Description

  The present invention relates to a lawn growing method.

  2. Description of the Related Art In recent years, lawn cultivation in sports facilities such as golf courses and soccer fields and lawn cultivation for the purpose of greening on school yard and building rooftops have been actively performed.

  This lawn can be cultivated by sowing the turf seeds in the soil that will be the construction site, or by raising the turf seeds to seedlings in a different place from the construction site, It is common to use a lawn turf method.

  However, lawn growing is particularly difficult in winter when the temperature (temperature and ground temperature) at the construction site is low, and in summer when the temperature (temperature and ground temperature) is high (the period between December and March is soil). This is because the soil temperature is drastically lowered and the soil temperature drops drastically, and the soil in April to June tends to be deficient due to evaporation of soil moisture.) The current situation is that no lawn growing method has been established. This problem becomes more prominent as the construction area increases.

  As a result of various experiments and researches focusing on the above-mentioned problems, the present inventor has developed an unprecedented innovative lawn growing method.

  The gist of the present invention will be described with reference to the accompanying drawings.

The seedlings 1a are sown on the soil E, and then the soil 7 is applied so that the turf seedlings 1a are hidden and fertilizer is provided on the joints 7, and the seeds 1b are seeded on the joints 7, and then the eyes A recess 9 is formed in the soil 7, and then, the area where the turf seedling 1 a and the turf seed 1 b are spread is covered with the following sheet material 3 in which a plurality of through holes 2 are scattered, and the periphery of the sheet material 3 The method relates to a lawn growing method characterized by fixing a part to the soil E.
Record
The sheet material 3 is selected from a plurality of sheet materials prepared by varying the scattered density of the through-holes 2 in accordance with temperature conditions such as air temperature and ground temperature at a construction site, and each of the sheets The material 3 is light transmissive.

  The lawn growing method according to claim 1, wherein the dent portion 9 is formed by running a buggy tire 8 on the joint soil 7.

  Further, in the lawn growing method according to any one of claims 1 and 2, the sheet material 3 is fixed to the soil E by a fixing nail 5 stabbed in a peripheral portion of the sheet material 3. It relates to the lawn growing method.

  Further, in the lawn growing method according to any one of claims 1 to 3, a region where the lawn seedling 1a and the lawn seed 1b are spread is covered with a plurality of the sheet materials 3, and the adjacent sheet materials 3 are arranged. The end portions of the turf are in an overlapping state, which is related to a lawn growing method.

  Since the present invention is configured as described above, it is an unprecedented and innovative lawn growing method capable of easily and reliably growing lawn according to the natural environment.

  DESCRIPTION OF EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the drawings showing the operation of the present invention.

  A lawn material 1 such as a lawn seed or a lawn seedling is provided on the soil E, and a region where the lawn material 1 is provided is covered with a sheet material 3 in which a plurality of through holes 2 are scattered.

  In the present invention, the sheet material 3 always provides an environment suitable for lawn growing, for example, even in the season when lawn growing is difficult, and easily and reliably grows a good lawn according to the natural environment. can do.

  When the area where the turf material 1 is covered with this sheet material 3 is grown in the cold time, the sheet material 3 exhibits a heat blocking function so that the heat released from the soil E is not dissipated and grows the lawn. The necessary temperature is maintained.

  Further, the sheet material 3 has a function of discharging unnecessary moisture to the outside from a plurality of vent holes 2 while holding necessary moisture, and harmful gas generated from the soil E (obstructing lawn growth). Gas) and fresh air from the outside is taken in, and the function of replacing the air is also exhibited, and an environment suitable for lawn cultivation is obtained.

  On the other hand, if the sheet material 3 is covered with the sheet material 3 and grown in a period when the temperature is relatively high and the amount of rainfall is low, the sheet material 3 receives moisture evaporated from the soil E and grows the lawn. Moisture retention function is demonstrated so that necessary moisture is not dissipated (moisture tends to be insufficient during hot season), and moisture necessary for grass cultivation is secured.

