摘要
研究了闽南绿竹［Ｄｅｎｄｒｏｃａｌａｍｏｐｓｉｓｏｌｄｈａｍｉ（Ｍｕｎｒｏ．）Ｋｅｎｇｆ．］林细根的生物量、生产力及细根的分解动态．结果表明：闽南绿竹林的细根生物量为９７６１ｋｇ／ｈｍ２，１９９６年７月至１９９７年６月一年的细根生物量有一定的季节变化，在春季最大；１９９６年７月至１９９７年６月一年的细根生长量为３５３７ｋｇ／ｈｍ２，其中５月的活细根量为最大值；细根的周转率为０．４６次／年；细根的半分解期为２３０ｄ．
This paper deals with biomass, productivity and decomposition dynamics of fine roots in Dendrocalamopsis oldhami forest in South of Fujian province. The results were shown as follows: fine root biomass of Dendrocalamopsis oldhami forest was 9 761 kg/hm 2, annual productivity from the July 1996 year to the June 1997 year was 3 537 kg/hm 2, fine root turnover rate was 0.46 time per year. The decomposition of fine root speed progressively up and half decomposition periods were 230 days.
