Abstract:
The typical submerged plants of Ningxia，Najas marina L.，Myriophyllum verticillatum L. and Potamogeton pectinatus L. were used as experimental materials.The effects of different water depths (60，40，20 cm) and shading conditions (30%，60%，100%) on the morphological characteristics and nitrogen removal of three submerged plants were studied by controlled laboratory experiments，in order to provide reference for the introduction and purification of submerged plants.The results showed that the abundance and survival rate of Najas marina L.，Myriophyllum verticillatum L. and Potamogeton pectinatus L. decreased with the increase of water depth，and the plant height，plant diameter and water depth were inversely proportional.In the shading treatment，the change trend of abundance，coverage and survival rate of Najas marina L. and Myriophyllum verticillatum L. were equal，which were 30%>100%>60%.In the two experiments，the nitrogen removal rates of Myriophyllum verticillatum L. were the highest，which were 99.50% and 60.67%，respectively，and the maximum purification capacity was 11.43 L，and the equilibrium was the highest，which was more stable than other plants.It is suggested that in the future biological purification project in the northern area，the preferred species for the construction group is Myriophyllum verticillatum L..
