摘　　要：薇甘菊Mikania micrantha作为一种外来入侵植物,自传入中山市以来,不断传播蔓延,给林业生态带来了严重危害。本试验选取紫薇清、益霖薇净和灌薇净3种除草剂在废弃果园进行喷洒,定期查看薇甘菊的枯死率并观察药害情况。结果表明:喷洒益霖薇净7 d后的薇甘菊枯死率达到98%以上;紫薇清和灌薇净的薇甘菊枯死率达到98%以上需要45 d左右。在根茎枯死率和药害等级上,益霖薇净对薇甘菊的防治效果同样高于紫薇清和灌薇净。综上所述,益霖薇净在3种药剂中对薇甘菊的防治效果最好。建议在林地、非耕地等薇甘菊危害较大的区域,使用益霖薇净作为高效防治药剂。Mikania micrantha,as an invasive plant,grows very fast and has spread continuously since its occurrence in Zhongshan City,which has brought serious harm to forestry.In order to screen out the chemical agents with better control effect on M.micrantha,this experiment selected three herbicides of Ziweiqing,aminocyclopyrachlor and Guanweijing to spray in abandoned orchards,and regularly checked the death rate and phytotoxicity of M.micrantha.The results showed that the death rate of M.micrantha reached more than 98%after 7 days of spraying aminochloropyridinic acid.It takes about 45 days for the death rate of Ziweiqing and Guanweijing to reach more than 98%.In terms of the root and stem death rate and the level of phytotoxicity,the control effect of aminocyclopyrachlor on M.micrantha was also higher than that of Ziweiqing and Guanweijing.In summary,among the three agents,aminocyclopyrachlor has the best control effect on M.micrantha.It is suggested that aminocyclopyrachlor can be used as an efficient control agent in areas with great harm to M.micrantha such as forest land and non-cultivated land.
