摘　　要：以川芝6号为发酵菌种,对三七渣固态发酵灵芝菌的培养基制备条件进行了研究和优化。结果表明,优化的培养基制备条件为采用过60目筛的三七渣,酵母粉添加量5%(质量分数,下同),磷酸二氢钾添加量0.025%,培养基含水量70%,不调节初始pH。在此条件下进行灵芝发酵,发酵培养物中灵芝菌丝体的质量分数最高可达31.27%。Taking Ganodorma lucidum （Chuan Zhi No.6） as the fermentation strain,the preparation condition of culture medium of solid-state fermentation from notoginseng residues was optimized.Results showed that the optimized conditions were particle size of notoginseng residues as 60 mesh, yeast powder 5 % （mass fraction）, potassium dihydrogen phosphate 0.025 % （mass fraction）, moisture content 70%, natural pH. Under this condition, the mass fraction of Ganodorma lucidum mycelium in fermenting medium could reach 31.27 %.
