| 摘 要： | 对农达和乙阿合剂单用及桶混在免耕玉米田的除草效果进行了研究，结果表明，免耕玉米田单用乙阿合剂，不能秀好防除已出土杂草，农达与乙阿合剂混用，由于农达到已出土杂草的触杀作用及乙阿合剂对未出土杂草的封闭作用，使免耕玉米田杂草得以很好控制，施用农达41％水剂2250mL/hm^2混用乙阿合剂40％悬乳剂2250mL/hm^2对供试玉米田杂草株数及鲜重防效可达90．3％和96．6％，与两药剂单用比较除草增产作用显著。

| Abstract: | Field experiments were conducted to evaluate preapplied roundup tank mixtures with atrazine plus acetochlar for weed control in zero-tillage corn field.Applying atrazine plus acetochlar alone provided relatively worse weed control.Roundup tank mixtures with atrazine plus acetochlar showed excellent weed control with the control efficiency of 90.3% for weed density and 96.6% for weed fresh weight.No crop damage was observed for each treatment. |
