摘要
为探索平菇发酵料最佳处理方式,对发酵料进行不同次数翻堆后将部分发酵料于70℃或80℃进行熟化处理,并与未熟化发酵料进行对比。测定不同翻堆次数后发酵料的理化性质(含水量、pH)、微生物(真菌、细菌、放线菌)变化趋势、干物质损耗情况。比较不同翻堆次数发酵料及熟化处理料对平菇菌丝生长及出菇的影响。结果表明,发酵料第1次翻堆时料中细菌、真菌、放线菌数量达到峰值,第2次翻堆后数量呈下降趋势。发酵料分别经70℃和80℃熟化处理后,料中微生物菌落明显减少。其中,70℃熟化后嗜热真菌、细菌、放线菌均少量存在;经过80℃熟化后发酵料中真菌几乎不可见,但仍存在嗜热放线菌。研究结果表明,发酵料在经过2次翻堆即可达到标准,再经过80℃熟化处理后效果更佳,表现为平菇菌丝生长较快、生物学效率较高。
In order to explore the best treatment of compost for caltivating Pleurotus ostreatus,after different turning times,some compost were sterilized at 70℃ or 80℃,and compared with unsterilized compost.The physicochemical properties(water content,pH),microbial population(fungi,bacteria,actinomyces)and dry matter loss of compost were measured after different turning times.The effects of sterilized compost and unsterilized compost with different turning times on P.ostreatus mycelia growth and fruiting were compared.The results showed that the number of bacteria,fungi and actinomyces reached the peak when the compost was turned over for the first time.After the second turning,the rial number showed a downward trend.After the compost was cured at 70℃ and 80℃ separately,the microbial colonies in the compost were significantly reduced.Among them,thermophilic fungi,bacteria and actinomyces all existed in small amount after sterilizing at 70℃.After sterilizing at 80℃,the fungi in the compost were almost invisible,but the thermophilic actinomyces were still visible.The results show that the compost can reach the standard after two turns.After sterilizing at 80℃,the effect is better,showing that P.ostreatus mycelia growth is faster and biological efficiency is higher.
