辽河三角洲盐渍土是在三角洲沉积与滨海沉积的母质上发育而成的。区内盐渍土的主要类型有潮滩盐土等六类。在开田筑渠、引淡排咸的条件下,以种植水稻为主体,形成了水土资源综合利用的模式;同时构建了田间工程纵向布置、暗管排水等完善的综合技术体系。在新的历史阶段及资源条件下,发展盐土经济与加强次生盐渍化防治是区域内生产与经济发展的主要方向。
Saline soil in the Liaohe Delta was developed on the parent material of delta deposition and coastal deposition. The main types of saline soil in the area include tidal flat and salt soil. Under the conditions of open fields and ditches, dips and salts, the mode of comprehensive utilization of water and soil resources has been formed with the cultivation of rice as the main body. At the same time, a comprehensive and comprehensive technical system of vertical layout of field works and underground pipe drainage has been established. In the new historical stage and resource conditions, the development of salt and earth economy and the strengthening of secondary salinization prevention and control are the main directions of production and economic development in the region.
