摘    要:腐殖质是评价堆肥品质的重要因素,该文利用鸡粪和秸秆为原料进行高温好氧堆肥,设计接种菌剂和不接种菌剂(对照)2个处理,研究菌剂添加对堆肥腐殖质形态、含量、品质的影响。结果表明:与对照相比,接种菌剂可以加快有机物的降解,矿质化时间缩短14d,菌剂具有良好的保碳效果,总有机碳含量提高了16.1%,同时总腐殖酸、游离腐殖酸以及水溶态腐殖酸及胡敏酸的含量,分别提高了38.7%,45.7%、39.0%及54.9%。接种菌剂可以提高腐殖酸的活性,堆肥结束后,接种菌剂处理的游离腐殖酸和水溶性腐殖酸含量均增加,而对照处理的含量均降低;堆肥可以提高腐殖酸质量,堆肥结束后两个处理总腐殖酸含量均下降但是缩合度、腐殖化率、腐殖化指数及胡敏酸百分比均提高,特别是添加菌剂的处理腐殖化程度明显高于对照。说明了菌剂可以增加堆肥腐殖质含量,提高腐殖质缩合度、芳构化程度及活性。

关 键 词:堆肥    有机碳  腐殖质组成  腐殖质品质  菌剂

Abstract:The aim of this study was to investigate the influence of inoculation on the humification (composition, content and quality) in aerobic composting of chicken manure.Two treatments with three replicates were conductedto achieve the object. The “VT-1000”microbial agent (produced by Beijing VOTO Biotechnology Corporation Limited) was used in composting with the amount of 3‰ of initial raw materials (based on wet weight). A control treatment (CK) was also studied without inoculants. Both of the two treatments had the same C/N ratio (15), moisture content (65%) at the beginning of the composting. The research was conducted in 2m×1.5m×1m(length×width×height) windows using static fermentationcomposting system with natural ventilation for a period of 53 days in total. During the experiment the content of total organic carbon (TOC), total humus (HS), free humus (FHS), water-soluble humus (WSHS), humic acid (HA), fulvic acid (FA) and E4/E6were determined, and some other polymerization and humification indices such as humification ratio (HR), humification index (HI), ratio of humic acid to fulvic acid (HA/FA), percentage of humic acid (PHA) were also studied. Results showed that inoculants significantly affected the humification. Microbial agent could significantly accelerate the organic matter degradation speed and shorten the mineralization phase for about 14 days compared with the CK. Composting with inoculants showed a significant effect on carbon conservation.The TOC of product in inoculated treatment was 16.1% higher than in CK. At the same time, composting with inoculants could elevate the contents of HS by 38.7%, and it also increased FHS, WSHS and HA by 45.7%, 39.0% and 54.9%, respectively.The content of FHS and WSHS decreased in CK after composting, while this trend was converted to increasein inoculated treatment. So the activity part of humus improved with the addition of microbialagent. Despite the content of HS decreased, the HR, HI, HA/FA and PHA were all increased at the end of composting especially in the composting with microbial agent, indicating that composting can improve the humus quality. HA/FA was higher in inoculated treatment than in CK which indicated that inoculants can accelerate the compost maturity. The E4/E6 value in the microbial agent treatment was lower than that in the CK treatment, which indicated that adding microbial agent enhanced the extent of humification and aromatization in the compost. In conclusion, inoculants could shorten the composting time, increase the content of humus and enhanced the extent of humification and aromatization in the compost.
Keywords:composting  manures  organic carbon  humus composition  humus quality  microbial agent
