PROBLEM TO BE SOLVED: To provide a method for predicting growth of a turf grass clump in high accuracy.SOLUTION: The method for predicting growth of a turf grass clump having leaf parts and root parts, includes: a step for calculating the photosynthesis amount in which the photosynthesis amount in the turf grass clump is calculated based on the abundance of the leaf parts and the abundance of the root parts; a step for calculating a volume of distribution in which a volume of distribution to the leaf parts and a volume of distribution to the root parts when photosynthetic products corresponding to the photosynthesis amount are distributed to the leaf parts and the root parts, are respectively calculated; a step for calculating a growth amount in which a growth amount of the leaf parts is calculated based on the volume of distribution of the photosynthetic products to the leaf parts, and the growth amount of the root parts is calculated based on the volume of distribution of the photosynthetic products to the root parts; and a step for changing abundance in which the abundance of the leaf parts is changed based on the growth amount of the leaf parts, and the abundance of the root parts is changed based on the growth amount of the root parts. The calculation results in the step for changing abundance at a certain point of time are utilized in the step for calculating a photosynthesis amount at another point of time after the former certain point of time. |
