摘　　要：[目的]为解决生产上存在的盲目和过度施肥现象,提高肥料利用率。[方法]以紫色马铃薯材料KX-5为试材,采用"3414"完全实施方案设计,研究了西南二季作区春季紫色马铃薯的施肥模式。[结果]紫色马铃薯产量(Y)与肥料水平(X1-N,X2-P2O5,X3-K2 O)的最优三元二次肥料效应函数方程为Y=1 352.67-89.78X1+14.17X2+144.98X3-8.03X1 2-5.07X2 2-3.83X3 2+36.46X1 X2-2.54X1 X3-12.95X2 X3,获得最佳产量的氮、磷、钾施肥量为61.80、73.65、131.25 kg/hm2。[结论]该研究可用来指导当地紫薯生产经济施肥。[Objective] The research aimed to solve the problems of blind and excessive fertilization and improve the utilization rate of the fertilizer.[Method] Purple potato KX-5 was taken as material.3414 full implementation plan design was adopted to study the fertilization model of purple potato in southwest second quarter area in the spring.[Result]Optimum ternary quadratic equation of fertilizer effect function of the yiele of the purple potato(Y)and fertilizer level(X1-N,X2-P2O5,X3-K2O) was Y=1 352.67-89.78X1+14.17X2+144.98X3-8.03X12-5.07X22-3.83X32+36.46X1X2-2.54X1X3-12.95X2X3.And the application amount of N,P2O5 and K2O was 61.80,73.65 and 131.25 kg/hm2.[Conclusion] The research could provide the guidance for economic fertilization of purple potato production in the local area.
