中文摘要:
      在分析我国水资源紧缺状况与农业节水发展趋势的基础上,依据作物生长冗余调控与缺水补偿效应理论、根冠通讯理论、作物控水调质理论和有限水量最优分配理论,分析了基于生命需水信息的作物高效节水调控的理论基础。对作物生命需水信息的采集与监测方法及时空尺度转换技术进行了探讨。概括出了基于生命需水信息的作物高效节水调控技术八个方面的研究内容,分析了基于生命需水信息的作物高效节水调控理论与技术研究的难点和创新点以及进一步研究的趋向。
英文摘要:
      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 of crop and compensation effect of water deficit, theory for growth of crop root and corolla, theory for elevating the quality of crop by water controlling and the theory of optimal allocation of limited water amount. The method for collecting and monitoring the information of crop growing water demand and the transformation technology of spatial scale are investigated. On this basis the research topics of theory and 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.
