农作物病虫草害防治是农业生产中一个必不可少的环节,作业机具、农药制剂、施药技术3个方面对农药利用率和病虫害的防治效果有着重要影响,不仅体现重大病虫防控能力和效率以及成本,还关乎农产品质量安全和农业生态安全。虽然我国农药生产技术已处于世界先进水平,但施药机具和技术水平却严重滞后,不仅农药利用率低、施药效果差,还造成农产品中农药残留超标、环境污染、作物药害和操作者中
Crop pest and weed control is an indispensable link in agricultural production. Work implement, pesticide preparation and pesticide application have an important influence on pesticide utilization and pest control. They not only reflect major pest control and prevention and control Efficiency and cost, also related to the quality and safety of agricultural products and agricultural ecological security. Although pesticide production technology in China is already at the advanced level in the world, the level of pesticide application equipment and technology has lagged behind. Not only the pesticide utilization rate is low, but the pesticide application effect is poor, and pesticide residues in agricultural products exceed the standard, causing environmental pollution, crop injury and operators in
