Description

  The present invention relates to a method for producing fertilizer, and more particularly, to a method for producing fertilizer from fish waste.

  2. Description of the Related Art Conventionally, as a method for producing crop fertilizer from fish waste, a method of subjecting fish waste to fermentation treatment is known. Thus, when fertilizer is manufactured from fish, since this fertilizer contains the animal nutrient which fish has, it is known that this nutrient will promote the growth of crops.

  As a method for producing a fertilizer using this type of fish, for example, there is a method for producing an organic fertilizer of Patent Document 1. The fertilizer production method of the same document 1 pulverizes the whole or part of the fish obtained in the treatment process, residue, and internal organs, digests them with fish broth and stick water in a digestion tank, and further separates the digest into solid-liquid separation. Then, the fertilizer is obtained by transferring to an ultrafilter and filtering. This production method is intended to produce an organic fertilizer by taking out a fertilizer component from liquid solubles obtained from fish, crushed meat, internal organs and the like.

  Patent Document 2 is a method for producing fertilizer from seafood waste, and uses fishery waste such as fish internal organs and arabia as a material. The production method of the same document 2 includes a step of adding anaerobic bacteria and compounding materials to seafood waste, stirring and mixing, a step of draining the mixture, and putting the drained mixture into a fermentation tank for decomposition and moisture. The process of evaporating and the process of drying are going through, and it is going to shape | mold a powdery or granular fertilizer by this.

Japanese Patent Publication No. 6-62352 JP-A-10-114589

  However, the manufacturing method of the organic fertilizer of patent document 1 isolate | separates fish into the solid part which consists of whole or a part, residue, and internal organ part, and the liquid part which consists of boiled juice and stick water, and processes a solid part. After application, a process of mixing the solid part and the liquid part is required. For this reason, the work is troublesome, and it takes extra time and effort.

  On the other hand, since the fertilizer manufacturing method of Patent Document 2 also forms the fertilizer through a plurality of processes, the manufacturing process becomes complicated, and a large-scale facility for performing each process is required. Furthermore, this production method takes time because it causes the fishery waste to rot, ferment and compost.

  Moreover, the fertilizer obtained by these manufacturing methods has increased in volume and weight. Therefore, in addition to having a great deal of labor when fertilizing as a fertilizer, transportation and storage have become inconvenient. In addition, after applying these fertilizers, the effects of fertilizer may be lost or odors may be lost by decaying after adding water, and there is a possibility that it may be damaged by birds and beasts. Furthermore, this type of organic fertilizer is slow-acting, and it took a certain amount of time for the contained nutrients to flow out. Therefore, the function as a fertilizer may not be fully demonstrated.

  The present invention has been developed as a result of intensive studies in view of the above-described actual situation, and the object of the present invention is that it can produce fertilizer in a short time with simple equipment and production process, An object of the present invention is to provide a method for producing a fertilizer that significantly promotes the growth of crops and is easy to handle.

  In order to achieve the above object, the invention according to claim 1 is to produce fish waste made of fish meat, bone, built-in, etc. by burning with a suitable combustion means, and producing the ash as fertilizer. This is a method for producing fertilizer.

  The invention according to claim 2 is an ash product comprising a fish waste and a combustion-promoting product from a residue after combustion by mixing a combustion-promoting material such as burning wood, papers and oils with the fish waste and burning it. And an inevitable residue, and these are mixed and stirred to produce a fertilizer.

  The invention which concerns on Claim 3 is a manufacturing method of the fertilizer which mixed acidic liquids, such as a wood vinegar liquid and a bamboo vinegar liquid, in the fertilizer.

  According to the invention which concerns on Claim 1, a fertilizer can be manufactured in a short time with a simple installation and a manufacturing process, and the fertilizer after manufacture is a manufacturing method of the fertilizer which can accelerate | stimulate the growth of a crop remarkably. Moreover, the fertilizer after manufacture remarkably accelerates the growth of crops due to the components contained in the fish, and is easy to handle because of its small volume and extremely light weight. In addition, since fertilizer can be produced by using the discarded portion of fish, it is possible to reduce waste and contribute to ecology.

  According to the invention which concerns on Claim 2, it can produce | generate calcium, potassium, magnesium etc. which are useful as a fertilizer by ashing a fish waste with a combustion promotion thing, and cultivation of crops by fertilizing these It can be improved to a suitable soil.

  According to the third aspect of the invention, it is possible to cultivate crops by adjusting the pH value of the soil, and it is possible to cultivate vegetables, fruits and the like having high nutritional value and high sugar content.

