| 摘 要： | 文章研究了橡胶＋砂仁胶园间种模式凋落物的年凋落总量和节律、凋落物组成、分解速率、营养元素及养分释放。结果表明：橡胶林下间种砂仁的胶园凋落物具有较多的热带季雨林的特征，总凋落量为７．６５ｔ／ｈｍ２·ａ，与海南岛山地雨林相近；凋落物组分中明显较高的叶含量形成了橡胶＋砂仁模式自己独特的凋落物组分比值；占凋落物总量３９．７％的砂仁枯落物，在胶砂复合生态系统的养分归还上占有十分重要的地位。

| Abstract: | Annual litter fall and distribution, litter component and decomposition rate, nutrient content and release are mentioned in this paper. The results indicate that litter character of Hevea brasiliensis + Amomum villosum plantation was quite similar to that of tropical mansoon rain forest. Annual litter fall amount was 7.65 t/hm 2, similar to the amount of tropical monsoon rain forest. But this plantation had more leaf litter than others. Amount to 39.7% of the total, Amomum villosum litter fall was very important to nutrient return in the integrated ecosystem. |
