Description

  The present invention relates to a planting sheet for planting plants in soil as a planting place, a method for producing a planting sheet, and a planting method using the planting sheet.

  Conventionally, when plants such as flowers are vegetated on soil, many seeds are sown directly on the soil by hand, and the seeds are germinated by flooding or the like to grow the plants. However, direct seeding of a large number of seeds in a wide range of soil is cumbersome and time-consuming, and it is difficult to sow a large number of seeds almost uniformly.

  As a countermeasure for this, for example, there has been proposed one in which seeds and fertilizers are arranged at approximately equal intervals on one continuous cover sheet and are integrally fixed by a dissolvable resin plate (for example, Patent Document 1). See).

By laying the cover sheet so as to cover the earth floor (soil), it is possible to reduce time and labor for seeding a large number of seeds and to seed a large number of seeds almost uniformly.
Japanese Patent Laid-Open No. 11-123006

  However, the cover sheet described in Patent Document 1 has a long drying period (for example, at least 1 week to 15 days or more) after seeds are sown and there is a small amount of rainfall in the case of seeds that are difficult to germinate. When they occur, the roots that initially rooted often dry and die. This is because when seeds are sown on the earth floor, seeds germinate after several days (for example, 1 week to 15 days) after rooting, so that a drying period occurs between rooting and germination. Therefore, it is considered that the cause is dry dying without germination. For this reason, the germination probability of seeds decreases, and the plant cannot be stably vegetated. Moreover, in the case of public works planted in the center of a road, sidewalks, parks, etc., the problem of dry mortality becomes more prominent because water cannot be flooded at all times.

  Moreover, in order to produce the cover sheet described in Patent Document 1, it is necessary to collect a large number of seeds or purchase a large number of seeds, which is costly.

  This planting sheet 10 includes a cut sheet 14 in which a mesh-like cut 12 is formed by shifting the position in a certain direction (longitudinal direction in FIG. 1). A cut sheet 16 formed by a cut-in shape 12 is disposed, and two cut sheets 14 and 16 are bonded together. In this embodiment, the cut sheets 14 and 16 are made of brown (unbleached) flat paper having relatively high water absorption, have low rigidity, and have cushioning properties. Note that the cut sheets 14 and 16 may be cushioned by embossing.

  The cut sheets 14 and 16 are not limited to paper, and plastic sheets may be used. For example, a sheet made of a biodegradable resin having the property of being decomposed by microorganisms in the soil to become carbon dioxide and water may be used. As the biodegradable resin, for example, a polylactic acid resin is used.

  In addition, the cut 12 is a linear cut arranged in a mesh shape. In this embodiment, the length of the cut is about 12 mm, and the interval between the cuts (vertical direction in FIG. 1) is about 3 mm. An interval between adjacent cuts (lateral direction in FIG. 1) is about 2 mm. In addition, this cut dimension can be set suitably.

  FIG. 1B is a developed view of the bonding surface of the two cut sheets 14 and 16.

  Between the two cut sheets 14, 16, a plurality of pulverized products 18 obtained by pulverizing plant leaves, stems and roots and a plurality of water retention agents 20 are dispersed and arranged, and these are adhesives (not shown). Is adhered to the surfaces of the cut sheets 14 and 16. In the present embodiment, the number of the water retaining agents 20 is smaller than the number of the pulverized products 18, but is not limited to this configuration, and even if the number of the water retaining agents 20 and the pulverized products 18 is the same, the number of the water retaining agents 20 is large. It doesn't matter.

  The water-retaining agent 20 is made of highly water-absorbent resin particles that have the property of absorbing moisture and swelling. As the superabsorbent resin, a polymer resin having a reduced degree of cross-linking so that moisture can be easily taken in is used. For example, starch-acrylonitrile copolymer, polyacrylate, starch-acrylic acid copolymer, vinyl acetate -Acrylic ester copolymer saponified products, polyethylene oxide derivatives and the like are used. In the present embodiment, as the water retention agent 20, terracottem (manufactured by Terracottem, Belgium), which is a soil conditioner obtained by blending a superabsorbent resin with fertilizer, growth promoter, carrier and the like, is used.

