Problems solved by technology

[0002] At present, the medium-element calcium water-soluble fertilizers on the market are generally unstable in chemical properties. The primary raw materials commonly used in medium-element water-soluble fertilizers are calcium ammonium nitrate, calcium nitrate, or calcium formate, because only these raw materials have sufficient calcium content. High, it is easy to meet the current NY2266-2012 standard, but all of the above calcium is in an ion state after being dissolved in water, and it is easy to form calcium dihydrogen phosphate precipitation with fertilizers containing phosphorus elements, resulting in blockage of fertilization pipes and reduced fertilizer efficiency , Soil compaction, eventually causing crops to be deficient in calcium and phosphorus

Abstract

The invention discloses a preparation method of a powder chelated calcium medium element water-soluble fertilizer. The preparation method comprises the following steps of: step 1, preparing raw materials of disodium ethylene diamine tetraacetate, calcium carbonate and deionized water, and preparing devices of a heating reaction kettle, a measuring cylinder and a beaker; step 2, heating biochemical potassium fulvate according to the weight to 60-70 DEG C, uniformly mixing dimethyl pyrazole phosphate, chitosan oligosaccharide and 4-amino-1, triazole, adding the mixture into the biochemical potassium fulvate, performing uniform stirring, preserving heat for 35-45 minutes at the temperature of 60-70 DEG C, cooling to room temperature, and transferring a product into a stirring kettle, and finally adding a water-soluble nitrogen fertilizer, a water-soluble phosphate fertilizer and a water-soluble potash fertilizer into the stirring kettle according to the weight. According to the preparation method of the powder chelated calcium medium element water-soluble fertilizer, the disodium ethylene diamine tetraacetate, calcium carbonate and deionized water are put into the reaction kettle ,chemical reaction is carried out to generate a large amount of foams, and disodium calcium ethylene diamine tetraacetate monohydrate is generated after the foams disappear.
