密闭箱处理蛋鸡粪的氧化亚氮氨气排放研究

Emission of Nitrous Oxide and Ammonia from Closed Composting Bins Containing

采用密闭箱处理蛋鸡粪的方法,研究了密闭箱内产生的氧化亚氮、氨气的排放规律、影响因子及两者存在的内在联系。结果表明,氧化亚氮的产生与有机质的含量以及蛋鸡粪内部的氧气状况密切相关;氨气与氧化亚氮的逐日排放变化规律存在很大的相似性;蛋鸡粪的内部温度作用表现不明显,受外界气温影响很小。

It has been found from our test that under a relative constant amount of both nitrous oxide and ammonia, the well-known green house gases, was released from closed composting bins full of layer-hen manure. It has been also found that both nitrous oxide and ammonia released from the bins were correlated well with the organic matters inside the bins. So were with the contents of oxygen. In contrast, the amounts of the both gases released were not well correlated with the temperature of the composted manure.
