摘要
比较了在同一立地条件下生长年龄、砧木完全一致的苹果短枝型品种和普通型品种的营养特性。结果表明：（１）短枝型品种地上部的Ｎ素营养、碳素营养明显高于普通型品种，地下部根系的营养含量相反；（２）短枝型品种耐肥性较高；（３）两类品种对铵态氮和硝态氮肥的田间反应存在差异。
Starkrimson and starking apple trees of the same age and rootstock were used as experimental materialsand planted in the same field conditions. The results of the study on the nutritional characters showed thespurtype apple Starkrimson has more nutrition content in leaves,but less in roots.The ability of fertilizer-en-during of the spur-type apple tree is higher; moreover the reaction to different kinds of nitrogen source be-tween the two cultivars is not the same.
