摘要： 研究表明,红星苹果树在年周期内各器官营养元素的含量变动很大,不同砧穗组合也有一定差异.矮化中间砧树叶片、果实和发育枝内多数营养元素含量高于乔砧树.红星苹果产量与叶内氮、磷的含量呈正相关,而与叶内钾的含量呈负相关.文中还讨论了营养元素在器官间存在的相关性.

Abstract: The research results showed that the contents of the nutrient elements in every organs of Red Starking apple tree changed largely in one year, the contents of those elements in various stock-secion were also different, The contents of the most nutrient elements in the leaves,fruits and extensive shoots of the dwarfing interstem apple trees were higher than those in the vigorous rootstock apple trees.The studies demonstrated that the output of Red Star king apple tree had positive correlation with the contents of nitrogen and phosphorus in the leaves，but it had negative correlation with the content of kalium in the leaves.The correlation among the nutrient contents of the organs were also discu ssed in this paper。
