摘　　要：在同等环境条件下按不同比例混播禾本科牧草无芒雀麦和豆科牧草紫花苜蓿,结合两种牧草各自的生态习性、生活型和生态幅等指标比较两种牧草发芽率、株高和生物量,结果表明,当无芒雀麦和紫花苜蓿的混播比例为20∶20时,其平均生物量最高.Mixed grass of Smooth Brome and Legumes alfalfa at different proportion are planted in the same environmental. The ecological habit, life form and ecological sites be combined, forage germination ,plant height and biomass of two grass by two different processing are compared. Result indicated： when the proportion of two grass is 20 ： 20, the average biomass of two grass is the highest.
