Embodiment 1

[0027] The method of planting selenium-enriched corn is to apply selenium-enriched organic fertilizer and selenium-enriched nutrient solution at different stages of corn growth, and apply 30-50Kg of selenium-enriched organic fertilizer with selenium content ≥ 50mg / Kg per mu when leveling the land before corn sowing ; 7--10 days during the corn filling period, spray 80--100ppm of selenium-enriched nutrient solution on the leaf surface of corn per acre, and obtain selenium-enriched corn after the corn is mature; the selenium content of the selenium-enriched corn is 0.15- —0.30mg / Kg, organic selenium content ≥ 70%.

[0028] The preparation method of the organic selenium-enriched fertilizer described in the above-mentioned embodiment is, take selenium ore rock, selenium-enriched agricultural crop waste, carbon source, nitrogen source, calcium hydroxide, microbial bacterial agent and micro-fertilizer as raw material, described raw material weight The ratio of parts is 50-100 parts ...

Abstract

The invention provides a method for planting selenium-rich corns and belongs to the technical field of production of selenium-rich agricultural products, wherein the method is low in cost and the corns are rich in organic selenium. According to the method provided by the invention, a selenium-rich organic fertilizer and a selenium-rich nutrient solution are applied to the corns at different growth stages; and the method has key points of: when leveling land before planting the corns, applying 30-50 kg of the selenium-rich organic fertilizer per mu, wherein the selenium content of the selenium-rich organic fertilizer is greater than or equal to 50 mg/kg; and after the grain-filling period of the corns for 7-10 days, spraying 80-100 ppm of the selenium-rich nutrient solution on the corn leaves per mu, and after the corns are ripe, obtaining the selenium-rich corns. The planting method is simple and low in production cost, and the planted selenium-rich corns are high in organic selenium content.

Description

technical field [0001] The invention belongs to the technical field of production of selenium-enriched agricultural products, and in particular relates to a method for planting selenium-enriched corn. Background technique [0002] Selenium is the fire of life, the fifth anti-cancer, the foundation of health, and can effectively prevent and treat more than 40 kinds of human diseases. More than 80% of the countries and regions in the world are low in selenium or deficient in selenium, and 72% of the regions in my country are deficient in selenium. Using plants to realize the transformation of inorganic selenium into organic selenium and increasing the selenium content in food is fundamental to improving the selenium nutrition of humans and animals Measures, plants have a strong ability to enrich selenium, and can actively absorb selenium in the environment. During the plant transformation process, it becomes natural organic selenium through the action of many amino acids in the...
