|a Appropriate stocking density plays an important role in ensuring the stability and improving the overall efficiency of the vermicomposting system. Although some studies have shown that earthworms can degrade lignocellulosic materials, relatively few studies have been conducted on the effect of earthworm stocking density on the degradation of a single green waste (GW) with high lignocellulosic content. Therefore, this study investigated the degradation effect of earthworms on GW at different stocking densities, and assessed the stability and maturity of the whole vermicomposting by comprehensively analysing the changes in physicochemical and biological properties of earthworms during vermicomposting, and by combining the growth of earthworms with a multi-dimensional assessment of the stability and maturity of the whole vermicomposting. In this study, six stocking densities (CK-T5) were set up, namely, no earthworms, 10, 20, 30, 40, and 50 worms/kg. The results showed that compared with the CK (without earthworms), when there were 30 earthworms per kg of GW (i.e. T3), the total nitrogen, total phosphorus, total potassium, organic matter decomposition, bacterial and fungal numbers, and germination index of earthworm compost products increased by 14 %, 29 %, 32 %, 35 %, 42 %, 94 %, and 125 %, respectively. T3 also enhanced the activities of cellulase and alkaline phosphatase. The results were further supported by principal component analysis. Finally, we conclude that when the stocking density of earthworms is appropriate (T3), it not only favours the growth of earthworms, but also positively affects the physicochemical properties of the vermicomposting process, which in turn significantly improves the biodegradation efficiency of GW
