摘要

[Objective]The paper was to analyze the control effect of replacement cultivation of several high quality forages against Eupatorium adenophorum.[Method]Five high quality forages including Lolium perenne,Dactylis glomerata,Setaria anceps,Trifolium repens and Medicago sativa were planted in the fields invaded by E.adenophorum,and their ecological adaptability and control effect against E.adenophorum were studied.[Result]Five kinds of forages could normally grow at the local land.The indexes such as coverage,plant height,fresh weight of stems and leaves of S.anceps were the highest,and it showed very strong ecological adaptability as well as the best control effect on E.adenophorum,up to 97.85%and 93.81%at the first and second year,respectively,indicating good sustainable control effect.D.glomerata ranked the second place,of which the coverage after one year was 86%and the control effect on E.adenophorum was89.68%.The other species showed poor control effect on E.adenophorum because of slow growth rate and heavily damage from companion weeds even they could establish dominant communities.[Conclusion]The paper provided reference for ecological control against E.adenophorum in local land and ecological restoration of invasive land.
