人工基质无土栽培萱草对富营养化水的净化研究

A Study on Purification of the Eutrophic Water with Hemerocallis fulva Linn. Cultured on Artificial Substratum

利用小型人工基质无土栽培萱草,研究其在轻度和重度富营养水中的生长及净化能力。结果表明,萱草在两种程度的富营养水中生长良好,并能有效地去除TN、TP,尤其在冬季仍能维持一定的净化能力。因此萱草是杭州地区较为适宜的净水植物。

The growth and the purification ability of Hemerocallis fulva Linn. in heavy and light eutrophic water were studied by means of soilless cultivation technique on artificial substratum. Results showed that Hemerocallis fulva Linn. not only could develop well in the two different degree eutrophic water, but also could remove TN and TP effectively. And it also had some effect in winter that was the suitable local plant to be used through the year.
