[ Objective ] To study the optimal fertilizer techniques for standardized cultivation of Plantago asiatica L. [ Method ] Through the combination design of quadric rotation, the regression model of its production and the four elements like N, P, K and organic fertilizers was set up, the optimization of the mixed fertilization was determined by the application of DPS data base. [ Result ] The regression model was founded as: 7 = 2 937.44 + 105.46X1 + 17. 06X2 + 62.69X3 + 265.18X4 -251.17X21 -80. 01 X22 -150.62X23-55.67X24 +22. 75X1X2 +22. 15X3X4. Using 3 450 kg/hm1 as the critical value of system optimization scheme, the optimal mixed fertilization was the following; N fertilizer (urea) 247.65-314.81 kg/hm2, P fertilizer (calcium superphosphate) 346.05-553.95 kg/hm2, K fertilizer (potassium sulfate) 213.3-340.425 kg/hm , organic fertilizer (digest pig manure) 32 737. 5-35 782. 5 kg/hm2. [ Conclusion] The fitting degree of this formula is good enough to reflect the relationship between its yield and N, P, K and organic fertilizers.%[目的]优选车前子规范化栽培的施肥配方.[方法]通过二次旋转组合设计,建立车前子产量与氮、磷、钾和有机肥四因子的回归模型,利用DPS数据库系统确定最优施肥方案.[结果]车前子产量与氮、磷、钾和有机肥4因子的回归模型为:y=2 937.44+ 105.46X1+17.06X2+ 62.69X3+ 265.18X4 - 251.17X21 - 80.01X22 - 150.62X23 - 55.67X24]+ 22.75X1X2+ 22.75X3X4；以产量3 450 kg/hm2作为目标,配方施肥的系统优化方案为:施氮(尿素)247.65～314.81 kg/hm2；施磷(过磷酸钙)346.05 ～ 553.95 kg/hm2；施钾(K2SO4)213.3～340.425 kg/hm2；施有机肥(腐熟猪粪)32 737.5～35 782.5 kg/hm2.[结论]方程的拟合度较好,可以用来反映车前产量与氮、磷、钾和有机肥之间的关系.
