Plant Growth Indicator Measuring Apparatus and Method and Plant Growth Indicator Measuring System

摘要

In the plant growth indicator measuring apparatus, the plant growth indicator measuring method and the plant growth indicator measuring system according to the present invention, the light intensity of the reflected light of the measurement object having a plurality of leaves, which is obtained by measuring with the first and second wavelengths, A growth index indicating the degree of growth of the object to be measured based on the sun angle, which is the angle of incidence of the sunlight to the measurement object at the time of measurement, and the sun direction, which is the direction of the sun relative to the measurement direction of the reflected light, Is obtained.
