为了生产出具有较高农艺价值的堆肥，研究了不同菌群和不同翻堆频率对城市生活垃圾有机组分堆肥的影响。制备了四堆OFMSW：三堆接种有真菌聚生体，其含有5升绿色木霉、尼日尔曲霉和黄曲霉的孢子悬浮液，并且转动频率为每周（堆1）、每周两次（堆2）和每天（堆3），而每周转动且不接种真菌的堆4作为对照。每周（桩1）转向频率的真菌财团显着影响温度，pH值，TOC，TKN，C/N比和发芽指数。在1号堆中观察到有机物的高度降解和早熟。结果表明，真菌财团与每周的开放式料堆的转动频率是更具有成本效益的高效堆肥和产量安全的最终产品相比，与其他技术。(C)2014爱思唯尔有限公司版权所有。
Influence of fungal consortium and different turning frequency on composting of organic fraction of municipal solid waste (OFMSW) was investigated to produce compost with higher agronomic value. Four piles of OFMSW were prepared: three piles were inoculated with fungal consortium containing 5 l each spore suspensions of Trichoderma viride, Aspergillus niger and Aspergillus flavus and with a turning frequency of weekly (Pile 1), twice a week (Pile 2) and daily (Pile 3), while Pile 4 with weekly turning and without fungal inoculation served as control. The fungal consortium with weekly (Pile 1) turning frequency significantly affected temperature, pH, TOC, TKN, C/N ratio and germination index. High degradation of organic matter and early maturity was observed in Pile 1. Results indicate that fungal consortium with weekly turning frequency of open windrows were more cost-effective in comparison with other technologies for efficient composting and yield safe end products.
