碳源调理剂对牛粪高温好氧堆肥发酵的影响

以牛粪为主要原料，以花生壳（T1）、玉米秸秆（T2）、玉米壳（T3）为添加剂，辅以禽畜粪便腐熟专用em菌剂，探讨不同碳源调理剂对牛粪高温好氧堆肥的影响，以期为固体废弃物的科学利用及解决废弃物带来的环境污染问题提供科学依据。结果表明：T1、T2、T3处理堆肥温度、铵态氮含量、pH、电导率值、种子发芽指数（GI）均符合堆肥腐熟要求。T2处理有机质含量（135.0 g/kg）、全氮含量（6.7 g/kg）、全磷含量（5.0 g/kg）、全钾含量（8.1 g/kg）显著（P＜0.05）高于T1处理（118.4 g/kg、5.2 g/kg、4.6 g/kg、6.5 g/kg、）和T3处理（122.2 g/kg、4.5 g/kg、4.4 g/kg、6.1 g/kg）。T3处理温度降至室温所需时间最短，为32 d，T2、T1处理分别为58 d、48 d。综合考虑堆肥进程、堆肥产品性状、碳源来源及成本，建议实际生产中用玉米壳作为牛粪高温好氧堆肥的碳源调理剂。

Effect of Carbon Source Conditioner on High Temperature Aerobic Compost Fermentation of Cow Manure

This experiment took cow dung as the main raw material, peanut shell (T1), corn stover (T2) and corn shell (T3) as the additives, and supplemented with special em agent for livestock manure decomposing to discuss the different source conditioning agents for high temperature of cow dung, which expected to provide a scientific basis for the scientific utilization of solid waste and the environmental pollution caused by waste. The results showed that the composting temperature, NH+4-N content, pH, EC value and seed germination index (GI) of T1, T2 and T3 were all in accordance with compost maturity requirements. Organic matter content (135.0 g/kg), total nitrogen content (6.7 g/kg), total phosphorus content (5.0 g/kg), and total potassium content (8.1 g/kg) of T2 treatment were significantly (P<0.05) higher than T1 treatment (118.4 g/kg, 5.2 g/kg, 4.6 g/kg, 6.5/kg) and T3 treatment (122.2 g/kg, 4.5 g/kg, 4.4 g/kg, 6.1 g/kg). The time required to drop to room temperature for the T3 treatment was the shortest, which was 32 d, and that for T2 and T1 treatments were 58 d and 48 d, respectively. Considering the composting process, compost product traits, carbon source and cost, it was recommended to use corn husk as the carbon source conditioning agent for high-temperature aerobic composting of cattle manure in actual production.
