摘要: 尚义县为国家级贫困县,为了从根本上脱贫致富,因地制宜地进行马铃薯生产及生态环境规划,河北省地矿局出资对尚义县坝上地区开展了农业生态地质环境调查。结果表明:马铃薯优势区土壤Si、K和Na含量相对偏高,Mg、Cl、B、Ca、Cu、As等元素含量偏低,为沙质风积沉积环境;灌溉水水质较好且富Sr,呈弱碱性。通过建立地质地球化学模型对马铃薯种植进行区划,区划结果能有效地提高耕地的产能,发挥土壤内在质量优势,指导土壤平衡施肥,同时为土地利用规划修编、农作物种植结构调整提供可借鉴依据。

Abstract: As a national-level poverty-stricken county, the Shangyi County, conducts agricultural production and ecological environment planning through suitable local circumstances in order to shake off poverty fundamentally. At the same time, the Hebei Geology and Mineral Bureau contributed capital to carry out a survey of agriculture eco-geological environment. The result of the survey demonstrated that: in potato superiority area, the element content of Si, K, Na was relatively higher, and the one of Mg, Cl, B, Ca, Cu, As was relatively lower, which reflected the eolian sand environment. The quality of irrigation water was better, and the water was abundant in Sr and presents alkalescence. Creating site geological environment model and summarizing recommendations in potato planning, could improve the plowland capacity effectively and develop the soil inner quality advantage. At the same time, it had conductive meaning for soil balanced fertilization. The result of area planning provides reference for revision on land utilization planning and crop planting structural adjustment.
