| 摘 要： | 为了揭示不同年龄红松(Pinus koraiensis)叶片和树枝中各种元素质量分数的差异,选择红松1～3年生树枝和叶片进行N、P、K、Mg、Zn、Mn、Ca、Cu和Fe的质量分数测定,并进行相关分析.结果表明:树枝中的N、P、K、Mg、Zn、Mn质量分数随枝龄的增大而减小,Ca、Cu和Fe质量分数随枝龄的增大而升高....

| Abstract: | An experiment was conducted to study the correlations between element contents in 1 to 3-year-old branches and leaves of adult Korean pines(Pinus koraiensis) by measuring contents of N,P,K,Mg,Zn,Mn,Ca,Cu and Fe,aiming to approach the difference in element contents in different aged leaves and branches.Result showed that N,P,K,Mg,Zn and Mn in the branches decreased with age,while Ca,Cu and Fe showed a contrary tendency.However,P and K in the leaves decreased with age,and Ca,Mg,Fe and Mn increased with leaf a... |
