大连沿海13种速生海藻无机营养元素的分析

An Analysis of Inorganic Natrition Elements from Thirteen Kinds of Quick-growth Seaweeds along Dalian Coastline

分析了采自大连沿海的 13种速生海藻的无机营养元素的含量 ,并针对不同生长季节、不同海域对分属于不同门类的 4种海藻富集无机元素的能力进行比较。结果表明 :13种海藻中均含有钾、钙、磷等常量元素和铁、锰、铜、锌等微量元素。其中 ,褐藻门的钾、钙含量最高 ,绿藻门的磷含量最高 ;微量元素中 ,绿藻门的铁、铜含量最高 ,而红藻门的锰、锌含量最高。海藻富集无机元素的能力与海藻种类。

In this paper,inorganic nutrition elements are examined from thirteen kinds of quick-growth seaweeds~ along Dalian Coastline.Comp^arative studies are conducted to inorganic element-accumulating ability~ of 4 kinds of seaweeds~ which belong to Chlorophyta,rhodophta or phaeophyta in varying gr^owing-seasons and sea areas.The results~ indicate that all of seaweeds contain such normal elements as k,Ca P and such trace elements as Fe,Mn,Cu,Zn.of these seaweeds the element content of K and Ca in phaeophta are highest,chloraphyta'spis highes^t.As for trace~ elements,chlorophyta contains the highest of Fe and Cu,rho~~dophyta contains that of Mn and Zn.The inorganic~ element-accumulating ability of seaweeds varies with spesies,growing-seasons and sea areas.
