Abstract: Three-year-old 'ruby seedless' grapes were used for trial material to study the effects of spraying with the different concentrations of calcium fertilizer on grape fruit external quality and intrinsic quality.Fruits were sprayed 0.1%, 0.2%, 0.3% Calcium nitrate solution during the fruit color-changed period, and fruits were sprayed clear water for the check.The results showed that the different concentrations of calcium fertilizer improved the appearance quality and intrinsic quality of the 'ruby seedless' grape fruit.Compared with the control, spraying 0.3% calcium nitrate solution had the most significant effect.The fruit weight of the grape increased by 23.4%, the fruit firmness increased by 83.6%, the content of the titratable acid decreased by 24.7%, the content of soluble solids increased by 16.33%, the content of soluble sugar increased by 27.53%, and the content of Vc increased by 19.0%.The results of this experiment provided some guidance for supplementing calcium and improving fruit quality in grape production.
