摘　　要：为了筛选适合大豆—玉米带状复合种植模式的除草剂和施用方法,本试验选用7种除草剂及复配剂进行土壤封闭处理和苗后处理,并对各处理的杂草防控效果、玉米、大豆产量和经济效益进行比较分析。结果表明,芽前封闭除草处理中,960 g/L精异丙甲草胺EC+75%噻吩磺隆复配剂的处理杂草防控效果较好,其药后40 d的杂草株防效为73.42%;采用芽前除草+苗后除草相结合的处理方法,药后40 d的杂草株防效为75.42%;施用除草剂能明显提高大豆、玉米产量,与不施除草剂的对照相比,增产幅度分别为22.6%~41.3%和15.2%~43.0%,可增加纯收入3600.8~8123.3元/hm^(2)。In order to select herbicides and application methods suitable for soybean-corn banded compound planting pattern,seven kinds of herbicides and mixtures were selected for soil closure treatment and post-seedling treatment.The weed control effects,corn and soybean yield and economic benefits of each treatment were compared and analyzed.The results showed that in the pre-bud herbicidal treatment,the weed control effect of 960 g/L Metolachlor-EC+75%-thiophenesulfuron compound was better,and the weed control effect of 40 days after treatment was 73.42%.The weed control effect of the combination of pre-bud weeding and post-seedling weeding was 75.42%.The application of herbicides can significantly increase the yield of soybean and corn.Compared with the control without herbicides,the increase in yield is between 22.6% to 41.3% and 15.2% to 43.0% respectively,and the net income can be increased by 3 600.8 to 8 123.3 yuan/hm^(2).
