Abstract: Due to the fact of less arable land per capita in Jiangsu Province, the development, utilization and protection of coastal beach as important land reserve resources have attracted much attention. The authors summarized the primary progress of fast desalination and amelioration in coastal saline soils, large- scale screening of salt-tolerant crops, key techniques of crop cultivation and efficient cropping patterns in coastal beach made in Jiangsu Yanjiang Institute of Agricultural Sciences and relevant research institutions. Based on them, constructing a technique system of fast amelioration and efficient utilization of coastal beach in Jiangsu was proposed, including: (1) assessment of coastal saline soil and suitability of agriculture and forestry utilization of saline land; (2) fast desalting and amelioration of medium and heavy saline soil; (3) afforestation technology of coastal beach; (4) screening of salt tolerant crop varieties and developing high-efficient and large-scale cropping techniques.
