors’ Investment in China Bond Market, which improved and clarified the requirements for fund management of foreign institutional investors’ investment in China Bond Market.

　　The convenience of foreign-funded institutions’ exhibition industry in China has been continuously improved, and the business scope and regulatory requirements have achieved national treatment. At present, more than 10 foreign-controlled or wholly-owned securities fund futures companies, such as JPMorgan Chase, Goldman Sachs, Nomura and UBS, have been successively approved, and foreign banks such as Standard Chartered Bank have obtained fund custody qualifications in subsidiaries in China. Foreign private equity funds such as Qiaoshui and BlackRock have successively set up 38 wholly-owned subsidiaries.

　　On November 25th, Lubomai Fund announced that it had obtained the Public Offering of Fund business license issued by China Securities Regulatory Commission, becoming the second wholly foreign-owned fund management company newly established in China to conduct Public Offering of Fund business. Lubomai Fund said that the continuous opening of the financial market and the increasingly perfect business environment ruled by law have further enhanced Lubomai’s confidence and hope to further integrate into the development of China’s capital market in the future.

　　A number of foreign-funded institutions have started to exhibit in China. At the end of October, ICBC Wealth Management of Goldman Sachs, which was approved to open in June this year, launched the first wealth management product "Shengxin Junzhi Private Bank Enjoy Quantitative Equity Wealth Management Product Phase 1", with a maximum fundraising scale of 5 billion copies. Goldman Sachs ICBC Wealth Management previously said that after the deep correction in the previous period, the value of A shares is becoming prominent, and there is a large room for long-term holding.

　　As the first wholly foreign-owned public offering, BlackRock Fund has issued three equity funds and one "fixed income+"fund since it was approved in June 2021, and its products are diversified. Lu Wenjie, investment director of BlackRock Fund, said that A-shares are a market with great breadth and depth, wide investment scope, many related target companies and good liquidity. With the continuous strengthening of China’s opening to the outside world, it is believed that the integration of the global market and the China market will be a long-term trend.

　　"More outstanding international institutions entering the A-share market are investing in China’s economic growth prospects and the profitability of China enterprises &lsquo; A vote of confidence &rsquo; Being able to form a healthy competitive interaction with domestic institutions is conducive to expanding the breadth and depth of China’s capital market, and is also conducive to the continuous improvement of service capabilities of related industries and helping China’s economic development. " Tian Lihui said.

[Text/Observer NetworkBlocking open source】 According to the bidding contract signed by the Russian Saturn engine company this year published by the Russian government affairs open website, the company signed two contracts with the Equipment Department of People’s Republic of China (PRC) Military Commission, including a total of 224 D-30KP2 engines, which are scheduled to be delivered before 2020. The contract indicates that the total price of these two contracts is about 657 million US dollars according to the 2010 US dollar exchange rate, with an average price of 3 million US dollars per engine.

Signing a contract with Russia indicates that Yun -20 will enter the stage of mass production.

Screenshots of two contracts posted on the Russian government affairs website.

According to this, it is speculated that most of these engines will be used for the production of Yun -20 strategic transport aircraft and H -6K strategic bomber, in addition to supporting the maintenance of the previously purchased Il -7678 series fleet. According to the Russian network transmission, if the 170 engines in the contract are used for new aircraft, it can at least meet the requirements of manufacturing 40 Yun-20s.

According to the contents of the contract, the Sino-Russian D-30KP2 engine contract was signed in two parts, one of which was 54 engines with a price of 158 million US dollars. According to regulations, 10 units will be delivered in 2017; 12 units delivered in 2018; 12 sets in 2019; 20 in 2020.

The other part is 170 engines at a price of 499 million US dollars. According to regulations, 44 units will be delivered in 2017; 40 sets in 2018; 48 units in 2019; 38 in 2020.

It is reported that China and Russia signed two contracts to purchase D-30KP2 engines in 2009 and 2011, including 55 in 2009 and 184 in 2011. The engines stipulated in the above two contracts shall be delivered before the end of 2015.

