泰山侧柏古树叶片矿质元素分析
|
摘要
为探究泰山侧柏古树营养元素含量与古树年龄与健康的关系,以泰山罗汉崖林场和王母池景区内12株侧柏古树为研究对象,对其叶片中15种矿质元素进行测定分析。结果表明:衰弱古侧柏中除Ni和Co含量低,其他元素均高于健康古侧柏。衰弱树和健康树叶片中Ca含量存在极显著性差异,Pb含量比健康树高29.35%,这暗示罗汉崖地区古侧柏生长衰弱可能与其体内Ca、Pb 2种元素过高有关系。不同龄级古侧柏叶片元素含量,仅Na元素在一级和三级侧柏古树间存在显著性差异,即龄级高的古侧柏Na含量低于龄级低的古侧柏。罗汉崖林场和王母池景区同健康水平同龄级古侧柏叶片矿质元素含量相当。该研究找出可能与侧柏古树衰老和树龄密切相关的元素含量及变化,为泰山地区古侧柏营养诊断、衰老评价提供参考理论依据。
To explore the relationship between nutrient elements' content and the age and health of Platycladus orientalis in Mount Tai, we measured and analyzed 15 mineral elements' content of 12 ancient Platycladus orientalis trees in Luohanya forest farm and Wangmuchi area. The results showed that: except Ni and Co, contents of other elements in weak ancient trees were higher than those in health ancient trees; besides,contents of Ca showed significant differences between the leaves of weak ancient trees and health ancient trees,and Pb in weak ancient trees was 29.35% higher than that in health ancient trees, which indicated that the weak growth condition of ancient Platycladus orientalis in Luohanya might be related to the high levels of Ca and Pb; there was significant difference of Na between the first and the third levels ancient Platycladus orientalis trees, that was to say, the content of Na in high age trees was lower than that in low age trees; mineral elements' content of ancient trees with the same health levels and the same age class levels were equivalent in Luohanya and Wangmuchi areas. This study finds out the contents and changes of the mineral elements closely related to the health and age of ancient Platycladus orientalis trees, and provides a reference for their nutrition diagnosis and health evaluation in Mount Tai.
