Description

  The present invention relates to a plant cultivation material for growing a plant. More particularly, the present invention relates to a material that can be used as a substitute for soil for cultivating plants. The present invention also relates to a method for producing dried okara suitable for use in the plant cultivation material.

  Conventionally, the use of waste organic materials as plant fertilizers has been performed, but an example of using okara obtained by the production process of tofu as one of such waste organic materials is, for example, Patent Document 1, It is proposed in Patent Document 2 and the like.

  Okara (hydrous okara) obtained in the process of tofu production contains a lot of water and is susceptible to spoilage, so that it can be easily stored and transported. Thus, the dried okara is obtained and used for various purposes. For example, Patent Document 3 proposes a technique for obtaining dried okara from hydrous okara by placing the okara at a relatively high temperature using a heating drum or the like.

On the other hand, in recent years, greening of building walls, top surfaces such as roofs and rooftops, and side surfaces of ridges has been carried out in order to mitigate heat island phenomena in urban areas, purify the atmosphere, and protect the environment. . As an example of such a greening structure, there is one described in Patent Document 4, for example.
Japanese Patent Laid-Open No. 2001-120054 JP 2001-199780 A JP 2005-21770 A JP 2004-248550 A

Here, since the greening structure as described in Patent Document 4 uses a cultivating base made of a lightweight material using foam or the like, it is relatively expensive and energy is consumed in the production process. There is a fact that the burden on the environment is relatively large, such as consumption and discharge of harmful substances. In addition, when it is used and discarded, it becomes industrial waste and the like, which also has a heavy environmental impact.
Therefore, a plant cultivation material that is easy and inexpensive to manufacture and has a low environmental burden is desired.

  In recent years, the demands of users have also diversified, such as home gardens, building verandas, rooftops, walls, fences, etc. for various purposes (aesthetics, decoration, blindfolds, awnings, etc.) or as a substitute for hedges, etc. Planting materials are planted as a single unit (planting unit), and various plants (small trees, flowers, grass, moss, sedum, fruits, etc.) are used for planting. In addition, there is a demand for replacing the planting unit every season.

  Furthermore, for example, a planting unit may be used as an advertising medium in an object or an exhibition (for example, a flower letter is used as an information transmission medium) or for the creation of an amenity space. It is done.

  Therefore, the planting unit is also required to have a high degree of design freedom so as to meet such diversified demands. In addition, it is required to be easy to handle, including loading and unloading.

  Further, conventionally, in order to meet the demand for obtaining dried okara from hydrous okara in a relatively short time in order to improve production efficiency and the like, as described in Patent Document 3, a heating drum or the like is used. It has been practiced to leave okara at a relatively high temperature.

  However, in such a method, energy for heating is consumed, and when oil, natural gas, or the like is used as an energy source for heating, the energy source is used for the combustion, or electricity / gas. In this case, when producing the energy source, harmful substances are released into the atmosphere, so that the load on the environment is relatively large.

  Therefore, it is desirable to find a method with as little environmental impact as possible in a relatively short time even when obtaining dried okara from hydrous okara.

  The present invention has been made in view of the above-described circumstances, and while being easy to manufacture and low in cost, is excellent in plant growth, has a low environmental load, has a high degree of design freedom, and is easy to handle. It aims at providing the plant cultivation material which can be utilized for the objective. It is another object of the present invention to provide a production method that can obtain dried okara suitable for use in the plant cultivation material with a low environmental load and in a relatively short time.

For this reason, the plant cultivation material according to the present invention is:

  ADVANTAGE OF THE INVENTION According to this invention, while being easy to manufacture and low-cost, it is excellent in plant growth, has a low environmental load, has a high degree of design freedom and is easy to handle, and can be used for various purposes. Plant cultivation materials can be provided. In addition, it is possible to provide a method for producing dried okara that can be obtained in a relatively short period of time with a small burden on the environment, which is suitable for use in the plant cultivation material.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Note that the present invention is not construed as being limited to the embodiments described herein.

