摘　　要：好氧堆肥是实现鸡粪资源化处理最主要的技术手段之一。然而在鸡粪堆肥过程中氮素损失较为严重,在降低肥效的同时,还引起严重的面源污染。本文总结影响鸡粪堆肥过程氮素损失的主要原因,并综述初始C/N、初始含水率、翻堆频率、添加剂种类对鸡粪堆肥过程氮素损失的影响,得出减少鸡粪堆肥氮素损失的最适初始C/N为20~25、初始含水率为60%~65%、翻堆频率为7天1次。复合添加剂较单一添加剂更能降低堆肥过程中的氮素损失。最后提出鸡粪堆肥未来方向的研究展望,为今后进行鸡粪堆肥过程中氮素损失的研究提供理论依据。Aerobic composting is one of the main technical methods to achieve the resource utilization of chicken manure.However,nitrogen loss is serious during chicken manure composting,which not only reduces the fertilizer efficiency,but also causes severe non-point source pollution.This paper summarizes the main causes of nitrogen loss during chicken manure composting,and reviews the effects of initial C/N,initial moisture content,turning frequency,and additive types on nitrogen loss during chicken manure composting.It is concluded that the optimal initial C/N,initial moisture content,and turning frequency for reducing nitrogen loss during chicken manure composting are 20-25,60%-65%,and once/7d,respectively.Compound additives can reduce nitrogen loss during composting more than single additives.Finally,the future research prospects of chicken manure composting are proposed.This paper provides a theoretical basis for the study of nitrogen loss during chicken manure composting.
