| 摘 要： | 为了解黄金梨叶片和果实中各种矿质养分含量变化规律及相关关系,对黄金梨生育期叶片和果实中矿质元素含量的年变化进行了研究,结果表明:叶片内N、P、K含量随叶龄增加而降低,Ca含量随叶龄增加而升高,Mg含量前期增加,后期减少;果实中N、P、K、Ca、Mg含量随果实膨大而呈递减趋势。叶片和果实中Mn、Cu含量均呈递减趋势,而Fe、Zn含量变化波动较大。经相关分析表明叶片和果实中矿质营养元素间存在一定的相关性。

| Abstract: | This paper reported the seasonal changes of nine mineral element contents in the leaves and fruits of Whangkeumbae. The results showed that the contents of N, P, K in the leaves manifested a decreasing tendency in a year, the content of Ca showed increasing tendency, the content of Mg increasing in early period, decreasing in late period. The content of N, P, K, Ca, Mg in fruits manifested a decreasing tendency from setting fruit to harvesting. The contents of Mn and Cu in leaves and fruits showed a decreasing tendency. But Fe, Zn contents changed largely. The mineral elements in fruits and leaves have some correlations. |
