The effect of different fertilization on yield,quality and economic benefits of tomato was studied in this paper.The results showed that yield and economic benefit were increased and quality was improved by optimize fertilization and optimize fertilization combining with ameliorantCompared with farmer practical fertilization,yield of tomato and economic benefits were increased by 205% and 369%,19 400 yuan/ha and 45 200 yuan/ha in optimize fertilization and optimize fertilization combining with potassium humate and Zeolite respectively.The content of Vc was improved by 151 mg/kg and 356 mg/kg respectively;And the proportion of sugar to acid was 124 times and 165 times,respectively;The content of nitrate and nitrite were decreasedComprehensive consideration from yield,quality and economic benefits,the effects of optimize fertilization combining with potassium humate and Zeolite was best.Potassium humate was better than Zeolite,and applying potassium humate could promote tomato maturity about 5 days to 7 days.
