Selenium-containing trace element corn leaf fertilizer and cultivation technique thereof for selenium-rich corn

Abstract

The invention discloses a selenium-containing trace element corn leaf fertilizer and a cultivation technique thereof for selenium-rich corn. The selenium-containing trace element corn leaf fertilizer comprises the following raw materials in percentage by mass: 24-26% of chelate zinc, 3.5-4% of ammonium molybdate tetrahydrate, 24-26% of chelate iron, 12-13% of borax, 8.5-9% of sodium selenite and 24-26% of monopotassium phosphate. The cultivation technique comprises the following steps: preparing before seeding, selecting good seeds, seeding, densely planting reasonably, preventing diseases and removing insects, weeding, dressing the fertilizer, performing water-saving irrigation, and harvesting and storing. By adopting the selenium-containing trace element corn leaf fertilizer, the yield of corn is greatly increased, the content of the selenium element in corn is increased, the nutrition of corn self is maintained, and the content of the selenium element needed by human bodies can be met, therefore, the immunity is improved, and cancer can be prevented. As the fertilizer is completely absorbed by the crop, the cultivation technique is relatively safe and reliable.
