| 摘 要： | 氨挥发是堆肥发酵过程中,臭味产生和氮素损失的主要原因。以鸡粪为原料进行堆肥发酵,通过添加除臭菌剂和相关填充物料,有效控制堆肥发酵过程中氨的挥发,以减少氮素的损失。研究结果表明：除臭菌剂和填充物料的加入能有效降低发酵过程中氨的挥发损失,缩短发酵脱臭的时间。与对照处理相比,除臭菌剂能够提前10 d左右消除臭味,糠醛渣可减少氮素损失达17.6%以上。

| Abstract: | Ammonia volatilization was the main reason of nitrogen loss and stench arising in poultry composting process.In this experiment,deodorizing microorganism and compost filler were added in poultry composting process in order to control nitrogen volatilization,as fowl dung was taken for the raw material.The results were showed that the treatment of addition deodorizing microorganism and compost filler could effectively reduce nitrogen volatilization efficiency,significantly shorten the fermentation deodorization time.Compared with the CK treatment,the stench could be eliminated before 10 days by adding deodorizing microorganism,furfural residue could reduce about 17.6% nitrogen loss. |
