摘　　要：在原料不同含水量(75.3%、64.2%、54.6%)下添加绿汁发酵液(5ml/kg)对扁穗牛鞭草进行青贮,通过感官评定和化学分析对青贮料的发酵品质进行综合分析。结果表明,原料中、低含水量时,青贮料的茎叶结构保存较完整,感官评分较高;pH值、氨态氮含量明显低于高含水量时,乳酸菌数量和粗蛋白含量明显高于高含水量时(P<0.05);但是,低含水量下青贮料杂菌数量明显高于中含水量下(P<0.05)。综合分析,原料64.2%含水量、添加5 ml/kg绿汁发酵液是扁穗牛鞭草较适宜的青贮条件。The quality of whipgrass silages were evaluated in different moisture content treatments （75.3%, 64.2% ,54.6%） with the previously fermented juice （PFJ） （5 ml/kg）. After 45 d ensilaged, the quality of silages were analyzed from the visual and nutrition values. The results showed that in moisture 64.2% and 54.6%, the stems and leaves of the silage were kept well, which got higher scores in the sensory value estimate, the pH and amount of ammonia-N were lower, and the quantity of lactobacillus and the amount of crude protein were higher than that of in moisture 75.3%. But the quantity of other bacteria in moisture 54.6% was significantly higher than that of in moisture 64.2%. So it was the best choice to ensilage whipgrass in moisture 64.2% with 5 ml/kg previously fermented juice.
