【Abstract】 Weeds control was a very important problem in the soybean intensive production. In the soybean field, the herbicides should be used for weeds control on the basis of killing the weeds by hand or by machine, but we should care the effect of herbicides on biological environment such as low residues. The herbicides were used to control the weeds, which would increase the efficiency of production, decrease the labor and production cost, and then make a better competition of soybeans in the worldwide market.更多还原
