摘要
在实验室培养条件下,研究了温度、光照、盐度、pH值和氮、磷、铁、硅等营养盐对微小小环藻(Cyclotella caspia)生长繁殖的影响。实验结果表明:微小小环藻生长的适宜温度为10～40℃,最适温度为30～35℃;适宜光照为500～10 000 lx,最适光照为2 000～8 000 lx;适宜盐度为2～85,最适盐度为25～50;适宜pH值为4～9,最适pH为8.0～8.5。筛选出微小小环藻培养液配方是每立方米海水加入(NH2)2CO-N 30g,NaH2PO4-P 1 g,FeC6H5O7-Fe 0.1 g,Na2SiO3-Si 25 g。
The paper studied effects of temperature, light, salinity, pH value and nutrients on the growth and reproduction of Cyclotella caspia under cultivated conditions. Results showed that the suitable water temperature was 10 - 40℃and the optimum water temperature was 30 - 35 ℃. The suitable and optimal light density were respectively 500 - 10 000 lx and 2 000 - 8 000 lx. The suitable salinity was 2 - 85 with the optimal salinity of 25 - 50. The suitable pH value was 4 - 9 with the optimal pH value of 8.0 - 8.5. The nutritional solution selected for Cyclotella caspia growth was 1 m3 sea water with（ NH2 ）2CO-N 30g, NaH2PO4- Plg, FeC6HsOT-Fe 0. lg, NazSiO3-Si 25g.
