| 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。

| Abstract: | This paper studied the mineral nutrition (K、Ca、Mg、Cu、Fe、Mn、Zn) in leaves of jun-jujube trees and pear- jujube trees in a year.The results were as follows:the difference of mineral contentin different variety jujube leaves is sig- nificant,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. |