  The plant cultivation material according to the present embodiment is a plant that can be used as a substitute for cultivated soil or a culture substrate for cultivating plants (for example, small trees, flowers, turf, moss, sedum, fruit). , Plant materials such as vines), plant-derived waste materials such as thinned wood, bark, pruned branches, leaves, grains, grain shells, fruits, fruit peels, seeds, etc. It is of course not necessary to be finely crushed and crushed into small pieces of plant chips, fibers or powders (corresponding to the plant-derived substance according to the present invention; hereinafter also referred to as plant chips etc.) ) As the main component.

Pruned trees produced by pruning or pruning trees such as thinned wood, bark, roadside trees, and parks are mostly incinerated without being effectively used. Since wastes derived from plants can be used, the cost can be reduced, and further, CO ₂ emission accompanying incineration can be suppressed, and the burden on the environment can be reduced.

  In the present embodiment, these plant-derived substances are converted into small plant chips, fibers, or powder using a crusher or the like. The size of the chip, fiber or powder is about 0.5 to 3 mm in length, about 0.5 to 3 mm in width, and about 0.5 to 3 mm in thickness (that is, 0.5 × 0.5 mm to 3 × 3 mm). However, the present invention is not limited to this, and a larger size or a smaller size can also be used.

  Such plant chips, fibers, powders, and the like that are commercially available at garden stores can be used.

  And in the plant cultivation material which concerns on this Embodiment, the dried okara as a fertilizer is mixed with plant origin substances, such as the plant chip | tip adjusted to the predetermined size mentioned above, a fiber, or powder.

  Dried okara is obtained by naturally drying okara (hydrous okara) obtained in the production process of tofu, obtained by applying heat treatment, etc., or by a method found by the inventor described later. It may be obtained.

  In addition, dry okara is less likely to rot than water-containing okara, so the preservability of plant cultivation materials (plant cultivation materials can be distributed for the purpose of sale, etc. It is required to be able to be stored for a relatively long period of time), and is more advantageous than water-containing okara from the viewpoint of plant growth, and is suitable as a fertilizer to be mixed with plant cultivation materials. In addition, since many of the hydrated okara are discarded, it is preferable to use the dried okara obtained by processing this from the standpoint of reducing the cost and reducing the burden on the environment.

  The size of dried okara is 0.5 to 3 mm so that it can be uniformly mixed and dispersed in plant chips, fibers, powders, etc., which are components of the plant cultivation material according to the present embodiment. About a powder or fiber (about 0.5 × 0.5 mm to about 3 × 3 mm sieve) can be used.

  In addition, although what is marketed etc. can be utilized for dried okara, using the dried okara obtained by the method which this inventor discovered by various experimental research as mentioned later uses It is preferable in that it is excellent in growth and can further reduce the load on the environment.

  Here, in the present embodiment, the plant-derived substance and the dried okara are mixed to make a plant cultivation material, but a binder (adhesive) is used to connect the components. .

  As a binder that connects plant chips and dried okara, environmentally friendly water-soluble binders (emulsion adhesives) that have little adverse effects on human bodies and plants can be used. For example, acrylic resin emulsion adhesion An agent can be used. Further, for example, vinyl acetate resin-based, ethylene vinyl acetate resin-based emulsion adhesives, and the like can be used.

Here, the plant cultivation material which concerns on this Embodiment is produced as follows, for example.
(1) First, the above-mentioned plant-derived substance and dried okara are mixed well, for example, by a mixer or the like, so that they are almost uniformly dispersed.

  (2) After that, a water-soluble binder (emulsion adhesive) is added to this mixture by a method such as pouring or spraying, and it is mixed well by, for example, a mixer or manual work to form a paste.

  (3) Next, the paste-like mixture in which the plant-derived substance, dried okara, and the water-soluble binder obtained in (2) above are well mixed is poured into a mold 20 having a predetermined shape (see FIG. 1 (see (A) in FIG. 1), and after pressing and solidifying by a hydraulic press or the like (see (B) in FIG. 1), the plant cultivation material 10 is taken out from the mold 20 (see (C) in FIG. 1).

