Description

  The present invention relates to a plant cultivation method, and more specifically, a cellulose fiber state in a natural decomposition process in which natural plants become humus in the natural world, and the cellulose fibers are artificially taken out from the plants, and the cellulose fibers are pulp soil of a plant growth medium. Plant cultivation method.

  Conventionally, as a growth material for plants such as vegetation, it is generally a cultivation method using a humus soil whose pulp has been naturally decomposed by microorganisms, but a plant cultivation method by processing paper pulp is also disclosed (for example, Patent Document 1). In Patent Document 1, a piece of paper that has been decomposed into small pieces by a shreter or the like in a cultivation container made of recycled paper forms a culture layer for plant culture formed so as to absorb the supplied water and contain it. Plant cultivation unit and plant cultivation comprising a rooted plant arranged in a cultivation container so that a root portion is located at least in the upper part and inside of the layer, and the culture layer of paper pieces is used as a plant medium A method is disclosed. This culture layer paper piece is easy to stabilize in quality and performance, can be used for a long period of time, and is taken out as burnable garbage when it is old, so that it can be easily refilled or partially replaced with a new piece of paper in a cultivation container. ing.

JP 2008-301778 A

  However, the culture medium of the plant cultivation unit and the plant cultivation method described in Patent Document 1 described above is still a paper that has been broken down into small pieces, especially in the plant culture layer in which the paper is cut and broken down to about 3 mm by a shredder or the like. As the piece is too large, if the culture layer is rough and the gap is wider than the root thickness of the cultured plant, the root and the paper piece will not be able to adhere to each other and will float, so moisture and nutrients from the paper piece culture layer. Cannot be absorbed sufficiently. In addition, if the paper is left as it is, a plurality of celluloses are hardened and water is not easily absorbed by the piece of paper, and the water retention is poor and the amount of water retained is small. Yes. Furthermore, since it takes time until the paper pieces are naturally decomposed and become a nutrient source, and the cultivated plants cannot absorb the paper pieces pulp as nutrients for the plants, a slow-release fertilizer is also required for the paper piece culture layer. Therefore, the paper piece culture layer decomposed into small pieces serves as a holding material that supports and stabilizes the plant plant, and is not pulp soil as a medium that can supply moisture and nutrients. Therefore, when it becomes old from the appearance, it must be replaced, it must be taken out as trash, and it must be incinerated. Because of these problems, it is suitable for cultivation methods of thick-rooted ornamental plants in small-scale cultivation with artificial objects such as flower pots and planters, but large-scale cultivation such as outdoors and cultivation of plants with thin roots such as turf. There was also a problem that it was not suitable for the method.

On the other hand, the natural pulp growing material is humus as shown in FIG. 19, and the humus is eaten after microorganisms decompose (ferment) plant bodies such as fallen trees 19, and cellulose fibers that are difficult to decompose remain, and are refined by weathering. It becomes cellulose and is further soiled and has high nutrients and water retention. However, humus soil in which cellulose, which is an organic substance, has become soiled, becomes lighter when it dries and scatters in the wind and becomes dusty, and because of its good water retention, it absorbs water and becomes muddy when it becomes finer. Easily spills and becomes dirty. Therefore, although humus soil is suitable for plant cultivation on the earth such as fields and flower beds, there is a problem that it is not suitable for plant cultivation on artificial objects such as structures.

The present invention is intended to solve the problem of the method of cultivating a plant in the state in which such conventional pulp growth material is humus and the problem of the method of cultivating the plant in a piece of paper, and has good water retention. Pulp growing material that has the advantage of humus that is absorbed as plant nutrients (fertilizer) and the good ventilation, and the advantage of paper pieces that do not flow out due to dust scattering and mud. Indoor and outdoor such as vegetable factories An object of the present invention is to provide a plant cultivation method using pulp soil that can be cultivated on all things in greening or the like.

