LED植物补光照明系统对拟南芥萌发率的效用探究

根据光谱范围对植物生长的影响以及LED的光源特性,本文设计了一种用于拟南芥生长补光的LED照明系统。该系统主要由LED照明模块、电源驱动器、调光控制器以及定时器等几个部分组成。通过对LED和荧光灯的光谱分析以及照度测试,我们可以发现LED照明系统更高效,可以实现与植物叶绿素吸收光谱峰值完全吻合。在对拟南芥种子萌发率测试实验中,可以看出LED组和荧光灯组在最终萌发率上几乎无差异,但LED组消耗的功率仅为荧光灯组的一半。实验也认为LED组中的红外模块延缓了萌发时间。

Research on the Effect of LED Lighting System for Supplementary Lighting on the Arabidopsis Seed Germination

A LED lighting system for supplementary lighting on plants is designed in the paper, according to the effects of the spectral range on plant growth and the characteristics of LED light source. This system is mainly composed of LED lighting modules, power drive, dimming controller, timer and other parts. We can find the LED lighting system is more effcient and can be achieved with the plant chlorophyll absorption spectrum peak perfect｜y based on the spectrum analysis and illumination test of the LED lighting system and fluorescent. According to the test of the Arabidopsis seed germination, we can see the final germination of the LED lighting system and the fluorescent is ahnost the same, but the energy consumption of the LED lighting system is half of that of the fluorescent lamp set. The infrared module of the LED lighting system retards the germination time.
