Nitrogen fixation amino acid multi-element dressing fertilizer

Abstract

The invention discloses a nitrogen fixation amino acid multi-element dressing fertilizer. The nitrogen fixation amino acid multi-element dressing fertilizer is characterized in that the nitrogen fixation amino acid multi-element dressing fertilizer is prepared from the following components in parts by mass: 21% to 25% of powdery urea, 7% to 9% of ammonium sulfate, 24% to 28% of ammonium chloride, 16% to 18% of potassium chloride, 12% to 15% of amino acids, 4% to 7% of a medium element composition, 0.3% to 0.6% of a trace element composition, 3% to 5% of an adhesive and 1% to 3% of a nitrogen fixation fungicide, wherein the weight ratio of powdery urea, ammonium sulfate to ammonium chloride is 3: 1: 3.5. Chelation is carried out on the amino acids, the medium element composition and the trace element composition through magnetization and stirring, other preparation ingredients are added, and after palletizing and low-temperature drying, the nitrogen fixation amino acid multi-element dressing fertilizer is prepared. According to the fertilizer disclosed by the invention, the absorption and utilization of crops for nitrogen, mineral elements and the amino acids can be improved, the crop yield, lodging resistance and capacity for preventing plant diseases and insect pests are improved, and the growth of a root system and crops is promoted.

Description

technical field

[0001] The invention belongs to the technical field of fertilizer processing, and in particular relates to a nitrogen-fixing amino acid multi-element topdressing fertilizer. Background technique

[0002] The nitrogen fertilizers commonly used by farmers are mainly urea and ammonium bicarbonate. Due to unstable chemical properties and unreasonable use of urea and ammonium bicarbonate, the utilization rate is very low, resulting in waste of resources and energy and pollution to the environment. Urea is the most important nitrogen fertilizer, accounting for more than 60% of the total nitrogen fertilizer. It is an amide nitrogen fertilizer with a nitrogen content of up to 46%. After use, the soil will not compact, salinize, or acidify, and is suitable for a variety of crops and soils; However, after being applied to the soil, some of them are converted into nitrate nitrogen or gaseous nitrogen and are easily lost, and the utilization rate of nitrogen in urea is ...
