Experiments of bioremediation and control were conducted with the alkali meadow grass planted in saline soil for 3 years. Contrasted with control group, topsoil desalination rate was up to 77.00%; pH value decreased 0.25 pH unit; soil bulk density decreased 0.14 g/m^3; total porosity increased by 5.29%; soil aggregate structure increased by 23.14%; soil water content increased 70.30 g/kg; average triennial alkali grass yield was 36000 kg/hm^2.
