In nitrogen and phosphorus mixed pollution water, in thewater that the concentration of nitrogen is 21mg/L and the concentration of phosphorus is155mg/L, Eichharnia crassipes and Hosta ventricosa can grow normally. In the water that theconcentration of nitrogen is 210mg/L and the concentration of phosphorus is 31mg/L, thephysiological indicators of Hosta ventricosa is good but the physiological indicators of Eichhomiacrassipes is worse than the other treatment and the root of Eichharnia crassipes was rot when itwas planted in the 7th day, and on the 11th day the plants wilt symptoms, it noted that thistreatment affected the growth of Eichharnia crassipes.

在氮磷复合污染的水体中，凤眼莲和紫萼玉簪在氮浓度21mg／L，磷浓度155mg／L水体中都能够正常生长，而在氮浓度210mg／L，磷浓度31mg／L水体中，紫萼玉簪生长正常，而凤眼莲的生理指标比在其它处理中要差，并且凤眼莲在种植的第7天出现根部腐烂，11天时植株枯萎的症状，说明氮浓度210mg／L，磷浓度31mg／L复合污染在一定程度上影响植物的正常生长。
