明溪县土壤硒分布特征及富硒土地资源开发利用

Characteristics of Soil Selenium Distribution and Development and Utilization of Selenium-enriched Land Resources in Mingxi County

基于明溪县农业地质调查评价项目获得的土壤和农产品元素检测数据,本文分析了耕地土壤硒元素的分布特征。调查发现,水稻、淮山、百香果、猕猴桃、绿茶、鸡蛋和淡水鱼等农产品可食部位富硒。明溪县富硒耕地约有66.56 km^(2),划分为富硒土地Ⅰ类优先建设区和Ⅱ类重点建设区。在富硒土地资源开发利用过程中,要结合当地国土空间规划、农业产业发展规划等,实施资源保护性开发战略,同时关注富硒土地资源的安全利用。

Based on the soil and agricultural product element detection data obtained by the agricultural geological survey and evaluation project of Mingxi County,this paper analyzes the distribution characteristics of selenium in the cultivated soil.The survey finds that the edible parts of agricultural products such as Oryza sativa,Dioscorea opposita,Passiflora edulis,Actinidia chinensis,green tea,eggs and freshwater fish are rich in selenium.The selenium-enriched arable land in Mingxi County is about 66.56 km^(2),which is divided into ClassⅠpriority construction area and ClassⅡkey construction area for selenium-enriched land.In the process of development and utilization of selenium-enriched land resources,it is necessary to implement resource-protective development strategies in combination with local land and space planning,agricultural industry development plans,etc.,and at the same time pay attention to the safe use of selenium-enriched land resources.
