| description | The invention relates to the technical field of fertilizer processing and particularly relates to a preparation method of a fertilizer with quick-acting and slow-release functions. The preparation method comprises the following steps: humic acid enveloping: granulating diammonium phosphate, spraying a layer of binder, and spraying a layer of peat; and sulfur enveloping: spraying compound fermenting bacteria powder to the surfaces of humic acid enveloped particles, dipping the particles into chitosan/sulfur suspension liquid, and heating until liquid is completely absorbed. The fertilizer prepared by virtue of the preparation method has long-acting property and quick-acting property, nutrients of medium trace element and nutrients of macroelements are synchronously released, and multiple elements are commonly coordinated and promoted, so that the utilization rate of the fertilizer can be effectively increased, the topdressing number of times is reduced, the nutrient loss is reduced, thesolidification of the nu |