In order to solve the above problems and achieve the purpose, as a result of medium analysis of the process from natural vegetation to humus as shown in FIG. 19, cellulose is the cell wall and fiber of the plant body, Plants grow with the nutrients of cellulose, just like eating meat and bones from animals and growing the body, so the plant growth medium is from cellulose fiber state that can be absorbed by plants to humus. be able to. However, humus has been decomposed and has a problem as indicated above, which is optimal as a plant culture medium due to pluripotent differentiation and fragmentation, but difficult to handle. Cellulose fibers are easy to handle but have a problem of lack of nutrients because they are not sufficiently decomposed. Cellulose fibers that are easy to handle are more suitable as a medium on which everything can be grown easily, especially on man-made objects. Mixing with insufficient fertilizer and water-retaining material as needed. As shown in FIG. 18, the pulp soil P can be an artificially good pulp growth material.

The plant cultivation method according to the first aspect of the present invention is the cell wall constituting the plant body by mechanically or / and chemically treating the plant body of the vegetation (only in the case of pulp products such as waste paper). Cellulose fiber, which is the main component of fiber, is taken out as a single unit, and the cellulose fiber is directly applied to asphalt, concrete, metal, net, stone, gravel, sand, earth, wood board, resin, rubber at a thickness of 50 mm or more A pulp soil P (pulp growing floor material) that can be cultivated as a nutrient source for the new plant body was laid down.

According to a second aspect of the present invention, there is provided a plant cultivation method in which cellulose fibers taken out as a simple substance of claim 1 are packed in a cloth bag or a biodegradable non-woven bag through which a plant can pass roots to form a pulp sandbag, asphalt, concrete The plant is grown on the pulp sandbag by placing, installing and laying directly on the metal, net, stone, gravel, sand, earth, wood board, resin and rubber.

  The plant cultivation method according to the third invention is the pulp soil according to claim 1, wherein the wood fiber, wood chip, water retention material (pumice, shirasu, crushed shell, etc.) and fertilizer are individually or / or mixed with cellulose fiber. Pulp sandbag.

The effect of the first invention is that the pulp soil made of cellulose fibers is taken out in a state where the cellulose fibers are exposed, and absorbs moisture contained in the cellulose fibers by direct contact with the roots of the cultivated plants, and is a carbohydrate. It is a growth medium that can supply moisture and nutrients because a cellulose fiber itself can be decomposed and absorbed as a nutrient source, and it can be easily planted anywhere by simply laying pulp soil. Can be cultivated. Therefore, there is no need for foundation work such as stripping asphalt or concrete or leveling, and plants can be cultivated in a short period of time on everything in an environment where plants can be cultivated. In addition, when plant cultivation is no longer necessary, removal, restoration, and processing are simple, and it is possible to restore the state before construction by simply removing the cultivated plant and pulp soil. The removed plant and pulp soil are composted (degraded by earthworms and microorganisms, etc.) Or incineration.
Furthermore, cellulose is the main component of plant cell walls and fibers, and moisture is stored in the cells through the cell walls and cell membranes, so the water permeability and water retention are very good, and the water retention rate is almost 100%. For example, when cellulose fibers are packed in a container and water is added, the amount of water is almost equal to the volume of the container regardless of the amount of cellulose fibers. Therefore, when the dry cellulose fiber pulp soil is laid with a thickness of 100 mm, water can be retained even if there is a rainfall of 100 mm in the area where the pulp soil is laid, thus serving as a reservoir. The rain that falls more than that is saturated and filtered with cellulose fibers like spring water in the forest, and flows out as clean water. This is the same for humus, and it is proved that flooding is unlikely to occur in forests.
Furthermore, since the pulp soil is a cellulose fiber medium layer, it has good air permeability and is intertwined, so it does not scatter or flow out. Furthermore, since the roots of the plants are entangled with the cellulose fibers, the rooting and retention are good, and the cultivated plants are less likely to come off or peel off.
In addition, when drying, it is very light and easy to carry, can be transported in large quantities, and can be transported by elevator for rooftop greening and the like, so heavy equipment such as cranes need not be used, and transportation costs can be reduced.
Furthermore, as an effect of preserving the global environment, forests can be protected by effectively using thinned wood, which is a wood resource, and pulp such as waste wood and waste paper as plant growth materials. In addition, greening of rooftops, greening of parking lots, greening of schoolyards, greening of industrial complexes, etc. makes it easy to take measures against heat islands and prevent global warming.

