| 摘 要： | 以铜绿微囊藻为试验材料,应用正交试验法,在培养温度(25℃)及接种量相同的情况下,研究光限制胁迫协同pH与氮磷比对铜绿微囊藻生长的影响.影响铜绿微囊藻生长的因素顺序为:pH>光限制胁迫天数>氮磷比,pH为铜绿微囊藻生长的显著性影响因素(F=63.111 5),且在pH 10.5、氮磷比15∶1及光限制胁迫5 d的条件下正常光照培养4 d后藻细胞数量最大.

| Abstract: | The synergistic effects of pH value,ratio of N /P,and light limitation on the growth of Microcystis aeruginosa were investigated by orthogonal tests. Results of orthogonal test for the selective preference of the growth condition for M. aeruginosa showed that pH can significantly affect the growth of M. aeruginosa,and the optimal factor combination is pH 10. 5,stress of 5 days and 15 /1 for N /P. Under 25 ℃,the order of effect on the M. aeruginosa is pH > stress of light limitation > N /P,detected after cultured under normal light intensity for 4 days. |