  (4) After taking out from a type | mold by said (3), the plant cultivation material which concerns on this Embodiment is obtained by making it dry. However, depending on the case, it is possible to solidify into a predetermined shape without pressing.

  In addition, as shown in FIG. 2, in order to protect the plant cultivation material 10 from damage or the like, or when a relatively high strength is required, a mesh (mesh-like) made of metal or other material is formed after molding. The surrounding member 30 having an opening that allows the inside and the outside to communicate with each other in a predetermined manner may be used to surround the plant cultivation material 10 and dry it. At this time, the mesh size can be appropriately selected in consideration of both planting ability and strength. For example, a sieve having a size of about 10 mm × 10 mm to a size of about 50 mm × 50 mm can be used, but it may be less or more. From the standpoint of preventing corrosion, the surrounding member 30 may be made of stainless steel, aluminum, resin, or other plant fiber such as bamboo or wood.

Further, when forming in (3) above, a reinforcing member such as a mesh made of metal or other material (for example, a sieve having a size of about 10 mm × 10 mm to a size of about 50 mm × 50 mm) is added to the mixture. It can also be inserted. From the standpoint of preventing corrosion, the reinforcing member can be made of stainless steel, aluminum, resin, synthetic resin, or other vegetable fiber such as bamboo or wood.
In addition, it is also possible to insert the surrounding member 30 simultaneously with molding instead of or together with the reinforcing member. For example, it can be executed by referring to steps (STEPs) 1 to 8 shown in FIGS.

  By the way, the mesh of the surrounding member and the reinforcing member can be easily engaged with a hook or the like to be attached to the wall surface or the like when used as a unit for greening the wall surface, etc. It is convenient because it is not necessary to provide the plant cultivation material.

  The plant cultivation material according to the present embodiment manufactured in this way is activated by a pyrogenic reaction caused by bacteria such as bacteria contained in the plant chip and the like, for example, for a predetermined period of about 7 days after molding. High temperature. However, the predetermined period varies depending on the environment in which the plant cultivation material is placed, and is therefore mixed.

  For this reason, even if it does not actively dry using electricity, fuel, etc., the material for plant cultivation will naturally be well dried from the inside, and from a relatively long period of time, etc. Can be protected.

  Furthermore, since it is placed in a relatively high temperature state for a predetermined period in this way, the plant cultivation material according to the present embodiment is, for example, when a pest is mixed or when an egg is laid, Since these are killed or the like, it is possible to maintain a hygienic state for a long period of time and meet demands such as long-term storage.

  In addition, after leaving the plant cultivation material to stand for the predetermined period, the plant can be planted on the plant cultivation material.

Here, regarding the mixing of each component in the above (1) and (2), about 70 to 90 weight percent (wt%) of plant chips and the like, about 5 to 25 weight percent (wt%) of dried okara, binder Can be mixed at a ratio of about 5 to 25 percent (% by weight), and the ratio can be appropriately selected according to requirements (use mode of plant cultivation materials, growth state of planted plant, etc.) It is. For example, a large amount of dried okara can be included, or when a strong characteristic is required, a large amount of binder can be included.
In addition, the binder can be used by diluting with water appropriately about 2 to 5 times.

  Further, components other than plant chips and dried okara, for example, wetting agents, inorganic fertilizers, organic fertilizers, fertilizers such as chemical composts, and the like can be mixed as required. In addition, since a moisturizing property can be appropriately adjusted by blending a wetting agent, it can be advantageous for the growth of plants cultivated with the plant cultivation material according to the present embodiment depending on the place of use. Further, depending on the situation, it is allowed to mix sand, soil, and the like.

  The plant cultivation material produced in this way can be made into various shapes as required, for example, a polyhedron such as a cubic shape, a disk shape, a polygonal pyramid shape such as a triangular pyramid, a quadrangular pyramid, a conical shape, etc. It is possible to mold it. Further, for example, after forming into a predetermined shape, it can be cut using a cutter, a saw, or the like, and formed into an appropriate shape, and the degree of freedom in design is high.

