Problems solved by technology

The chemical properties of a wide variety of trace elements are very different. Some soluble trace elements are prone to antagonism between trace elements, and even precipitate. When trace elements are applied to the soil or leaves, they are extremely difficult to tolerate and cannot be absorbed; there are also some trace elements that are suitable for different solute environments, and simple mixing will change their chemical properties
Existing commonly used inorganic trace element water-soluble fertilizers contain a large amount of sulfate ions, chloride ions and phosphate ions, etc. Long-term large-scale application will lead to problems such as soil compaction and acidification

Abstract

The invention discloses special chelated microelement water-soluble fertilizer for oil-tea camellia. The special chelated microelement water-soluble fertilizer is prepared from amino acid chelated manganese, amino acid chelated iron, amino acid chelated copper, amino acid chelated zinc and an additive, wherein the additive is prepared from disodium octaborate tetrahydrate and ammonium molybdate. The invention aims at providing the special chelated microelement water-soluble fertilizer for the oil-tea camellia; the microelement water-soluble fertilizer contains iron, zinc, copper, manganese, boron and molybdenum elements with a scientific proportion; all the manganese, copper, iron and zinc elements of the microelement water-soluble fertilizer have an amino acid chelated state, so that themicroelement water-soluble fertilizer has the characteristics of quick-acting releasing and rapid absorption, and also has the advantages of long-acting slow release and low possibility of being lost;a condition that the elements have a mutual effect so that antagonized absorption or precipitation is caused does not easily occur.

Description

technical field [0001] The invention belongs to a fertilizer, in particular to a water-soluble fertilizer with chelated microelements special for camellia oleifera and a preparation method thereof. Background technique [0002] Among the existing fertilizers, there is currently no chelated trace element water-soluble fertilizer for Camellia oleifera, and most of the trace element water-soluble fertilizers are inorganic or organic complexed. [0003] Common inorganic trace element water-soluble fertilizers are mostly in the form of inorganic salt ions or insoluble slag oxides, such as sulfate, slag, waste residue, glass silicate, etc.; organic complex trace element water-soluble fertilizers are mostly citric acid Complex molecules or ions formed by binding ligands such as oxalic acid, EDTA and metal ions with coordination bonds. The chemical properties of a wide variety of trace elements are very different. Some soluble trace elements are prone to antagonism between trace el...
