Abstract: Xinjiang is located in the Northwest Arid Areas,a serious shortage of water resources,to solve the problem of cotton winter irrigation in arid areas,clear drip irrigation cotton fields of Northern Xinjiang winter irrigation irrigation quota under different irrigation methods and its influence on water,salinity and temperature,through field experiment,the soil moisture,salt,and irrigation quota and so on comprehensive control,and the not winter irrigation cotton as the control (CK),set the drip irrigation and flood irrigation mode,five gradient irrigation quota (1 200,1 800,3 600,3 000,3 600 m3/ha) winter irrigation experiment was carried out. Winter irrigation in drip irrigation,flood irrigation,and through the contrast and the different irrigation quota on the analysis of the change of water,salt,the results showed that the winter irrigation on soil water and salt distribution and content all had certain influence,the size of the drip irrigation and flood irrigation with the increase of the irrigation quota,soil water and salt deepen influenced depth,irrigation quota on soil water and salt in 1 200-2 400 m3/ha influenced depth at 150 cm,irrigation quota on soil water and salt in 3 000-3 600 m3/ha influenced depth of 300 cm,drip irrigation and flood irrigation were effective leaching upper and lower soil salt content; Compared with the flood irrigation method, the soil water infiltration uniform of drip irrigation mode and the rinsing salt were obvious. Comprebensive consideration,under the condition of winter irrigation,the superiority of different irrigation methods was drip irrigation > flood irrigation > not winter irrigation; Big ration irrigation was better than small quota of irrigation(1 200-2 400 m3/ha) water,salt and salt leaching pressure effect was more obvious; Synthesis of the complexity of the salt and water movement and salt leaching effect,preliminarily determine the drip irrigation quota under way was 3 000 m3/ha is advisable.
