Description

  The present invention relates to a planting sheet for planting plant seeds on soil as a planting place, and a planting method using the planting sheet.

  Conventionally, when seeds of plants such as flowers are sown on soil, many seeds are sown directly on the soil by hand. 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 various seeds almost uniformly.

  As a countermeasure for this, for example, there has been proposed one in which seeds and fertilizers are arranged at equal intervals on a single 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, they germinate after several days (for example, 1 week to 15 days) after rooting from the seeds, 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, there is a problem that the germination probability of seeds is lowered and plants cannot be 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.

  The present invention has been made in view of the above problems, and reduces the work burden when sowing a large number of seeds in the soil as a sowing place, and increases the germination probability of seeds even if the drying period continues after sowing. It aims at providing the planting sheet and planting method which can be improved.

  Hereinafter, the best embodiment in the planting sheet of this invention is described based on drawing.

  FIG. 1 (A) shows a planting sheet according to the first embodiment of the present invention.

  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.

  A plurality of seeds 18 and a plurality of water retention agents 20 are dispersed and arranged between the two cut sheets 14 and 16, and these are adhered to the surfaces of the cut sheets 14 and 16 with an adhesive (not shown). Yes. In the present embodiment, the number of water retaining agents 20 is smaller than the number of seeds 18, but is not limited to this configuration, and the number of water retaining agents 20 and seeds 18 may be the same or the number of water retaining agents 20 may be large. Absent.

  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 seed 18, a plant seed coated with a mud component is used. In addition, you may use the seed which does not coat a mud component. In the present embodiment, a seed of daikandora (also referred to as dikondra, a perennial seed of the convolvulaceae) that is difficult to germinate is used as the seed 18.

  In the present embodiment, the plurality of seeds 18 and the plurality of water retention agents 20 are randomly arranged, but may be arranged at almost 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.

  Such a planting sheet 10 is obtained by spraying an adhesive onto a cut sheet 14 having a mesh-like cut 12 and dispersing and bonding a plurality of seeds 18 and dispersing a plurality of water retention agents 20. Glue. Then, the planting sheet 10 is completed by sticking the cut sheet 16 of the substantially same dimension on the surface to which the adhesive agent of the cut sheet 14 was apply | coated. 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 1st Embodiment of this invention is demonstrated.

  As shown in FIG. 2, when the user pulls both ends of the planting sheet 10 in a direction perpendicular to the direction of the notch 12 (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. 3, the planting sheet 10 is placed on the soil 2 that is a planting place by the user's hand, and the planting sheet 10 is pushed into the soil 2 by pushing it 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. 2, the seed 18 and the water retaining agent 20 are fixed (adhered) with an adhesive, so that the seed 18 and the water retaining agent 20 are inserted between the notches 12. Can prevent falling. 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 seed 18 is promoted. There is also an advantage of easy germination.

  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, sowing of the plurality of seeds 18 on the soil 2 is completed. At this time, it is not necessary to irrigate the newly covered soil 4.

  As shown in FIG. 4C, after seeds 18 are sown and after about one day at a temperature of about 20 ° C., a plurality of seeds 18 root and roots 22 come out. 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), after seeds 18 have rooted, after a week to 10 days at a temperature of about 20 ° C., a plurality of seeds 18 germinate and buds 24 appear. 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, sufficient water is supplied to the seeds 18 from the water-retaining agent 20 that has absorbed moisture and rain in the soil even after a small amount of rain after the seeds 18 are sown and the drying period continues. Therefore, the seed 18 is less likely to dry and die after rooting. For this reason, even if it is the seed 18 which is hard to germinate, germination probability can be improved remarkably. Moreover, even when it is difficult to regularly flood water in public works such as roads and parks, the germination probability of the seeds 18 can be improved and vegetation can be easily performed, and management becomes easy. In addition, by extending the planting sheet 10 and inserting it into the soil 2, it is possible to reduce the burden of seeding the seed 18 on a wide range of soil 2 and reduce the work load. Moreover, since this planting sheet | seat 10 can be used even if 3 to 4 years pass after manufacture, it can preserve | save easily and can respond to a demand rapidly.

  Next, the planting method using the planting sheet which is 2nd Embodiment of this invention is demonstrated.

  In addition, the same code | symbol is attached | subjected to the member same as 1st Embodiment, and the overlapping description is abbreviate | omitted.

  As shown in FIG. 5 (A), in the planting method of the present embodiment, a flower bulb 28 is planted between a plurality of planting sheets 10 sown in the soil 2, and the soil 4 is covered so as to cover the upper part thereof. Put on. When the seeds 18 are daikandora, a large flower does not bloom, so this is an effective planting method when it is desired to plant flowers between green grasses (daikandora). In the present embodiment, as the bulb 28, for example, seisei narcissus or the like is used. Further, instead of the bulb 28, a flower seed may be planted.

  As shown in FIG. 5 (B), buds 24 come out after roots 22 emerge from seeds 18 of planting sheet 10. At the same time, the bud 32 comes out from the bulb 28 after the root 30 comes out. Thereafter, as the buds 24 and 32 grow, the flower of the bulb 28 blooms between the green grasses, so that it can be planted with good appearance. Such a planting method can be suitably used when planting flowers in the center or side of a road, a park, or the like.

  In such a planting method, seeds 18 such as daikandora can be grown with little need for flooding management, weeds can be suppressed, and flowers can be bloomed by bulbs 28. For this reason, it is possible to plant with good appearance, reduce the work burden and management burden at the time of sowing, and reduce the maintenance cost.

  Moreover, as shown in FIG. 6, a plurality of bulbs 34 may be planted in the soil 2 at a predetermined interval, and the planting sheet 10 may be planted thereon. When the bud 32 that has come out from the bulb 34 grows, the shoot 32 further grows by breaking through the notch 12 portion of the cut sheets 14 and 16 made of paper. Moreover, there exists an advantage that water can fully be supplied also at the time of germination of the bulb 34 by increasing the quantity of the water retention agent 20 of the planting sheet 10.

  In addition, although the planting sheet 10 of 1st and 2nd embodiment was a dimension a little larger than a user's palm, this invention is not limited to this structure. For example, by forming a planting sheet in a large area, stretching it, laying it on the soil 2 and planting it, it is possible to sow the soil 2 over a wide area, and the work burden on the user can be further reduced.

  In addition, in the planting sheet 10 of the said embodiment, although the seed 18 and the water retention agent 20 are hold | maintained between the cut sheets 14 and 16, you may hold | maintain a fertilizer component, an insecticidal component, etc. in addition to these. 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 the said embodiment, although the mesh-shaped cut 12 cut | disconnected linearly 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.
