Description

  The present invention provides a planting method for planting trees, a method for planting artificial ground such as a roof, a veranda or a sidewalk by applying the planting method, and afforesting an artificial ground by applying the planting method. About the system.

In cities, greening on artificial grounds provided on buildings, such as rooftops or verandas, is being promoted for the purpose of reducing the heat island phenomenon or visual improvement effects, etc. Since the total load that can be applied on the roof for greening, such as soil and materials, is set at 60 kg or less per 1 m ² according to relevant laws and regulations when greening trees, the development of greening systems that can satisfy such limitations It is required. Therefore, the following greening system is proposed by patent document 1 mentioned later.

  FIG. 9 is a longitudinal sectional view showing the configuration of the tree planting system disclosed in Patent Document 1. In the figure, reference numeral 51 denotes a roof-top slab constructed of an artificial ground such as concrete. A waterproof layer 52 is disposed on the roof roof slab 51, and a growth base 53 is formed on the waterproof layer 52 to a thickness of 15 cm or less. The growth base 53 comprises a waterproof sheet 54 disposed on the waterproof layer 52, and a water-retaining sheet 55 composed of a woven and knitted fabric on the waterproof sheet 54, and a drainage layer having a three-dimensional mesh structure in a helical shape. 56, a water-permeable sheet 57 composed of a woven fabric or the like, and a soil 58 for planting are laminated in this order. The soil 58 is formed by mixing volcanic ash weathered subsoil, charcoal and zeolite at an appropriate composition ratio, and has a thickness of about 5 cm. Further, a water supply pipe 61 is buried in the soil 58, and water in the water supply pipe 61 is supplied from the water supply pipe 61 to the water conductive sheet 57.

  On the other hand, the three-dimensional structure net 60 is also embedded in the soil 58 described above, and the three-dimensional structure net 60 prevents erosion by rain water on the surface of the soil 58 and wind erosion by wind and is planted in the soil 58 The roots of plants and trees are entangled in the three-dimensional structure net 60.

JP, 2007-289207, A

  However, in such a conventional greening system, since the thickness of the soil 58 is as thin as about 5 cm, plant roots can not be planted at a deep position in the soil 58. Therefore, there is a problem that the trees are easily overturned by wind and rain when planting trees growing to a height of several tens of cm or more on such soil 58, apart from grasses having short heights. By the way, in the conventional tree planting system, as described above, the three-dimensional structure net 60 is embedded in the soil 58, but in trees less than one year after planting in the soil 58, the root of the tree Is not sufficiently entangled in the three-dimensional structure net 60, and therefore, overturning of a tree planted in the soil 58 due to wind and rain can not be prevented by the three-dimensional structure net 60 during this period.

  The present invention has been made in view of such circumstances, and a planting method capable of preventing overturning due to wind and rain even if it is a tree about one year after planting, and this planting method are applied. And a method for greening an artificial ground such as a roof, a veranda or a sidewalk, and a greening system for greening an artificial ground by applying the greening method.

It is a fragmentary longitudinal cross-sectional view of this afforestation system after cultivating the fixed planted plant for a suitable period of time. It is a disassembled perspective view which shows an example of the raising seedling box shown in FIG. It is a longitudinal cross-sectional view which shows the structure of the greening system disclosed by patent document 1. FIG.

  A planting method according to the present invention, a greening method to which the planting method is applied, and a greening system to which the greening method is applied will be described in detail based on the drawings. Note that the planting method, the planting method, and the planting system described in the present embodiment are an example for explaining the purpose of the present invention, and it is understood that the present invention includes modifications and alterations without departing from the scope of the present invention. It's too late.

  1 to 6 are explanatory diagrams for explaining an example of the planting method, the planting method, and the planting system according to the present invention in accordance with the cultivation procedure of the target plant. Here, the target plants are mainly trees, but in the case of trees, either shrubs or trees can be used. For example, scutellaria spp., Evergreen pokeweed, scallops, scallops, scallops, scallops, blueberries, white oak, It is possible to use Kantsubaki, Filipuri bed, Filifera aurea etc.

  As shown in FIG. 1, seedlings Ba, Ba,... Of planted plants obtained by cuttings or germination etc. are planted in the alley (a), and the alley is grown for several months to several years, 30 cm Seedlings Bb, Bb,... For transplanting the determined plants grown up to around 150 cm are obtained (b). Thus, when the transplanting seedlings Bb, Bb, ... are obtained, the transplanting seedlings Bb are dug up from the alley, and after removing the soil of the alleys from the roots of the transplanting seedlings Bb, the removable bottom plate (not shown) And (c) transplanted into the soil for soiling S2 at the time of raising seedlings (to be described later) filled in the raising seedling box 10 having c).

