【中文摘要】 本文對平菇培養料通風發酵過程中不同階段培養料的微生物區系、溫度、pH 的變化進行了分析; 并繪制了堆料中溫度、pH、細菌數量和通風量的變化曲線。試驗結果表明: 采用通風發酵技術使培養料中中溫型有害的細菌、霉菌數量大大減少, 而有益的高溫放線菌數量增加, 并為平菇前期發菌減少污染及優勢生長創造了條件。

【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.
