| Abstract: | Authors have conducted theoretical and practical studies on water saving in agriculture over the last decade. This paper dealt with the connotation of "Five Water Types" (air, soil, plant, surface water and groundwater) interactions in farmlands. Based on this connotation, authors discussed water interactions in soil, plant and atmosphere, as coupling system of soil-plant-atmosphere continuum (SPAC). Considering field water saving, authors presented an approach to control water fluxes through SPAC interface. Based on system integration, models for water saving were suggested for application. Data show that decreasing water consumption while increasing yield can be achieved |
