Abstract
The present invention relates to the technical field of plant cultivation through artificial light, and particularly provides a light environment method for plant cultivation through full-artificial light to provide a full-artificial light source for plant growth. The light source includes a light wave with a waveband of 620 nm to 760 nm, and the number of photons of the light wave of 620 nm to 760 nm accounts for 64% to 76% of the total number of photons of the light source. Compared with traditional light sources, such as existing fluorescent lamps and high-pressure sodium lamps, the present invention adopting a mode of light source proportion and light source combination can greatly improve the yield of the plant. Compared with a traditional LED lamp light source proportion scheme, the light source proportion scheme of the present invention has the advantages that the waveband of a selected light source is more precise, the influence caused by other plant growth parameters is small, and a more targeted effect is achieved in the process of promoting plant growth. By using the precise combination and proportion of the precise waveband of the light wave, a peak wavelength and a pho…
