Abstract: Through the agricultural geochemical survey of Bashang area of Shangyi County,we obtained the initial data,including 27 indicators of soils,12 indicators of irrigation groundwater,and 12 indicators of oat seeds and their root soils.Comparing the relationship of soil and irrigation groundwater indicators between preponderant area and the average,we concluded that in oat superiority area,Corg、N、P were higher,Si、Na were relatively higher,Mg、Cl、S、 Ca were lower,which indicated the sandy loam soil environment.The quality of irrigation water was better because of the higher content of Sr and Se.By creating site geological environment model and summarizing recommendations in oat planning,our study provided a theoretical basis for agricultural production and ecological environment planning that suit local circumstances.
