摘　　要：LED作为人工光源,能很好地降低能耗、调节光谱和强度并对植物进行近距离照射。利用光学软件DIALux,通过优化照度和效能值2个参数,发现8种不同的三维模型LED灯珠排布方式中同心圆形排布为最优方案。在此基础上,装配LED灯珠同心圆形排布的照明光源,研究特定功率下6种不同颜色的LED灯珠同心圆形排布照明光源对小麦生长的影响。结果表明:不同颜色的LED光照对小麦生长的作用明显不同,红色和橙色光照射环境下小麦茎秆生长较为迅速,而蓝色光照有助于麦苗的根系生长。As an artificial light source, LED can reduce energy consumption very well, provide controllable light intensity and spectrum with close irradiation to plant. In this study, the optical software DIALux was used and the intensity of illumination and the efficiency value were optimized for eight different configuration scheme of 3 D models of lamps with beads, from which LED beads with concentric circles configuration was found the best scheme. Then, six different colors of illumination systems of LED beads with concentric circles configuration at given power were fabricated and used as light sources for the investigation of their influences on wheat stalks’ growth. Results showed that the different colors of LEDs had different influences on wheat stalks’ growth. In red and orange light environment, wheat stalks grew more quickly while blue light helps to wheat root growth.
