Abstract: The amount of pesticide migrate was mainly influenced by the rainfall and its interval.Loss of the pesticides such as chlorpyrifos, cypermethrin and chlorothalonil transfer with runoff water ranged from 0.014 kg/hm² to 0.490 kg/hm², and the loss rates of the pesticides ranged from 9.79% to 20.51%.If it rain in 3 days after treatment, loss rates of chlorpyrifos and cypermethrin should be 8.32% and 5.58%, respectively, and the rates reduced with 50%.The migration of pesticides with runoff water would reduce and be help to reduce environmental pollution if the application time was adjusted based on rainfall forecast.

摘要： 农药化合物随地表径流迁移的损失量与降雨量和降雨间隔期有关。施药后当天降雨,毒死蜱、氯氰菊酯、百菌清随地表径流迁移量为0.014~0.490 kg/hm²,径流迁移损失率9.79%~20.51%;施药后3 d模拟降雨,毒死蜱、氯氰菊酯的径流迁移损失率分别为8.32%和5.58%,减少了50%以上。因此,根据天气降雨状况,调整施药时间,可减少农药随地表径流的迁移,有利于减轻对水环境的污染。
