摘　　要：[目的]探讨烟嘧磺隆、辛酰溴苯腈以适当配比复配对夏玉米田单双子叶杂草的防除效果,为玉米田杂草的防除提供参考.[方法]通过田间小区试验研究了不同剂量烟嘧·辛酰溴苯腈15％油悬浮剂对夏玉米田单子叶、双子叶杂草的防除效果.[结果]烟嘧·辛酰溴苯腈15％油悬浮剂在夏玉米田茎叶喷雾施药,对夏玉米田多种1年生单子叶、双子叶杂草的除草效果较好,杀草谱广,速效性好,持效期长.药后30 d株防效均在90％以上,鲜重防效均在95％以上,1 500～3 000 ml/hm2剂量对夏玉米安全.[结论]考虑到大田使用条件,推荐剂量为1 800～2 250 ml/hm2.[ Objective ] Control efficacy of 15% Nicosulfuron · Bromoxynil octanoyl against summer corn weeds was explored to provide reference for control of corn weeds. [ Method ] Control efficacy of 15% Nicosulfuron · Bromoxynil octanoyl against summer corn weeds was studied through plot test. [ Result ] The product had good effect to control a variety of annual monocots and dicot weeds in summer corn field, and it had wide control spectrum, rapid control effect, and long lasting effects. After 30 days of spraying, the preventing effect reached above 95% for each plant, and fresh weight control efficiency was above 95%. It was safe to summer corn at the dosage of 1 500 - 3 000 ml/hm2. [ Conclusion] Con- sidering field conditions, the recommended dosage is 1 800 -2 250 mL/hm2.
