Description

  The present invention relates to a seedling raising method for growing turf, a pot turf seedling and a turf seedling transplanting method.

  The lawn construction method includes the Zhang turf construction method in which the sod that is obtained by punching the grown lawn into a flat plate is spread on the construction site, the sowing method in which the seeds of turf are cultivated directly on the construction site, and the seedling seedlings are transplanted to the creation site. There are construction methods to do.

  The Zhang Shiba method can shorten the working time but is disadvantageous in terms of cost. In addition, since the grass roots are cut, the grass is difficult to settle on the site, and it may be difficult to maintain the grass.

  In the sowing method, the turf tends to settle on the site, but the seeds may be washed away by rain. In addition, when golf courses are repaired in the spring, seeds are sown in winter, so turf germination and growth may be delayed.

  On the other hand, in this turf seedling transplanting method, seedlings that have been grown using a cell tray (nursery seedling tray) (see, for example, Patent Documents 1 and 2) have a predetermined leaf length. After that, it is transplanted to the site.

  However, when turf seedlings are grown using this known seedling raising method (Patent Documents 1 and 2), the roots are not sufficiently stretched until transplanting, and the period until the strain grows greatly may increase. In addition, when a turf seedling of insufficient size is transplanted to the establishment site, the transplanted turf seedling is difficult to settle and it becomes difficult to form the entire lawn cleanly.

  An object of the present invention is to provide a turf seedling raising method and a turf seedling capable of increasing the turf seedling strain.

  Another object of the present invention is to provide a method for transplanting turf seedlings that can be easily transplanted and cultivated on the established land.

  The lawn seedling raising method according to the first aspect of the present invention includes a sowing and germination step for seeding and germinating turf seeds in floor soil accommodated in a seedling pot of a container, and lawn that has been germinated and grown in the seedling pot. A cutting step of cutting seedling leaves at a predetermined cutting height, wherein the cutting step is repeatedly performed a plurality of times over a seedling period from germination to transplanting in the seedling pot. .

  In this turf seedling raising method, in the cutting step in the first period of the seedling period, the leaves of the turf seedling are cut at a first cutting height (H1), and the cutting step in the second period after the first period. Then, the leaves of the turf seedling are cut at a second cutting height (H2) (H1> H2) lower than the first cutting height (H1), and in the cutting step at the final stage of the seedling raising period, It is desirable to cut the grass seedling leaves at a third cutting height (H3) (H2> H3) lower than the second cutting height (H2).

  Further, the pot lawn seedling according to the second aspect of the present invention has a predetermined cutting height for leaves of lawn seedlings that have sprouted and grown from lawn seeds sown in the floor soil accommodated in the seedling pot of the container. It is characterized by being nurtured by cutting and repeatedly performing this cutting several times.

  Furthermore, in the method of transplanting turf seedlings according to the third aspect of the present invention, the leaves of turf seedlings that have sprouted and grown from turf seeds sown in the floor soil accommodated in the seedling pots of the container have a predetermined cutting height. Mowing in the cutting process, a small drilling process in which a plurality of small holes are drilled in a specific area of the creation site to loosen the created turf surface, a transplanting drilling process in which a transplanting hole is drilled in the specific area, and the cutting process is performed. A transplanting step of transplanting a pot lawn seedling into the transplanting hole.

  In this method of transplanting turf seedlings, the cutting process is repeated a plurality of times, and the cutting height of the turf seedlings in the cutting process in the finishing stage before transplanting is the cutting height of the turf seedlings in the cutting process in the growth stage. It is desirable to make it lower than this.

  According to the turf seedling raising method of the present invention, the turf seedling that has been germinated and grown in the seedling pot is trimmed at a predetermined cutting height, and the seedling nurtured from germination to transplanting is carried out. Repeated multiple times over a period of time, so that the roots can be sufficiently stretched on the floor soil in the nursery pot, the lawn seedlings can be made larger, and a lawn seedling suitable for transplanting to the established land Can be trained.

