The invention discloses a planting method of selenium-enriched organic rice. The method comprises the steps of 1, field management, wherein a heavy metal adsorbing material with a thickness of 5-10 cm is laid after rice field soil is deeply plowed by 55-70 cm, then soil refilling is carried out, next, underground water is poured to soak the rice field for 20-30 days, again, the soil is exposed under the sun for 3-5 days after the water is drained, the heavy metal adsorbing material is taken out, and finally, an inorganic fertilizer with a thickness of 2-4 cm is buried at the 10-15 cm position of the soil; 2, transplanting management; 3, fertilization management, wherein firstly an active material is sprayed 1-3 hours before a selenium-rich leaf force fertilizer is sprayed, and the spraying quantity of the active material is 10-20 kg / mu. The selenium-rich organic rice planted through the planting method is fine and long in granule, crystal, transparent, soft and non-stick, the content of organic selenium is high, the incidence of diseases and insect pests is low, the content of heavy metal is low, and the selenium-rich organic rice has market competitiveness.
