| 摘 要： | 将鸢尾和菖蒲种植在椰丝基质上并放入富营养化的水塘中,实验在自然条件下进行.分别测定鸢尾和菖蒲的根、茎、叶不同器官中氮、磷的含量和植物种植期间生物量的变化状况.结果表明,植物根、茎、叶对氮、磷的积累量有显著差异,叶是两种植物积累氮、磷的主要器官;叶中的氮、磷积累量在实验后期,即11月中下旬时达到峰值;菖蒲各器官氮、磷含量均高于鸢尾,但是单株鸢尾对氮、磷的积累量比菖蒲大.

| Abstract: | Hydrophytes (Iris tectorum and Acorus calamus) were planted on the thread of coco in an open pool of eutrophic water. TN and TP in roots, shoots and leaves and biomass samples were measured. A wide range of TN and TP concentration were found in different organs; the leaf accumulated large amounts of N and P which peaked in late October. Acorus calamus was more efficient for accumulating N and P, while Iris tectorum had more N and P per plant as a result of its much higher biomass. |
