Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a plant sheet using a succulent plant or other vegetatively vegetative plant, a method for producing the same, and a greening method using the plant sheet.
[0002]
[Prior art]
The temperature rise in urban areas is increasing year by year due to the exhaust heat of air conditioners and the reflection of solar heat by asphalt and concrete. As a measure to alleviate the heat island phenomenon, which has become a problem in urban areas, greening by planting plants such as turfgrass on the roof or roof has become widespread. In actual construction, there are issues such as the load on the building and the material used for the foundation soil.One of the solutions to this problem is a method of planting succulent plants such as sedum and vegetatively vegetative plants. There is.
[0003]
Succulent plants, such as sedum, are extremely resistant to drought and can be grown with a small amount of water. Therefore, they do not require watering means and are suitable for greening places such as rooftops and walls where water retention is difficult. Further, since soil as a planting base is not so required, it is possible to grow even with a thin planting base, and the growing base can be made thin. For this reason, it is possible to reduce the load on the building, and it is an effective greening means in greening a building with a limited load.
[0004]
However, when a succulent plant is transplanted to the soil surface, the foliage of the succulent plant sometimes moves or turns over due to the wind, and may not be properly fixed to the transplanted soil. In addition, since the foliage of the succulent plant immediately after transplantation is in a state of low stress tolerance, the growth of the foliage was hindered when subjected to strong environmental stress such as direct sunlight or wind.
[0005]
On the other hand, there is a construction method in which foliage and seeds are placed on a planting base, covered with a sheet from above, and integrated with the foliage or seeds and the planting base on the soil surface.
[0006]
For example, as shown in FIG. 11, stems and leaves 106 of turf 104 are disassembled and stretched on a net 102 as a planting base, and a water retention agent 108 is sandwiched between sheets 110 and 112 as a watering means thereon. In some cases, both ends and the central portion are sewn together with a sewing machine 114 to integrate the net 102, the turf foliage 106 and the sheets 110 and 112, and fix them to the soil surface of the transplantation destination ( Patent Document 1).
[0007]
However, if this method is used as a fixing means for arranging relatively bulky block-shaped plants, such as succulent plants, on a sheet, the plants will be damaged when they are stitched and integrated. In addition, since the net and the sheet are sewn by the sewing machine, a sewing machine is required, which causes an increase in the cost of the apparatus for manufacturing the sheet.
[0008]
On the other hand, there is one in which a turf seed sheet in which seeds are sandwiched between a sheet and a water-soluble film is fixed to soil (Patent Document 2).
[0009]
However, the seed is sandwiched between the sheet and the water-soluble film and integrated by pressing or adhesive, and is relatively small like a seed or like a turf foliage stretched in a line shape. This method is not suitable unless the thickness is made sufficiently small.

[0011]
[Problems to be solved by the invention]
In view of the above facts, the present invention provides a plant sheet that can be produced at low cost without damaging the plant when a bulky plant such as a succulent plant is sandwiched between the sheets.
[0012]
[Means for Solving the Problems]
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
The plant sheet of the present invention according to claim 1, wherein a mesh-like base sheet, a vegetative propagation plant placed on the base sheet, and a water-soluble coating that covers the plant and is fixed to the base sheet. , Consisting of
[0014]
According to the first aspect of the present invention, the vegetative propagation plant is placed on the mesh-like base sheet, covered with the water-soluble coating from above, and fixed to the base sheet.
[0015]
In this way, by covering the vegetative propagation plant with the water-soluble coating, a bulky plant, such as a succulent plant foliage or a lawn runner, is tightly fixed to the base sheet without being damaged. Further, since the water-soluble coating covers the plant, the environmental stress applied to the plant is reduced, and the plant is fixed on the base sheet, which has a favorable effect on the subsequent growth state.
[0016]
Furthermore, since the plant sheet is composed of the base sheet and the water-soluble coating, it does not require soil and is extremely lightweight, leading to a reduction in transportation and unloading costs.
[0017]
The plant sheet of the present invention according to claim 2, wherein the base sheet is a biodegradable sheet, and the water-soluble coating is a paper-like sheet formed of a water-soluble resin material and a fibrous material. The sheet is fixed to the biodegradable sheet.
[0018]
According to the second aspect of the present invention, a biodegradable sheet is used as a base sheet, and a paper-like sheet formed of a water-soluble resin material and a fibrous material is fixed to the base sheet.