Below, embodiment of the manufacturing method of the fertilizer in this invention is described in detail.
First, the material which becomes a fertilizer in the manufacturing method of the fertilizer of this invention is described. Fertilizer materials consist of fish waste and combustion accelerators. Moreover, an acidic liquid is mixed in the fertilizer after manufacture.
Fish waste consists of so-called fish arabic parts such as fish meat, bones such as the head and spine, internal organs, and fins of the tail. This fish waste may contain a part other than the waste, for example, an edible meat part, and the whole fish may be used as a fertilizer material.

  On the other hand, the combustion promoting material is made of, for example, burning wood, papers, oils and the like. The burned tree is preferably, for example, a dry deciduous tree in order to efficiently burn fish waste. The paper is preferably cardboard in order to improve the fire around when burned, and the oil is preferably kerosene in order to improve the fire around the paper.

  Moreover, an acidic liquid is mixed with a fertilizer as a soil improvement agent, for example, consists of a wood vinegar liquid, a bamboo vinegar liquid, etc. The charcoal vinegar is a liquid obtained by cooling smoke when making charcoal, and the bamboo vinegar is a liquid obtained by cooling smoke emitted when baking bamboo charcoal. These wood vinegar and bamboo vinegar are preferably adjusted to a pH of about 2.5 to 3.5, for example, and in this case have strongly acidic characteristics.

  When combusting the fertilizer, it may be carried out by an appropriate combustion means. In this embodiment, an incinerator is used as the combustion means, and a sieve is used as the equipment after combustion. An appropriate incinerator may be used, but it is preferable that the incinerator has a volume that facilitates combustion of fish waste and combustion promoting materials and has excellent ventilation. Furthermore, it is desirable that this incinerator has a function of preventing generation of dioxins during combustion. In addition, a sieve that can select a portion used as fertilizer after incineration and other portions is used.

Then, the manufacturing method of the fertilizer in this invention is demonstrated. In FIG. 1, an example of the manufacturing method of the fertilizer of this invention is shown.
First, before burning the fertilizer, a burning tree for increasing the thermal power is assembled in the incinerator. The method of assembling the burning trees at this time is an appropriate state in consideration of ventilation as in the case of normal burning. In addition, fish waste is placed on top of this, and cardboard is placed in an appropriate state to improve the initial fire around and inside the fish waste, and further burned if necessary. Install trees (install combustion-promoting materials).

  In this state, a cardboard soaked with a small amount of kerosene is ignited, and this is used as a seed fire in an incinerator to burn fish waste. When fish is burned, proteins, lipids, and carbohydrates burn and they become ashed. This ash contains various mineral components such as calcium phosphate, potassium, and magnesium.

  Fish waste after combustion is screened through a sieve to remove the unburned bone and obvious burned wood from the residue after combustion, and the ash is composed of fish waste and combustion accelerators. Take out with inevitable residues. Furthermore, the fertilizer for fertilization is manufactured by mixing and stirring these. This fertilizer should be stored in a suitable container or the like so as not to get wet with water such as rain. For example, the fertilizer may be stored in a compact state by being compressed in a suitable bag. .

In this embodiment, the fish waste is added with a combustion accelerator and burned. However, for example, it is possible to produce fertilizer using only fish waste as a material by using equipment such as a large incinerator. is there.
Moreover, when fertilizing this fertilizer, an acidic liquid is mixed into the fertilizer as necessary as described later.

Next, the effect | action in the said embodiment of the manufacturing method of the fertilizer of this invention is demonstrated.
The method for producing a fertilizer of the present invention is a simple production process because the fish waste is burned and ashed by an appropriate combustion means as it is without being separated for each waste part, and the ash is produced as a fertilizer. This fertilizer can be manufactured in a short time. Moreover, it can manufacture with a small-scale installation.

  The fertilizer after production is small in volume due to evaporation of moisture, and is very lightweight, so it is easy to handle during fertilization, and crops can be cultivated with a small amount of fertilization, so the work time during fertilization can be shortened It is also easy to transport and store. Moreover, since the spoilage is prevented after fertilization, the effect of promoting cultivation can be maintained, and malodor can be suppressed. Furthermore, damage caused by birds and beasts can be suppressed.

  Furthermore, since this fertilizer is an ash containing various mineral components such as calcium phosphate, potassium and magnesium, which are animal nutrients, these mineral components can act on the crops and promote growth. At this time, nutrients easily flow out due to the characteristics of the ash, and immediate effect is exhibited. Furthermore, depending on the soil quality, supply dietary fiber, etc. as necessary to improve moisture retention, repeat fertilization, and other nutrients (for example, bamboo treated with a planting machine) It may be added in combination, and in this case, it is possible to further promote growth.

