摘要

[目的]研究盐地碱蓬（Suaeda salsa）由陆地生境转移到浮床盐水生环境后的生长情况及其对海水养殖池塘水体原位修复的效果，为利用盐生植物原位修复海水养殖池塘提供方法。[方法]测定修复期间盐水浮床和陆地两种生境下盐地碱蓬的生长及生理生化指标，并监测海水养殖池塘水体水质。[结果]试验期内浮床生境中盐地碱蓬适应良好，生物量显著增加，其中浮床生境盐地碱蓬根系活力、叶片含氮量分别显著高于同期陆地生境中的盐地碱蓬。水质检测表明，修复后浮床区水体中总氮、总磷、氨氮和化学需氧量分别为3.34，0.20，0.47，0.35 mg/L，均明显低于对照区，去除效果良好。[结论]盐地碱蓬从陆地生境转移到浮床盐水生境后可以适应水生环境，并通过根系吸收部分去除水中的氮、磷等污染元素。盐地碱蓬原位修复海水养殖池塘水体具有较好的潜力。

Abstract

[Objective] To study the growth of Suaeda salsa transferred from a terrestrial habitat to a floating-bed saline habitat and its effect on the in-situ water remediation of aquaculture ponds

in order to provide methods for aquaculture water body remediation by floating bed.[Methods] The growth

physiological and biochemical indexes of S. salsa under saltwater floating bed and land habitats during the restoration period were measured. Water quality of the aquaculture ponds was monitored as well.[Results] The S. salsa was well-adapted the floating bed habitat during the experiment period. Biomass was increased significantly

and the root activity and leaf nitrogen content of S. salsa in the floating bed habitat were higher than that in the land habitat. The total nitrogen

total phosphorus

ammonia and chemical oxygen demand was 3.34

0.20

0.47

and 0.35 mg/L

respectively

which was lower than the control treatment.[Conclusion] S. salsa can adapt to the aquatic environment after transferred from terrestrial habitat to floating-bed saline habitat

and it can remove nitrogen

phosphorus and other elements in the water through the root absorption. S. salsa has a good potential for in-situ remediation in aquaculture pond water.
