中文摘要:为明确双氟磺草胺、2甲4氯复配的联合作用类型及在小麦田应用的可行性，采用温室盆栽生物测定法和田间药效试验，研究了二者对播娘蒿、猪殃殃等的联合毒力、田间除草效果及其对当茬小麦和后茬作物的安全性。结果显示，双氟磺草胺、2甲4氯复配对播娘蒿为增效作用，对猪殃殃为相加或增效作用，二者适宜配比为1：100~120。43%双氟磺草胺·2甲4氯SE（混配比例为1：110） 387、516、645和1 032 g/hm²防除小麦田阔叶杂草效果均较好，秋季施药鲜重防除效果为99%以上，春季为95%以上。43%双氟磺草胺·2甲4氯SE对当茬作物小麦和后茬作物玉米、大豆、花生、棉花出苗和生长均无影响。

Abstract:Dose-response experiments were conducted to determine the combination type of florasulam+MCPA by calculating the co-toxicity coefficients in greenhouse. Weed control effect, response of winter wheat and rotational crops to different dosages of 43% florasulam+MCPA SE were also investigated in fields in Jinan, Shandong Province. The results showed that the ratio of 1:100-120 was the best that exhibited a synergistic effect on control of the grasses, Descurainia sophia and Galium aparine. The 43% florasulam+MCPA SE achieved high weed control when applied at 387, 516, 645 and 1 032 g/hm² during spring and autumn in winter wheat. Fresh weights were reduced by more than 99% when applied in autumn, and more than 95% in spring. The 43% florasulam+MCPA SE didn't cause injury to wheat and rotational crops, including maize, soybean, peanut and cotton.
