Salt tolerance of Suaeda salsa and its soil ameliorating effect on coastal saline soil was studied through a brine soaking experiment. It was discovered that the seeds of Suaeda salsa could germinate normally when the brine was less than 20.0 g/kg in NaCl concentration. Pot and field experiments showed that Suaeda salsa could stand brine 25.0 g/kg and 35.0 g/kg to the extremity in NaCl concentration. A planting experiment showed that planting Suaeda salsa decreased salt content in the topsoil effectively, and increased the contents of soil organic matter, N, P and K, indicating that Suaeda salsa is a kind of plant very strong in salt tolerance and its soil ameliorating effect on coastal saline soil is significant.
