在菜豆种植上农民常采用播前浇足底水,播后苗前不浇水的办法以防烂籽,并使豆苗植株健壮。因此土表较干燥,采用播后苗前施用的土壤处理型除草剂如氟乐灵、除草醚等有时除草效果不够理想。近年来已发展了一些用于豆科作物杂草上茎叶处理型除草剂如磺氟草醚、苯达松、拿捕净、盖草能等。通过混用的办法可以对架豆苗后作茎叶处理,对单双子叶杂草达到十分理想的防治效果。本试验对防治阔叶草的磺氟草醚和苯达松、防治禾本科草的拿捕净、盖草能进行 Peasants in the cultivation of beans often used before sowing the water at the end of sowing, after sowing seedlings not watering the way to prevent rotten seeds, bean plants and make robust. Therefore, the earth’s surface is drier and the weeding effect is not ideal when the soil-treated herbicides such as trifluralin and weedicide applied after sowing before sowing. In recent years, some of the herbicides used in leguminous crops such as sulfonylurea, bentazon, bentonite, cap grass and the like have been developed. Through the mixed approach can be made after the stems and leaves of bean sprouts treatment, the dicotyledonous weeds to achieve a very good control effect. This test on the prevention and control of broad-leaved grass sulfflorfen and bentazon, grass control net grazing, cover grass can be carried out