The effect of the second invention is that the fiber soil which absorbs water with high water retention and is heavy and stable by packing pulp soil, which is cellulose fiber, into a bag such as a non-woven fabric of biodegradable fiber through which plants can pass roots. It is possible to prevent the soil from flowing out and landslides on slopes (bank slopes, etc.) such as banks and cuts, and at the same time, by planting plants such as turf as a plant growth material, the roots of the plant pass through the sandbag. It becomes a complete ecological greening for disaster prevention by extending into the ground and solidifying the ground, and the pulp soil and biodegradable bags are returned to the soil by natural circulation. In addition, when planting grass in a pulp sandbag beforehand and placing it as a grass sandbag, emergency greening can be handled immediately. Furthermore, by making the bottom of the bag a root-proof or waterproof sheet, it can be planted anywhere in the bag. In addition, the area and layout of greening can be freely changed. The same applies to tray greening.

The effect of the third invention is that wood chips are mixed with cellulose fibers to make pulp soil, so that even if the cultivated plant absorbs all the cellulose fibers as nutrients, the wood chips are naturally broken down into cellulose fibers because they are wood fragments. Takes a long time, cellulose fibers as pulp soil are continuously obtained, and plant cultivation is possible for a long time.
In addition, by making pulp soil mixed with cellulose fibers and water retention materials such as pumice, even if all of the cellulose fibers with water retention capacity are absorbed as nutrients for plants and there is no water retention material such as pumice, it will be used as a growing aggregate Since the remaining cultivated plants can obtain moisture, the cultivation of the plants can be continued by supplying the fertilizer.
Cellulose fibers are cell walls and fibers of plant bodies, and even during plant growth, they become nutrients for cell walls and fibers to become root, stem, and leaf plants, but flowers, fruits, bulbs, etc. Appropriate nutrients are required, and the plant cultivation purpose is achieved by making the pulp soil in which the cultivated plant fertilizer is mixed with cellulose fibers.

An example of defibrating waste paper into cellulose fibers is shown in a partial sectional view of a defibrating machine. It shows that the cellulose fiber becomes pulp soil of the plant medium. The plant cultivation method which laid the cellulose fiber of this invention on the base | substrate as pulp soil is shown with sectional drawing.

Pulp soil made by mixing cellulose fiber with water pumice. Utilization of vegetation resources and environmental conservation through plant regeneration artificial circulation cycle. This shows the natural cycle of plant regeneration.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. The cellulose fiber in the examples is a paper-like pulp obtained by mechanically defibrating old paper such as newspaper, corrugated cardboard, and copy paper with a defibrator and taking out the cellulose fiber, and is also commercially available. . In addition, the pulp soil of this invention is what made the said paper cotton-like cellulose fiber the culture medium in which a plant grows. Pulp sandbags are made of pulp soil packed in bags. The turf sandbag is one in which turf is grown on the upper surface of the pulp sandbag and the lawn and pulp sandbag are integrated.

  FIG. 1 shows a process in which used paper 1 is mechanically defibrated by a defibrator K and cellulose fibers are taken out. When the used paper 1 is put into an input port of the defibrator K, it is sent by a feeder to be coarse. The cellulose fibers 2 are recovered by defibration, middle defibration, and cotton defibration, and packed in a bag or box. The cellulose defibrating 2 of the present invention is not limited to this defibrating method.

