摘　　要：我国常年遭受严重草害的麦田面积有0.4亿亩,造成产量损失约30%,运用化学除草剂防除麦田杂草已经成为小麦生产中的重要手段,形成了包括多种作用类别的除草剂品种和全方位化学防除体系。但随着化学除草剂的不断推广和应用,杂草抗药性问题也日益凸显和加重,目前播娘蒿、日本看麦娘、菵草等杂草抗药性已经较为严重。通过查阅相关文献,综述了近几年我国小麦田的优势杂草种类,主要应用的除草剂以及麦田杂草的抗药性现状及防治对策。About 40 million hectares of wheat fields are heavily infested by weeds and the annual reduction of crop yields is 30% （weighted average） in China. Chemical weed control has changed cultural practices to save weeding labor in wheat. At the same time, continuous use of the same herbicides has caused weed shift problems and weed resistance to herbicides. Resistant biotypes of Descuminia sophia, Alopecurus japonicus and Beckmannia syzigachne were reported in recent years. The main worst weed species, application status of herbicides and herbicide-resistant weeds in wheat fields of China were introduced in this paper, and integrated management strategies for resistant weeds were also described.
