摘    要:采用高温堆肥模拟试验研究了有效微生物EM和两种调理剂稻草、蚯蚓粪在奶牛粪堆肥中保氮和除臭的效应及各自适宜的添加比例。结果表明,在高温条件下,EM、稻草和蚯蚓粪均可明显降低奶牛粪中NH3和H2S的挥发,EM各添加比例的NH3去除率为7.06%~11.80%,H2S去除率为5.30%~10.81%;稻草各添加比例的NH3去除率为11.76%~66.03%,H2S去除率为10.63%~60.28%;蚯蚓粪各添加比例的NH3去除率为10.07%~50.75%,H2S去除率为13.95%~56.78%。同时,随着添加比例的提高,有效微生物EM、稻草和蚯蚓粪对NH3和H2S的去除率增大,达到奶牛粪堆肥中最大的保氮除臭效果时,EM的添加比例为3%、稻草的添加比例为30%、蚯蚓粪的添加比例为10%。

Abstract:Simulation experiment was taken under high temperature to study nitrogen preserving and deodorizing effect as well as optimal adding proportion of effective microorganism EM and two conditioners ricestraw and wormcast in cow manure composting. Results showed that EM, ricestraw and wormcast all can obviously decrease volatilization amount of NH3 and H2S in high temperature of cow manure composting. To different adding rates of EM, removal efficiency of NH3 was 7.06%~11.80% and that of H2S was 5.30%~10.81%. T...
