中国农用植保无人机施药技术研究概况

小型无人飞机作为新型农用植保机械凭借着相较于传统背负式施药机械的高效率、轻简化的农药施用技术,近年来发展迅速,针对植保无人机的研发与应用也日益增加。植保无人机施药是一种低容量高浓度的低空施药方式,其具有作业效率高、对人体危害小、适应性广、不受地形限制等特点,但低容量高浓度的施药方式不仅需要对农药的浓度有精准把握,同时施药技术、农药剂型的不同也会制约防治效果,本文旨在通过对植保无人机专用药剂及施药技术的研究与发展现状进行剖析,以期对植保无人机的未来研究与应用提供参考。

General situation of Research on Pesticide Application Technology of Agricultural Plant Protection UAV in China

As a new type of agricultural plant protection machinery, small unmanned aerial vehicle (UAV) has developed rapidly in recent years because of its high efficiency, light and simplified pesticide application technology compared with the traditional knapsack pesticide application machine, and the research and application of plant protection UAV is also increasing. Plant protection UAV pesticide application is a low-altitude pesticide application method with low capacity and high concentration, which has the characteristics of high working efficiency, little harm to human body, wide adaptability and not restricted by topography. However, the application mode of low capacity and high concentration not only needs to have an accurate grasp of the concentration of pesticides, but also restricts the control effect due to different application techniques and pesticide forms. The purpose of this paper is to analyze the research and development status of special agents and pesticide application technology for plant protection UAV, in order to provide reference for the future research and application of plant protection UAV.
