| 摘 要： | 检测了紫茎泽兰地上部分榨取液对7种牧草种子萌发和幼苗生长的化感作用。结果表明：（1）紫茎泽兰地上部水浸提液对7种供试牧草种子的萌发均表现为强烈的抑制作用（P 〈0.05），对光叶紫花苕种子萌发的抑制作用显著小于对紫花苜蓿、白三叶、红三叶、东非狼尾草、非洲狗尾草和鸭茅种子萌发的抑制作用（P 〈0.05）；（2）从幼苗生长的测定结果分析，紫花苜蓿，红三叶和光叶紫花苕对低浓度紫茎泽兰叶片水提液不敏感，对高浓度提取液较敏感。白三叶、鸭茅、非洲狗尾草和东非狼尾草对紫茎泽兰的化感作用较敏感；（3）根据化感作用检测结果，分析认为光叶紫花苕、红三叶和紫花苜蓿是紫茎泽兰替代种植的适宜草种。

| Abstract: | In this study,we tested the allelopathy of Eupatorium Adenophorum on the germination and see-ding growth of seven forages seeds.The results showed as follows：（1）The extracts of fresh Eupatorium ade-nophorum had fiercer inhibitional effect on seeds germination of Medicago sativa ,Trifolium repens ,T .prat-ense ,Pennisetum clandestinum ,Setaria sphacelata ,Pennisetum clandestinum than Vicia villosa （P 〈0.05）.（2） The seeding growth of Medicago sativa ,Trifolium pretense and Vicia villosa were not sensitive to lower con-centration of Eupatorium Adenophorum extracts,but sensitive to higher concentration.The seeding growth of Trifolium repens ,Pennisetum clandestinum ,Setaria sphacelata and Pennisetum clandestinum were more sensi-tive to the extract of E .adenophora .（3）Our research suggested that Medicago sativa ,Vicia villosa and Trifo-lium pratense are appropriated forges that can be used to displace Eupatorium adenophorum in invaded regions. |
