【摘要】 本文利用不同的鸟巢菌对小麦、玉米和油菜的秸秆进行了降解试验 ,发现鸟巢菌对天然秸秆的体外干物质降解率 (IVDMD)最高可以达到 66.6% ,粗蛋白含量最高可以达到2 2 .5% ;硫酸铵对于鸟巢菌降解玉米和小麦秸秆的影响是不同的。对于鸟巢菌来说 ,添加硫酸铵 IVDMD和降解产物中粗蛋白含量的影响不显著 ;鸟巢菌降解玉米秸秆后生物量中氨基酸的含量测定结果 ,鸟巢菌能促进降解玉米秸秆中的氨基酸含量的增加 ;当向玉米秸秆中添加硫酸铵时 ,鸟巢菌能使降解后生物量中氨基酸含量进一步增加更多还原

【Abstract】 The article reported the digestability of wheat,maize and rapeseed stubbles with birds nest fungi.It was found that the maximal IVDMD (In Vitro Dry Matter Decline)reached 66.6%,and the protein content in the digested bio mass was 22.5%.Ammonium sulphate addition to the stubbles affected the digestion of wheat and maize stubbles by birds nest fungi variably.The addition of ammonium sulphate did not influence the protein content in the resulted bio mass remarkably.Amino acid analysis showed that birds nest fungi increased the amino acid content in the digested maize stubbles.Ammonium sulphate addition to the stubbles increased the amino acid content furthur.更多还原
