　　How to increase production and increase efficiency of grain and oil crops? Recently, the reporter learned that the National Agricultural Technology Center, together with the Expert Steering Group of Scientific Fertilization and Water-saving Agriculture of the Ministry of Agriculture and Rural Affairs, has selected five practical technical models for increasing fertilizer and water production and increasing efficiency, which are suitable for the production of grain and oil crops such as rice, wheat and corn. The arrangement is as follows, for the reference of farmers.

　　The foliar fertilization technology model of "one spray and more promotion" for grain and oil crops　

　　This model is suitable for grain and oil crops such as rice, corn, soybean, etc. In view of the realistic scenes such as late fertilizer removal, high temperature and drought, scanty rain, and occurrence of diseases and pests, water-soluble fertilizers, stress-resistant agents, regulators, pesticides and fungicides are scientifically mixed and sprayed as needed to promote the stable growth of strong seedlings, post-disaster recovery, grain filling maturity, yield increase and pest control.

　　The technical points are as follows: firstly, the fertilizer is carefully selected, and the quick-acting nitrogen fertilizer, potassium dihydrogen phosphate, water-soluble fertilizer with large elements and medium and trace elements are selected for the later supplementary fertilizer; Water-soluble fertilizers containing humic acid, amino acids and trace elements are selected for adjusting nutrition; The growth regulator can be brassinolide, triacontanol, indolebutyric acid, etc. Apply pesticides according to the occurrence of pests and diseases. Fertilizer products should be registered or put on record by the agricultural and rural departments. The second is to optimize the combination. Neutral or acidic fertilizers can be directly mixed with pesticides with similar pH values, and mixing tests should be carried out before mixing alkaline fertilizers with pesticides. The third is efficient spraying, using modern equipment such as unmanned aerial vehicle, high gap spray bar sprayer and vehicle-mounted stretcher to spray.

　　Technical model of "lateral deep fertilization" for rice　

　　Integrate lateral deep fertilization, remote sensing diagnosis, and drone topdressing, give full play to the advantages of agricultural machinery and agronomy, and accurately control the dosage of fertilizer varieties, the proportion of nutrient forms and the timing of fertilization, so as to realize mechanized and precise fertilization in the whole growth period.

　　Technical points: First, the variety of base fertilizer is optimized, and the special formula fertilizer for slow (controlled) release is selected, which has uniform particles and moderate hardness and is convenient for machine application. Secondly, fertilization and transplanting should be synchronized, and the fertilizer should be evenly and quantitatively applied to the sides of the seedlings with a depth of 4-6 cm, and the nutrients are concentrated in the root zone, which is sufficient and easy to absorb. The third is intelligent nutrition diagnosis, and multi-spectral remote sensing diagnosis is carried out in the middle and late stage to guide the UAV to apply fertilizer accurately, efficiently and as needed, supplement nutrition in the later stage, enhance photosynthesis, enhance stress resistance, prevent premature aging, protect big ears, increase grain weight and achieve high yield.

　　Technical mode of "mechanical deep application+topdressing by drone+one spraying and three prevention" for wheat　

　　Integrate seed and fertilizer sowing together, "one spraying and three prevention" technology, subsoiling layered fertilization seeder, unmanned aerial vehicle and other equipment, supporting slow (controlled) release of fertilizer, overall planning of base fertilizer topdressing, combination of quick-acting slow release and compatibility of nutrient forms, and solve the problems of large loss of base fertilizer and premature aging in the later stage.

　　Key technical points: First, mechanical deep application, selecting slow (controlled) release new fertilizers, rotary tillage after spreading, the depth is more than 20 cm, or adopting simultaneous sowing of seeds and fertilizers to ensure nutrient supply and promote root growth. Second, the drone topdressing, according to the situation of wheat seedlings, strengthen fertilizer operation, focusing on topdressing wheat fields that are frozen in early spring and weak seedlings in late sowing to promote growth and improve tillering. The third is to spray three defenses, mixed with water-soluble fertilizers, regulators, pesticides and fungicides, etc., to increase grain size and weight, and prevent pests and diseases.

