近几年由于小麦价格提升较快,棉花比较效益下降,不少两熟棉区小麦多改为满幅播种,播种量相应加大,加之农村劳动力结构弱化,清除麦田杂草的任务随之增大。同时,也由于近些年小麦除草剂的逐渐应用,有些杂草的抗药性相应增强,增加了防治杂草的难度。近期,有些农民朋友询问,因为季节紧张没来得及施用除草剂,小麦出苗后可补选哪些除草剂辅助除草?总结各地小麦田化学除草的经验,应区别
In recent years, due to the rapid price increase of wheat and the decrease in the comparative benefits of cotton, many double-cropped cotton fields changed to full-scale sowing with a corresponding increase in seeding rate. Coupled with the weakening of rural labor force structure, the task of clearing weeds in wheat fields increased Big. At the same time, due to the gradual application of wheat herbicides in recent years, the resistance of some weeds is correspondingly increased, which makes it more difficult to control weeds. Recently, some farmers’ friends asked about the herbicide that can be replaced after the emergence of wheat because of the season’s stress. After summarizing the experience of chemical weed control in wheat fields, we should distinguish
