摘要
调亏灌溉是一种试图优化产量和提高灌溉水利用效率(IWUE)的管理策略.通过连续两年试验,在两种灌溉方式(地下和地面滴灌)和三种灌溉策略下,评估了土壤水分利用、番茄产量和灌溉水利用效率.结果表明,设定的调亏灌溉策略对作物水分管理具有一定的优势,对产量和质量的影响最小.
Abstract
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.
