摘    要:提高苜蓿的品质经常与降低其产量联系在一起,为了在保证品质的前提下有较高的产量,使得种植苜蓿的产值最大化,本试验以奶牛营养需要为基础,采用可消化干物质累计产量、粗蛋白累计产量和产奶净能累计产量三个指标,来判断紫花苜蓿的最佳收获期。

关 键 词:紫花苜蓿  刈割时期  可消化营养物质  累计产量

Abstract:The improvement of the quality of Medicago sativa L.and the reducement its yield is always contacted together,in order to ensure quality with high yield and maximize the output value of alfalfa,on the basement of the need of cows nutrition this experiment take the three indexes which are the accumulative yield of digestible dry matter,cumulative yield of crude protein and cumulative yield of the net energy to judge the best harvest-time of alfalfa.
Keywords:Medicago sativa L      Harvest-time  The digestible nutrition  Cumulative yield
