摘　　要：目的:筛选以枇杷枝屑代料栽培灵芝的最佳配方,为实现高产量和生产高品质的灵芝提供参考依据。方法:添加不同比例枇杷枝屑代料栽培灵芝,测定灵芝子实体生物转化率、孢子量及其多糖、三萜及黄酮含量。结果:枇杷枝屑代料栽培灵芝可正常出芝,产生并释放孢子,与杂木屑代料栽培相比,枇杷枝屑添加量为80%时,生物转化率增加了11.34%,但孢子产量差异不大;枇杷枝屑添加量为90%时,多糖含量增加了32.29%,三萜含量增加了30.58%;枇杷枝屑代料栽培灵芝对黄酮的影响不大。结论:枇杷枝屑代料栽培灵芝能提高灵芝的品质,根据综合评分枇杷枝屑添加量以80%为最适合。Objective： To select the best Ganoderma lucidum cultivation medium of replacing sawdust into loquat-branch dust,in order to realize high output and high quality production of Ganoderma lucidum. Methods： Loquat-branch dust was added as substitution in Ganoderma lucidum cultivation,its effects on the biomass and the content of Ganoderma polysaccharides,triterpenoids and flavonoids were analyzed. Results： By using loquat-branch dust in culture,Ganoderma lucidum grew well with normal fruiting body obtained and spores released. Compared with control group,the biological efficiency was increased by 11. 34%,when the addition of the loquatbranch dust was 80%,while the amount of spore had little difference. When the addition of the loquat-branch dust was 90%,the content of Ganoderma polysaccharides and triterpenoids was increased by 32. 29% and 30. 58% respectively,while the efficiency of flavonoids had little difference. Conclusion： Using loquat-branch dust cultivation can improve the quality of Ganoderma lucidum. According to the comprehensive score,80% loquat-branch dust is the most suitable cultivation medium.
