摘　　要：通过一次培养试验,分别研究了培养液中营养盐N、P、Si、Fe浓度变化对球等鞭金藻(Isochrysisgalbana)生长速率的影响。实验结果表明,生长速率与单一营养盐浓度符合Monod方程,而且将Monod方程扩展得到了可以表示多种营养盐对球等鞭金藻生长的复合限制模式。The effects of nutrients on the growth rates of Isochrysis galbana were studied by batch culture.The results indicate that the effects of nutrient limitation on the growth rates oflsochrysis galbana can be described using the Monod equation,The multi-limitation model arrived by expanding the Monod equation could express the degrees of the different nutrient limitations.
