Digital plant canopy moisture evapotranspiration data mining system

A digital plant canopy moisture evapotranspiration data mining system disclosed by the present invention comprises a main control unit, the main control unit is connected with a detection unit used for detecting and acquiring moisture evapotranspiration data of a plant canopy position, and the detection unit comprises a leaf physiological detection module used for detecting leaves of the plant canopy position, obtaining the influence of the environmental factors on the physiological process of the leaves; the leaf physiology detection module comprises a leaf temperature detection module; by means of the design, on the basis that an existing conventional water evapotranspiration detection means is reserved, corresponding analysis detection can be conducted according to leaves of different plants, obtained leaf water evapotranspiration data are more accurate, meanwhile, the situation affecting leaf water evapotranspiration is further detected, and the detection accuracy is improved. Compared with an existing de
