Description

Mat for Growing Glass Seeds and Fabricating Method

The present invention relates to a grass mat which is suitable for stabilizing the germination of grass seeds and the growth of early hair growth, while also making the seeding of the grass seeds easy to carry out.

Ordinary grass seeds can be germinated stably only when the surface layer and the upper surface of the ground maintain proper temperature and proper humidity, and furthermore, the initial hair growth at which the grass seeds germinate can be stabilized only when the ground layer and the upper surface of the ground layer maintain the proper temperature and humidity. Can be grown. In addition, in the case of turf transplanted in the form of a gut, the roots damaged during transplantation are not regenerated and die. Thus, the transplanted grass can survive only when new roots are grown. New roots will only occur in nodes of Rhizome, stolon and upright stems. For rooting of new roots at the time of transplantation of the grass, the surface layer and the surface surface must maintain the proper temperature and appropriate humidity. In the case of wild grass in Korea, the optimum temperature for germination of seeds is about 26 ° C to 35 ° C, and the optimum temperature for root growth and underground growth is about 25 ° C to 30 ° C. In view of this, grass seed germination requires a high temperature of about 35 ° C. during the day and about 20 ° C. at night, which must be maintained for about 6 to 7 weeks for stable growth of the initial hair growth. .

Typically, the sowing time of the grass seeds is usually carried out from spring to summer. Of these, spring sowing is carried out at a time when the surface layer, i.e. approximately 5 cm of ground temperature from the ground surface, is at least 14 ° C. In the central region, spring sowing will be possible after approximately April 15. Next, summer sowing should be carried out 30 days before the average temperature drops to 20 ° C. As such, sowing of grass seeds is carried out at a time when the temperature of the ground layer and the ground surface is lower than the temperature necessary for the germination of grass seeds and the growth of early seedlings.

Grass seeds are sown mainly by a sowing method called "hydroydding". According to the hydro seeding method, the grass seeds are sprayed onto the ground to be sown in a state of being mixed with a fiber solution in a liquefied state. In order for these seeded grass seeds to germinate normally, moisture must be properly maintained in the surface soil. To provide adequate moisture to the soil, continuous watering must be involved. Grass seeds sown on the slopes flow along the slope due to the phenomenon of clavicle on the surface during watering and rainfall, so that the grass seeds are concentrated in some areas of the surface. As a result, turf seeds cannot be germinated uniformly.

In order to keep warm and moisturize the grass seed sown, a vinyl sheet is covered on the upper part of the seeding ground. In other words, the vinyl sheets are covered on the ground on which the grass seeds are sown, in order to maintain the temperature of the surface layer and the surface over which the grass seeds are sown, at a temperature of 26 ° C. to 35 ° C., as well as to provide adequate moisture to the grass seeds. . The vinyl sheet maintains the space between the surface of the earth and the surface layer temperature at about 35 ° C even when the outside air temperature is about 20 to 30 ° C. The temperature of the space is raised to about 65 to 70 ℃. As a result, the temperature of the space between the ground surface and the vinyl sheet and the temperature of the surface layer rise, resulting in long, soft growth or sunburn. In order to prevent this, a drilling operation for forming the ventilation holes in the vinyl sheet is performed in stages. This drilling work performed by manpower not only imposes a separate maintenance fee on the grass producer, but also causes irregularities in size and spacing of the ventilation holes. Irregularly formed ventilation holes prevent moisture from being uniformly absorbed by the grass seeds during watering and rainfall, and when the ventilation holes are large, the vinyl sheet is torn and blown off due to an unbalanced amount of wind. As a result, in the vinyl sheet method, it was difficult to ensure stable germination of grass seeds and stable growth of early seedlings.

Alternatively, a giant may be covered on top of the sown seed. The covered grass on top of the grass seeds provides some warming and moisturizing effects, but has the disadvantage that grass seeds sown on slopes cannot be prevented from flowing by watering and rainfall. As a result, grass seeds cannot be germinated stably and uniformly, and early seedlings are concentrated locally.

In this view, a new type of vinyl film is desired that is suitable for promoting stable germination of grass seeds and growth of early seedlings. In addition, there is a need for a new grass germination seed mat that facilitates stable seeding of grass seeds and growth of early seedlings, and even sowing of grass seeds.

Accordingly, it is an object of the present invention to provide a seed mat for lawn germination and a method for producing the same, which promotes stable germination of grass seeds and growth of early seedlings and facilitates sowing of grass seeds.

Another object of the present invention is to provide a seed mat for lawn germination having a selective herbicide suitable for inhibiting germination and growth of weeds.

