Embodiment Construction

[0023] Embodiments of the invention:

[0024]The present invention is constituted as follows: it is mixed with humic acid and pyrite slag in a weight ratio of 25-50%: 10-15%, and then mixed with nitrogen, phosphorus, potassium fertilizer and other Medium and trace elements are processed into long-acting semi-finished products and quick-acting semi-finished products, and then the two semi-finished products are measured and mixed in a certain proportion according to the growth characteristics of various crops.

[0025] Specifically, it can use 15% urea, 5% ammonium sulfate, 5% ammonium chloride, 5% monoammonium phosphate, 8% calcium magnesium phosphate fertilizer, 10% potassium chloride or potassium sulfate, iron pyrite slag 10% of waste residue, 25% of humic acid, 5% of phosphogypsum, and 5% of dolomite powder are crushed, mixed, granulated, dried, cooled, sieved, and slow-release coated to obtain (long-acting) semi-finished products in a certain proportion. . Then make humic...

Abstract

The invention discloses a rapid long-acting humic acid multivariate fertilizer and a production method thereof. A long-acting part of the rapid long-acting humic acid multivariate fertilizer comprises raw materials of, by weight, 15-20% of urea, 5-10% of ammonium sulfate, 5-10% of ammonium chloride, 5-15% of monoammonium phosphate, 8-15% of calcium magnesium phosphate, 10-20% of potassium chloride or potassium sulfate, 10-15% of waste residues left from iron selection of pyrite smelting slag, 25-50% of humic acid, 5-25% of phosphogypsum and 5-12% of dolomite powder; A rapid part comprises rawmaterials of, by weight, humic acid urea prepared from 20-30% of urea and 40-50% of instant humic acid, 5-15% of monoammonium phosphate, 10-20% of potassium chloride or potassium sulfate, 0.5-1% of borax, 1-3% of zinc sulfate, 2-5% of magnesium sulfate, 0.2-1% of copper sulfate and 0.01-0.05% of ammonium molybdate.

Description

technical field [0001] The invention relates to a quick-acting and long-acting fertilizer for agricultural production and a production method thereof, belonging to the technical field of compound fertilizer production. Background technique [0002] The fertilizer effect period of existing compound fertilizers in my country is limited by nitrogen, phosphorus, and potassium fertilizers, and the fertilizer effect period is very short, generally 50-60 days, which cannot meet the nutrient needs of crops throughout the growth period, which limits farmers' choice of compound fertilizers enthusiasm. There are also the following deficiencies: low nutrient utilization rate, unreasonable ratio of fertilizer and nutrient, etc. According to measurements, the utilization rate of ordinary compound fertilizers in my country is less than 29%, which is more than 10 percentage points lower than foreign products, which not only reduces the overall application effect of fertilizers, but also inc...
