摘　　要：研究了不同兑水量情况下 ,除草剂在免耕麦茬土壤表面和麦茬上的沉积规律。实验结果表明 ,在无麦茬的情况下 ,增加除草剂兑水量 ,并不能提高除草剂在地面分布的均匀性 ;而在有麦茬条件下 ,增加兑水量可提高除草剂在地面分布的均匀性 。The study of herbicide deposition on soil surface and wheat stubble in different wheat mulch conditions is conducted. The experiment showed that the uniform distribution of herbicide deposition in free stubble environments can not be increased when water volume is increased. But the herbicide distribution uniformity can be increased when increasing water volume in wheat stubble environments. The herbicide deposition on wheat stubble can be decreased in high water volume.
