| Abstract: | In order to explore ecological stoichiometric characteristics of carbon(C),nitrogen(N)and phosphorus(P)as well as its response to environmental factors in the suitable area of Mangifera persiciformis growth in Guangxi,China,the soil total carbon(SOC),total N,total P and environmental factors in suitable growth areas such as Nanning and Baise in Guangxi were studied by field investigation and indoor analysis.The results showed that the mineralization of organic matter were slow.However,soil P showed a net mineralization,which had high availability.The ratio of soil C︰P and N︰P is mainly affected by total P content.The results from redundancy analysis showed that the first two axes explained 84.94%of the variability of C︰N︰P stoichiometry.The rank of explanation rate were altitude>pH>annual average temperature>annual average rainfall.Altitude and soil pH had significant effects on C︰N︰P stoichiometry. |
