研究鼎湖山南亚热带季风常绿阔叶林黄果厚壳桂群落元素含量特征 ,分析了其中 9个种不同器官的 6种元素含量 ,结果表明 :1 )群落中植物不同器官的元素含量大小为 ,N:叶 >皮 >根 >枝 >茎 ,P:叶 >枝、皮 >根 >茎 ,K:叶 >皮 >枝 >根 >茎 ,Ca:皮 >叶 >枝 >根 >,Mg:叶 >皮 >根 >枝 >茎。 2 )椎栗、黄果厚壳桂、鼎湖钓樟和双盖蕨是群落中含 N量较高的种 ;椎栗、云南银柴和双盖蕨含 P量较高 ;各个种的含 K量相似。 3)养分含量表现出一定的层次性差异 ,上层种叶子含 P量高于下层种 ,但含 K量区别不显著。上层种茎 N、P、K含量显著低于下层种。黄果厚壳桂种群 ,其不同层次个体养分含量没有统计上的显著差异 ,但下层个体茎养分高 ,上层个体茎养分低。 4)群落不同元素间具有许多显著相关的元素对 ,其中 N与其它元素的相关性最大 ,其次是 Mg、P,再次是 K,而 Na不与其它任何元素相关 ,Ca相关性很少。从器官角度看 ,茎所含相关元素对最多 ,而枝、皮最少。
In this study, the elemental content of the yellow huckleberry in the monsoon evergreen broad-leaved forests of Dinghushan was studied, and the contents of 6 elements in 9 different organs were analyzed. The results showed that: 1) The content of elements in different organs of the plant was N Leaf> branch> root> stem> leaf> branch> root> stem> K> leaf> branch> branch> root> stem, Ca: Skin> root> branch> stem. 2) The content of P in Zhaoli and Huangguo shell was higher than that in the other two species. The content of P in Zhaolin, Yinyinbaixian and Danggui fern was higher. The content of K similar. 3) Nutrient content showed a certain level of differences, the upper leaves of P content higher than the lower species, but the difference was not significant K content. The contents of N, P and K in the upper stems were significantly lower than those in the lower ones. There was no statistically significant difference in the individual nutrient contents at different levels among the populations of C. huanggui, however, the lower individuals had higher stems and lower stalks. 4) There are many significant pairs of elements among different elements in the community, where N has the highest correlation with other elements, followed by Mg, P, and again K, while Na is not related to any other element and Ca is rare. From the organ point of view, the stem contains the most relevant elements, and branches, skin at least.
