Problems solved by technology

[0003] The technical problem solved by the present invention is to provide an ecological selenium-enriched fertilizer and its application in corn planting, so as to solve the problem that the selenium content of corn seeds produced by traditional methods is insufficient and cannot meet the human body's demand for selenium. The program optimizes the corn planting process, which is beneficial to transform the inorganic selenium in the soil and fertilizer into organic selenium that is beneficial to human body absorption, and then obtains a green, safe and reliable corn product

Abstract

The invention discloses an ecological selenium-rich fertilizer. Every 100 parts by weight of the ecological selenium-rich fertilizer comprises the following raw materials: 15-20 parts of astragalus sinicus, 6-8 parts of calcium magnesium phosphate powder, 6-8 parts of calcium superphosphate powder, 3-5 parts of medical stone powder, 3-5 parts of zeolite powder, 3-5 parts of potassium feldspar powder, 6-8 parts of tung cake powder, 6-8 parts of rapeseed cake powder, 3-4 parts of potassium sulfate powder, 0.6-1.0 part of ferrous sulfate powder, 1-1.5 parts of zinc sulfate powder, 0.6-1.0 part of magnesium sulfate powder, 0.6-1.0 part of manganese sulfate powder, 1.5-2.0 parts of sodium metasilicate powder, 0.15-0.2 part of sodium selenate powder, 0.5-1.0 part of copper sulfate powder, 1.5-2.0 parts of borax powder, 0.35-0.4 part of ammonium molybdate powder, 1.5-2.0 parts of rare earth chloride powder, 1.5-2.0 parts of a soil phosphorus activator and the balance of water. After the ecological selenium-rich fertilizer is applied to corn planting, the content of organic selenium in obtained corn ranges from 0.15 mg/kg to 0.23 mg/kg, the national food nutrition enhancer use standard is met, and better economic value is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to an ecological selenium-enriched fertilizer and its application in corn planting. Background technique [0002] Selenium is an essential nutrient element for the human body. Selenium has anti-cancer effects. Selenium deficiency in the human body is prone to liver cancer, lung cancer, gastric cancer, esophageal cancer, kidney cancer, prostate cancer, bladder cancer, cervical cancer, leukemia, etc.; selenium has antioxidant effects. Selenium is the best anti-aging substance. If the human body lacks selenium, it will "no longer young", which will lead to premature aging; selenium can enhance human immunity. Selenium deficiency reduces the body's immunity; selenium can antagonize harmful heavy metals, and selenium deficiency can easily cause lead, arsenic, cadmium and other heavy metal poisoning symptoms; selenium can regulate the absorption and utilization of vitamin ...
