Description

  The present invention relates to vegetation revegetation that combines a weed control and a revegetation sheet for landscape greening such as road separation zones and slopes.

  Weeds that grow on road separation zones and slopes have high plant heights, poor visibility, hinder traffic safety, and adversely affect the surrounding landscape. It was. Therefore, in recent years, a surface protection layer selected from the inorganic particles of Patent Document 1 and synthetic resins containing inorganic particles, a modified asphalt layer, and a herbicidal sheet in which at least three layers of a base material layer are laminated, and these three layers have been modified. Weeds do not grow by weeding and fixing a weed-proof sheet with at least 5 layers of a porous asphalt layer and a back surface layer selected from synthetic resin, rubber, inorganic particles and synthetic resin containing inorganic particles. Attempts have been made to do so.

  In Patent Document 2, the first layer is a non-woven fabric having water repellency, the second layer is a herbicidal greening sheet based on a structure in which seeds are held between nonwoven fabrics having water permeability and water retention. Is a sheet that allows plant buds to pass through but does not allow moisture to stay on the surface, and has the effect of inhibiting the rooting of flying seeds. Attempts have been made by a greening method that aims at greening and weed control with a sheet integrated with a sheet that sucks up the surface moisture and reaches the seeds.

  However, although weed control with a weed control sheet in Patent Document 1 does not grow weeds, only one bare weed control sheet spreads and the deterioration of the local landscape is becoming a problem. Further, in Patent Document 2 which aims at greening and weed control, the first layer sheet is required to inhibit the rooting of flying seeds, but it is not possible to completely suppress weed invasion with a sheet through which vegetation is passed. It is possible, and it is a mechanism that supplies moisture to the seeds by capillary phenomenon from the ground surface in the second layer sheet, but it is possible when moisture remains on the ground surface, but a sheet having water repellency is used on the surface However, it is difficult to legally supply sufficient moisture to the ground surface of the laying surface.

  In order to solve the above-mentioned problems, the present invention is difficult to break or corrode, has an excellent herbicidal effect, does not interfere with the local landscape and traffic visibility, and can be easily constructed with a light weight that allows desired plants to grow for a long period of time. It is to provide a seeded herbicidal sheet that also has a herbicidal sheet.

  Therefore, in order to control the weeds at the installation location and form a sheet that can allow the desired plants to grow, a black non-woven fabric that has water retention without passing through the buds of plants in order from the bottom, black policy that does not allow roots and water to pass G. A black non-woven fabric with water repellency and root resistance is stacked to form a single herbicidal sheet by thermal bonding, and numerous through-holes with a diameter of several tens of millimeters are formed on the surface of the herbicidal sheet at regular intervals. A perforated weedproof sheet. Underneath the black nonwoven fabric surface having water retention, which is the lower surface of the grass-proof sheet with through-holes, a black raschel net of about 2 mm that suppresses the growth of weeds from the through-holes is protected by a water-soluble sheet underneath. The seed sheets are arranged in order, and heat-bonded so that the sheets are integrated to form a single herbicidal sheet with seeds.

  Lay the seed-proof herbicidal sheet on the construction site such as a separation zone where weeding work has been conventionally performed without gaps with the seed sheet surface as the lower surface, and place and fix it using a large head pin with a large head, and with seeds A greening method using a seeded herbicidal sheet capable of growing a desired plant seed by blocking the weed growth from the gap, etc., by closing the gap between the peripheral surfaces where the herbicidal sheet is in contact with the structure with a sealing agent.

  After laying, the planting method using the herbicidal sheet with seeds, which is fixed with a large head pin and closed around the edge with a sealing agent, suppresses the growth of weeds at the installation site, and allows the desired plant to grow and prosper from the through hole. It becomes possible, and we can plan tree planting such as road and slope which need weed management and improvement of local scenery.

  In addition, the seeds included in the seeded grass protection sheet to be laid shall be a short-stem-type short grass species that does not require mowing (for example, Takii seedlings centipede grastef blair, wild grass, Bermuda grass, etc.) The grass seeds germinated under the weed control sheet eventually grows like a runner from the through-hole on the seeded weed control sheet to form a dense grassland on the sheet, further preventing weeds from entering. Reduction of weeding costs and improvement of road traffic vision.

  In addition, the seeded herbicidal sheet made of a material that does not corrode easily is lightweight and easy to construct, and also ensures durability, heat retention by multiple sheets and suppression of moisture evaporation, and the water retention period is long. Since it can ensure migration, it is also a herbicidal sheet with seeds that enables the desired plant to grow for a long time only by natural rainfall.

