description The invention discloses an environment-friendly nitrogen potassium dressing fertilizer containing various nitrogen elements and a preparation method thereof. The fertilizer comprises, by weight, at least 20% of urea, 5-7% of ammonium bicarbonate, 7-15% of ammonium sulfate, 10-14% of nitrate, at least 8% of potassium chloride, 7% of humic acid, 8-12% of sepiolite, 5-7% of calcium hydroxide, other materials containing trace elements and a plant growth regulator. In a granulating process, urea nitrate generated by reaction of nitrate and urea and sepiolite with viscosity are used as adhesive, water generated by decomposing of ammonium bicarbonate is used as a liquid phasor, steam is used for increasing the temperature of granulating materials, liquid phasor required by granulation is supplemented, and a material granulating process is finished. The final product contains nitrate nitrogen, ammonium nitrogen, amidonitrogen, organic matters, various medium trace elements and the plant growth regulator and achieves
