Abstract:

Cotton is the most important cash crop in Xinjiang, and southern Xinjiang is the main cotton production area, which yield accounts for 80% of the whole Xinjiang. For a long time, the planting mode of "wet sowing and dry emergence" was widely adopted in the cotton areas of southern Xinjiang, which meant that in addition to conventional irrigation during the cotton growth period, winter irrigation and spring irrigation were also needed to play a role in pressing salt and improving soil moisture during the sowing period. However, with the continuous expansion of cultivated land area and the increasing shortage of water resources, the cotton production of southern Xinjiang began to try the cultivation method in northern Xinjiang of "dry sowing and wet emergence" to grow cotton, but the overall effect was not ideal. Through the literature review, this paper tries to explore the reasons for the ineffective implementation of the "dry sowing and wet emergence" cultivation method in southern Xinjiang, and puts forward possible solution strategies on this basis.

Key words: southern Xinjiang, cotton, dry sowing and wet emergence, water saving and salt control, solution strategies
