摘 要 ：油松(Pinus tabulaeformis carr.)是华北地区山地造林的主要树种之一,不同立地条件下和不同树种组成的油松人工林生长表现各异。本文试图从营养角度探讨这些人工林的差异。为此,对油松人工林内各树种[包括油松、元宝枫(Acer truncutum Bge)、侧柏(Platycladus orientalis(L.) Franco)]叶的N、P、K、Ca、Mg、Cu、Fe、Mn和Zn的元素含量进行了连续三年(1983—1985年)的研究。试验结果表明,不同树种不同立地条件下的元素含量不同。元宝枫的元素含量极为丰富,在其适生立地条件下尤其如此,因而元宝枫是营造油松混交林的良好伴生树种。不同年份和年内不同季节元素含量也有变化。这些数据可为林地施肥和森林抚育提供基础资料。

Abstract:The element content of N, P, K, Ca, Mg, Cu, Fe, Mn and Zn, in the leaves of every each tree species (including Pinus tabulaeformis, Platycladus orientalis and Acer truncaturn) in the plantations was studies lasted three years (1983—1985) in this paper.The result shows that the content of each element in the leaves of different trees growing under different site conditions is quite different. The content of each element in the leaves of the maple (Acer truncaturn) is very rich and it is much richer especially under suitable site. Therefore, the maple is a good associated tree species which is suitable for growing in the mixed stand together with the pine. The annual and seasonal variations of the content of each element provide basic materials for forest fertilizing and tending.
