| 摘 要： | 通过对华山松种子园内无性系针叶养分状况的分析，结果表明，无性系之间的营养元素含量差异极显著，尤其表现在Ｃａ，Ｋ营养上，而针叶的元素含量顺序为Ｎ，Ｃａ，Ｋ，Ｍｇ，Ｐ，Ｍｎ，Ｆｅ，Ｚｎ，Ｂ；不同月龄针叶养分含量差异极大，未完全抽长针叶养分含量顺序为Ｎ，Ｋ，Ｃａ，Ｍｇ，Ｐ。针叶内微量元素含量与无性系有较大相关性，而不同土壤上华山松针叶微量元素的含量差异更大，尤其是针叶Ｂ的含量，因此土壤施Ｂ可在针叶的含量 |

| Abstract: | There was a significant difference of the element contents among different Pinus armandi clones, especially the contents of Ca and K.The order of the leaf element contents was N,Ca,K,Mg,P,Mn,Fe,Zn,B. The element contents of different aged leaves were greatly different. In undeveloped leaves the order of element contents was N,K,Ca,Mg,P. Different clones had quite different microelement contents in the leaves.Leaf microelement contents varied with different soils, especially the content of B.Thus,the application of B could increase the content of leaf B. |
