| 中文摘要: |
| 为研究餐厨有机浆液厌氧沼渣与黑水虻虫粪共堆肥的效果，本研究设计5组混合比（沼渣∶虫粪）：T1（4∶0）、T2（3∶1）、T3（1∶1）、T4（1∶3）和T5（0∶4），进行了为期30 d的堆肥实验。结果表明：与T1相比，T2、T3、T4和T5的硝态氮含量分别提高了72.63%、77.93%、88.69%和85.99%。T2处理组堆料具有最高的有机质降解率（13.80%），堆肥产品具有较高的腐殖质含量（107.55 g·kg-1）、胡敏酸含量（79.20 g·kg-1）和胡富比（2.79）。堆肥30 d后，各处理组种子发芽指数均超过80%，其中T1~T4处理组超过100%。随着虫粪比例的增加，堆料电导率显著升高（P<0.05）。研究表明，添加虫粪可加强固氮作用、提高堆肥产品肥效，同时共堆肥可提高有机质降解率、强化腐殖化进程，但是过量虫粪会增加堆料盐度，对植物生长有一定影响，综合效果显示，沼渣和虫粪配比为3∶1时堆肥效果最佳。 |

| The effects of co-composting biogas residue of kitchen organic slurry（BR）and black soldier fly larval frass（LF）were investigated in this study. Five mixing ratios（BR∶LF）were designed：T1（4∶0）, T2（3∶1）, T3（1∶1）, T4（1∶3）, and T5（0∶4）. Composting experiments were conducted for 30 days. The results demonstrated that compared with the nitrate nitrogen content in T1, it increased by 72.63%, 77.93%, 88.69%, and 85.99% in T2, T3, T4, and T5, respectively. In addition, the highest organic matter degradation rate, humic substance content, humic acid content and HA/FA were obtained in the T2 treatment with values of 13.80%, 107.55 g·kg-1, 79.20 g·kg-1 and 2.79, respectively. After 30 days of composting, the seed germination index of each treatment group exceeded 80%, of which T1~T4 exceeded 100%. However, the electrical conductivity of the composting product increased significantly with an increase in LF（P<0.05）. The results indicate that the addition of LF can strengthen nitrogen fixation and improve the fertilizer efficiency of composting products. Meanwhile, co-composting can improve the organic matter degradation rate and enhance the humification process. Nevertheless, excessive LF increases the salinity of composting, and thus, produces a certain negative influence on plant growth. A comprehensive comparison of all indicators revealed that the optimal composting group was obtained when the BR∶LF ratio was 3∶1. |
