| 中文摘要: |
| 研究了大型海藻孔石莼和角叉菜去除硝酸盐和磷酸盐的效果，以及硝酸盐浓度对大型藻类生长及生化组成的影响。结果表明，高硝酸盐浓度（３０ｍｇ／Ｌ，标记为Ｎ３０）下海藻生长速率低于低硝酸盐浓度（１０ｍｇ／Ｌ，标记为Ｎ１０）。２种硝酸盐浓度下，孔石莼的生长速率均显著高于角叉菜。Ｎ３０条件下２种海藻对硝酸盐的平均去除率均显著高于Ｎ１０条件下的（Ｐ＜０．０５）；Ｎ１０条件下２种海藻对硝酸盐的平均去除率无显著差异（Ｐ＞０．０５），
Ｎ３０条件下角叉菜去除率显著高于孔石莼（Ｐ＜０．０５）。２种藻类对磷酸盐的平均去除率无显著差异（Ｐ＞０．０５）。一级反应动力学方程可以较好地描述孔石莼和角叉菜去除水中硝酸盐和磷酸盐的过程，并可大致分为３个阶段。经１０ｄ培养后添加氮、磷培养的２种海藻体内水分含量变化不大，粗蛋白和粗脂肪含量则有所增加，且Ｎ３０培养海藻的粗蛋白和粗脂肪含量均略高于低浓度硝酸盐培养海藻。 |
| 英文摘要: |
| The removal of nitrate and phosphorus，growth，and biochemical compositions of macroalgae，Ulva pertusa and Chondrus ocellatus Holmes cultured at adding different concentrations of nutrients were investigated. Growth of U. pertusa at lower concentration of nitrate(10 mg/L) was faster than that at higher concentration of nitrate(30 mg/L).The average of nitrate removal efficiency at higher concentration was significantly greater than that at lower nitrate concentration(P<0.05).The difference of mean efficiency of nitrate removal between U. pertusa and C. ocellatus were not observed at lower concentration of nitrate. The process of nitrate removal by two macroalgae could be described by the first-order dynamics equation. Both of the crude protein and lipid of two macroalgae increase at adding nitrogen and phosphorus after ten days' culture; and which at higher concentration of nitrate were greater than that at lower concentration as well.
