| 中文摘要 |
| 为了综合评估蚯蚓堆肥在不同控制条件下堆肥质量和重金属的转化规律,综述了109篇文献,通过Meta分析定量探讨了蚯蚓种类、预堆肥时间、通风方式、初始C/N、初始pH和初始含水率对提高蚯蚓堆肥质量和降低重金属毒性方面的影响.结果表明,以上6分组因子均显著影响堆肥的质量和重金属毒性.经过蚯蚓堆肥后,以下营养指标含量显著增加：NO3--N（116.2%）、TN（29.1%）、TP（31.2%）和TK（15.0%）；而NH4+-N含量（-14.8%）和C/N（-36.3%）显著降低；同时也显著降低了最终堆肥中Cu和Cr总量及其生物有效性.综合考虑不同分组因子对堆肥质量和重金属影响的显著程度,若堆肥以促进腐熟和富集营养元素为目的,则建议堆体物料的初始含水率调节为70%~80%、C/N为30~85和pH为6~7,并进行0~15 d的预堆肥,通风方式采用自然放置方法；若以削弱物料中重金属危害为主要目的,则建议调节物料初始含水率为50%~60%、C/N小于30和pH为7~8,不进行预堆肥,定时翻堆,引用Eudrilus eugeniae种类进行蚯蚓堆肥. |
| 英文摘要 |
| In order to comprehensively evaluate the effects of vermicomposting on compost quality and the conversion of heavy metals under different control conditions, 109 studies were reviewed. The effects of earthworm species, pre-compost time, ventilation methods, initial C/N, initial pH, and initial moisture of the raw materials on compost quality and the heavy metal toxicity were quantitatively discussed during the vermicomposting process through Meta-analysis. The results showed that the six subgroups of factors all showed obvious influences on the compost quality and heavy metal toxicity. After vermicomposting, the contents of NO3--N (116.2%), TN (29.1%), TP (31.2%), and TK (15.0%) were significantly increased, whereas NH4+-N (-14.8%) and C/N (-36.3%) were significantly decreased. Meanwhile, the total amount of Cu and Cr of the final compost and their bioavailability were significantly reduced. Considering the influences of grouping factors on compost quality and heavy metals, it is recommended to adjust the initial moisture of pile materials to 70%-80%, C/N to 30-85, and pH to 6-7 and to conduct pre-composting for 0-15 d; additionally, vermicomposting should be naturally placed when the composting is aimed at promoting the compost quality. If the main purpose is to weaken the perniciousness of heavy metals in the raw material, it is recommended to adjust the initial moisture of the material to 50%-60%, C/N to less than 30, and pH to 7-8; to conduct no pre-compost; regularly turn the piles; and use the earthworm Eudrilus eugeniae for vermicomposting. |
