Remediation effects of Suaeda salsa floating bed on nitrogen and phosphorus in marine-culture tail water
摘要
Abstract
The main cause of eutrophication of seawater is excessive nitrogen and phosphorus in the tail water of maricul-ture.In order to explore remediation effects of Suaeda salsa floating bed on nitrogen and phosphorus in marine-culture tail water.Two groups of contrast experiments were designed: adding S.salsa floating bed and without floating bed,by comparing the changes of plant height,biomass,moisture content,root length and content of nitrogen and phosphorus in different parts of plant at the beginning and the end of experiments.Removal effects of total nitrogen (TN) and total phosphorus (TP) in water were also measured to verify the removal ability of S.salsa to nitrogen and phosphorus in ma-rine-culture tail water as well as to explore the effects of S.salsa on accumulation of nitrogen and phosphorus and their growth characteristics.The results showed that S.salsa could adapt well to the floating bed culture environment of saline-culture tail water and there was a significant increase in plant height,biomass,water content and root length.The accu- mulations of N and P were mainly in leaves and roots of S.salsa.N and P accumulation effects of S.salsa accounted for 16.10% and 78.15%on TN and TP removal in water.This results can provide a reference for further study of the role of S.salsa in purifying of tail water in seawater pond and the use of floating bed to repair the tail water of mariculture.关键词
