定期测定短枝型和普通型苹果叶和果中氮、磷、钾和粗蛋白含量表明，生长期内诸元素含量均随叶龄的增大和果实的发育而降低；试验获得短枝型与普通型叶、果中氮、磷、钾和粗蛋白含量的比较分析资料，统计结果显示，无论生长前期或后期，各短枝型品种叶、果中诸元素含量均较普通型品种为高，差异均达显著或极显著水平。
The determination of nitrogen, phosphorus, potassium and crude protein content in the leaves and fruits of spur and normal apples on a regular basis showed that the contents of all elements decreased with the increase of leaf age and fruit development during the growth period. Type leaves, fruits of nitrogen, phosphorus, potassium and crude protein content of the comparative analysis of the data, the statistical results show that regardless of the growth of early or late, the sprout varieties of leaves, fruits of the elements were higher than the average type, the difference All reached significant or very significant levels.