  In addition, the heat released from the soil E from the plurality of air holes 2 provided in the sheet material 3 is discharged to the outside, and harmful gas generated from the soil E (gas that hinders grass growth) is discharged to the outside. It will also demonstrate the function of replacing fresh air with the environment, and an environment suitable for lawn cultivation will be obtained.

  The inventor has confirmed this point through experiments.

  Accordingly, an environment suitable for lawn cultivation is always obtained, and a good quality lawn can be cultivated easily and reliably according to the natural environment, and the lawn can be cultivated in a stable environment. Lawn can be nurtured quickly, and watering and other work can be reduced, leading to excellent cost.

  In addition, the present invention can surely prevent the grass material 1 spread on the soil E by the sheet material 3 from moving due to wind and rain, and can grow a uniform lawn without unevenness.

  In addition, according to the present invention, by appropriately using the sheet material 3 having different scattered density of the through holes 2 according to the temperature conditions such as the air temperature and the ground temperature at the construction site, an environment suitable for growing lawn according to the natural environment can be obtained. Will be obtained.

  That is, for example, as the sheet material 3 used in a relatively cold time, the sheet material 3 having a coarser density of the through holes 2 (the interval between the through holes 2 is wider) than the sheet material 3 used in a hot time to be described later. When used, the heat retaining function is exhibited as much as that. On the other hand, for example, as the sheet material 3 used in a relatively hot time, the scattered density of the through holes 2 is higher than that of the sheet material 3 used in the cold time described above. When using a fine sheet material 3 (where the interval between the through holes 2 is narrow), the function of preventing moisture from evaporating from the soil E and preventing the inside of the sheet material 3 from being steamed due to good air permeability. (Excessive moisture will adversely affect lawn cultivation.)

  Further, in the present invention, when the light transmissive sheet material 3 is adopted as the sheet material 3, the light necessary for growing the lawn can be taken in, and the lawn growing degree can be confirmed by using the sheet material 3 as well. This can be done reliably in the coated state.

  Specific embodiments of the present invention will be described with reference to the drawings.

  In the present embodiment, a lawn G in which a lawn material 1 such as lawn seedling 1a or lawn seed 1b is sown on soil E, and a region where the lawn material 1 has been covered is covered with a sheet material 3 in which a plurality of through holes 2 are scattered. It is a training method. In addition, although a present Example is a case where the construction place which grows the lawn G is a golf course, it is not restricted to this, For example, if it is a place which can demonstrate the characteristic of a present Example, such as a schoolyard and the rooftop of a building Any place is fine.

  The sheet material 3 is formed of an appropriate transparent synthetic resin (polyethylene) as shown in FIGS. 1 and 2, and a plurality of through holes 2 are scattered on the surface.

  The through-hole 2 is a circular hole having a diameter of about 1.8 mm that exhibits air permeability and water permeability.

  In addition, as the sheet material 3, two types of sheet materials 3 having different scattered densities of the through holes 2 (intervals between the through holes 2 are different) are prepared. Specifically, the interval between the through holes 2 is a sheet material 3 having a narrow interval (fine scattering density) of about 0.6 mm to about 10 mm, and a wide interval of about 11 mm to 20 mm (coarse scattering density). ) Sheet material 3 is prepared. The interval between the through holes 2 that determines the fine and coarse scattered density of the through holes 2 is not limited to that described above, and can be set as appropriate as long as it is a value that exhibits the characteristics of the present embodiment.

These two types of sheet materials 3 are designed in consideration of the natural environment (air temperature and earth temperature) for cultivating the lawn G, and are properly used (the diameter of the through holes 2 is the same and the interval between the through holes 2 is different). The sheet material 3 used in the cold time and the sheet material 3 used in the hot temperature are properly used.)
That is, the sheet material 3 used when the temperature is cold (the sheet material 3 having the same diameter as the through-hole 2 but a wider interval between the through-holes 2 than the sheet material 3 used when the temperature is hot described later). ) On the other hand, in order to exert a sufficient heat retaining function, the scattered density of the through holes 2 is set to be coarse (the interval between the through holes 2 is wide). In order to facilitate the escape of moisture evaporating from the soil E, the through holes 2 have the same diameter as that of the sheet material 3 used in the cold season, but the interval between the through holes 2 is narrow. The scattered density of the through holes 2 is set to be finer (the interval between the through holes 2 is narrower) than that of the sheet material 3 for use. In the present embodiment, the scattered density of the through holes 2 provided in the sheet material 3 used in the cold time is 5 ° C. or more, while ensuring the moisture passing function necessary for growing the lawn G, It is set so as to exert a heat retaining function to the extent that it is kept warm.

