Accelerate the transformation of agricultural development mode to realize plant protection and drone "reducing medicine and increasing efficiency"

[ China Agricultural Machinery Industry News ] In recent years, plant protection drones have experienced a development process from scratch to precision, and are increasingly welcomed by farmers. Plant protection drones are constantly striving on the road to innovation. We will strive to achieve "reduction of drugs and efficiency."

Accelerate the transformation of agricultural development mode to realize plant protection and drone "reducing medicine and increasing efficiency"

In April, when we arrived at the busy season, various crops were started to prevent pests and diseases. As far as China's current level of agricultural science and technology development is concerned, the use of pesticides is still an effective and economic measure to control pests and diseases.

When talking about the issue of ecological environmental protection, Gong Jianming, member of the Standing Committee of the National People's Congress and vice chairman of the Central Committee of the Agricultural and Labour Party, said that pesticides have long been controlling the occurrence of pests and diseases, protecting the safe growth of crops, increasing crop yields, and promoting the sustained and stable development of the national economy. All aspects have played an important role. However, at present, the environmental pollution problems caused by pesticides cannot be ignored.

It turns out that the high dosage of pesticides and low efficiency have become a prominent problem in the prevention and control of agricultural pests and diseases in China. According to statistics, in the past five years, the national pesticide use amount is about 310,000 tons (100%, that is, the equivalent concentration), the preparation is more than 1 million tons, and the pesticide utilization rate is only 35%.

At present, there are more than 500 kinds of synthetic chemical pesticides. The use of high-yield and low-effective pesticides not only causes serious environmental pollution, but also causes harm to human health.

With the one-year advancement work of the Ministry of Agriculture in 2016, the plant protection machinery such as drones has gradually been accepted.

Recruit: born with the "reduction of drugs and efficiency" attribute

Pesticide reduction is a systematic project, and scientific reduction should be carried out in steps, sub-regions and sub-crops. The plant protection drone has many advantages, which can realize intelligent operation, cross-regional and cross-species operation. It has good power durability, large drug load, and the level of intelligent operation is very mature. It is not affected by the topographic environment and crop height. It works in flat land, hills and slopes, and can be completed by the ground duty personnel. The continuous working time of each batch can reach 10-15 minutes, the single-day single-day working area is 300-500 mu, the spraying atomization degree is high, the drug utilization rate is increased by more than 40%, and the pesticide cost and labor cost are saved a lot. The goal of medicine.

The second measure: to achieve biological control

Biological control is the use of inter-relationships between biological species to inhibit one or another species of organism with one or a class of organisms. It can be roughly divided into three categories: insect control, insect control, and insect control. It is a method to reduce the population density of pests such as weeds and pests. It does not pollute the environment and is incomparable for non-biological methods such as pesticides.

Nowadays, drones have also become the carrier of biocontrol technology. Not long ago, Jinfengchun Aviation Technology Co., Ltd. of Shenyang held a new product launch conference, which developed a natural enemy insecticide delivery device with independent intellectual property rights on the drone, and applied a special container carrier to deliver eggs, larvae and adults for a variety of pests. It can achieve the effect of killing large areas, and it can effectively avoid the problems of pest resistance caused by chemical agents while carrying out disaster prevention and control. The carriers are all green degradable materials, which will die in the absence of food and will not cause secondary disasters.

Insect pest control, without pesticides, can naturally achieve the need to reduce drugs and increase efficiency.

The third measure: perfecting the rule of defense

At present, most of the farmers are decentralized to control pests and diseases, the degree of organization is low, the scale of prevention and control is small, and most farmers have no special training in the application of pest control in the field, and the phenomenon of improper drug use and excessive drug use is serious. A large number of traditional small sprayers are used in rural areas, which have low work efficiency and serious waste. It is urgent to use advanced medical equipment to improve the utilization rate of pesticides. At the same time, there are nearly 3,000 pesticide production enterprises and more than 300,000 pesticide distributors in the country, and most of these people have not been specially trained, and misleading drug use has occurred.

Professor Marx and Engels of Taiyuan Ecological Engineering School has been online for many years. He has kept in mind the actual situation of the place. He has been suffering from a heart disease for many years. He is about how to solve the problem of “unification and rule” and the emergence of plant protection drones. Let him see a new solution. According to Professor Ma, in the past, relying on the governance of one family could not effectively prevent pests and diseases. It is also very likely to delay the short-term good governance period, resulting in a large-scale epidemic. When plant protection drones are used in agriculture, they are using advanced Science and technology have achieved the goal of "unifying the rule of governance." In particular, it can be truly environmentally friendly by operating a drone flying defense team that provides scientific dispensing.

Of course, the current plant protection drones are not perfect for achieving “reduction of drugs and efficiency”, and there are parts that can be further improved. It is imperative to invent and improve the low-toxic and low-residue aviation pesticides that are compatible with drones. Secondly, we must also pay close attention to the research and development of nozzles that are more and less drifting pesticides, so that they can better realize the operation effect of drones. After that, it is necessary to "adapt to local conditions". China's topography and geomorphology are complex and varied. Many fruit trees are grown in different areas such as mountains, slopes and plateaus. Coupled with the different responses of the climate, it is necessary for drones to pay special attention to local cyclones during operation. Change the humidity and temperature difference, and change the working time and skills in time to further achieve “enhancement”.

According to the development requirements of the Ministry of Agriculture, China needs to accelerate the transformation of agricultural development methods, explore new models of low-carbon, environmental protection and sustainable development, improve agricultural production safety, agricultural product quality and safety, and ecological and environmental security, and achieve pesticide use by 2020. The goal of zero growth has new requirements for pest control.

Achieving "reduction and increase efficiency" of pesticides is undoubtedly an inevitable development trend. Utilize drones to achieve specialization and control, green prevention and control, and integrate environmental protection pesticides as the focus, aim at reducing pesticides and increasing efficiency, and innovate prevention and control methods and integrated prevention and control technologies. On the basis of pesticide reduction, Achieve steady income and increase income.

Shao Zhenrun, a plant protection expert from the National Agricultural Technology Extension Service Center, said in an interview that “pesticide reduction and efficiency increase and development of green ecological agriculture” is a key work of the Ministry of Agriculture this year. It is understood that this year the Ministry of Agriculture has formulated the principle of modern plant protection construction as the principle, and established thousands of acres of fertilizer and pesticide reduction demonstration zones in Jiangsu, Anhui and Shandong provinces.

Perhaps this year, we will see more examples of plant protection drones to help the development of green agriculture.
