Abstract： In order to determine the fertilizer effect parameters of nitrogen， phosphorus and potassium for corn cultivation and the optimal amount of fertilizer for corn fertilizer effect， the "3414" field experiment was conducted to explore the reasonable amount of fertilizer for nitrogen， phosphorus and potassium for corn production. It was concluded that treatment 12 （N1P1K2） should be the first choice for corn fertilization in the case of Liangbing town. This experiment provides a basis for farmers to apply fertilizer scientifically.
