在麦田化学除草剂的实际应用中,由于杂草种类繁多,单用一种除草剂往往难以达到理想的防除效果,而盲目加大用药量则产生药害,造成减产。为此,1994～1997年我们先后对几种麦田除草剂进行了混用试验。 几年来的推广应用证明, 2种除草剂混用的综合防效可达95%以上,比单用某一除草剂的防效能提高 In the practical application of chemical herbicide in wheat field, due to the wide variety of weeds, single herbicide is often difficult to achieve the desired effect of prevention and control, but blindly increase the amount of drug is produced injury, resulting in reduced production. For this reason, from 1994 to 1997, we conducted mixed experiments on several wheat field herbicides. Popularization and application over the past few years proved that the combined control effect of the two herbicides was over 95%, which was higher than that of a single herbicide alone
