特晚熟龙眼立冬本果实发育期间对矿质营养需求及其分配的研究结果表明，果实对氮需求的两个高峰期分别在开花期和假种皮迅速生长期；钾的需求高峰期在假种皮迅速生长期；磷的需求相对比较平稳。果实与叶片之间队Ｎ、Ｐ、Ｋ营养的相关性：Ｎ相关不显著，Ｐ达极显著相关，Ｋ为弱负相关。各元素在果实各部组织中的分配：Ｎ在果皮、果核中含量都很高，Ｋ在果肉中占的比例最大，Ｃａ和Ｍｇ大部分在果皮内，Ｐ分布相对比较均匀。 The results of the study on the demand and distribution of mineral nutrition during the development of late-ripening Dahurian winter fruit showed that the two peak periods of fruit demand for nitrogen were at the flowering stage and the aril of rapid growth of seed coat respectively; Rapid growth period; the demand for phosphorus is relatively stable. Correlation of N, P, and K nutrition among the fruit and leaves: N was not significant, P was highly significant, and K was weakly negative. The distribution of each element in the tissues of the fruit: N in the peel, fruit kernels are high, K in the pulp accounted for the largest proportion of most Ca and Mg in the pericarp, P distribution is relatively uniform.
