Abstract: To improve saline-alkali soil, the halophyte was interplanted in cotton fields through drip irrigation under film. The average water content in interplanted Suaeda salsa and Salicornia europaea were larger than those in the control plot by 61.0% and 34.1% respectively. The desalinizations were 43.1% (S. salsa), 30.6% (S. europaea) and 17.2 (control plot). The K+/Na+ ratio and the soil bulk density increased, while the Cl- and soil porosity decreased, and the cotton yield increased. This suggested that interplanting halophyte in cotton fields is a good option to improve saline-alkali soil, with no requirement for much more water.
