摘　　要：为筛选适宜鲁西北地区大豆玉米带状复合种植条件下的除草剂,选用7种除草剂5种不同处理进行土壤封闭试验,对杂草株防效、鲜重防效和作物产量进行研究。结果表明,720 g/L异丙甲草胺+51%丙炔氟草胺、40%砜吡草唑+51%丙炔氟草胺2种处理的株防效均在87%以上,鲜重防效均在98%以上,对大豆和玉米安全,且能促进大豆增产43.38%以上,促进玉米增产21.76%以上,可以作为适宜鲁西北地区大豆玉米带状复合种植田的播后苗前封闭除草剂使用。In order to screen herbicides suitable for soybean-maize zonal compound planting in northwest Shandong Province,seven herbicides with five different treatments for soil closure test were selected,and the effect of weed plant control efficiency,fresh weight control efficiency and crop yield was studied.The results showed that the control effect of 720 g/L metolachlor+51%flumioxazin,40%pyroxasulfone+51%flumioxazin were above 87%,and the control effect of fresh weight were above 98%,which were safe to soybean and corn,and could promote the increase of soybean by more than 43.38%and corn by more than 21.76%.It can be used as a suitable herbicide treatment for post-seeding and pre-seeding of soybean and corn strip compound planting field in northwest Shandong Province.
