Effects of Different Irrigation Amounts on Water Consumption and Water Utilization Efficiency of Greenhouse Cucumber

[Objective] This paper aimed to investigate the effects of different irrigation amount on water consumption and water utilization efficiency of greenhouse cucumber.[Method] Under the condition of drip irrigation with different water amount in sunlight greenhouse of the arid areas in Ningxia,the soil water was measured and the water consumption of crop was calculated.[Result] When irrigation amount was 563 mm,the water consumption as a whole gradually increased with the delay of growth period,reached peak during the thriving stage of fruit setting,and then gradually declined;in each treatment,the daily water consumption increased with the increasing of irrigation amount during every growth period.However,the consumption of soil moisture reduced with the significant increase of irrigation.563 mm of irrigation amount could meet the water requirements of cucumber and began to add water to soil,and water utilization efficiency could reach 33.4 kg/m3.[Conclusion] The research had provided theoretical basis for water management in the production process of greenhouse cucumber.
