A method for promoting the accumulation of secondary metabolites of cannabis is disclosed. The method comprises the step of adding an irradiation of green-yellow light, which has a peak wavelength at 505-590 nm, into the indoor growing environment of cannabis to improve the level of cannabidiol (CBD), secondary metabolites in cannabis. While maintaining the light intensity and other growth conditions, the yield and/or level of CBD, secondary metabolites in cannabis, can be increased by up to 11.04%.

Method for promoting accumulation of secondary metabolites in cannabis

A method for promoting the accumulation of cannabinoid substances is disclosed. The method comprises the step of adding an irradiation of green light, which has a peak wavelength at 505-526 nm, into the indoor growing environment of cannabis to improve the levels of tetrahydrocannabinol (THC) and cannabidiol (CBD), cannabinoid substances in cannabis. While maintaining the light intensity and other growth conditions, the yields and/or levels of THC and CBD, cannabinoid substances in cannabis, can be increased by up to 21.35%.

Light regulation method for promoting accumulation of cannabinoid substances

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 photon proportion, the present invention can more precisely control a plant growth effect, and thereby promoting the plant growth.

Light source for indoor plant cultivation

An LED plant growth lamp spectrum, the spectrum including: a light wave of 500-599 nm and a light wave of 700-780 nm, where a ratio of the number of photons in the range of 500-599 nm to the number of photons in the range of 700-780 nm is 0.9-1.6:1. The LED plant growth lamp spectrum promotes indoor cultivation and growth of plants, and helps to increase the yield of medicinal components per unit area and per unit time in the factory production.
