麦田化学除草虽然推广多年了,但各地应用效果却大不相同。有的杀灭杂草效率很高,有的并不理想。从现状看,在麦田化学除草上,还存在着四重四轻的问题,即重水地麦除草,轻旱地麦除草;重冬前除草,轻春季除草;重除草剂新品种,轻常规品种;重常规除草方法,轻灵活应变除草技术。因此,今年秋播麦田化学防草,应着力抓好提高防除效果。
Although the promotion of wheat field chemical weeding for many years, but the application effect is very different across. Some kill weeds high efficiency, and some are not ideal. Judging from the status quo, in the field of chemical weeding in the wheat field, there are still four quadruple light problems, namely, weeding in dry land and wheat in dryland and grassland; weeding in early winter and light spring weeding; heavy herbicide new varieties and light conventional varieties; Heavy weeding method, light flexible strain weeding technology. Therefore, this fall autumn wheatfield chemical prevention and control of grass should focus on improving prevention and control.