FIG. 2 shows that cellulose fiber becomes a plant culture medium. FIG. 2A shows cellulose fiber 2 in which used newspaper 1 has been defibrated by defibrating machine K, and cell walls and fibers of the plant body. Are intertwined into a paper flocs. FIG. 7 (b) shows the water retention of cellulose fibers by a single cellulose fiber 2. When the cell wall 4 is exposed and the cell wall 4 is exposed, the cell wall 4 and the cell membrane (not shown) are shown. ), And the entire cellulose fiber 2 including the cell wall 4 and the cell membrane (not shown) is filled with water 3 to form a water mass with a water retention rate of 100% (the humus soil has almost the same properties). ). The figure (c) absorbs the water 3 contained in the cellulose fiber 2 by the roots 6 of the plant 5, and at the same time forms a carbohydrate plant by carbon dioxide assimilation by carbon dioxide and solar energy in the atmosphere. Since cellulose fiber 2 itself, which is a carbohydrate, is also decomposed and absorbed directly as a nutrient source for producing a plant body, cellulose fiber 2 supplies water and nutrients, so that it is pulp soil P of a plant growth medium. It is shown.

FIG. 3 shows a plant cultivation method using cellulose fiber 2 of claim 1 as pulp soil P. Asphalt with cellulose fiber 2 defibrated from newspaper waste paper 1 by defibrating apparatus K as pulp soil P, Directly spread over 50 mm thick on the base 7 such as concrete, metal, wood board, rubber, synthetic resin, net, stone, gravel, sand, earth, etc., and grow plants 5 such as turfgrass, trees etc. as plant growth medium The growth state of the root 6 etc. which were done is shown with sectional drawing.

FIG. 4 is a photograph of cultivating turf 51 on asphalt 71, concrete 72, and iron plate 73 for one year by a plant cultivation method using cellulose fiber 2 of claim 1 as pulp soil P, and was planted on the general ground. It shows that both roots and leaves grow better than turf.

The turf 61 of 51 is a growth photograph showing a state where the cellulose fibers 2 are deeply stretched and stretched in the pulp soil P and are intertwined. In the same figure (b), when the golf club 11 is rubbed strongly on the upper surface of the turf 51, the turf root 61 will not come off or the turf will not peel off even if the leaves of the turf 51 are broken and dents U are formed. A test photo showing good retention.

FIG. 8 is a photograph of growing a daikon radish 52 in a plastic container 74 as an example of a plant cultivation method on a synthetic resin using the pulp soil P that is the cellulose fiber 2 of claim 1. When the seeds of radish (not shown) are sown by spreading cellulose fiber 2 as pulp soil P in 74 and sowing radish seeds (not shown), the roots 62 of the radish 52 are the pulp soil P as shown in FIG. In the cellulose fiber 2, the elongation is good and long, so the area for absorbing moisture and nutrients is widened and the growth is fast. When the radish radish 52 is eaten, the leaf portion H and the root portion N are separated, the leaf portion H is eaten, and the root portion N is converted into the cellulose fiber 2 as shown in FIG. Since the silkworm root 62 is an organic pulp soil P which is integrated and stretched, it can be put out as burnable garbage or compost and is environmentally friendly.
Thus, the pulp soil P which is the cellulose fiber 2 can be very utilized as a clean medium in an indoor vegetable factory in the future. In particular, root vegetable cultivation is expected.

FIG. 9 shows an example in which the cellulose fiber 2 of claim 2 is packed in a bag as pulp soil P to obtain a pulp sandbag D on which a plant can be cultivated. As shown in FIG. A bag 12 of degradable nonwoven fabric can be packed into a pulp sandbag D for water absorption and landslide prevention as shown in FIG. By planting turf 51 on the top, soil stabilization can be achieved by turf greening as well as sandbag function for water absorption and landslide prevention.

