我市种植业以种植大豆为主,其种植面积占总种植面积的80%以上。大豆田除草以化学除草为主,其中施用苗后除草剂作为防除大豆田杂草的主要措施,尤其是在春季土壤水分较大,机车难以作业,土壤处理面积相对少的情况下,其应用面积大幅度上升,但由于不良的气象条件和不当的使用技术等因素,会造成大豆药害的发生。 The planting industry in our city mainly grows soybeans, and its planting area accounts for more than 80% of the total planted area. The weed control in soybean field is dominated by chemical weed control. The application of post-emergence herbicide as the main measure to control weeds in soybean field especially in the spring when the soil moisture is large, the locomotive is hard to operate and the soil processing area is relatively small, Rise, but because of bad weather conditions and improper use of technology and other factors, will cause the occurrence of soybean phytotoxicity.
