| 摘 要： | 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%。

| Abstract: | 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/hm2was better than other herbicides.The plant control effects were 92.89% and90.99% 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%. |
