[0002] Crop water stress inevitably exists in various agricultural production environments. Water shortage will affect crop growth and thus reduce crop yield. Crop water shortage is usually described by indicators such as soil moisture and crop stem and leaf water potential, stomatal conductance, and transpiration rate. Existing technologies can monitor crops through different types of sensors, and combining data from different sensors can provide a more comprehensive understanding of the real-time situation of crops.
