Problems solved by technology

The application range of these two dosage forms is relatively narrow, and they can only be used as topdressing fertilizers such as foliar spraying and drip irrigation of crops. They cannot be used as topdressing fertilizers or base fertilizers like the fully water-soluble granular type.
In addition, the trace elements on the market generally exist in the form of a single compound, and there are very few compound fertilizers that chelate six trace elements together and exist in the form of particles

Embodiment 1

[0041] A fully water-soluble chelated granular trace element water-soluble fertilizer according to the present invention comprises a composite chelated trace element component and a water-soluble filler, and the mass ratio of the composite chelated trace element component to the water-soluble filler is 2:3 ;

[0042] Wherein the compound type chelated trace element component comprises the following components according to the mass fraction:

[0043] EDTA 4%;

[0044] Citric acid 5%;

[0045] Water soluble chitin 3%;

[0046] Boron zinc iron manganese copper molybdenum material 88%.

[0047] Boron, zinc, iron, manganese, copper and molybdenum materials include the following components: zinc sulfate heptahydrate, sodium iron ethylenediamine tetraacetate, copper sulfate pentahydrate, manganese sulfate monohydrate, molybdenum chelated with EDTA;

[0048] The proportion of each component in the boron zinc iron manganese copper molybdenum material in the composite chelated trace e...

Embodiment 2

[0062] Such as figure 1 As shown, the pair-roll extrusion granulator includes a support frame, and the support frame includes a hopper, a primary molding device, a secondary molding device and a material collection box in sequence from top to bottom.

[0063] The feeding hopper is in the shape of a funnel with an open measuring end and a large top and a small bottom. The primary molding device is connected below the feeding hopper; the primary molding device includes a primary forming outer cylinder, and at least one pair of sheet material forming pairs are arranged in the primary forming outer cylinder. The two ends of the pair of sheet material forming rollers are respectively installed on the side wall of the primary forming outer cylinder through the bearing seat; the sheet material extrusion forming gap is set between the sheet material forming pair of rollers arranged in pairs; The outer roll surface of the material forming pair of rollers is a smooth cylindrical surface...

Abstract

The invention discloses a full-water-soluble chelated particle microelement water-soluble fertilizer and a preparation process thereof, and belongs to the technical field of production of microelement water-soluble fertilizers. The fertilizer is characterized by comprising a compound chelated microelement component and a water-soluble filler, and the mass ratio of the compound chelated microelement component to the water-soluble filler is 2: 3; wherein the compound chelated microelement component comprises the following components in percentage by mass: 4% of EDTA; 5% of citric acid; 3% of water-soluble chitin; and 88% of boron-zinc-iron-manganese-copper-molybdenum material. The problem that the application range of the microelement water-soluble fertilizer is limited due to the absence of particles can be solved; in addition, the problem that various microelements cannot be effectively supplemented to the soil at the same time can be solved.

Description

technical field [0001] The invention belongs to the technical field of production of trace element water-soluble fertilizers, and in particular relates to a fully water-soluble chelating particle trace element water-soluble fertilizer. Background technique [0002] At present, there are mainly two dosage forms for the use of trace element water-soluble fertilizers: one is liquid and the other is powder. The application range of these two formulations is relatively narrow, and they can only be used as topdressing fertilizers such as foliar spraying and drip irrigation of crops. They cannot be used as topdressing fertilizers or base fertilizers like the fully water-soluble granular type. In addition, the trace elements on the market generally exist in the form of a single compound, and there are very few compound fertilizers that chelate six trace elements together and exist in the form of particles. [0003] In view of this, the applicant has developed a fully water-soluble ...
