Abstract In order to control the soil salinization,a series of tests were carried out on a piece of saline-alkali land in Xiayedi irrigation district of Manasi in Xinjiang, where the subsurface drainage was arranged based on the existing rows and farm ditchs. The salt controlling effect in the drainage system combined with the subsurface drainage and the ditch drainage in the saline-alkali land with drip irrigation under mulch was studied experimentally. Set the sampling points at 8 m,16 m,and 24 m from the ditch drainage and the subsurface drainage respectively. The underground water table and soil salinity at depths of 0-200 cm were observed, during the different seasons of 2012-2014. The results show that both the subsurface drainage and the ditch drainage can control the underground water table. ranging from 1.6m to 2.2 m in the ditch draining area and ranging from 1.5m to 2.2m in the subsurface drainage area. Compared with the year 2012, soil total salt at each sampling point at depths of 0-200 cm in the subsurface drainage area decreased by 42.99%,36.84% and 24.41% in 2014. At the root layer, soil total salt at each sampling point decreased by 50.34%,40.70% and 30.76%.For the ditch drainage, soil total salt at each sampling point at depths of 0-200 cm decreased by 46.85%,38.12% and 30.80%. At the root layer, soil total salt at each sampling point decreased by 54.88%,43.39% and 33.21%. This study provides a reference for saline-alkali land management in arid and semi-arid areas.