  Further, according to the pot turf seedling of the present invention, the leaves of the turf seedlings that have sprouted and grown from the turf seeds sown in the floor soil accommodated in the seedling pot of the container are cut at a predetermined cutting height. Since the seedlings are nurtured by repeatedly performing the above, a pot turf seedling having a large strain and sufficient roots can be provided.

  Furthermore, according to the method for transplanting turf seedlings of the present invention, a plurality of small holes are made in a specific area of the established land to loosen the created turf surface, and the transplanted holes provided in the specific area are cut at a predetermined cutting height. Since turf seedlings (pot turf seedlings) are transplanted, they can be transplanted and settled relatively easily.

Explanatory drawing for demonstrating the transplanting method of the turf seedling according to this invention. The timing chart which shows the flow of cultivation of the turf seedling in an Example.

  Hereinafter, with reference to the accompanying drawings, embodiments of a lawn raising method, a pot lawn seedling and a lawn seedling transplanting method according to the present invention will be described.

(First embodiment)
First, the lawn raising method according to the first embodiment of the present invention will be described. In the first embodiment, the turf seedlings that have been raised are applied to transplant to a green or fairway of a golf course.

  In this seedling raising method, floor soil is stored in a seedling pot provided in a container, turf seeds are sown on the floor soil in the seedling pot, and turf leaves sprouted from the turf seeds are cut at a predetermined cutting height, Each time a leaf grows, it is cut at a predetermined cutting height. As a container to be used, for example, a seedling tray provided with a seedling pot can be used, and it is desirable that the seedling tray can withstand long-time flooding conditions. For this reason, it is preferable that the material for the seedling tray is a polypropylene resin, a polyethylene resin, or the like. The outer shape of the seedling tray may be an appropriate shape such as a square tube shape or a cylindrical shape, and the top opening side of the seedling pot is somewhat larger than the bottom bottom wall side so that transplanting of the grass seedlings grown in the seedling pot is easy. Those formed large are preferred.

  From the viewpoint of work efficiency and the like, it is preferable to use, as this container, a seedling tray provided with a plurality of the seedling pots arranged in the vertical direction and the horizontal direction, and a commercially available seedling tray formed integrally with these seedling pots. In this case, pot lawn seedlings can be grown in each pot of the seedling tray.

  FIG. 1 shows an 18-hole (so-called number of seedling pots: 18) as an example of a seedling tray. The illustrated seedling tray 10 includes a tray body 11 having a rectangular outer shape (which constitutes a container body). Three seedling pots 12 are provided in the lateral direction of the tray body 11, and the seedling pots 12 are disposed in the vertical direction. There are six, and a total of 18 seedling pots are provided on the tray body 11.

  As the seedling tray 10, other forms may be used. For example, an appropriate one having 16 holes to 512 holes (number of seedling pots: 16 to 512) can be used. The external dimensions (vertical x horizontal x height) of the tray 10 for use are, for example, 50 to 60 cm (L) x 27 to 28 cm (W) x 3 to 8 cm (H), and the height (H) of the seedling tray 10 Becomes the depth of the seedling pot 12.

  FIG. 2 is a cross-sectional view showing a state in which lawn sprouted from lawn seeds sown on the floor soil 1 housed in the seedling pot 12 of the seedling tray 10 is grown. Each seedling pot 12 of the seedling tray 10 has substantially the same configuration, and has a rectangular bottom wall 6, a side wall 7 extending upward from four edges of the bottom wall 6, and upper ends of the four side walls 7. The seedling pot 12 provided with the provided opening 3 and the upper edge 5 extending in the horizontal direction from the opening 3, and adjacent in the vertical and horizontal directions, is connected via the upper edge 5. The bottom wall 6 of each seedling pot 12 is smaller in size than the opening 3, and as shown in FIG. 2, the four side walls 7 extend so as to expand toward the opening 3, By comprising in this way, taking out the pot lawn seedling 2 at the time of transplantation mentioned later becomes easy.

