Abstract：Influence of distribution of soil salinity under different irrigation quota of cotton drip irrigation under film was researched from the existing cotton drip water law and impact factors.The results showed that the larger irrigation quota,the greater influence on salt movement and distribution,salt moved farther exercise in horizontal direction,soil salt content is relatively lower in the same distance,vertical direction,soil salinity was accumulated under the arable layer,the scope and extent of leaching soil salinity near the capillary were greater,the accumulation of salt greater and deeper where far from the capillary.The smaller irrigation quota,salt accumulation higher in surface soils,soil salinity leaching smaller near the capillary,the smaller and less aggregation far from the capillary.