[0019]
By using the biodegradable sheet as a base sheet, the base sheet is decomposed into soil, thereby preventing soil contamination. Further, the paper-like sheet dissolves in water, and the fibrous material of the paper-like sheet becomes entangled with the plant, causing the plant to adhere to the ground sheet or the soil surface (including the wall surface of the structure). Further, the paper-like sheet also has an effect as a mulching material, and can prevent invasion of weeds, drying of soil, and erosion by rainwater.
[0020]
The plant sheet according to the third aspect of the present invention is characterized in that a net is provided between the plant and the paper-like sheet.
[0021]
According to the third aspect of the invention, by providing a net between the plant and the paper-like sheet, long-term stability of the surface of the plant sheet can be obtained. These are suitable for plant sheets used for slopes and the like that require stability.
[0022]
The method for producing a plant sheet of the present invention according to claim 4 is a first step of placing a vegetative propagation plant on a mesh-like base sheet, and covering a water-soluble paper sheet on the plant. A second step, a third step of spraying water on the paper-like sheet, and a fourth step of sucking air between the base sheet and the paper-like sheet. .
[0023]
According to the fourth aspect of the present invention, a vegetative propagation plant is placed on the base sheet, and the plant is covered with a paper sheet. When water at a predetermined temperature is sprayed on the paper-like sheet, the air permeability of the paper-like sheet is lost. Next, when the air between the base sheet and the paper-like sheet is sucked, the suction effect causes the paper-like sheet to adhere closely to the shape of the plant, and in a portion where no plant is placed, the paper-like sheet is placed. Adheres to the base sheet. In this way, the plant is closely fixed to the base sheet. Further, since the plant is covered with the paper-like sheet, the paper-like sheet reflects the direct sunlight and prevents direct sunlight from hitting the plant.
[0024]
In the method for producing a plant sheet according to the fifth aspect of the present invention, in the fourth step, air between the base sheet and the paper-like sheet is brought into close contact with each other by sucking air from a lower surface of the base sheet. It is characterized by promoting drying.
[0025]
According to the invention as set forth in claim 5, when the air between the base sheet and the paper-like sheet is sucked from the lower surface of the base sheet, the base sheet and the paper-like sheet are sufficiently adhered to each other by the suction, and then the fine A hole is opened and the drying process starts. Normally, the drying process is completed only by suction, but if the holes are uneven, the air flow is uneven around the holes, causing unevenness in drying, and time is required for drying the entire paper sheet. It costs. Therefore, if air (for example, natural wind, warm air, or hot air) is blown from above the paper-like sheet, the paper-like sheet can be efficiently and uniformly dried.
[0026]
The method for producing a plant sheet according to the present invention according to claim 6 is characterized in that the paper-like sheet exhibits water solubility at room temperature or higher.
[0027]
According to the invention described in claim 6, a plant sheet is produced using a paper-like sheet that exhibits water solubility at room temperature or higher, for example, at 25 ° C. or higher. If the humidity is very high, the paper-like sheet becomes moist due to the humidity and is dissolved. Therefore, for example, by using a material that exhibits water solubility at 25 ° C. or higher as a paper-like sheet, even when the plant sheets are stored in an overlapping manner, by adjusting the room temperature of the storage place to a predetermined temperature. Further, it is possible to prevent the paper-like sheet covering the plant from adhering to the base material of the plant sheet stacked thereon.
[0028]
In addition, normal temperature is a concept in consideration of the regional temperature difference. For example, when using a plant sheet in Hokkaido, water solubility should be exhibited at 15 ° C or higher, and in Okinawa, water solubility should be exhibited at 30 ° C or higher. It is assumed that.
[0029]
The method for producing a plant sheet according to the present invention described in claim 7 is characterized in that the plant is a foliage of a vegetatively vegetable plant cut from a parent seedling.
[0030]
According to the invention as set forth in claim 7, the plant sheet is manufactured from foliage cut off from a parent seedling of a plant capable of vegetative propagation.
[0031]
The plant used for the plant sheet is obtained by cutting off the foliage when the state of the parent seedling is the best, which leads to favorable growth of the plant thereafter. In addition, if only a certain amount of parent seedlings are possessed, materials necessary for transplanting to a large area can be supplied in a short period of time, so that it is possible to sufficiently respond to sudden large orders and short delivery orders.