At present, China Air Force uses D-30KP2 engines, including Il -76 transport aircraft, Il -78 tanker, H -6K strategic bomber and Yun -20 large transport aircraft newly delivered to the Air Force.

China Air Force acquired more than ten Il-76s from Russia in 1990s. After entering the 21st century, it was once planned to purchase 38 additional Il -76 and Il -78 aircraft from Russia, but because the Russian side could not deliver them, it was finally compensated by D-30KP2 engines. After 2010, China successively obtained about 10 second-hand Il-76s from Russian, Ukrainian and other countries, and continued to serve after renovation and modification.

Using these D-30KP2 engines, China has produced nearly 60 H -6K strategic bombers and equipped its troops, which also met the requirements of the test flight and initial production of Yun -20.

Zhuhai Air Show will show an improved model of Yun -20F-100 transport aircraft with domestic turbofan engine. The fuselage of the aircraft is lengthened and the engine is replaced with domestic turbofan engine.

It is normal for the special aircraft of large transport aircraft to change the engine many times in its life. The picture shows the KC-135E tanker of the US Air Force, which changed the engine model for the first time in the 1980s, from the earliest J57 turbojet engine to TF33 turbofan engine.

In the 21st century, about 136 KC-135 tankers have been replaced by CFM-56 engines, which have doubled the thrust and increased the range by 60% compared with the original J57 engine. Before the new generation KC-46 tankers came into service, they became the best performance tankers of the US Air Force.

At present, in addition to changing the models of engine test platform, aerial tanker and early warning aircraft, the number of Il -76 aircraft undertaking air transport tasks is about 24, which is equivalent to a transport aviation regiment (not fully staffed), and it is far from meeting the demand of China Air Force for strategic delivery capability.

According to the agreement signed with Russia this time, the purchased engines will obviously be used for mass production of new transport aircraft in addition to replacing the engines that have been purchased on the aircraft and need to be replaced. If, as the Russian media said, the first contract of 54 units is mainly used to meet the maintenance of the previously purchased Il -76 and Il -78 fleets, then the remaining 170 engines can meet the requirements of producing 42 Yun -20 aircraft.

Russian D-30KP2 engine

If this goal is achieved, China Air Force’s strategic transport fleet will be completely updated to Yun -20, while the current Il -76 can be changed to Il -78 aerial tanker, making up for the major shortcomings of China Air Force’s lack of tankers at present.

At the same time, a number of Yun -20 aircraft can be changed into airborne early warning aircraft platforms to enhance the strength of China’s early warning aircraft fleet.

　　Sina Auto News On the evening of July 11, 2019, a new generation of Song Pro models of BYD’s new energy dynasty family went on the market. The new car was built based on the new BNA architecture. The appearance and interior design adopted the latest Longyan 2.0 design language of BYD family, and the power part provided three power forms: gasoline /DM dual-mode hybrid/pure electric. A total of 12 models have been launched in the new car, and the price range of the whole car system is 898-219800 yuan.

　　1, BYD Dragon Face 2.0 design language, 12.8-inch rotating screen.

　　2. LED light group, DiLink2.0 intelligent network connection system and intelligent driving assistance technology.

　　3. Gasoline /DM dual-mode hybrid/pure electric rich power system

　　In terms of appearance, Song Pro adopts the design language of BYD Dragon Face 2.0, and the front face is more recognizable. The headlight department adopts full LED light group, which has the effect of lighting step by step and turning signal flow. The daytime running light adopts dragon claw elements, which also makes the headlights more recognizable.

　　According to different models, the front face design of Song Pro fuel /DM/EV models is different. The five transverse decorative strips inside the front grille of the fuel version adopt a single-layer design, and the opening area is also larger. The fog lamp style is also different from that of the electric version. On the other hand, the five grille trims of DM model have become double-layer design, and the trims on both sides of the lower enclosure have become C-shaped, and the opening area has been reduced; The grille of EV model is replaced with a closed design consisting of short chrome-plated line array decorative strips. This should be the main way to distinguish the three kinds of motivation.

