英文摘要A field experiment was carried out to evaluate an integrated use of saline water for saline soil reclamation around Bohai Bay in China. A landscape shrub (Caryopteris x clandonensis 'Worcester Gold') was cultivated and irrigated with five water salinities (ECi): 0.8, 3.1, 4.7, 6.3, and 7.8 dS m(-1). Drip irrigation was scheduled by evolving soil matric potential thresholds of -5, -10, -15, and -20 kPa in 4 years. A gravel-sand layer as subsurface drainage was installed at 1.0 m depth. After 4 years, the extremely saline soil (ECe of 27.8 dS m(-1)) for 0-1.0 m depth was reclaimed to moderately saline soil (ECe of 4.1-7.2 dS m(-1)). The decreases in survival rate, growth, and shoot dry weight of the plants as increasing ECi were observed. To achieve a relative survival rate of >50%, the ECi thresholds for plants were 7.8, 6.9, 5.5, and 5.3 dS m(-1) for the 4 years, respectively. The quantificationally estimating root zone drainage and salt leaching efficiency indicated that more efficient salt leaching offered by ECi up to 3.1 dS m(-1) in comparison with freshwater with ECi of 0.8 dS m(-1) and less efficiency occurred at ECi > 6.3 dS m(-1). The plants strongly responded to the different soil water and salinity regime in the dynamic leaching process, as thus it is recommended to use an inter-seasonal evolving matric potential threshold of -10 kPa for dry season of the third year, -15 kPa for rainy season and following dry season for providing optimized soil water and salinity condition.
