摘　　要：以小麦为主要栽培基质,通过添加不同的氮源和无机盐,选用优质蛹虫草菌株CM-16进行人工培养,探索这2个因素对蛹虫草子座产量及虫草素和腺苷的影响。结果表明:栽培过程中选用6g·L^(-1)的蛋白胨作为最佳氮源,子座干样质量、虫草素和腺苷的生成量均较高,分别为43.1g·盒^(-1)、3.95mg·g-1和2.35mg·g^(-1)。无机盐则选择1.0mg·L^(-1)的硫酸亚铁最为合适,此时子座干样质量、虫草素和腺苷的生成量分别为48.8g·盒^(-1)、4.98mg·g^(-1)和2.10mg·g^(-1)。Wheat was the main culture medium in which different kinds of nitrogen resource and inorganic salt were added. High quality Cordyceps militaris CM-16 was cultured in wheat medium and the effects of 2 factors on yield of stroma, cordycepin and adenosine was studied. The results showed that 6 g · g^-1 peptone was optimal nitrogen source in cultivation. The production of stoma,cordycepin and adenosine were 43. 1 g · box^-1 ,3. 95 mg · g^- 1 and 2. 35 mg · g^-1 respectively. The optimal inorganic salt was 1.0 mg · L^-1 ferrous sulfate. The production of stoma, cordycepin and adenosine were 48. 8 g · box^-1 ,4. 98 mg · g^-1 and 2. 10 mg · g^-1 under this cultivation conditions.
