First and second-year assessments of the rapid reconstruction and re-vegetation method for reclaiming two saline-sodic, coastal soils with drip-irrigation

摘要: Soil salinity, sodicity and saline groundwater are major constraints to the cultivation of landscape plants along oceanic coasts. A sustainable approach for reclaiming saline-sodic soils in coastal environments is evaluated. tillage, phased water management based on soil matric potential under drip-irrigation, installation a gravel-sand layer were used. Field trials using method showed that proposed had advantages considerable conservation, more effective salt leaching successful re-vegetation with desired species. Severely became non-saline within 0-40 cm profile after one year moderately 0-120 depth two years. The can rather quickly create an attractive maintain good plant growth. Plants representing nearly 30 species, including some sensitive salinity proposed. Plantings survival up 90% This demands less water, improves ecological environments, will inspire development areas.
