摘　　要：为筛选出防效好、安全性高的大豆玉米带状复合种植除草方案,本研究探索了不灭茬和旋耕灭茬两种种植模式下不同类型的除草剂的株防效和鲜重防效。结果表明:旋耕灭茬田和不灭茬田两种模式中,均是土壤封闭+茎叶喷雾除草株防效和鲜重防效最好,其次是仅开展土壤封闭除草,仅开展茎叶喷雾除草防效最低。旋耕灭茬模式下土壤封闭+茎叶喷雾、仅土壤封闭、仅茎叶喷雾除草各处理区株防效分别为76.43%~88.59%、72.24%~77.62%、53.23%~61.98%;鲜重防效分别为87.95%~97.05%、82.28%~89.51%、64.61%~68.54%。不灭茬模式下土壤封闭+茎叶喷雾、仅土壤封闭、仅茎叶喷雾除草各处理区株防效分别为72.58%~88.31%、64.92%~72.18%、53.63%~54.84%,鲜重防效分别为82.08%~98.37%、72.11%~82.94%、52.13%~59.57%。此次试验筛选了不同种植模式下的除草剂种类,为解决带状复合种植模式下的除草难题提供理论支撑。In order to screen out effective and safe weed control schemes for soybean and corn belt composite planting,the control effects of different types of herbicides under two kinds of planting modes were evaluated.The results indicated that in the two models soil sealing and leaf spray had the best effect on weed control and fresh weight control,followed by soil sealing only,and stem and leaf spray was the worst.The plant control effects of soil sealing and leaf spray,soil sealing only,stem and leaf spray only under the rotary tillage stubble removal mode were 76.43%-88.59%,72.24%-77.62%,53.23%-61.98%;the fresh weight prevention effects were 87.95%-97.05%,82.28%-89.51%,64.61%-68.54%.The plant control effects of soil sealing+stem and leaf spray,soil sealing only,stem and leaf spray only in the non stubble cutting mode were 72.58%-88.31%,64.92%-72.18%,53.63%-54.84%,the fresh weight prevention effects were 82.08%-98.37%,72.11%-82.94%,52.13%-59.57%.This experiment screened the types of herbicides under different planting modes,providing theoretical support for solving the problem of weed control under the strip composite planting mode.