　　The side of the car body has a suspended roof design, and the fender lines that are picked up at the front and rear also make the car more dynamic. The external dimensions of the Pro family in Song Dynasty are the same, with the length, width and height of 4650/1860/1700mm and the wheelbase of 2712mm respectively. The more eye-catching design for the rear of the car is the through LED taillight group. The difference between the three power models mainly lies in the tail logo.

　　The interior of Song Pro EV is also equipped with a 12.8-inch adaptive rotating suspension Pad, with a built-in DiLink2.0 intelligent network connection system, which provides basic functions such as navigation, cloud music, online broadcasting, etc. It is also compatible with more than 4 million App applications and has OTA air upgrade function.

　　In addition, Song Pro’s new energy vehicle is equipped with the unique L2 Plus intelligent driving assistance technology at the same level, including ACC-S&G stop-and-go full-speed adaptive cruise system, LDWS lane departure warning system, BSD blind spot monitoring system and other common L2 functions, as well as "black technology" such as holographic transparent image system and cloud service APP intelligent remote driving.

　　Song Pro DM offers two power models. Among them, the four-wheel drive performance version is equipped with a plug-in hybrid system consisting of a 1.5T direct injection engine and a rear axle single motor. The comprehensive maximum power of the system is 323 HP, the peak torque is 525 Nm, it is matched with a 6-speed dual-clutch gearbox, and the 0-100km/h acceleration time is 6.5 seconds. Song Pro DM four-wheel drive high-energy version added a front axle motor with a maximum power of 150 HP to form a "three-engine four-wheel drive" hybrid system, with a comprehensive maximum power of 473 HP and a peak torque of 775 Nm, which also matched the 6-speed dual-clutch gearbox, and the official acceleration time of 0-100km/h was shortened to 4.7 seconds.

　　Song Pro EV offers two power models. The high-power version and the high-power and long-life version are both equipped with a front-axle AC permanent magnet synchronous motor, with maximum power of 163 HP and 184 HP respectively and peak torque of 280 Nm. At the same time, they are equipped with battery packs with capacity of 59.1kWh and 71kWh respectively, corresponding to NEDC cruising range of 405km and 502km respectively, and their 0-50km/h acceleration time is 4.3 seconds. In terms of charging time, it takes 1 hour and 1.2 hours to fully charge the power in the high-power charging pile fast charging mode, while it takes only half an hour to quickly charge the power from 30% to 80%.

　　In terms of competing products, in fact, there are still many opponents involved in BYD’s Song Pro model, because the power system of Song Pro includes fuel, hybrid and pure electric, so the pressure of Song Pro is still quite great, but BYD has always been on a cost-effective route. Although independent brands often use the same routine, from the perspective of Song Pro’s configuration and comprehensive performance, it is still very strong in the same class, aiming at the demand of Chinese people for cars. Song Pro has certain advantages in space, maintenance costs, configuration richness and power level. If price concessions are added, the sales of Song Pro should still perform well.

　　Thanks to the development of new energy in recent two years, BYD’s brand awareness has been greatly improved, especially the performance made by Qin and Tang, which has been recognized by more and more consumers. Song Pro took the opportunity to appear, continuing the cool dragon face design, large-size optional screen in central control, and superior DM performance. In fact, these three points alone can get rid of competitors in the market. Although the new energy policy has been recycled, I think manufacturers can still attract consumers to buy it through their own subsidies.

CCTV News:April 8th is the International Day for the Protection of Rare Animals. We walked into Jiangcheng County, Pu ‘er, Yunnan Province, one of the habitats of Asian elephants, to see the activities of local Asian elephants.

Early in the morning, the reporter followed the Asian elephant monitoring team to the Manlao River in Dashujiao Village, Kangping Town, Jiangcheng County. According to the staff, there were 42 wild Asian elephants in this area recently.

In view of the shortage of food for elephants in winter, corn, sugar cane, bananas, etc. are specially planted in some specific areas for elephants to eat. These places are also called "elephant canteens". However, at this time, corn and sugarcane have just entered the cultivation period, and there is relatively little food in the wild, which leads to more frequent activities of elephants entering the village and is prone to injury accidents. Therefore, the local people deliberately artificially feed at the entrance of some villages.

