| 摘 要： | 用砂培法研究紫花苜蓿（Medicago sativa）的六个品种苗期地上部分水浸提液对鸭茅(Dactylis glomerata L.)的化感效应。结果表明，紫花苜蓿六个品种茎叶水浸提液对鸭茅的化感效应在供试品种间差异显著。游客、苜蓿对鸭茅的种子发芽及幼苗生长有抑制作用，但游客却对鸭茅的苗干重有促进作用；三得利和赛迪对鸭茅的种子发芽、根长及根干重有抑制作用，却对苗生长的影响无显著差异。此外，供试紫花苜蓿浸提液对鸭茅的化感作用，随着浓度的升高，抑制作用随之增强。

| Abstract: | In the experiment , Allelopathy of Medicago sativa on Dactylis glomerata L was studied through stem leaf water extract in seedling stage. It turned out that allelopathy of Medicago sativa on Dactylis glomerata L was evident. Eurek and Baralfa obviously inhibited germination and seeding growth ,but promoted leaf dry weight. Sanditi and Sadie was not significant on seeding length of Dactylis glomerata L.,but it can inhibited seeding length.Moreover, The results also show that the allelopathic inhibition rate increased with intense concentration of the water extracts. |
