Abstract

The invention discloses a special sustained and controlled release fertilizer for flowers, and a preparation method thereof. The fertilizer comprises, by mass, 25-30 parts of a nitrogen fertilizer, 8-12 parts of a phosphorus fertilizer, 12-16 parts of a potassium fertilizer, 25-40 parts of fermented ground beetle dung, 2-5 parts of humic acid, 3-6 parts of composite amino acids, 2-5 parts of medium and trace elements, 1-2 parts of a bactericide and 1-3 parts of a coating agent. The preparation method comprises the following steps: mixing and granulating the nitrogen fertilizer, the phosphorus fertilizer, the potassium fertilizer, the fermented ground beetle dung, humic acid, the composite amino acids, medium and trace elements and the bactericide, smearing the coating agent on fertilizer granules through a fluidized bed coating technology, drying the coated granules, screening the dried granules, and detecting the screened granules to prepare the special sustained and controlled release fertilizer for flowers. Compared with fertilizers in the prior art, the fertilizer disclosed in the invention has the advantages of long effective period, meeting of nutrient demands of the whole growth period through one-shot fertilization, reduction of the fertilizer loss, fertilizer utilization rate improvement, realization of effective prevention and control of Pythium diseases through adding the bactericide, and reduction of the management and maintenance labor.
