Abstract:
The nutrition and mineral elements in leaves of Pistacia chinensis in area of Nanquan and Beibei were determined and analyzed，the different periods changes of mineral elements of the wild Pistacia chinensis all the year round were studied.The results showed that matures’ mineral elements generally changed trend that N，P，K decreased，Fe，Ca had generally increased，and Mg，Zn were fluctuation.According to the pot fertilization experiment researched as well as the variation difference analysis of matures，could be inferred that different soil conditions，different ages，different cultivation and management would affect the contents of mineral elements in leaves of Pistacia chinensis.Through reasonable fertilization to supply the Pistacia chinensis N，P，K elements，ensured N，P，K elements adequately，promoted new shoot growth，and improved the quality of flower bud differentiation.
