Both of Eichharnia crassipes and Hosta ventricosa can grow normally in a single nitrogenand phosphorus stress condition, The higher the concentration of nitrogen and phosphorus in waterthe higher the chlorophyll content and dry matter content in plants, it means the growth of plants isgood, This proves that Eichhamia crassipes and Hosta ventricosa has a very strong ability to adaptin a single nitrogen and phosphorus pollution water, they can be used for repairing a singlenitrogen and phosphorus pollution water.

在单氮和单磷胁迫条件下植物都能够正常生长，并且水体中氮、磷浓度越高凤眼莲和紫萼玉簪体内的叶绿素含量及干物质含量就越高，说明两种植物的生长状况就越好，这一点证明两种植物对氮、磷污染的适应能力都很强，可以用于修复单氮和单磷污染水体。
