The invention tracks and automatically evaluates plant traits of 'individuals of plant canopy' in a growth process of a germination period (from sowing until immediately prior to primary seedling culture), at a plant factory with artificial lighting. Specifically, a two-dimensional distribution of the plant traits is calculated by non-destructively and continuously measuring plant trait information in the growth process of the germination period, on the basis of image information, environmental factor information, genetic characteristic information, and management information. In addition, physiological performance reactions of the individuals of plant canopy cultivated in an environmentally-controlled closed space are continuously measured, and measurements are continuously taken of the two-dimensional distribution of the environmental factor information, and items such as temperature, vapor pressure deficit, nutrient solution percentage, nutrient solution temperature, pH, and electric conductivity.
