通过对尚义县坝上地区开展农业地球化学调查,获取了研究区土壤27项指标、灌溉水12项指标、莜麦子实及其根系土共计12项指标的原始数据。对比分析莜麦优势区土壤、灌溉水相关指标与全区平均值的含量关系发现:莜麦优势区土壤中有机碳(SOC)、N、P含量明显高于全区平均值,是优势区的主要标志,Si和Na含量相对较高,Mg、Cl、S、Ca等常量元素含量偏低,反映的是偏沙壤性土壤环境;灌溉水水质较好,同时富Sr和Se。通过建立地质地球化学模型进行莜麦种植区划,总结种植规划建议,为该县因地制宜地进行农业生产及生态环境规划提供技术支撑。
Through the investigation of agrogeochemistry in Bashang area of Shangyi County, the original data of 27 indicators of soils, 12 indicators of irrigation water, 12 indicators of total wheat and its root soil were obtained. The results showed that the content of soil organic carbon (SOC), N and P in the soil of the dominant area was higher than that of the whole area, which was the dominant area The major indicators are that Si and Na are relatively high while those of Mg, Cl, S and Ca are low, which reflect the partial loamy soil environment. The quality of irrigation water is good and both Sr and Se are rich. Through the establishment of geo-geochemical model for oats planting zoning, plan planting recommendations summarized for the county according to local conditions for agricultural production and ecological environment planning to provide technical support.
