The invention discloses application of an exogenous selenium-molybdenum composition in relieving chromium stress of tobacco seedlings, and belongs to the technical field of agriculture. An indoor water culture experiment is carried out, and the influence of the selenium-molybdenum combination on biomass, chlorophyll content, antioxidant enzyme activity, rhizome ultrastructure, leaf tissue structure and subcellular distribution of Cr in tobacco seedlings under Cr stress is analyzed. The invention proves that the selenium-molybdenum composition can improve the growth condition of the tobacco under chromium stress, enhance the heavy metal stress resistance of the tobacco, and provide effective reference for exploring the safety production of the tobacco and other crops.
