夏玉米生长期正值高温、高湿季节,田间杂草生长量迅速.加之雨水较多人工及机械防除杂草比较困难等因素,夏玉米田化学除草越来越被农民接受和普遍应用。玉米除草剂品种繁多,使用技术要求高,使用不当会对玉米产生药害。以下六点是夏玉米田使用除草剂的注意事项:第一,收割完小麦后,如果地里已经有大量杂草,必须用“灭生性”除草剂。防治效果明显的有“克无踪”、“百草枯”和“草甘膦”。前两者属于“触杀”性灭草剂,能直接杀死所有接触到的绿色 Summer corn growing season is at high temperature, high humidity season, the rapid growth of weeds in the field, combined with more rain and artificial mechanical weed control more difficult factors such as summer maize chemical weeding more and more farmers accept and universal application. A wide range of corn herbicides, the use of high technical requirements, improper use of corn will have phytotoxicity. The following six points are the use of herbicides in summer corn fields: First, after harvesting wheat, weeds must be used if there is already a large amount of weeds in the field.
