鸡粪堆肥过程中的氮素转化及损失控制

Nitrogen Transformation and Loss Control in Composting of Chicken Manure

对鸡粪好氧堆肥过程中氮素的各种存在形态进行研究,发现在堆肥的不同阶段中氮素的主要存在形式,研究氮素损失的主要途径。通过实验,发现氨气是氮素损失的主要形式,占总氮素损失的50%以上,寻找减少氨气排放的方案,就可以减少氮素损失,使更多的氮素固定到堆体中。

This paper studies the form of nitrogen in compost of chicken manure,found the form of nitrogen in different stages and researched the main way to reduce the nitrogen loss.Through the experiment,we found that the ammonia is the main form of nitrogen loss,the total loss of nitrogen is more than 50%. The nitrogen loss can be reduced if the way can be found. In the end,more nitrogen will be fixed in the chicken manure.
