- 摘要:
- 以荷花、睡莲、水葱、千屈菜、凤眼莲5种具有观赏价值的水生植物为试验对象，研究了5 种水生植物的生长状况、对水体中总磷、总氮和氨氮的吸附能力和对富营养化水体的净化效果。结果表明：5种水生植物对总氮的吸收能力，前5 d内荷花的除氮最高，清除率达到了27.0%，而睡莲最低，只有6.7%；第10天时，5种植物对总氮的清除率有了明显差异，凤眼莲的增幅最大，清除率达到了49.9%，其次是睡莲，达到了36.7%，其它3种植物对总氮清除变化不明显；第25天时，5种植物的清除总氮速度基本稳定，这5种水生植物对总氮清除能力为：凤眼莲>睡莲>水葱>荷花>千屈菜；5种水生植物对总磷的清除能力上，都是随时间的延长清除率越高。凤眼莲、睡莲、水葱、千屈菜、荷花30 d内，水体的总磷去除率达97.9%、93.8%、89.9%、81.6%和79.6%。因此清除总磷能力由高到低依次为：千屈菜>水葱>凤眼莲>睡莲>荷花。
- 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.
