食用菌菌糠再利用技术研究

为了解决食用菌产业发展中的菌糠再利用技术问题，对不同菌糠的营养成分含量进行分析，对菌糠替代部分木屑、棉籽壳和麦麸栽培食用菌的效果，以及施用菌糠有机肥对脐橙产量和品质的影响进行试验。结果表明，菌糠可替代木屑、棉籽壳和麦麸作为培养料，栽培秀珍菇、金福菇和鲍鱼菇的生物效率分别达到64.95%、84.65%和70.49%，与CK差异不显著；施用菌糠有机肥的脐橙平均产量比CK增加5.54kg/株，达到极显著差异，并可提高脐橙的品质，改良果园土壤的结构。研究结果显示，食用菌菌糠的再利用技术对提高农业资源的有效循环利用具有重要的实践指导意义。

Studying the Techniques for Reuse of Spent Mushroom Substrates

To face the problem of vast spent mushroom substrate (SMS) produced from mushroom industries, we analyzed the nutritive compounds of various SMS and studied the bio-efficiency of applying SMS as substitutes for sawdust, cottonseed hull and wheat bran on mushroom cultivation, as well as the effects on organic fertilizer for the yield and quality of Navel orange production. Results showed the possibility of re-utilizing SMS as substrates for Pleurotus cornucopiae, Tricholoma lobayense and Pleurotus abalonus with the bio-efficient for about 64.95%、84.65% and 70.49%, respectively, which were similar as it of CK group obtained. Comparing to CK group, use SMS as organic fertilizer increased the average output of Navel orange for 5.54kg per tree significantly, improved fruit quality and modified garden soil structure. Results indicated that re-utilization of SMS would apply an important role in recycling of natural resources in agricultural production.
