Abstract

Abstract:

In order to study the effect of different light quality ratios on celery growth in plant factory, in this study, four LED light sources with different ratio of red and blue light were selected for the experiment. The experiments showed that under the light quality ratio of red light∶blue light=3∶1, the plant height, stem diameter, leaf number, plant fresh weight, dry weight, aboveground dry weight and underground dry weight were the largest, which was beneficial to the vegetative growth of celery. The light quality ratio of red light∶blue light=3∶1 was beneficial to the increase of chlorophyll content in leaves, which could promote photosynthesis and improve the utilization rate of light energy. The light quality ratio of red light∶blue light=3∶1 was beneficial to the growth of strong seedlings and increase the yield of celery. According to the comprehensive indexes, red light∶blue light=3∶1 is the suitable light quality ratio for celery growth in plant factory.

Key words: light quality control technology, LED, celery, plant factory, red and blue combination light, seedling, yield
