中文摘要:
      通过对石阡县耕地质量地球化学评价研究显示,土壤中硒元素总体平均含量为038 mg/kg,硒含量变化范围为007835 mg/kg;石阡县898 300亩耕地中共圈定富硒区243 410亩,清洁富硒区240 40129亩,主要集中分布在本庄、龙塘、龙井、青阳、石固、聚凤、河坝等七个乡镇,清洁富硒区主要成土母岩为二叠系吴家坪组灰岩、煤炭质页岩和寒武系牛蹄塘组碳质页岩土壤中;共划分了龙塘-龙井富硒茶叶及茶山观光园区、山口坳-永和富硒茶叶、富硒水果优先开发区、马屯-聚凤富硒水稻、蔬菜、茶叶优先开发区、朝阳-新丰富硒水果种植区四个富硒优先开发区。
英文摘要:
      According to the geochemical evaluation of cultivated land quality in shiqian county, the overall average content of selenium in the soil is 0.38 mg/kg, and the variation range of selenium content is 007835 mg/kg. According to the evaluation standard of soil selenium-rich soil, shiqian county has defined a total of 243 410 mu of selenium-rich areas and 240 401.29 mu of clean selenium-rich areas. Mainly concentrated in this zhuang, longtang, longjing, qingyang, shigu, jufeng, heba and other seven towns, The main parent rocks in the clean selenium-rich area are the limestone of the wujiaping formation of Permian, the coal shale and the carbon shale soil of the niuitang formation of Cambrian. According to the traffic location, soil environment, fertility, selenium - rich intensity and other parameters four se-rich priority development zones are divided into longtang-longjing se-rich tea and tea mountain sightseeing park, shankou ao-yonghe se-rich tea, se-rich fruit priority development zone, matun-jufeng se-rich rice, vegetables, tea priority development zone, and chaoyang new-rich se-rich fruit planting zone.
