不同品种菌糠堆肥的理化特征比较分析

研究不同品种菌糠堆肥的理化性状,了解菌糠资源品种理化差异,有利于充分发挥不同菌糠资源的优势,提高菌糠利用价值.本研究以海鲜菇菌糠、平菇菌糠以及秀珍菇菌糠进行堆肥,每10天翻堆一次,考察菌糠堆肥的温度、pH、电导率、有机质以及总腐植酸等指标.经过60天堆肥,3种菌糠堆肥温度均能升高到55℃以上,高温持续时间分别为27、1...

Comparative Study of Physicochemical Characteristics of Different Species of Spent Mushroom Substrate in Compost

To study the physical and chemical characters of self-composting mature compost of different species of mushroom bran and to understand their physicochemical differences is helpful to make a full use of different kinds of mushroom bran resources, turn waste into treasure, and improve the utilization value of mushroom bran. The temperature, pH, conductivity, organic matter and total humic acid of seafood mushroom bran, pleurotus ostreatus mushroom bran and pleurotus geesteranus mushroom bran were investigated every 10 d. When they were composted for 60 d, the composting mature temperature of the three kinds of bran could be increased above 55℃, and the duration of high temperature was 27, 17 and 11 d, respectively. With the exception of pleurotus geesteranus mushroom bran, the EC value of each fungus bran increased gradually with the composting process and met the requirements of composting; the organic matter content decreased gradually by 6.1%, 12.2% and 15.0%, respectively; the total humic acid increased by 70.04%, 95.5% and 24.8%, respectively; the total humic acid of each fungus bran compost was the highest at 40 d, and that of seafood mushroom bran was 356 g/kg. The characteristics of different species of mushroom bran have certain differences, so the utilization of mushroom bran resources should be applied according to its characteristics.
