Zusammenfassung:	The invention relates to a selenium-enriched rice production method for controlling rice blast. Selenium is an essential trace element in a human body, and China is a selenium lacking country, which determines that more people lack selenium, in view of the importance of rice in diet in China, the production of selenium-enriched rice is an effective way of supplementing national selenium; in addition, a rice blooming stage coincides with the high-incidence season of rice blast to seriously affect the rice yield. Therefore, a selenium-enriched nutrient solution and a preparation for controlling the rice blast are prepared into a composite preparation before the rice blooming stage, and a necessary surfactant and the like are added to achieve rice selenium enrichment and control the rice blast at the same time.
