Plant characteristics of plant populations in the growth process of the germination process (from the sowing to the immediate seedling growth) in the artificial light plant plant.Specifically, based on the image information 2a, the environmental factor information 2B, the gene characteristic information 2C and the artificial operation information 2D, the plant characteristic information in the growth process of the germination stage is continuously measured in a non-destructive manner and the two-dimensional distribution of the plant characteristics is calculated.In addition, the physiological responses of plant populations grown in the closed environment are continuously measured, and the two-dimensional distribution of the environmental factor information, the temperature, the difference in the nutrient solution, the rate of solution, the temperature of the solution, the pH and the electrical conductivity are continuously measured.