  As the pulverized product 18, a pulverized mixture of plant leaves, stems and roots is used. In the present embodiment, as the pulverized product 18, crushed leaves, stems and roots of rocky grass are used. The pulverized product 18 includes all of the leaves, stems, and roots of the rocky grass, but may be one obtained by pulverizing any one or more of the leaves, stems, and roots of the rocky grass.

  In the present embodiment, the plurality of pulverized products 18 and the plurality of water retention agents 20 are randomly arranged, but may be arranged at substantially equal intervals. Moreover, the size of the planting sheet 10 is formed in a rectangle slightly larger than the palm size of the user's palm. In this embodiment, the length in the vertical direction in FIG. The length is about 135 mm. This dimension can be set as appropriate.

  Here, the manufacturing method of the planting sheet 10 is demonstrated.

  FIG. 2 shows an apparatus for manufacturing the planting sheet 10. The cut sheet 14A having a large area is wound around the rotary shaft 52 in a roll shape, and the cut sheet 14A is pulled out and conveyed in the arrow direction by the rotation of the conveyance rolls 54 and 55. In this cut sheet 14A, mesh-like cuts 12 (see FIG. 1) are formed in advance.

  On the downstream side in the conveying direction of the cut sheet 14A, a spraying device 56 that sprays the adhesive B in a spray form, a hopper 58 that disperses and drops the plurality of water retention agents 20, and a pulverization that disperses and drops the pulverized material 18 A device 60 is provided. The crushing device 60 includes a cutter 64 inside a hopper 62 that opens upward, and a plurality of pores 66 at the bottom of the hopper 62. The rocky grass 18A is put into the hopper 62 in a raw state (with stems, roots, and leaves), and the rocky grass 18A is pulverized by the cutter 64, and then the pulverized material 18 is cut from the pores 66. It is made to fall on the surface of the sheet 14A.

  Further, a transport roll 68 is disposed downstream in the transport direction from the crushing device 60, and the transport direction of the cut sheet 14 </ b> A is bent at a substantially right angle along the peripheral surface of the transport roll 68.

  On the other hand, the cut sheet 16A is wound around the rotary shaft 70 in a roll shape on the side opposite to the cut sheet 14A. Then, the cut sheet 16 </ b> A is pulled out and conveyed in the arrow direction by the rotation of the conveyance roll 72, and the conveyance direction of the cut sheet 16 </ b> A is bent along the conveyance roll 72 at a substantially right angle. The transport roll 72 is disposed in close proximity to the transport roll 68, and the cut sheet 14 </ b> A and the cut sheet 16 </ b> A are in contact with and pressed between the transport roll 68 and the transport roll 72.

  In such an apparatus, the cut sheet 14A is conveyed in the direction of the arrow by the conveying rolls 54 and 55, and the adhesive B is sprayed from the spraying apparatus 56 onto the surface of the cut sheet 14A. Thereafter, the plurality of water retention agents 20 are dispersed and dropped from the hopper 58, and the plurality of water retention agents 20 are adhered to the surface of the cut sheet 14 </ b> A with the adhesive B. Further, the pulverized material 18 of the rocky grass 18A pulverized by the pulverizer 60 is dispersed and dropped from the pores 66 onto the surface of the cut sheet 14A, and the pulverized material 18 is adhered to the surface of the cut sheet 14A with the adhesive B. . Thereafter, the cut sheet 14 </ b> A is conveyed to the conveyance roll 68. Further, the cut sheet 16A is conveyed by the rotation of the conveyance roll 72, and the surface of the cut sheet 14A sprayed with the adhesive B and the surface of the cut sheet 16A are pressed between the conveyance roll 68 and the conveyance roll 72. Is done. Thus, the cut sheet 14A is bonded to the cut sheet 16A in a state where the water retention agent 20 and the pulverized material 18 are held. The continuous sheet-like planting sheet 50 is manufactured by bonding the cut sheets 14 </ b> A and 16 </ b> A, and the continuous sheet-like planting sheet 50 is wound around the rotating shaft 74. The continuous sheet-like planting sheet 50 is drawn out at the time of use in a state of being wound around the rotating shaft 74, cut into a desired size, and used as the planting sheet 10 shown in FIG. Thereby, the planting sheet 10 can be manufactured by a simple process.

  Next, it is an effect | action of the planting sheet | seat 10, Comprising: The planting method which is one Embodiment of this invention is demonstrated.

