Fujian Province is an important producing area of bayberry in China. Fugong bayberry, known overseas for its unique quality, is a high quality agricultural product. The main production area of bayberry in Longhai was selected for this study. Rocks, soils and fruits were sampled from this area, and the values of their main components and beneficial-nutritional as well as harmful elements were determined. The authors also measured the available values of some nutritional elements. Some conclusions have been reached:(1) The content of beneficial-nutritional elements is higher in Fugong Town than that in Dongsi Town. On the contrary, the content of harmful elements in the Dongsi Town is relatively higher than that in Fugong Town; (2) there is a certain correlation for the composition of elements between rocks, soils and fruits, reflecting the impact of geological setting on geochemistry; (3) the available values of P, Mn, Cu, and Zn have significantly positive correlation with their total content; (4) the content of Se in rocks and soils in the study area is obviously higher than the national average level, and the rate of Se-enriched is up to 74.3% for 35 bayberry fruits; (5) the Transfer Factor (TF) of beneficial-nutritional elements is significantly higher than that of harmful elements, indicating bayberry's active selective uptake of beneficial-nutritional elements and inhabitation of the intake of harmful elements.
