摘　　要：除草剂的药效受到多种因素的影响,其中作为溶剂水的质量就是一要素,如硬水中钙、镁等金属阳离子,而含有锰、锌等金属阳离子的叶肥也会有影响,它们会对一些除草剂的防效有一定的减弱作用。硫酸铵是传统化肥,它可以增加一些除草剂的防除效果,而且可以减弱金属阳离子和锰、锌叶肥对除草剂除草活性的拮抗作用。The efficacy of herbicides are influenced by many factors, of which the quality of the solvent water is important one, suchas the content of metal cation Ca^2＋ and Mg^2＋ , and foliar fertilizer containing metal cation as zinc fertilizer and manganese fertilizer has action. Those metal cation can reduce the efficacy of some herbicides for controlling certain weeds. Ammonium sulfate is a traditional fertilizer, and also can increase the control effect of herbicides and reduce the antigonism of metal cation on the herbicides.