In addition to feeding the Asian elephants well, the daily focus of the staff is to monitor the range of activities of the Asian elephants.After locating the elephant activity area, the staff immediately controlled the roads along the way and placed warning signs. At the same time, they issued early warnings through WeChat group, monitoring and early warning platform and village broadcasting, and tracked the monitoring activities with drones.

Yunnan Shuangbai: Photographers shot a lot of rare green peacock videos.

Green peacock is a national first-class protected wild animal, mainly distributed in Yunnan Province and some Southeast Asian countries. At present, the number in China is only between 550 and 600. Green peacocks are timid and difficult to approach, so there are few related videos except a few pictures taken by infrared cameras. Recently, photographers have been crouching for 6 days, shooting a large number of green peacock videos with a 360-degree panorama camera.

In the picture, these green peacocks are foraging by the river bed. It’s the breeding season of green peacocks. During the period of crouching, the photographer photographed that these green peacocks sometimes play, sometimes take a sand bath in the river valley, and sometimes unfold a long tail screen.

Gu Bojian, a teacher at the School of Ecological Environment of Ningxia University: "There are both adult birds and adult birds in the picture. The male green peacock of an adult bird has a shorter tail screen than that of an adult bird. This season is the breeding season for green peacocks. The males have long tail screens, and the feathers in other parts of their bodies are also the most glamorous. Green peacocks can get rid of parasites and keep their feathers bright through sand bath. "

According to experts, this group of green peacocks in front of us was photographed by the infrared camera of the Management and Protection Bureau of Dinosaur River State Nature Reserve in May last year. At that time, they were still chicks with gray-black feathers. After nearly a year, these green peacocks have grown bright feathers and long tail screens.

Wang Sibeng, Director of the Management and Protection Bureau of Dinosaur River State Nature Reserve in Shuangbai County: "As the only original peacock population in China, there are about 550&mdash; 600, all distributed in Yunnan Province. According to the monitoring data of the nature reserve, there are about 360 native green peacocks in Shuangbai County, accounting for more than half of the national population. "

　　In 2022, the No.1 Document of the Central Committee pointed out that we should vigorously promote the construction of digital villages, promote the development of smart agriculture, and promote the integrated application of information technology and agricultural machinery and agronomy. The "14th Five-Year Plan" and the outline of the long-term goal in 2035 proposed to build smart agriculture and accelerate the modernization of agriculture and rural areas. An agricultural intelligent revolution with intelligent agriculture as its manifestation has arrived. In this issue, relevant experts are invited to discuss the issue of smart agriculture.

　　Moderator: Xu Xiangmei, director and researcher of the Theory Department of Economic Daily.

　　Deep integration of information technology and modern agriculture

　　Moderator: What are the distinctive features of smart agriculture that are different from traditional agriculture? Why should we attach great importance to smart agriculture?

　　Li Daoliang (Director, National Digital Fisheries Innovation Center, China Agricultural University): Smart agriculture is the product of deep integration of new generation information technologies such as Internet of Things, cloud computing, big data, spatial information technology, blockchain and artificial intelligence, modern agricultural planting and breeding technology, and the industrial chain of agricultural products processing, circulation, trading and consumption. It is the "ecological integration" and "gene recombination" of modern information technology and the whole industrial chain of agricultural production, operation, management and service.

　　The main features of smart agriculture are as follows.

　　First, agricultural production factors are digitized, networked and online. Using advanced sensing, remote sensing and machine vision, the information of agricultural planting and breeding environment, the growth information of planting or breeding objects, and the working condition information of production machinery and equipment can be digitally marked and obtained. Using Internet, 5G, narrowband Internet of Things, satellite communication and other network communication technologies, remote digital information scheduling is realized.

　　Second, the regulation and decision-making of agricultural production process is cloud-based and intelligent. Based on the massive data of the production process, we make full use of big data and artificial intelligence technology, and process the data with the help of agricultural cloud computing platform to generate the optimal growth regulation model of agricultural animals and plants, so as to realize the intelligent regulation of the whole production process.

