连城县文亨镇土壤及红衣花生籽仁硒含量研究

Study on the Contents of Selenium in Soil and Red-membrane Peanut Seed Kernel in Wenheng Town of Liancheng County

摘要: 取样测定连城县文亨镇土壤及红衣花生籽仁硒含量，结果表明：连城县文亨镇各村花生种植基地花生表层土壤硒含量0.172~0.800 mg·kg^-1，平均值为0.368 mg·kg^-1，以福坑村的花生种植基地土壤平均硒含量最高，属富硒土壤；各村种植的红衣花生籽仁全硒含量为8.0~36 μg·kg^-1，平均值22 μg·kg^-1，以福坑村的花生籽仁硒含量最高；土壤硒含量与花生籽仁硒含量呈显著的正相关关系。

Abstract: The contents of selenium in soil and red-membrane peanut seed kernel in Wenheng Town of Liancheng County were sampled and determined. The results showed that the content of selenium in the surface soil of peanut-planting base of each village was 0.172-0.800 mg·kg^-1 with the average value of 0.368 mg·kg^-1. The average content of selenium in the soil of the peanut planting base in Fukeng Village was the highest, and it was a selenium-richened soil. The total content of selenium of the red-membrane peanuts seed kernel cultivated in these villages was 8.0-36.0 μg·kg^-1 with an average value of 22 μg·kg^-1, and the content of selenium in the peanut seed kernel was the highest in Fukeng Village. The content of selenium in soil was positively correlated with that in peanut.
