Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a seedbed capable of growing plants even on asphalt such as a rooftop or a sidewalk of a sidewalk. [0002] Needless to say, conventional urbanization policies are:
The area where plants grow has been reduced, and as a result, problems such as an increase in carbon dioxide, abnormal weather such as warming, changes in ecosystems, and psychological oppression due to artificial landscapes have become apparent. For this reason, greening of urban areas is an important issue when considering urban environments. [0003] Such a problem is at the same time inherent in the problem of how to increase the number of plants in an urban living space without soil. A technique using a structure capable of growing plants has been proposed (for example, Japanese Patent Application Laid-Open No. 9-2898).
In No. 30, the seeds of plants are buried in the joints of structures so that plants can grow from the buildings.) [0004] However, as a simpler solution,
It is a method of creating an environment where plants can grow on asphalt such as the roof of an existing building or the sidewalk of the sidewalk, for example, such as Tokyo, recently instructing it as `` heat island measures '', It is also one of the methods that the administrative agency is working hard to spread. And
Various forms have been proposed for such a technique. [0005] For example, Japanese Patent Application Laid-Open No. H11-89428 discloses that a waterproof sheet is placed on a rooftop asphalt, a water retention sheet and porous concrete having voids are sequentially placed thereon, Technology to form a planting base by arranging planting soil in
No. 4246 discloses a technique in which a synthetic resin mat having a large number of water retention grooves is placed on asphalt, and clay is spread over the mat. In Japanese Utility Model Application Laid-open No. 63-89714, a seeding sheet body is proposed in which a large number of seeds are adhered on a water-soluble paper sheet in which chemical fibers are used as a frame, and a net sheet made of natural fibers is adhered thereon. Kaiping
In Japanese Patent Application Publication No. 11-318204, a plant growing mat in which a plant fiber is crosslinked with a rubber-like substance to form a space suitable for elongation of a plant rhizome is proposed. A substrate for growing plants, which is covered with a covering sheet, has been proposed.On asphalt, such as a rooftop or a shoulder of a sidewalk, or using the technology as it is, or laying a sheet body or the like, However, greening can be achieved on asphalt. [0006] However, in the above-mentioned techniques, the construction process is complicated, the construction scale is inevitably increased, and the cost cannot be reduced. It was not something I could do. In addition, once a plant is planted in the construction site, when changing to another plant, there is also a trouble that all the planted plants must be dug up and pulled out. On the other hand, in the above-mentioned techniques, it is only necessary to lay a relatively small piece of sheet or the like on the asphalt. Therefore, it is sufficient to install and remove the sheet and the like in units of the sheet or the like. No problem,
However, the small-sized sheet body is made of many kinds of materials, and a plurality of manufacturing steps are required, so that a complete reduction in cost cannot be achieved. In addition, in the case of the seeding sheet body, in the plant growing mat of the chemical fiber and the adhesive, rubber or the like as a cross-linking material is required, and it is necessary to use a material other than a natural material. It was completely incompatible with the recent climate of environmental priority that should be used. [0008] In this regard, the plant substrate of the present invention did not have the above-mentioned problems, but since the substrate itself was wrapped with a latex or coconut fiber covering sheet and solidified, a hole was formed in the upper surface, and There was a problem that seeds and seedlings had to be put, and sowing work was troublesome. In addition, there is a problem that weeds cannot be prevented by any of the above techniques, and that other birds can eat seeds by flying birds. in addition,
The mat and the base material cannot effectively prevent the evaporation of water, and have a problem in moisturizing. The present invention has been made in view of the above problems of the prior art, and is easy to install and replace.