  The dimension of the opening 3 of the seedling pot 12 is set to the following size, for example. When turf seedlings 2 to be transplanted to a golf course green or the like are nurtured, for example, a size of 1.5 to 2.0 cm (vertical) × 1.5 to 2.0 cm (horizontal) is selected. When nurturing the turf seedling 2 to be transplanted on the fairway or the like on the ground, for example, a size of 2.0 to 3.0 cm (vertical) × 2.0 to 3.0 (horizontal) cm is selected. A drain hole 4 is provided in the bottom wall 6 of each seedling pot 13, and ventilation and drainage are performed through the drain hole 4. The vent hole 4 is formed in an appropriate size and shape so that the floor soil 1 accommodated in the seedling pot 12 does not fall. This drain hole 4 may be provided in the lower part of the side wall 7 of the seedling pot 12 in addition to the bottom wall 6 or instead of the bottom wall 6.

  The color of the seedling tray 10 is preferably black from the standpoint that the growth of grass roots in the seedling pot 12 is not inhibited and the generation of algae is suppressed, but in order to prevent the temperature of the seedling tray 10 from becoming high in summer. It may be white.

  As shown in FIG. 3, the seedling tray 10 may be stored in a rice seedling box 20 for growing rice seedlings. In this stored state, as shown in FIG. 3, the bottom of the seedling tray 10 (the bottom wall 6 of each seedling pot 12) is placed on the bottom wall 21 of the rice seedling box 20, and its outer peripheral edge 5a (this outer peripheral edge). The portion is composed of the upper edge portion 5 of the seedling pot 12) is placed on the upper end surface of the side wall 22 of the rice seedling box 20, and the seedling tray 10 is supported by the rice seedling box 20 in such a state. Note that a dedicated storage box may be used instead of the rice seedling box 20. In this case, the depth of the seedling pot 12 can be set to an arbitrary depth, and a storage box corresponding to this depth is selected. Will do.

  By accommodating in the rice seedling box 20 in this way, the seedling tray 10 can be carried with the rice seedling box 20, and work efficiency such as transportation of the seedling tray 10 can be enhanced. In particular, the use of the wooden rice seedling box 20 ensures the air permeability of the seedling pot 12 through the vent hole 4, and can maintain the temperature and humidity in the pot appropriately. The rice seedling box 20 that is no longer needed can be used effectively, and the seedling seedling 2 can be trimmed using a lawn mower (not shown), which will be described later, by accommodating the seedling tray 10 in the rice seedling box 20. Can be done.

  As the floor soil 1 accommodated in each seedling pot 12 of the seedling tray 10, various soils such as field soil and culture soil containing organic matter, and true sand soil can be appropriately used. The composition of the floor soil 1 is preferably the same as or close to the composition of the site where the pot lawn seedling 2 is transplanted. For example, since most of the surface of the fairway of a golf course is made of soil, the pot lawn seedling 2 transplanted to the fairway preferably includes soil (for example, field soil) as the floor soil 1. Further, since most of the surface of the golf course green is made of sand, the pot lawn seedling 2 transplanted to the green preferably contains sand as the floor soil 1. However, the surface of the green is in a state (so-called field soil state) in which soil and sand are mixed with organic residue such as grass that has been cut off while being used.

  For this reason, the common floor soil 1 for the fairway pot lawn seedling 2 and the green pot lawn seedling 2 is preferably one containing soil (preferably field soil) and sand. Is preferably (70-30) :( 30-70), more preferably (60-40) :( 40-60), particularly preferably (55-45): (45-55).

  The floor soil 1 is preferably filled into each seedling pot 12 after the soil and sand are uniformly mixed. For example, if sand is used on the surface of the floor soil 1 and its lower layer is soil, water and fertilizer supplied to the seedling pot 12 will flow to the lower layer. The air permeability and water retention are maintained, and the growth of the turf seedling 2 is promoted.

  The amount of the floor soil 1 accommodated in each seedling pot 12 of the seedling tray 10 is appropriately adjusted according to the capacity of the seedling pot 12, and the volume is, for example, about 50 to 90% of the capacity of the seedling pot 12 However, when the lawn seedling 2 is cut using a lawn mower (not shown) as described later, the depth (D) from the surface of the floor soil 1 to the upper edge of the seedling pot 12 is 5 to 7 mm. Is preferred.