[0032]
The method for producing a plant sheet according to the present invention according to claim 8 is characterized in that the distribution density of the foliage with respect to the base sheet is inversely proportional to the growth rate.
[0033]
According to the invention described in claim 8, the plant sheet is distributed on the base sheet at a density inversely proportional to the growth rate of the foliage and is manufactured.
[0034]
Since the growth rate of the plant is high, it is not necessary to place the foliage on the base sheet without gaps, and it is only necessary to provide an appropriate gap in the base sheet in consideration of the growth rate and distribute them. For this reason, a plant sheet can be manufactured with a small amount of foliage, and the cost is low. This gap is necessary for the integration of the base sheet 14 and the paper-like sheet 26 and the close contact between the base sheet 14 and the soil.
[0035]
The method for producing a plant sheet according to the present invention described in claim 9 is characterized in that the paper-like sheet is white.
[0036]
According to the ninth aspect of the present invention, by making the paper-like sheet white, the plants are less affected by temperature rise, ultraviolet light, drying, and the like, and a high survival rate can be secured.
[0037]
The method for producing a plant sheet according to the present invention according to claim 10 is characterized by comprising a step of fixing the plant with a net between the first step and the second step.
[0038]
According to the tenth aspect of the present invention, the plant is placed on the base sheet, the plant is fixed with a net, and the plant is covered with the paper sheet. By fixing the plant with the net, a plant net that is not damaged by wind and rain during the curing period until the plant takes root in the soil is manufactured.
[0039]
The method for producing a plant sheet according to the present invention described in claim 11 is characterized in that seeds are sprayed on the base sheet instead of the plants.
[0040]
According to the eleventh aspect of the invention, the seeds are placed on a mesh-like base sheet, covered with a water-soluble coating from above, and fixed to the base sheet.
[0041]
As described above, by covering the seeds with the water-soluble coating, the water-soluble coating covers the seeds, relieves environmental stress applied to the seeds before germination, and the seeds are fixed on the base sheet, and are good for germination and growth. Have an effect.
[0042]
The plant sheet greening method of the present invention according to claim 12 is characterized in that the plant sheet according to any one of claims 1 to 3 is attached to a soil surface with a fixing pin and watered. .
[0043]
According to the twelfth aspect of the present invention, the plant sheet is attached to the soil surface with the fixing pin, and water is sprinkled over the plant sheet attached to the soil surface to fix the plant sheet to the soil surface.
[0044]
Greening of the soil surface can be achieved simply by attaching the plant sheet with fixing pins and sprinkling water from above. Spraying also makes it easier for the entire sheet to adapt to the soil. Furthermore, the resin content of the paper-like sheet is moored around the foliage of the plant, and the resin component is redissolved by watering and penetrates into the soil, so that the plant sheet is firmly fixed to the soil, The sprinkled water is retained by the resin, and serves as a water supply source to the foliage.
[0045]
The plant sheet greening method of the present invention according to claim 13 is characterized in that the plant sheet is placed on a soil surface and sprinkled with water from above.
[0046]
According to the thirteenth aspect of the present invention, the soil is put on the plant sheet placed on the soil surface, and water is sprinkled. In this case, the soil is fixed to the paper-like sheet by the dissolved paper-like sheet, and the soil is less likely to be scattered or run off due to wind and rain.
[0047]
BEST MODE FOR CARRYING OUT THE INVENTION
A method for producing a plant sheet according to the first embodiment and a greening method using the plant sheet will be described.
[0048]
FIG. 1 shows a manufacturing process of the plant sheet 10.
[0049]
A base sheet 14 serving as a base of the plant sheet 10 is wound around a core 12 installed on the sending side. One end of the base sheet 14 is pulled out horizontally from the winding core 12, sent to a feed roller 16, and wound on a winding core 18 provided on the winding side.
[0050]
The base sheet 14 has a long mesh shape. For example, when a cotton-made cotton is used, the root of a plant (for example, a succulent plant such as sedum) easily penetrates the mesh of the base sheet 14 and penetrates into the soil. Another advantage is that the base sheet 14 is easily adapted to the soil. Furthermore, if the material used for the base sheet 14 is biodegradable, the base sheet 14 is decomposed into soil when attached to the soil surface, thereby preventing soil contamination.
