螺旋藻是一种经济价值很高的微藻。针对螺旋藻的高光效性，在不同波长LED灯照射下，研究光照对螺旋藻生长速率的影响。结果表明，在螺旋藻的养殖中，经过红光（650-675 nm）、绿光（522-532 nm）和蓝光（465-475 nm）处理后，获得最大螺旋藻的干物质含量分别为1．232 g/L、1．195 g/L、0．742 g/L；红光处理过的螺旋藻生长速度最快，所得的干物质含量比对照样增加了66．04％。%Spirulina is a kind of microalgae with high economic value.Based on the characteristics of high lighting effects,the influence of light with different wavelengths on the growth rate of spirulina was studied in this paper.The re-sults show that the most dry matter content of spirulina is respectively 1.232 g/L,1.195 g/L and 0.742 g/L after illu-minating by the red LED light source(wavelength of 650-675 nm),the green LED light source(wavelength of 522-532 nm)and the blue LED light source(wavelength of 465-475 nm)in culturing of Spirulina.Moreover,the growth rate of spirulina is the fastest in red LED light source,and the dry matter content of spirulina increased by 66.04% as com-pared with those of ordinary spirulina.
