Research on the application of LED

- Jul 14, 2018 -

LED as a supplementary lighting plant photosynthesis too much heat generated by the study of traditional artificial light, such as added using LED lighting and hydroponic system, air can be recycled, too much heat and moisture can be removed, electricity can be efficiently transformed into effective photosynthesis radiation, eventually into the plant material.

Studies show that LED lighting can increase the growth rate and photosynthetic rate of lettuce by more than 20%. It is feasible to use LED in plant factories. Compared with fluorescent lamps, the mixed wavelength LED light can significantly promote the growth and development of spinach, radish and lettuce, and improve the morphological index. It can maximize the accumulation of beet biomass, the accumulation of beet element in the hair root is the most significant, and the accumulation of sugar and starch in the hair root is the highest.


Compared with metal halide lamp, grew up in accord with pepper, basil plants under the wavelength of LED, the stem and leaf of significant changes in the morphology, anatomy and the optical density increased, plant photosynthetic rate increased. Compound wavelength LED can cause the stomatal number of marigold and sage to increase.
