摘 要:由于地理位置、地形、地下水埋深等原因,黄河三角洲土壤盐渍化严重,可利用的土地属于盐碱耕地型中低产田,但作为我国重要的后备耕地资源,其改良利用具有重要的战略意义。目前,对于黄河三角洲盐渍土改良措施主要有暗管排盐、修筑台田、土壤肥力提升、覆盖抑盐、土壤改良剂、咸水及雨水高效利用、耐盐作物筛选及种植等技术,进一步开展水肥盐优化调控、植物耐盐机理及根际土壤耐盐微生物的筛选工作,从而为黄河三角洲盐碱耕地型中低产田改造及利用提供科学依据。The soil in the Yellow River Delta is seriously saliferous because of its geographic location , topography , groundwater buried depth, etc.The available land in this area belongs to saline -alkali-type medium-low-yielding farmland.As the impor-tant reserved cultivated land resources in China , the improvement and use of this type of land have important strategic significance . Now the techniques for the improvement of the saline -alkali soil in the Yellow River Delta include eliminating salt through under-ground pipes , building platform field , improving soil fertility , inhibiting salt by covering , applying soil conditioners , high -effi-ciently using saline water and rainwater , screening and planting salt -tolerant crops, etc.Further conducting the studies on the opti-mized regulation of water -fertilizer-salt, salt-tolerant mechanism of plants , and screening of salt -tolerant microorganisms in the rhizospheric soil is important , and can provide scientific basis for the improvement and use of saline -alkali-type medium-low-yielding farmland in the Yellow River Delta .
