Abstract
The 3414 design of quadratic regression was adopted in this experiment.Effects of interaction among nitrogen,phosphorus potassium coordinating on the yield of rice were studied in Panjin.The effect of N,P and K on the yield of rice was studied quantitatively based on main and single factors effect analysis.The optimal composite scheme of N,P and K was 260~320 kg/hm2,150~200 kg/hm2,70~100 kg/hm2.This result provided an optimum composite scheme of N,P and K for target yield.
