不同LED补光对5种垂直绿化植物光合特性及生长的影响

目的]为解决植物在寡照的室内环境生长不良的问题.方法]研究不同LED补光处理对5种垂直绿化植物光合特性及生长的影响,比较叶绿素含量、光合速率、存活率3项指标.结果]补光处理能提高这5种植物的叶绿素含量、光合速率、存活率.与普通日光灯相比,LED灯补光处理能明显提高花叶良姜、吊竹梅、金苞花、龙船花内的叶绿素含量以及光合速率;LED 3（红/蓝/黄=7∶1∶1）补光处理显著提高花叶良姜的叶绿素含量,LED 1（红/蓝=7∶2）补光处理显著提高金苞花存活率.结论]LED灯补光有助于这5种垂直绿化植物的生长,为LED灯用于室内垂直绿化的植物墙补光提供了数据参考.

Effects of Light-emitting Diodes （LED） Supplemental Lighting on Photosynthetic Response and Growth of Five Kinds of Green Plants

Objective] The research aimed to solve plants growth problem in poor-light indoor environment.Method] The effects of light-emitting diodes （LED） supplemental lighting on the photosynthetic response and growth of five kinds of green plants were studied.Three indexes,including chlorophyll content,photosymhetic rate and survival rate were compared in the research.Result] Supplemental lighting improved chlorophyll content,photosynthetic rate and survival rate of five kinds of green plants.Compared with ordinary fluorescent,LED supplemental lighting dramatically improved chlorophyll content and photosynthetic rate of Alpinia vittata,Tradescantia zebrina,Pachystachys lutea,Ixora chinensis and Rhoeo spathacea.LED 3 （red∶ blue∶ yellow =7∶ 1 ∶ 1） supplemental lighting greatly improved chlorophyll content of Alpinia vittata.LED 1（red∶ blue =7∶2） supplemental lighting significantly improved survival rate of Pachystachys lutea.Conclusion] Light-emitting diodes （LED） supplemental lighting could promote the growth of these five kinds of vertical greening plants.
