江苏省人均耕地少,沿海滩涂盐碱地作为重要的土地后备资源其开发、利用和保护日益引起人们的高度重视.笔者初步总结了江苏沿江地区农科所及江苏省有关研究机构在滨海盐土快速脱盐改良技术、耐盐作物大规模筛选技术、沿海滩涂作物栽培关键技术以及技术沿海滩涂作物高效种植模式方面的研究进展,在此基础上提出了构建江苏沿海滩涂快速改良与高效利用技术体系的设想,包括:(1)滨海盐土评估、农林利用适宜性评价技术;(2)滨海中、重盐土快速脱盐改良技术;(3)滨海滩涂植树造林改土技术;(4)耐盐作物品种的筛选及高效规模化种植技术.%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.