  In addition, the plant cultivation material can be placed vertically, placed horizontally, and the like, and also has a high degree of freedom in design from this viewpoint.

  For this reason, according to the demands of diversifying users, various purposes such as home gardens, building verandas, rooftops, wall surfaces, walls, etc. (aesthetics, decorations, blindfolds, sunshades or flower beds, home gardens, etc.) Or, when used as a substitute for a hedge or the like, the plant cultivation material according to the present embodiment is suitable. It can also be used in such a way as to cultivate plants on the rooftop, veranda or garden.

  In addition, the plant cultivation material according to the present embodiment is mainly composed of plant chips and the like, and is obtained by binding dried okara to this with a harmless binder, for example, giving water, Even if it is exposed to rain, placed in water, or attached to a float or the like and floated on the water, for example, muddy water and harmful substances do not flow out. The potential for adverse effects can be minimized.

  Therefore, even when it is used for greening as a countermeasure for heat island in urban areas or when it is placed in an exhibition hall, it does not stain the wall, floor, or rooftop of the building, or deface the exhibition hall. In addition, since there is no fear of exposing residents and users of buildings to harmful substances, the plant cultivation material according to the present embodiment is suitable for use as a greening unit.

  Moreover, since the plant chip etc. of comparatively small specific gravity are used as a main component, weight reduction can be achieved compared with the thing which has soil etc. as the main component.

  Furthermore, the plant cultivation material according to the present embodiment can be handled as one block (block) that can be carried by one or two or three people by forming or cutting to an appropriate size. In this case, there is an advantage that handling is easy and operations for storing, carrying in, and carrying out a plurality of plant cultivation materials can be performed efficiently and quickly.

  Therefore, it is easy to carry in and out of the building and the like, and it is possible to shorten the construction time when greening, and it is easy to change every season. Furthermore, it is advantageous when used as an object in an exhibition or the like that is carried in / out at a relatively short interval or as an advertising medium.

  By the way, the planting of the plant cultivation material according to the present embodiment can be performed on any surface of the plant cultivation material.

When a plant is planted on the plant cultivation material according to the present embodiment, for example, in a flower or the like, a plurality of holes can be opened on the surface by a drill or the like, and roots and seeds can be planted in the opened holes.
Therefore, by considering the planting location and the color of the flower, it is possible to deal with various designs such as flower letters.

  Furthermore, by changing the color of plants and flowers to be planted for each plant cultivation material, when arranging a plurality of plant cultivation materials side by side and viewing them as a whole, a predetermined design (including flower letters etc.) It is also possible to arrange the plant cultivation materials appropriately as configured.

  In the case of a plant that grows densely, such as turf or moss, a plant that has grown to some extent is taken out to a predetermined size, and this is transplanted to the surface of the plant cultivation material according to the present embodiment. By doing so, planting can be performed.

Here, the utilization example of what planted the plant to the material for plant cultivation which concerns on this Embodiment to FIGS. 7-10 is shown.
FIG. 7 shows an example in which a plurality of plants planted on the plant cultivation material according to the present embodiment are arranged in the vertical and horizontal directions and used for hedges and the like.
FIG. 8 shows an example in which the plant cultivation material according to the present embodiment is molded or cut into a shape having a triangular surface facing the plant, and a plant is planted on the material to be compatible with various designs.
FIG. 9 shows the plant cultivation material according to the present embodiment in which a plurality of plants planted in the vertical direction are arranged in a plurality of rows and viewed from the front direction.
FIG. 10 is a view of FIG. 9 seen from the lateral direction and shows a state in which plants are planted on both sides of the front surface and the back surface.

  As described above, according to the plant cultivation material according to the present embodiment, while being easy to manufacture and low in cost, it is excellent in plant growth, has a low environmental load, and has a high degree of design freedom. It is possible to provide a plant cultivation material that is large and easy to handle and can be used for various purposes.

