摘  要：
通过模拟降雨方法,对自然条件下不同堆放时间的猪粪进行降雨冲刷试验,同时对比分析了秸秆、土壤、裸露3种覆盖条件下,降雨对自然堆放条件下猪粪中不同氮形态径流流失的影响及其面源污染风险。结果表明,猪粪的氮素流失与降雨量密切相关,不同堆放时间猪粪径流中的总氮、氨态氮和硝态氮的浓度均随着降雨量的增加而逐渐下降;新鲜猪粪堆放7 d和堆放30 d的猪粪径流中氮素浓度和流失强度均较高,腐熟猪粪(堆放90 d)和堆放60 d的猪粪相比,其氮素更易通过径流流失;猪粪中氮主要是以氨态氮的形式流失,氨态氮和硝态氮平均流失强度分别为78.1 g/t和54.9 g/t;覆盖处理能显著降低猪粪氮素的流失强度,且土壤覆盖处理优于秸秆覆盖。

摘  要：
By simulating the rainfall method, the rainfall test of pig manure with different stacking time under natural conditions was carried out. At the same time, the loss of different nitrogen form runoff in pig manure under natural storage conditions under the conditions of straw, soil and bare cover were compared and analyzed. The results showed that the nitrogen loss of pig manure was closely related to rainfall, the concentrations of total nitrogen, ammonia nitrogen and nitrate nitrogen in pig manure runoff decreased with the increase of rainfall; Nitrogen concentration and loss intensity of the fresh pig manure runoff piled for 7 days and pig manure runoff piled for 30 days were higher, nitrogen of runoff piled for 90 days was more easily lost through runoff compared with runoff piled for 60 days. The nitrogen in pig manure was mainly lost in the form of ammonia nitrogen, the average loss intensity of ammonia nitrogen and nitrate nitrogen was 78.1 g/t and 54.9 g/t,respectively; The coverage treatment can significantly reduce the loss of pig manure nitrogen, and the soil cover treatment was better than the straw cover treatment.
