| Turpan-Hami Basin as one of the hottest regions in China has a temperate continental climate. Thanks to its abundant solar energy, grapevines become the key in local tree fruit industries. Located in dry inland and characterized by irrigated agriculture, the desert oasis is in water crisis, which becomes constraint for the regional agriculture and sustainable development.By traditional irrigation method, the rated quantity is 1800m3/mu. Among which 90% is consumed by grape trees. Consequently, it is urgent to adopt water-saving irrigation techniques and study water consumption characteristics of plants to promote agriculture development and protect environment especially in water-shortage Turpan-Hami Basin.The thesis aims to improve water use efficiency of fully grown grape trees by studying their laws for water consumption and water critical potential to meet their water demands as well as improved drip irrigation. It also works out the drip irrigation regulations, provides technical supports for the extreme dry area and puts forward field water management methods, which well coordinates the relations between high yield and water saving.
