【Abstract】 In the present paper, a new method of the extracted Se from the acid soil by 0.1 M KH2PO4has been proposed. The results of analysis of soils and plants has proved that the KH2PO4extracted Se may reflect the situation of Se supplied by soil for plant. The rye seeding test further has shown that the KH2PO4extractcd available Se for plant.更多还原
