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. © 2024 Science Press.
