In order to cooperate with the 1:50000 geochemical survey of land quality in six counties of Ganzhou, the authors selected Ruijin and Shicheng survey areas.Surface soils, 70 sets of white lotus and root soil were collected in the whole area.Twenty three elements in lotus and root soil, including 10 trace elements beneficial to human health, were determined.The content, correlation and geological background of selenium and other beneficial elements in the fruit and root soil of white lotus were analyzed.The survey results are as follows:①The values of Cd, Pb, Cr, Hg and As in white lotus of Shicheng County are lower than the limit value in GB2762-2017 standard.Except for 36% Pb exceeding the standard, other heavy metals in white lotus in Ruijin do not exceed the standard.The content of five heavy metals in the corresponding root soil is lower than the screening value, and the surface soil of Ruijin Shicheng survey areas is green and safe.Two green selenium rich bases were delineated, with an area of 92 km2 in Ruijin and 5.6 km2 in Shicheng.②White lotus produced in Ruijin-Shicheng survey areas is rich in selenium, which is more than 80%, and is rich in 10 kinds of trace elements needed by human body, which will provide technical support for the development of selenium rich white lotus.③Selenium rich white lotus was found in non-selenium rich soil, which may be related to the biological availability of selenium in soil and its own characteristics.
