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。

Abstract: 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%.
