【摘要】 试验研究结果表明,豆科牧草羽叶决明与稻草、木屑及沼渣不同混合培养料对大球盖菇子实体产量及其氨基酸含量的影响各异,以羽叶决明+沼渣混合培养料(处理Ⅰ)栽培大球盖菇,其子实体产量比处理Ⅱ(稻草+沼渣)和处理Ⅲ(稻草+木屑)分别提高12.5%及29.4%;而其子实体氨基酸总量、必需氨基酸、儿童氨基酸、硫氨基酸、支链氨基酸、鲜味氨基酸和甜味氨基酸含量分别高于处理Ⅱ、处理Ⅲ32.02%、134.37%,45.67%、101.07%,51.69%、112.88%,19.33%、74.92%,45.96%、102.01%,62.50%、315.86%和32.31%、84.55%;其子实体中芬香族氨基酸含量比处理Ⅱ降低48.78%,但比处理Ⅲ提高92.7%。总体评价处理Ⅰ氨基酸评分(AAS)为61,氨基酸比值系数分为78.9,均高于处理Ⅱ和处理Ⅲ,有助于提高菇类品质。更多还原

【Abstract】 The yield and content of amino acid(AA)in fruit body of Stropharia rugosoannlata cultured on leguminous grass and biogas residue were studied.The results show that the yields of fruit body cultured with leguminous grass and biogas residue(Treatment Ⅰ)increase 12.5% and 29.4% respectively,higher than those of treatment Ⅱ(rice straw and biogas residue culture)and treatment Ⅲ(rice straw and wood bits culture);the contents of total AA,EAA,children’s AA,sulfur AA,branched chain AA,delicious AA,and sweet AA are 32.02%,134.37%;45.67%,101.07%;51.69%,(112.88%);19.33%,74.92%;45.96%,102.01%;62.50%,315.86%;and 32.31%,84.55%;higher than those of treatment Ⅱ and treatment Ⅲ,respectively.The content of aromatic AA in fruit body of treatment Ⅰ decreases 48.78%,lower than that of treatment Ⅱ,but increases 92.7%,higher than that of treatment Ⅲ.As far as comprehensive estimation is concern,AA score of treatment Ⅰ is 61,the ratio coefficient of AA is 78.9,both of them are higher than those of treatments Ⅱ and Ⅲ.Leguminous grass and biogas residue treatment improves the quality of edible fungus.更多还原
