摘要：In order to explore the application effect ofadvanced anaerobic digestibility sludge on forestland in recent years and fill in the blank of forestryapplication research,this study aimed to explore thechange of heavy metal morphology in soil and itsinfluencingfactors under different amounts ofsludge application and woody plants-mulberry(Morus alba L.) plantation,concentrations of 0%(CK),6.25%,12.5%,25%,50%,75%and 100%( volume ratio） sludge were combined with soil.The results showed that mulberry could germinateand grow normally in the sludge,and the growthindexes of mulberry were higher than CKat25%-50%concentration.Applying advanced an-aerobic digesting sludge can significantly increasesoil nutrients,and the nutrient content of the sludgeand the physicochemical action of the woody plantchanged the pH,CEC and organic matter of the soil,thereby promote the reduction of the residual stateand the migration and transformation of the effec-tive heavy metals.Our findings indicate that mul-berry can be used as a super-enriched plant with avariety of heavy metals and the optimal applicationrate is less than 25%.
