Embodiment 1

[0036] A humic acid water-soluble fertilizer with both insecticidal and bactericidal properties, the weight ratio of each component is: 9 parts of water-soluble humic acid, 23 parts of urea, 11 parts of potassium chloride, 7.5 parts of monoammonium phosphate, and Nuxychium seed extract 0.1 part, 0.15 part of licorice extract, 0.7 part of berberine, 0.6 part of blood water grass extract.

[0037] Wherein, the preparation technology of water-soluble humic acid comprises:

[0038] S1-1. Mix the humic acid-containing raw material with water at a weight ratio of 1:8. The humic acid-containing raw material is a mixture of weathered coal and lignite, wet ball mill it into a slurry, add sodium hydroxide solution until the pH of the slurry is 8.5, and import Precipitate in the sedimentation tank, filter after precipitation, and obtain primary filtrate and filter residue;

[0039] S1-2. The filter residue was frozen for 12 hours, quickly added 2 times the weight of the filter residue i...

Embodiment 2

[0056] Humic acid water-soluble fertilizer with both insecticidal and bactericidal functions, the weight ratio of each component is: 6 parts of water-soluble humic acid, 20 parts of urea, 10 parts of potassium chloride, 6 parts of monoammonium phosphate, and Nuxychium seed extract 0.05 parts, 0.1 parts of licorice extract, 0.3 parts of berberine, 0.2 parts of blood water grass extract.

[0057] Wherein, the preparation technology of water-soluble humic acid comprises:

[0058] S1-1. Mix the humic acid-containing raw material with water at a weight ratio of 1:12. The humic acid-containing raw material is weathered coal, wet ball mill it into a slurry, add potassium hydroxide solution until the pH of the slurry is 9.0, and import it into the sedimentation tank Carry out precipitation, filter after precipitation, obtain primary filtrate and filter residue;

[0059] S1-2. Freeze the filter residue for 12 hours, quickly add 3 times the weight of the filter residue in water at 50°C...

Embodiment 3

[0076] A humic acid water-soluble fertilizer with both insecticidal and bactericidal properties. The weight ratio of each component is: 10 parts of water-soluble humic acid, 25 parts of urea, 12 parts of potassium chloride, 8 parts of monoammonium phosphate, and Nuxychium seed extract 0.2 parts, 0.3 parts of licorice extract, 0.8 parts of berberine, 0.8 parts of blood water grass extract.

[0077] Wherein, the preparation technology of water-soluble humic acid comprises:

Abstract

The invention discloses a water-soluble humic acid fertilizer with effects of killing insects and bacteria and a preparation method of the fertilizer. The fertilizer comprises the following components in parts by weight: 6-10 parts of water-soluble humic acid, 20-25 parts of urea, 10-12 parts of potassium chloride, 6-8 parts of monoammonium phosphate, 0.05-0.2 part of nux vomica extract, 0.1-0.3 part of licorice extract, 0.3-0.8 part of berberine and 0.2-0.8 part of snowpoppy extract. The preparation method comprises the step of preparing potassium humate and Chinese herb extracts. The water-soluble humic acid fertilizer disclosed by the invention has the effects of bactericides, insecticides and fertilizers, only one-step drug delivery of peasant households is needed, the effects of killing bacteria and insects in advance are achieved, and comprehensive nutrient requirements can be provided for crops, so the drug and fertilizer utilization frequency is reduced, and the labor cost is effectively reduced.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a humic acid water-soluble fertilizer capable of killing insects and bacteria and a preparation method thereof. Background technique [0002] Water-soluble fertilizers are liquid or solid fertilizers that are dissolved or diluted in water and used for irrigation and fertilization, foliar fertilization, soilless cultivation, soaking seeds and dipping roots, etc. As a multi-component fertilizer, water-soluble fertilizer can be quickly dissolved in water, more easily absorbed by crops, and its absorption and utilization rate is relatively high, which can meet the nutritional needs of high-yield crops during the rapid growth period. Especially in facility agriculture, it is used in combination with micro-sprinkler irrigation, drip irrigation, etc., with water and fertilizer, to realize the integration of water and fertilizer, and to achieve the efficiency of saving water, fertilizer and la...
