摘要： 为了研究络合铁的形态和质量浓度对藻类增殖的影响，以水华鱼腥藻（Anabaena aquae）和四尾栅藻（Scenedesmus quadricanda）分别作为蓝藻、绿藻代表藻种，选取EDTA铁、腐殖酸铁、草酸铁、柠檬酸铁铵4种不同络合态铁设计藻类增长潜力实验（Algal Growth Potential，AGP）. 结果表明：铁形态对四尾栅藻的生长影响显著（P≤0.05），铁质量浓度对其影响非常显著（P≤0.01），且铁质量浓度大于铁形态的影响. 水华鱼腥藻对于铁的形态和质量浓度的适应性较强，但过高的铁质量浓度仍会对水华鱼腥藻的生长有抑制作用. 铁形态对水华鱼腥藻的生长没有显著影响，而铁质量浓度对其影响非常显著（P≤0.01）. 对于水华鱼腥藻增殖的影响，铁质量浓度要远远强于铁形态.

Abstract: To study the effect of complex iron form and concentration on the growth of algae, EDTA-Fe, ferric humate, iron oxalate and ferric citrate were chosen to conduct a series of AGP experiments, which took Scenedesmus quadricanda and Anabaenaaquae as representative species of cyanobacteria and chlorophyta. The results show that both iron form and concentration have significant effect on the growth of Scenedesmus quadricanda. Besides, the latter (P≤0.01) is more effective than the former (P≤0.05). Anabaena flosaquae has a strong adaptability to the iron form and concentration. But high iron concentration still has an inhibitory effect on algal growth. The iron concentration has a very significant effect on the growth of Anabaena flosaquae (P≤0.01), while the iron form has no significant effect on them. Consequently, the iron concentration has a greater impact than the iron form on the growth of Anabaena flosaquae.

Key words: Scenedesmus quadricanda, Anabaena aquae, complex iron, growth
