Abstract:
Taking five ornamental value aquatic plants of Nelumbo nuccifera,Nymphaea Linn spp, Scirpus tabernaemontani Gmel，Lythrum salicaria L，Eichhounia crassipesas materials，the growth status and the adsorption ability of 5 kinds of aquatic plants to water in the total phosphorus，total nitrogen and ammonia nitrogen and eutrophication purification effect were studied.The results showed that the five kinds of aquatic plants to absorb the ability of total nitrogen，before 5 days of Nelumbo nuccifera in the highest nitrogen，clearance achieved 27.0%，and the lowest Nymphaea Linn spp，only 6.7%；10 days，five species of plants to total nitrogen had significant difference of clearance，the largest rise Eichhorina crassipes，up to 49.9% of the clearance followed by Nymphaea Linn spp，to 36.7%，the other three plants to total nitrogen removal change was not obvious，25 days of five plants remove total nitrogen speed basic stability，the five kinds of aquatic plants on the total nitrogen removal ability for：Eichhorina crassipes >Nymphaea Linn spp > Scirpus tabernaemontani Gmel> Nelumbo nuccifera> Lythrum salicaria L；5 kinds of aquatic plants on the total phosphorus removal ability，with the extension of time，the higher the clearance.Eichhorina crassipes，Nymphaea Linn spp，Scirpus tabernaemontani Gmel，Lythrum salicaria L,Nelumbo nuccifera，within 30 days of the water to phosphorus removal rate of 97.9%，93.8%，89.9%，81.6% and 79.6%.So remove phosphorus ability from high to low in turn for：Lythrum salicaria L>Scirpus tabernaemontani Gmel > Eichhorina crassipes> Nelumbo nuccifera> Nelumbo nuccifera.