  Moreover, the processing method (production from dried okara) can obtain dried okara suitable for use as a component of the plant cultivation material according to the present embodiment in a relatively short time with a low environmental load. The present inventor found the method by repeating various research experiments.

Here, the processing method found by the present inventor will be described in detail below.
First, in step 1 of FIG. 11 (denoted as S. The same applies hereinafter) 1, for example, in a room having a roof that is not exposed to rain and well-ventilated, or in a room where humidity temperature can be appropriately managed. Carrying out okara (hydrous okara obtained in the process of producing tofu; a concept that includes some naturally dried). Depending on the situation, it is possible to proceed to S2 immediately after the delivery from the person (that is, S1 can be omitted), or for a predetermined period (for example, several hours, several days, or a period in which no corruption occurs). After stopping and letting it dry naturally, it can progress to S2.

  In S2, hydrated okara is put into a rotating drum mixer or the like, and the hydrated okara is agitated and stirred (stirred). Or when carrying out by hand, it spreads on a floor surface, stirring a water-containing okara from predetermined.

  In S3, the yeast extract containing yeast is added to the hydrous okara in the rotary drum mixer, and the hydrous okara and the yeast extract are agitated and mixed in a predetermined manner. Or when performing by hand, the said yeast extract is added by spraying etc. using the spray etc. with respect to the water-containing okara spread on the floor surface in S1, and the water-containing okara and the yeast extract are stirred and predetermined. Mix.

  In addition, the said yeast extract can be suitably diluted with water (for example, diluted about 10 to 20 times with water) and used in order to improve mixing with hydrous okara. In addition, the type, amount, dilution rate, and the like of the yeast extract are appropriately selected and adjusted by observing the growth condition of the plant planted on the plant cultivation material using the dried okara obtained by the treatment method of the present invention. Is something that can be done.

  Here, the yeast extract is not particularly limited, and it is also possible to use a tablet, a granular product dissolved in water, a commercially available microbial culture yeast extract, a yeast extract for food addition, etc. Can be used.

  The yeast extract is supplemented with electrolyzed water containing active oxygen species that is environmentally friendly, low-cost and safe in order to enhance the plant's inherent resistance to pests by promoting the production of ethylene, a plant hormone. Can be done. In addition, a photocatalyst (for example, titanium oxide) for promoting photosynthesis, a rooting promoter (for example, methionine), a moisturizer, or a growth promoting agent for tree maintenance / effective bacteria (for example, trehalo) can be added.

  That is, the growth condition of a plant in which a commercially available yeast extract containing a substance having such various properties other than this is planted on a plant cultivation material using dried okara obtained by the treatment method of the present invention is observed. Thus, various selections can be made.

  In S4, the okara appropriately mixed with yeast extract in S3 is taken out from a rotary drum mixer or the like, or taken out from the floor when mixed on the floor surface, and then taken to a predetermined size (for example, 0.5 m to 1 m square) ) Made of metal (for example, aluminum or stainless steel), wooden, resin, synthetic resin, etc. (mesh size is, for example, about 10 mm × 10 mm) and leveled to a height of about 50 mm. The

  In S5, as shown in FIG. 12, a mixture obtained by mixing okara and yeast extract spread on the mesh obtained in S4 at a height of about 50 mm has a plurality of stages with a predetermined gap (for example, height In a direction, the upper surface of the mixture and the lower surface of the mesh on which the lower mixture is placed are stacked (with a space of about 50 mm) and fermented as desired. This fermentation generates heat from the hydrous okara, and drying is promoted throughout the okara including the inside.

  In addition, as a fermentation place, in order to promote drying, for example, a place that has a roof that is not exposed to rain and is well ventilated, or a room in which humidity temperature can be managed and air can be appropriately sent. However, it is possible to process a relatively large amount of mixture at a time even in a narrow space by placing it on a mesh as described above and stacking it in multiple stages. Efficiency can be increased.

