摘要
研究几种水生植物改良鳖池水质的作用 .结果表明 ,凤眼莲、满江红、水浮莲对鳖池水体中的亚硝态氮、氨态氮、硝态氮有一定的去除效果 .其中以凤眼莲效果最好 ,其相对去除率分别达到了 57.5% ,74 .3%和 6 6 .5% .利用水生植物改良鳖池水质在生产上有一定的应用前景 .
The present paper reports the role of improvement played by different hydrophetes on the water quality of cultured Trionyx sinensis . The results showed that Eichhornia crassipes、 Azolla imbricata and Pistia stratietes can remove nitrite, ammonium and nitrate from water of cultured Trionyx sinensis to a certain extent. The experimental results also demonstrate that the removal effect of Eichhornia crassipes on nitrite, ammonium and nitrate is the best, and the relative removal rates are 57.5 %、 74.3 % and 66.5 % respectively. There are some application prospects that hydrophetes remove the water quality of cultured Trionyx sinensis in cultivation.
