摘要

采用实验室模拟培养的方法，分别培养初始柠檬酸铁铵、EDTA-Fe、草酸铁、腐殖酸铁质量浓度为0.2 mg/L、0.4 mg/L、0.6 mg/L、0.8 mg/L、1.0 mg/L时的水华鱼腥藻.结果表明：在相同络合态铁质量浓度下，柠檬酸铁铵与腐殖酸铁较之草酸铁与EDTA-Fe，生物可利用性更强，藻类表现出更快的促进时效及更大平均增长速率，但促进效果因络合态铁的浓度不同而略有差异；柠檬酸铁铵最适生长铁质量浓度出现在0.2 mg/L；EDTA-Fe、草酸铁最适生长铁质量浓度出现在0.6 mg/L附近；腐殖酸铁的最适宜生长质量浓度出现在0.4 mg/L附近.

Abstract

Anabaena flos-aquae

were cultured separately in ferric ammonium citrate

EDTA-Fe

ferrioxalate and ferric humate in the initial concentration of 0.2 mg/L

0.4 mg/L

0.6 mg/L

0.8 mg/L and 1.0 mg/L by using the laboratory simulation training method. The results show that the bioavailability of ferric ammonium citrate and ferric humate is stronger than the EDTA-Fe

and ferrioxalate under the same complex iron concentration in water. And the algae shows a faster growth rate and greater average growth rate in ferric ammonium citrate and ferric humate

but the promoting effect is slightly different due to the difference of the concentration of the complex iron. The optimum growth of iron concentration of ferric ammonium citrate

is 0.2 mg/L

and the optimum growth of iron concentration of EDTA-Feand ferrioxalate appeares in the vicinity of 0.6 mg/L

while the optimum growth of iron concentration of ferric humate appeares in the vicinity of 0.4 mg/L.
