[Objective] In order to explore the efficient mode of water and fertilizer in protected vegetable production of Ningxia. [Method] Simple and accurate irrigation equipment was used in single greenhouse, study on the effects of different irrigation rates on growth and development of protected tomato were done in January. [Result] The average irrigation amount was 1 475 m^3/hm^2 and the fertilizer rate was 2 156.48 kg/hm^2 during whole growth period, irrigated by every 7 days, the fruit weight was 180.23 g, the yield was 160 814.81 kg/hm^2. [Conclusion] This irrigation mode saved time and labor, it could be used as a good irrigation schedule of integrative water and fertilizer in greenhouse tomato production.
