According to the observation data of soil moisture content of the Hengshui hydrological station in 2010 ~ 2012, analyzing of soil moisture characteristics of Hengshui, researching on the change law of soil moisture of the representative area. Using actual observation data, analyzing and calculating the value of soil recession coefficient K, and fitting the in-crease quantity into calculating the empirical formula, established the forecast plan of refund quantity and increase quanti-ty, and using the data of 2013 verified it. According to the evaluation?of both plans, the prediction accuracy is 100%, and reaching grade A standard. It has a vital significance for guiding reasonable implementation of crop irrigation and ensuring agricultural production.
