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=63.1115),且在pH 10.5、氮磷比15∶1及光限制胁迫5d的条件下正常光照培养4d后藻细胞数量最大.
以銅綠微囊藻為試驗材料,應用正交試驗法,在培養溫度(25℃)及接種量相同的情況下,研究光限製脅迫協同pH與氮燐比對銅綠微囊藻生長的影響.影響銅綠微囊藻生長的因素順序為: pH >光限製脅迫天數>氮燐比,pH為銅綠微囊藻生長的顯著性影響因素(F=63.1115),且在pH 10.5、氮燐比15∶1及光限製脅迫5d的條件下正常光照培養4d後藻細胞數量最大.

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.