  FIG. 8 is an exploded perspective view showing an example of the nursery box 10 shown in FIG. The nursery box 10 has a box shape having a rectangular plan view, and the bottom plate 12 is detachably supported by a support portion 11 a which is spanned in a grid shape at the bottom opening of the surrounding wall (frame member) 11. The bottom plate 12 has, for example, a plurality of square pores 14, 14... Opened, and roots of the transplanting seedlings transplanted to the nursery box 10 pass through the pores 14, 14. It can be extended outwards of ten. Further, a plurality of water draining holes 11b, 11b, ... are opened at appropriate intervals in the circumferential direction at a position near the bottom of the surrounding wall 11 so that drainage in the nursery box 10 can be maintained well. ing. The bottom plate 12 may be more easily removed by making the one side wall portion of the surrounding wall 11 openable and closable.

  As shown in FIG. 1 (c), in the nursery box 10, soil for planting S2 is filled so as to have a depth of 100 mm or less, preferably about 50 mm to about 60 mm. Therefore, it is preferable to cut out the root of the transplanting seedling Bb to a depth degree of the planting soil S2 in the nursery box 10 as needed, for the transplanting seedling Bb excavated from the alley. In addition, the depth of the greening soil S2 in the nursery box 10 may be determined according to the place where the greening system is to be installed as described later. For example, in the case where the greening system is installed on the rooftop, The soil S2 may have a depth of 100 mm or less, preferably about 50 mm to 60 mm. On the other hand, when constructing a revegetation system on a place other than the roof, for example, a sidewalk, the revegetation soil S2 can have a depth of about 50 mm to about 200 mm.

  By the way, the above-mentioned soil S2 for tree planting and soil S1 for tree planting laid on artificial ground as will be described later are mainly mixed in a predetermined ratio of straw and clay, and the specific gravity thereof is less than 1 is there. A porous natural stone or artificial stone having multiple open cells, that is, a multi-connected porous stone can be used as a pebble, such as perlite made of bola earth, or pearlite and rosin, etc. The diameter should be approximately 2 mm or more and 4 mm or less. In addition, soiling soil S1 and soiling soil S2 include soil material such as coconut peat, humus soil and wood chips, and / or fertilizer material such as fermented chicken manure and chemical fertilizer, etc. Can.

  Here, in the case of greening soil using stones such as pumice with many holes formed only on the surface or stones without air bubbles, drainage is bad and root rot occurs in the planted trees There is a risk. On the other hand, in the case of soil for revegetation using multi-communication pore stone, even if it is a mixture of clay, water moves through the communication pore in the adjacent multi-communication pore stone. It is well drained from the revegetation soil, and rooted rot does not occur in the planted trees. On the other hand, since water and fertilizer dissolved in water are held in the communication pores of the multi-communication pore stone, they are excellent in water holding capacity and fertility.

  In addition, when the particle size of the multi-connected pore stone is less than about 2 mm, the density of the moss is relatively high, and therefore the density (mass / volume) of the soil for greening mixed with the moss becomes excessive. It can not be used for cultivation by the nursery box 10 and greening of artificial ground. On the other hand, it has been obtained that the fact that the particle diameter of the multi-communication pore stone exceeds about 4 mm adversely affects the growth of the planted tree. On the other hand, in the case of a revegetation soil using multi-communication pore stone having a particle diameter of about 2 mm or more and about 4 mm or less, it is a density that can be used for cultivation by the nursery box 10 and replanting artificial ground; There is no risk of adversely affecting the growth of planted trees.

  Here, the shape of the pores (through holes) 14, 14,... Opened in the bottom plate 12 of the nursery box 10 shown in FIG. 8 may be an appropriate shape such as a circular shape or a polygonal shape. The inside diameter of 14, 14, ... is made as large as possible so as to prevent the fall of the weir that constitutes the greening soil S2. That is, the inner diameter of the pores 14, 14... Is preferably about 2 mm or more and about 4 mm. By this, the fall which constitutes the soil S2 for tree planting is prevented, and while the composition ratio of the soil S2 for tree planting is held, the root of the seedling Bb for transplantation transplanted to the nursery box 10 has pores 14, 14, ... It becomes easier to pass through the inside.

