摘　　要：长残留除草剂在我国使用面积迅速扩大，造成后茬作物受害事件时有发生，已成为一个不容忽视的问题。大多数长残留除草剂品种在土壤中的降解和残留与温度、降雨、土壤特性，特别是土壤ｐＨ密切相关，根据这些特点，采用正确的使用技术，是可以缓解与消除它们对后茬作物的伤害的。The application area of long residue herbicides expands rapidly in our country,and make it a serious problem about the carryover to the subsequent crops.The fate of most of long residue herbicides is closely related to temperature,rainfall,and soil characteristics,especially to soil pH.According to these feature,adopting proper application technology in practice can reduce,or even eliminate the residue injure to subsequent crops.
