Effects of Different Irrigation Amount on Yield and Quality of Greenhouse Tomatoes

In order to determine the proper irrigation amount of summer tomatoes, taking drip irrigation in green house, 5 irrigation volume including 990 m(3)/hm(2), 1485 m(3)/hm(2), 1980 m(3)/hm(2) (CK), 2475 m(3)/hm(2), 2970 m(3)/hm(2) were set, and the effects of different irrigation amount on the yield and quality of tomato in greenhouse were studied. The results showed that with the increase of irrigation amount, the soluble solid content, titratable acid content, Vc content and irrigation water use efficiency of tomato decreased. In treatment T1, T4, T5, yield decreased by 26.3%, 6.5%, 15.8%. In treatment T2, the yield decreased by 1.9%, while the irrigation water use efficiency increased by 20.8%, and the soluble solids content, titratable acid content and Vc content increased. It was concluded that the optimum irrigation amount was 1485 m(3)/hm
