Abstract

The invention discloses a preparation method of amino acid chelated selenium. The amino acid chelated selenium foliar fertilizer capable of being efficiently absorbed by crops is obtained by performing ultrafine powder treatment on a selenium raw material, a potassium raw material and a nitrogen raw material after mineral purification, performing a chelation reaction by using a compound amino acidsolution obtained through concentrating after biological fermentation and extraction of glutamic acid, adding a suspending agent, a penetrating agent and an antioxidant and carrying out emulsification treatment. The compound amino acid chelated selenium foliar fertilizer produced by the method disclosed by the invention is stable in physicochemical properties, free of ion antagonism, uniform in foliar adhesion, high in absorption and utilization rate, free of toxicity and harm to crops, capable of being directly absorbed through leaves, and relatively rapid in transformation in plants. The invention further provides an application method of the compound amino acid chelated selenium foliar fertilizer. According to scientific calculation, crops can reach a selenium enrichment level requiredby national standards, scientific selenium enrichment and index control can be achieved, safety and effectiveness are realized, and the development cost of selenium-enriched crops is reduced.

Description

technical field [0001] The invention belongs to the technical field of selenium-containing functional fertilizers, and in particular relates to a preparation and application method of an amino acid chelated selenium foliar fertilizer. Background technique [0002] At present, the ways to supplement selenium include drugs, selenium nutrition enhancers, and selenium-enriched foods, among which selenium-enriched foods are the most direct and convenient. The standards for the scientific content of selenium in the human body include the minimum selenium requirement (17 μg / d), the physiological selenium requirement (40 μg / d), the dietary selenium supply (50-250 μg / d), and the highest safe dietary selenium intake (400 μg / d). d), and the human selenium poisoning threshold (800μg / d), approved by the World Food and Agriculture Organization, the World Health Organization, and the International Atomic Energy Agency. The development of selenium-enriched agricultural products will provid...
