| Abstract: | The theoretical basis of regulation-control of high efficient water saving oriented irrigation is discussed based on the theory of regulating-controlling redundant water for growth compensation effect of water deficit, theory for growth of crop root and corolla, theory for quality of crop by water controlling and the theory of optimal allocation of limited water method for collecting and monitoring the information of crop growing water demand and the technology of spatial scale are investigated. On this basis the research topics of theory and of crop and elevating the amount. The transformation technology of improving irrigation water use efficiency based on crop growing water demand are presented and the focus points as well as development tendency are discussed. |