In addition, the production cost is low because only natural and natural materials are used.Prevention of weed propagation, prevention of deprivation of seeds and seedlings by bird damage, effective prevention of water evaporation, and various effects are also recognized. It is an object of the present invention to provide a method for producing a seedbed that contributes to the above. [0011] In particular, as a breeding technique for promoting greening in an urban area, a structure that is as simple as possible and that is easy to install and dispose is more likely to promote the spread. Needless to say, it can be achieved. For this reason, the present inventor focused on the above-mentioned plant growing base material that meets such a request among the conventional techniques presented above, and proceeded with the study. By the way, in this embodiment, as described above,
There are difficulties in placing seeds and seedlings to harden the small pieces, and because they are exposed to direct sunlight, they tend to be hot and unavoidable to dry, and have problems with moisture retention (especially on the rooftop etc. In addition, weeds cannot be effectively prevented from breeding, and birds endanger seeds and seedlings. In other words, in other words, if an improvement measure that can solve these problems in the above-mentioned plant growing substrate (Japanese Patent Application Laid-Open No. H11-299345) can be found, all the problems of the prior art can be solved. Technology can be extremely useful in promoting urban greening. Therefore, the inventor of the present invention referred to the above-described plant growing substrate, repeated improvement and testing on the degree and structure of the compression, and as a result, laminated the ones formed by compressing and forming the plant fibers into small pieces. Even if the upper sheet is dried, the lower sheet is appropriately moist, so it is extremely effective in maintaining moisture retention and preventing the propagation of weeds. Is placed on the lower sheet without the risk of birds being tampered with and a good breeding environment with moisturizing conditions. Despite the simple steps, it was found that the seeds and seedlings were firmly fixed by the upper sheet. And, as for the structure of the sheet itself, if the fibers on the contact surface when laminated are compressed to the extent that they can be entangled, simply stacking the sheets will integrate the upper and lower sheets firmly. Also, it has been found that the structure becomes extremely simple because no adhesive or fixing member is required. [0014] Seed bed preparation method according to the present invention, which has been made based on the knowledge obtained by the circumstances described above the present inventors made from plant fibers, the fibers of the surface

It is characterized by being integrated . Here, the entanglement means that when the sheets are laminated, the weight of the upper sheet is the weight of the upper sheet, and the fibers of the contact surface are inserted into the fibers of the contact surface of the lower sheet, while the two fibers are interposed. It refers to a state in which they are intertwined and integrated. Although it differs depending on the plant fiber used, for example, in the case of using coconut fiber, particularly coconut pericarp fiber, there is a type in which the fiber on the surface becomes entangled by itself by compacting and press-forming (see below). Form). Most generally, while a pressing force is required to such an extent that the small pieces do not lose their shape, a pressing force enough to form the fibers firmly is not necessary because no entanglement action is obtained. Since the entanglement action of the fiber surface is used, a step of covering the surface with a cover sheet, as in the case of the above-mentioned plant growing substrate (Japanese Patent Application Laid-Open No. 11-299345), is of course unnecessary. [0017] The seedbed forming sheet is obtained by forming small pieces by compressing them so that the fibers on the surfaces in contact with each other can be entangled with each other when the sheets having the structure are vertically stacked. However, since only vegetable fiber is sufficient, the manufacturing process is extremely simple and the cost is low. The present invention using such a sheet
In this method, the fibers on the mutual surface of the upper and lower sheets are entangled and formed integrally by simply laminating the sheets, so that adhesives and fixing members are not required, making the production extremely simple and cost effective. Is very cheap. In the above manufacturing method, the seeds and the seedlings are firmly fixed only by being placed on the lower sheet surface, so that the seeding operation can be performed very easily. According to this manufacturing method
The seedbed obtained as described above need only be appropriately placed in a place where greening is desired. Since it is in the form of small pieces, it can be placed anywhere, and can be installed on asphalt, such as on the roof or on the sidewalk of the sidewalk. Of course, it may be placed on the soil. In this case, depending on the plant, the root may descend from the lower sheet to the soil, and even if the sheet rots, it becomes a fertilizer for the soil because it is a plant fiber itself. Also, by spraying water on the seedbed obtained according to the present invention, the seeds and the seedlings are moistened through the fibers of the upper and lower sheets. Thereafter, the upper sheet is appropriately dried by solar heat or the like, while the lower sheet is appropriately moist due to the water retention of the plant fibers. This allows
The seeds or seedlings on the lower sheet are blocked from direct sunlight by the upper sheet, while the lower sheet with seeds or seedlings is kept moist by blocking the moisture evaporation by the shielding action of the upper sheet. Also, hydration is performed without any problem. Even if the seeds of the weeds come in, the possibility of germination is extremely low because the upper sheet is dry. Also, for birds that feed on seeds, seeds or seedlings are covered with the upper sheet, so that they can be prevented from being tampered with. An extremely favorable growth environment for the seed or seedling is obtained, and under such an environment, the rhizome freely extends in the fibers in the sheet. As time goes on, the plant fibers, especially in the lower sheet, decay, but, as noted above, because they become fertilizers, the seeds and seedlings will also grow more. [0021] In the case, such as replacing the other types of plants, this
By the method of the invention, by placing the seeds or seedlings of the plant
What is necessary is just to replace the obtained seedbed. Since the seedbed is also in the form of small pieces, the amount to be replaced can be appropriately selected according to the situation. Since the seed beds replaced and replaced are all made of plant materials, they can be used as fertilizers if they are in good condition, and even if they are disposed of, they are all perishable natural products, so that environmental pollution can be minimized. . DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described. It is needless to say that the invention according to the present application is not limited to the following examples. An example in which coconut peel fiber is used as a plant fiber will be described. After loosening the coconut pericarp fiber, push the fiber into a roll press that can be pressed from above and below,
Compression molding. At this time, a natural latex rubber may be appropriately contained and molded in order to prevent the mold from breaking. A strip-like sheet having a thickness of about 10 mm between the fibers is formed, and the sheet is cut at appropriate intervals. The coconut fibers are appropriately air-dried in this step. The small piece assumed in the present embodiment is a rectangular parallelepiped having a side of about 600 mm square in a plan view (about 600 × about 600 × about 10), but its size may be appropriately selected according to the mode of use. As a result, by pressing the amorphous coconut peel fiber,
As a result, a small piece sheet whose surface is appropriately fine and which is appropriately uneven, and whose fibers intersect in a complicated manner, was obtained. When the two small piece sheets are stacked, the fibers on the surfaces in contact with each other are entangled due to the weight of the upper layer side sheet, so that the fibers are not easily displaced even if they are shifted laterally. The more you make the sound, the more you will be integrated. That is, the upper and lower sheets can be easily integrated simply by lamination. A laminate of such sheets is used as a seedbed.
