近几年来,一些农民反映,大田除草剂的防除效果越来越差,一次性封闭除草剂很难达到理想效果,因此前后二次除草面积逐年增加。这不仅增加了生产成本,浪费了劳动力,还加大了对耕地和环境的污染。
In recent years, some farmers have reported that the effectiveness of field herbicides is getting worse and worse. One-time closed herbicides can hardly achieve the desired results. Therefore, the area of second herbicides increased year by year. This not only increased production costs, wasted labor, but also increased the pollution of cultivated land and the environment.
