Description
Technical Field
The present invention relates to a method for producing an organic fertilizer composition, and more particularly, to a method for producing an organic fertilizer composition having an odor reducing function, which contains a liquid deodorant and a solid byproduct extracted from Peat (Peat moss) as active ingredients, and which uses livestock manure, agricultural byproducts, and the like.
Background
Peat is obtained by decomposing aquatic plants and sphagnum in oxygen-deficient soil for a long time in a cold region with high precipitation and low average annual temperature, i.e. a frozen soil zone. Peat is not only fully humated (Humification) but also rich in organic matter content, and has many natural physiologically active substances, high cation replacement amount and various mineral components, so that peat is widely applied to the fields of agriculture, animal husbandry, flowers and the like.
Nowadays, researches and applications of peat are limited in the fields of organic matter supply in agriculture and flowers, and in the fields of livestock raising and environment, and the case of applying liquid deodorizers and solid byproducts extracted by fermenting peat to the environment is absolutely not the only case.
Disclosure of Invention
The invention aims to provide an organic fertilizer composition, which takes peat fermentation extract-liquid deodorant and solid by-products as effective components, and not only kills pathogenic harmful microorganisms, parasites and the like existing in livestock manure, agricultural by-products and the like under an aerobic fermentation process carried out at a higher temperature of 50-70 ℃; but also decompose harmful components, thereby preventing growth disorder of crops and reducing odor.
Specifically, the use of the peat fermentation extract and the solid by-products can reduce and reuse the odor of livestock manure produced in animal husbandry, reduce the odor produced in the work site, and reduce the odor produced in the living environment.
In order to achieve the above object, an organic fertilizer with reduced odor is provided, which uses peat fermentation extract-liquid deodorant and solid by-product, rice bran as effective ingredients, and livestock manure, agricultural by-products, etc.
The invention also provides a composition of the livestock manure odor reducing agent, which takes peat fermentation extract-liquid deodorant and solid by-product, rice bran as effective components.
Furthermore, the invention provides a composition for improving fermentation efficiency during fermentation of agricultural byproducts by taking peat fermentation extract-liquid deodorant and solid byproducts, rice bran as effective components.
Peat is involved in decomposing organic matters in a natural accumulation process of hundreds or thousands of years in a cold wetland of a frozen soil zone, and in order to overcome an extremely cold environment, pressure hormones and the like in the extremely cold environment are generated and are repeatedly oxidized, reduced, overlapped and polycondensed. In this process, the pH of the peat is changed to a strong acidity of 3.0 to 4.0, and the conditions for survival are deteriorated. The microorganisms are thus dormant in the peat in a dormant state for periods of hundreds to thousands of years. In order to revive microorganisms which are dormant in a strongly acidic environment (pH 3.0 to 4.0), a strongly basic substance, namely calcium hydroxide (Ca (OH)), is added in an amount of 2 to 3% by weight of peat to activate the microorganisms; adding a weakly alkaline fermentation catalyst (sodium bicarbonate (NaHCO)) accounting for 3-5% of the weight of the peat to increase the pH value to 12.0 so as to enable extremely cold microorganisms in dormancy to move; and adjusting the required temperature, moisture, humidity and other fermentation conditions to produce the extreme cold environment stress hormone, namely the natural physiologically active substance. Wherein, the natural physiological active substance is a liquid deodorant and a peat solid byproduct.
In addition, the liquid deodorant is added to the livestock urine (liquid manure) in a proportion of 0.01 to 0.02% by weight of the urine (liquid manure). And an injector (ejector) having an injection pressure is used to rapidly inject urine (liquid manure) to form a circulation so that the livestock urine (liquid manure) reaches a sufficient condition for aerobic fermentation, thereby fermenting the livestock urine (liquid manure) and removing odor.
In addition, 75-85 wt% of livestock manure (compost) produced in animal husbandry, 10-15 wt% of solid by-products, and 5-10 wt% of rice bran are put in and mixed. In the fermentation process, the liquid deodorant is sprayed according to the weight ratio of 0.03-0.05 percent, and the mixture is stirred in a stirring type fermentation device under the sufficient condition of aerobic fermentation, so that the fermentation of the livestock manure (compost) is achieved, the odor is removed, and the organic compost containing a proper amount of fertilizer components is manufactured.