It is explanatory drawing which shows the structure of the weed control part of the weed control sheet with seeds. It is explanatory drawing which forms a through-hole in a herbicidal sheet with a seed. It is explanatory drawing which shows a herbicidal sheet | seat with a seed. It is explanatory drawing which lays and fixes the seed-proof grass prevention sheet | seat.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an explanatory view showing the structure of the weed control part of the seeded weed control sheet. The sheets forming the grass-proofing part are all lightweight, non-damaged and corroded, and hardly transmit light. From the bottom, the black nonwoven fabric 1a, which has rayon properties and does not pass through plant buds, has water retention, Then, a black polysheet 2 that does not allow water to pass through and a polyester black nonwoven fabric 1b having water repellency and root resistance are stacked in this order to form one sheet of grassproof sheet 3 that does not allow light to pass through by thermal bonding.

FIG. 2 shows a double-sided pressure-sensitive adhesive tape 6 for joining the herbicidal sheets on one side of the surface of the herbicidal sheet 3 formed as described above. Through holes 4 having a diameter of 10 mm are arranged at intervals of 20 mm in length and width so as to be able to extend on the sheet from the bottom of the herbicidal sheet 3, a black surface having a water repellent black nonwoven fabric and a water repellent bottom surface. Let it be the weed prevention sheet 7 with a through-hole formed with a nonwoven fabric. In addition, the area of the through-hole which occupies for a grass prevention sheet | seat is about 9%, and a non-pore ratio becomes 91%. In addition, by forming an adhesive tape on the surface of the weedproof sheet, it can be laid without creating a gap between the weedproof sheet and the weedproof sheet without being blown by the wind.

  FIG. 3 shows a 2 mm-thick polyethylene black russell that prevents existing weeds from penetrating and growing on the bottom surface of the weed control sheet 7 with through holes formed in FIG. A net sheet 8 is placed underneath, and a seed sheet 9 containing a stalk-type short grass seed and fertilizer is placed on a water-soluble paper sheet, and heat-bonded so that each sheet is integrated to prevent the seed from being attached. The grass sheet 10 is used. Since the seed sheet 9 has a property of being dissolved when it absorbs moisture, the seed sheet 9 is dissolved by moisture on the ground surface, moisture from the through-holes, etc., and the encapsulated seed comes into direct contact with the ground surface and absorbs moisture to germinate and grow.

  FIG. 4 is a cross-sectional view of a seeded grass protection sheet laid. Weed and fix the seed-proof grass sheet on the road separation zone and slope where weeds grew and weeding work was done. Since the installation does not create a gap between the seeded grass-proof sheet and the laying surface, the grounding surface and seeded grass-proof sheet 10 are brought into close contact with each other after cutting the weeds, and the adhesive portions are overlapped to attach the double-sided adhesive. Adhesive with tape and repeat this work to cover the entire laying area to make a single herbicidal sheet with seeds. In order to prevent weed growth from the side surface of the anchor pin, the large-head anchor pin 11 having a head wider than the thickness of the anchor pin use.

  A sealing agent 13 is used to seal the gap between the seeded weedproof sheet 10 and the curbstone 12 so that weeds do not grow from the gap between the curbstone 12 such as a concrete block in contact with the periphery of the seeded grassproof sheet 10 laid and fixed at the installation location. The seeded weedproof sheet 10 is laid and fixed so that no weed grows from the installation surface of the seeded weedproof sheet.

  The herbicidal sheet with seeds is formed of a black sheet other than the sheet with seeds, and the through-holes occupy about 9% of the sheet area and the non-porous part is about 91%. The light does not reach and the weeds do not grow, and the through-holes formed in the sheet surface are covered with a 2 mm mesh raschel net sheet, so that the growth of existing weeds is suppressed and the ground surface Weeds do not grow. In addition, the seeds of the chewing stem type contained in the herbicidal sheet with seeds, when placed on the laying surface, the surface moisture and temperature are maintained and the seeds germinate at an early stage. It grows on the seeded herbicidal sheet from the through-hole through the mesh, and eventually grows while running as a runner to cover the sheet surface.

  The seed-proof grass-proof sheet is a sheet that combines grass and vegetation that suppresses the growth of weeds and grows the desired grass species, is lightweight and easy to construct, and is resistant to breakage and corrosion. The body can be maintained, and it is highly likely to be used as a greening material for roads and slopes where weed management is necessary, and as a greening material for restoring the natural environment in landscape formation.
