Abstract: Based on the controlling experiments of soil water and nitrogenous fertilizer for winter wheat, the influences of soil water and nitrogen on winter wheat yield and the interaction between soil water and nitrogen are analyzed by means of mathematical statistics and mathematical analysis. The model of soil water and fertilizer for winter wheat is established for sandy loam. Throuhg the testing in production, the model could be used in agricultural production.-
