摘　　要：薇甘菊(Mikania micrantha)在台山市自发生以来逐渐传播蔓延,给林业带来了严重危害。该试验选取了灌薇净、2,4-D和益霖薇净3种除草剂在桉树人工林地中进行喷洒,记录防除后第60天薇甘菊的枯死率,并进行多重比较。结果表明:益霖薇净防除效果最好,防除60d后,薇甘菊枯死率达97%以上,2,4-D次之,灌薇净防效最差。综合考虑树种安全,环境友好和经济效益等方面,建议使用24%益霖薇净水剂防除桉树人工林中的薇甘菊。Mikania micranthahas spread gradually since its occurrence in Taishan City, which has brought serious harm toforestry.
