摘要:本文以金针菇苏金6号菌种为研究材料，采用固体发酵培养的方法在不同条件下（不同的培养基、不同的锗浓度）对锗进行富集，获得子实体，通过测定子实体的各项生物指标（生物量、多糖、有机锗含量等）对发酵条件进行优化。通过控制pH为6.5，菌丝22-24摄氏度,子实体13-15摄氏度。以及实验所测定的金针菇子实体的各项生物指标，可以获得结论：富锗金针菇栽培的最佳锗浓度为100μg/mL。

Abstract:In this paper,Flammulia velutipes Su jin No.6 strain as research material,using the method of solid fermentation culture under different conditions(Different culture media,different Ge concentrations)on germanium enrichment,obtain fruiting boby ,through the determination of biological indicators of fruiting body (biomass,polysaccharide,organic germanium )to optimize the inditions .Through the control of PH 6.5,the mycelium of 22-24 degrees Ceksius ,fruiting boby of 13-15degrees celsius, and the experimental determination of Flammulina velutipes fruiting biological ind icators ,may obtain the conclusion: the best of the Ge concentration Ge-rich golden mushroom  cultivation for 100-200ug/ml.
