Problems solved by technology

This method is only applicable to enterprises that have the right to use and store ammonia. Since ammonia has major safety hazards such as flammability, explosion, and high toxicity, ammonia storage of more than 10 tons constitutes a major source of danger. However, many compound fertilizer manufacturers cannot obtain the right to use and store ammonia, so this method has great limitations

preparation example Construction

[0033] The preparation method of the above-mentioned green and environment-friendly nitrogen and potassium topdressing fertilizer containing various nitrogen elements comprises the following steps:

[0034] (1) In the production of compound fertilizer by pellet method, urea, ammonium bicarbonate, ammonium sulfate, potassium nitrate, potassium chloride, humic acid, sepiolite, calcium hydroxide and other materials containing trace elements and plant growth regulators are passed through After the microcomputer metering, it enters the drum granulator. During the granulation process, the viscosity of urea nitrate and sepiolite produced by the reaction of potassium nitrate and urea is used as the adhesive, and the water produced by the decomposition of ammonium bicarbonate is used as the liquid phase. The ammonia gas produced by the decomposition of ammonium bicarbonate completes the ammonification treatment of potassium nitrate to control the quality of urea nitrate produced by the ...

Abstract

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 the purposes of improving soil, reducing soil salinity, improving nutrient element absorption of plants, increasing plant quality and productivity and improving plant disease resistance.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizers, and in particular relates to a green and environment-friendly nitrogen and potassium topdressing fertilizer containing various nitrogen elements and a preparation method thereof. Background technique [0002] Global agricultural production is developing in the direction of green agriculture and environmentally friendly agriculture. This is the development trend of world agriculture and the way out for the sustainable development of China's agriculture. China's arable land accounts for 7% of the world's total, but uses 35% of the world's chemical fertilizers. China has become the world's largest producer and consumer of chemical fertilizers, but it has also become the largest waste country. Long-term large-scale use of chemical fertilizers is increasing crop production. At the same time, it also caused serious soil, air and water pollution. Topdressing is an important part of crop fe...