　　Technical model for increasing yield of ultra-deep subsoiling maize in dryland by one-step layered fertilization　

　　Integrate key technologies such as super subsoiling and three-layer fertilization to effectively solve long-term problems such as weak root system and late fertilization.

　　Technical points: First, ultra-deep loosening is increased from 25-30 cm to 50 cm, breaking the bottom of the plow, fully storing natural precipitation, and promoting the root to be tied to 50 cm. The second is layered fertilization. The fertilization depth is divided into three layers: shallow, medium and deep. The seed fertilizer depth is 8 cm, the middle fertilizer depth is 16 cm, and the deep fertilizer depth is 28 cm. The common compound fertilizer is replaced by functional fertilizers with long-term effect and root growth promotion, so as to realize accurate supply of nutrients.

　　Production technology model of bill of lading with integrated water and fertilizer for corn drip irrigation　

　　On the basis of drip irrigation water and fertilizer integration technology, measures such as compact and dense varieties, reasonable close planting, dripping seedling emergence, chemical control and lodging prevention and control of pests and diseases are integrated.

　　Key technical points: First, crop density is increased by more than 30% by strengthening water and fertilizer supply support, from less than 5,000 plants to more than 6,500 plants. Second, the coupling of water and fertilizer, drip with fertilizer after sowing to promote the whole seedling to be strong, supply water and fertilizer on demand, in stages, in a balanced and accurate way throughout the whole process, and move nitrogen and potassium backward to ensure that fertilizer is not removed in the later stage. Third, chemical control and lodging prevention, planting plots with high density, overgrowth and easy lodging, using special chemical control agents during 6-8 leaves spreading to enhance lodging resistance and drought resistance, and realize short stalks, large ears and high yield of crops.

　　Zhongxin. comBeijing, August 24th: Six months after the conflict between Russia and Ukraine, five major variables have influenced the trend.

　　The author is sweet

　　It has been half a year since the conflict between Russia and Ukraine broke out, and there is still no sign of a ceasefire. However, this "the biggest geopolitical crisis in Europe since World War II" has completely changed the world situation: multinational economies have not yet emerged from the shadow of the epidemic, and they are facing inflation, supply chain disruption and energy crisis; The west and Russia are in the same boat, tearing the already fragile international security pattern.

　　There are many disputes. It is widely believed that this planned "lightning raid" operation is likely to last for several years. The coming winter may become the "key node" of the conflict, among which, five variables may affect the future trend.

　　Stretch for half a year

　　Has the Russian-Ukrainian conflict entered a new stage?

　　Since August, artillery shells have been falling near the Zaborozh nuclear power plant in Ukraine, causing many concerns about the risk of nuclear disaster. As early as March this year, the Russian army claimed to have controlled the Zaporoge nuclear power plant, but for several months, the artillery fire has not stopped, as if it were a microcosm of the dawn of a ceasefire.

　　Since Russian President Vladimir Putin announced the launch of a special military operation in Donbass on February 24th, at the end of March, Russia declared that the first phase of military operation was basically completed and it would focus on "liberating" Donbass in Udon. As the Russian army advanced step by step, in July, Russia completely controlled Udong Lugansk, and Uzbekistan admitted its defeat.

　　Unlike the Russian army seeking "steady and steady progress", the Ukrainian army has recently shifted its offensive focus to the southern front, and has repeatedly announced that it is planning a massive counterattack.

　　There were many attacks on military bases and ammunition depots in Crimea, and Ukraine did not formally admit its responsibility, but Zelensky indicated that the war "started in Crimea and ended in Crimea".

　　The British Ministry of Defence predicts that the Russian-Ukrainian conflict will soon enter a "new stage", forming a 350-kilometer-long front extending from Zaporoge to Hellson.

　　As the conflict between Russia and Ukraine continues, the five major variables may have an impact on the situation in Russia and Ukraine.

　　Variable 1: Ling Dong is coming.

　　Climate is expected to become one of the key variables soon.

