Description

[Technical field]

[0001] The present invention relates to How to plant a root ball The term "root ball" refers to the lump of roots (plant) and soil that appears when a plant is removed from a pot or dug up in a garden. [Background technology]

[0002] Conventionally, the root ball is grown in a pot, then removed from the pot and planted in the ground on which a weed-control sheet has been laid. This conventional root ball has a diameter of about 100 mm and a height of about 150 mm. In order to plant root balls of this size, as shown in Figure 10, T-shaped or cross-shaped cuts 32 are made in weed control sheet 31, the soil at cut 32 is then dug up, and root ball 30 is planted in the excavated area. The excavated soil is then backfilled. The cuts are made in weed control sheet 31 because it is necessary to dig up the soil in order to plant a root ball with a diameter of about 100 mm and a height of about 150 mm, and this digging up work is made possible.

[0003] The method of making cuts in the weed control sheet is also described in Patent Document 1. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 5-91365 Summary of the Invention [Problem to be solved by the invention]

[0005] The above-mentioned conventional planting method of making cuts 32 in weed-control sheet 31 requires many steps, such as first making cuts 32 in weed-control sheet 31, then digging up the soil in the area of ​​cut 32, planting root ball 30 there, and then backfilling the excavated soil. Therefore, the work required for planting is troublesome. Furthermore, unless the cuts 32 are made in the weed-control sheet 31, as described above, the soil cannot be dug up and the root ball 30 cannot be planted. Furthermore, with the traditional method, the remaining soil that is used to fill in the planting hole when it is excavated (the volume of the planted root ball) is generated as residual soil, which is troublesome because it requires time and money to remove.

[0006] Another problem is that after planting, the soil in the slit 32 (which exists around the planted root ball 30) becomes exposed, causing weeds to grow around the planted root ball 30. To avoid this problem, it is necessary to cover the slit 32 with tape 33 after planting the root ball 30, which makes the planting process even more difficult.

[0007] Furthermore, since the method described in Patent Document 1 also involves cutting slits in the weed-control sheet, it is naturally necessary to apply tape to the slits in order to prevent weeds from growing thickly, which similarly makes the work required for planting more difficult.

[0008] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a root ball and a method for planting which facilitate the work required for planting. [Means for solving the problem]

[0009] In order to achieve the above object, the present invention How to plant a root ball The method comprises the steps of: planting a root ball (1) previously planted and grown in a pot (2) having an inverted truncated cone shape with an upper diameter of 25 to 50 mm, a lower diameter of 10 to 20 mm, and a height of 30 to 70 mm, or an inverted truncated square pyramid shape with an upper diagonal of 25 to 50 mm, a lower diagonal of 10 to 20 mm, and a height of 30 to 70 mm, in soil (10) having a weed-proof sheet (11) laid on the surface thereof; The soil (10) is then opened using an opening tool (20) to open the root ball (1). The planting hole (12) From above the weed control sheet (11), breaking through the weed control sheet (11) The soil is then opened to spread it further.The root ball (1) is then removed from the pot (2) and inserted into the planting hole (12) from above for planting. So, The opening device (20) has a main body (21) and a sharp perforating portion (22) at a tip portion lower than the main body (21), and the perforating portion (22) opens the soil (10) by pushing it apart, and the broken-through portion of the weed control sheet (11) is folded vertically downward in succession from the adjacent portion of the weed control sheet (11) to form a weed control hanging portion (11a) that fits along the inner peripheral surface of the planting hole (12). It is characterized by:

[0012] The opening device (20) has a body (21) having a planar shape of the same size as the planar shape of the upper surface of the root ball (1), and forms a planting hole (12) in the soil (10) having a planar shape of the same size as the planar shape of the upper surface of the root ball (1). It is characterized by:

[0013] Furthermore, the root ball planting method of the present invention is characterized in that the opening device (20) is provided with a positioning stopper (23) on the main body (21) that is wider than the main body (21) and has its lower surface abutting the upper surface of the weed control sheet (11) to allow the drilling portion (22) to reach a depth equal to the height of the root ball (1).

[0014] Furthermore, the method for planting a root ball of the present invention is characterized in that the root ball (1) is composed of at least one variety selected from the group consisting of gazania, thyme, rosemary, buckwheat sprout, catmint, baby sunrose, and ivy.

[0015] Here, the symbols in parentheses indicate corresponding elements or items in the drawings and in the detailed description to be described later. Effect of the Invention

[0016] According to the present invention,The root ball taken out of the inverted truncated cone pot or the inverted truncated square pyramid pot is inserted from above into a planting hole formed in the soil by the opening tool, and planted, so the work required for planting is extremely easy. That is, the planting hole is formed by breaking through the weed control sheet from above with the opening tool, and the overall shape of the hole corresponds to the root ball, so the planting work is completed by simply inserting the root ball into the hole. Therefore, unlike the conventional technology, it is not necessary to perform many steps such as making a slit in the weed control sheet, digging up the soil in the slit, planting the root ball there, and backfilling the excavated soil. In addition, in the conventional method, the remaining soil (the volume of the planted root ball) that is backfilled when the planting hole is excavated is generated as surplus soil, but this invention does not have such a problem. Therefore, planting can be performed with extremely simple work and without any particular cost.

