Abstract

Three-year-old ‘summer black’ 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 1000，1200，1400 times amino acids chelate calcium 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 external quality and intrinsic quality of ‘summer black’ grape. Compared with the control, spraying 1000 times amino acids chelate calcium had the most significant effect. The fruit weight of the grape increased by 22.5%, vertical diameter increased by 8.8%, transverse diameter increased by 10.8%, the fruit firmness increased by 35.7%, the content of the titratable acid decreased by 23.2%, the content of soluble sugar increased by 38.7%.The results of this experiment provided some guidance for supplementing calcium and improving fruit quality in grape production.
