Abstract

Abstract

A climatic-soil moisture-irrigation system (CSMIS) model has been built firstly by using an integrated technical approach of numerical forecast model with agricultural meteorological model. For the numerical weather forecasting section, a regional climate model is adopted to couple the atmosphere processes with ground processes. A model that was applicable to soil moisture forecasting and irrigation management forecasting in winter wheat fields was adopted as the agricultural meteorological model. The CSMIS has a higher reliability than the models in which climatic average values are used as the background fields. Meanwhile it can make quantitative forecast of regional soil moisture and provide service for irrigation management for the whole growth phase of winter wheat.
- System model;
- Soil moisture forecast;
- Irrigation management service
