主 题：Green waste Earthworms Sugarcane bagasse Vermicomposting Nutrient recovery
摘 要：Vermicomposting is a feasible method for disposing of lignocellulosic waste while generating a useful *** current study assessed the potential of vermicomposting green waste mixed with sugarcane bagasse in proportions of 25%,50%,and 75%(v:v,based on dry weight).The suitability was evaluated based on the agrochemical properties,earthworm biomass,and *** final vermicomposts exhibited near-neutral pH values(7.1-7.6),and lower EC values(0.43-0.72 mS/cm)and C:N ratios(14.1-19.9).The content of available nutrients and CEC for all the vermicomposts exceeded those of the control compost(without earthworms).For vermicomposts,the average values of NO3-N,AP,AK,and CEC were 53,517,1362 mg/kg,and 158 cmol/kg,*** total contents of heavy metals increased in all vermicompost treatments compared to control composts with the following average final percentages:Zn(2.0%),Cr(15.5%),Pb(23.4%),and Cu(44.3%),but these amounts were safe for application in *** addition of sugarcane bagasse to green waste significantly increased the content of total humic substance,humic acid and urease activity,acid and alkaline phosphatase activity,and Eisenia fetida *** addition of 25%sugarcane bagasse to green waste decreased the toxicity to germinating *** results revealed that vermicomposting is a feasible way to degrade green waste into a value-added chemical product.
