| Abstract: | The potato＂3414＂ fertilizer experiment was carried out and in Irrigation Districts Along Yellow River of Jingyuan county.The results showed that a medium level of the soil nutrients.The production and fertilizer by the ternary quadratic regression equation fitting results showed that potato yield had significant effect on the nitrogen（N）,phosphorus（P2O5） and potash（K2O）,the yield reached 40 735.5 kg/hm2,the maximum amount of nitrogen,phosphate and potash in soils were 240.0 kg/hm2,99.0 kg/hm2,99.0 kg/hm2,respectectly;the best amount of N,P2O5 and K2O in soils were 199.5 kg/hm2,82.5 kg/hm2,81.0 kg/hm2,respectectly,the potato production was 40 342.5 kg/hm2. |
