Application Research of Integrative Water and Fertilizer in Xiangyuan Greenhouse

[Objective] Through the application of integrative water and fertilizer in greenhouse tomato, the optimum irrigation and fertilizer amount were determined.[Method] 2 treatments were designed?under the same management conditions. Integrative water and fertilizer technique and conventional irrigation were compared.[Result] The comparison of different irrigation methods test showed that there were an increasing yield rate of8.8%, saving water rate of 33.5% and saving fertilizer rate of 33.5%. [Conclusion] Tomatoes best irrigation amount was 3 750 m3/hm2 and nitrogen, phosphorus potassium fertilizer content were 420, 165, 75 kg/hm2 respectively.
