中文摘要：

病虫害是制约作物良好生长、粮食安全生产的重要因素之一.然而,在当前尚缺乏有效预警手段和物理防治方法的情况下,化学药剂防治仍然是防治病虫害的主要手段.为此,介绍了植保无人机相比传统地面施药的优势和特点,对国内外植保无人机的发展研究概况进行了梳理和总结,通过与发达国家精准施药技术的比较,分析了我国在施药关键技术和施药配套装备与技术方面的不足,并简要介绍了无人机振动源的研究现状,阐述了植保无人机未来的研究发展趋势,为后续的研究工作提供铺垫.同时,指出了无人机低空施药技术将会大幅提高病虫害防治效率,促进我国现代农业的发展.

英文摘要：

Plant diseases and insect pests is one of the important factors that restrict good crop growth and food safety in production.However, in the current situation that lack of effective early warming method and physical method of prevention and cure, chemical prevention and control is still the main method for the prevention and control of plant diseases and insect pests.This article described the advantages and characteristics of aerial spraying technology compared to conventional ground administer.In this article, the current status of plant protection unmanned aerial vehicle at home and broad were reviewed and summarized.Through comparing the current situation of accurate spraying technology with developed countries, the shortage of our country in key technologies of spraying and auxiliary equipment and technology used in spraying was analyzed.This paper briefly introduced the current research situation of unmanned aerial vehicle vibration source, and then the prospect of world＆#39;s agricultural aerial spraying was explained, laying a foundation for further research.At the same time pointed out that aerial spraying will significantly increase the efficiency of prevention and control of plant diseases and insect pests, promoting the development of modern agriculture in our country.
