Abstract

Abstract

Potted seedlings of Eucalyptus urophyllaE.grandis DH32-29 were used to study the effect of the coating,sulfate, steam,or active fertilizations on the soil and the carbon (C),nitrogen (N),and phosphorus (P)contents as well as stoichiometric characteristics of the leaves of the plants. The results showed that (1) all fertilization scould significantly increase C, N, and P in the soil and the leaves; (2) C in soil and C, N, and P in leaves were higher by using active fertilization in the soil than those 3 other treatments, while N and P in the soil were less with the active fertilization than without; (3)the ratios of C:N and C:P in soil were significantly lower with the fertilizations than control without added fertilizer; (4) C:N in leaves was significantly lower with fertilization than control, and N:P significantly higher than control, while the ratios of C:N and N:P in leaves were similar among the different fertilizations but lower than control; (5) a weak inverse correlationship was oberved between C and P contents in the potting soil; (6)the C, N, and C, N, P stoichiometric ratio in soil did not correlate tothe C, N, P, and stoichiometric ratio in leaves, but in the soil,N significantly correlated with C:N; (7)highly significant correlations between the N, P, C:N, C:P, N:P in soil and the C, N, P, and stoichiometry in leaves were found.
