笔者以10年生壶瓶枣树为试材，研究了枣果生长期内枣园土壤营养成分含量的变化。结果表明，随着枣果的生长发育，干旱碱性土壤中有机质、全氮、速效钾、全磷、有效铜、有效锰、交互性镁的含量减少，有效锌含量保持相对的稳定，交互性钙含量在不断升高；枣果生长中期（9月上旬）土壤有机质、速效钾、全磷、全氮、有效铜、有效锌、交互性镁的含量，在40 cm土层中存在增加的现象。

Ten year-old Huping Jujube as material , nutrient content change in soil during the growth period of jujube fruit was studied.The main results were as follows,in the dry and alkaline soils,the content of soil organic matter, potassium, total phosphorus, total nitrogen, available Cu, available Zn, exchangeable Mg decreased;available Zn content remained relatively stable, exchangeable Ca content rised with the growth of jujube fruit;on 40 cm soil layer, organic matter, AK, TP, TN, a-vailable Cu, available Zn, exchangeable Mg content increased in metaphase of jujube growth (early September).
