摘　　要：为探究品种、刈割时期对紫花苜蓿(Medicago sativa L.)营养特性的影响,以11个苜蓿品种为原料,在7种刈割时期分别测其DM、CP、NDF、ADF、WSC、Ash、BC。结果表明:11个不同苜蓿品种间的DM、CP、NDF、ADF、WSC、Ash、BC含量差异极显著(P<0.01)。苜蓿在第二茬的现蕾期、初花期都有良好的营养储存。综合分析后苜蓿在第二茬初花期最有利于青贮。The effect of varieties and harvest periods on quality ofalfalfa were studied. 11 varieties of alfalfa in 7 kinds of harvest periods were measured DM, CP, NDF, ADF, WSC, Ash, BC. The results showed that the DM, CP, NDF, ADF, WSC, Ash, BC content of 11 different alfalfa varieties was significantly different （P〈0.01） . The second cut of alfalfa in the budding stage, early flowering had good nutrition store. Concluded the second cut of alfalfa in early flowering was favorable of silage after a comprehensive analysis.