In addition, 70-85% (weight ratio) of finely crushed materials such as corn stalks, rice straws, wheat straws and the like produced in agriculture, 10-20% (weight ratio) of peat solid byproducts and 5-10% (weight ratio) of rice bran are put into the fermentation tank and mixed, and the liquid deodorant is sprayed according to 0.05-0.1% (weight ratio) in the fermentation process. Stirring in a stirring type fermentation device under sufficient conditions of aerobic fermentation, thereby removing odor generated in the fermentation process of corn stalks, rice straws, wheat straws and the like as agricultural and sideline products and manufacturing organic compost rich in organic matters.
Further, the organic compost containing a suitable amount of fertilizer components produced by the fermentation of the livestock excrements (compost) and the removal of the odor is added at a weight ratio of 70 to 80%, and the organic compost rich in organic substances produced by fermenting corn stalks, rice straws, wheat straws or the like as agricultural byproducts is added at a weight ratio of 20 to 30% and mixed, and stirred in a stirring type fermentation apparatus. And a manufacturing process for spraying liquid manure with the total weight of 3-5% to provide water and improve fermentation efficiency, thereby manufacturing high-quality compost.
The invention takes peat fermentation extract and solid by-product as effective components, not only fermenting livestock manure produced in livestock raising and reducing odor, thereby being capable of reusing the livestock manure in the form of liquid fertilizer and organic fertilizer, but also reusing the by-products produced in the production of agricultural products, such as corn stalk, straw, wheat stalk, and the like, as the organic fertilizer, thereby improving the soil environment by providing organic fertilizer composition for wasteland which is excessively used by chemical fertilizer, further improving crop parameters and improving the quality of crops.

Detailed Description
The invention relates to an organic fertilizer composition with reduced odor, which takes liquid extract and solid by-product with reduced odor as effective components and adopts livestock manure, agricultural by-product and the like in Peat (Peat moss) fermentation extract, wherein the liquid extract with reduced odor in Peat (Peat moss) fermentation extract is mixed with the solid by-product, the livestock manure and the agricultural by-product, and the organic fertilizer with reduced odor is determined under sufficient conditions required by fermentation at proper temperature, moisture, humidity and the like, thereby determining that the liquid extract and the solid by-product without Peat fermentation can be used for reducing the odor.
The artificial composting process is a process in which a stable substance is obtained by humification in a relatively short time under limited conditions, and thus the C/N (carbon to nitrogen ratio), PH, aeration, moisture content, temperature, particle size, and the like are essential for maintaining the activity of microorganisms in an optimum state. The most suitable C/N ratio is 20 to 30 as a raw material of compost, the decomposition of organic matter in the composting process is the highest value of activity when the pH value is neutral or weakly alkaline, and the air supplied in the composting process plays roles of aerobic metabolism of microorganisms, temperature regulation, moisture removal, CO2 and other gases. The moisture content is an essential element for controlling the composting rate, the initial moisture content is suitably 50 to 65%, the decomposition rate is reduced when the moisture content is less than 40%, the activity of aerobic microorganisms is suppressed when the moisture content exceeds 65%, the composting process is converted to an anaerobic state, and the possibility of generating offensive odor is generated. FIG. 1 is a schematic diagram showing the efficiency of decomposing organic matter in the composting process. The temperature range with highest organic matter decomposition efficiency in the composting process is 45-65 ℃ as shown in figure 1. Although the killing of pathogenic bacteria and weeds is also important, this is the temperature range necessary for the composting process.
Livestock manure (livestock excrements) has been used for a long time as a nutrient supply source which is very important in crop growth, and is recently recognized as a soil organic matter supply and a soil conditioner. The composting application of the livestock manure can be used as a resource circulation and a substitute resource of green agriculture, and the development effect of the composting application also plays an important role in the development of sustainable agriculture.
