多花黑麦草与大豆秸秆混合青贮发酵品质的研究
A study on fermentation quality of Italian ryegrass and soybean straw mixed silage
摘要
Abstract
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.关键词