  As described above, when the operation for transplanting the transplanting seedlings Bb into the greening soil S2 in the nursery box 10 is completed, sufficient sunlight, water and fertilizer are given to grow the transplanting seedlings Bb. As a result, a plurality of roots R, R, ... generated from the transplanted seedling Bb are densely grown in the nursery box 10, and a plurality of pores 14, 14, open in the bottom plate 12 of the nursery box 10. ... extend from both (see both FIG. 8) (FIG. 1 (d)). In addition, the breeding place of the seedling Bb for transplanting selects indoors or the outdoors suitably according to the kind and growing season of the transplanted fixed plant. Moreover, although the cultivation period of the seedling Bb for transplanting in the nursery box 10 changes with kinds of the said seedling, it is good to cultivate from several months to several years. Fertilizer is given beforehand and / or at an appropriate timing after planting.

  The roots R, R, ... of the seedling Bb for transplanting grow sufficiently densely in the nursery box 10, and are removed from the plurality of pores 14, 14, ... (see both Fig. 8) opened in the bottom plate 12 of the nursery box 10. When a sufficient number of the plants have been extended, as shown in FIG. 1 (e), the bottom plate 12 and the planting seedlings Bc grown on the bottom plate 12 form the peripheral wall 11 of the seedling box 10 (see FIG. 1 (d)) To remove the afforestation soil S2. At this time, a plurality of roots R, R,... Possessed by the planting seedlings Bc are three-dimensionally entangled according to the shape of the nursery box 10 to form a three-dimensional structure RT. Further, the plurality of roots R, R, ... penetrate through the pores 14, 14, ... of the bottom plate 12, and the roots R, R, ... and the bottom plate 12 having a predetermined strength are integrally coupled. The above-described structure of the three-dimensional structure RT is maintained. In the present invention, one or more bars pass through the three-dimensional structure RT of the roots R, R,.

  If the length of the root R, R, ... of the planting seedling Bc and the length of the part of the bottom plate 12 penetrating through the pores 14, 14, ... is longer than appropriate, the part should be cut to the appropriate size. Good to do. By this, in the operation | work which carries out fixed planting of the seedling Bc for fixed planting so that it may mention later, it can prevent that the seedling Bc for fixed planting floats, and can set the seedling Bc for fixed planting reliably. On the other hand, since the depth of the soiling soil S2 in the nursery box 10 is substantially the same as the depth of the soiling soil S2 on the artificial ground G described later, the roots of the seedlings taken out from the nursery box 10 are almost cut. It does not need to be integrated, and the vitality of the seedlings can be maintained.

  Fig. 2 (f-1) is a front view of the bottom plate 12 and the planting seedlings Bc shown in Fig. 1 (e), and Fig. 3 (f-2) is a bottom plate 12 and for planting shown in Fig. 1 (e). It is a side view of seedling Bc. In addition, the same number is attached | subjected to the part corresponding to the part shown in FIG.1 (e) in FIG.2 (f-1) and FIG.3 (f-2).

  For example, when the seedling for planting Bc is obtained using the rectangular nursery box 10 as shown in FIG. 8, the short side of the bottom plate 12 as shown in FIG. 2 (f-1) and FIG. 3 (f-2) In the longitudinal direction of the three-dimensional structure RT of roots R, R, ... at positions respectively separated by appropriate distances from both short side edges of the bottom plate 12, It is pierced as close to 12 as possible. Here, the bar 30 is made of a material having a required strength, such as resin or metal, and both ends of the bar 30 from the three-dimensional structure RT are appropriately selected when the three-dimensional structure RT is penetrated. It has a length dimension that protrudes by a dimension. For example, when the short side length of the bottom plate 12 is 36 cm, the length of the bar 30 is preferably about 90 cm. In such a case, a bar 30 with a diameter of about 8 mm can be used.

  The length and diameter of the rod 30 may be appropriately determined in accordance with the height dimension of the planting seedling Bc, the height dimension in which the planting seedling Bc grows and the outer dimension of the bottom plate 12, and the root R, The number of bars 30 to be penetrated through the three-dimensional structure RT of R,... Is also appropriately determined according to the height dimension of the planting seedling Bc, the height dimension at which the planting seedling Bc grows and the outer size of the bottom plate 12. For example, in the case where the height dimension at which the planting seedlings Bc grow is about 50 cm or less, it is sufficient to use one rod 30, but the height dimension of the planting seedlings Bc is, for example, about 2 m In the case of exceeding four, it is recommended to use four bars 30, 30, 30, 30 crossed on the bottom plate 12 in a grid shape.

