Abstract:
Taking peony trees which were about 8-year-old as material，the character of biomass composition，mineral element content and its accumulation in different parts of peony trees were analyzed，in order to investigate the properties of accumulation and distribution of mineral elements in peony and to establish a reasonable fertilization protocol.The results showed that the nutrient content and the annual of biomass of 8-year-old ‘Xiaohuhong’ in ground part were N 4.29，P2O5 0.50, K2O 1.46, Ca 7.82, Mg 0.97 g/plant；Mn 8.21, Cu 11.56，Fe 149.25 mg/plant. the N, P2O5, K2O content in leaf，development shoot and root reached the highest level in March，the second highest level in April.Nitrogen was mainly assigned to the leaf，bud and fruit，P2O5 and K2O were mainly assigned to the fruit and leaf，Ca and Mg were mainly assigned to the leaf and development shoot，while Mn，Cu and Fe were mainly assigned to the fruit and leaf.
