摘要: 延津县风沙土系黄河故道主流沉沙经风力搬运后发育而成,因而形成的各类土壤均具有质地轻粗,有机质贫乏,保肥能力弱和富钾缺磷等特点。所以,在改良利用上应该积极营造防护林,引黄淤灌,创造细土层,改造粗骨性,大力施用有机肥,因地制宜,综合发展,并以广开肥源,种植绿肥,培育和提高土壤肥力为重点。

关键词: 风沙土, 沙地改良, 土地利用

Abstract: The wind-sand soil in Yanjin county is old Yellow river's sediments experincing transportation by wind and development.So the formed soil types have the characteristics of coarse texture,poor organic matter,low capability of maintaining fertility and soil moisture,rich potassium and poor phosphorus.Therefore,in consideration of the amelioration and utilization of the sandy land,it is key to establish shelter belt,form fine earth horizon,ameliorate coarse texture,expand fertilizer source,plant green manure crop and increase soil fertility.

Key words: wind-sand soil, sandy land amelioration, land use
