Full-water-soluble organic-inorganic compound fertilizer and preparation method thereof

Abstract

The invention discloses a full-water-soluble organic-inorganic compound fertilizer, which comprises potassium fulvate, ammonium sulfate, monopotassium phosphate, anhydrous magnesium sulfate, metalloproteinase and Jikang enzyme. The Jikang enzyme is prepared by the following steps: uniformly stirring and mixing 100 parts of plant acid, 600 parts of amino acid and 5 parts of an amino acid surfactant; adding 100 parts of mineral source fulvic acid and 150 parts of humic acid, fully stirring and uniformly mixing all the components, adding the mixture into a fermentation tank, inoculating a microbial agent for cultivation for 18 hours, and finally adding 15 parts of chitosan and 10 parts of subtilisin, and uniformly mixing all the components for obtaining the Jikang enzyme. The invention also discloses a preparation method of the fertilizer, which comprises the following steps: preparing metalloproteinase, and mixing the raw materials. The compound fertilizer is a biological, organic and inorganic combined fertilizer, organic components (fulvic acid) in the fertilizer form colloidal substances in soil, the formation of a soil aggregate structure can be effectively promoted, and the water, fertilizer, gas and heat conditions of the soil are coordinated.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, in particular to a fully water-soluble organic-inorganic compound fertilizer and a preparation method thereof. Background technique [0002] At present, the main fertilizers supplied and used in China are inorganic compound fertilizers. Long-term use of inorganic compound fertilizers will destroy the soil aggregate structure, cause soil compaction, and seriously affect the yield and quality of crops. Organic-inorganic compound fertilizer refers to a compound fertilizer containing organic matter and inorganic nutrients. It has high organic matter content and long-lasting fertilizer effect. It can improve crop resistance, improve soil physical and chemical properties, improve fertilizer utilization rate, improve quality and increase production. Therefore, organic-inorganic compound fertilizers have gradually received attention. With the development of agriculture, large-scale planting has be...

AI Technical Summary

Problems solved by technology

Therefore, organic-inorganic compound fertilizers have gradually received attention. With the development of agriculture, large-scale planting has become a trend, and irrigation equipment has gradually entered the planting base. This has higher and higher requirements for organic-inorganic compound fertilizers. The organic raw materials of compound fertilizers (such as rapeseed meal, chicken manure, etc.) have poor water solubility, resulting in low water solubility of the finished organic-inorganic compound fertilizer, which cannot meet the requirements of current agricultural irrigation facilities
