| 摘 要： | 该文研究了添加不同辅料猪粪高温(＞60℃)堆肥发酵层的温度变化规律，结果表明随着堆肥发酵时间不同，堆肥高温层的位置和厚度呈动态变化，有明显的变化规律，即：各辅料处理的堆体高温发酵层出现在离顶部20 cm和离底部20 cm之间，高温发酵层厚度随着发酵期而递增。辅料对猪粪生物堆肥过程高温发酵期开始及其厚度、高温发酵期延续时间有显著影响，从辅料对猪粪高温堆肥发酵层温度变化的影响看，猪粪生物菌剂堆肥生产中选用20%左右砻糠和木屑作为辅料较适宜。

| Abstract: | Variations of layer temperature during pig manure microorganism composting with different amendments were studied. Results showed that positions and width of layers with high temperature changed dynamically during composting. Layer with high temperature presented to 20 cm from composting piles top to 20 cm from composting piles bottom, layers with high temperature increased with composting times. Effects of amendments on commencement and width of layers with high temperature, and its duration were obvious, according to variations of high temperature layers, 20% rice chaff and wood chaff as amendments were appropriate for pig manure microorganism composting. |