　　The third is the synergy of the whole link, whole process and whole chain of agriculture. Through the agricultural cloud computing platform, the distributed agricultural production system, logistics system, trading system and consumption system are connected into an organic whole, so that agricultural production, operation, management and consumption can be optimized in coordination with the main work.

　　The fourth is the credit and safety of agricultural management. All the data of agricultural production, circulation, transaction and consumption are uploaded and stored in the blockchain shared distributed database through the blockchain decentralization technology, forming an unbreakable account book that can be consulted by consumers and buyers, making agricultural management credit and safe.

　　The significance and function of developing intelligent agriculture are mainly reflected in the following aspects.

　　Promote the conservation and efficient utilization of resources and the green development of agricultural science. Through the Internet of Things, big data, artificial intelligence, robots, intelligent equipment and other technologies and breeding techniques, planting and breeding operations can get rid of the natural environment and human dependence, and build an agricultural production automation system that integrates environmental physiological monitoring, crop model analysis and precise adjustment, so as to improve labor production efficiency, land output rate and resource utilization rate. Through digital measurement and control, we can meet the needs of crop growth, ensure resource conservation and avoid environmental pollution, and realize the green development of agriculture. At present, agricultural developed countries have realized that one person cultivates 5,000 mu of land, one person produces 500 tons of vegetables annually, one person grows 1 million potted flowers, one person raises 200,000 chickens and produces 180,000 eggs a day, and one person raises 10,000 pigs, 200 cows and 100 tons of fish, completely changing the problems faced by traditional agriculture with extensive management, weak competitiveness and low resource utilization rate.

　　Promote agricultural standardized production and ensure "green and safety on the tip of the tongue". Real-time dynamic monitoring of soil, atmospheric environment and water environment through digital, networked and intelligent equipment to make it meet the environmental standards of agricultural production; All aspects of production can also be produced by intelligent equipment according to certain technical and economic standards and specifications; Through digital and intelligent equipment, the quality of agricultural products is accurately detected in real time to ensure that the final agricultural products meet the corresponding quality standards. With the help of Internet, QR code, radio frequency tag, blockchain and other technologies, we will establish an information platform for agricultural product quality and food safety that can be traced and shared in the whole process, improve the supervision system of agricultural product quality and safety process from farmland to table, and ensure the people’s "green and safety on the tip of their tongue".

　　Promote the integration and branding of agricultural management. The application of information technology has broken the space-time geographical limitation of agricultural market, and the data of agricultural materials procurement and agricultural products circulation will be monitored and transmitted in real time, effectively solving the problem of information asymmetry. Use the e-commerce platform to expand the sales channels of agricultural products, build an integrated agricultural product management system through self-operated bases, self-built websites and independent distribution, and promote the market marketing and brand operation of agricultural products.

　　Promote the integration of primary, secondary and tertiary industries. The digitalization, networking and platformization of agriculture will guide the development and alliance of new agricultural business entities such as large professional households, family farms, farmers’ professional cooperatives and excellent enterprises, promote the close connection of related industries such as agricultural product production, circulation, processing, storage and transportation, sales and service, realize the effective allocation of agricultural factor resources, and make the industry and factor agglomeration change from quantitative collection to qualitative change, so as to rebuild the whole agricultural industrial chain and realize the cross-infiltration and integrated development of agriculture and secondary and tertiary industries.

　　Intelligent management aims at system optimization.

　　Moderator: What is the development status of smart agriculture in developed countries? What experience does it have in the research, development and application of new smart agriculture technologies that are worth learning from in China?

　　He Yong (Director, Digital Agriculture and Rural Research Center, Zhejiang University): The United States is a typical modern agricultural country in the world, with about 3.5 million people directly engaged in agricultural production, which not only feeds 300 million Americans, but also becomes the largest exporter of agricultural products in the world. Full mechanization and rapid development of digital technology have laid a solid foundation for the development of its smart agriculture. At present, the United States has formed a sophisticated and large-scale intelligent agricultural production system. 69.6% of farms use sensors to collect data, and agricultural robots are used in agricultural production such as sowing, spraying and harvesting.

