Description
Technical Field
The invention relates to a special fertilizer for radish and a preparation method thereof, belonging to the field of fertilizer preparation.
Background
The brewing of beer takes grains as main production raw materials, and after a series of fermentation processes, beer wastes are generated. The beer waste contains microorganisms and abundant nutrients such as protein, cellulose, starch and the like. The production and sales volume of beer in China is the first in the world for years, the beer waste accounts for about one fourth of the production volume of the beer, the beer waste is increased year by year along with the rapid development of the beer industry, the waste is not reasonably utilized, and serious consequences are certainly generated on the environmental development and the industrial development.
In order to fully utilize the waste beer, people begin to find a method for utilizing the waste beer. At present, beer wastes are more commonly applied to the fields of food, feed and plant fertilizer.
In the field of using beer fermentation waste in plant fertilizer, there are two common methods of using the beer fermentation waste.
The first method comprises the following steps: because the beer fermentation waste contains various nutrient substances, the beer fermentation waste can be directly mixed with major elements and trace elements required by various plants to prepare the plant fertilizer containing the beer fermentation waste. For example, CN108840769A "a flower fertilizer" discloses a flower fertilizer: mixing 7-15 parts by weight of ammonium nitrate, 5-10 parts by weight of calcium phosphate, 5-10 parts by weight of potassium chloride, 10-20 parts by weight of rapeseed cakes, 8-16 parts by weight of brewer's grains and 4-12 parts by weight of straw powder together to prepare the flower fertilizer; CN109665887A organic fertilizer for white radish planting for increasing soil fertility discloses a fertilizer, which is prepared by mixing the following components in parts by weight: 40-50 parts of poultry manure, 15-20 parts of earthworm manure, 7-9 parts of urea, 5-8 parts of quick lime, 5-6 parts of egg shells, 2-3 parts of brewer's grains, 2-3 parts of ammonium molybdate, 1-2 parts of rice husk powder, 1-2 parts of potassium phosphate, 1-2 parts of zeolite powder, 0.5-1 part of food gum, 0.5-1 part of sodium sulfate, 0.5-1 part of edible fungus residues, 0.5-1 part of wood ash and the balance of water.
However, after the fertilizer prepared by the method is applied, the utilization rate of macroelements and medium trace elements in the fertilizer is low, and various nutrient elements cannot be effectively utilized.
And the second method comprises the following steps: because the beer fermentation waste contains a large amount of protein, the amino acid obtained after the protein degradation not only has unique physiological action on plants, but also can chelate trace elements, thereby improving the utilization rate of the trace elements. Therefore, the prior art generally degrades the beer fermentation waste into amino acid (including acidolysis, enzymolysis, etc.), and then applies the amino acid to various plant fertilizers. For example, CN1312238A "new process for producing amino acid chelated fertilizer" discloses a method for producing amino acid chelated fertilizer: the method mainly comprises the steps of carrying out enzymolysis on the beer mud to obtain amino acid liquid, and then chelating the amino acid liquid with mineral elements to obtain the amino acid chelated fertilizer.
However, in the second method, the beer fermentation waste needs to be degraded into amino acid, and the operation is complex; the degradation of protein usually needs solid-liquid separation, the waste liquid is utilized to prepare amino acid, and the beer fermentation residue can not be well utilized; in addition, the cost of enzymes used for protein degradation is high, resulting in an increase in cost.
