翼茧形藻的培养条件

摘要

The effects of temperature, illumination intensity, salinity, pH and nutrients on the growth and reproduction of Amphiprora alata was studied under the experimental conditions. It came to the conclusion that the adaptive water temperature ranged from 10 ℃ to 38 ℃ with the optimal temperature at 30 ℃ ;the adaptive illumination intensity was 500 - 10 000 Lx with the optimal value at 5 000 - 10 000 lx; the range of adaptive salinity was 2-80, and the optimal salinity was 60; the range of adaptive pH was 4-9, and the optimal pH was 7. 5. The optimal prescription for culture solution was: natural sea water, 10 mg · L-1 NaNO3 -N, 2 mg · L-1 NaH2PO4-P, 0. 2 mg · L-1 FeC6H5O7-Fe and 40 mg · L-1 Na2Si03-Si.%在实验室条件下通过单因子和正交试验,研究了温度、光照、盐度、pH值和氮、磷、铁、硅等营养盐对翼茧形藻(Amphiprora alata)生长繁殖的影响.结果表明:翼茧形藻生长的适宜温度为10～38℃,最适温度为30℃；适宜光照为500～10000 1x,最适光照为5 000～10 000 1x;适宜盐度为2～80,最适盐度为60;适宜pH值为4～9,最适pH为7.5.经方差实验,在天然海水中添加10 mg·L-1 NaNO:N、2mg·L-1NaiH2PO4-P、0.2mg·L-1 FeC.H5O7-Fe、40 mg·L-1Na2SiO3-Si,培养效果最佳.
