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10 cm断面温度较表层提高2.56℃ (P<0.05)，20~40 cm断面温度较表层提高7.10~9.42℃ (P<0.01)；（2）发酵床10 cm断面垫料含水率较20 cm和30 cm断面分别高11.5% (P<0.05)和13.5% (P<0.05)，20 cm断面含水率与30 cm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。

Abstract:

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 20cm (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, microorganism fermentation bed temperature does not vary with the change of environmental temperature and humidity, the surface and internal temperature can be maintained relatively stable.
