本文研究了闽南绿竹（Ｄｅｎｄｒｏｃａｌａｍｏｐｓｉｓｏｌｄｈａｍｉ）林硼元素的含量特征，以及１９９６年７月至１９９７年６月绿竹叶和分解细根硼元素含量的月变化。其结果表明：１绿竹林各组分的硼元素含量大小不同，杆的含量最高，其次是叶，枝、根茎、细根含量则很低。２一年中绿竹叶的硼元素含量有一定的季节变化，春季硼元素的含量逐渐升高；在生长盛期的夏季，硼元素的含量波动较大，９月含量最高；从秋季到冬季硼元素的含量逐渐下降。３绿竹细根分解的前４个月，硼元素含量呈现上升的趋势，而后８个月硼元素的含量处于释放和累积的相间波动之中。
In this paper, the content of boron in Dendrocalamopsisoldhami forest in Minnan was studied, as well as the monthly variation of boron content in the leaves and decomposed fine roots from July 1996 to June 1997. The results showed that: 1. The contents of boron in different components of bamboo forest were different, the contents of stems were the highest, followed by the leaves, branches and rhizomes, while the contents of fine roots were very low. 2In one year, the content of boron in green bamboo leaves had a certain seasonal change, and the content of boron in spring increased gradually. During the peak growing season, the content of boron had a great fluctuation and the content was the highest in September. From autumn to Winter boron element gradually decreased. In the first four months of fine root decomposition, the content of boron increased gradually, and the content of boron in the last eight months was in the phase of release and accumulation.
