在果实生长发育阶段，以油茶果实和叶片为试材，分析测定 N、P、K 含量的变化规律。结果表明：叶片和果实中 N 的含量随时间推移不断下降；果实中 P 的含量在果实迅速生长期不断上升，在油脂合成阶段不断下降，叶片中 P 含量变化规律与果实基本一致；叶片中 K 含量呈现出“降—升—降”的规律，果实中 K 含量随果实膨大始终保持逐步上升的趋势。

In order to find out change law of the content of N (nitrogen),P(phosphorus)and K (Potassium) in leafs and fruits in fruit-growing stage of Camellia oleifera.The results showed that content of N in leafs and fruits decreased gradually along with the time.The content of P in fruits increased during the fruit rapid growth period, while decreased during the period of synthesis of lipid.The content of P in leafs change present the variation tend-ency of “drops -rises -drops”.The content of K in fruits kept increasing during the period of fruits growth.
