Abstract
The invention relates to an instant chelated solid water-soluble fertilizer, particularly a chelated water-soluble fertilizer capable of heating a solution, belonging to the field of crop fertilizers. The water-soluble fertilizer comprises 25-40% of urea, 10-20% of potassium dihydrogen phosphate, 10-25% of double superphosphate, 10-25% of potassium sulfate, 2-6% of magnesium chloride, 0.5-3% of zinc sulfate, 0.5-3% of manganese sulfate, 0.5-4% of sodium molybdate, 0.5-2% of ferrous sulfate, 2-8% of chelator and 4-10% of heating agent. The preparation method of the water-soluble fertilizer comprises the following steps: carrying out ammonification pretreatment on double superphosphate for later use, chelating microelements with a chelator to obtain a chelated mixture, thoroughly mixing the treated double superphosphate, chelated mixture, macroelements and heating agent, pulverizing and packaging to obtain the instant chelated solid water-soluble fertilizer. The water-soluble fertilizer contains abundant microelements and overall nutrients; and the heating agent can increase the dissolution temperature, thereby enhancing the solubility of the components, increasing the dissolution rate and reducing the water consumption. The microelements are chelated by the chelator, thereby promoting the absorption and utilization of plants for macroelements and microelements; and thus, the fertilizer is suitable for various crops.
