Abstract:
Taking 10 common garden tree species as test materials,the litter natural decomposition experiment was carried out by using litter decomposition net bag method,and the litter decomposition rate and nutrient release were studied,in order to provide reference for scientific management and protection of urban garden tree species and optimization of urban green space function.The results showed that,1) The litter decomposition rates of the 10 species were as follow,poplar>pomegranate>crape myrtle>coralpark>spring elm>sycamore>wintersweet>honey locust>paulownia>red maple.2) In the process of litter decomposition,the organic C and total N release rates were faster in poplar,pomegranate and crape myrtle,while the total P released faster in crape myrtle,poplar and spring elm.No significant differences of cellulose decomposition rate were found in the 10 tree species.Lignin decomposes slowly,while hemicellulose decomposes faster in spring elm,poplar and pomegranate.3)The litter decomposition rate significantly declined with the increase of litter initial concentration of organic C and total N,and the litter N/P ratio,while presented no significant correlations to litter C/N ratio,lignin/N ratio and lignin concentration.
