摘要
采用浮床无土栽培技术 ,在池塘水面种植景观植物——陆生植物美人蕉 (Cana generalis Bailey)以控制池塘富营养化水质。结果显示 ,在富营养化池塘中 ,景观植物的覆盖率与水体中氮、磷等的去除率呈显著正相关 ,即提高景观植物的覆盖率可以提高水质的净化能力 ,使电导率和浮游植物叶绿素 - a也明显下降 ,表明了富营养化池塘的水质得到了明显改善。在富营养化池塘中 ,景观植物的较佳覆盖率最好是 2 0 %。
The control of eutrophic water in ponds were tested by culturing landscape plant canna ( Cana generalis Bailey) on soilless floating beds. The results indicated that the coverage of the landscape plant correlated positively with the removal rates of nitrogen and phosphorus in pond water, and increase of the coverage rate of the landscape plant could increase removal rate, conductivity and chlorophyll a also significantly decreased. Results showed that water quality of eutrophic ponds was improved significantly. In eutrophic ponds , the 20% coverage of the landscape plant would be the best.
