Abstract

The invention relates to the field of composite fertilizers, and in particular to a whole-element composite fertilizer and a preparation method thereof. The whole-element composite fertilizer consists of the following raw materials in parts by weight: urea, triple superphosphate, potassium sulfate, monoammonium phosphate, potassium chloride, ammonium molybdate, boric acid, polypeptide alkali chelate zinc, citrate chelate copper, long-lasting additives, illite powder, attapulgite powder and humic acid ammonium. The preparation method comprises the following steps: preparing pretreated raw materials, mixing and stirring, crushing cakes, pelletizing by using a pelletizer, drying granules, cooling the granules, screening, coating finished granules so as to obtain a finished product, and the like. The invention provides the whole-element composite fertilizer which is capable of effectively replenishing organic matters and various medium-trace elements which are urgently required by soil, improving soil structures, improving permeability, and promoting nutrient absorption of crops, and the invention further provides the reasonable preparation method for the whole-element composite fertilizer.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to an all-element compound fertilizer and a preparation method thereof. Background technique [0002] Compound fertilizer refers to chemical fertilizers containing any two or three of crop nutrients nitrogen, phosphorus, and potassium made by chemical methods or (and) mixed methods. They have comprehensive nutrients and high content; good physical properties and easy application; side effects It has few ingredients and has no adverse effects on the soil; the ratio is diverse, which is conducive to targeted selection and application, and plays a very important role in balancing fertilization, improving fertilizer utilization efficiency, and promoting high and stable yields of crops. Generally divided into two categories of binary and ternary compound fertilizers, of which binary compound fertilizers include ammonium phosphate, nitrophosphate fertilizer, potassium dihydrogen phosph...
