Field experiment conducted on the different types of soil in the east, middle and west parts of Jilin province showed that the N, P and K application mode could be expessed by the ,quadratic equation.Y=ax. ＋bx＋c, and through this mode by the maize and fertilizer price, we made sure that the optimum fertilizer rates on the alluvium soil of the east part of Jilin province was N 192 kg/ha, P2O5 56 kg/ha and K2O 33 kg/ha respectively, and the optimum fertilizer rates on the black soil of the middle part of Jilin province was N 133 kg/ha, P2O5 38 kg/ha and K2O 47 kg/ha respectively, the optimum fertilizer rates on the light chemozem soil of the west part of Jilin province was N 59 kg/ha, P2O5 65 kg/ha and K2O 51 kg/ha respectively.