In order to achieve the above object, the seed mat for grass germination according to the present invention is formed of any one of fibers, coconut dust and paper sludge, and the temperature and humidity of the ground color layer and the vegetation ground layer surface layer on which seeds are sprayed on one surface. To ensure that the ventilation holes of a certain size are formed at regular intervals and to have a vinyl sheet located on the other side of the green ground layer and a layer of protective material provided on the ground of the green ground where the grass seeds are sprayed. It features.

Method for producing a seed mat for grass germination according to the present invention comprises the steps of providing a vinyl sheet having ventilation holes formed, and applying any one of fibers, coconut dust and paper sludge to the surface of the vinyl sheet to form a vegetation ground layer And spraying the grass seeds onto the surface of the vegetation ground layer, and forming a layer of protective material on top of the vegetation ground layer to which the grass seeds have been sprayed.

Other objects and advantages of the present invention in addition to the above objects will become apparent from the detailed description of the embodiments with reference to the accompanying drawings.

Hereinafter, with reference to Figures 1 to 4 attached to a preferred embodiment of the present invention will be described in detail.

1 shows a grass germination film with a vinyl sheet 10. The vinyl sheet 10 may be a transparent resin having good light transmittance, and preferably made of agricultural polyethylene sheet. In addition, the vinyl sheet 10 may be formed to have a thickness of 0.03 mm, but when the grass germination film is used in a windy area, the vinyl sheet may be formed to a thickness of 0.04 mm.

In the vinyl sheet 10, the ventilation holes 11 are formed in the vinyl sheet 10 at any size and at any interval. The ventilation hole 11 may be formed to have a diameter of about 8 to 10 mm, but is preferably formed to have a diameter of 9 mm. In addition, the ventilation holes 11 may be formed at intervals of about 3 to 5 cm depending on the size and sowing, but when the grass seeds are sown in the spring and the grass seeds are sown in the summer In this case, it is preferably formed at intervals of 3.5cm. The size of this ventilation hole 11 and the spacing between the ventilation holes 11 are clearly confirmed through Tables 1 to 3 obtained through the test. Table 1 shows the germination patterns of the grass seeds when the vinyl sheet 10 in which the ventilation holes 11 of 8, 9 and 10 mm are formed is left standing on the seeding ground of the grass seeds, respectively. Referring to Table 1, 8mm The vinyl sheet 10 in which the ventilation holes 11 of the diameter are formed causes the temperature near the ground surface where the grass seeds are sown to be erased so that some of the grass seeds and initial seedlings are wiped out. On the other hand, the vinyl sheet 10 having the 9 mm or 10 mm diameter ventilation holes 11 formed therein has a low humidity near the ground where the grass seeds are sown, so that the germination of the grass seeds becomes poor or the growth of the initial seedlings is poor. . Further, when the vinyl sheet 10 having the diameter of the ventilation hole 11 is 10 mm is used rather than the vinyl sheet 10 having the diameter 11 of the ventilation hole 11, the germination of grass seeds and the growth of initial seedlings are worse. Done. In addition, the vinyl sheets 10 having the diameter of the ventilation hole 11 formed to be smaller than 7 mm increase the temperature near the ground surface so that the grass seed and the initial seedlings are deepened. On the contrary, the vinyl sheets 10 having the diameter of the ventilation holes 11 formed to be larger than 11 mm excessively drop the humidity near the ground surface, so that the germination and early seedling growth of the grass seeds become even worse. In view of this, it is preferable that the ventilation holes 11 having a diameter of 9 mm are formed in the vinyl sheet 10.

TABLE 1

Table 2 shows the germination state of the grass seeds according to the distance between the ventilation holes (11). In Table 2, when the interval between the ventilation holes 11 is 5 × 5 cm or more, the moisturizing power is good, but high temperature damage occurs, so that a weak initial seedling phenomenon occurs. On the other hand, when the spacing between the ventilation holes 11 is 3 × 3 cm or less, the air permeability is good, but the moisturizing power is poor, the poor germination of grass seeds appear.

TABLE 2

Table 3 shows the germination and growth of early seedlings of grass seeds while varying the diameters of the ventilation holes 11 formed in the vinyl sheet 10 and the intervals between the ventilation holes 11 and the seeding time of the grass seeds. The test results are explained. It can be seen from Table 3 that the diameter of the ventilation hole 11 is preferably 9 mm. Further, it can be seen that the spacing between the ventilation holes 11 is preferably 4.5 cm for spring sowing and 3.5 cm for summer sowing.

