Water-saving Strategies of Deficit Irrigation with Surface and Subsurface Drip Irrigation Systems in Semi-arid Region
Deficit irrigation is a management strategy that attempts to optimize yield and improve irrigation water use efficiency(IWUE).Based on two consecutive years of experiments,soil water use,tomato yield and irrigation water use efficiency with two irrigation methods(subsurface and surface drip irrigation)and three irrigation strategies are evaluated.The results show that the designed deficit irrigation strategies have positive effect on crop water management and less impact on crop yield and quality.
