摘要:

为研究浮床栽培黄花水龙(0%、5%种植面积)对红罗非鱼养殖池塘污染物的影响,测定CODMn、Chl.a、TN、NH3-N、NO2--N、NO3--N、TP、PO43--P等水质指标。结果表明,与对照组相比,黄花水龙能显著降低红罗非鱼养殖池塘水体中Chl.a、NH3-N、NO2--N指标,也能显著降低CODMn、TP、TN和NO3--N含量,其中对NO3--N和NO2--N平均去除率达50%以上,而对磷的去除效果不佳。

Abstract:

To study the influence of the floating bed culture of Jussiaea stipulacea (0, 5% planting area) on the pollutants in the culture pond of red tilapia (Oreochromis mossambicus× O. niloticus), the water quality indexes, such as CODMn, Chl.a, TN, NH3-N, NO2 --N, NO3--N, TP and PO43--P, were determined. The results showed that compared with the control group, J. stipulacea could significantly reduce the contents of Chla, NH3-N, NO2 --N, as well as the contents of CODMn, TP, TN and NO3 --N in the culture ponds of red tilapia. The average removal rate of NO3--N and NO2--N was more than 50%, but the removal effect on phosphorus was unsatisfactory.
