摘　　要：试验采用生物检测法,研究紫花苜蓿根、茎、叶、土壤浸提液对蒙古冰草、红豆草、新麦草、无芒雀麦、紫花苜蓿种子发芽率的影响。结果表明,不同浓度的紫花苜蓿根、茎、叶、土壤浸提液对不同受体牧草种子发芽率的影响差异很大,根、茎、叶和土壤浸提液对无芒雀麦种子发芽有促进作用,而对蒙古冰草、新麦草、红豆草、紫花苜蓿种子发芽有抑制作用。The effects of extracts of alfalfa root, stem, leaves and Soil on Medicago sativa, Agropyron mongolicurn, Psathyrostachys jucea , Onobrychis vici folia and Bromus inermis seed germination rate were studied. The results showed that there were significant differences in effects of extracts of alfalfa root, stem, leaves and soil in different concentration on seed germination rate of different recipient forages, extracts of alfalfa roots, stems, leaves and soil had promotional effects on seed germination of Bromus inermis, while had inhibitive effects on seed germination of Agropyron mongolicum, Psathyrostachys jucea, Onobrychis vici folia , Medicago sativa .
