"菌剂+分子膜"发酵工艺改善秸秆与畜粪共堆肥效率
The"microbial inoculum+molecular membrane"fermentation process to improve the co-composting efficiency of straw and animal manure
摘要
Abstract
To make better use of agricultural waste and improve the nutritional efficiency of com-post products,a novel"microbial inoculum+molecular membrane"fermentation process was used to investigate the physicochemical properties,maturity,humification,and dynamics of phosphorus components in the co-composting process of straw and animal manure.The results demonstrated that the variations in total organic carbon(TOC),moisture content(MC),C/N ratio,and fulvic acid(FA)decreased significantly while the contents of total nitrogen(TN),hu-mic acid(HA),total phosphorus(TP),and available phosphorus(AP)increased significantly(p＜0.05),which indicated that the maturity and nutritional level of co-composted products had been improved.In addition,the humification index and 31P nuclear magnetic resonance(31P-NMR)spectrum analysis revealed an increase in the degree of humification and a change in phos-phorus composition within the compost.In accordance with NY/T 525-2021 regulations,all as-pects of the final compost product meet the required standards except for moisture content.The findings of this study can offer a comprehensive comprehension of the enhancement in composting efficiency through the"microbial inoculum+molecular membrane"fermentation process,and provide a scientific and practical approach for achieving agricultural waste recycling.关键词
