为了探索适合北方寒区马铃薯（Solanum tuberosum L.）种植的测土配方施肥技术，对比了依据不同参数建立的施肥模式对马铃薯产量及经济效益的影响。依据“3414”试验获得的数据，采用土壤有效养分校正系数法、地力差减法及回归方程拟合求得的一元二次方程建立了3种施肥模式，对比试验表明，通过回归方程即氮（N）：Y=25400.7+166.5 N-0.35 N2（R2=0.958），磷（P）：Y=35669.7+181.7 P-2.2 P2（R2=0.948），钾（K）??Y=32714.5+107.2 K-0.4 K2（R2=0.997），建立的最施肥模式获得的产量及经济效益分别较当地常规施肥处理高7.8%和2138元/hm2，适合北方寒区马铃薯栽培。

In order to explore the formula fertilization by soil testing technique adaptable to the cultivation conditions in north cold region, the effect of fertilization pattern constituted according to different parameters on the yield and economical benefit were compared. According to the data obtained from“3414” test, the fertilization patterns were achieved by soil available nutrient correlation coefficient, land fertility subtraction method and unary quadratic equation with one unknown number fitting by regression equation, respectively. The comparing experiment showed that by the best fertilization pattern constituted by regression equation, via the equations (N):Y=25400.7+166.5 N-0.35 N2 (R2=0.958), (P):Y=35669.7+181.7 P-2.2 P2 (R2=0.948), and (K):Y=32714.5+107.2 K-0.4 K2 (R2=0.997), the yield and economical benefit were, respectively, 7.8%and 2 138 CNY/hm2 higher than the local general fertilization pattern. So unary quadratic equation with one unknown number was much more suitable for potato production in north cold region..
