| 摘 要： | 通过对橡胶与砂仁间作林和同龄纯胶林各层次各器官生物量及１０种营养元素含量的测定，对比研究了两种分乔木层生物量按径级分配，林分平均净生产量，营养元素的积累分布规律，林龄为３０ａ，间作龄为８ａ的胶砂间作林的总生物量为１３９．８５ｔ／ｈｍ＾２。其中乔木层占７２．７％，间作层占２２．６％，枯落物层占５．２％，与同龄纯胶林相比，乔木层提高了７．６％，枯落物层提高了３８．９％，两种林分乔木层地上部分生物量约占

| Abstract: | In a rubber plantation intercropped with A. longiligulare(RA) and a pure rubberplantation (PP) of 30-year-old, biomass and nutrient element of each component of tree, in-tercrops and litters were detected. Biomassallocation in terms of diameter class, net productionand nutrient accumulation of two plantation, have been studied comparatively. The resultsshowed that the total biomass of RA was 139. 85 t/hm2, among which the biomass of trees,intercrops and litters accounted for 72. 7 %, 22. 6 %, and 5. 2 % res... |
