扰动条件对铜绿微囊藻生长及磷吸收的影响

摘要

This paper relates to a study of disturbance effect on growth and phosphorus absorption of. Theresultsindicatedthatslight disturbance(25,100 r/min)were conducive to the growth and phosphorus absorption of .However,strong disturbance(175 r/min)produced inhibitory effect on the growth of.The reason might be moderate disturbance is beneficial to the uniform distribution of nutrients in the environment and the diffusion of Microcystis and water disturbance affects the absorption of nutrients and photosynthesis of.%研究以铜绿微囊藻为研究对象,通过设置不同强度的水体扰动,研究了铜绿微囊藻生长状态与其对磷营养盐的吸收情况与水体扰动之间关系.结果表明,较小的水体扰动(25,100 r/min)有利于微囊藻的生长,并可提高藻类对磷的吸收效率曰较大的水体扰动(175 r/min)则对微囊藻的生长等情况产生了抑制效果,其生长状况明显较差.这可能是由于适度的扰动条件有利于环境中营养物质的均匀分布与藻类代谢产物的扩散导致,水体扰动对藻类的影响机制主要在于其影响了藻类对环境中营养盐的吸收与光合作用等.
