Abstract：Using the quadratic orthogonal regressive design with three factors, a soilless culture experi-ment was conducted to study the effects of nitrogen, phosphorus and potassium concentrations on tomato yield and lycopene content.The regression models were established, and the single and coupling effects of the three experimental factors were studied.The results showed that rational fertilization could effectively increase toma-to yield and lycopene content.Under the conditions of this experiment, high tomato yield and lycopene content could be obtained at 9.970~10.860 mmol/L N, 1.364~1.635 mmol/L P and 5.113~5.158 mmol/L K.
