摘　　要：为明确12%双氟磺草胺·唑草酮·氯氟吡氧乙酸悬浮剂在冬小麦田的应用前景,采用了田间小区试验的方法,研究其对冬小麦田主要阔叶杂草的控制作用和对小麦的安全性。结果表明:12%双氟·唑·氯氟吡氧乙酸悬浮剂对冬小麦田主要阔叶杂草猪殃殃、荠菜、播娘蒿、繁缕等阔叶杂草均有较好的防除效果,随用药量的增加防效逐渐提高,各处理药后30 d株数防效和鲜质量防效均在95%以上,优于苯磺隆常规剂量处理的防效,对小麦安全性良好,提高了小麦的产量。A field experiment was carried out to study the efficacy of florasulamocarfentrazone-ethylofluroxypyr 12%SC ( FCF) on broadleaf weeds and its selectivity in winter wheat fields.FCF provided excellent control of Descurainia sophi-a,Capsella bursa-pastoris,Galium aparine and Stellaria media,Control gradually improved with dose increments.At 30 days after application,weed density and fresh weight reductions were still greater than 95%,which were better than those achieved wit tribenuron-methyl at the recommended dose,with a concomitant crop yield increase.
