摘　　要：作为世界农业大国,我国每年要使用大量的农药用于防治农作物的病、虫、草害。近年来,由于受生态环境恶化、全球气候异常等因素的影响,我国农作物病、虫、草害发生的面积不断扩大,年商品农药用量80万t,年化学防治面积2亿hm2次以上。如何合理、科学地使用这些农药,以确保环境安全、人身安全和食品安全,施药器械和施药技术起着至关重要的作用。为此,论述了中小型植保药械的发展现状、亟待解决的问题以及施药技术和方法。The great amount of fertilizer is used in preventing plant diseases and insect pests in our country. During recent years, influenced by environment worsen, global weather abnormity and so on, the acreage of agricultural plant diseases and insect pests is greatly enlarged in our country. The quantity of market fertilizer is 800 thousand tons per year, and the area of chemical prevention is more than 2 hundred million hm2 per year. Used these fertilizers reasonably and scientifically to ensure environmental safety, person safety and food safety, fertilizer machinery and fertilizer technology play an important role. So expounded the present status, problems, fertilizer technology and method of middle and small fertilizer machinery for plant protection.
