Abstract:
In order to save water resources and improve the level of agricultural irrigation management, an agricultural irrigation intelligent decision-making tool, including agricultural irrigation planning sub-system and real-time irrigation sub-system, was developed based on the SWAT model and agricultural water balance theory. The function requirement and realization of each system were introduced from the perspective of overall design of the tool. The developed tool was applied in Guantao County. The application results showed that the simulated evapotranspiration from the agricultural irrigation planning sub-system is similar to the measured value, so this system can be used to optimize agricultural management practice. The real-time irrigation sub-system can predict the soil moisture and determine the irrigation time and amount. The tool can provide technical support for the efficient use of water resources and automation management in agricultural irrigation on county scale.