　　Recently, Ukraine has repeatedly "let out the wind", hoping to win at least one tactical victory before winter. Ermak, director of the Ukrainian President’s Office, also pointed out that Ukraine must make substantial progress before the winter, otherwise Russian troops will have more time to stabilize the battlefield situation, and it will become more difficult for Ukrainian troops to fight back.

　　After all, Moscow once defeated Napoleon and Hitler’s army with the help of "General Winter". Now, it has energy weapons in hand and has repeatedly "carried natural gas" to make European countries.

　　Although Europe follows the US energy sanctions against Russia, at present, it is more of a "bite" by sanctions. Energy bills in many countries have soared, and people are worried about heating in winter.

　　And how much energy do troubled European countries have left to support Ukraine?

　　Bloomberg bluntly said, "No matter what indicators are used, Putin is winning the energy war."

　　Variable 2: Inflation Test

　　The ongoing conflict between Russia and Ukraine is also aggravating the global inflation risk, laying a "hidden danger" for future changes in the situation.

　　International food prices and crude oil prices fell in August, but the gradual cooling of the commodity market was not quickly reflected in the people’s living costs, and the inflation rate in some countries continued to rise to new highs for decades.

　　According to the data released by Eurostat on August 18th, the inflation rate of 19 countries in the euro zone was 8.9% in July, a record high.

　　At the same time, the global food supply is facing uncertainty. Although Russia and Ukraine rarely reach a grain transportation agreement, ships carrying hundreds of thousands of tons of Ukrainian agricultural products are shipped from the Black Sea, but it is obviously not enough to solve the global "hunger".

　　UN Secretary-General Guterres stressed that at present, Russian fertilizer and agricultural exports still face "obstacles".

　　The analysis pointed out that the outbreak of the Russian-Ukrainian conflict hit the world economy that has not yet shaken off the impact of the COVID-19 epidemic, and related sanctions pushed up prices in Europe and the United States, and the pressure of inflation on residents’ purchasing power was testing the support of countries to Ukraine.

　　Variable 3: Western military aid

　　Under heavy pressure, how much practical assistance can the United States and the West provide to Ukraine?

　　Western media are not sure about this, because the western camp that originally held a group has now "split".

　　On the one hand, the United States is still taking the lead in "arching the fire", including providing about 10 billion US dollars of military support to Ukraine. Poland and Baltic countries also continue to advocate full support for Ukraine.

　　In contrast, many European countries have some "insufficient stamina". France and Germany, in particular, seem to be more eager to reach a quick solution through negotiations.

　　The database of "Tracking Aid to Ukraine" under the Kiel Institute for World Economics in Germany also shows that in recent months, the aid of six European countries to Ukraine has plummeted, and in July, no new bilateral military aid commitments were provided to Ukraine.

　　Coffman, director of the Russian Research Program of the US Naval Analysis Center, believes that European aid may have reached its limit, which will force Uzbekistan to go on an "ammunition diet".

　　Variable 4: Nuclear disaster risk

　　From Chernobyl to Zaporoze nuclear power plant, the shadow has never dissipated. Recently, the attention around the nuclear disaster has been heating up again, and the leaders of Britain, France, Germany and the United States have urged all parties to maintain military restraint.

　　The largest nuclear power plant in Europe has long been under Russian control, and Ukrainian technicians are responsible for its operation. However, the two sides have been repeatedly pulling on the attack and defense of nuclear power plants, from real guns to "information warfare."

　　According to Ukrainian statistics, Russian troops regularly shelled the nuclear power plant area, and many radiation monitoring sensors around the storage of spent fuel facility of the nuclear power plant were damaged due to Russian attacks. Zelensky also specially added a "fire", saying that if a nuclear disaster occurs, it will affect the whole of Europe.

　　The Russian army issued a statement, claiming that the Ukrainian army repeatedly used artillery to attack the nuclear power plant area, and questioned Uzbekistan as a bargaining chip for seeking Western support. Because some diplomats have hinted that the nuclear attack is regarded by western countries as one of the "red lines" of the situation in Russia and Ukraine, "unless it crosses the red line, (the West) has no will to take further action."

