preparation example Construction

[0019] On the basis of above-mentioned organic fertilizer compatibility, the present invention further proposes the preparation method of above-mentioned organic fertilizer, and method comprises the following steps:

[0020] S10, adding biochemical fulvic acid and trace elements to the amino acid waste liquid, stirring for 1-3 hours, to obtain a premixed slurry;

[0021] S20, adding a large number of elements, weathered coal humic acid, boron mud, synergist, and fillers into the premixed slurry in step S10, fully stirring, spraying and granulating.

[0022] Wherein in step S10, in order to facilitate more sufficient reaction and combination of components, the stirring reaction conditions can be controlled at 30°C-60°C.

[0023] It can be seen from the steps of the above-mentioned method of the present invention that the long-term stacking of amino acid waste liquid and boron mud is difficult to handle, and the cheap amino acid waste liquid is used to add biochemical fulvic aci...

Embodiment 1

[0026] S00, obtain raw material according to following composition ratio in this embodiment 1: biochemical fulvic acid 80kg, amino acid waste liquid 500kg, trace element (zinc sulfate, ferrous sulfate, manganese sulfate) 10kg, weathered coal humic acid 120kg, Boron mud 10kg, macroelements (equivalent monoammonium phosphate, potassium sulfate, ammonium sulfate) 200kg, carboxyethyl cellulose 3kg, bentonite 77kg;

[0027] S01, first add 80kg of biochemical fulvic acid to 500kg of amino acid waste liquid in the stirring tank, stir well, then add 10kg of trace elements, and control the temperature at 50°C for 1 hour;

[0028] S02, add 120kg of weathered coal humic acid, 10kg of boron mud, 200kg of macroelements, 3kg of carboxyethyl cellulose, and 77kg of bentonite into the mixing tank, mix well and spray granulate.

Embodiment 2

[0030] S00, obtain raw material according to following composition ratio in this embodiment 2: biochemical fulvic acid 100kg, amino acid waste liquid 375kg, trace element (manganese sulfate: copper sulfate: ferrous sulfate mass ratio is 1:2:1) 15kg, weathering Coal humic acid 100kg, boron mud 50kg, macroelements (urea: monoammonium phosphate: potassium sulfate mass ratio is 3:2:3) 175kg, carboxymethyl cellulose 3kg, polyvinyl alcohol 2kg, zeolite powder 50kg, diatomaceous earth 50kg, bentonite 25kg;

[0031] S01, first add biochemical fulvic acid to the amino acid waste liquid in the stirring tank and stir thoroughly, then add trace elements, and control the temperature at 60°C for 1.5 hours;

[0032] S02, add weathered coal humic acid, boron mud, macroelements, carboxyethyl cellulose, and bentonite into the mixing tank, mix thoroughly and then spray and granulate.

Abstract

The invention discloses organic fertilizer. The organic fertilizer comprises, by mass, 35-75 parts of amino acid waste liquid, 5-20 parts of biochemical fulvic acid, 0.8-3 parts of trace elements, 10-20 parts of weathered coal humic acid, 0.1-10 parts of boric sludge, 15-35 parts of major elements, 0.3-1 part of synergist and 10-25 parts of filler. The organic fertilizer has the advantages that the amino acid waste liquid is used as the main raw material to provide various amino acids, the amino acid waste liquid is combined with the biochemical fulvic acid to form double chelating agents to chelate the medium trace elements, then the boric sludge, the mineral-source humic acid and the synergist are added, and quick action and long-term action are combined to provide lasting fertility forcrops; the organic fertilizer is simple in raw material acquiring and processing, environmentally friendly, free of pollution, low in cost and high in economic benefit.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer preparation, in particular to an organic fertilizer and a preparation method thereof. Background technique [0002] my country is a large agricultural country with a large population and little land. The increase in food production mainly depends on the large-scale application of chemical fertilizers, so that it has 10% of the world's arable land but consumes 30% of the world's chemical fertilizers. At present, my country's land is mainly faced with problems such as excessive fertilization and blind fertilization resulting in soil compaction, decline in organic matter, reduction of beneficial microorganisms, and soil acidification. [0003] In response to the above problems, a variety of organic fertilizers with long-term improvement effects are increasingly used to replace traditional fertilization. Organic fertilizer can improve soil, improve soil fertility, restore soil to normal ec...
