Abstract
根据作物光合作用、蒸腾失水与叶片气孔开度的关系以及由土壤水分亏缺产生的作物水分胁迫信号对作物水分利用效率影响的机理，提出了控制性交替灌溉这样一种新的农田节水调控思路，阐述了这种节水调控方法的概念、原理和推广实施的方式。
The controlled alternative irrigation, a new approch for water-saving regulation in farmland, is presented in this paper, based on the relationship among photosynthesis, transpiration, stomatal size, and on the mechanism of the effect of root signals caused by water stress on crop water use-efficiency. The definition, the principle and the application methods of the controlled alternative irrigation are expounded here as well.
