Abstract：This paper studies initially on salt and water movement affected by mineralization degree of infil-tration water under a buried trickle source through laboratory test. The results show that, at the same depth of soil,the higher the salinity of water,the greater for soil moisture and soil salinity profiles. At the same infiltration time,the higher the salinity of water,the greater for the migration distance of moist in the horizontal direction; Under point sources drip irrigation, the distance of wetting front transport is related drip time with a nonlinear correlation.
Keywords：brackish waterpoint source drip irrigationwater and salt migrationthe salinity of infiltration water
