摘要
在实验室模拟条件下,研究了温度、光照、盐度和pH值对直链藻生长的影响。结果表明:直链藻生长的适宜温度为10～30℃,最适温度为25℃;适宜光照为500～9000lx,最适光照为3000～7000lx;适宜盐度5～85,最适盐度为20;适宜pH值为4～10,最适pH值为8.5。
The effects of temperature,illumination intensity,salinity and pH on the growth and reproduction of Melosira sp. were analyzed under the experimental conditions. The results indicated that the adaptive water temperature ranged from 5 ℃ to 30 ℃ with the optimal temperature at 25 ℃; the adaptive illumination intensity was 500—9 000 lx with optimal value at 3 000—7 000 lx; the range of adaptive salinity was 5—85 with the optimal salinity at 20; the range of adaptive pH was 4—10 with the optimal pH at 8.5.
