青冈无性系基株营养元素的空间格局研究

Studies on Allocation Pattern of Nutritive Element in the Clonal Genets of Cyclobalanopsis Glauca

本研究以C、N、P、K、Ca、Hg、Hn、Cu等营养元素为对象,研究了其在青冈无性系基株各构件中的分配格局。研究结果表明:青冈无性系基株中各构件中营养元素的分配含量符合C>Ca>N>K>Mn>Mg>P>Zn>Cu的规律,多数元素在不同构件中的含量基本符合叶>枝>根>干的分配规律。各构件中多数元素的贮量基本符合干>枝>根>叶的规律,以干中贮量最大。

In this paper, we study the allocation pattern of nine nutrient elements. C、N、P、K、Ca、Mg、Mn、Cu、Zn,in various modules of Cyclobalanopsis's genets. The results show:1)The contents of the nine elements'order is similar,which is C>Ca、N>K>Mn>Mg>P>Zn>Cu. 2)The spatial allocation of most elements is similar, the order is foliar>branch>root>stem. 3)The accumulation of most elements in various modules is stem>branch>root>foliar.
