Abstract：To improve the quality of tomatoes in Miyun,three fertilizers including medium-trace element water-soluble fertilizer,steviol glycoside biostimulant fertilizer and macroelement water-soluble fertilizer were topdressed at the fruiting stage,with clear water as the blank control(CK).The yield and quality indices(soluble sugar,titratable acid,sugar-acid ratio,vitamin C,etc.)were determined to compare the improving effects of different treatments on tomato yield and fruit quality.The results showed that compared with CK,macroelement water-soluble fertilizer application increased the contents of soluble sugar,soluble solids,lycopene and soluble protein in tomato fruits by 0.14％,0.24％,5.93％and 1.8％,respectively.Topdressing with steviol glycoside biostimulant fertilizer increased the contents of soluble sugar,soluble solids and lycopene by 0.45％,0.64％and 4.46％,respectively.Topdressing with medium-trace element water-soluble fertilizer increased the contents of soluble sugar,soluble solids,lycopene and VC by 0.37％,0.34％,6.37％and 9.67％,respectively.In conclusion,medium-trace element water-soluble fertilizer treatment had a significant promoting effect on all the four core quality indices of tomato fruits.It is suggested that the magnesium-cobalt medium-trace element water-soluble fertilizer formula be prioritized in production practice,and subsequent large-scale field experiments will be conducted to further verify its application effect.