  The floor soil 1 in the seedling pot 12 is sown with appropriately selected types of turf seeds and grown as required to be transplanted. In general, bent turf is stretched on the green of a golf course, and bent turf is used when transplanting to such a green. In addition, gauze turf is stretched on the fairway, and ginseng turf is used when transplanting to such a fairway. The accumulated temperature for germination is about 100 ° C. for bent turf and about 600 ° C. for ginseng turf. As germination conditions, water and light can be given in addition to this accumulated temperature. Can be mentioned.

  The golf course lawn is maintained in the spring before the golf course reaches its busy season and in the fall to maintain bent turf that is western turf for cold regions (to maintain areas that have been peeled off due to summer heat and use) And mainly done. For this reason, the seedling raising of the pot lawn seedling 2 is often performed in winter and summer before maintenance. When growing in winter in preparation for spring maintenance, a nursery device (not shown) equipped with a heater is used to meet the germination temperature (about 100 ° C for bent grass and about 600 ° C for ginseng grass). It is possible to grow the pot turf seedling 2 in a relatively short period of time by germinating and transferring the seedling tray 10 into the greenhouse after germination. In particular, the seedling tray 10 can be easily applied to a seedling container to select an appropriate size as described above, and can be easily moved into a greenhouse. Training can be easily performed. Even in summer, a seedling device, a greenhouse, etc. may be used to accelerate germination.

  The number of turf seeds to be sown in each seedling pot 12 may be about 1 to 10, and the seeding time of turf seeds is an appropriate time in consideration of the seedling period and transplanting period of the pot lawn seedling 2. Just sow.

  The turf germinated from the turf seed (turf after sowing and germination process) is cut at a predetermined cutting height (cutting process) and cut several times until transplanting. Strains grow big. The turf seeds sown in the seedling pot 12 germinate when the above-mentioned germination conditions are satisfied, and after about 10 days have passed since the germination, the turf leaves are harvested at a predetermined cutting height. By cutting, the stock of the pot lawn seedling 2 becomes large, and the stock grows larger by repeating the cutting. The frequency of cutting the turf seedling 2 is appropriately determined according to the growth of the turf leaves, and is preferably about twice a week, but may be once or three times a week.

  When the pot turf seedling 2 is repeatedly cut several times, it is desirable to set the cutting height as follows. That is, in order to promote the growth of the pot lawn seedling 2 during the seedling period from germination to transplanting, it is desirable to gradually reduce the cutting height toward the transplanting time. For example, in the first period of seedling period (between 4 and 6 weeks after germination), the cutting height of the pot lawn seedling 2 is the first cutting height H1, for example, about 10 to 12 mm (for example, about 10 mm). For example, when the depth (D) from the surface of the floor soil 1 in the seedling pot 2 to the upper end of the seedling pot 2 is about 5 mm, adjustment of a lawn mower (not shown) The cutting height is set to about 5 to 7 mm (for example, about 5 mm). Further, in the second period of the seedling raising period (between the period after the first period and the transplanting), the cutting height of the pot lawn seedling 2 is lower than the first cutting height H1 and the second cutting height H2 (H1>). H2), for example, preferably about 7 to 9 mm (for example, about 8 mm). For example, when the depth (D) is about 5 mm, the adjusted mowing height of the lawn mower is about 2 to 4 mm. (For example, about 3 mm). Further, in the final stage of the seedling raising period (that is, the stage before transplantation), the third cutting height H3 (H2> H3), in which the cutting height of the pot lawn seedling 2 is lower than the second cutting height H2. For example, it is preferable to be about 5 to 6 mm (for example, about 6 mm). For example, when the depth (D) is about 5 mm, the adjusted mowing height of the lawn mower is, for example, about 0 to 1 mm ( For example, it is set to about 1 mm. In this way, by setting the first cutting height H1 in the first period of the seedling raising period, a lot of leaves of the pot lawn seedling 2 remain, and thereby photosynthesis is actively performed, and the growth of the lawn seedling 2 is promoted. The roots are stretched greatly, and the strain of Shiba Seed 2 grows larger. In addition, by setting the third cutting height H3 at the final stage of the seedling raising period, the height becomes slightly higher than the height of the turf at the transplant destination, and the adjustment of the turf height after the transplant becomes easy.

