Nitrogen-phosphorus-potassium compound fertilizer capable of improving stress resistance and preparation method of nitrogen-phosphate-potassium compound fertilizer

Abstract

The invention discloses a nitrogen-phosphorus-potassium compound fertilizer capable of improving stress resistance. The nitrogen-phosphorus-potassium compound fertilizer is prepared from the following raw materials in parts by weight: 30-33 parts of potassium feldspar, 30-33 parts of phosphate ores, 130-135 parts of 65% phosphoric acid solution, proper amount of concentrated ammonia water, 8-9 parts of radix scutellariae, 18-20 parts of shells, 20-22 parts of peanut shells, 1-1.2 parts of glucose, 3-4 parts of nano carbon powder, 0.1-0.2 part of abscisic acid, 14-15 parts of modified starch, 6-7 parts of carboxymethyl chitosan, 5-6 parts of isopropanol, 10-11 parts of 40% sodium hydroxide solution, 22-24 parts of 50% 3-chloro-2-hydroxypropyl trimethylammonium chloride solution, proper amount of 10% hydrochloric acid solution, proper amount of 80% methanol solution, proper amount of absolute ethyl alcohol, 3-4 parts of polyvinyl alcohol and 1-1.2 parts of microorganism bacterium powder. Reaction products of the potassium feldspar, the phosphate ores and the phosphoric acid are leached with water to obtain soluble phosphorus and potassium components; after the carboxymethyl chitosan is reacted, ions with different charges dissolved out from inner cores of the fertilizer are adsorbed by static electricity and a slow releasing performance of the fertilizer is enhanced; and the stress resistance of crops can be improved by the fertilizer.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a nitrogen, phosphorus and potassium compound fertilizer capable of improving stress resistance and a preparation method thereof. Background technique [0002] Fertilizer occupies an important position in agricultural production, is the largest material investment in agricultural production, and is one of the most important means of production in agricultural production. The most important nutrients needed by plants during the growth process are nitrogen, phosphorus and potassium. Most of them are absorbed by plants in the form of calcium phosphate, nitrate or ammonium ions and potassium ions. Among them, calcium and phosphate ions are The soil is produced continuously during the weathering of stones, and only a small amount of nitrogen exists in the soil in the form of ammonium ions, and most of it exists in the organic soil in the form of organic nitrogen and othe...

Problems solved by technology

At present, the world generally extracts potassium from soluble potassium ore or directly uses potassium salt minerals as raw materials to manufacture potassium fertilizers. my country's water-soluble potassium ore resources are seriously scarce, lacking large soluble potassium salt deposits, and the distribution is very uneven
