Abstract
The invention relates to the technical field of nitrogen fertilizer production, and discloses a multifunctional nitrogen fertilizer which comprises the following raw materials in percentage by mass: 55-62% of basic raw materials, 9-10% of medium trace elements, 8-10% of plant nutrition conditioning agents, 3-5% of nitrogen fertilizer synergists and 11-13% of biochar, wherein the basic raw materials consist of the following raw materials in percentage by mass: 45-50% of urea, 11-12% of synthetic ammonia, 3-5% of ammonium bicarbonate, 3-5% of ammonium chloride, 4-6% of multifunctional additive, 1-3% of nitric acid, 1-3% of bentonite, 2-4% of calcium chloride, 3-4% of sodium octaborate tetrahydrate and 5-6% of liquid fertilizer, wherein the medium trace elements consist of the following raw materials in percentage by mass: 4-6% of calcium, 4-6% of magnesium, 4-6% of sulfur, 6-7% of carbon, 10-12% of nitrogen, 9-11% of phosphorus, 9-12% of potassium, 7-9% of greenhouse, 8-10% of manganese, 6-8% of copper and 7-8% of zinc. The medium trace elements, the plant nutrition conditioner, the nitrogen fertilizer synergist, the biochar and the hydrous aluminosilicate mineral are added into the original raw materials for preparing the nitrogen fertilizer, so that the absorption of the plant to the nutrition elements is promoted, the utilization rate of the nitrogen fertilizer is improved, and the multifunctional nitrogen fertilizer is achieved.
