The present invention belongs to the technical field of the tobacco production. The present invention provides a production method of Selenium-enriched tobacco. The method comprises the following steps that: (1) 20 to 40 days before the tobacco seedling is transplanted in the large field, the solution containing the selenium-ion with the concentration of 0.5 ppm to 5 ppm and the agricultural rare earth with the concentration of 0.001 percent to 0.02 percent is used for floating culture of the seedling, and the spacing interval for every time of the floating culture of the seedling is 8 to 12 days; (2) after the tobacco seedling is transplanted in the field, Selenium-enriched nutrient fluid containing the selenium iron with the concentration of 5ppm to 50ppm is sprayed on the leaves of the tobacco during the growth period; and the spraying quantity is 30 L to 50 L per six acres; (3) after the tobacco is matured, the tobacco can be harvested. Adopting the mineral element selenium as the micro fertilizer to cult
