近年来各地反映,麦田杂草逐年增多,由于恶化了小麦生长环境,对小麦产量的影响日趋严重。造成杂草增多的原因可能是:①灭草效果较好的传统的轮作和耕作法有所改变;②施用未经堆沤腐熟带有大量草籽的畜粪;③农技上还没有一套综合的灭草措施。针对上述情况,1982年我们设置试验,探索麦田自生杂草对小麦的为害和常规的人工、化学除草(下称化除)的灭草、增产效果,为改进麦田除草措施和进一步研究提供依据。
In recent years, it has been reported around the world that the weeds in the wheat fields have been increasing year by year. The worsening of the wheat growing environment has an increasingly serious impact on the yield of wheat. The reasons for the increase of weeds may include: ① the traditional crop rotation and tillage methods that have a good effect on weeding have changed; ② livestock dung with a large amount of grass seeds that has not been matured by pile hedges; ③ no set of agricultural techniques yet Integrated weed control measures. In response to the above situation, we set up a trial in 1982 to explore the wheat weeds self-infested weeds damage and conventional artificial, chemical weeding (hereinafter referred to as the “weeding”), the yield increase, to improve the weed control measures and further research provide the basis.