[0051]
A hopper 20 into which foliage 22 such as a succulent plant is put is provided between the core 12 and the core 18. If a parent seedling of a vegetatively breedable plant is held, and only a necessary amount of foliage is cut out from the parent seedling and put into the hopper 20, materials necessary for transplanting to a large area can be supplied in a short period of time. It can respond to large orders.
[0052]
From the hopper 20, the foliage 22 is uniformly arranged on the base sheet 14 (shown in FIG. 2), and the base sheet 14 moves horizontally and proceeds to the next step. The foliage 22 proliferates so as to cover the entire base sheet 14 by making the distribution density with respect to the base sheet 14 inversely proportional to the growth rate and uniformly disposing the gaps. This gap is necessary for the integration of the base sheet 14 and the paper-like sheet 26 and the close contact between the base sheet 14 and the soil.
[0053]
A long paper sheet 26 having substantially the same width as the base sheet 14 is wound around the core 24 provided between the core 12 and the core 18. When the base sheet 14 on which the foliage 22 is disposed is sent below the core 24, one end of the paper-like sheet 26 is pulled out horizontally and covers the base sheet 14 (shown in FIG. 3). As the paper-like sheet 26, a sheet in which a water-soluble resin and fibrous material are entangled is used. As the water-soluble resin, polyvinyl alcohol and starch are suitable. Further, by using the paper-like sheet 26 exhibiting water solubility at a temperature of 25 ° C. or higher, the sheets can be prevented from adhering to each other during storage and transportation after the production of the plant sheet 10. Furthermore, by using a white paper-like sheet 26, the foliage 22 in a state of low stress tolerance after transplantation is prevented from receiving stress such as temperature rise, ultraviolet light, and drying, and the soil of the foliage 22 is prevented. A high survival rate on the surface 36 can be secured. The white sheet may be formed by, for example, spraying a colorant on a non-white paper sheet.
[0054]
A sprayer 28 is provided between the core 24 and the core 18. A predetermined amount of water is sprayed onto the paper-like sheet 26 from the sprayer 28 (shown in FIG. 4). When the paper-like sheet 26 absorbs water, the glue on the sheet becomes rich, the eyes are clogged, and the air permeability is lost. Note that the water-soluble resin is given a predetermined temperature-sensitive property so that the paper-like sheets 14 can be prevented from adhering to each other due to dew condensation or the like during storage and transportation.
[0055]
A suction device 30 is provided between the sprayer 28 and the core 18 in contact with the lower surface of the base sheet 14. The suction device 30 is set to a negative pressure by the connected vacuum pump 32, and sucks the air between the base sheet 14 and the paper-like sheet 26 from the lower surface side of the base sheet 14 through the vent hole 31 (see FIG. 5 or FIG. A)), and the paper sheet 26 is adhered along the foliage 22 (shown in FIG. 6 or FIG. 7B). The paper-like sheet 26 adheres to the portion of the base sheet 14 where the foliage 22 is not placed by suction, and the foliage 22 is firmly fixed to the base sheet 14 without shifting left and right.
[0056]
A hot air heater 34 is provided between the suction device 30 and the core 18. When the paper-like sheet 26 is sufficiently adhered by suction from the lower surface of the base sheet 14, fine holes are opened and the process of drying is started. However, if the distribution of the holes is uneven, the air flow is biased around the holes, so that the drying is performed. And it takes time to dry the entire paper sheet 26. In that case, air is blown from above the paper-like sheet 26 by a warm air blower or a blower 34 to promote drying of the paper-like sheet 26. Note that the hot air blower or the blower 34 is not always necessary.
[0057]
The plant sheet 10 manufactured in this manner is wound around a core 18 and formed into a roll.
[0058]
Next, a greening method for attaching the plant sheet 10 to the soil surface 36 will be described.
[0059]
The plant sheet 10 is cut into an appropriate size and placed at a predetermined position on the soil surface 36 to be transplanted. As shown in FIG. 8, the plant sheet 10 is fixed to the soil surface 36 using the fixing pins 38, and watering is performed from above the plant sheet 10. When watering is performed, the entire plant sheet 10 is easily adapted to the soil surface 36 and is fixed to the soil surface 36. Further, when the resin component of the paper-like sheet 26 accumulated around the foliage 22 is redissolved, the resin is immersed in the ground sheet 14, the bite of the entire ground sheet 14 into the ground soil is improved, and water is sprayed. The water is retained in the resin and becomes a source of water for the foliage.
