摘　　要：文章采用双道氢化物发生-原子荧光光度计初步探索开阳县三个乡5个果园土壤中的硒含量。土壤样品中硒平均质量分数为0.53 mg/kg,高于中国土壤硒的背景值(0.29 mg/kg)和贵州省土壤硒平均质量分数(0.369 mg/kg)。依据中国硒元素生态景观界限值的等级划分标准,研究区土壤有丰富的硒资源,值得深入研究,以促进当地富硒农产品的开发。The selenium content of soils from five orchard areas in Kaiyang couty was determined by hydride generation-atomic fluorescence spectrometry(HG-AFS).The result shows that the average content of selenium in target area is 0.53 mg/kg,which is much higher than the background concentration values(0.29 mg/kg)of China and that(0.369 mg/kg)of Guizhou.According to classification standard of national selenium element ecology landscape threshold value,selenium content of sampling areas is very high.The selenium content of orchard areas in Kaiyang couty is worth further research in order to develop selenium-enriched fruit in the local area.
