为了高效降解青贮香蕉茎叶中的单宁，本试验研究添加产单宁酶菌株——泡盛曲霉FCYN206对香蕉茎叶青贮品质的影响。试验设计对照组、泡盛曲霉FCYN206菌组、EM菌组和EM菌+泡盛曲霉FCYN206菌组，青贮20 d，开封测定青贮品质。结果表明：与对照组比，菌株泡盛曲霉FCYN206可减少干物质损失，显著降低单宁含量 （P＜0.05），但对饲料粗蛋白质含量无明显作用；EM菌能提高饲料粗蛋白质含量，但对单宁降解无效果；EM菌+泡盛曲霉FCYN206组pH为3.91，达到青贮标准，感官评价最好，且与对照组相比，单宁含量显著降低4.49%（P＜0.05）。添加泡盛曲霉FCYN206对EM菌青贮香蕉茎叶中的单宁有明显降解作用，能改善青贮香蕉茎叶饲料的感官品质和风味。

［Abstract］To effectively degrade the tannin content in banana stem and leaf silage，this experiment was conducted to investigate the effect of Aspergillus awamori FCYN206 on fermentation quality and chemical composition of banana stem and leaf silage.Three fermentation groups were designed：A.awamori FCYN206 group，EM （Effective Microorganisms，EM）strain group，EM strain+A.awamori FCYN206 group.The silage quality of them were statistically analyzed after 20 days.The results showed as follow：compared with the control group（without additive），dry matter content of silage was improved and tannin content of silage was obviously reduced after adding A.awamori FCYN206（A.awamori FCYN206 group），but it had no obvious effect on crude protein content of silage.After adding EM strain（EM strain group），crude protein content of silage was improved.However，it had no effect on the degradation of tannin.The pH value of silage was 3.91，which reached to the standard of good or best silage after adding EM strain and A.awamori FCYN206 group.Notably，tannin of silage was obviously reduced after adding them.So adding A.awamori FCYN206 could effectively degrade the tannin content in banana stem and leaf silage and improve fermentation quality of silage.

香蕉茎叶等副产品一直被当作废弃物，直接就地还田或焚烧，不仅浪费了大量的资源，同时对环境产生严重污染。研究表明，香蕉茎叶中含有大量的蛋白质、脂肪、纤维素和半纤维素等营养物质，可作为优良的饲料资源（陈蓉等，2000）。……
