摘要
[目的]为梭鱼草的水体景观应用提供理论依据。[方法]以凤眼莲和梭鱼草为研究对象,采用3个污染程度水体种植2种植物,测定COD和NH3-N指标的变化,研究凤眼莲和梭鱼草对水体的净化效果。[结果]2种水生植物都能够降低水体COD含量,净化水体。[结论]在类似水体2的水体景观绿化中,梭鱼草的净化效果和观赏价值均高于凤眼莲,应优先选用。
[ Objective] The theory basis for the water landscape depending on the barracuda grass was put forward. [ Method] The water hyacinth and mullet weeds as experimental material were planted in 3 levels of polluted water-body and the index of COD and NH3-N was inspected so that the effect of water hyacinth and ban-acuda grasss on the purification of water-body could be analyzed. [ Results] Both of 2 species of hydrophytes can reduce the content of COD in water-body for the purification of water-bedy. [ Conclusion] The barracuda grasses had much better effect on the purification of water-body than water hyacinth in the second water landscape design.
