AI Technical Summary
Existing technologies have failed to accurately acquire soil water potential under extreme conditions, resulting in inaccurate soil moisture characteristic curves and affecting the accuracy of irrigation plans and water resource management.
By acquiring the conductivity, moisture content, and water potential sensor structural parameters from multiple monitoring points, and combining them with environmental data, the target values for moisture content and water potential are determined, generating multiple soil moisture characteristic curves, and eliminating the interference of salinity and the effects of sensor hysteresis.
It enables accurate measurement of soil water potential under extreme environments, generating soil moisture characteristic curves that are closer to the real physical state, supporting precision irrigation and water resource management.
