中文摘要：

掌握水分调控方式对于农田的有效耕作具有重要的意义。作物水分的消耗主要用于叶片的蒸腾和光合作用，把握这2个重点对于节水模式和灌溉方式具有一定的指导意义。该文综述了农田土壤水分生态过程及其调控，植物水分生态过程及其调控，土壤-植物-大气连续系统水分生态过程及其调控，并展望了作物根系吸水作用和耐旱植物的培育，为今后农业可持续发展提供理论依据。

英文摘要：

Water deside way is a great significance to the effective cultivation of farmland.Crop water con？sumption is mainly used for leaf transpiration and photosynthesis,grasp the two key for water saving irriga？tion patterns and has a certain guiding significance. This paper summarized the farmland soil water ecologi？cal process and its regulation,plant water ecological process and its regulation,the soil-plant-atmosphere continuous system water ecological process and its regulation,and put forward to analyze the water effect of crop root,breeding of drought-enduring plant,and provide theoretical basis for agricultural sustainable de？velopment in the future.