[0060]
As shown in FIG. 9, the plant sheet 10 fixed to the soil surface 36 takes root on the soil surface 36, roots several times from the foliage 22, and takes root on the soil surface 36 without fail and breeds. Go. FIG. 8 or FIG. 9 is a diagram assuming greening of the slope, but the object of the present greening method is not limited to the slope. Also, instead of watering, a slurry-type vegetation base material for spraying may be used.
[0061]
Next, the method of manufacturing the plant sheet according to the first embodiment and the function of the greening method using the plant sheet will be described.
[0062]
In the method for producing a plant sheet according to the present invention, a special method such as sewing is not required to fix and integrate the base sheet 14 and the paper sheet 26 with the foliage 22 therebetween. That is, in the manufacturing process of the plant sheet 10, the foliage 22 is adhered to the base sheet 14 by moistening the paper sheet 26 and sucking air from the lower surface of the base sheet 14. Therefore, the bulky foliage 22 can be integrated with the base sheet 14 and the paper-like sheet 26 without being damaged.
[0063]
Although the paper-like sheet 26 is used to cover the foliage 22 with the water-soluble coating, a water-soluble solution may be sprayed on the foliage 22 to form the water-soluble coating.
[0064]
Next, a method for manufacturing a plant sheet according to the second embodiment will be described.
[0065]
In the second embodiment, as shown in FIG. 10, a core 40 is provided between the core 12 and the core 24, and the core 42 has a long net 42 having substantially the same width as the base sheet 14. Is wound. The foliage 22 is placed on the base sheet 14 sent from the core 12, and one end of the net 42 is pulled out from the core 40 and placed thereon. Subsequent steps are the same as in the first embodiment, and will not be described.
[0066]
Next, the operation of the method for producing a plant sheet according to the second embodiment will be described.
[0067]
As shown in FIG. 10, by providing the net 42 between the foliage 22 and the paper-like sheet 26, the stability of the surface of the plant sheet 10 can be obtained. Further, if the net 42 is used, a plant sheet 10 suitable for construction on a slope or the like that requires stability of the surface against wind and rain can be manufactured until the plants take root.
[0068]
Next, a greening method using the plant sheet according to the third embodiment will be described.
[0069]
The plant sheet 10 produced in the first embodiment and the second embodiment is cut into an appropriate size and placed at a predetermined position on the soil surface 36 to be transplanted. The soil is put on the plant sheet 10 and water is sprinkled on the top to fix the plant sheet 10 to the soil surface 36. The following is the same as in the first embodiment, and will not be described.
[0070]
Next, a greening method using the plant sheet according to the third embodiment will be described.
[0071]
The soil is put on the plant sheet 10 placed on the soil surface 36 and sprinkled. By providing the soil on the plant sheet 10, the plant sheet 10 is fixed to the soil surface 36, and is easily adapted to the soil surface 36 by watering.
[0072]
In addition, the greening method using the plant sheet 10 of the present invention has less stress, such as damaging the roots of the plant, as compared with the method of sowing the plant directly on the soil surface, so that it can be constructed only until the middle of June in the past. On the other hand, the construction period has become longer, for example, it will be possible until early July.
[0073]
In the embodiment of the present invention, a succulent plant is used as a vegetative propagation plant, but the present invention can be applied to turf and the like.
[0074]
In addition, in applications such as for flat lands and rooftops, it is desirable that the material of the base sheet 14 be decomposed and integrated with the soil in the long term, but for surfaces that require long-term surface stability. Not only that, but it is possible to respond appropriately to the application by properly using the materials of the net.
[0075]
Further, in the step of spraying water for the production of the plant sheet 10, the plant sheet 10 is put on the soil surface 36 by mixing a chemical for controlling pests, a rooting promoter, a fertilizer, a coloring agent, etc. into the water in the sprayer 28. When mounting, complicated and difficult work such as chemical treatment can be performed reliably and efficiently.
[0076]
In the manufacturing process of the plant sheet 10, the manufactured plant sheet 10 is wound around the core 18 and roll-produced, but may be folded.
[0077]
Examples of vegetatively vegetative plants used in the plant sheet of the present invention include succulent plants (eg, sedum, pinewood, cactus, etc.), turf, mint, bamboo, bamboo grass, coral, and the like.
[0078]
【The invention's effect】
Since the present invention is configured as described above, it can be manufactured at low cost without damaging plants when bulky plants such as succulents are sandwiched between sheets.