Specifically , seeds and seedlings are placed on the surface of the lower sheet, and then the upper sheet is laminated. Seed bed obtained in this way, as it is placed on a floor, if you give water, will grow seeds or seedlings. In addition, since the seedbed is formed by stacking small pieces of sheets, if seedbeds of seeds of different plants and seedlings are sprinkled and arranged in a tile shape, various flowers can grow side by side, and flowers and grass withered. In such cases, the seedbed itself can be replaced, so management can be performed very easily. Plants can be grown on asphalt as well as on soil, making them ideal as a technology to promote greening especially in urban areas. Although only the coconut pericarp fiber has been described in the above embodiment, it is possible to use any type of plant fiber as long as it can be compression-molded to the extent that other fibers and surface fibers can be entangled with each other. But it doesn't matter. However, it is palms that the fibers are irregular and easy to unite,
Other than coco palm, oil palm, sago palm, date palm and the like are preferable. Although not particularly described in the above embodiment, seeds or seedlings are placed immediately after the sheet is compression-molded with a roll, and further cut into small pieces in a state where another sheet that has already been formed is laminated. If this is done, a small seedbed with seeds or seedlings arranged inside in a series of steps can be produced at once, which is extremely useful. Of course, the production process of the seedbed is not limited thereto. [0027] For EXAMPLES above embodiment will now be described an example of using as a lawn nurseries. First, lawn seeds were scattered at appropriate intervals on the surface of the lower sheet, and the upper sheets were laminated to form a seedbed.
A large number of the seedbeds were spread on asphalt on the roof of the building. Water was sprinkled over the seedbed. As a result, the lawn grew through the fibers of the upper sheet, and its rhizomes became firmly rooted in the lower sheet. The upper sheet was dry, while the lower sheet was moderately wet. The weeds did not grow at all, probably because the upper sheet was dry. Sparrows and pigeons are flying on the rooftop, but the lawn seeds and seedlings are protected in the upper sheet, so they were never attacked. Further, as a result of an experiment conducted throughout the year, the temperature on the roof was lowered by about 5 ° C. in the summer sunshine and by about 5 ° C. in winter in the place where the roof was installed. An effect was observed. Water was not sprayed every day, but at appropriate intervals.However, even in the summer sunshine, the lawn grew lush, and the lower sheet was found to have a significant moisturizing effect. Was. As described above, the seedbed according to the present application is as described above.
According to the manufacturing method , the seedbed-forming sheet is in the form of small pieces, and the seedbed obtained by laminating the sheets is also in the form of small pieces, so that installation, removal and replacement can be performed very easily. . In addition, since it can be placed according to the shape of the placement place, it can be placed at any place. Since the material is basically made of only a natural material called plant fiber, the unit cost is low and there is little problem of disposal. The seedbed manufacturing process is also a very easy task, requiring only the lamination of such sheets.
No. It is also possible to effectively prevent complication of sowing work, breeding of weeds, deprivation of seeds and seedlings by bird damage, evaporation of water, and the like, which could not be solved by the plant growing substrate of JP-A-11-299345. Regarding the seedbed obtained, direct sunlight is blocked by the upper sheet, while the lower sheet is kept moist, so that a good growth environment can be obtained for seeds and seedlings located therebetween. Regarding the seedbed obtained, if a seedbed in which different plants are planted is splintered and arranged in a tile form, a wide variety of gardening places can be created, such as various kinds of flowers can be grown. Furthermore, the grass and flowers of the seedbed obtained wither.
Even if it does, the seedbed can be used as fertilizer. Since the above effects are recognized, the promotion of diffusion is improved, and therefore, it is most suitable especially for the improvement of greening in an urban area. Of course, the seedbed obtained can also be used by placing it on the soil, in which case the roots can be extended into the soil, and the rotten sheet becomes the fertilizer for the soil. It can be used for landscaping and agriculture.
