在小麦生产中,大多数农民习惯在春季使用麦田除草剂,这时候草龄过大,杂草根壮叶厚、抗药性增强,再者麦田郁闭度增大,喷施除草剂量大,既费工又费钱,防除效果不理想,而且容易对后茬作物(如花生和棉花)造成药害。 In wheat production, most farmers are accustomed to using wheat field herbicides in spring. At this time, the grass age is too large, the thick roots of weeds grow thicker, and the drug resistance is enhanced. In addition, the canopy density of wheat fields is increased and the amount of herbicide sprayed is large. Costly and costly, the control effect is not ideal, but also easy to the stubble crop (such as peanut and cotton) cause injury.
