摘　　要：[目的]探讨15％麦极和10％苯磺隆混用防治野燕麦、荠菜、小藜3种麦田主要杂草的效果。[方法]采用盆栽法。[结果]结果表明，15％麦极WP同10％苯磺隆适宜的混用组合能有效控制2～4叶期野燕麦，同时能有效控制荠菜、小藜2种阔叶杂草。其中，150g／hm^2 15％麦极＋150g／hm^2 10％苯磺隆和150g／hm^2 15％麦极＋300g／hm^2 10％苯磺隆2个组合，防治效果比单独使用明显提高。[结论]15％麦极同10％苯磺隆混用的最适宜的组合为150～300g／hm^2 15％麦极＋150g／hm^2 10％苯磺隆2，该组合对野燕麦、荠菜和小藜的防治效果均为100％。[Objective] The controlling effects of 15% clodinafop-propargyl mixing with 10% tribenuron against Avenafatua L. , Capsella bursa-pastoris （ L. ）. Medic. and Chenopodium serotinum which were the main weeds in wheat fields were discussed. [ Method ] Potted plant method was used. [ Result ] The results showed that Arena fatua L. and other 2 species of broad-weeds at 2 -4 leaf stages could be efficaciously controlled by spraying the mixture of 15% clodinafop-propargyl and 10% tribenuron mixture. The controlling effects of the treatments 5% clodinafop-propargyl 150 g/hm^2 mixing with 10% tribenuron 150 g/hm^2 and 15% clodinafop-propargyl 150 g/hm^2 mixing with 10% tribenuron 300 g/hm^2 were significantly higher than the treatment of 15% clodinafop-propargyl 150 g/hm^2. [ Conclusion] The most optimum mixing dosage of 15% clodinafop-propargyl and 10% tribenuron was 150 -300 g/hm^2 ＋ 150 g/hm^2 and their controlling effects were 100% against 3 weeds.
