摘　　要：试验测定了山西省有代表性的杏幼树、成龄树叶片中营养元素的含量及对应的杏园土壤营养元素含量。并对幼树种类间、成龄杏树不同主产区之间叶元素含量的差别进行了显著性测验，对成龄杏园土壤与叶片间元素含量作了相关分析。同时研究了其Ｃａ／Ｍｇ，Ｍｎ／Ｆｅ值。结果表明，杏幼树嫁接口有调节镁元素通过的作用。对山西杏叶营养作了全面测定，提出了杏叶营养元素含量的参考指标。In this paper, it was determined the contents of N, P, K, Ca, Mg, Zn, Fe, Mn and Cu in the leaves of both young and adult apricot trees, and the contents of N, P, K, Zn, Fe, Mn, Cu in the soil of the same orchard. Significance tests were done on element contents in different varieties of young and adult trees at different regions in Shanxi province. Correlation analysis was done between leaves' and soil's element contents in adult's orchard. The results showed that graft union could affect the pass of Mg in young apricot trees. Through determining the elements' contents of apricot trees in main areas of Shanxi province, the reference value of elements was given.
