摘　　要：为了进一步探索生物发酵床发酵机理。分析发酵床不同断面温湿度的变化及与猪舍环境小气候的关联。结果表明:(1)发酵床不同断面温度变化差异显著(P<0.01),其中10cm断面温度较表层提高2.56℃(P<0.05),20～40cm断面温度较表层提高7.10～9.42℃(P<0.01);(2)发酵床10cm断面垫料含水率较20cm和30cm断面分别高11.5%(P<0.05)和13.5%(P<0.05),20cm断面含水率与30cm断面差异不显著(P>0.05);(3)发酵床不同断面温度和含水率与环境小气候相关性不显著(P>0.05)。由试验结果可见,发酵床温度不会随外界环境温湿度的变化而有较大变化,其表层和内部温度能维持相对稳定。In this study, association between temperature and humidity changing of different cross-section of microorganism fermentation bed and micro-climate condition of pigsty was analyzed to discover the mechanism of microorganism fermentation bed. The results showed that： （1） There was significant difference in temperature changing between different cross-sections of microorganism fermentation bed （P〈0.01）. Temperature of cross-section at 10 cm was increased 2.56℃ than surface （P〈0.05）, Temperature of cross-section at 20-40 cm was increased 7.10-9.42℃ than surface （P〈0.01）. （2） The packing moisture content of cross-section of fermentation bed in 10cm was higher 11.5% than 20 cm （P〈0.05） and 13.5% than 30 cm （P〈0.05）, respectively. There were no significant moisture content difference between cross-section at 20 cm and 30 cm （P〉0.05）. （3） There were no significant association between temperature and moisture content of different cross-section and micro-climate condition （P〉0.05）. The results showed that, microorganism fermentation bed temperature did not vary with the change of environmental temperature and humidity, the surface and internal temperature could be maintained relatively stable.
