摘　　要：以青海柴达木盆地诺木洪当地野生大肥菇子实体为试材,研究了大肥菇菌丝在不同碳源、氮源、碳氮比以及不同pH条件对菌丝生长的影响。结果表明:大肥菇菌丝生长最适合的碳源和氮源分别是果糖和酵母膏;最适宜的碳氮比为35∶1;菌丝生长明显的pH范围是7.5～8.5,但以pH 7.5时最佳。Sporocarp of wild Agaricus bitorquis from Qaidam Basin of Qinghai Province were used as test material,the effect on growth of Agaricus bitorquis were studied under different conditions of carbon source,nitrogen source,carbon nitrogen ratio,and pH scale.The results showed that the most suitable carbon source and nitrogen source were fructose and yeast extract respectively,the most suitable carbon nitrogen ratio was 35∶1,and mycelium culture of could be done from 7.5~8.5 of pH scale,but 7.5 was the best.
