基于作用光谱的西红花LED补光灯具光谱研究

西红花是一种经济价值很高的药材。光谱是植物生长的重要影响因素,因此探索最适合西红花物质积累的补光光谱很有意义,但目前还缺乏对西红花室外补光参数的研究。本文利用西红花叶片的作用光谱,半定量分析补光灯具对西红花物质积累的增益。进一步评估了不同光谱的LED补光灯具对西红花干物质的增益效用。理论计算结果表明,低色温的宽光谱白光或红光与少量蓝光的组合更适合作为西红花LED补光灯具的光谱。

Study on the Spectra of LED Supplemental Luminaires for Saffron Based on its Action Spectrum

Saffron is a kind of medicine with high economic value.The spectrum plays an important role in plant growth,so it is very meaningful to explore the most suitable spectrum for saffron biomass accumulation.However,there is still a lack of research on outdoor supplemental lighting parameters for saffron.This paper used the action spectrum of saffron leaves to semi-quantitatively analyze the effect of supplemental luminaires on the saffron biomass accumulation.We further evaluated the effect of LED supplemental luminaires with different spectra on the dry matter accumulation of saffron.According to the theoretical calculation results,it is suggested that the spectrum of LED supplemental luminaires for saffron should be broad spectrum white light with low color temperature or the combination of red light with a little blue light.
