【摘要】 微量元素分析研究表明,琼北地区土壤大部分微量元素背景值与世界及中国土壤较为相似;区内土壤环境质量好,达到国家一级标准,是热带优质作物的理想生产基地;相对来说,母质为基性火山岩的土壤农业地球化学质量最好,水稻土壤次之,母质为花岗岩和砂页岩土壤较好,母质为浅海沉积物的土壤较差。更多还原

【Abstract】 The trace element geochemical characteristics of the soils in northeastern Hainan was proceeded in this paper. The background values of the trace elements of the soils are similar to the soils in the world and in China.The result shows that the environmental quality of the soils in northeastern Hainan is good enough to get the first agricultural standard of China, and so to be the ideal farming base for growing high grade tropic agronomic crops. By comparing study, it was found that soils based on the basic volcanic were the highest agro-geochemical quality, and in turn the paddy fields; soils from the agricultural rocks and sands were a little better than that from the neritic sediments.更多还原
