【中文摘要】 本文对平菇培养料通风发酵过程中不同阶段培养料的微生物区系、温度、pH 的变化进行了分析; 并绘制了堆料中温度、pH、细菌数量和通风量的变化曲线。试验结果表明: 采用通风发酵技术使培养料中中温型有害的细菌、霉菌数量大大减少, 而有益的高温放线菌数量增加, 并为平菇前期发菌减少污染及优势生长创造了条件。
【英文摘要】 The variation of microflora,temperature and pH value of ordinary fermentation and ventilation fermentation of Pleurotus ostreatus compost at different stages has been studied.We also draw curves of variation of temperature,pH value and the quantities of bacteria according to the different amount of ventilation.By studying their dynamic variation,we come to the conclusion that the quantities of the harmful mesophiles are reduced greatly by ventilation fermentation technique adopted in the compost.Meanwhile the quantities of the conductive thermophilie actinomycetes are increased.Therefore,the suitable conditions are created for the growth of Pleurotus ostreatus hyphae.