　　So, will there be a more terrible disaster than Chernobyl?

　　At present, preventing the escalation of the situation remains the primary choice of all parties to the conflict. UN Secretary-General Guterres went to Uzbekistan for mediation and consultation. French President Macron also spoke to Putin, who agreed to the French proposal to send an IAEA expert team to the nuclear power plant.

　　Variable 5: popular support

　　In the eyes of some foreign media, the next biggest "variable" may lie in the attitude of people in western countries.

　　Some people who originally supported Ukraine are now "tired" of the conflict. Among them, a survey of 10 European countries shows that 42% of the respondents believe that the government pays too much attention to Ukraine compared with its own troubles.

　　Accompanied by this, some diplomats and observers have noticed that some western countries have avoided specific measures against Ukraine for fear of getting "cold support" from the people, and even become increasingly reluctant to openly oppose Russia.

　　However, the cooling of public opinion does not mean the end of the conflict. The analysis believes that in view of the very contradictory positions of all parties, there is still no solution to the Russian-Ukrainian conflict. Kalachev, a Moscow political analyst, pointed out that "the war may last for several years" because neither side seems to consider a ceasefire. It remains to be seen what kind of trade-offs will be brought about by the game of great powers. (End)

　　[Aika Auto 2020 Guangzhou Auto Show Original]

　　At the 2020 Guangzhou Auto Show, which opened a few days ago, the FAW Toyota Zeze hybrid version of the twin-engine model was officially unveiled. The overall design of the new car will continue the current fuel version, but the power will be equipped with a hybrid system based on a 2.0L engine, and the fuel consumption will be further reduced compared with the fuel version.

　　The overall design of FAW-Toyota Yize hybrid twin-engine model should continue the fuel version, but it has changed in appearance and interior details, highlighting the identity of its hybrid version.

　　In terms of power, the new car is likely to be equipped with a hybrid system consistent with Lexus UX. This hybrid system consists of a 2.0L naturally aspirated engine and a motor, in which the maximum power of the engine is 107kW(146 HP), the maximum torque is 188Nm, the maximum power of the motor is 80kW(109 HP), the peak torque is 202Nm, and the combined maximum power of the system is 135kW(184 HP). Toyota already has two hybrid systems based on 1.8L and 2.5L. With the addition of the 2.0L hybrid system, Toyota’s hybrid system camp will become more powerful.

Since 2009, China has surpassed the United States to become the world’s largest automobile producer and consumer market. In the following ten years, China’s automobile market has undergone earth-shaking changes, from the initial "market for technology" to "overtaking by changing lanes" under the wave of electrification. Of course, "lane-changing overtaking" can’t just be said by mouth, but it should be realized through the core technology of completely independent new energy vehicles. At the same time, it is necessary to be able to independently produce world-class high-quality new energy vehicles in order to realize the real "lane-changing overtaking".

Looking at the current independent brands, it is obviously BYD, the new energy leader, who is most likely to achieve "overtaking in different lanes". Especially since its flagship model "Han" came out, its sales volume has exceeded 10,000 for several months in a row, and it has become the benchmark product of China brand medium and large cars. In the fierce competition market, why BYD Han can achieve excellent results, the super-high product quality is definitely the core factor. In March, 2021, BYD held the activity of "Tempering-BYD’s Quality Journey", which made us really see BYD’s quality standards and intentions.

Safety is the core, and BYD Han was tempered like this.

There is a popular saying in the automobile circle: making cars that are not aimed at safety is hooliganism. BYD has always spared no effort in terms of safety. As the flagship model of BYD, Han has become an "industry leader" in the safety field.

It is understood that in the process of vehicle development, BYD has carried out a large number of simulation designs for safety, and simulated the passive safety of the whole vehicle, system, subsystem and parts in the event of collision through mathematical models. In order to reach the safety level defined in the planning, Han adopted a high-safety car body, in which 43 pieces of military-grade thermoformed steel were used, and BYD Han used 97kg of thermoformed steel in body-in-white, which not only ranked first among China brand mass-produced cars, but also nearly twice as much as the second one, creating "invisible" protection and safer driving experience for consumers.