  As shown in FIG. 3, when the user pulls both ends of the planting sheet 10 in a direction perpendicular to the direction of the notch 12 (the arrow direction in FIG. 2), the notch 12 is opened to form an opening 12 </ b> A. 10 extends in the direction of the arrow.

  In this state, as shown in FIG. 4, the planting sheet 10 is placed on the soil 2 that is the planting place by the user's hand, and the planting sheet 10 is pushed into the soil 2 by pushing with the palm of the hand. Enter. Thereby, the planting sheet 10 is embedded in the soil 2 so as to form a bowl shape. At this time, because the planting sheet 10 is curved along the stretching direction by gripping the planting sheet 10 so that the stretching direction of the planting sheet 10 matches the longitudinal direction of the palm, It becomes easy to pour into the soil 2. Further, when the planting sheet 10 is stretched in the direction of the arrow in FIG. 3, the pulverized product 18 and the water retention agent 20 are fixed (adhered) with an adhesive, so It can prevent falling from between. Further, when the planting sheet 10 is stretched, the notch 12 is opened and the opening 12A is formed, so that sunlight and air permeability are good and air and moisture are easily supplied, and photosynthesis of the pulverized product 18 is promoted. There is also an advantage that germination is easy.

  As shown in FIG. 4 (A), a plurality of planting sheets 10 are poured on the soil 2 at regular intervals. Then, as shown to FIG. 4 (B), a small amount of soil 4 is covered so that the whole planting sheet | seat 10 may be covered. Thereby, the some pulverized material 18 can be easily sown on the soil 2. At this time, it is not necessary to irrigate the newly covered soil 4.

  As shown in FIG. 4 (C), after seeding the pulverized product 18 and passing several days, for example, roots 22 emerge from the pulverized product 18. At this time, since the opening 12 </ b> A is formed in the cut sheets 14 and 16, the root 22 extends into the soil 2 without staying between the cut sheets 14 and 16. In addition, the water retention agent 20 absorbs moisture in the soil 2 and rainwater during rainfall and swells.

  As shown in FIG. 4 (D), when several days have passed, buds 24 emerge from the pulverized product 18. At this time, since the opening 12 </ b> A is formed in the cut sheets 14 and 16, the bud 24 extends to the surface side of the soil 2 without staying between the cut sheets 14 and 16.

  In such a planting sheet 10, the planting sheet 10 is stretched and inserted into the soil 2, so that the plant is grown directly from the raw pulverized material 18 and the rocky grass 18 </ b> A grows.

  In addition, even after a small amount of rain, after the pulverized product 18 has been sown, sufficient water is supplied to the roots 22 and the buds 24 of the pulverized product 18 from the water retention agent 20 that has absorbed moisture and rain in the soil. Therefore, the plant is less likely to dry and die. Moreover, even when it is difficult to flood regularly in public works such as roads and parks, the crushed material 18 can be easily vegetated, and management becomes easy. Moreover, by extending the planting sheet 10 and inserting the planted sheet 10 into the soil 2, it is possible to reduce the work load when the pulverized material 18 is sowed in a wide range of soil 2, and the work burden can be reduced. Further, since the ground material 18 uses the roots, stems, and leaves of the cut-out rocky grass 18A, it is not necessary to collect or purchase seeds, and the cost can be reduced.

  In the present embodiment, the pulverized material 18 obtained by pulverizing the rocky grass 18A is used. However, the present invention is not limited to this configuration. The pulverized product may be a plant that is directly vegetated from the raw pulverized product. For example, a pulverized product of plants crawling on the ground such as musk grass or sirimakiya can be used. In addition, daikandora (also called dikondora, a perennial seed of the convolvulaceae) can be used.

  In addition, in the planting sheet 10 of this embodiment, the pulverized material 18 and the water retaining agent 20 are held between the cut sheets 14 and 16, but in addition to these, a fertilizer component, an insecticidal component, and the like may be held. . As a result, it is possible to supply fertilizers necessary for the growth of the plant and to prevent the plant from withering by insects and the like. Moreover, you may add a preservative, a soil improvement agent, etc. suitably as needed.

  In addition, in the planting sheet | seat 10 of this embodiment, although the mesh-shaped cut 12 cut | disconnected by linear form is formed, it is not limited to this structure. The plurality of cuts may be configured so that the planting sheet 10 can be extended in a certain direction.
