摘　　要：采用室内生物测定方法,研究硝磺草酮与二氯吡啶酸复配联合作用类型,对复配制剂进行田间效果试验。结果表明,硝磺草酮对马唐、稗草效果较好,对马齿苋、铁苋菜效果差;二氯吡啶酸对马齿苋、铁苋菜效果较好,对马唐、稗草近无效。两者复配后优势互补,作用类型均为相加作用。硝磺草酮与二氯吡啶酸两者混配剂可作为备选药剂进行田间试验,茎叶处理防除玉米田杂草,推荐比例为0.67-2.67∶1。田间试验结果表明,硝磺草酮与二氯吡啶酸复配后综合两种单剂优势,对试验田杂草马唐、马齿苋、铁苋菜和苘麻均有很好效果。Weed control efficacy of mesotrione ＋ clopyralid were evaluated in greenhouse and field. The result showed that mesotrione and clopyralid were complementary to 4 kinds of weeds, mesotrione was better to control D. sanguinalis and E.crusgalli, but worse to A.hispida and P.oleracea, and the opposite result was gotten in clopyralid. Mesotrione ＋ clopyralid was additive in controlling 4 kinds of weeds. It was illustrated that mesotrione ＋ clopyralid could be applied on controlling the weeds in maize fields, and the optimum mixing proportion was 0.66-2.67 ： 1. The conclusion showed that, mesotrione ＋ clopyralid had good effects on D.sanguinalis, A.hispida, P.oleracea and A. theo- phrasti, and safety to maize.
