摘要
在不同立地营养胁迫下对２０年生杉木各器官Ｎ、Ｐ、Ｋ元素变化进行分析，结果表明各器官Ｎ、Ｐ元素随立地营养胁迫加深而下降率增大，Ｋ元素则相反。而且各器官这些元素的变化程度不一。
Under the nutrient stress of different sites,the changes of N,P and K elements in various organs of twenty year old Cunninghamia lanceolata were analyzed.The results indicated that the reductive rate of N and P elements in various organs increased with the deepening of site nutrient stress whereas the situation of K element was opposite.