　　As the world’s largest agricultural drone spraying country, Japan mainly uses the agricultural Internet of Things as the information source, applies a large number of agricultural robots, and constantly pursues labor-saving and refined agricultural production to solve the problem of agricultural labor shortage.

　　The characteristics of smart agriculture in Europe, America, Japan and other developed countries are based on the development trend of modern agriculture, combined with the actual agricultural production in their own countries to carry out theoretical and practical research on smart agriculture. With the support of modern information technology, we should give full play to the role of smart agricultural equipment, and apply technologies such as Internet of Things, artificial intelligence, big data and 5G to consider crops, soil, environment, meteorology, equipment and personnel as a whole system, so as to realize intelligent management with the goal of overall optimization of the system.

　　Developed countries have the following experiences in the research, development and application of smart agricultural technology, which are worth learning from in China.

　　First, starting with improving productivity and solving the bottleneck problem of agricultural production. The Netherlands, Israel and other countries are seriously short of fresh water resources, so they vigorously develop facility agriculture, implement soilless culture and fine spray and drip irrigation systems. Japan’s agricultural labor force is aging and seriously inadequate, and it vigorously develops agricultural drones and agricultural robots, greatly improving operational efficiency. South China is also facing the shortage of labor force and the availability of agricultural inorganic materials in hilly and mountainous areas. We should develop multifunctional small-scale operation equipment, realize the substitution of machines and solve the problem of mechanized operation in hilly and mountainous areas. The main grain producing areas should implement full mechanization to improve labor productivity. Economically developed areas can study the establishment of unmanned or few farms, orchards, pastures, fishing grounds, etc., to improve the level of agricultural modernization.

　　Second, the implementation of standardized planning and operation is the basis and condition for the development of smart agriculture. Standardized planning and refined management of farmland, orchards and pastures in developed countries have created conditions for large-scale and efficient use of intelligent agricultural equipment, greatly improving operation efficiency, yield and quality. China’s farmland, orchards and pastures need to promote standardized planning as soon as possible, formulate standardized operation specifications, and develop high-efficiency supporting equipment to create conditions for large-scale mechanized operations.

　　Third, make full use of modern science and technology to plug in the wings of science and technology for agriculture. A large number of foreign countries use aerospace technology and meteorological data to achieve rapid and accurate acquisition and intelligent management of farmland information. With the development of Internet of Things, big data and 5G technology, especially the application of high-resolution satellite and Beidou positioning system, it is expected to realize real-time dynamic acquisition of crop and animal and plant growth information, and dynamically adjust and control temperature, humidity and illumination according to crop growth requirements, and accurately spray fertilizers and fertilizers.

　　The development of smart agriculture in various places has achieved practical results.

　　Moderator: What is the development status of smart agriculture in China? What are the successful experiences and innovative explorations of smart agriculture development in various places?

　　Kang Chunpeng (Associate Research Fellow, Information Center, Ministry of Agriculture and Rural Affairs): China’s agricultural and rural informatization development level is still in the primary stage, but the agricultural industry is accelerating its transformation towards digitalization, networking and intelligence, and the consumer Internet continues to extend and expand to the industrial Internet. According to the monitoring of the Information Center of the Ministry of Agriculture and Rural Affairs, in 2020, the informatization level of agricultural production in China will be 22.5%, including 18.5% for field cultivation, 23.5% for facility cultivation, 30.2% for livestock breeding and 15.7% for aquaculture. In recent years, China’s smart agriculture has gradually achieved results, and the level of intelligence and unmanned has gradually improved, showing the following highlights.

　　First, new products and technologies are booming. Modern information technology is widely used in all aspects and fields of agricultural production, and new products, technologies and models emerge one after another. The digital transformation of agriculture has been accelerated, and the traditional agriculture has been transformed into intelligence. Intelligent identification systems for crop moisture, seedling condition, diseases and pests and disaster monitoring in the field and intelligent robots for farming and harvesting have been continuously developed. In particular, products such as automatic harvesting equipment, agricultural sensors, camera monitoring, pest monitoring and early warning have been widely used.

