摘要
采用固定标准地的标准木法,对樟子松人工林林木营养元素含量与分布进行了研究。结果表明:樟子松林木体内养分元素中大量元素N和Ca的平均含量较高,然后依次是K、P、Mg;微量元素中以Fe含量居最高,然后依次是Mn、Zn、Cu。樟子松林木体内营养元素含量主要集中在叶、枝和根中,其中以针叶和<2 mm的细根等部位较高。
An experiment was conducted to study the content and distribution of nutrient elements in trees of Pinus sylvestris vat. mongolica by sample tree harvest method in a long-term sample plot. Mean content of macronutrients exhibited N 〉 Ca 〉 K 〉 P 〉 Mg and that of micronutrients showed Fe 〉 Mn 〉 Zn 〉 Cu. The allocation of nutrient elements was observed mainly in needles, branches and roots, especially in needles or roots with diameter less than 2mm.
