Abstract

To explore suitable LED light sources for the growth and development of cherry radish, two kinds of LED light sources designed to cover the full spectrum with either staggered or linear arrangement were used as the experimental groups. Traditional white light LEDs were used as the control group to study the uniformity of the three kinds of light source and their influence on the growth of cherry radish. The results showed that the uniformity of the photosynthetic photon flux density of staggered and linear light sources was more than 86% compared to the conventional LED white light, which had a uniformity of 69.55%. Cherry radishes grown under staggered and linear light sources had significantly higher aboveground and belowground biomass compared to LED white light, showing a significant difference. No significant difference was found between staggered and linear groups.

不同LED光源对樱桃萝卜生长发育的影响

为了探索适合樱桃萝卜生长发育的LED光源，采用两种设计为交错排列和线性排列的全光谱LED光源作为实验组。以传统白光led作为对照组，研究三种光源的均匀性及其对樱桃萝卜生长的影响。结果表明:与传统LED白光的均匀度为69.55%相比，交错光源和线性光源的光合光子通量密度均匀度均大于86%;交错光源和线性光源下生长的樱桃萝卜地上、地下生物量均显著高于LED白光，且差异显著。交错组和线性组之间无显著差异。
