摘　　要：采用模拟装置对畜禽粪便在雨水冲刷下的氮磷流失规律进行了研究,为了试验结果可控性,采用人工降雨与模拟降雨相结合的方式,分别采集畜禽粪便堆体表层、30、50 cm处的样本。分析结果发现,降雨冲刷可导致畜禽粪便中65%的氮和55%的磷流失,且流失率主要与畜禽粪便的堆置时间和堆体高度有关,与单次降雨量关系不大。并结合流失规律开展了蚯蚓强化降解堆沤池的研究和蚯蚓生长条件的动力学优化,结果表明,堆沤池对堆体中的氮磷元素的流失有明显的控制作用。It adopted analog devices to investigate N＆P loss of animal manure in the rain erosion. To the controllability of the experimental process, the experiment has taken a combination of artificial rainfall and simulated rainfall, the samples were collected for analysis from the surface, 30, 50 cm of livestock and poultry manure. The results showed that 65% loss of nitrogen and 55% loss of the phosphorus can by the way of rainfall erosion, wastage rates of nutrient elements mainly related to stacking time and the pile height, little relationship with singlerainfall. Combined with the loss rules to carry out the studies of the earthworms to strengthen the degradation of composting pool and dynamic optimization of earthworm growth conditions. Studies have shown that degradation of composting pool has significant role in control the loss of nitrogen and phosphorus elements.
