Abstract:: ‘Qianxi’ cherry tomato was used as material,the effects of tillage methods(the direct ridging and subsoiling tillage ridging) and irrigation amount（60%,100%） on yield and quality of tomato under mulch drip irrigation were studied in order to explore the water use characteristics of tomato.The results showed that the tomato yield of subsoiling tillage ridging treatment was 1356% which was significant higher than the direct ridging;but under subsoiling tillage ridging between two treatments of 100% and 60% irrigation amounts were not significant.And the interaction effect between tillage methods and irrigation amount was obvious.The content of lycopene and vitamin C content could be increased by reducing the amount of irrigation,and soluble sugar content could be improved by deep tillage.Treatment of subsoiling with 60% irrigation amount under mulch drip irrigation was prefer,as the quality was significantly improved and the yield of tomato fruit could be guaranteed.