  Generally, the length of the green grass on the golf course is about 4 to 5 mm. Therefore, when transplanting the pot lawn seedling 2 to the green, before transplanting (that is, the final stage of the seedling raising period). The leaves of the lawn seedling 2 may be cut at a third cutting height (H3), for example, about 5 to 6 mm, and the transplanted pot lawn seedling 2 leaves are further cut on the green to a length of 4 to 5 mm. (I.e., trimmed to the final cut height and adjusted to the final green turf height).

  In general, the length of the turf on the fairway is about 14 to 16 mm. For this reason, when transplanting the pot turf seedling 2 to the fairway, the leaves of the pot turf seedling 2 may be cut at a third cutting height (H3), for example, about 15 to 17 mm before transplanting. The leaves are further cut on the fairway and adjusted to a length of about 14 to 16 mm (ie, adjusted to be cut at the final cut height and adjusted to the final fairway lawn height). In addition, when transplanting to a fairway in this way, the 1st cutting height H1 of the pot lawn seedling 2 is set to about 22-25 mm, and the 2nd cutting height H2 is set to about 18-20 mm.

  The leaves of the pot lawn seedling 2 may be manually cut using a scissors, a sickle or the like, but can be cut efficiently by using a lawn mower. The lawn mower can mow the lawn at a desired cutting height if the cutting height is set. Even when the seedling tray 10 is used, the seedling tray 10 is stored in a storage box (for example, a rice seedling box). By storing in 20), the lawn mower can be moved on the seedling tray 10 stored in the storage box to easily mow the leaves of the pot lawn seedling 2, and the efficiency of the lawn mowing work can be improved. it can.

  The pot turf seedling 2 thus grown is cut at a predetermined cutting height before transplantation (final stage of the seedling raising period) according to the length of the turf leaf at the transplant destination. Considering transportation of the seedling tray 10 after cutting, the depth (D) from the upper edge 5 of each seedling pot 12 to the surface of the floor soil 1 shown in FIG. 2 is, for example, lawn to the green (or fairway) It is preferably equal to or somewhat longer than the length of turf leaves at the time of transplantation. By making such a length, when the seedling tray 10 is transported, the tip of the leaves of the pot lawn seedling 2 hardly exceeds the upper edge 5 of the seedling pot 12, and the seedling tray 10 is stacked vertically. The leaves of the grass seedlings 2 are good.

  The pot turf seedling 2 grown as described above is sown at a predetermined cutting height from the turf leaves that have sprouted and grown from the turf seeds sown in the floor soil 1 housed in each seedling pot 12. As a pot lawn seedling 2 grown in the field, it is transplanted to a green or fairway of a golf course.

  As described above in detail, in the lawn seedling raising method according to the present embodiment, the mowing process for cutting the leaves of the lawn seedling 2 at a predetermined cutting height is repeatedly performed a plurality of times. The stock grows and its roots are well stretched on the floor soil 1. This is thought to be due to the increased growth of the strain and the generation of anabolic products in order to restore the structure of the veins, organelles, etc. damaged by cutting the leaves of the lawn seedling 2. . Also, until the pot turf seedling 2 is transplanted, it is possible to maintain the growing seedling while increasing the strain by repeating the cutting process a plurality of times, and the growing period can be adjusted according to the timing of transplanting.

  In addition, when the cutting process is repeated in the above-described embodiment, the cutting height of the grass seedling 2 is gradually lowered toward the transplanting time, and in this way, in the first period of the seedling raising period Turf leaves grow large, photosynthesis becomes active, and can promote its growth. As a result, the stock of the pot lawn seedling 2 becomes large and can be rooted widely.

