Abstract：Inorder torealizetheeficientuseoffertilizerintheproductionofradish，theradishvarietyGuibai No.1 wasused as the test material， a ?3414， field experiment was performed， the conventional fertilization（N P2O5 225kg?hm-2 K2O225kg hm-2 was used .The yield， growth characteristics and quality were measured.The optimal fertilizationformulaofradish plantingwas determinedbyfitingthefertilizerbenefit functionequation.Theresultsshowed that the applicationofnitrogen，phosphorus，andpotassumfertilizershadasigniicanteffectonincreasing theyieldofradish. The yield of N2P1K2 treatment（N 225kg?hm-2 0 P2O5112.5kg?hm-2 K2O225kg?hm-2） wasthe highest（ 88263.53kg?hm-2） which significantly increased by 55.46% compared with N0P0K0 treatment （N0kg?hm-2 P2O50kg?hm-2 K2O 0kg?hm-2） and the yield of N2P1K2 treatment significantly increased by 13.97% compared with conventional fertilization. Combined application of nitrogen，phosphorusand potassumcould notonly promotethe growth and developmentof singleradish plant，butalsoincrease the moisturecontentandsolublesolidscontentoftheradish，but the efectoncrude fibercontent Was not significant.The most suitable fertilization regimen for radish in Guibei area was 18.75-206.25kg?hm-2 for Nand P2O5， 112.5-225kg?hm-2 for K2O ，according to the fertilizer efficiency model and frequency analysis method.