FIG. 10 shows a construction example of a slope disaster prevention greening by a method of cultivating a plant in a pulp sandbag D in which cellulose fibers 2 of claim 2 are packed in a bag. Shows the transport of the pulp sandbag D. The dried pulp sandbag D is light, easy to handle and can be transported in large quantities by the vehicle 13 to the site. FIG. 2B is a cross-sectional view showing a simple laying operation in which the pulp sandbag D is laid side by side on the slope 75 of the embankment at the construction site. FIG. 3C is a cross-sectional view showing a state in which water 3 is sufficiently contained in the laid pulp sandbag D so as to make it heavier and stable and in close contact with the slope 75 of the embankment to protect the embankment. FIG. 4D is a cross-sectional view in which a rooted turf 51 is placed on a pulp sandbag D sufficiently containing water. FIG. 6E is a cross-sectional view showing a state in which the roots (not shown) of the turf 51 are grown by growing cellulose fibers 2 (not shown) in the pulp sandbag D as pulp soil P. . In the figure (f), the biodegradable non-woven bag 12 of the pulp sandbag D and the cellulose fiber 2 which is the pulp soil P in the pulp soil P are decomposed and returned naturally, and assimilated with the embankment of the slope 75, Sectional drawing of the state which became natural weed and became the disaster prevention greening of the ground stability.

FIG. 11 shows a cultivation method in which rooted turf 51 is grown on the upper surface of cellulose sandbag 121 by filling cellulose fiber 2 (not shown) of claim 2 as pulp soil P (not shown) in a bag 121. It is the perspective photograph which showed the turf sandbag S which made the grass 51 root on the pulp sandbag D previously, and was integrated. The bag 121 may be a biodegradable material bag.

FIG. 12 shows a state in which the turf root 61 protrudes and extends from the bottom surface of the turf sandbag S, and FIG. Since it is an eye, it stretches well. The same figure (b) shows how the turf 61 on the bottom of the biodegradable nonwoven bag 122 is stretched. The nonwoven fabric has fine and small eyes, but the turf 61 that has begun to grow is very thin and passes through the nonwoven fabric. Therefore, it extends well in the same manner as the lawn 61 on the bottom of the bag 121. The figure (C) shows how the turf 61 on the bottom surface of the cage 123 extends, and a space of about 10 mm is formed between the bottom surface of the cage 123 and the floor surface to be installed. It does n’t come.
From the above, the bag-type turf sandbag S has the grass roots 61 extending well through the bag to the bottom, so the roots can be fixed on the ground quickly, and the slopes and the foundations of the power transmission tower can be greened. Furthermore, it is suitable as a turf sandbag for immediate use such as disaster prevention greening. In addition, the cage type is suitable for rooftop greening and the like because it does not require root-prevention measures.

FIG. 13 shows a turf mat M in which the bottom surface of the turf sandbag S is made of a root-proof / waterproof sheet, and FIG. 13A shows the pulp soil P in the bag 12 having the bottom surface made of a root-proof / waterproof sheet 14. A lawn mat M stuffed with cellulose fibers 2 and turf 51 grown on its upper surface is shown in a cross-sectional view. (B) is a side view of the lawn mat M. Since 61 (not shown) and water 3 (not shown) do not come out, it can be treated as a greening mat anywhere, and the environment and greening by the grass 51 can be enjoyed.

FIG. 14 shows an example of the use of the turf mat M, and FIG. 14 (a) is a plan for greening the turf mat M on the roof of the heavy equipment for construction 15 as a countermeasure against the heat island of the iron plate in the summer. The construction heavy machine 15 can be easily put on and off without getting dirty or scratched, and the water can be applied to the turf 51 to make the work cooler. Also, heat island countermeasures can be easily taken by the greening method in which turf mats M are laid on steel plates such as gas tanks, oil tanks, ships and industrial complexes. As shown in FIG. 6B, when greening the rooftop O or the like in units of the turf mat M and the turf tray T, a root-proof sheet is not necessary, and the greening area and the greening layout can be freely changed.