  On the other hand, as shown in FIG. 4 (g), the foundation of the greening system is constructed on the roof of a building or on an artificial ground G such as a veranda or a sidewalk.

  That is, the waterproof layer 1 is provided in the greening area on the artificial ground G. The waterproof layer 1 is formed by, for example, expanding a resin sheet having water impermeable property such as a rubber material on the artificial ground G, and when using a resin sheet, substantially the entire back surface of the resin sheet is used. Stick on the surface of artificial ground G.

  The periphery of the waterproof layer 1 is surrounded by, for example, an annular frame 2 formed by molding a lightweight concrete material, and a drainage channel 21 extends in one side of the frame 2. In addition, the height dimension of the waterproof layer 1 mentioned above is made to incline so that it may become low gradually toward one side from the other side of this frame part 2, and the water and rain water supplied in the frame part 2 are waterproof layer 1 It is guided into the drainage 21 according to the inclination of this, and is discharged by the drainage 21 from the frame 2 to the outside.

  A promenade 4 to be described later can be formed in an appropriate area on the waterproof layer 1, but when forming such a promenade 4, a plurality of, for example, wave plate members are used in a portion crossing the above-mentioned inclination of the waterproof layer 1 The water passages 3 (, 3,...) Are provided at appropriate places following the above-mentioned inclination of the waterproof layer 1 to secure drainage to the drainage channel 21. Then, a support member formed by forming, for example, a welding wire mesh in a U shape is externally fitted to the water flow passage 3 (, 3,...), And water permeability is provided on the water flow passage 3 (, 3,. The walkway 4 is formed using a lightweight concrete material or the like.

  On the other hand, the area other than the promenade 4 on the waterproof layer 1 is made into a soil so that the greening soil S1 described later has a depth of about 10 mm to about 30 mm. A resin net member 5 having a grid size of about 20 mm to about 30 mm is provided on the surface of the greening soil S1, and the edge of the net member 5 is formed on the waterproof layer 1 and / or the frame 2. It is fixed.

  Next, as shown in FIG. 5 (h), the bottom plate 12 and the planting seedlings Bc are placed at appropriate positions on the net member 5, and the three-dimensional shape of the roots R, R,. During the structure RT, the net members 5 are engaged with and fixed to both ends of the rods 30, 30 penetrating in parallel postures and projecting from the three-dimensional structure RT. As a result, the bottom plate 12 is firmly held between the bars 30, 30 and the net member 5, and the bottom plate 12 is fixed on the net member 5. As described above, the three-dimensional structure RT consisting of roots R, R, ... of the planting seedlings Bc is integrally connected to the bottom plate 12, so that the planting seedlings Bc including the three-dimensional structures RT are also through the bottom plate 12 It is fixed to the net member 5. Thus, the rods 30, 30 function as locking members that lock the bottom plate 12 to the net member 5. The rods 30, 30 may be engaged and fixed to the net member 5 by hooking the net members 5 at both ends of the bars 30, 30, or by using a linear member such as a string or a strip. Both ends of the bars 30, 30 may be engaged and fixed to the net member 5. Furthermore, these may be combined.

  Moreover, long connection members (linear members), such as a string material made of artificial fiber or a natural fiber, or a metal strip made of natural fiber between the trunk of the planting seedling Bc and the net member 5 as necessary. Since 35, 35, 35, 35 are expanded, it is possible to further prevent the overturning of the planting seedling Bc due to wind and rain. Note that the connecting members 35, 35,... Can be stretched in at least two different directions, but may be stretched in three different directions, or in four directions orthogonal to each other as shown in FIG. 5 (h). It goes without saying that the connecting members 35, 35,... May be expanded in four or more different directions.

  Thus, when the fixing operation of the planting seedling Bc including the three-dimensional structure RT and the bottom plate 12 to the net member 5 is completed, the soiling soil S1 on the net member 5 is brought to a suitable depth. Then, a three-dimensional structure RT consisting of roots R, R,... Of planting seedlings Bc is embedded in the revegetation soil S1. The depth of the afforestation soil S1 in this afforestation system can be made different depending on the place where the afforestation system is to be applied. For example, in the case of construction on the roof of a building, the depth is about 50 mm to 70 mm. As a result, the load per unit area of the greening system is 60 kg or less, and the legal standard for rooftop greening can be satisfied. On the other hand, when the greening system is to be installed on the sidewalk, for example, because there is no legal standard as described above, it can be determined appropriately according to the condition of the construction environment. For example, it can be set to an appropriate depth of about 50 mm to about 150 mm.

