摘要
为进一步探索微生物发酵床养殖过程中陈化垫料的资源化利用过程,研究了陈化垫料好氧堆肥过程中的温室气体排放以及微生物菌剂的影响。结果表明,在碳氮比合适的情况下,无论添加菌剂与否,陈化垫料均能正常堆肥并达到腐熟要求,添加微生物菌剂可以促进堆肥进程,缩短生产周期。添加微生物菌剂处理的CO2与CH4排放通量均高于空白对照,高温发酵菌剂FC-1(>70℃)处理能降低N2O排放,温室气体总排放率明显低于普通发酵菌剂与空白对照,与空白对照相比,减排率为9.1%。
In order to further study the utilization of spent litters,the greenhouse gas emission during the composition of spent litters in deep-litter system were determined in this paper,and the effects of microbial agents were studied.The results showed that the spent litters in deep-litter system could compost successfully whether using microbial agents or not.But the microbial agents could shorten composting time.The CO2 and CH4emission of spent litters treated by microbial agents were higher than the control,whereas the N2 O emission of high temperature was obviously lower than the others.The total greenhouse gas emission could be reduced by 9.1%treated by FC-1microbial agents compared with the control.