  At this time, it is a problem of manure such as human dung and dog dung that has been generally used as a fertilizer to improve the quality of crops. 1. It is difficult to continuously harvest good fruits (causes fertilizer running out). 2. An enormous amount of additional fertilizer is required and a great deal of labor is required. 3. The soil balance is significantly disrupted by residual fertilizers from repeated topdressing. It can also solve problems such as a significant drop in quality when it is continuously produced. That is, the fertilizer manufactured by the manufacturing method of the fertilizer of this invention is 1. 1. Good fruits can be continuously harvested with a small amount of fertilizer while reducing the amount of fertilizer used. 2. Less need for topdressing; 3. Residual fertilizer can be suppressed and soil balance can be maintained. There is an advantage that crops can be continuously cropped and the crops can be cultivated with high quality.

  Furthermore, at the time of fertilization, an acidic liquid composed of wood vinegar or bamboo vinegar can be mixed in the fertilizer. In this case, the acidic liquid having strong acidity can suppress the inclination of the soil to alkaline due to the fertilizer being alkaline, and the soil can be improved from weakly acidic to neutral. As a result, the growth of the crops such as the growth of microorganisms existing in the soil and the activation thereof, which facilitates the emergence of crops and the improvement of rooting, is promoted.

Next, the Example in the case of manufacturing a fertilizer with the manufacturing method of the fertilizer of this invention is shown below.
In this example, tuna fish ara (head / tail and bone periphery) as fish waste, and burned wood made of dried deciduous trees, corrugated cardboard, and kerosene were used according to the amounts shown in Table 1. In addition, as an incinerator for combusting these, “Moki Seisaku Takifire Incinerator MP200L” was used.

  Under the above conditions, fish waste was burned to produce a fertilizer. At this time, since the fish arabe contained a lot of moisture and was difficult to burn, it was burned in two steps and ashed. This burning operation was completed after approximately 2 hours.

  Next, the combusted material is passed through a sieve, and it can be clearly judged that the fish ara (fish waste) has been ashed, ash, cardboard, and burned tree ash are mixed, clearly burned wood It can be divided into those that can be judged to be charred and those that can be clearly judged as fish ara bones. Table 2 shows the weight of the residue after combustion. Of these, a fish that can be clearly judged to have been ashed and a mixture of ash, cardboard, and burnt wood ash were taken out and mixed and stirred to obtain 910 g of fertilizer. At this time, due to the condition of combustion and the skill of the worker, a part of the fertilizer was mixed with a carbonized substance without ashing, but this carbonized substance was 20% of the whole fertilizer (182 g). ) Since it was the following minute amount, it was granulated by pulverization. Thereafter, the fertilizer was packed into a pineal bag or the like having a high sealing property and stored in a container made of a drum can so as to be stored.

Subsequently, an operation example when fertilizing the fertilizer obtained by the above-described embodiment and the growth situation of the crop after fertilization will be described.
The fertilizer application time was the same as when applying normal chemical fertilizer. Further, the amount of fertilizer varies depending on the crops to be cultivated, but is about 100 to 150 kg per one (about 991.7 m ² ). Furthermore, in some cases, fertilization was performed by increasing the amount of fertilization up to about 450 kg in order to improve the quality. Moreover, the fertilizer obtained by the said Example was fertilized and the watering was implemented with respect to the general cultivation method with a short cultivation period which used liquid manure as additional fertilization until then.

  Moreover, in any case, during cultivation, the pH value of the soil was appropriately measured, and an acidic liquid such as a wood vinegar or bamboo vinegar was mixed into the soil as needed. Furthermore, in order to improve drainage, an appropriate fertilizer other than the fertilizer obtained by the production method of the present invention was applied to adjust the fertilizer balance. The crops were cultivated under the above conditions, and the following results were obtained for these crops.

Koji, radish, Chinese cabbage, and lettuce increased in umami, richness, and sweetness, had a lot of freshness (water content), improved taste and mouthfeel, and gave a juicy texture. Furthermore, when fertilization of about 450 kg per koji was performed on the koji, the sweetness and umami became stronger, the taste deepened, and freshness like fruit was obtained.
Further, by repeating these cultivations and sowing excellent seeds again, further quality improvement was achieved after a few years.
Ochiai potatoes have a stronger taste and richness and improved taste. In addition, potatoes are originally small cocoons, but have become large by using ash fertilizer.
The taro has a distinctive odor and has a refined and deep taste.
As for the Momotaro tomato, the vigor increased, the taste and richness improved, and the sugar content also increased.
In addition, cucumbers, eggplants, tomatoes, etc. were able to be continuously cropped and the quality was improved.

On the other hand, with regard to fruit trees, plums, peaches, grapes, kiwis, and apples have less umami and other rich components, resulting in stronger umami and richness, and increased sugar content.
Here, as an example, actual measured values of peach sugar content are shown in the following table. As shown in this table, all sampled peaches had high sugar content.

It is the flowchart which showed an example of the manufacturing method of the fertilizer in this invention.
