摘　　要：从土壤条件、农工技术素质、自动化控制技术、作物种植模式和水肥耦合效益等方面分析了滴灌技术的适应性问题。生产数据显示,盐碱地上采用滴灌技术得到的节水效率远低于非盐碱地上的效果;当前自动控制滴灌技术的主要问题是控制设备不适应其工作环境,人们对相应的管理要求认识不准;目前滴灌技术的主要优势是便于实施水肥耦合灌溉制度,有利于作物大幅增产。The conditions for using drip irrigation technique effectively were analyzed from the aspects of soil state,qualities of farmers,automatic control technique,and the benefit resulting from fertigation.Data surveyed in fields showed that water-saving efficiency resulting from the drip irrigation in saline-alkaline land was lower than that in non-saline-alkali land;the control equipment of the automatic drip irrigation system was inadaptable to operating condition and the operators didn＇t realize clearly the operating requirements;but the drip irrigation technology was adaptable in fertigation that promoted crop yield.
