Water-soluble liquid fertilizer containing high-concentration amino acid, and preparation process thereof

Abstract

The invention provides a water-soluble liquid fertilizer containing high-concentration amino acid, and a preparation process thereof, wherein the fertilizer comprises, by mass, 50-55 parts of bone gelatin, 20-25 parts of urea, 8-10 parts of potassium dihydrogen phosphate, 3-5 parts of magnesium sulfate heptahydrate, 0.2-0.5 part of zinc sulfate monohydrate, 0.2-0.5 part of borax, 49-51 parts of ahydrochloric acid solution, 5-8 parts of a carboxymethyl cellulose aqueous solution and 100-120 parts of water. According to the invention, the liquid fertilizer does not contain any plant growth hormones, is environmentally-friendly, has remarkable effect, achieves stable colloid after being compounded with chemical nutrition elements, does not flocculate, does not precipitate and layer after being placed for a long time, can be widely applied to modern agricultural facilities such as drip irrigation and the like, and has important popularization value.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a fertilizer containing high-concentration amino acid aqueous solution and a preparation process thereof. Background technique [0002] Amino acids are the smallest molecules that make up biological proteins, and are also the most basic substances related to biological life activities. Amino acids can be directly absorbed and utilized by plants without transformation, and have the functions of improving crop disease resistance and crop quality. In addition, supplementing the essential amino acids of plants can stimulate and regulate the rapid growth of plants, chelate trace elements, promote the absorption of nutrients by plants, enhance plant metabolism, improve plant photosynthesis, and promote the development of plant roots. [0003] At present, there are two main ways to prepare high-concentration amino acid liquid fertilizers: one is to directly dissolve and...

Problems solved by technology

[0003] At present, there are two main ways to prepare high-concentration amino acid liquid fertilizers: one is to directly dissolve and prepare amino acid raw powders. However, due to the different composition and content of amino acid components in different sources of amino acid raw powders, it is difficult to maintain the quality of the finished amino acid liquid fertilizers. At the same time, because amino acid raw powder is easy to absorb moisture, agglomerate and infect miscellaneous bacteria during transportation and storage, it will also bring inconvenience to the production enterprise; the second is to use some animal and plant raw materials, such as bean cake, rice bran, bran, bone meal, etc. The raw materials are hydrolyzed by biological enzyme method or chemical method, but because these raw materials have low protein content and many impurities, the amino acid content in the amino acid liquid fertilizer obtained after hydrolysis is low, which is difficult to meet the needs of plant growth for amino acids, resulting in some production Enterprises add plant growth hormone, which is still controversial in academia, to a wide range of finished products to improve product effects. Third, the amino acid solution prepared after hydrolysis is unstable after compounding chemical nutrients, and flocs are prone to appear. It is also prone to stratification, precipitation and other phenomena, which are greatly affected in the modern agricultural facilities that promote the integration of water and fertilizer, such as drip irrigation, which limits the popularization and application of amino acid liquid fertilizer
