摘　　要：【目的】采用红外辐射处理极大螺旋藻以提高其产量。【方法】分别使用远红外（2～25μm）、近红外（940nm和850nm）处理极大螺旋藻,测定其最终干重和生长速率,研究不同波长红外线对极大螺旋藻生长的影响。【结果】极大螺旋藻经远红外（2～25μm）辐射处理后的最大干重为对照组的3倍,经940nm红外处理后的最大干重为对照组的2.3倍,经850nm红外辐射处理后的最终干重与对照组相差不大。【结论】远红外（2～25μm）和940nm波长的近红外对极大螺旋藻的生长都有促进作用,而850nm红外对极大螺旋藻的生长无促进作用。【Objective】The production of Spirulina maxima was increased by infrared radiation treatment.【Methods】Far-infrared light（2～25μm）,940 nm and 850 nm infrared light were used to treat Spirulina maxima.The last dry weight and growth rate were measured.The effect of different infrared wavelengths on growth of Spirulina maxima was studied.【Results】The last dry weight and growth rate of Spirulina maxima,which had been processed by the far-infrared light（2～25μm）,was three times more than the control group.Spirulina maxima had been processed by 940 nm infrared light was twice more than the control group,while Spirulina maximahad been processed by 850 nm infrared light was the same as the control group.【Conclusion】Far-infrared light（2～25μm）and 940 nm infrared light can promot the growth of Spirulina maxima,but 850 nm infrared light can not.
