Abstract

The orthogonal combination design of quadratic regression was adopted in this experiment.Effects of interaction among nitrogen,phosphorus potassium coordinating on the organism yield of silage maize was studied by field experiment.Effect of N,P,K on the organism yield of silage maize were studied quantitatively based on main and single factors effect analysis.The range of N,P,K optimal composite scheme was 308.4-365.0 kg/ha,100.1-116.0 kg/ha,65.5-89.8 kg/ha.This result provided an optimum composite scheme of N,P,K for an aimed yield.
