利用LED精量调制光源, 设置红光、蓝光、红蓝1∶1、红蓝7∶1共4个不同光质配比的LED植物补光灯实验组, 以室内自然光(CK)为空白对照组, 对芦荟盆栽进行补光处理, 基于SPSS软件对实验数据进行LSD多重方差分析, 研究不同光质配比对芦荟生长的影响。实验结果表明: 红光能促进芦荟叶片的伸长, 蓝光有利于促进芦荟叶片厚度的增加, 红蓝7∶1光处理下的芦荟生长效果最好, 是本次实验中的最佳光质配比。

Red, blue, R∶B=1∶1, R∶B=7∶1 total 4 different light quality of LED plant lights were set as supplement light sources for potted aloe, and the influence of different light quality on the growth of aloe was researched using the indoor natural light as the blank control group. SPSS software was used for LSD multiple analysis of variance of the data. The results show that the red light source can promote aloe leaf elongation, the blue light source can promote the aloe leaf thickening, and the composite optical quality R∶B=7∶1 is the optimum light quality ratio with the best aloe growth effect.
