| 摘 要： | 本实验初步研究了海链藻对氮磷的需求，研究结果表明：以等摩尔氮的NH4Cl、NaNO，和NFLNO3作为氮源时，选择NH4NO3为氮源可以获得较快的生长率并维持较长时间的指数生长期；氮源浓度的最适范围在0．54-1．08mmol／L之间。而2．16mmol／L以上的高浓度NH4NO3则对海链藻的生长有一定的抑制作用；在不同磷浓度(0．015-0．12mmol／L)的条件下，海链藻保持大致相同的生长速率。

| Abstract: | In the present paper, the nitrogen and phosphorus requirement of Thalassiosira sp. wereinvestigatedpnmanly. Theresult ofexperiments showed Thalassiosira sp. grew more rapidly and maintained longer at logarithmic period when used NH4NO3 as N resource than that used NH4Cl and NaNO3 as N resource of thesalne quantgy; and the apt range of N resource was from 0. 54mmol/L to 1. 08mmol/L, but high concentration (more than 2. 16mmol/L) of NH4NO3 inhibited the growth of Thalassiosira Sp. to some degree. In case of different concentration of phosphorus (from 0.015mmol/L to 0. 12mmol/L), Thalassiosira sp. could obtain well - nigh same growth rates. |
