摘  要：
结合北京市平谷区桃树种植的具体农业生产状况,选用北京市周边具有代表性的鸡粪、金针菇菇渣和桃树枝作为堆肥研究对象,使用实验室堆肥设备进行好氧堆肥,对堆肥产生的氨气排放量及规律进行研究。研究结果表明,堆肥水分从50%增加为60%,氮损失率增加约10%;单位质量堆肥氨气的排放量减少比例与桃枝添加比例成正相关。建议鸡粪与桃枝的比例控制在1∶2.5,堆肥水分控制在50%～60%,以降低堆肥过程中的氨气排放量,减少氮损失。

摘  要：
Based on the agricultural production situation in Beijing,the representative chicken manure,flammulina velutipes mushroom residual and peach branch around Beijing were selected as the research objects of composting,aerobic composting using laboratory composting simulation device was carried out to study the ammonia emission from composting and its regularity.The results showed that,the content of compost moisture increased from 50% to 60%,and the nitrogen loss rate increased by about 10%,the reduction ratio of ammonia emission per unit mass compost was positively correlated with the addition ratio of peach branches.It is suggested that the ratio of chicken manure to peach branches should be controlled at 1∶2.5 and the content of moisture should be controlled at 50% ～ 60% in order to reduce ammonia emission and nitrogen loss during composting.
