High-efficiency multifunctional foliage fertilizer and production method thereof

Abstract

The invention discloses a high-efficiency multifunctional foliage fertilizer and a production method thereof. The foliage fertilizer is prepared by chelating shrimp processing leftovers, which serve as the main raw material, with medium and minor elements. The foliage fertilizer is prepared from 10-30% of amino acids, 2-8% of medium and minor elements, 10-30% of organic nitrogen, 3-20% of phosphorus, 3-20% of potassium, and 10-30% of shrimp peptide protein, chitosan, chitosan oligosaccharide, chitin, glucosamine hydrochloride, astacin and shrimp cephalin. The foliage fertilizer disclosed by the invention enhances the low-temperature tolerance, drought tolerance, salt damage tolerance, chemical damage tolerance and other stress tolerances of crops on the premise of comprehensively and efficiently supplementing necessary nutrients for crops, and has the functions of restoring the wound in the root system, enhancing the disease resistance of the crops, inhibiting disease and pest and the like. The production technique can reduce the acidolysis consumption, avoids introducing abundant inorganic salts and chloride ions to destroy soil ecological equilibrium and influence plant growth, lowers the energy consumption and requirements for equipment strength, and can implement the clean production of complete utilization and zero pollution discharge.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a high-efficiency multifunctional foliage fertilizer and a production method thereof. Background technique [0002] Shrimp processing will produce about 35% to 45% of shrimp head, shrimp shell and other scraps. It is estimated that more than 400,000 tons of shrimp processing scraps will be produced every year in my country. Shrimp scraps are rich in protein and 18 kinds of active amino acids , the content of hydrolyzed amino acid is as high as 42%, and it also contains chitin and chitosan with broad-spectrum bactericidal and antibacterial effects, astaxanthin and shrimp cephalin that can strengthen immune function and induce cell division, and active calcium that regulates soil acid-base balance Magnesium and other ingredients with extremely high nutritional value have unique effects on crop growth, fruit quality improvement, pest control, soil improvement, and ecological environment. It...

AI Technical Summary

Problems solved by technology

The amount of acid and alkali used in the above method is large, and a large amount of inorganic salts will be introduced in the neutralization process. At the same time, a large amount of chloride ions introduced in the production process are difficult to remove, which is not good for soil and crop growth.

In addition, the prepared amino acid fertilizers are all in a liquid state, are not easy to adhere to the leaf surface, have a low nutrient absorption rate, and have low amino acid content, few types, incomplete nutrition, and no medicinal function

[0005] Some processes in the prior art utilize crustaceans such as rotten stinky shrimp, dead crabs, locusts, and silkworm chrysalis to prepare amino acid fertilizers. The source of raw materials is limited, and, with rotten animal corpses as raw materials, putrescine (butyrine) will be produced due to the decomposition of bacteria. Diamine), cadaverine and other highly toxic gases, the production process and products are difficult to meet the requirements of green environmental protection and clean production

In addition, during production, the method of separating shrimp and crab shells from crustaceans and then hydrolyzing them causes complicated pre-treatment work in the production process

[0006] On the other hand, the production cost of chitosan and chitosan oligosaccharide is high, and it has not been applied in the field of fertilizer in actual production.

In addition, the existing acid-base hydrolysis process of fertilizers leads to low protein hydrolysis and more precipitation

And when hydrolysis is carried out with hydrochloric acid, chloride ions are inevitably introduced, which will be difficult to remove afterwards, which will affect the quality of fertilizers, and will also cause soil pollution and crop quality decline

[0007] From the prior art, there is no report on the same preparation method and the new green high-efficiency multifunctional foliar fertilizer product prepared therefrom
