摘  要:
以苎麻和杂交狼尾草为青贮原料,进行单独和混合青贮效果研究,为生产提供优质青贮杂交狼尾草、苎麻单独和混合青贮奠定基础。试验设计7个杂交狼尾草和苎麻混合比例,按鲜重计分别为100∶0(P100)、70∶30(PR73)、60∶40(PR64)、50∶50(PR55)、40∶60(PR46)、30∶70(PR37)和0∶100(R100)。结果表明:苎麻单独青贮的青贮料品质最差,表现为青贮料的pH值、乙酸、丁酸和氨态氮含量最高,干物质、乳酸和半纤维含量最低;杂交狼尾草单独青贮的青贮品质最好,表现为青贮料的干物质、可溶性碳水化合物、中性洗涤纤维、半纤维素、粗蛋白和乳酸含量最高,pH值、乙酸、丁酸和氨态氮最低;随着杂交狼尾草混合比例升高,青贮料品质明显提高。

摘  要:
To improve the quality of silage,7various ratios of the mixture of ramie and hybrid Pennisetum,i.e.,100∶0(P100),70∶30(PR73),60∶40(PR64),50∶50(PR55),40∶60(PR46),30∶70(PR37)and 0∶100(R100),were tested.After fermented for 60 days at ambient temperature,the nutritional value of the silages was determined with 3replicates for each mixture.The results showed that the quality of R100 silage was the poorest among all.It was the highest in pH,acetic acid,butyric acid and ammonia nitrogen contents,and the lowest inlactic acid and hemicellulose contents.The quality of P100 silage was the best,containing the highest amounts of dry matters,water soluble-carbohydrates,neutral detergent fiber,hemicellulose,crude protein and lactic acid,and the lowest on pH,acetic acid,butyric acid and ammonia nitrogen minimum contents among the mixtures.It appeared that the greater the portion of hybrid Pennisetumin the mixture,the better the quality of the fermented silage.
