为了明确3种除草剂对全膜双垄沟播玉米田杂草的防治效果，采用随机区组法开展了田间小区药剂试验。结果表明：40%氰津·乙草胺悬浮剂3450 mL/hm2防效好，玉米出苗后30 d和45 d的株防效分别为92.89%和90.99%，出苗后45 d鲜重防效为90.39%，对玉米安全，无药害发生，玉米产量为9826.5 kg/hm2，较对照增产28.23%。50%利谷隆可湿性粉剂防效最好，但处理区有药害发生，减产率为50.72%～63.16%。
為瞭明確3種除草劑對全膜雙壟溝播玉米田雜草的防治效果，採用隨機區組法開展瞭田間小區藥劑試驗。結果錶明：40%氰津·乙草胺懸浮劑3450 mL/hm2防效好，玉米齣苗後30 d和45 d的株防效分彆為92.89%和90.99%，齣苗後45 d鮮重防效為90.39%，對玉米安全，無藥害髮生，玉米產量為9826.5 kg/hm2，較對照增產28.23%。50%利穀隆可濕性粉劑防效最好，但處理區有藥害髮生，減產率為50.72%～63.16%。

In order to define the weed control effect of 3 kinds of herbicides in whole film double furrow sowing corn field, field trials were carried out by randomized block method. The results showed that the control effect of cyanazine+acetochlor 40% SC at 3 450 mL/hm2 was better than other herbicides. The plant control effects were 92.89% and 90.99% on the 30th and 45th days after emergence, the fresh weight control effect was 90.39% on the 45th day after emergence. And it was safe to corn growth with the increasing rate of 28.23%. The control effect of linuron 50%WP was the best, but phytotoxicit occurred with decreasing rates of 50.72%-63.16%.
