摘要

With three factors design of universal quadratic rotation combination, the model was established on the effects of N, P and K fertilizer on the first inflorescence yield of 'Ningfeng' strawberry under substrate culture condition. According to the results, the quadratic regression model had better simulation effect. Main effect analysis of fertilizer showed that N, P and K had different influences on fruit yield, N and K had more dramatic influences than P. Two-factor interaction analysis showed thatthere was significant interaction between two fertilizer factors that could increase the fruit yield, among which, N and K had more intensive interaction than P and K. By computer simulating, the optimum fertilization combination for 'Ningfeng' strawberry was ammonium nitrate 2.14-2.93 g plant1, sodium dihydrogen phosphate 0.43-0.73 g plant1 and potassium sulfate 2.41-3.69 g plant1, with the average first inflorescence yield of 'Ningfeng' strawberry was 84.8±0.5 g plant1.
