Abstract

The invention discloses a nano-selenium-containing amino acid foliar fertilizer and a preparation method thereof. The nano-selenium-containing amino acid foliar fertilizer is prepared from such raw materials as molasses, animal hair, selenium dioxide, sulfuric acid, copper sulfate, manganese sulfate, zinc oxide, ferrous sulfate, ammonium carbonate, ammonium molybdate, urea, potassium chloride, boric acid, fulvic acid, a surfactant, ethylene glycol, sodium carbonate, quick lime or calcium hydroxide, phosphoric acid and water. The preparation comprises the steps of reducing selenium dioxide by use of the molasses to obtain nano-selenium, hydrolyzing the animal hair into an amino acid solution, and then performing the reactions of neutralization, complexing, emulsification and the like to obtain the nano-selenium-containing amino acid foliar fertilizer. According to the nano-selenium-containing amino acid foliar fertilizer, the problem of transforming inorganic selenium into nano-selenium and the problem of recycling waste both are solved; the fertilizer is capable of improving the water retention and drought resisting capability of plants and increasing the content of the organic selenium element content in crops; the preparation method of the fertilizer is mild in reaction conditions, simple in process, relatively low in production cost and prone to industrial production, and has excellent economic benefit, social benefit and ecologic benefit.

Description

technical field [0001] The invention belongs to the technical field of harmless treatment of agricultural and sideline products and resource reuse, and relates to a method for producing fertilizers from urban and rural wastes such as molasses and animal hair, in particular to an amino acid foliar fertilizer containing nano-selenium and a preparation method thereof. Background technique [0002] Amino acids are essential nutrients for plant growth. Amino acids are prepared by hydrolyzing proteins, and at the same time adding trace elements and plant growth regulators to prepare amino acid foliar fertilizers can promote plants to better absorb nutrients through leaves. Chinese patent CN101781151A discloses a water-soluble fertilizer with trace elements in amino acid chelation and its preparation method. The raw material components of the invention are: 45-55 parts of compound amino acid aqueous solution, 39-43 parts of medium-trace element compounds, and 8.5- 10.8 parts, 1.2-2...
