Abstract: To determine the optimum irrigation scheme for potato drip irrigation,through the different irrigation treatment test to research potato high ridge irrigation technology.The results show that：when growing period precipitation is 102.9mm,with the same test field soil fertility and fertilization conditions,Irrigation quota reached 212.6m^3/667m^2,potato yield reach the peak;Potato rational irrigation quota is 120m^3/667m^2,when potato rational irrigation quota is 120m^3/667m^2,Potato growth period optimal irrigation times is 8-10times.
