近些年来,随着耕作制度的调整,施肥水平的提高,农作物草害日趋严重。加上大批劳力外流打工,还有部分劳力从种植业向工副业转移,农田草害和劳力不足的矛盾日趋严重。为了减轻农民劳动强度,提高劳动生产率,我们在筛选对口、高效、低毒除草剂方面作了大量工作,并在大面积推广应用。据统计,1993年,全区推广化学除草面积达到30万hm~2,其中,推广10％灭草王防治稻田杂草面积为3.33万hm~2,且效果很好。据黄梅县植保站于1993年在中稻田试验调查(6月12日施药),每666.7m~2稻田用
In recent years, with the adjustment of farming system and the improvement of fertilization level, the crop damage has become increasingly serious. In addition, a large number of laborers migrate to work outside their home. Some of the labor force has also been diverted from planting businesses to sideline and sideline occupations. The contradiction between farmland infield and labor shortage has become increasingly serious. In order to reduce the labor intensity of farmers and improve labor productivity, we have done a lot of work in screening counterparts, efficient and low-toxicity herbicides and have been widely applied. According to statistics, in 1993, the area of promoting chemical weed control reached 300,000 hm ~ 2. Among them, the promotion of 10% Ophiopogon japonicus to control weed area in paddy fields was 33300 hm ~ 2, and the effect was very good. According to Huangmei Plant Protection Station in the mid-paddy field in 1993, the survey (June 12 application), every 666.7m ~ 2 paddy field
