Abstract

The invention belongs to the technical field of plant nutrition, relates to a method for producing selenium-enriched SOD agricultural products, and discloses enzyme amino acid nano-selenium micro-fertilizer for degrading grain pesticide residues. In 50,000 parts, the enzyme amino acid nano-selenium micro-fertilizer is prepared from the following raw materials in parts by weight: selenium-containing trace elements: 15 to 40 parts of sodium selenosulfate, 500 to 1000 parts of amino acid trace element water-soluble fertilizer, 140 to 230 parts of an electrolyte PH buffer, 50 to 100 parts of aminoacid raw powder, 230 to 360 parts of an organic material base, 250 to 375 parts of a selenium-enriched SOD nutrient material, 255 to 510 parts of probiotics and the balance of pure water. The prepared product contains 0.130 g / part to 0.350 mg / g of selenium, 450 to 1000 U / g of SOD, 15.5 to 31.0 mg / g of amino acids, 3.0 to 6.0 mg / g of copper, zinc, manganese, iron, boron and molybdenum trace elements, nano-selenium at a particle size of 20 to 40 nm and active bacteria in a total quantity more than or equal to 0.1 billion / g. The invention relates to water-soluble compound fertilizer for producing the enzyme amino acid nano-selenium micro-fertilizer of polyfunctional agricultural products without pesticides and hormones.

Description

technical field [0001] The invention belongs to the technical field of plant nutrition, and relates to the production and application of amino acids, nano-selenium, trace elements and active enzymes, and a method for producing selenium-enriched SOD agricultural products. Background technique [0002] Selenium is an essential trace element in human and animal life. It has many important functions in ensuring human health, including immune regulation, anti-fatigue, anti-oxidation, and anti-aging. Low immunity and antioxidant function are important causes of many chronic diseases (hypertension, coronary heart disease, diabetes, cancer, etc.). Scientific supplementation of selenium is beneficial to prevent the occurrence of the above-mentioned diseases, and can also help the body resist acute infectious diseases, such as influenza. To play these roles of selenium, the "Reference Intake of Dietary Nutrients for Chinese Residents" points out that the intake of selenium should be ...
