摘要
农药雾滴飘移是造成药液流失、环境污染、病害防治效果低的重要原因。非目标的雾滴飘失导致了水土污染,人畜中毒,环境恶化等大量问题。为了增强作物种植中施药喷雾对病虫害的防治效果,提高化学农药的使用效率,节省农民的种植成本,减轻农药对环境的污染和人员的伤害,针对喷雾过程中现存的大量问题,结合了目前国内农药的使用现状及相关飘移控制技术的发展,通过对辅助式喷雾、低量低压喷雾、变量喷雾、静电喷雾、抗飘移喷头和农药改善配方的使用等几个方面综述了目前防飘移技术的研究进展,并对其进行综合,提出了一种可行的缓解农药污染的防飘移方案。
Spray drift of pesticide is an important factor to cause pesticide loss ,environmental contaminations and low ef-fectiveness of pesticide application .Non-target droplet drift led to a large number of problems , such as the soil and water pollution , human and animal poisoning , and environmental degradation and so on .In order to improve the control effect of pesticide spray on agricultural crops diseases and insect pests , reduce the use of chemical pesticide , save farmers ' planting cost and mitigate the harm of pesticide pollution to the environment and personnel , in this paper , the problems existing in the process of pesticide spraying were taken into account;current situation of domestic pesticide use and de-velopment of the related drift control technology were combined , and then advanced to review several aspects of auxiliary spray technology , low levels and low pressure spraying , variable rate spraying technology , electrostatic spraying technique and the use of anti drift nozzles and the improving pesticide formulations in drift control technology .Finally put forward a comprehensive and workable anti-drift plan about relieving pesticide pollution .
