Abstract: [Objective] The study aims to screen out the herbicide with good control effect on the weeds in the field and to provide scientific basis for the safe and efficient application of the herbicide.[Method]The method of randomized block experiment was used in field trial and the amount of broadleaf weeds and grass weeds were investigated.[Result]After 40 days, the result showed that the treatments of 10; monosulfuron WP with the dosage of 210 g a.i./hm2, 45; propazine-simetryn WP with the dosage of 1,181.25 g a.i./hm2 had better effect on grassy weeds and broadleaf weeds of summer millet, the control effect of plant number was above 86;, and the control effect of fresh weight was above 96;.48; dicamba AS with the dosage of 360 g a.i./hm2 had better effect on broadleaf weeds of summer millet, the control effect of plant number was 85.61;, and the control effect of fresh weight was 99.88;.[Conclusion]Two dilution method was used for field spraying, 10; monosulfuron WP, 45; propazine-simetryn WP and 48; dicamba AS were recommended for application in summer millet field in Southern Xinjiang.

摘要： [目的]筛选对复播谷子田杂草具有较好防效的除草剂,为安全、高效应用除草剂提供科学依据.[方法]采用随机区组的方法,定点取样调查各处理小区的杂草株数、鲜重,评价各供试药剂对杂草的防除效果.[结果]10;单嘧磺隆可湿性粉剂210 g a.i./hm2处理和45;扑津·西草净可湿性粉剂1 181.25 g a.i./hm2处理,对复播谷子田单子叶杂草和双子叶杂草的防效均在86;以上,鲜重防效均在96;以上;48;麦草畏水剂360 mL a.i./hm2处理,对复播谷子田双子叶杂草的防效为85.61;,鲜重防效为99.88;.[结论]选用10;单嘧磺隆可湿性粉剂、45;扑津·西草净可湿性粉剂和48;麦草畏水剂,采用二次稀释的方法进行田间喷雾,可有效防除南疆区域复播谷子田杂草.