  Moreover, in the above-mentioned embodiment, since the seedling tray 10 is accommodated in the accommodation box (for example, the rice seedling box 20), the work efficiency for the seedling tray 10, for example, the work efficiency such as lawn mowing work can be improved. Further, when raising a pot lawn seedling 2 for a golf course, the rice seedling box 20 can be used effectively as a storage box by using the rice seedling box 20 that is not used in the winter and summer seasons as a seedling raising season. The cost for raising the seedling 2 can be reduced.

  Moreover, in the above-mentioned embodiment, since the ground soil and sand mixed in the seedling pot 12 are used, the soil on the green surface of the golf course that has been created and has passed for a certain period of time is used. Thus, the environment of the soil before and after transplanting the pot turf seedlings 12 becomes close, and as a result, the pot turf seedlings 2 are likely to settle in green.

  Moreover, in the above-mentioned embodiment, although the creation place where the pot lawn seedling 2 is transplanted is the green or fairway of the golf course, it is not limited to this. For example, the development site may be another place where a lawn other than the green and fairway of a golf course is necessary, a park, a soccer field, a baseball field, etc. (a place where a lawn is planted, a place where a lawn will be planted). . Further, in the above-described embodiment, the description has been given taking bent turf and ginseng turf as an example of turf, but the types of turf are wild turf, Hime Koroshiba, Tifton 419, Tifton 328, Tifd Wharf, St. Augustine glass, bluegrass. , Fescue, ryegrass and the like.

  Moreover, in the above-mentioned embodiment, although the seedling raising period is about 2 months, it may be longer or shorter. In addition, the cutting height of the pot lawn seedling 12 is the first cutting height (H1) in the first period of the seedling raising period, the second cutting height (H2) in the second period, and the third cutting height in the final stage. Although the height (H3) is set, the cutting height in the first period (or the second period) can be set to be low over two or more stages.

  In the above-described embodiment, the seedling tray 10 provided with a large number of seedling pots 12 is used for raising a plurality of pot lawn seedlings 2. However, a plurality of single seedling pots 12 are used for raising seedlings. May be. In this case, by arranging a plurality of seedling pots 12 in a storage box (for example, a rice seedling box 20 or the like), the management and transportation of the pot lawn seedling 2 can be facilitated.

  In the above-described embodiment, the mowing process is mainly described as the seedling raising method. However, in this seedling raising method, other processes necessary for raising the seedling, water supply to the pot lawn seedling 2 (water supply process) ), Fertilizer administration to the pot turf seedling 2 (fertilizer administration process), sterilization to the pot turf seedling 2, spraying of the insecticide (sterilization, insecticide spraying process) and the like. In particular, the supply of water to the pot turf seedling 2 is important in order to make the roots stretch more and make the turf seedling 2 stock larger. Water supply, fertilizer administration, sterilization, insecticide spraying, and the like are appropriately performed for growing the pot lawn seedling 2.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. The second embodiment is a method of transplanting the pot lawn seedling 2 in the first embodiment to a creation site (for example, a green of a golf course).

  The method for transplanting the pot turf seedling 2 according to the present embodiment includes a small hole drilling process in which a plurality of small holes are drilled in the planted ground to loosen the planted turf surface, a transplant drilling process in which a transplant hole is drilled in a specific area, and a pot grass A transplanting step of transplanting the seedling 2 into the transplanting hole.

  First, the small hole drilling process will be described. The creation site is a place where the pot lawn seedling 2 grown in the seedling pot 12 is transplanted, and this creation site is a place where a lawn is planted such as a golf course green, a park, a soccer field, and a baseball field. In the following, description will be made by applying to golf course green.

  For example, in order to transplant to the golf course green 100, a plurality of small holes 40 are formed in relation to a specific region 102 to be transplanted (for example, a region where the lawn is peeled off) (small hole forming step). For example, as shown in FIG. 4, the plurality of small holes 40 are preferably formed in a plurality (for example, about 10 to 30) around the specific region 102 and its periphery, and the size thereof is about 5 to 10 mm in diameter, preferably 6 in diameter. About 8 mm (for example, about 8 mm). By making a plurality of small holes 40 in this manner, the area to be transplanted on the green surface is loosened, air enters the green surface, drainage is improved, and the survival of the turf seedling 2 after transplanting is improved.

