摘要
研究平菇在不同C/N比麦草培养料中的物质转化结果表明:麦草栽培平菇后,C/N比值普遍下降。下降幅度随C/N比增加,下降趋势与干物质损失一致。干物质转化为菇体以C/N比50～60:1最高,而N素的利用率则以C/N比70:1左右最高。在平菇栽培过程中N的损失与培养料的C/N比大小呈负相关。
This paper deals with the Conversion of substances of Pleurotus Ostreatus in wheat straw culture medium with different C/N ratios. The results of the studies showed that after Pleurotus Ostreatus was cultured on wheat straw, C/N ratio generally descends .The descent range increases when C/N ratio becomes greater. The descent tendency is in agreement with dry substances into sporocarp is the highest when C/N ratio is 50-60 : 1. The utilization rate of N is the highest when C/N 'ratio is about 70 : 1 or so. And N loss has an apparent correlation with C/N natios the culture medium in Pleurotus Ostreatus culture process.
