以L808为试验菌株，研究了香菇不同生育阶段培养料中碳、氮吸收利用规律与5～15、10～20、15～25、10～30 ℃(自然常温)4个温度区间香菇产量及品质(蛋白质、可溶性糖、纤维素)的相关性。结果表明，在10～20 ℃温度区间香菇产量最高，5～15 ℃温度区间香菇品质最好。随着香菇生长阶段的推移和出菇潮次的增加，香菇培养料中碳的含量呈现逐渐降低趋势，且与香菇产量和品质相关性极为密切，相关系数达极显著水平；香菇产量和香菇中蛋白质、可溶性糖含量越高的温度区间内，培养料中碳的含量下降幅度也较大。培养料中氮的含量则呈现先升高而后逐渐降低的趋势，香菇中蛋白质含量较高的温度区间内，培养料中氮含量降幅相对也较大，相关系数达显著水平。

By using L808 as test strains， correlation between the utilization of carbon and nitrogen in the culture material of lentinusedodes at different growth stages and the yield as well as quality(protein， soluble sugar， cellulose) of lentinusedodes which grow at 4 different temperature ranges as 5～15、 10～20、 15～25 and 10～30 ℃ (natural temperature) wereanalyzed. The results showed that the yield of shiitake mushrooms was the highest in the temperature range of 10～20 ℃， and the quality of shiitake mushrooms was the best in the temperature range of 5～15 ℃. With the passage of lentinusedodes growth stage and the increase of edodes emergence tide， the content of carbon in lentinusedodes culture material decreased gradually， and the correlation coefficient was extremely significant with the yield and quality of lentinusedodes. In the temperature range where the yield， protein content and soluble sugar content were higher， the carbon content in the growing materials also decreased significantly. The nitrogen content in the cultivation materials showed a trend that it increased in the initial period and then gradually decreased. In the temperature range where the protein content in the product washigher， the nitrogen content in the cultivation materials decreases relatively， and the correlation coefficient reaches a significant level.
