Description

Technical Field

[0001] The invention belongs to the field of chemical fertilizers, and in particular relates to a full-nutrient liquid fertilizer containing wood vinegar amino acids and a preparation method thereof. Background Art

[0002] Fertilizer refers to a substance that can provide nutrients needed for crop growth and development, improve soil properties, and increase crop yield and quality. It is an important means of production in agricultural production.

[0003] Existing fertilizers are mainly solid fertilizers. Although they are widely used in manual spreading, furrow application, hole application and other operations, they are not conducive to modern agricultural spraying, spreading, drip irrigation and other operations, especially the drone spraying operations that have emerged in recent years. There are obvious limitations, that is, the overall efficiency is poor. It is based on this that the technical solution of the present invention is proposed. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a full-nutrient liquid fertilizer containing wood vinegar amino acids, which includes the following raw materials: biomass acetic acid liquid (wood vinegar liquid), urea, diammonium phosphate, potassium sulfate, magnesium sulfate, zinc sulfate, ferrous sulfate, manganese sulfate, copper sulfate, calcium sulfate, borax, polyaspartic acid liquid, polyvinyl alcohol, and ethylenediaminetetraacetic acid.

[0005] In order to facilitate understanding of the present invention, the raw materials of the present invention are described:

[0006] Biomass acetic acid liquid: obtained by collecting gas condensation from wood shavings during the industrial production of charcoal.

[0007] Urea: Urea is a high-concentration nitrogen fertilizer and a neutral quick-acting fertilizer. It can also be used to produce a variety of compound fertilizers. It does not leave any harmful substances in the soil and has no adverse effects if applied for a long time.

[0008] Diammonium phosphate: Diammonium phosphate is a compound fertilizer containing two nutrients, nitrogen and phosphorus. It is a high-concentration quick-acting fertilizer with less solids after dissolution. It is suitable for various crops and soils, especially for crops that prefer nitrogen and need phosphorus. It can be used as basal fertilizer or topdressing. Applying it on acidic soil can reduce the fixation of phosphorus by iron and aluminum, so that the effectiveness of phosphorus remains high. It is recommended to apply it deeply.

[0009] Potassium sulfate: A commonly used potash fertilizer with a potassium oxide content of about 50%.

[0010] Magnesium sulfate: Magnesium sulfate is used to improve magnesium-deficient soil. Magnesium is a basic element of chlorophyll molecules.

[0011] Zinc sulfate: It can be used to prevent diseases in fruit tree nurseries. It is also a commonly used fertilizer to supplement zinc trace element fertilizer for crops. It can be used as base fertilizer, foliar fertilizer, etc.

[0012] Ferrous sulfate: regulates soil pH, promotes chlorophyll formation (also known as iron fertilizer), can prevent and treat chlorosis of flowers and trees caused by iron deficiency, and is an indispensable element for acid-loving flowers and trees, especially cycads.

[0013] Manganese sulfate: can promote crop growth and increase yield.

[0014] Copper sulfate: It is effective in preventing and controlling a variety of plant diseases, such as those caused by fungi and bacteria.

[0015] Calcium sulfate: Calcium sulfate can be used as a fertilizer in agriculture to reduce soil alkalinity and improve soil properties.

[0016] Borax: It has the functions of promoting growth and development, increasing yield, improving quality, enhancing stress resistance, and preventing and controlling diseases and pests.

[0017] Polyaspartic acid liquid: Polyaspartic acid is a water-soluble bionic polymer that can be used as a plant nutrient absorption enhancer. It can effectively promote the absorption of nutrients by plants, reduce agricultural production costs, increase the yield and quality of crops, and reduce surface water and groundwater pollution caused by fertilizer and pesticide loss. It can be used in conjunction with pesticides and fertilizers to improve the utilization rate of pesticides and fertilizers and enhance the competitiveness of fertilizers.

[0018] Polyvinyl alcohol and ethylenediaminetetraacetic acid: used as thickener and complexing agent respectively to prevent system stratification and maintain stability.
