| 摘 要： | 目的]观察重金属离子Cr^3＋、Zn^2＋对藻类生长的影响，为渔业生产及环境保护提供理论依据。方法]在试验条件下，分别用不同浓度（C=0．01～100．00mg/L）的Cr^3＋、Zn^2＋处理绿藻门亚心型大扁藻（Rlztymonas sp.）。结果]0．10mg／L Zn^2＋溶液促进亚心型大扁藻生长的效果最好，Cr^3＋、Zn^2＋浓度过高或过低都不利于亚心型大扁藻的生长。结论]充分利用各种海洋及淡水藻类对污水进行净化是一条高效、节能的理想途径。

| Abstract: | Objective]The purpose was to observe the effects of heavy metal ions Cr3+ and Zn2+ on the growth of algae so as to supply theoretical basis for fishery production and environmental protection.Method]Under experimental condition,the Plztymonas sp.of chlorophyta was treated with Cr3+ and Zn2+ at different concn.(0.01-100.00 mg/L) resp.Result]The promoting effect of Zn2+ solution at 0.10 mg/L on the growth of Plztymonas sp.was best,both higher and lower concn.of Cr3+ and Zn2+ went against its growth.Conclu... |
