What breakthroughs have been made in the plant protection UAVs?
On November 23, the 34th Accurate Plant Protection Summit Forum OF China Plant Protection Information Exchange & Pesticide Sprayer Facilities Fair was held in Chengdu. Wei Qiwen, Secretary of the National Agricultural Technology Extension Service Center, Guo Yongwang, deputy director, and Zhao Qing, researcher of the Pharmaceutical Devices Department, He Xiongkui, Yuan Huizhu and Qin Weicai, well-known experts and scholars engaged in flight control technology and pharmaceuticals research in China, and Meng Yanhua, National Aviation Plant Protection Science and Technology Innovation Alliance, attended the summit forum. Leaders of Heilongjiang, Jilin and Henan plant protection stations also attended the summit forum.​
 
 
As the first co-sponsor, Dajiang Agriculture also participated in the summit forum. In addition to handing in an excellent response sheet on the effect of plant protection and flight prevention, it also released a video of the announcement of new products in 2019.

In recent years, in addition to the recognition of more and more farmers, UAV-based flight control and plant protection services have been highly effective in the use of pesticides and the control effect of pests and diseases has also been recognized by experts and scholars after testing. At this precise plant protection summit forum, a number of experts and scholars have issued the flight control effect test report based on plant protection UAV.
Mr.Wei Qiwen Secretary of National Agricultural Technology Center
 
In his speech, Mr.Wei Qiwen mentioned that this precise plant protection Summit Forum is the finale of the Plant Protection Fair. It brings together experts, scholars and entrepreneurs from all walks of life in China. I hope this forum can provide technical support for the intelligent and informatization of precise plant protection and precise pesticide application in China. At the same time, it also adds a fire to the plant protection cause by intellectualization and informationization. In 2018, the number of plant protection UAVs in China exceeded 30,000, with an area of 267 million mu. Plant protection UAVs have been widely used in China.
 
Mr. He Xiongkui, Director of Center for Pharmaceutical Devices and Pesticide Application Technology, China Agricultural University
 
Mr. He Xiongkui said that the development prospect of precision standardization operation is good, and it is the only way to use pesticides safely and efficiently. Product quality, key working parts, operation quality and reliability are the connotations of precision pesticide technology and equipment. The improvement of pesticide droplet deposition efficiency is the goal. Intelligent precision variable spray technology requires large-scale field test production verification, and further improves the level of simplification and practicality of technical products.
Mr.Yuan Huizhu, Researcher in Institute of Plant Protection, Chinese Academy of Agricultural Sciences
 
At the meeting, Mr.Yuan Huizhu said that the control effect and efficiency of traditional pesticide spraying technology were not satisfactory. In the context of higher and higher labor costs, the new era needs efficient and safe plant protection equipment. Tests on wheat and peanut with MG-1P showed that the control effect of MG-1P was very good. For example, the control rate of wheat sprayed 7 days after spraying can reach more than 85%, and 97% - 98% after adding additives.
 
Meng Yanhua, Secretary-General of National Aviation Plant Protection Science and Technology Innovation Alliance
 
Meng Yanhua, secretary-general of the National Aviation Plant Protection Science and Technology Innovation Alliance, said that in 2018, our joint experimental tests in six provinces showed that the performance of plant protection UAV was stable as a kind of high-efficiency medicine, and it had obvious advantages in saving labor, water, improving pesticide utilization rate and reducing human poisoning. It was in the process of plant protection disaster prevention and mitigation in China. It plays an important role. Technological companies such as Dajiang have entered the field of plant protection UAV and continuously invested in R&D, which has greatly promoted the development of the industry.
