Novel selenium-enriched rice and production method thereof

The invention discloses novel selenium-enriched rice and a production method thereof. The selenium content of the rice is 190mu.g/kg-210mu.g/kg; in each Mu of rice paddy, 400ml-500ml of a selenium-enriched organic solution is taken and dissolved into 30kg-35kg of water; after the solution and the water are uniformly mixed, the selenium-enriched organic solution is sprayed on rice leaves for one time at a 20%-35% tassel period of the rice; 30kg-50kg of a boric acid with the concentration of 0.3%-0.5% in each Mu for one time at a full heading period of the rice; and after the rice is ripen, the rice is harvested. By adopting a cultivation and planting technology of the selenium-enriched rice, provided by the invention, the content of organic selenium in the rice is effectively improved; a sprayed selenium-enriched biological organic fertilizer is completely converted into organic selenium in the rice; and other special cultivation management measures are not needed in a rice cultivation process, so that the cos
