山西省由于受内陆地区地势、气候、地形等因素的影响,土地盐碱化面积较大。根据2008年全省组织的盐碱地调查,全省共有各类盐碱地410.35万亩,其中,苏打型盐碱地198.8万亩,占全省盐碱地总面积的48.4%。近8年来,省土肥站持续开展了苏打型盐碱地改良和治理,基本摸清了苏打型盐碱地的特征,并总结出了切实可行的综合改良技术模式。1山西苏打型盐碱地特征1.1面积大且分布较集中苏打型盐碱地主要分
Due to the terrain, climate and topography in the hinterland, Shanxi Province has a large area of salinization. According to the investigation of the saline-alkali soil organized by the province in 2008, there are 4,103,500 mu of various kinds of saline-alkali land in the whole province, of which 198,800 mu are soda-type saline-alkali land, accounting for 48.4% of the total area of saline-alkali land in the whole province. In the past eight years, the provincial Soil & Fertilizer Station has carried out the improvement and treatment of soda-based saline-alkali soils and has basically ascertained the characteristics of soda-saline-alkali land and summarized the practical and comprehensive technological improvement models. 1 Characteristics of Shanxi soda ash salinization area 1.1 Large area and concentrated distribution Soda ash main
