摘　　要：为了量化各种潜在水源对作物的贡献比例、定量研究农田水分利用特征和水分转换规律,分析与总结了国内外作物水分来源解析、旱涝胁迫条件下作物根系吸水等方面研究现状及发展动态,提出下一步可开展旱涝胁迫条件下作物根系对不同水源利用量研究。从理论层面剖析了旱涝胁迫环境下作物根系吸水机理,对于理解不同水源对植物根系吸水量的贡献,以及农业节水灌溉和生态系统水文过程具有重要意义和实用价值。In order to quantify the contribution ratio of various potential water sources to crops and quantitatively study the characteristics of farmland water use and water conversion,the research status and development trends of crop water source analysis and crop root water uptake under drought and waterlogging stress at home and abroad were analyzed and summarized.It is proposed that the next step can be carried out to study the utilization of different water sources by crop roots under drought and waterlogging stress.The mechanism of crop root water absorption under drought and waterlogging stress was analyzed theoretically.It is of great significance and practical value for understanding the contribution of different water sources to plant root water uptake,as well as agricultural water-saving irrigation and ecosystem hydrological processes.
