| 摘 要： | 本文研究了两种优化经营措施油茶林中营养元素的含量、净积累和循环,以综合措施的油茶林作一实例,分析了生态系统中营养元素的循环过程,并提出了氮、磷、钾元素的循环局部动态模型。结果表明:(1)油茶林各器官的营养元素的含量呈现出氮>钾>镁>钙>磷的趋势,最高的是果或叶,最低的是树干。(2)当油茶林采取优化经营管理后,器官养分随之增高。如综合措施一年生叶氮、磷、钾含量分别高于对照的32.5％、26.5％、8.6％;而一年生枝中氮、磷、钾含量分别高于对照的26.5％、33.9％、1.7％。这更进一步证实了优化措施之所以产果量高,就是因为积累了充分养分,保证了生长发育的需要这一点。

| Abstract: | In the paper the content, net accumulation and cycling of nutrient elements in two oil-tea plantations under the optimization management measures were studied. Taking the oil-tea plantation as on example, the cycle process of nutrient elements in the ecosystem was analysed and some dynamics models of N, P, K elements were put forward. The results are as follows: (1) concentrition of nutrient elements in organs of the oil-tea standing crops tends toward N>K>Mg>Ca>P, the highest concentration of nutrient elem... |
