| 摘 要： | 在较高营养水平的栽培条件下，研究了三年生水仙各营养器官在生长期中氮、磷、钾含量的动态变化。结果表明：水仙的不同营养器官氮、磷、钾的变化速率和总量的差异极为明显。植株体内氮的递增速率在生长中、后期较快，而在生长前、末期较慢；磷的递增速率在生长后期最快；钾的递增速率在整个生长期中变化较小。每株水仙在整个生长期中氮、磷、钾的净增量分别为３６６．１７，１９．８０，４４５．１２ｍｇ。

| Abstract: | Nitrogen,Phosphorous and Potassium content is determined and their trend changes have been studied (in nutritive organs of triennial narcissus) under a sufficient nutrient condition.The deta obtained show that the change rates and total content of N,P and K differ greatly in different nutritive organs of narcissus.The net increase rate of N is faster during metaphase and anaphase than that during prophase and telophase in the growth of narcissus;the net increase rate of P tops the highest level during anaphase;and that of K varies slightly in the whole growth.The net increases of N,P and K in narcissus plant are 366.17,19.80,445.12 mg respectively. |
