在设施水培条件下,以黄金四季奶油小白菜为试验材料,LED灯为人工光源,自然光为对照,研究不同光谱LED植物光灯的红蓝光波段组合对黄金四季奶油小白菜生长参数的影响,为植物工厂水培小白菜提供人工补光数据支撑.试验设定为蓝光(455nm)相对光谱固定不变,红光相对光谱分别为T1(7.53％)、T2(15.40％)、T3 (30.28％)条件下的生长速度及品质.结果 表明,红光相对光谱为30.28％时试验组小白菜的菜叶长度、株高、蛋白质以及叶绿素含量均显著高于其他处理,30.28％的红光相对光谱可作为水培小白菜的适宜光配合.

Under the condition of hydroponic culture, the golden four seasons butter cabbage was used as the experimental material, the LED light was the artificial light source, and the natural light was used as the control. The effect of the combination of the red and blue light bands of different spectral LED plant lights on the growth parameters of the golden season white cabbage was studied. Provide artificial light supplement data support for hydroponic cabbage in plant factories. The experimental setting was such that the relative spectrum of blue light (455 nm) was fixed, and the relative spectra...
