The selenium content of soils from five orchard areas in Kaiyang couty was determined by hydride generation-atomic fluorescence spec-trometry(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 back-ground concentration values(0.29 mg/kg)of China and that(0.369 mg/kg)of Guizhou.According to classification standard of national seleni-um 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.
