臺灣六種水生植物於冬季之水質淨化效果比較之研究

本研究主要以六種水生植物，研究其淨化水質之功效，並依照水生植物的特性分為著根水生植物與浮水植物兩大類，希望能夠比較出何種水生植物對於水質淨化的效果較佳。實驗結果發現，著根植物中，蘆葦效果最佳；浮水植物中，大萍效果最好。整體而言，在冬季蘆葦對水質淨化效果最好。著根植物中，臺灣萍蓬草與蘆葦因適合因採集過程造成根系受損，所以淨化成效不佳，後期才開始出現良好淨化效果。浮水植物中，浮萍與大萍雖然中後期生長狀況不佳，植物體部分出現枯黃破損，但仍具有淨化效果；布袋蓮部分，前期繁殖迅速效果很好，後期營養濃度不足，造成淨化能力下降；臺灣水龍則因病蟲害，造成水龍生長不佳降低效果。本研究結果有助於未來設計淨化型水池之水生植物選擇。

In this study, six aquatic plants, to study the effect of water purification, and in accordance with the characteristics of aquatic plants is divided into two major categories of root aquatic plants and floating plants, want to be able to compare what aquatic plants for water purification effect is better. The experimental results showed that root plants, Nuphar shimadai, the best results; floating plants, Eichhornia crassipes best. Overall, in the winter in Nuphar shimadai on the water quality purification best; Ludwigia (x) taiwanensis and Lemna aequinoctialis, water treatment effect is less obvious. With the root of the plant, the Nuphar shimadai from the early have the effect, and to maintain to the last; Phragmites australis suitable for growing in open water space, so the poor growth. Floating plant, Lemna aequinoctialis growth is rapid but little effect; Pistia strafiotes L.-about one month after planting began to be effective; Eichhornia crassipes works well; Ludwigia (x) taiwanensis effect is not obvious in winter too cold causing poor growth of the water dragon. This study will help design of purification type pond aquatic plants choose.
