Methods: Pot and hydroponic experiments were conducted at the wheat seedling stage. The Se concentrations in shoots and roots of wheat and soil were analyzed by HG-AFS-8220. Selenium content in the soil was divided into different fractions and species. Results: The application of 150mg∙kg−1S reduced Se concentrations in wheat shoots and roots significantly, declining 47% and 45%, respectively. Sulphur treatment changed soil pH (maximum decrease of 0.52 units) and organic matter content (maximum increase of 0.96g∙kg−1) significantly, thereby reduced the soluble Se concentration, increased the iron (Fe)/manganese (Mn) oxide-bound Se concentration. Sulphur treatment also reduced the concentration of Se6+ in the exchangeable fraction. Conclusions: The application of S fertiliser promoted soluble Se transformation to Fe-Mn oxide-bound Se, organic matter-bound Se and residual Se by lowering soil pH and increasing organic matter content, and inhibited the transformation of Se4+ to Se6+ in the exchangeable fraction, hence reducing wheat uptake of Se in high-Se areas.
