Abstract To explore the effects of drip irrigation with Yellow River on the growth, yield and quality of fieldgrapes,based on the comparative experiment of 3 years Crimson grape irrigated with Yellow River water and groundwater in the whole growth period under field conditions, the growth, yield and fruit quality of the Crimson grape was measured, and the growth indicators under two water quality drip irrigation conditions of grape in the whole growth stage and yield was analyzed. The results show that the Yellow River water can significantly affect the growth and development of Crimson grapes. Irrigation with the Yellow River water significantly promoted the growth and development of new shoots, fruit expansion, fruit shape index and hardness. The soluble solids and soluble sugar content of grapes under drip irrigation of the Yellow River were 21.26% and 13.59% higher than that of groundwater drip irrigation, respectively. The titratable acid content of grapes decreases by 15.79% under the same condition. Drip irrigation with Yellow River water has positive significance in promoting the growth of new shoots, increasing the yield and improving the nutritional quality. This experiment can provide scientific basis and theoretical reference for the development of drip irrigation of grapes.
