摘要 為篩選適宜鹽堿地大田的油莎豆專用除草劑,以自選油莎豆新品種—魯油莎1號為試驗材料,通過大田藥效篩選試驗,分析了不同種類除草劑對田間油莎豆安全性、雜草危害級別、防除效果及產(chǎn)量的影響。結(jié)果表明,對鹽堿地油莎豆安全性最高、防除效果最好的為苗前除草劑二甲戊靈及苗后除草劑撲草凈、高效氟吡甲禾靈。

Abstract In order to screen special herbicide suitable for field use, a self-selected variety of Luyousha No.1, was used as the test material, and the effects of different herbicides on field safety, weed hazard level, control effect and yield of Cyperus esculentus were analyzed through the field efficacy screening tests. From 11 kinds of herbicides, the pre-seedling and post-seedling herbicides with the highest safety and the best control effect were selected as pendimethamine, prometryn and highly effective fluprimetril.
