A preparation method of a yeast coated fertilizer comprises the following steps: weighing the fertilizer core according to the raw material proportion, and uniformly mixing and stirring to form a mixture; the obtained mixture is sent into a granulator and is pelletized and granulated in the granulator; after granulation is finished, sending the mixture into a dryer for drying and cooling to obtain a fertilizer core; mixing yeast with nutrient solution to form slurry; and spraying the obtained slurry to ensure that the yeast is uniformly adhered to the surface of the fertilizer core particles, thereby obtaining the yeast coated fertilizer. After long-term application of the yeast coated fertilizer, the soil structure can be effectively improved, soil organic matters are increased, the effect of soil cultivation and soil fertilization is achieved, the safety, the stable yield and the high yield of crops are guaranteed, and the quality of the crops is improved; the fertilizer consumption can be reduced by 20-30%, and the purposes of reducing weight, improving efficiency and reducing soil pollution are achieved.
Description
Technical Field
The invention relates to the technical field of fertilizers, in particular to a yeast coated fertilizer and a preparation method thereof.
Background
The coated fertilizer, also called coated fertilizer or wrapped fertilizer, is made by spraying a thin layer material on the surface of the fertilizer by a physical method. The coating materials used are various, and mainly include sulfur, high molecular polymers, resins, paraffin, asphalt, and the like. The film-forming substances are wrapped on the surface of the water-soluble granular fertilizer, so that the fertilizer is prevented from being directly contacted with soil and crop roots, moisture enters the film to dissolve nutrients, the osmotic pressure is increased, the nutrients are promoted to diffuse to the soil solution through the film or are slowly released outwards through small holes of the film and are continuously absorbed and utilized by crops, the leaching loss of the soluble nutrients, the volatilization loss of ammonia, the fixation of phosphorus and the like are reduced, and the utilization rate of the fertilizer is improved.
The core of soil fertilization is soil cultivation, and the core of soil cultivation is to increase organic matters and improve the soil structure. The current situation of the production fertilizer is that the fertilizer depends on chemical fertilizer blindly and the fertilizer consumption is too large, which generally causes soil barrenness and pollution. The existing coated fertilizer has the defects that the release efficiency of the fertilizer is limited to be controlled, the release rate is difficult to control, and organic matters and soil structures of soil cannot be changed. In order to respond to the national call, reduce the fertilizer dosage, encourage the use of organic fertilizer, improve the soil ecological environment and improve the crop quality, a fertilizer which can reduce the fertilizer dosage and ensure the improved soil and the enhanced fertility effect is urgently needed.
Disclosure of Invention
The invention aims to overcome the technical defects and provides the yeast coated fertilizer and the preparation method thereof, which have the advantages of weight reduction, efficiency improvement, soil pollution reduction, soil ecological environment improvement and crop quality improvement.
In order to achieve the purpose of the invention, the invention adopts the technical scheme that: a yeast coated fertilizer comprises a fertilizer core and a coating coated outside the fertilizer core, wherein the coating is made of yeast of a fermentation substance.
Further, the fertilizer core is any one of compound fertilizer, mixed fertilizer, organic fertilizer and organic-inorganic compound fertilizer.
Further, the yeast is a biological bacterial liquid.
Further, the preparation method of the yeast coated fertilizer comprises the following steps:
step 1: weighing the fertilizer core according to the raw material proportion, and uniformly mixing and stirring to form a mixture;
step 2: feeding the mixture obtained in the step 1 into a granulator, and carrying out granulation in the granulator;
and step 3: feeding the particles obtained in the step (2) into a dryer for drying and cooling to obtain a fertilizer core;
and 4, step 4: mixing yeast with nutrient solution to form slurry;
and 5: and (4) spraying the slurry obtained in the step (4) to ensure that the yeast is uniformly adhered to the surface of the fertilizer core particles, namely the yeast coated fertilizer.
The invention has the beneficial effects that: the fertilizer coated by the yeast does not influence the physicochemical properties of the fertilizer, and the yeast coated fertilizer can effectively improve the soil structure, increase the organic matters of the soil, achieve the effect of soil cultivation and soil fertility, ensure the safety, stable yield and high yield of crops and improve the quality of the crops after being applied for a long time; the fertilizer consumption can be reduced by 20-30%, and the purposes of reducing weight, improving efficiency and reducing soil pollution are achieved.
Detailed Description
In order to make the content of the present invention more clearly understood, the technical solutions in the embodiments of the present invention are clearly and completely described below.
A yeast coated fertilizer comprises a fertilizer core and a coating coated outside the fertilizer core, wherein the coating is made of yeast of a fermentation substance. The fertilizer core is any one of compound fertilizer, mixed fertilizer, organic fertilizer and organic-inorganic compound fertilizer. The yeast is biological bacteria liquid.
A preparation method of a yeast coated fertilizer comprises the following steps:
step 1: weighing the fertilizer core according to the raw material proportion, and uniformly mixing and stirring to form a mixture;
step 2: feeding the mixture obtained in the step 1 into a granulator, and carrying out granulation in the granulator;
and step 3: feeding the particles obtained in the step (2) into a dryer for drying and cooling to obtain a fertilizer core;
and 4, step 4: mixing yeast with nutrient solution to form slurry;
and 5: and (4) spraying the slurry obtained in the step (4) to ensure that the yeast is uniformly adhered to the surface of the fertilizer core particles, namely the yeast coated fertilizer.
The fertilizer coated by the yeast does not influence the physicochemical properties of the fertilizer, and after the yeast is applied to the soil, the yeast absorbs moisture in the soil and dissolves in the soil, so that a large amount of residual plant bodies in the soil can be promoted to be decomposed, soil organic matters can be increased, and meanwhile, the yeast can react in the soil to generate a large amount of carbon dioxide gas to flow so as to promote soil loosening and improve soil air permeability. The utilization rate of the fertilizer in the fertilizer core wrapped by the yeast is higher than that of the fertilizer without wrapping the yeast, the loss of fertilizer nutrients is reduced, the utilization rate of the fertilizer is obviously improved, soil hardening caused by excessive fertilization is avoided, environmental pollution and even poisoning of people and livestock caused by excessive fertilization are effectively prevented, nutrient supply is coordinated, balanced fertilization is realized, and high quality and high yield are achieved.
The present invention and the embodiments thereof have been described above, but the description is not limited to the embodiments, but only one of the embodiments of the present invention, and the actual embodiments are not limited thereto. In conclusion, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
