In the production method of selenium-enriched Perilla frutescens seeds, a selenium-enriched foliar fertilizer is sprayed to leaves in a full-blossom period of the Perilla frutescens seeds, and inorganic selenium is converted into organic selenium to exist in the Perillafrutescens seeds. In the present invention, a critical technical problem of selenium enrichment of Perilla frutescens seed products is solved by adopting a method for spraying a formulated selenium micro-fertilizer to leaves； and the content of a-linolenic acid in Perillafrutescens is stabilized, so that selenium content in the Perilla frutescens seeds is increased generally from about 0.05 mg/kg to 3.27 mg/kg. Compared with the prior art, the present invention increases the selenium content by 65 times, and increases the seed yield by 5.49% than the prior art.Drawings of Description Preparation of the selenium-enriched foliar fertilizer: 3000 ml of selenium fertilizer, 200 ml of S101 humic acid foliar fertilizer, 50 g of monopotassium phosphate and 6 ml of surface dispersant Application period: surveying a target land； and considering 3-5 days after the full-blossom 02 period of the Perilla frutescens plants as an optimum application period S103 Spray method: preparing various raw materials of the selenium-enriched foliar fertilizer according to a ratio； performing leaf spray on the Perilla frutescens plants in the full-blossom period before 11:00 a. m and after 15:00 p. m on a sunny and windless day； during use, firstly dissolving the recommended amount of 667m2 of 50 g monopotassium phosphate with 1000 ml of water, and mixing with 30 kg of water； adding 3000 ml of the selenium fertilizer, 200 ml of the humic acid foliar fertilizer and 6 ml of the surfac
