Abstract：The tomato variety Jinpeng 11 -8 was used as substrate culture material .Under the same supply level of nutrient elements in nutrient solutions , we set 6 concentrations including 0, 50, 100, 150, 200 and 250 mg/L of fulvic acid to study the effect of fulvic acid on yield , growth and quality of tomato.The re-sults showed that the single plant yield of tomato was significantly improved under 150 ～250 mg/L of fulvic acid.When the concentration of fulvic acid was in the range of 100 ～150 mg/L, the growth and development of tomato plants was promoted.When the concentration of fulvic acid was in the range of 100 ～200 mg/L, the contents of soluble sugar, VC and lycopene increased significantly , and the nitrate content was effectively con-trolled.Therefore, the optimum concentration of fulvic acid was 100 ～200 mg/L under this experiment condi-tions.It could provide a reference for the high quality and efficient production of tomato grown in protected cultivation.
