Abstract

Taking cotton region of Shihhotze in Xinjiang as an example,this article studies on transportation law of water and salt in soil on condition of the same amount of irrigated water as well as different irrigation frenquencies.Through analysing and studing,the result shows that high frequency irrigation remarkably increases water ratio in soil under the same irrigation quota condition.The effects of leaching salt of Irrigation quota of 5 250 m3/hm2 are better than that of both of 3 300 m3/hm2 and of 3 900 m3/hm2,which can effectively control uprise of salt in soil.