[0017] The reason why there is no need to make cuts in the weed control sheet is because the root ball is smaller than that of the conventional technology. In other words, the pot into which the root ball is planted is an inverted truncated cone with an upper diameter of 25 to 50 mm, a lower diameter of 10 to 20 mm, and a height of 30 to 70 mm, or an inverted truncated square pyramid with an upper diagonal of 25 to 50 mm, a lower diagonal of 10 to 20 mm, and a height of 30 to 70 mm. This makes the root ball correspondingly smaller, and there is no need to make cuts in the weed control sheet and dig up the soil, as was the case with the conventional technology.

[0018] Furthermore, the root ball removed from the pot is an inverted truncated cone or pyramid (i.e., narrower at the bottom than at the top) that corresponds to the pot, making it easier to insert into the planting hole.

[0019] Furthermore, since no slits are formed in the weed-control sheet, it is possible to prevent weeds from growing through the slits.

[0020] Furthermore, the work of applying tape to the slits to prevent weeds from growing in the slits can be omitted, making the work required for planting even easier.

[0021] Furthermore, the root ball of the present invention is composed of at least one of the following varieties: gazania, thyme, rosemary, buckwheat, catmint, baby sunrose, and ivy. These varieties are highly reproductive, evergreen, and perennial, so by planting them, it is easy to green a wide area, such as the median strip of a road, the slope of a river, the site or rooftop of a factory, etc.

[0025] Furthermore, according to the root ball planting method of the present invention, the main body of the opening device has a planar shape corresponding to the planar shape of the upper surface of the root ball, so that this main body can easily form a planting hole with an opening corresponding to the size of the root ball.

[0026] Furthermore, the perforated portion below the main body opens by pushing the soil apart, and the broken-through portion of the weed control sheet becomes the hanging weed control section that runs along the inner periphery of the planting hole, so weeds can be prevented from growing more reliably. In other words, not only is the top surface of the soil adjacent to the planting hole covered by the weed control sheet, but the sides (the surfaces that run along the inner periphery of the planting hole) are also covered by the hanging weed control section. This makes it possible to prevent weeds from growing in the soil adjacent to the planting hole.

[0027] Furthermore, according to the root ball planting method of the present invention, a positioning stopper is provided on the opening device, and the bottom surface of the stopper is brought into contact with the top surface of the weed control sheet to allow the drilling section to reach the same depth as the height of the root ball, so the depth of the planting hole can be easily adjusted to match the height of the root ball, making planting work even easier.

[0029] The above-mentioned patent documents do not describe at all a small root ball that is planted in an inverted truncated cone pot with a top diameter of 25-50 mm, a bottom diameter of 10-20 mm, and a height of 30-70 mm, or an inverted truncated square pyramid pot with a top diagonal of 25-50 mm, a bottom diagonal of 10-20 mm, and a height of 30-70 mm. Also, a planting hole that corresponds to the planar shape and height of the root ball is formed in the soil covered with the weed control sheet using an opening tool without forming a slit in the weed control sheet, and then planted. How to plant a root ballis not mentioned at all in the above mentioned patent documents. [Brief description of the drawings]

[0031] A root ball 1 according to an embodiment of the present invention will be described with reference to Fig. 1. As mentioned above, the "root ball" refers to the lump of roots (plant 1a) and soil 1b that appears when a plant is removed from a pot or dug up from a garden.

[0032] The root ball 1 according to this embodiment is planted and grown in a pot 2 in advance, and then removed from the pot 2 and planted in a planting hole 12 formed in soil 10 having a weed control sheet 11 laid on the surface. The plant can be planted in the pot 2 using seeds, roots, or stems.

[0033] The shape of pot 2 in which root ball 1 is planted is an inverted square pyramid with an upper diagonal of 25 to 50 mm, a lower diagonal of 10 to 20 mm, and a height of 30 to 70 mm. Therefore, the size of root ball 1 removed from pot 2 is also an inverted square pyramid with an upper diagonal of 25 to 50 mm, a lower diagonal of 10 to 20 mm, and a height of 30 to 70 mm.

[0034] The pot 2 may also be in the shape of an inverted truncated cone with an upper diameter of 25 to 50 mm, a lower diameter of 10 to 20 mm, and a height of 30 to 70 mm.

[0035] This root ball 1 is planted in a planting hole 12, which is formed using an opening tool 20. That is, the opening tool 20 is used to form in the soil 10 a planar shape of the same size as the planar shape of the top surface of the root ball 1 and a depth corresponding to the height of the root ball 1, by breaking through the weed control sheet 11 from above. The root ball 1 is then inserted from above into the planting hole 12 thus formed and planted. Note that the root ball 1 is a truncated quadrangular pyramid whose bottom is narrower than its top, and therefore can be easily inserted into the planting hole 12.

[0036] The root ball 1 according to this embodiment having such a configuration can be planted simply by inserting it into the planting hole 12 from above, making the work required for planting extremely easy. Also, because no cuts are made in the weed-control sheet 11, it is possible to prevent weeds from growing through the cuts. Furthermore, there is no need to apply tape to cover the cuts, making the work required for planting even easier.

