The Development and Application of Real-time Irrigation Forecasting and Irrigation Water Decision Support System
The application of Real-Time Irrigation Forecasting and Irrigation Water Decision Support System (RTIF&IWDSS) can guide irrigation at right time and with proper quantity ,it is an important tool and main way to promote water-saving in the irrigation region and to accelerate the irrigation management toward modernization ,automation and intelligence .This paper develops a new generation of RTIF&IWDSS .Compared to the old version ,the new one has the following distinguished features:a new function is added to medium and long-term total yield and irrigation water forecasting ,with which optimal irrigation scheme can be provided by the system through water production function .Freewill date can be selected as the system running start time for next ten-day real-time irrigation forecasting ,not the first day of every ten days of one month any more .A user demand running model is supported ,in this situation ,reasonable irrigation scheme can be made automatically based on statistical users'irrigation requirements .It's more flex‐ible and friendly between user and computer as a manual intervention procedure is integrated in the system .Practical application of the system shows that it can achieve the goal of right-time and accurate-quantity irrigation and provide forceful evidence for scientific irrigation water management .
