The Development and Application of Irrigation Water Decision Support System Based on Real-time Weather Information

Irrigation Decision Support System Based on real-time weather information can implement automation and intelligent irrigation management through the combineation with irrigation forecast model.This paper describes the mathematical model, the system structure and functions of irrigation decision support system based on real-time weather information.Compared to existing irrigation management system, this system improves irrigation scheme development process, increases the real-time weather forecasts irrigation schemes correction function, and provides intelligent human intervention functions.In addition, the system combines the features of irrigation management and data analysis techniques, the use of regression analysis to solve the problem of missing data or errors due to extreme weather to provide accurate irrigation decisions.Practical application shows that this system has high accuracy and usefulness, and can provide forceful scientific means for irrigation water management.
