Preparation method of macroelement water-soluble fertilizer rich in seaweed active ingredients

Abstract

The invention provides a preparation method of a macroelement water-soluble fertilizer rich in seaweed active ingredients. The preparation method of the macroelement water-soluble fertilizer rich in seaweed active ingredients comprises the following steps: S1, extracting 6.3 parts of ascophyllum nodosum slurry, introducing the ascophyllum nodosum slurry into a reaction kettle, and sequentially adding 4.35 parts of urea powder, 1 part of monopotassium phosphate, 0.23 part of potassium hydroxide and 0.05 part of EDTA copper; and S2, filtering and sub-packaging the liquid which is uniformly stirred and completely melted in the step S1 to obtain the water-soluble fertilizer. The reaction kettle comprises: a main body; a driving mechanism; a stirring mechanism, which comprises a stirring plate, a supporting rod, a supporting ring, a blade and a rubber rod, wherein the stirring plate is slidably connected with the interior and the inner side wall of the main body, and the blade with an arc-shaped side wall is installed in the supporting ring; a connection mechanism; a discharging mechanism; a material spraying mechanism; a material receiving mechanism; a closing mechanism; and a reset spring. The preparation method of the macroelement water-soluble fertilizer rich in seaweed active ingredients has the advantages of promoting crop growth and improving the utilization rate of macroelements.

Description

technical field [0001] The invention relates to the technical field of water-soluble fertilizer processing, in particular to a preparation method of a water-soluble fertilizer rich in seaweed active ingredients and macroelements. Background technique [0002] Seaweed fertilizer uses advanced technology to break the cell wall of seaweed, release the content, and concentrate to form seaweed essence, thereby retaining the rich minerals and trace elements in seaweed, and also contains a certain amount of polyphenol compounds, seaweed polysaccharides and A large number of growth regulators, such as cytokinins, auxins, cytokinin-like factors, cytokinins, abscisic acid, gibberellins, ethylene, betaine, polyamines, trans-N6-isopentenyl adenine and Its derivatives, aminocyclopropane carboxylic acid, ethylene precursor, indole acetic acid, indole compound, etc., have greatly retained the pure natural active ingredients, and also contain a large amount of potassium, calcium, magnesium,...

AI Technical Summary

Problems solved by technology

[0003] The active ingredients of seaweed can maintain their original state to the greatest extent, and the use effect will be the best. However, most manufacturers at home and abroad mainly use chemical hydrolysis to produce seaweed fertilizer. The biggest disadvantage of chemical hydrolysis is that strong alkali and high temperature destroy the seaweed. The activity of the source material reduces the use effect of seaweed fertilizer; after the water-soluble fertilizer is produced in the reactor, in the process of discharging the water-soluble fertilizer, due to the relatively thick water-soluble fertilizer, the water-soluble fertilizer adheres to the inner wall of the reactor, causing waste
