摘　　要：以"泰山5号"马铃薯为研究对象,采用"3414"肥料试验设计开展早熟马铃薯的氮、磷、钾肥料效应研究,通过建立氮肥、磷肥和钾肥三因子与产量的回归数学模型,研究马铃薯最高产量、收益等条件下的最佳施肥量。结果表明,施肥增产效果上钾肥>氮肥>磷肥;一元二次肥料数学模型优于三元二次和二元二次肥料数学模型;N_2P_2K_2处理下产量和收益最高,分别为2 685.57 kg/667 m^2、6 485.22元/667 m^2。综合比较产量、收益得出最佳肥料用量,氮肥24.00~25.97 kg/667 m^2、磷肥4.00kg/667m^2、钾肥34.00~45.16 kg/667 m^2,比例约为2.50∶0.40∶3.96。Taking‘Tai Shan 5＇potato as the object, using‘3414＇fertilizer experiment design, the optimal fertilizer application under the highest yield and net income was studied by establishing a regression mathematical model of N, P, K and potato yield regression mathematical model. The results showed that the effect order of N, P and K fertilizer was KNP. While the mathematical model of a quadratic fertilizer was better than the ternary and binary quadratic fertilizer mathematical model.The yield and net income reached the highest under N2P2K2 treatment for 2 685.57 kg/667 m^2, 6 485.22 Yuan/667 m^2, respectively. Compared the yield and net income, the optimum fertilizer rate of potato identified as N 24.00-25.97 kg/667 m^2, P 4.00 kg/667 m^2, K 34.00-45.16 kg/667 m^2, the most suitable ratio of N： P：K was 2.50∶0.40∶3.96.
