摘　　要：以八宝景天作为试验材料,采用不同红蓝比的LED光源(红蓝比9∶1、红蓝比3∶1、红蓝比1∶1、红蓝比1∶3、红蓝比1∶9)和天然光光照处理的方法。研究不同光源红蓝比的光环境条件对八宝景天的生长影响,提出了适用于八宝景天生长的补光光谱,为喜光景观植物的景观照明设计提供参考。不同于经济性作物研究,本文分析的重点在植物的观赏价值,围绕植物的形态学分析,测量的生长指标包括:株高、茎粗、叶片厚度、叶片面积、叶片相对光谱反射率和叶绿素含量。研究认为红蓝光能有效促进八宝景天生长,提高观赏价值。解决了立体绿化设计在城市及建筑空间中光照不足的问题。Hylotelephium spectabile was used as experimental material.The effects of different light qualities on the growth characteristics of Hylotelephium spectabile were studied by using LED light sources with different the ratio of red and blue(red blue ratio 9:1,red blue ratio 3:1,red blue ratio 1:1,red blue ratio 1:3,red blue ratio 1:9)and natural light treatment methods.The supplementary light spectrum suitable for the growth of Hylotelephium spectabile is proposed.Provide reference for landscape lighting design of heliophilous landscape plants.Different from the study of economic crops,this paper focuses on the ornamental value of plants.The measured growth indicators include plant height,stem diameter,blade thickness,leaf area,leaf relative spectral reflectance and chlorophyll content.The research believed that red and blue light can effectively promote the growth of Hylotelephium spectabile and improve its ornamental value.Solved the problem of insufficient lighting in urban and architectural space of three-dimensional greening design.
