摘　　要：应用营养元素在树体内的移动原理,比较同一新梢不同部位叶片营养元素含量的差异,判断营养元素是否发生迁移,进而诊断营养的丰缺状况。通过对10多个生产园的取样分析,对这一诊断方法的可行性进行了初步探索。结果表明,对易流动营养元素来说,此法有较好的适用性。In accordance with the principles of nutrient element movement in trees, the new method is carried out with comparing the content difference of several nutrient elements in different leaves of a branch,and determines the moving state of these nutrient elements in trees, and then the nutrient status will be diagnosed. The feasibility of this method has been proved by analyzing the leaf samples collected from more than ten orchards. It is believed that this new diagnostic method is good for some easy movable nutrient elements.
