摘　　要：[目的]探索培养基N含量对螺旋藻生长的影响。[方法]通过抽滤分离培养基与螺旋藻,测量滤液稀释10倍后的OD值来观察N含量变化,测量滤渣干重来观察螺旋藻的生长情况,从而找到最佳N浓度。[结果]当硝酸钠浓度为0.8 g/L时,螺旋藻生成最快,此时所得细胞密度为1.18 g/L,产量为21.8 g/(m2·d)。[结论]为家庭或办公室内生产螺旋藻时氮素的添加量提供指导。[ Objective ] Effect of the nitrogen concentration on growth of Spirulina platensis was explored. [ Method ] After the suction filter, OD value were measured at 210 nm of the filtrate of 10 times diluted to determine the concentration of nitrogen in the medium. The weights of S. plat- ens/s were measured to determine the growth of S. platensis. [ Result ] The results showed that the optimal concentration of sodium nitrate was O. 8 g/L, and the cell density was 1.18 g/L, the output was 21.8 g/（m^2 · d）. [Conclusion] The study provided the guidance for the amount of adding nitrogen in the home or office for production of Spirulina platensis.