  On the other hand, even if the soiling soil S1 is thus shallow and the roots R, R, ... of the planting seedlings Bc are not sufficiently entangled in the net member 5, the planting seedlings Bc and the bottom plate as described above 12 can be fixed to the net member 5, and even if it is a planting seedling Bc which is about one year or less after planting, it is possible to sufficiently prevent the overturning due to wind and rain.

Here, the above-mentioned greening soils S1 and S2 will be further described.
As described above, the greening soils S1 and S2 are mainly composed by mixing agate and clay in a predetermined ratio, and the specific gravity thereof is less than 1. Needless to say, the revegetation soil can contain compositions other than straw and clay. A porous natural stone or artificial stone having multiple open cells, that is, a multi-connected porous stone can be used as a pebble, such as perlite made of bola earth, or pearlite and rosin, etc. The diameter should be approximately 2 mm or more and 4 mm or less.

  On the other hand, although it does not specifically limit as a clay used for soils S1 and S2 for tree planting, it is good to refrain from use of what formed the aggregate structure like a red ball soil, or to use, after destroying an aggregate structure.

  Thus, although the soils S1 and S2 for revegetation according to the present invention are configured to include the mulberry and the clay mixed in a predetermined ratio, the constituents of the glaze do not elute from the mulberry, and the clay is Because it is a natural product, it is safe for the environment. On the other hand, while clay is excellent in the ability to retain fertilizer, it does not have adsorption of specific nutrients such as adsorption of phosphorus by aluminum, so that fertilization management is easy.

  Further, the ratio of mixing the mulberry with the clay is different between that at the time of raising the seedlings and that at the time of planting of the above-described artificial ground revegetation system. That is, in the greening soil S1 on the artificial ground G, the ratio of the weir and the clay to be mixed is 21% by mass to 38% by mass, preferably 25% by mass to 36% by mass, More preferably, it is 28 mass% or more and 33 mass% or less.

  When the proportion of clay mixed in the revegetation soil S1 is less than 21% by mass, the water permeability of the revegetation soil is high but the water retention capacity is weak, and in addition to the need for increasing the amount of watering, As the cultivation period reached about 3 years, apparent growth defects were observed in the planted trees because the cultivation period was insufficient. On the other hand, when the ratio of the clay to be mixed with the revegetation soil S1 exceeds 38% by mass, the water retention capacity of the revegetation soil S1 becomes excessive, so that a high temperature failure occurs at the end of the rainy season. On the other hand, when the proportion of clay mixed in the soil for planting S1 is 21% by mass to 38% by mass, the water holding capacity and permeability of the planting soil S1 are well-balanced, and the required soil retention ability is also possessed. Therefore, planted trees can be cultivated for a long time without causing poor growth and high temperature damage.

  On the other hand, when the ratio of the clay to be mixed with the revegetation soil S1 is 25% by mass or more, the water holding capacity and the fertilization ability of the revegetation soil S1 are improved, so that the plants can be favorably grown. Moreover, when the ratio of the clay mixed with soil S1 for tree planting is 36 mass% or less, the hydraulic power of the said soil soil for tree S1 can be maintained highly, and the root of the planted plant can be kept healthy.

  Furthermore, in the case where the ratio of clay mixed in the soil for planting S1 is 28 mass% or more and 33 mass% or less, the balance between the water holding capacity and the water permeability of the soil for soiling S1 is good, and for many years Plants can be grown well. Moreover, not only the high temperature disorder at the time of the rainy season dawn can be avoided, but freezing does not occur in the soil for planting S1 even in winter, and the planted plants can be protected.

  By the way, when growing a seedling with the nursery box 10, since the said nursery box 10 can be moved freely, temperature management and water management can be implemented freely. On the other hand, the higher the ratio of mixing clay with high fertility, the better the growth of plants. Therefore, the greening soil S2 filled in the nursery box 10 is made larger than the ratio of the clay constituting the greening soil S1 used on the artificial ground G. By this, the growth of a seedling becomes favorable and a strong seedling can be obtained.