  In addition, the lawn G has a cold region type turf grass and a warm region type turf grass. The growing temperature, which is used as a standard for warm-ground turfgrass (such as wild grass, mulberry grass, and bermudagrass), is about 25 ° C to 35 ° C.

  Therefore, the proper use of the sheet material 3 at this temperature is appropriately selected in consideration of the cold and hot periods depending on the cultivatable temperature of each plant. In the case of a cold region type turfgrass, the interval between the through holes 2 is selected. In the case of warm-ground turfgrass, a sheet material 3 having a narrow interval between the through holes 2 is used.

  A method for growing a lawn G in a golf course green using the sheet material 3 having the above configuration will be described with reference to FIGS. In the present embodiment, the sheet material 3 is described as being used in the sowing method, but it may be used in the sowing method, and both the sowing method and the sowing method in Example 2 described later. You may use when using together.

First, as shown in FIG. 3, about 2 m ² of bundled turf seedlings 1a (turf material 1) are loosened with water, and the separated turf seedlings 1a are separated into about 500 m ² of soil E (molded and leveled green). Surface). In addition, the bent grass (bent grass) is employ | adopted as the lawn G to grow.

  Subsequently, as shown in FIG. 4, the sand 6 is applied by the sand dust spreader to such an extent that the turf seedlings 1 a are hidden (not blown away by the wind), leveled by the rake, and sufficiently sprayed. If there is green undulation, move the mesh sand spreader from higher to lower.

  Subsequently, as shown in FIG. 5, the area where the seedlings 1 a are planted is covered in a state where a plurality of sheet materials 3 are arranged. As shown in FIG. 6, the sheet material 3 is fixed to the soil E by a fixing nail 5 pierced on the peripheral edge portion thereof, and ends of adjacent sheet materials 3 are overlapped and fixed by the fixing nail 5. .

  As described above, the sheet material 3 is used separately between the cold time sheet material 3 and the hot time sheet material 3 according to the season (temperature / ground temperature) as described above. In this case, the lawn G is bent grass, The sheet material 3 for a cold time is used.

  In the stage of covering the sheet material 3, the growing condition of the lawn G is managed by watering or observing the growth condition of the lawn G (the lawn G is lifted to lift the sheet material 3 as shown in FIG. 7). grow up).

  Subsequently, after confirming that the lawn G has grown sufficiently, the sheet material 3 is removed (see FIG. 8), and thereafter, as usual, watering, roller rolling, mowing, sand sand, fertilization, pest prevention action The lawn G is completely grown.

  The present inventor has confirmed that when the lawn G is grown by the growth method using the sheet material 3 described above, the high-quality lawn G can be reliably and inexpensively grown compared to the case where the sheet material 3 is not used. ing. This is presumably because the use of the sheet material 3 that exhibits the above-described functions makes it difficult to be affected by the temperature such as the air temperature or the earth temperature at the construction site, and a stable growing environment is obtained.

  In addition, the present inventor has confirmed from the following Experiment 1 and Experiment 2 that there is a difference in the growing condition of the lawn G due to the difference in the scattered density of the through holes 2 provided in the sheet material 3.

Experiment 1
Prepare two sheet materials 3 having different scattered density of the through-holes 2, and each of the two sheet materials 3 is described above in February when the temperature / ground temperature is cold (average temperature 3.3 ° C., average temperature 6.1 ° C.). The lawn G growing method according to this example was performed, and the sheet material 3 was removed and observed in April (average temperature 12.6 ° C., average ground temperature 13.2 ° C.). The lawn G in the region grown by covering the rough sheet material 3 with a wide gap (the interval between the through holes 2 is wide) extends to about 15 cm to 20 cm, while the through holes 2 have a small scattered density (the distance between the through holes 2). It was confirmed that the lawn G in the region grown by covering the growth with the sheet material 3 (with a narrow interval) caused poor growth at about 5 cm to 10 cm.

