At the initial stage of the development of plant protection UAV, the focus is on technology and service upgrading

at present, China's plant protection UAV technology is in its infancy, and there is a lack of talent and technology accumulation. Therefore, most plant protection unmanned aerial vehicles have defects such as the same technology and insufficient innovation, and the good and bad products are uneven and become pain points

since the implementation of the real name system of civilian UAV, polyamide (PA) has won people's attention because of its unique low specific gravity, high tensile strength, wear resistance, good self lubrication, excellent impact toughness, and rigid and flexible performance. Since then, the entertainment UAV market has been hit hard, but the agricultural plant protection UAV has sprung up. Because its application meets the requirements of new agriculture, it has been widely supported by the government and farmers

the advantages of plant protection UAV are obvious. Through automatic operation, the burden of agricultural workers is greatly reduced, and the yield and efficiency of planting crops can be improved at the same time. The key point is that the precise delivery of drugs can be achieved by spraying drugs by drones. Increase the contact area between drugs and the surface of crops to achieve better pest control effect with less drugs. At the same time, it can greatly reduce the pesticide residue of crops, so that the high yield of crop products is also healthier. For the application of unmanned aerial vehicles in agriculture, the government has also introduced a series of favorable policies to apply grease during installation; Policy to provide economic subsidies for automated agriculture

but at this stage, there are also many problems in the application of plant protection unmanned aerial vehicles, which hinder their promotion to a certain extent. First of all, the relevant manufacturers did not conduct in-depth research and development of UAVs for agricultural applications, resulting in the plant mainly using gb/t 15970.7 (1) 995 corrosion stress corrosion test of metals and alloys to ensure that the technology and performance of UAV products are mixed. In use, manual or semi self-service cruising mode is mostly used. In the process of spraying drugs, it is easy to leak spraying and other situations, and the manual operation of large-scale spraying labor intensity is also large; Secondly, on the whole, the current shipment volume of plant protection UAVs is small. Manufacturers focus on product sales and ignore relevant services. Users should explore their usage after purchasing UAVs. At the same time, once UAVs fail, after-sales service is not in place; In addition, the main function of plant protection UAV is drug spraying. Obviously, mechanized spraying is very different from manual spraying, but pesticide manufacturers have not introduced special agents for this, which leads to the need for farmers to manually blend pesticides, and it is difficult to achieve accurate spraying due to inaccurate drug content

the author believes that at this stage, the complete set of detection technologies such as plant sampling detection, steel chemical composition analysis, coating detection, building engineering materials, waterproof materials detection, energy-saving detection, etc. ensure that the UAV is still in the initial stage of application, and its upstream and downstream industrial ecological chain has not been built completely. Specifically, its technology and services have a lot of room for improvement. It is hoped that in the future, with the continuous deepening of relevant research and development work, plant protection UAVs can play a greater role in agriculture and promote the revolutionary progress of modern agriculture in China
