[目的]为减少蚜虫对小麦的危害提供科学依据.[方法]设6个降水级别,即:小雨、中雨、大雨、暴雨、大暴雨、特大暴雨.在小麦的拔节期、抽穗扬花期、灌浆期分别进行雨水冲刷试验,研究不同级别的雨水冲刷对麦蚜与捕食性天敌数量的影响.[结果]在小麦的3个生长时期,雨水冲刷均对麦蚜与捕食性天敌的数量有一定影响.随着降雨强度的增加,麦蚜与捕食性天敌的冲刷率也随之呈上升趋势.特大暴雨时,麦蚜与捕食性天敌的冲刷率最大.[结论]中等以上雨量对麦蚜与捕食性天敌有较强的冲刷作用,雨量越大,冲刷率越大.

[Objective] The study aimed to provide scientific proof to reduce the aphids to harm wheat. [Method] The study set up 6 rainfall grades, i.e. light rain, moderate rain, rainstorm, heavy rainstorm, torrential rain. Rain wash test was respectively conduced in jointing stage, flowering stage, filling stage, the effects of rain wash on quantities of cereal aphides and predators. [Result] Rain wash had some influences on quantities of cereal aphides and predators in 3 growth stage of wheat. The scour rate showed rising trend with the increase of rainfall intensity. Scour rate reached the maximum in the torrential rain. [Conclusion] It had strong washing action on cereal aphides and predators above moderate rain, and the larger the rainfall, the greater the scour rate.
