摘　　要：添加不同用量的茶枝屑进行灵芝的代料栽培,并分析灵芝的生物转化率和灵芝多糖和总三萜的含量。结果表明:灵芝在茶枝屑代料培养基上能正常生长、出芝,产生和释放孢子,灵芝的生物转化率比杂木屑代料栽培降低了6.25%～31.33%,灵芝多糖含量高3.03%～28.28%,灵芝总三萜含量高2.62%～17.40%。认为茶枝屑可以作为灵芝栽培新的代料,茶枝屑用量应控制在70%以内。Adding tea-branch dust as substitution in Ganoderma lucidum cultivation,its effects on the biomass and the content of Ganoderma polysaccharide and triterpenes were analyzed.The results showed that,by using tea-branch dust in culture,Ganoderma lucidum grew well with normal fruits obtained and spores released.Comparing with control group,the Ganoderma lucidum in substitution group decreased the biological efficiency by 6.25%-31.33%,increased the content of polysaccharide and triterpenes 3.03%-28.28% and 2.62%-17.40%,respectively.The results suggest that tea-branch dust can be used as a substitution in Ganoderma lucidum cultivation but the application amount should be not more than 70%.
