摘要
本试验在水温26.6℃～30.6℃下,分别对密度相同的苦草、聚草、轮叶黑藻、伊乐藻、茭草、水浮莲、水花生、浮萍对水体中COD、NH4-N、NO3-N、NO2-N、TP、TN六个指标的最大去除率进行了对比研究.结果表明:在养蟹池塘中种植一定密度的水生植物有利于水体生态环境的改善.
The paper studied the most demineralized rate of Vallisneria spiralis?Myriophyllum spicatum?Hydrilla verticillate?Elodea nuttallii?Zizania caduciflora?Pistia stratiotes?Alternanthera philoxeroides?Lemna paucicostata in same density to COD,NH4-N,NO3-N,NO2-N,TP,TN at WT 26.6℃~30.6℃.The result indicated that its helpful to improve water quality and entironment that plant hydrophyte with stated density in culturing crab pond.
