摘要
锶是生物有机体内必需的微量元素之一,具有改善骨代谢、增强骨质强度,预防龋齿、“三高”和心血管疾病,有益肝细胞的增殖和胆红素代谢等作用。富锶土壤作为新的优势地质资源,逐渐受到重视,多个地方推出富锶农产品。目前对土壤中锶的地球化学特征研究较少,也无土壤富锶含量标准,这些严重制约了富锶生态农业的发展。研究区在河南固始史河一带,分析归纳不同成因、不同类型土壤中锶的含量特征及空间的分布规律,研究土壤锶形态及与其他元素相关性,总结土壤中锶地球化学特征。并对土壤富锶含量进行探讨,推荐提出富锶土壤锶含量标准:表层土壤中Sr含量≥205 mg/kg。并以此标准对固始史河一带土壤富锶资源进行评价,圈定绿色无公害食品富锶耕地236.3 km2,优选建立富锶特色农业示范区,助力地方美丽乡村建设。
Strontium is one of the essential trace elements in biological organism.It can improve bone metabolism,enhance bone strength,prevent dental caries,"three highs"and cardiovascular diseases,and benefit liver cell proliferation and bilirubin metabolism.As a new advantageous geological resource,strontium-rich soil has gradually been paid attention,and strontium-rich agricultural products have been pushed out in many places.In this study,in the Shihe River area of Gushi County in Henan,the strontium content characteristics and spatial distribution regularity in soils of different origins and types are analyzed and summarized.The state of strontium in soil and its correlation with other elements are discussed,and the geochemical feature of strontium in soil is summarized.The content of strontium in soil is explored,and the standard for strontium content in strontium-rich soil is recommended to propose as follows.The content of Sr in the surface soil is≥205 mg/kg.Based on this standard,the strontium-rich soil resources in the Shihe River area of Gushi County are evaluated,and strontium-rich arable land for green and pollution-free food is delineated out of 236.3 km^(2),and a strontium-rich characteristic agricultural demonstration area is preferably established to help the construction of beautiful local villages.
