Abstract

The invention relates to a method for determining the universal light spectrum of various plants and a plant light spectral interval. A universal light source spectrum of various plants is obtained by processing data through plant absorption spectra. The method comprises the following steps: classifying data at different wavelengths in the spectral data of various plants; averaging data of different plants at the same wavelength; using the data obtained in step II as a universal light source spectral numerical value of various plants at the wavelength; and combining the average values obtained at different wavelengths to obtain a novel plant light source spectrum. According to the method, the difference of different plant absorption spectra is uniformly considered, so that the spectrum of the light source can conform to the absorption spectra of a majority of plants as far as possible, fewer plant light sources can conform to the absorption spectra of various plants, and when a variety of plants are planted, the number of used light sources can be reduced, and therefore, the production cost and the production complexity are reduced.
