摘要: 研究了闽南毛竹群落中几种常量元素的累积情况,结果表明,在整个毛竹群落现存量中N、P、Si、K、Ca和Mg总累积量分别为13.96、2.89、70.04、41.29、5.84和3.63g·m-2.在毛竹的各组分中,竹叶中的各种元素含量均最高,竹鞭中元素含量也较多.6种元素中,Si的浓度最高,平均为1.60%,K次之,平均为0.55%.Si在叶中含量最高,达15.60g·m-2,N和K在竹杆中含量最高,分别为6.58和20.679·m-2.林下植物根中Si含量也高达11.45g·m-2.竹叶中Si含量很高还表明了它是从叶中含Si量低的木本植物向合Si量高的禾草进化的过渡类型.

Abstract: Studies on the accumulation and distribution of nutrient elements in Phyllostachy spubescens community of South Fujian show that the total accumultaion amount of N,P,Si,K, Ca and Mg is respectively 13.96,2.89,70.04,41.29,5.84 and 3.63g·m-2. Indifferent parts of Phyllostachys pubescens, leaf has the highest amount of these elements,and whip is the second. Among these 6 elements, Si has the highest concentration,1.60% on average, and K is the second,0.55% on average. The content of Si is thehighest in leaves, being 15.60g·m-2, and that of N and K is the highest in stems, beingrespectively 6.58 and 20.67g·m-2. The roots also contain a higher content of Si, being 11.45g·m-2. The high content of Si in leaves indicate that bamboo is a transitional typefrom woody plant (which has a lower content of Si) to grass (which contains more Si).

Key words: Phyllostachys pubescens community, Nutrient element, Element content
