Abstract：Selenium（Se）isanessentialtraceelementforthehumanbodyandmustbeacquiredexternallythroughthediet. Thus，developingselenium-enriched functional crops has becomeakeystrategyfor selenium supplementation.In this studyFengtougingerwasusedasthetestmaterial.Afieldexperiment wasconductedinvolving foliarsprayingoforganic selenium and nano-selenium at concentrations ranging from 120 to 200mg⋅L-1 ，with spraying clear water as the control （CK）.The effects of different seleniumsources on ginger growth，quality，and seleniumaccumulation were analyzed.The resultsindicated that foliarapplicationof 120mg⋅L-1 nano-selenium resulted in a rhizome fresh mass of 1180g per ginger plant，which was significantly 76.12% higher than that of the CK.In contrast，spraying 200mg⋅L-1 organic selenium increased ginger yield by 28.36% .For the treatment with 200mg⋅L-1 nano-selenium，the soluble sugar content significantly increased O.16 percent points than that of CK，whereas the soluble protein content decreased by 0.63% . Although the 160mg⋅L-1 organic selenium treatment inhibited protein synthesis，the organic selenium content in ginger rhizomes reached 0.225mg⋅kg-1 ，a significant increase of 114.29% compared with CK.Nano-selenium treatments significantly reduced soil pH to the range of5.09-5.32andactivated soil nitrogen，phosphorus，and potassum（with available potassium content decreasing significantly by 47.69% .Incontrast，organic selenium exhibited a bidirectional regulatory effect on soil pH.Considering yield，quality，and soil environmental impacts comprehensively， 160mg⋅L-1 organic seleniumwas identified as the optimal concentration for selenium enrichment（achieving the peak organic seleniumcontent inginger）. However， 200mg⋅L-1 nano-selenium was more suitable for functional ginger production，as it not only increased yield by 25.37% butalso enhanced selenium fortificationand soil nutrient activation.
