摘要: 为探讨大豆玉米带状复合种植杂草防除技术,本研究采用播后至苗前的土壤封闭方法,对6种除草剂进行了田间药效试验.结果表明,40%扑·乙可湿性粉剂、 20%氟草·草铵膦可分散油悬浮剂土壤封闭处理对阔叶杂草防效较好,药后30 d对阔叶类杂草株防效分别为99.31%, 96.76%,鲜质量防效分别为99.97%, 99.42%;对水苋菜株防效分别为99.31%, 96.99%,鲜质量防效依次为99.97%, 99.30%.药剂处理均对大豆和玉米安全,未发现药害.

Abstract: In order to seek weed control technology in soybean corn compound planting field, 6 kinds of herbicides were applied in soil sealing test at seedling stage after sowing. The results showed that 40% promethazine·acetonide wettable powder and 20% Flufop·Glyphosate dispersible oil suspension agent had a good control effect on broadleaf weeds. On the 30 th day after application, the control effects on broadleaf weeds were 99.31% and 96.76%, and the control effect ofthe fresh mass were 99.97% and 99.42%, respectively. Besides, the plant control effects on Ammannia baccifera. were 99.31% and 96.99%, control effect of the fresh mass were 99.97% and 99.30%, respectively. Each agent used in the treatment was safe for soybean and corn.-