TABLE 3

The grass germination film in which the ventilation holes of a constant size are formed at appropriate intervals improves breathability by the ventilation holes and also uniformly supplies water to the grass seeds by suppressing moisture evaporation of the soil. In addition, the grass germination film properly maintains the temperature and humidity at the ground layer and the ground surface to which the grass seeds are sown. By the grass germination film, not only the germination of the grass seed proceeds stably, but also the growth of the initial seedling is stabilized. In addition, the grass germination film is not torn by the wind due to the ventilation holes are used as a vent and further enables construction on a windy day. In addition, the grass germination film prevents the soil from being lost so that the germination of the grass seeds sown on the slope and the growth of the initial seedlings that are germinated proceed stably.

Figure 2 schematically shows a seed mat for grass germination according to an embodiment of the present invention. In Fig. 2, the seed mat for grass germination has a uniform shape on the lower surface of the vegetation ground layer 24 and the adhesive material layer 22 and vegetation ground layer 24 formed sequentially on the lower surface of the vinyl sheet 20. With sown grass seeds 26. The vinyl sheet 20 is formed with ventilation holes 11 as described in FIG. 1. The vinyl sheet 20 is formed of polyethylene having a thickness of approximately 0.03 to 0.04 mm. The adhesive material layer 22 adheres the vegetation ground layer 24 and some of the grass seeds 26 to the bottom surface of the vinyl sheet 20. The adhesive material layer 22 is formed by an adhesive which is dissolved by the water part and which is not toxic. Adhesives for forming the adhesive material layer 22 include polymers containing about 10% of ester groups so that acetate groups are substituted by hydroxyl groups and readily dissolved by moisture. Will be used.

The vegetation ground layer 24 is warmed and moisturized for stable germination of the grass seeds 26 and also allows the grass seeds 26 to stably stick to the soil. To this end, the vegetation ground layer 24 is formed by fibers, coconut dust or paper sludge that are easily decomposed and reduced by soil microorganisms. In detail, the vegetation ground layer 24 is formed by applying a solution in which fiber, coconut dust or paper sludge is dissolved onto the vinyl sheet 20. On the other hand, the grass seeds 26 are sown on the lower surface of the vegetation ground layer 24 at regular intervals. Alternatively, the grass seeds 26 may be sown by spraying with fiber, coconut dust or paper sludge solution.

In addition, the seed germination mat according to the embodiment of the present invention further includes a protective material layer 28 formed on the lower surface of the vegetation ground layer 24 on which the grass seeds 26 are sprayed. Protective material layer 28 will protect vegetation ground layer 24 and turf seed 26. In detail, the protective material 28 is adhered to some of the vegetation ground layer 24 and the grass seeds 26 to prevent loss of the vegetation ground layer 24 and the grass seeds. In addition, the protective material layer 28 should be formed of an adhesive that is not toxic while the adhesive material layer 22 is dissolved by moisture. The adhesive forming the protective material layer 28 is preferably the same as the adhesive forming the adhesive material layer 22 described above.

The grass seed germination mat of this structure facilitates stable germination of grass seeds and growth of early seedlings, as well as facilitates sowing of the grass seeds and further reduces the seeding time and costs of the grass seeds. In addition, the grass germination seed mat may evenly stabilize the seeding of the grass seed on the inclined surface and promote the stable germination of the grass seed on the inclined surface and the growth of early seedlings.

Figure 3 schematically shows a seed mat for grass germination according to another embodiment of the present invention. The grass germination seed mat of FIG. 3 is similar to the grass germination seed mat shown in FIG. 2, but in FIG. 2 between the lower surface of the vegetation ground layer 24 sprayed with the grass seeds 26 and the protective material layer 28. The difference is that it further comprises a herbicide layer 30 formed on. The herbicide layer 30 is formed by a selective herbicide to suppress germination and growth of weeds except for Korean grass. To this end, the herbicide layer 30 is formed to contain a selective herbicide, such as Tuper San, about 1.2 to 2.09 per square meter. In other words, herbicide layer 30 will comprise a selective herbicide at a concentration of 1.2 to 2.09 g / m 2. In addition, the herbicide layer 30 may be integrally formed with the adhesive material layer 22 or the protective material layer 28 by applying the selective herbicide together with the adhesive to form the adhesive material layer 22 or the protective material layer 28. It may be formed as.

