摘　　要：[目的]提高小麦产量。[方法]在冬小麦田间设置随机区组试验,测定不同浓度3.6%阔世玛水分散粒剂对野燕麦、猪殃殃、荠菜、野油菜的防除效果和对小麦的药害情况。[结果]3.6%阔世玛水分散粒剂300ml/hm2+拌宝1200ml/hm2和阔世玛3.6%水分散粒剂375ml/hm2+拌宝1500ml/hm2对野燕麦和阔叶杂草(猪殃殃、荠菜、野油菜)的株防效和鲜草减退率均在90%以上,具有很好的综合防效,且对小麦的药害较轻。[结论]冬小麦田间杂草的防除以阔世玛3.6%水分散粒剂300～375ml/hm2+拌宝1200～1500ml/hm2为宜。[Objective] The study aimed to enhance the yield of wheat.[Method] The control effect of different doses Sigma Broad 3.6% WG on Avena fatua L.,cleavers,shepherd′s-purse and Brassica campestris L.and its safety on wheat were determined by randomized blocks in winter wheat field.[Result] Sigma Broad 3.6% WG 300 ml/hm^2＋Biopower 1 200 ml/hm^2 and Sigma Broad 3.6% WG 375 ml/hm^2＋Biopower 1 500 ml/hm^2 had excellent total control effect on oat grass （cleavers,shepherd′s-purse and Brassica campestris L.）,and their control effect were over 90%,and had the slight phytotoxicity.[Conclusion] The best dosage was Sigma Broad 3.6% WG 300-375 ml/hm^2＋Biopower 1 200-1 500 ml/hm^2.