  Therefore, it can be said from Experiment 1 that the sheet material 3 having a coarse scattering density is effective as a sheet material 3 used in a cold time because of its high heat retention effect.

Experiment 2
Two sheet materials 3 having different scattered density of the through holes 2 are prepared, and each of the two sheet materials 3 is subjected to the method for growing the lawn G according to the present embodiment described above in mid-May when the temperature and the ground temperature are warm. When the sheet material 3 was removed and observed in June, the lawn G in the region grown by covering the growth with the sheet material 3 having a fine scattered density of the through holes 2 (the interval between the through holes 2 is narrow) is about 3 cm. On the other hand, the lawn G in the region grown by covering the sheet material 3 with the coarse scattered density of the through holes 2 (the interval between the through holes 2 is wide) causes growth failure (occurrence of illness). It was.

  Therefore, it can be said from Experiment 2 that the sheet material 3 having a fine scattered density is effective as a sheet material 3 used in a hot season because it has good air permeability, is hard to be stuffy, and retains appropriate moisture.

  As described above, it is effective to use the sheet material 3 in which the through holes 2 have different scattered densities in accordance with temperature conditions such as air temperature and ground temperature at the construction site.

  Since the present embodiment is configured as described above, an environment suitable for the cultivation of the lawn G is always obtained, and a good quality lawn G can be easily and reliably grown according to the natural environment, and is suitable for the cultivation. Since a stable environment can be obtained, it is possible to quickly grow a good quality lawn G, and furthermore, work such as watering can be reduced, so that the cost can be improved.

  In addition, the present embodiment can quickly and inexpensively produce a high-quality lawn by reliably creating a new green, a nassery, and switching from a korai green to a bent green.

  In addition, the present embodiment can reliably prevent the grass material 1 sown in the soil E from being moved by the wind and rain by the sheet material 3 and can grow a uniform lawn without unevenness.

  Further, in the present embodiment, when the transparent sheet material 3 is adopted as the sheet material 3, the light necessary for growing the lawn G can be taken in, and the degree of growth of the lawn G can be confirmed. This can be done reliably in a state where it is coated.

  In the present embodiment, the sheet material 3 is also used when both the sowing method and the sowing method are used in combination.

  Hereinafter, a method for growing the lawn G will be described with reference to FIGS.

First, about 20 m ² of bundled turf seedlings 1a (turf material 1) are loosened with water, and the separated turf seedlings 1a are spread evenly on about 1000 m ² of soil E (shaped and leveled green surface). In addition, the bent turf (bent grass) is employ | adopted as the lawn G to grow (refer FIG. 3).

  Subsequently, as shown in FIG. 9, the soil 7 is applied to such an extent that the grass seedlings 1a are hidden (not blown by the wind), fertilizer is applied to the soil 7, and the grass seed 1b is seeded thereon.

  Subsequently, as shown in FIG. 10, a buggy tire 8 of a bunker leveler is run to form unevenness on the joint 7, or a streak is formed by bunker rake.

  The concave portions 9 such as irregularities and streaks formed in the joint soil 7 serve to promote the germination of the turf seed 1b by exhibiting the function of a so-called nursery bed and enhancing the water retention function of the joint soil 7. Become.

  Subsequently, as illustrated in FIG. 11, a region where the turf seedling 1 a and the turf seed 1 b are spread is covered with a plurality of sheet materials 3.

  Thereafter, the lawn G is grown in the same process as in the first embodiment.

  Since it is configured as described above, the use of the sheet material 3 makes it possible to make the most of the merits of using both the sowing method and the sowing method (which can grow a uniform lawn G). In addition, it is possible to grow a good quality lawn G with certainty.

  The rest is the same as in the previous embodiment.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
