Problems solved by technology

[0002] Rice is a food crop that needs a lot of fertilizer. In terms of rice fertilization, many farmers like to use single-nutrient quick-acting fertilizers, such as applying a large amount of inorganic nitrogen fertilizers. This will not only cause serious loss of fertilizers, but also reduce the utilization rate of nitrogen fertilizers, which needs to be solved urgently

Abstract

The invention discloses a preparation method of a special rice fertilizer with comprehensive nutrients, comprising the following steps: stirring sodium nitrate, ammonium sulfate, a potassium magnesiumphosphate fertilizer, vermiculite powder, fly ash, Chinese medical stone powder, borax and coconut shell carbon powder, sending the materials into a melting tank and heating and stirring, heating andcontinuously stirring, and filtering to obtain a melt; mixing furfural residue, corn germ meal, fermented oil residue, pigeon dung, propolis, magnesium citrate and ferrous sulfate, adding water, grinding, heating, adding an ammonium chloride compound and the melt and uniformly mixing to obtain pulp, sending the pulp into a rotary pulp shooting machine (a pulp shooting port of the rotary pulp shooting machine is positioned above a drying tower), letting the pulp be sprayed into fertilizer drops above the drying tower from the pulp shooting port of the rotary pulp shooting machine, and settlingand drying in the drying tower so as to obtain the special granular rice fertilizer. The preparation technology is simple. The fertilizer has more comprehensive and balanced nutrients and can be usedto efficiently provide rice with nutrients for a long time. Labor cost is low, labor force can be saved, and environmental pollution is reduced.
