摘　　要：对梨枣和骏枣叶片中的七种矿质营养元素(K、Ca、Mg、Fe、Mn、Cu、Zn)含量的年周期变化进行了研究。结果表明,不同品种枣树叶片矿质营养元素含量差异显著,但元素含量在生长季的波动规律基本相同；试验显示,枣叶分析适宜采样时期为8月份；相关分析表明,各元素问存在一定相关性。试验结果为枣树的丰产、优质栽培和科学的配方施肥提供了依据。This paper studied the mineral nutrition （K, Ca, Mg, Cu, Fe, Mn, Zn） in leaves of jun-jujube trees and pearjujube trees in a year. The results were as follows., the difference of mineral contentin different variety jujube leaves is significant, but the law of nutrition content fluctuation is constant during the period of growth; The results indicate that The change of the contents of the mineral nutritions is stable in August, so its leaves could be picked for analysis. At the same time, there is a strong correlation in different factors. The study provide new theoretical evidence for high yield and high quality cultivation and the physiology of resistance of the jujube trees.
