when materials are fermented at low temperature, gas is generated in the placing barrel 2, the gas is sprayed out through the first pipeline and impacts the placing barrel 2, and the gas enables the placing barrel 2 to float on the water surface; the materials placed in the barrel 2 are fermented to generate heat, meanwhile, the heat promotes the fermentation of the materials, and the fermentation of the materials and the heat generation of the materials are mutually promoted, so that the fermentation of the materials is facilitated to be accelerated; s3: uniformly stirring the low-temperature mixed material obtained in the step S1, continuing to perform high-temperature fermentation in the placing barrel 2 for 6-7 days, wherein the initial temperature of the material before the high-temperature fermentation in the placing barrel 2 is 80 ℃, after the high-temperature fermentation, the temperature of the material rises to 150 ℃, the water content is reduced to 40% -50%, and then, the temperature is raised to 240 ℃ again to obtain a high-temperature fermented material; after the materials are placed in the placing barrel 2 for fermentation for 6-7 days, the materials generate biogas, the biogas enters a pre-installation cavity at the upper end part of the mixing equipment 1 through a spiral pipe, then the biogas in the pre-installation cavity is communicated with a combustion stove at the bottom of the mixing equipment 1 through a second pipeline, the biogas is combusted on the combustion stove and acts on the bottom of the mixing equipment 1, then water in the mixing equipment 1 is heated slowly, and after the water is heated, high-temperature water acts on the materials in the placing barrel 2 and accelerates the fermentation of the materials; s4: adding a low-temperature microbial inoculum into the high-temperature fermentation material obtained in the step S2; after the addition is finished, carrying out alcoholization drying for 2-3 days to obtain an alcoholized material, wherein the water content of the alcoholized material is 20% -25%, then hanging a bacterial film on the surface of the alcoholized material, cooling by air, and carrying out quenching treatment on the alcoholized material to make the alcoholized material in an ice block shape; after the alcoholized material is frozen, crushing the alcoholized material to form powder, then adding one or more of hydrogen ammonium carbonate, potassium nitrate, calcium nitrate and calcium ammonium nitrate which take N element as a carrier, wherein the addition amount of the one or more of the hydrogen ammonium carbonate, the potassium nitrate, the calcium nitrate and the calcium ammonium nitrate is 5-10% of the total mass, and standing the mixture for 1-2 days to prepare the POD value-added fertilizer; compared with the granular fertilizer, the fertilizer is more powdery, the efficiency of absorbing the powder by soil is higher, and the fertilizer is convenient to apply, so the materials are finely powdered, quenched and frozen after alcoholization, and then crushed to form the powder; during the growth of the plant, the N element can promote the growth of plant branches and leaves, promote the growth of plant fruits and strengthen the root system of the plant.
