Macroelement soluble fertilizer and preparation method thereof

Abstract

The invention discloses a macroelement soluble fertilizer and a preparation method thereof. The macroelement soluble fertilizer disclosed herein comprises 50-60 weight parts of dipotassium hydrogen phosphate, 5-7 weight parts of phosphoric acid, 33-38 weight parts of urea, 0.8-1.2 weight parts of zinc chloride, 2-4 weight parts of instant boron, 2-3 weight parts of disodium ethylene diamine tetraacetate, 1-2 weight parts of animal hair and feather, 8-12 weight parts of ammonium nitrate, 2-4 weight parts of stemona powder, 3-5 weight parts of vinasse, 5-7 weight parts of eucalyptus robusta leaf, 7-9 weight parts of sugarcane leaf, 2-5 weight parts of modified wood ash, 4-6 weight parts of trace element fertilizer, and 60-70 weight parts of water. According to the invention, amino acid is generated by acid hydrolysis and the like, then chelation is carried out on medium and trace elements, and the chelated structure is added to carboxymethyl cellulose, thus effective utilization of the medium and trace elements is benefited, and ineffective release of the medium and trace elements is benefited is reduced; the content of the nutrients included in the fertilizer is high, the production process is simple, the processes of evaporation, crystallization and drying are reduced, the produced dipotassium hydrogen phosphate solution can be directly used for preparing the liquid soluble fertilizer, the ph is 6.0-8.0, and there is no corrosion to pouring pipelines and nozzles.

Description

technical field [0001] The invention belongs to the field of water-soluble fertilizer production, and in particular relates to a large-element water-soluble fertilizer and a preparation method thereof. Background technique [0002] Water-soluble fertilizers with a large number of elements can be made from raw materials such as dipotassium hydrogen phosphate, phosphoric acid, urea, ammonium nitrate, and trace element fertilizers, and scientifically researched and formulated with additives such as chelating agents, solubilizers, and wetting agents. At present, my country accounts for 9% of the world's arable land, uses 6% of the world's fresh water resources, produces 26% of the world's agricultural products, and feeds 21% of the world's total population, which is already a miracle. But looking forward to the future, due to the shortage of fresh water and arable land in our country, the huge population and the rapid increase, the pressure to solve the living problems of our pe...
