Change of Macronutrient Content in Fruit Growing Stage of Camellia oleifera

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 tendency of “drops-rises-drops”. The content of K in fruits kept increasing during the period of fruits growth.
