Abstract:: The experiment applied the optimal mixed design of ‘311-A’ with the ‘Fengxiang’ strawberry as the experimental material，the effect of different ratio of N，P and K on the vitamin C content formation of strawberry fruit through the way of pot experiment were studied and also the different effect of applying different NPK ratio fertilization were determined.The results showed that different NPK ratio fertilization had a very significant effect on the vitamin C content of strawberry.Through the analysis of the model，potassium was the first one which had great impact on vitamin C content of strawberry，nitrogen was the second one and phosphorus is the third one.The optimum amount of NPK in this experiment were 193,87,153.05 mg/L,and the optimum ratio was N∶P₂O₅∶K₂O=1∶0.45∶0.79.
