摘　　要：采用随机区组方法研究了免耕麦田杂草群落,结合除草剂的筛选,进一步探讨了其控制策略。结果表明,阔世玛与世玛能有效防治麦田杂草,尤其对禾本科杂草防效高;对阔叶杂草防效低于2,4-D丁酯与快灭灵;但对杂草总防效较高,分别达到90.8%、82.7%,并且对小麦株高、产量构成因素和籽粒产量无不良影响。The communities of weeds were studied by random block, and field trials for herbicide screening were further conducted to develop the control strategies. The result showed that sigma and sigma broad could efficiently control gramineous grass in wheat field, and the control effects were less than that of 2.4-D Butylate and carfentrazone-ethyl on broad - leaved weeds, but they had higher total control effects than the others, they were 90.8%,82.7% respectively, and they had no bad effects on the plant height, yield component factors and kernel yield.
