Making the most of rainfall is an availability method in water saving irrigation, increasing water temperature and raising yield. Just based on this, through applying the theory of season random time series, according to the data of average monthly rainfall (1981 - 1999), the authors build up the forecasting model in the area of well irrigation rice in the Sanjiang Plain.
