The results show that with the decrease of irrigation, tomato yield was reduced and water use efficiency was increased; Water use rate of grafted tomato were increased by 15.6% and 14.5% under 85% and 70% irrigation; 15% of tomato irrigation water can be saved by grafting without affecting the yield.
