2021-8-7  A gravel-sand layer as subsurface drainage was installed at 1.0 m depth. After 4 years, the extremely saline soil (EC e of 27.8 dS m −1) for 0–1.0 m depth was reclaimed to moderately saline soil (EC e of 4.1–7.2 dS m −1). The decreases in survival rate, growth, and shoot dry weight of the plants as increasing EC i were observed.
