摘要: 利用通风式堆肥发酵方式研究了牛粪堆制过程中氨气的挥发特征和锯末、稻壳、稻草等不同水分调节材料对氨气挥发的影响。结果表明,牛粪堆制过程中主要在前期,尤其是在最初的2周内释放氨气;堆肥期间挥发的氨态氮约为牛粪总含氮量的17%~50%。不同水分调节材料都可以在一定程度上抑制氨气的挥发,但锯末抑制氨气挥发效果最好,其次是稻壳,稻草抑制氨气挥发的效果较小。因此,为了减少氮素损失,应采取适当措施抑制氨挥发或回收挥发的氨气。

Abstract: Emission of ammonia during composting of dairy cattle waste and effects of organic materials added to adjust moisture content of the compost on loss of ammonia were studied.Results indicated that the emission of ammonia concentrated mainly in the early stage of composting,especially in the first 2 weeks,and the total N loss during the composting period was about 17%~50% of the total N in the dairy cattle waste.Addition of moisture regulating materials could reduce the N loss in varying degrees during composting.Sawdust showed the best restraining effect on ammonia emission,followed by rice hull and rice straw.Therefore,some steps should be taken to prevent the N lose.

Key words: dairy cattle waste, composting, emission of ammonia, moisture regulating material, sawdust, rice hull, rice straw
