| 中文摘要: |
| 汝州市大部分地区属于富硒土壤区，为促进全市传统农业产业的提升发展，合理开发利用优质土地资源，打造富硒农产品品牌，对汝州市开展1∶50 000富硒土壤详细调查。将1 148件表层土壤及38件深层土壤样品的硒含量测定数据进行统计分析，探讨汝州市土壤中硒元素分布情况及控制因素。结果表明：汝州市表层土壤硒含量范围为0.026 mg/kg~3.030 mg/kg，平均值为0.232 mg/kg;深层土壤硒含量范围为0.054 mg/kg~0.632 mg/kg，平均值为0.214 mg/kg，高于河南省硒含量平均值0.190 mg/kg；从空间分布看，汝州市土壤硒元素的空间分布整体呈中部、西北部及南部地区含量高，东部、东北部和西南边缘区域含量低的特点。该地区不同土壤类型中硒元素含量明显不同，水稻土的平均硒含量最高，达到0.399 mg/kg；不同土地利用类型的土壤硒含量存在明显差异，旱地的平均硒含量最高，为0.243 mg/kg；土壤硒含量与pH呈负相关关系。 |
| 英文摘要: |
| Most of Ruzhou City belongs to a selenium-rich soil area. To promote the upgrading and development of the city's traditional agricultural industry, rationally develop and utilize high-quality land resources, and create a brand of selenium-rich agricultural products, a detailed investigation of 1:50,000 selenium-rich soil in Ruzhou City is carried out. The selenium content measurement data of 1148 surface soil and 38 deep soil samples are statistically analyzed to explore the distribution of selenium in the soil of Ruzhou City and the influencing factors. The results show that the selenium content of surface soil in Ruzhou City ranges from 0.026 mg/kg to 3.030 mg/kg, with an average value of 0.232 mg/kg, and the selenium content of deep soil ranges from 0.054 mg/kg to 0.632 mg/kg, with an average value of 0.214 mg/kg, which is higher than that of the average value of selenium content in Henan Province (0.190 mg/kg); the spatial distribution of soil selenium in Ruzhou City is characterized by high content in the central, northwestern, and southern areas, and low content in the eastern, northeastern, and southwestern edges. The selenium content of different soil types in the region is obviously different, the average selenium content of rice soil is the highest, reaching 0.399 mg/kg; the selenium content of soils of different land-use types is obviously different, and the average selenium content of dryland is the highest (0.243 mg/kg); the Se content of soils is negatively correlated with pH values. |
