摘要
[目的]研究适于恩平簕菜种植中田间杂草防除的除草剂。[方法]通过田间试验,测定除草剂茎叶喷雾对簕菜安全性及杂草防除效果。[结果]宝成、灭草松、盖草能对簕菜相对安全,莠去津出现轻微药害现象。盖草能单独使用、宝成单独使用杂草防治效果较差,鲜重防效仅为26.3%和44.7%。盖草能和灭草松混合施用,无药害现象,且相对防效较佳,株数和鲜重相对防效分别达95.9%和89.5%。[结论]在恩平簕菜种植中,盖草能和灭草松混合施用,除草效果较好,可进一步推广应用。
[Objective]To find adequate broadleaf herbicides in Acanthopanax trifoliatus( L.) Merr fields.[Method]The security of herbicides on Acanthopanax trifoliatus (L.) Merr and the weed control effect were evaluated by field foliage spray test.[Result]Titus, bentazone, gallant super were relatively safe to Acanthopanax trifoliatus (L.) Merr.There was a slight phytotoxicity of atrazine.The control effects of using titus and gallant super independently were worse to weeds, fresh weight control effects were only 26.3% and 44.7%.The mixture of gallant super and bentazone had no pesticide damage, and the relative control effect was better.The relative control effect of plant number and fresh weight was 95.9% and 89.5%, respectively.[Conclusion]In the planting of Acanthopanax trifoliatus (L.) Merr.in Enping, the combination of gallant super and bentazone has better weed control effect and can be further popularized and applied.