  When left in such a state for several days (for example, about 7 days), the hydrous okara is fermented to a predetermined temperature, the temperature rises, drying is promoted, and components suitable for plant growth (N: nitrogen, P: phosphorus, K: potash, etc.).

In S6, the dried okara obtained in S1 to S5 is taken out from the mesh.
The dried okara thus obtained is suitable as a dried okara used for the plant cultivation material according to the present invention, and can be obtained from the hydrous okara in a relatively short time with a low environmental load. It can be done.

A more preferable processing method will be described below.
In S7, the dried okara taken out in S6 and the hydrous okara of S1 (hydrous okara that has not been subjected to fermentation treatment) are mixed so that the dry okara has a volume of about 50% to 70%. To do.

  In S8, as in S2, the mixture obtained by mixing dried okara and hydrous okara obtained in S7 is put into a rotating drum mixer or the like, and is stirred and unraveled. Or when carrying out by hand, it spreads on a floor surface, stirring the said mixture in a predetermined | prescribed manner.

In S9, as in S3, a yeast extract containing yeast is added to the mixture in the rotary drum mixer, and the mixture and the yeast extract are agitated and mixed in a predetermined manner. Or when carrying out by manual work, the said yeast extract is sprayed using a spray etc. with respect to the said mixture spread on the floor surface, the said mixture and a yeast extract are stirred and mixed predetermined.
In addition, the thing similar to what was already described can be used for the said yeast extract.

  In S10, the mixture obtained by appropriately mixing the yeast extract in S9 is taken out from a rotating drum mixer or the like, or if mixed on the floor surface, taken out from the mixture, and the same size as described in S4 (for example, , 0.5 m to 1 m square) on a metal, wooden, resin, etc. mesh (for example, the size of the sieve mesh is about 10 mm × 10 mm) and leveled to a height of about 50 mm.

  In S11, as described in S5, a mixture of okara and yeast extract spread on a mesh at a height of about 50 mm is mixed into a plurality of stages with a predetermined gap (high height) as shown in FIG. Stack about 50 mm in the vertical direction) and ferment to a predetermined degree.

  If left in such a state for several days (for example, about 7 days), the mixture of dried okara and hydrated okara is fermented to a predetermined temperature and the temperature rises, drying is promoted and the plant grows. (N: nitrogen, P: phosphorus, K: potash, etc.). In addition, in such a case, about 50% to 70% of dried okara that has already been subjected to fermentation treatment is contained, so that the drying is faster and the component composition is more suitable for plant growth.

In S12, the dried okara obtained in S7 to S11 is taken out from the mesh.
The dried okara obtained in S6 and S12 can be uniformly mixed and dispersed in plant chips, fibers or powders when used in the plant cultivation material according to the present invention. The powder can be pulverized, crushed or the like into a powder or fiber of about 0.5 to 3 mm.

  When obtaining dried okara from hydrous okara by the treatment method as described above, drying is promoted by heat generated by fermentation by yeast, so heating using energy based on fossil fuels such as electricity and fuel It is possible to obtain dried okara containing a large amount of nutrients important for plant growth in a relatively short time while minimizing the burden on the environment as compared with the case of using the means.

  Moreover, since the dried okara obtained by the processing method according to the present embodiment has undergone a fermentation process that is maintained at a relatively high temperature, it is actively dried using energy based on fossil fuels such as electricity and fuel. Even without treatment, it will naturally dry well from the inside, and it will be protected from spoilage for a relatively long time.For example, when pests are mixed in hydrous okara or lay eggs Even in such a case, since these are killed or the like, it is possible to maintain a hygienic state for a long period of time and meet demands such as long-term storage.

  The dried okara according to the present embodiment obtained by the above-described processing method is suitable for use as a component of the plant cultivation material according to the present embodiment, but is not limited thereto. It is also useful as a general plant fertilizer.

  In particular, it uses waste organic material, hydrous okara, which is economical and has a very low environmental impact in its treatment process, and is extremely environmentally friendly and safe with no adverse effects on environmental pollution. As fertilizer, its use is expected to expand.
