Embodiment example

[0028] Select 90 parts of fulvic acid solution, 20 parts of lactic acid bacteria, 20 parts of Paenibacillus megaterium, 10 parts of Tenebrio molitor feces extract, 2 parts of EDTA, 10 parts of alginic acid, 3 parts of ammonium molybdate, 20 parts of amino acids, 0.2 parts of manganese sulfate, 1 part of boric acid, 0.2 part of phosphoric acid solution.

[0029] Adopt above material composition, preparation method comprises the following steps:

[0030] 1) Fermentation: Mix the fulvic acid solution and Tenebrio molitor excrement extract in a ratio of 9:1 by weight, stir and mix well to make a mixed material, insert lactic acid bacteria into the mixed material, and put it into the industrial Fermentation tank, and stir evenly, start aerobic fermentation, after fermentation, it is detected that the content of fulvic acid in the fermented product is ≥ 30%, and the content of organic matter is ≥ 60%;

[0031] 2) Chelation: pump alginic acid, ammonium molybdate, amino acid, mangane...

Abstract

The invention belongs to the field of biological organic fertilizer and organic fertilizer, and more specifically relates to a method used for preparing biological organic fertilizer and organic fertilizer through fulvic acid spraying granulation. According to the method, the adopted fulvic acid is biomass fulvic acid classified based on GB/T 35112-2017; industrial and agricultural production sideproducts are taken as the main raw materials, microbial fermentation technology is adopted to prepare the fulvic acid; the fulvic acid is soluble in diluted aqueous alkali, and acid and water, a diluted solution of the fulvic acid is yellow or brown-yellow (fulvic acid solution prepared through fermentation of sugar industry by product molasses alcohol concentrate, yeast concentrate, and other agricultural wastes); and then chelating, granulation, drying, cooling, and sieving are carried out so as to obtain the finished products. According to the method, resource utilization of production waste is realized; the prepared product is comprehensive in nutrients, is capable of shortening crop growth period, increasing yield, improving crop quality, and reducing using of fertilizers and pesticides; microbial fermentation is adopted, so that large molecules are converted into small molecules, all the components are soluble in water, and it is beneficial for adsorption by crops.

Description

technical field [0001] The invention belongs to the field of bio-organic fertilizers and organic fertilizers, relates to bio-organic fertilizers and organic fertilizers, and in particular relates to a method for preparing bio-organic fertilizers and organic fertilizers by spraying and granulating fulvic acid. Background technique [0002] At present, the production process of granular organic fertilizer mainly includes roller granulation, extrusion granulation, etc. The biggest problem is solid granulation, which is random, causes dust pollution during the production process, cannot be dissolved in water, and is not conducive to crop absorption. The spray granulation process we invented has rich and cheap material sources, low production cost, low energy consumption, full water solubility, uniform particle size, smooth and beautiful particles, fragrant smell, fast crop absorption, obvious yield increase effect, and effective supply of soil organic matter. , Improve the soil ...