FIG. 15 shows that when turf 51 is cultivated for about three years on pulp soil P (not shown) which is cellulose fiber 2 (not shown), cellulose fiber 2 (not shown) is absorbed by turf 51 as a nutrient. Since it becomes a nutrient source for roots, stems and leaves, only the grass root 61 remains between the turf 51 and the base 7 like fiber of the silkworm, and the nutrients and water-retaining substances are lost.

FIG. 16 shows a cultivation method in which wood chips that are naturally decomposed to become cellulose are mixed so that the cultivated plant does not wither due to lack of nutrients even if the cellulose fibers 2 that are the pulp soil P of claim 3 are all absorbed as nutrients. FIG. 2A shows an example of pulp soil P obtained by mixing cellulose chips 2 with fine pieces, small pieces, medium pieces, and large pieces of wood chips 16. The figure (b) is a cultivated turf 51 laid directly on the base 7 with pulp soil P in which cellulose chips 2 are mixed with microchips, small pieces, medium pieces, and large pieces of wood chips 16. Even if all of the cellulose fibers 2 become nutrients and are absorbed by the turf 51, the wood chip 16 is naturally decomposed into cellulose to become pulp soil P so as to replace it, so that the turf 51 can continue to grow. In addition, the wood chip 16 can be mixed to make the pulp soil P that can be cultivated for a long period of time in which the turf 51 does not die for five years or more by giving a width to the period during which it naturally decomposes to become cellulose.

FIG. 17 shows that cellulose fiber 2 is mixed with cellulose fiber 2 so that the cultivated plant does not wither due to water depletion even if cellulose fiber 2 which is pulp soil P of claim 3 is completely absorbed as nutrients. It is an example of a cultivation method that can be retained as a water retaining material even when 2 is lost and water can be secured. FIG. 2 (a) shows the base 7 as pulp soil P by mixing cellulose fibers 2 with water retaining pumice 17 It was laid directly on top and cultivated with rooted grass 51. In the same figure (B), even if the cellulose fiber 2 (not shown) is completely absorbed by the turf 51 as a nutrient, the pumice 17 remains as the growth aggregate Z, and water penetrates into countless holes. In addition, since the water retention is high, the turf 61 can sufficiently absorb moisture. Therefore, the turf 51 can be continuously cultivated on the base 7 by performing the fertilizer 18. In addition, the withering of the turf 51 in winter can be delayed and prevented. Furthermore, since the pumice 17 is tightened and the turf 61 is entangled, the turf 51 can obtain a stable treading pressure.

FIG. 18 shows the plant regeneration artificial circulation cycle and the environmental effect by the pulp soil P composed of the cellulose fiber 2 of the present invention, and restores the leaves, branches, trunks, roots, grasses and pulp products. Cellulose fibers 2 are artificially taken out in the state of 19 plant regeneration natural circulation cycles, and by growing the plant as pulp soil P, regeneration circulation can be accelerated, thinned wood, waste wood, pruning branches, grass, enabled promote the use of vegetation resources, such as waste paper, and Hakare the heat island measures and environmental improvement in the greening of urban areas due to global warming prevention and pulp soil P such as CO ₂ reduction in forest protection of the global environment conservation Become.

FIG. 19 shows a natural cycle of plant regeneration that turns into humus due to fallen trees, decomposition, weathering, and soiling in nature. Fallen tree 19 is decomposed by microorganisms into cellulose fibers, and further, As weathering progresses, the fibers are cut into cellulose, and the finely divided cellulose is turned into soil and becomes humus. The fallen tree 19 becomes a growth medium because the fallen tree 19 is absorbed by the plant as the decomposition progresses to cellulose fibers, and the plant grows as a pulp growth medium up to humus. Cellulose fibers have a problem that decomposition is insufficient and nutrients are insufficient and fibers are difficult to be absorbed. However, cellulose fibers are easy to handle in a fiber state, and are suitable for greening or plant cultivation on artificial objects such as structures. Although the humus state has fine particles and is difficult to handle because it tends to become dust and mud, it is suitable for revegetation and plant cultivation on the land such as fields and flower beds because it has decomposed and is nourished.
