摘要：

本文对三个多花黑麦草与两个紫花苜蓿品种的茎、叶和根的水浸提液化感作用进行了研究分析。结果表明：三种花黑麦草与两种紫花苜蓿品种对受体赛迪7有一定的化感影响，对赛迪7的种子发芽都有抑制作用；多花黑麦草 Barextra和Barmega两个品种的根、茎、叶水浸提液对赛迪7的苗高、根长及生物量的积累都存在低促高抑的化感作用；供体不同部位化感作用不同；紫花苜蓿两个品种茎的水浸提液在三种浓度下均对赛迪7的根长有促进作用，对苗高有抑制作用。

Abstract:

The allelopathy of several Lolium multifolorum and Medicago sativa L was studied in the paper, and the acceptor was Sardi 7 seed. The results indicated that the aqueous extracts from roots, stems and leaves restrained the seed germination of Sardi 7; The aqueous extracts of Lolium multifolorum Barextra and Barmega have allelopathy on the seeding height、 root length and biomass of Sardi 7，and there was inhibition effect at higher concentration and there was the enhancement effect at lower concentration; The allelopathy of the different tissue is not the same; The extracts from stems of Medicago sativa L with the three different contentration have increased effection on the root length of Sardi 7， but restained on the seeding height.
