【摘要】 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。更多还原

【Abstract】 Saline soils of Liaohe river delta were formed based on parent materials of delta deposit and coastal deposit which the main type were saline soils of tidal flat, etc. It formed pattern on utilization of water and land resources which use planting rice as the main under the condition of develop the farmland, dig waterways, guiding the freshwater and vent salt water. At the same time it built comprehensive technology system which were longitudinally arrange field engineering and subsurface drain pipe. It is the major direction for regional production economic progress to develop solonchak economy and strengthen prevention of the secondary salinification in the new stage of history and resources.更多还原
