Abstract: Literatures on selenium-enriched corn production were studied to provide scientific guidance, so as to improve the production efficiency. The results showed that, foliar spray fertilizer application of selenium fertilizer was the oriented manner. The effect of spraying in tasseling stage by sodium selenite was the best, the optimal spraying concentration was 40-70 mg/kg. 64.5% of the sample could increase the maize yield, the average increase was 8.5%; 35.5% of the sample had yield decrease, the average yield decrease was 14.0%. The medium value of total selenium in corn was 0.211 mg/kg. According to the local standards of the latest selenium-rich products of Shaanxi Province (DB61/T556-2012), only 11.5% of the selenium enriched corn could meet the standard of 0.15-0.30 mg/kg, 44.2% of the selenium-enriched corn exceeded the upper limit of the standard, which would cause risk in food safety. The results could give guidance to the production of selenium-enriched corn.