　　Second, no one or few farms broke ground. The rural network infrastructure has been continuously consolidated, especially the maturity and popularization of big data, 5G and artificial intelligence technologies, which provide basic conditions for the development of unmanned or few farms. In Changsha, Hunan, Wuhu, Anhui, Sanjiang, Huzhou, Zhejiang, Chongzhou, Sichuan, Foshan, Guangdong and other places, no one or few farms broke ground, and all farm production operations were completed through remote control of facilities, equipment, machinery and so on, automatic control of the whole process or autonomous control of robots.

　　Third, the construction of big data has achieved initial results. From the national level, the sharing of government data resources and the integration of information systems have achieved phased results, the national integrated government service platform has been basically completed, and the pattern of co-construction and sharing of government data resources has basically taken shape. From the perspective of local practice, Anhui, Zhejiang, Jiangsu, Guangxi and other places have actively promoted the construction of big data in agriculture and rural areas, and successively built big data platforms. Zhejiang is vigorously promoting the digital reform of "agriculture, rural areas and farmers" throughout the province.

　　Fourth, market players have become a new force. Market players are becoming an important force in building smart agriculture. Large enterprises have entered the field of smart agriculture. The three major telecom operators and Internet companies such as Huawei, Alibaba and Tencent have laid out smart agriculture. Sinochem, Zoomlion and Country Garden have begun to enter smart farms. In addition, agricultural enterprises also take the initiative in the digital transformation. Traditional agricultural enterprises such as COFCO, Beidahuang, New Hope and Haisheng Fruit Industry vigorously develop smart planting, smart animal husbandry, smart fisheries and smart processing.

　　Since 2019, Zhejiang has taken the lead in building a "digital agricultural factory" in the country, and carried out systematic integration and comprehensive application of digital technology and equipment around the production environment, production process, quality and safety, circulation marketing and technical services. After several years of practice, in 2021, guidelines for the construction of digital agricultural factories, digital fishing grounds and pig farms were successively issued. Shui Mu Vegetable Factory in Deqing County integrates advanced technology into production management, product marketing, quality control, ecological protection and other links, achieving an annual output of 2 million kilograms of tomatoes, with an efficiency of 30 times that of traditional fields; Tongxiang Huateng Animal Husbandry uses technologies such as Internet of Things, artificial intelligence, bio-ear tags and blockchain to promote the digital transformation of animal husbandry and create a safer, more productive and fully automatic breeding environment, saving 80% labor and 60% water.

　　Zibo, Shandong Province took the lead in building a digital agricultural rural central city in China, focusing on five key tasks: agricultural production and processing, agricultural product warehousing and logistics, agricultural product marketing, integrated development of agriculture and tourism, and consolidating grassroots foundation, and building a smart sharing "cloud brain", an efficient and high-quality "cloud industry", a regional center "cloud market", a convenient and inclusive "cloud finance" and a new service "cloud village". In 2021, 4.54 billion yuan of major special funds for rural revitalization will be set up, and 40 key digital agriculture and rural projects will have an investment of 5.186 billion yuan, and 30 typical application scenarios and 10 smart towns will be built.

　　From a practical point of view, the development of smart agriculture in many places has achieved remarkable results and formed experience for reference. First of all, give full play to the role of market players, establish an effective market in full accordance with the laws of economic operation and information development, and stimulate the vitality of various market players. Secondly, we should play the role of a promising government, guide market expectations with policies, clarify the investment direction with planning, incite social capital with finance, and regulate market behavior with the rule of law. Finally, do a good job in pilot demonstration. Smart agriculture is an advanced form of agricultural informatization, which involves relatively advanced technology and has great market risks. On the basis of fully respecting farmers’ dominant position, we should show them, lead them to work and earn money, and inspire them to use modern information technology to develop production and improve their lives.
