preparation example Construction

[0030] The water-soluble fertilizer is prepared by the following preparation method of the water-soluble fertilizer.

[0031] Correspondingly, the embodiment of the present invention also provides a preparation method of water-soluble fertilizer. The method comprises the steps of:

[0032] S01. Based on the water-soluble fertilizer, weigh each component respectively;

[0033] S02. Mix nitrogen source, phosphorus source, potassium source, medium and trace elements, and rare earth nitrate to obtain water-soluble fertilizer.

[0034] The preparation method of the above-mentioned water-soluble fertilizer only needs to carry out the mixing treatment of the components obtained by weighing, so as to effectively ensure the stable performance of the water-soluble fertilizer. The preparation method of the water-soluble fertilizer is simple and quick, has low cost and is suitable for extensive production.

[0035] Specifically, in the above step S01, each component of the base water-s...

Embodiment 1

[0041] A water-soluble fertilizer comprising the following components by weight: 4 parts of ammonium nitrate; 3 parts of potassium chloride; 80 parts of potassium nitrate; 6 parts of ammonium dihydrogen phosphate; 3 parts of potassium dihydrogen phosphate; 0.8 part of boric acid ; 0.4 parts of zinc sulfate monohydrate; 0.3 parts of citric acid monohydrate; 2.4 parts of anhydrous magnesium sulfate; 0.1 parts of rare earth nitrate.

[0042] The preparation method of the water-soluble fertilizer comprises the following steps: taking each component of the water-soluble fertilizer according to the basis; 4 parts of ammonium nitrate; 3 parts of potassium chloride; 80 parts of potassium nitrate; 6 parts of ammonium dihydrogen phosphate; Potassium hydrogen; 0.8 parts of boric acid; 0.4 parts of zinc sulfate monohydrate; 0.3 parts of citric acid monohydrate; 2.4 parts of anhydrous magnesium sulfate;

Embodiment 2

[0044] A water-soluble fertilizer, the water-soluble fertilizer comprises the following components by weight: 5 parts of ammonium nitrate; 5 parts of potassium chloride; 85 parts of potassium nitrate; 10 parts of ammonium dihydrogen phosphate; 20 parts of potassium dihydrogen phosphate; 0.9 part of boric acid ; 0.5 parts of zinc sulfate monohydrate; 2.5 parts of anhydrous magnesium sulfate; 0.5 parts of rare earth nitrate.

[0045] The preparation method of the water-soluble fertilizer comprises the following steps: taking each component of the water-soluble fertilizer according to the basis; 5 parts of ammonium nitrate; 5 parts of potassium chloride; 85 parts of potassium nitrate; 10 parts of ammonium dihydrogen phosphate; Potassium hydrogen; 0.9 parts of boric acid; 0.5 parts of zinc sulfate monohydrate; 2.5 parts of anhydrous magnesium sulfate; 0.5 parts of rare earth nitrate are mixed to obtain a water-soluble fertilizer.

Abstract

The invention provides a water-soluble fertilizer and a preparation method thereof. The water-soluble fertilizer comprises 70-95 parts of a nitrogen source, 5-80 parts of a phosphorus source, 15-95 parts of a potassium source, 0.1-10 parts of medium trace elements and 0.01-1 part of rare earth nitrate. The rare earth nitrate is produced by decomposing phosphorite through nitric acid with the mass percentage concentration of 55%-70% through dry ore dressing, is soluble in water and serves as a component of a compound fertilizer, the osmotic pressure of plant rhizomes can be improved, absorption of plants to nitrogen, phosphorus and potassium is promoted, the requirements of all elements are met for the plants, germination and growth of the plants are promoted, the content of soluble solids such as sugar, acid, vitamins and mineral substances of plants is further increased, so that the prepared water-soluble fertilizer has the beneficial effects of promoting germination and growth, increasing yield and improving quality, and meanwhile, no harmful pesticide residue exists.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a water-soluble fertilizer and a preparation method thereof. Background technique [0002] With the development of modern agriculture in our country, organic agriculture and green agriculture have become an important part of the development of modern agriculture. For a long time, people have not paid enough attention to the use of agricultural compound fertilizers. They think that as long as the seeds can germinate and the seedlings can grow, as the requirements for agriculture become higher and higher, the use of rough compound fertilizers in the past has also been severely restricted. challenge. [0003] With the continuous development of agriculture, there are more and more fertilizers compounded with multiple components. In order to improve soil physical properties and increase soil fertility, organic matter is generally added as a carbon source nutrient for microorganis...
