2018年广西横县土壤数据

数据库以广西横县63件水稻根系土壤为对象，分析测试了金属元素Cd、Cr、Cu、Ni、Pb、Zn、Mn、Al、Mn，土壤理化性质pH、SOM、EC、粒度，对研究分析次生富集型农田重金属元素的生物有效性、土壤重金属富集成因、土壤-水稻系统重金属迁移和生态风险分区具有十分重要的意义。

This dataset is based on 63 rice rhizosphere soil samples collected from Heng County, Guangxi Zhuang Autonomous Region, China. A series of tests and analyses were conducted on the samples, covering heavy metal elements including Cd, Cr, Cu, Ni, Pb, Zn, Mn, Al and Mn, as well as soil physicochemical properties including pH, SOM, EC and particle size. This dataset holds significant academic value for investigating the bioavailability of secondary-enriched heavy metals in farmlands, the formation causes of soil heavy metal enrichment, the translocation of heavy metals in the soil-rice system, and the delineation of ecological risk zones.
