Study on screening of combination microbial agents on aerobic composting fermentation of cow dung
In order to screen out the combination of microbial agents with good effect in aerobic composting fermentation of cow dung,the study carried out the experiment of aerobic composting fermentation of cow dung by taking Bacillus glialis,Streptomyces flavus,Nitrogen fixing bacteria and Aspergillus niger which were compatible with different combinations.The results showed that the 0.2%combination of Bacillus glialis+Streptomyces flavus+Nitrogen fixing bacteria+Aspergillus niger 1∶1∶1∶1 had the best effect on the fermentation of cow manure aerobic composting.The pile temperature was fast,the temperature was high,the high temperature duration was long,the water content after composting was low,the organic matter and C/N decreased greatly,the total nitrogen、total potassium and total phosphorus contents increased,and the pH and seed germination index were high.It can be popularized and applied in the fermentation of cow manure aerobic composting.
