Study On Irrigation Model Of Jujube Under The Indirect Substurface Drip Irrigation In The Sand Tube In South Xinjiang

Water resources measure of the Earth’s surface reduce year by year and Sharply extend plants area of forestry and fruit growing make originally Water resources measure in the Tarim Irrigated Area weak, the shortage of water resources used in irrigation has been an important restraint factor in arid and semiarid areas. So, to accelerate the development of water-saving agriculture has become a very pressing task.Drip irrigation is the most advanced improve water use efficiency of one of irrigation,and the indirectly subsurface drip irrigation in the sand tube is a kind of water saving and high efficiency subsurface drip irrigation technology.It is new water-saving irrigation technique based on the surface of the water and realization way drip irrigation subsurface drip irrigation effect of,from the traditional surface drip irrigation systems (water system and surface pipeline network system) and arrangement of the surface in drops below the head of soil water-conducting device.This paper with the national natural science foundation of China (Numbers51069013) as the foundation.through the indoor water migration test and plot test, discusses the indoor water migration rule under the indirectly subsurface drip irrigation in the sand tube; survey the condition of drip irrigation root distribution law of the village;preliminary studies the suitable appropriate specification of jujube planting in the Tarim Irrigated Area under the indirectly subsurface drip irrigation in the sand tube, to influence of soil moisture、soil salinity in the root zone of jujube and Fruit quality under the indirectly subsurface drip irrigation in the sand tube.
