摘　　要：根据甘肃省干旱区的特殊自然地理条件，从土壤水分运动的基本方程出发，根据小麦各生长期的需水规律，建立了喷灌条件下春小麦田间水分运动模型，并对模型方程的初始条件与边界条件作了进一步的演化，对喷灌条件下水分运动规律进行了模拟试验研究，得到了适合甘肃自然条件的节水喷灌制度。According to the exceptional nature geographical condition of the arid region in Gansu province, the hydrodynamic motive model in spring wheat field is build by the basic equation of soil water. The initial stages and boundary condition of this model have more evolution in this paper. This model was applied to obtain the hydrodynamic motive rule and save water system of sprinkling irrigation in Gansu province.
