采用5因素5水平二次正交旋转回归的试验方法 ,在影响马铃薯产量的诸因素中选择垄距、穴距以及氮、磷、钾施用量作为生产上的决策变量,以马铃薯产量为目标函数,所得结果通过计算机数据分析,建立了二次回归数学模型,对模型的主效应和交互效应进行分析。结果表明：在密度影响马铃薯产量中,穴距比垄距明显;氮肥、磷肥、钾肥对马铃薯产量的影响从高到低依次为氮肥〉钾肥〉磷肥,经计算模拟,氮肥、穴距和钾肥是影响马铃薯产量的主要控制因子。根据试验结果筛选出马铃薯的最佳密度和施肥方案为垄距80 cm,穴距15 cm,施氮肥（纯N）25.5 kg/667 m2、磷肥（P2O5）10 kg/667 m2、钾肥（K2O）39 kg/667 m2,氮、磷、钾的比例为1.00∶0.39∶1.53。

By using testing methods of five factors and five levels of the second orthogonal rotation regression,ridge distance,hole distance as well as nitrogen,phosphorus and potassium fertilization as the decision variables on the production of potato production target in the factors affecting potato production function,the results obtained by computer data analysis,the establishment of a quadratic regression mathematical model,the main effects and interaction effect model were analysis.The results showed that：in the density of potato production,points away from the ridge distance;nitrogen,phosphorus and potassium on potato yields in the order of NKP,by simulation,nitrogen,hole distance and potash affect the main controlling factor for potato production.Screening potato density and fertilization programs based on test results for the ridge from the ridge distance of 80 cm,hole distance of 15 cm,per 667 m2 N fertilizer（pure N） in 25.5 kg,phosphate（P2O5） in 10 kg,potash（K2O）in 39 kg.The ratio of N、P、K is 1.00∶0.39∶1.53.