As the vinyl sheet 20 proceeds from the sheet roll 40 toward the rollers 42, the adhesive sheet 41, vegetation material 43, grass seed 26, herbicide 45 on the surface of the vinyl sheet 20. ) And the protective material 47 are sequentially sprayed. As a result, the adhesive sheet layer 22, the vegetation ground layer 24 sprayed with grass seeds, the herbicide layer 30 and the protective material layer 28 are sequentially formed on the surface of the vinyl sheet 20 reaching the roller 42. To be stacked. The adhesive amorphous layer 22 is formed by applying the adhesive material 41 such as PVA to the surface of the vinyl sheet 20 in a state of being dissolved in water. The vegetation ground layer 24 is formed by spraying or applying on top of the adhesive material layer 22 while dissolved in water such as fibers, coconut dust or paper sludge, which are easily decomposed by soil microorganisms. Grass seeds 26 are sprayed at regular intervals on the surface of the vegetation ground layer 24 thus formed. In addition, the herbicide layer 30 is formed on the surface of the vegetation ground layer 24 to which the grass seeds 26 are sprayed by spraying or applying a selective herbicide 45 such as tuper sand dissolved in water. Further, the protective material layer 28 is formed on the herbicide layer 30 by applying a protective material made of the same adhesive as the above-described adhesive material dissolved in water. Here, the herbicide layer 30 may be applied on top of the vinyl sheet 20 in a state of being mixed with an adhesive material and / or a protective material. In this case, the herbicide layer 30 is integrated with the adhesive material layer 22 and / or the protective material layer 28.

The adhesive material layer 22, the vegetation ground layer 24, the herbicide layer 30, and the protective material layer 28, which are sequentially formed on the vinyl sheet 20, reach the first heater before reaching the rollers 42. By 46, it is made to dry at the temperature of 50 degrees C or less. The adhesive material layer 22, vegetation ground layer 24, herbicide layer 30 and protective material layer 28 on the vinyl sheet 20 thus dried are pressurized to a constant thickness by the roller 42. The grass germination seed mat is pressurized and dried by the second heater 48. The second germ seed germination mat is the moisture content of the grass germination seed mat. Finally, the mat roll 44 winds the grass germination seed mat dried by the second heater 48 in the form of a roll.

Next, a grass seeding method for seeding grass seeds using the grass germination seed mat manufactured in the above-described form will be described. The first step in the sowing method of the grass seed is to stop, pick out the impurities such as stones, tree roots, etc. present at the place of sowing and then level the ground. Subsequently, the ground is put down by the rollers so that the grass germination seed mat is easily attached to the ground. On the ground to be suppressed, the seed mat for lawn germination as shown in FIG. 2 or FIG. 3 is installed. At this time, the grass seed is directed to the ground and the grass mats so that the seed mats for grass germination close to each other. Allow some water to be sprayed on top of the installed grass germination seed mat. In this way, water is sprayed after the seed germination mat is installed so that the seed germination mat is brought into close contact with the ground. In this way, it is not necessary to apply cover to the ground where the grass seeds are sown, and only the fixing work of the grass seed germination mat is performed by landing pins being picked up at regular intervals, for example, 2 m intervals. It is preferable that an operator who performs the above-mentioned stopping operation, laying of the seed mat for lawn germination, spraying water and landing pin operation wears sneakers with a flat bottom.

Next, when sowing seeds with different seeding times using the grass germination seed mat according to the present invention and when sowing seeds with different seeding times, and sowing grass seeds using a conventional vinyl sheet. The germination patterns in the case of different sowing will be examined through Table 4. The results of Table 4 show that in 1997, the grass seed with 80% germination was scattered about 10g per square meter on the ground and left for 9 weeks in the natural neglect state at the experimental farm located at 1106, Samheung-ri, Ganghwa-gun, Incheon, Korea. It shows the ground yield rate due to the growing residue.

TABLE 4

In Table 4, when only the grass seeds are sown, the grass seeds germinate and grow poorly due to drying, and the grass seeds sown by the method using conventional vinyl sheets may have poor germination due to high temperature and drying. In addition, it can be seen that the early seedlings are killed by the damage. On the contrary, the germination of the grass seeds seeded by the grass germination seed mat of the present invention is stabilized, and the growth of the initial seedlings is also stabilized. As a result, the ground on which the grass seeds are sown by the grass germination seed mat of the present invention is covered with an average of 85% by the grass.

As described above, the grass germination seed mat according to the present invention has a vegetation ground layer formed on the vinyl sheet on which the ventilation holes are formed, and the grass seeds are sprayed on the surface of the vegetation ground layer, thereby ensuring stable germination and initial growth of the grass seeds. It not only stabilizes the growth of seedlings, but also facilitates sowing of the grass seeds and further greatly reduces the seeding time and costs of the grass seeds. In addition, the grass germination seed mat may stabilize the seeding of the grass seeds on the inclined surface and stabilize the germination of the grass seeds on the inclined surface and the growth of early seedlings. Further, the herbicide layer 30 is formed of a herbicide layer of selective herbicide on the vegetation ground layer to which grass seeds have been sprayed, thereby suppressing germination and growth of weeds and further promoting the germination and early seedling growth of grass seeds. Let's go.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
