通过LED光照实验，探究不同光质和光周期对小麦草生长速率的影响。采用大功率红、蓝LED灯，红光峰值波长为655 nm，蓝光峰值波长为438 nm。实验采用控制变量法，以光质和光周期为变量，其余生长环境保持一致。结果表明：红光照射下生长速率要明显优于蓝光，甚至超过室内日光。在红蓝复合光中，红光光强高于蓝光时，更利于小麦草生长；连续24 h的光照与间隔12 h的光照相比，略有生长优势。

The purpose is to explore the impact on wheat grass growth rate in different light quality and light cycle.U-sing high-power red and blue LEDs through the LED illumination experiment.The red peak wavelength is 655 nm,the blue,it peak wavelength is 438 nm.The experiment used control variable method,regarded light quality and light cycle as a variable,the rest of the growing environment were the same.The experiment results show that the red is significantly better than blue,even more than the indoor natural light.In the complex of red and blue,when red light intensity is higher than blue,it is more conducive to the growth of wheat grass:For 24 hours of light compared with the interval of 12 hours of light,there is a slight growing advantage.
