摘要
研究了北京地区不同化学除草方式:播前土壤处理,播后苗前1处理、播后苗前2、出苗后处理和播后苗前2+苗期5种主要除草方式对夏播大豆田间杂草的防除效果。结果表明:(1)播后苗前+苗期茎叶处理方案对单子叶杂草除草效果最好;(2)播后苗前2处理对双子叶杂草防除效果明显;(3)对于杂草茎叶防治效果,播后苗前2+苗期处理有较显著防效。
Several of plans for weed control with herbicide were conducted in summer soybean field.The results showed that(1) the herbicides used at pre-emerge + post-emerge was better to control endogen weed;(2) post-emergeⅡ was better to control dicotyledonous weed;(3) post-emergeⅡ+ seedling spurt was better to control weed seedling.
