本研究旨在将多花黑麦草与大豆秸秆以不同比例混合青贮，评价其发酵品质，筛选出适宜的混合比例。试验设多花黑麦草与大豆秸秆的混合比例为10∶0（对照组）、9∶1（S1）、8∶2（S2）、7∶3（S3）和6∶4（S4）5个处理。青贮42 d后打开青贮桶，测定青贮饲料的发酵品质。结果表明，多花黑麦草与大豆秸秆混合青贮显著提高了干物质含量，降低了挥发性脂肪酸含量和氨态氮/总氮的值，其中S2和S3处理的丁酸和氨态氮/总氮值最低。V-Score 评分显示各混贮组的V-Score 得分均高于对照组，其中S2和S3处理的发酵品质为优等，而对照组的发酵品质为不良。从发酵品质和秸秆利用最大化的角度出发，建议将多花黑麦草和大豆秸秆以7∶3的比例混合青贮较为适宜。

The mixed fermentation quality of Italian ryegrass (Lolium multiflorum )and soybean (Glycine max)straw was studied through the following proportions of 10∶0 (Control),9∶1 (S1 ),8∶2 (S2 ),7∶3 (S3 )and 6∶4 (S4 ).The silos for each mixture were opened on 42 d after ensiling and the fermentation quality was measured.The results showed that the dry matter content was increased significantly,but the NH3-N to total nitrogen (TN)ratio and the content of volatile fatty acids were significantly decreased by adding soybean straw.The butyric acid content and NH3-N to TN ratio were decreased markedly in the treatment of S2 and S3 . The V-Scores were higher as compared with the control,S2 and S3 treatment indicated good fermentation quali-ty.It was suggested that the 7∶3 mixed proportions of Italian ryegrass and soybean straw was best for impro-ving fermentation quality and maximum using soybean straw.
