菌渣代料栽培刺芹侧耳技术研究

Study on the cultivation of Pleurotus eryngii using its spent substrates

为探索循环利用刺芹侧耳（Pleurotus eryngii（DC.ex Fr.）Quel）菌渣栽培刺芹侧耳的可行性,优化菌渣代料栽培刺芹侧耳的条件与培养基配方,通过测定菌丝生长速率与生物学效率,比较分析了刺芹侧耳品种‘杏1’、‘杏2’和‘Z杏’在不同培养基上的栽培效果。结果表明：菌渣代料栽培刺芹侧耳的最佳条件为养菌温度24℃,培养基含水量65%,p H值6.0;在棉籽壳、苎麻副产物以及麻蔸等主料中加入40%~50%菌渣后产生的生物学效率最高,分别达到了67.59%、70.24%、71.02%,‘杏1’的生物学效率高于其他2个品种,但差异无统计学意义。本研究结果表明,生产中再次利用菌渣代料栽培刺芹侧耳是完全可行的。

Mycelial growth rate and biological efficiency of fruit body from ‘ Xing 1＇, ‘Xing 2＇ and ‘ Z xing＇, three different Pleurotus eryngii varieties, were determined by different spent substrates. The results showed that the optimal conditions for Pleurotus eryngii cultivation were at temperature 24 ℃, substrate with 65% medium moisture and p H 6.0; Adding 40%–50% of spent substrate into different basic substrates, including cottonseed hulls, ramie byproduct and ramie root mediums could reach higher biological efficiency with 67.59%, 70.24% and 71.02%, respectively. The biological efficiency of ‘Xing 1＇was higher than that of the other two varieties, but there was no significant difference. The results indicated that the spent substrate was suitable for Pleurotus eryngii cultivation.
