| 摘 要： | 本研究比较了污染水体中浮床水培蕹菜与陆生同种蕹菜之间生长特性以及N、P含量的差异。结果表明，水培蕹菜单株鲜重约为792．5g／株，为陆生蕹菜的3．53倍；单株N、P总量分别比陆生高469．6％、566．7％。水培蕹菜与其他水培植物相比具有较强的N、P吸收力，是一种可用于富营养化水体水质净化的优良植物。

| Abstract: | Experiments were carried out to compare the growth features and N, P contents of Ipomoea aquatica Forsskal planted at the floating -bed（ polluted water）and on the soil. Results show that on the average fresh -weight of the plants at the floating bed on the water surface is of 792. 5/per plant, which is 3.53 times of those planted on soil. The N and P contents from the water planted one are higher than the soil planted ones by 469.6% and 566. 7%, respectively. Compared with other floating - bed plants. Ipomoea aquatica had good effects on absorbing N and P. Results suggest that Ipomoea aquatica is a qualified plant for purifying of eutrophicated water bodies. |