  On the other hand, even in the case of the soiling soil S2 used in the nursery box 10, when the proportion of clay to be mixed is 40% by mass or more, the water content in the soiling soil S2 becomes excessive, which hinders the growth of seedlings. Since the proportion of clay is less than 40% by mass, the revegetation soil S2 is used.

  Based on the above, when the inventor further studied, the proportion of clay constituting the soiling soil S1 laid on the artificial ground G is approximately 30 mass%, and the soil for reforestation filled in the nursery box 10 When the ratio of the clay which comprises S2 is about 32 mass%, the knowledge that the growth of the plant planted in soil S1 for afforestation was still more suitable was acquired. That is, about the soil S1 for greening laid on the artificial ground G, when the ratio of clay is about 30 mass%, the planted plant can be grown best. This is a balance between the water holding capacity and the water permeability of the soiling soil S1 and the balance between the water holding ability and the growth ability of the planted plant on the artificial ground G. Not too late, it is considered to be done very well.

  On the other hand, in the case of the greening soil S2 to be filled in the nursery box 10, the permeability of the greening soil S2 filled can be made higher by adjusting the holding condition of the nursery box 10. The seedling can be grown larger and more quickly by improving the soil retention ability using the revegetation soil S2 in which the proportion of clay is approximately 32% by mass.

  Next, as shown in FIG. 6 (i), the work of finishing the greening system is performed. That is, the water supply hose 6 having a plurality of fine holes (not shown) opened at appropriate intervals in the longitudinal direction is disposed at an appropriate position on the greening soil S1 customer soiled in the waterproof layer 1 Water is dropped from each of the fine holes of the water supply hose 6. Also, instead of the water supply hose 6 or together with the water supply hose 6, micro sprinklers 7, 7 ... that perform a relatively small amount of watering are disposed at appropriate positions on the greening soil S1, and each micro sprinkler 7 is provided. , 7,... Are designed to operate for a predetermined time at each time preset by the controller 8.

Then, operate the water supply hose 6 and / or the micro sprinkler 7, 7, ... as described above, for example, watering of an amount of about 200 ml or more and about 500 ml or less per 1 m ² per minute, or about 15 minutes every day in summer Conduct in the winter, and carry out for about 10 minutes every 3 days. Fertilizer is given beforehand and / or at an appropriate timing after planting.

  Thus, planting seedlings Bc, Bc,... Are grown for about 3 months to about 1 year.

  FIG. 7 is a partial longitudinal cross-sectional view of the present greening system after cultivating the fixed planted plant for a suitable period of time. In the figure, parts corresponding to the parts shown in FIG. 6 (i) are assigned the same reference numerals and the explanation thereof is omitted.

  As shown in FIG. 7, the roots R, R, ... of the planting seedlings Bc, Bc, ... extend in the greening soil S1, and become entangled in the net member 5, and adjacent planting seedlings Bc, The roots R, R, ... of Bc, ... are intertwined with one another. By this, not only the seedlings for stationary planting Bc, Bc,... Are supported by the net member 5, but the seedlings for stationary planting Bc, Bc,... Mutually support each other, thus further preventing overturning due to wind and rain. Can.

  In this embodiment, both end portions of the rods 30, 30 serving as the locking members are parallel to each other in the three-dimensional structure RT of roots R, R, ... of the planting seedling Bc. Although the case where it penetrates in a mode which protrudes from RT was explained, the present invention is not limited to this, and it may be a mode in which one end portion of both bars 30 and 30 protrudes from solid structure RT, and both bars The ends of the members 30, 30 may be inserted into the three-dimensional structure RT. In the latter case, the cords 30 and 30 are engaged with the net member 5 by a cord-like member. On the other hand, a plurality of bars 30, 30, ... may be inserted into the three-dimensional structure RT in a posture in which they cross each other. By this, the bottom plate 12 can be locked to the net member 5 in the longitudinal direction and the lateral direction, and the bottom plate 12 can be further firmly locked to the net member 5. Therefore, even if the planting seedling Bc is relatively high in height, it is possible to prevent the overturning due to wind and rain.

  In this embodiment, although the case where bars 30 and 30 are used as the locking member is described, the present invention is not limited thereto, and for example, a string made of resin or a strip made of metal having high anti-corrosion ability A locking member such as a material can be applied. In this locking member, the bottom plate 12 can be firmly locked to the net member 5 by fixing one end to the bottom plate 12 and fixing the other end to the net member 5.
