摘　　要：研究了5种碳源和5种氮源对平菇菌株新831菌丝生长的影响。结果表明,不同碳氮源对菌丝的生长速度和生长势有显著影响,表明该菌株同化不同碳氮源的能力有较大差异。新831菌丝生长的最适碳源是葡萄糖、淀粉和CMCNa,蔗糖次之,麦芽糖最差;最适氮源是酵母粉和蛋白胨,(NH4)2SO4次之,NaNO3较差,尿素最差。The effect of 5 carbon sources and 5 nitrogen sources on the mycelium growth of New-831 in P/eurotus ostremus was studied. The results showed that the different C-sources and N-sources had remarkable effects on mycelium growth rate and growth vigor of the P. ostreatus, also there was a greater difference in the ability of assimilating the different carbon and nitrogen sources.The experiment revealed that the optimum carbon sources were glucose, starch and CMCNa, the sucrose took second place and the maltose was the worst;The optimum nitrogen sources were yeast powder and peptone,the （NH4）2SO4 was secondary, NaNO3 was relatively poorer and the urea was the worst.
