我国历年水稻田病虫草害防治面积占全部的34%,占总防治量的三分之一。长期以来,水稻病虫草害防治主要依靠人力使用手动喷雾器和背负式机动喷雾机等常规植保机械进行,劳动强度大,作业质量差,作业效率低,已成为制约水稻全程机械化的主要技术瓶颈。2014年中央一号文件将“加强农用航空建设”列为“推进农业科技创新”的 Over the past years, the control area of ​​pests, diseases and weeds in paddy fields in China has accounted for 34% of the total, accounting for one third of the total amount of control. For a long time, the prevention and control of pests, diseases and insect pests in rice mainly relies on human hand using conventional sprayer and knapsack sprayer and other conventional plant protection machinery. The labor intensity, poor work quality and low work efficiency have become the main technical bottleneck restricting the mechanization of rice. In 2014, Central Document No. 1 lists “Strengthening Agricultural Aviation Construction” as “Promoting Agricultural Scientific and Technological Innovation”
