Abstract:

Greenhouse static state experiments were conducted to investigate 9 Species of Genus Iris′ on removal effect on nitrogen and phosphorus in eutrophic water. Results indicated that all of the three species grew well,and showed excellent nitrogen and phosphorus removal capacities. The Iris keampfer was best, the Iris pseudacorus was slightly inferior, the two difference was not obvious, the Iris sanguinea was worst. But Iris pseudacoru growth condition was obviously better than the other two. The Iris keampfer and the Iris pseudacorus may given the primordial consideration in the next government in eutrophic water.
