Abstract

The invention provides a granular water-soluble fertilizer. The granular water-soluble fertilizer comprises small-grain urea with a nitrogen content of 46%, potassium nitrate, monopotassium phosphate, potassium sulfate, 73% monoammonium phosphate, magnesium sulfate, boric acid, gibberellin, polyglutamic acid, EDTA-Zn, EDTA-Fe, EDTA-Mn, fruit green, calcium stearate, sodium dodecyl benzene sulfonate, zeolite powder, chitosan, fish skin extract, polyvinyl alcohol, magnesium sulfate, fucitol calcium and water-soluble silicone oil. The preparation method comprises the following steps: preparation of carp skin extract, primary mixing and refining, heating, secondary refining, granulation and coating. The granular water-soluble fertilizer disclosed by the invention is good in solubility in a use process, is not easy to agglomerate, and is remarkable in yield increasing and quality improving effects compared with conventional fertilization, and an average yield increasing rate is 12.7%.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a granular water-soluble fertilizer and a preparation method thereof. Background technique [0002] Granular water-soluble fertilizer is a new type of water-soluble fertilizer that is granular, easy to water-soluble, and contains a large number of elements, humic acid, fulvic acid, amino acids and other nutrients. Granular water-soluble fertilizer contains nitrogen, phosphorus, and potassium, which are needed by plants. The nitrogen is composed of nitrate nitrogen, amide nitrogen, ammonium nitrogen and other nitrogen sources. It does not contain biuret, which improves the absorption and utilization of chemical fertilizers. The phosphorus and potassium in it are water-soluble phosphorus and potassium, and there is no residue in crop absorption, and the side effects on the soil are relatively small. The humic acid in the granular water-soluble fertilizer is of great help to imp...