[0037] The reason why there is no need to make cuts in the weed control sheet is because the root ball in this embodiment is small. That is, the pot into which the root ball is planted is a small inverted truncated pyramid with an upper diagonal of 25 to 50 mm, a lower diagonal of 10 to 20 mm, and a height of 30 to 70 mm. Therefore, the root ball is correspondingly small (conventional root balls have a diameter (or diagonal) of about 100 mm and a height of about 150 mm). As a result, there is no need to make cuts in the weed control sheet and dig up the soil for planting, as in the conventional technology.

[0038] The root ball 1 according to this embodiment is composed of at least one of the following varieties: gazania, thyme, rosemary, buckwheat, catmint, baby sunrose, and ivy. These varieties are highly reproductive, evergreen, and perennial, so they can be used to green a wide area (for example, road medians, river slopes, factory sites, building rooftops, etc.) with very little work.

[0039] Next, a method for planting a root ball according to this embodiment will be described with reference to Figures 2 to 6. In this method for planting a root ball, a root ball 1 is used that has been planted and grown in a pot 2 in the shape of an inverted truncated square pyramid, with an upper diagonal of 25 to 50 mm, a lower diagonal of 10 to 20 mm, and a height of 30 to 70 mm.

[0040] First, as shown in Figures 2 to 4, a planting hole 12 is formed in soil 10 covered with a weed control sheet 11 using an opening tool 20. Specifically, the opening tool 20 is thrust into the weed control sheet 11 laid on the top surface of the soil 10 from above, breaking through the weed control sheet 11, and the opening tool 20 opens the soil 10 by pushing it apart, forming the planting hole 12. This makes it possible to easily form a planting hole 12 that corresponds to the shape of the opening tool 20 simply by inserting the opening tool 20 into the planting hole 12 .

[0041] The opening device 20 has a main body 21 that has a planar shape of the same size as the planar shape of the top surface of the root ball 1, and has a sharp hole-drilling part 22 at the tip below the main body 21. This makes it possible to easily form a planting hole 12 that corresponds to the size of the root ball 1 by spreading the soil 10 with the hole-drilling part 22. Therefore, there is no need to dig up the soil 10 manually.

[0042] Furthermore, by piercing the opening device 20, the pierced portion of the weed control sheet 11 can be folded vertically downward in continuation from the adjacent portion of the weed control sheet 11. Then, as shown in Figures 3 and 4, this folded portion of the weed control sheet 11 can form a hanging weed control part 11a that fits along the inner periphery of the planting hole 12. The hanging weed control part 11a thus formed is present between the root ball 1 inserted in the planting hole 12 and the soil 10 surrounding it. This makes it possible to more reliably prevent weeds from growing in the surrounding soil 10.

[0043] Next, as shown in Figures 5 to 7, the root ball 1 planted in the bot is taken out by grasping its upper end and pulling it out of the pot 2, and in this state, it is inserted from above into the planting hole 12 and planted. Since the shape of the root ball 1 corresponds to the shape of the planting hole 12 formed by the opening device 20, the root ball 1 can be easily inserted into the planting hole 12 and no unnecessary gap is formed between the two. If an unnecessary gap were to be formed, work would be required to fill it in, but in this embodiment, such work is not necessary, making the work required for planting even easier.

[0044] 2 to 4, the opening device 20 used here is equipped with a positioning stopper 23. The stopper 23 is formed on the main body 21 of the opening device 20 so as to be wider than the main body 21, and its underside abuts against the upper surface of the weed control sheet 11, thereby causing the drilling section 22 to reach a depth equal to the height of the root ball 1. Therefore, by inserting the opening device 20 into the soil 10 until the underside of the stopper 23 abuts against the weed control sheet 11, it is possible to easily form a planting hole 12 with a depth corresponding to the height of the root ball 1. This also makes it easy to carry out the work required for planting.

[0045] Specific examples of the opening tool 20 used in the root ball planting method according to this embodiment are shown in Figs. 8 and 9. Both of these opening tools 20 include a handle 24 for manual operation in addition to a main body 21, a drilling part 22, and a stopper 23. The planting hole 12 can be formed by applying a downward force to this handle 24. The opening tool 20 shown in Fig. 9 has a footrest 25 formed in the middle of the main body 21. The planting hole 12 can be formed even more easily by applying a foot force to this footrest 25. This is effective when the soil 10 is hard.

[0046] The root ball 1 used in the planting method according to this embodiment is not particularly limited, but suitable examples include gazania, thyme, rosemary, buckwheat, catmint, baby sunrose, and ivy. These have strong reproductive power, are evergreen, and are perennial, so they are effective when used in places where greening is desired throughout the year.

[0047] The root ball and the planting method according to this embodiment are suitable for use in large areas such as road medians, river slopes, factory sites, building rooftops, etc., as well as in relatively small areas such as ordinary homes. In addition, plants other than gazania, thyme, rosemary, buckwheat, catmint, baby sunrose, and ivy can also be used as root balls. [Explanation of symbols]