  In the next transplanting hole forming step, the transplanting hole 30 is formed in the specific region 102. The size of the transplant hole 30 corresponds to the size of the floor soil 1 attached to the pot lawn seedling 2 (in other words, the size of the seedling pot 12), and has a diameter of about 10 to 25 mm, preferably 15 to 18 mm ( For example, about 16 mm).

  In addition, the small hole 40 and the transplant hole 30 can be performed using a drilling tool, a transplant tool, a scoop, etc., for example. The sizes, depths, and intervals of the small holes 30 and the transplant holes 40 are appropriately determined according to the area of the specific region 102, the size of the pot lawn seedling 2, and the like. It is determined appropriately according to “the area of 102” and the like.

  Thereafter, transplantation of the pot lawn seedling 2 is performed (transplantation process). The pot lawn seedling 2 to be transplanted is grown as in the first embodiment (seeding / germination process and a plurality of cutting processes), and the pot lawn seedling 12 thus grown is transplanted into the transplanting hole 30. The The transplanting of the pot lawn seedling 2 into the transplanting hole 30 may be performed manually, but if there are many transplanting holes 30, a transplanting machine for transplanting the pot lawn seedling 2 may be used. In addition, after transplanting the pot lawn seedling 2, sand (and / or soil) may be sown on the transplanted part of the pot lawn seedling 2, and then the lawn surface on the green 100 may be aligned using a roller or the like. After that, water is further sprayed, the turf seedling 2 transplanted with a lawn mower or the like and the surrounding turf leaves are trimmed at the finished cutting height, and the specific region 102 and the surrounding turf surface around which the turf seedling 2 has been transplanted are removed. You may make it align.

  As described above in detail, in the transplanting method of the pot seedling 2 according to the present embodiment, since the surface of the green 100 is loosened by the small hole 40, air and the root of the pot lawn seedling 2 transplanted in the transplanting hole 30 Water becomes easy to reach, so that the pot lawn seedling 2 can be quickly settled, and the time required to form the lawn can be shortened.

  Moreover, in the transplanting method of the pot seedling 2 according to the present embodiment, since the pot lawn seedling 2 takes root earlier and the lawn spreads, by transplanting the pot lawn seedling 2 as appropriate to the construction site where the maintenance of the lawn is planned, The turf can be renewed or the turf type can be changed in 2 to 3 years without completely replacing the turf as in the conventional Zhang turf method.

  The following examples further illustrate the present invention, but the present invention is not limited to the examples.

  I grew seedlings for green grass in golf courses. The type of turf was bent turf. Using a seedling tray equipped with a seedling pot with a rectangular hole with a size of 1.6 cm (vertical) x 1.6 cm (horizontal) at the upper end, this seedling tray is housed in a rice seedling box (container box) did. The floor soil was accommodated in each seedling pot so that the depth from the upper edge of the seedling pot to the floor soil surface was 5 mm.

  About 5 to 6 seeds of bent turf were sown in each seedling pot and given sufficient water. This seedling tray was placed in a greenhouse and maintained at about 30 ° C. while giving sufficient water.

  The process from seeding to immediately before transplantation was as shown in FIG. Assuming that the time of sowing was day 0, seeds germinated on the third day (seeding / germination step). Then, on the 10th day after sowing, the first lawn seedling was cut (cutting step). At this time, the grass seedlings were cut with a lawn mower, and the cutting height was 10 mm (the cutting height of the lawn mower was set to 5 mm). Thereafter, in the cutting process up to the 49th day (2 weeks before transplantation), cutting was carried out at a cutting height of 10 mm twice a week. In the cutting process after the 49th day, cutting was performed at a cutting height of 8 mm twice a week (the cutting height of the lawn mower was set to 3 mm). Subsequently, in the last cutting process, cutting was performed on the 61st day at a cutting height of 6 mm (the borrowed height of the lawn mower was set to 1 mm).

  By doing so, compared with turf seedlings that were grown without cutting, (1) the roots in the floor soil were spread more widely, and (2) a pot turf seedling with a large strain could be obtained.