There is a saying that what you get from the paper is shallow. For car safety, nothing is more convincing than a crash test. The vehicle collision laboratory built by BYD with huge investment can not only carry out basic frontal, offset and side collision tests, but also carry out frontal 40% overlapping deformable rigid barrier collision, frontal 25% overlapping rigid barrier collision, rear-end collision, tumbling and column collision, and even real collision between two vehicles at high speed. It is one of the most advanced vehicle safety collision laboratories in the world.

The outstanding collision laboratory, to a great extent, represents BYD’s extra care in safety. In addition to the common crash tests such as frontal, side and rear-end collision before listing, Han also conducted more stringent and complicated safety tests for the complexity of road traffic and the characteristics of new energy vehicles, such as frontal collision with a top speed of 120km/h and ultra-difficult small offset collision, so as to ensure the safety of users in extreme traffic accidents to the maximum extent.

Of course, for new energy vehicles, in addition to the safety of vehicles, battery safety is the focus of everyone’s attention. For this reason, BYD has launched a blade battery. In this activity, the acupuncture test was displayed on the spot. Compared with the ternary lithium battery, it exploded and caught fire instantly after puncture, and the blade battery completed the puncture test steadily, which showed us BYD’s strength in leading the global power battery safety to a new height.

Besides safety, BYD Han’s high quality is reflected in its high reliability and long life. When we walked into BYD Parts Testing Center, there were a series of test stands, such as steering system laboratory, suspension system durability test platform, vehicle four-column test bench and environmental warehouse, MAST multi-axis simulation vibration test bench, 24-channel road simulation test bench, etc. The repeated tests made BYD Han more reliable. Not only that, BYD Han has to complete the "three highs" test in a harsh and extreme environment, and run on real roads in Heilongjiang, Tibet, Hainan Island and other places in the country through the team’s self-driving mode, which makes BYD dare to target the life of the whole vehicle at 600,000 kilometers, which is twice as much as that of the same class.

The sales volume is only the beginning, and BYD Han leads the brand upward.

As mentioned above, BYD Han has sold more than 10,000 cars for several months in a row, and in terms of sales volume, it is second only to the "Three Musketeers" (Audi A6L (parameter picture), Mercedes-Benz E-Class, BMW 5 Series) models with a monthly sales volume of 10,000, which is far away from other competitors. As the only new energy vehicle with a monthly sales of over 10,000 yuan in the current medium and large car market, Han can be said to have achieved a milestone breakthrough, marking the official entry of China brand into the same class car head camp.

Byd Han, as a heavyweight model of BYD for ten years, has a more important significance besides sales volume, which is to lead the brand upward and lead its own brand to hit the high-end market. When it comes to the upward trend of China’s automobile brand, behind it is the upward trend of technology. As BYD’s flagship model, Han has 12 best in the world and 9 best in China, setting a benchmark for the safety, performance and luxury of new energy vehicles. It can be said that with strong technical strength, Han has subverted consumers’ cognition of the mid-to-high-end car market, and made a solid step on the road to the breakthrough of China brand cars.

When major car companies are still simply pursuing single indicators such as battery life, BYD Han, which integrates the world’s leading hard-core technology, has set a new benchmark for the new energy industry. Byd Han’s strong product strength in performance, safety, luxury, design and other aspects has established the identity of the flagship model and made people see the powerful strength of the current China automobile brand.

In addition, the appearance of BYD Han not only created a new standard of global new energy vehicle technology and quality, but also rewritten the market structure of new energy vehicles and traditional fuel luxury vehicles. As the saying goes: hearing is empty, seeing is believing. Through the activity of "Quality Journey of BYD", we can see BYD’s focus on quality, and it is this focus that enables it to always lead the new energy market. Nowadays, with the arrival of the stock era, super-high quality is the first factor to impress consumers, which also gives us reason to believe that BYD will create more brilliant achievements in the future.
