摘　　要：本试验以白三叶和红三叶草等做为主要原料,玉米秸秆为添加料进行混合青贮,经密闭发酵贮藏60d后,分析混合处理对三叶草青贮发酵品质和营养成分的影响。结果表明:三叶草能单独青贮,但不能调制出发酵品质良好的青贮饲料。与玉米秸秆混合青贮可显著降低三叶草青贮饲料的pH值和氨态氮/总氮(NH3-N/TN)比值(P<0.05);与玉米秸秆混合处理后青贮饲料的可溶性碳水化合物留存量明显高于对照组。通过与玉米秸秆混合青贮可以明显改善三叶草青贮饲料的发酵品质。Red clover and white clover were ensiled with corn stover and stored for 60 days in order to investigate the effect of supplying corn strover （CS） on clover silage quality. The result indicated that the clover alone could be sliage, but could not be excellent silage. Mixed with corn stover, the silage treament decreased its pH value and content of NH3-N/TN（P〈0.05）, as well as increased its WSC obviously.The quality of clover silage could be improved by mixing with corn stover.
