低温型复合发酵菌剂接种鸡粪堆肥的效应
Fermentation effects of chicken manure inoculating with compound inoculants of low temperature character
摘要
Abstract
With fresh chicken manure as the main material,a compost fermentation test was carried out in a low temperature environment with a cold start using composite fermentation inoculants.The dynamics of composting temperature,moisture,pH value,C/N,ash content,NH4+-N,and organic matter content were analyzed during the fermentation process.Results showed that the inoculants initiated fermentation within 24 h at 15 ℃,which was 2 d earlier in comparison with the control.As a result,the experimental compost temperature reached 50 ℃ 5 d earlier and continued to be over 55 ℃ throughout the 14 d period.This rapid fermentation accelerated water volatilization and reduced the ratio of C/N.The seed germination index reached 80.4％ after 15 d fermentation.This was 12 d earlier than the control.Though the process caused a slightly higher loss of organic matter,the total nitrogen loss was reduced while ammonium nitrogen content increased by 70.2％,thus indicating a remarkable nitrogen preserving effect.关键词
