Description

The present invention relates to a cultivation bench for filling soil and cultivating plants, an elevated cultivation structure using the cultivation bench, and a method for forming a medium using the cultivation bench.

Conventionally, cultivated plants such as fruits and vegetables are installed at a waist-high position when cultivated in a predetermined cultivation space such as a vinyl house, and are planted and cultivated on a cultivation bench filled with soil. In particular, cultivated plants including some crops such as strawberries are suitable for elevated cultivation in various aspects such as management and harvesting, so they are installed at a position higher than the ground surface and are used for elevated cultivation. Cultivation benches are often used.

For example, Patent Document 1 discloses an elevated cultivation device for cultivating strawberries and the like at a high place. Hereinafter, in the paragraph, the reference numerals of Patent Document 1 are shown in parentheses. The elevated cultivation device (1) supports a cultivation tank (3) in which a medium (3b) is wrapped with a non-woven fabric (3a) between two shafts (2, 2A) installed in a parallel state, and seedlings are placed in the cultivation tank. (4) is a device for planting and cultivating. The cultivation tank (3) is obtained by inserting, for example, a medium (3b) in which peat moss and rice husk charcoal are mixed into a tubular non-woven fabric (3a) and wrapping it in the non-woven fabric. The non-woven fabric (3a) is formed into a cylindrical shape by being sewn along the longitudinal direction of the shaft (2, 2A), or both upper and lower strip-shaped non-woven fabrics are sewn at both ends to insert a solid material. Is formed in. This cultivation tank (3) is used for planting, growing and cultivating strawberry seedlings (4).

Japanese Unexamined Patent Publication No. 2010-148376

In the cultivation of some crops such as strawberries, the cultivated plants are planted and cultivated in rows near the side edges of the medium in order to grow the cultivated plants so that the fruits hang down laterally. In particular, the root system of strawberry seedlings, which is one of the cultivation targets, has a root structure consisting of a thick adventitious root group and a thin lateral root group branched from these, and the lateral roots spread laterally and grow. When cultivating such a plant, in the conventional cultivation tank (cultivation bench) as in Patent Document 1, the non-woven fabric hangs down in a semicircular shape to form the wall portion of the cultivation tank, and the cultivation layer is at the bottom. It narrows as it gets closer. Therefore, the problem is that the lateral roots of the cultivated plant hit the inner wall surface of the cultivation tank to hinder its development, or the lateral roots tend to grow along the inner surface. That is, the conventional cultivation bench may accelerate the aging and necrosis of the roots of specific cultivated plants such as strawberries due to the tank structure, and may cause poor development of seedlings and delay of survival after planting. ..

Further, the cultivation bench 100 has a predetermined height so as to accommodate a soil having a depth sufficient for cultivating a predetermined cultivated plant, and is cultivated in two rows in a width direction orthogonal to the longitudinal direction. It is wide enough to grow plants. In this specification, the longitudinal direction and the width direction are defined as described above, but the definition is not based on the dimensions of the sides. That is, in the present specification, the longitudinal direction indicates only one direction in which the cultivation bench is extended, and the width direction indicates only one direction orthogonal to it. Therefore, in the present invention, it goes without saying that the longitudinal side may have the same length as the width side, or the longitudinal side may be shorter than the width side.

The cultivation bench 100 shown in FIGS. 1 to 3 has a narrow upward opening and an expanded bottom for accommodating hilling soil, and has a cultivation form suitable for cultivating cultivated plants such as strawberry seedlings. ing. On the other hand, the cultivation bench 100 shown in FIGS. 4 to 6 has an opening facing upward and has a soil filling form suitable for filling the soil. The cultivation bench 100 of the present embodiment is configured to be mutually deformable from the cultivation form shown in FIGS. 1 to 3 to the soil filling form shown in FIGS. 4 to 6.

The cultivation bench 100 includes a bottom wall portion 101 extending in the longitudinal direction and a pair of side wall portions 102, 102 rising from both sides facing each other in the width direction of the bottom wall portion 101, and forms a soil accommodating portion 103 inside. .. The hilling storage unit 103 is a space for accommodating and holding the hilling soil for cultivation, and has an upper opening. Further, both ends of the cultivation bench 100 (or the soil accommodating portion 103) in the longitudinal direction are closed by a sheet material (as a front wall and a rear wall) extending between the pair of side wall portions 102 and 102 (not shown). ing.

The cultivation bench 100 further includes a pair of bottom shaft members 104, 104, a pair of top shaft members 105, 105, and a plurality of side shaft members 106. Each shaft member was formed as a pipe member having a circular cross section. The pair of bottom shaft members 104, 104 and the pair of top shaft members 105, 105 extend parallel to each other in the longitudinal direction. The pair of bottom shaft members 104, 104 are connected to both side surfaces of the bottom wall portion 101 facing in the width direction and the lower end sides of the pair of side wall portions 102, 102, respectively. The pair of top shaft members 105 and 105 are connected to the upper end sides of the pair of side wall portions 102 and 102, respectively. Further, the bottom shaft member 104 and the top shaft member 105 arranged on the same side in the width direction are rotatably connected by the side shaft member 106 extending in the height direction. That is, the top shaft member 105 can be rotated and displaced with the bottom shaft member 104 as the central axis. The bottom shaft member 104 and the top shaft member 105 are connected by the side shaft member 106 at a plurality of points in the longitudinal direction. Here, the lengths of the bottom shaft member 104 and the top shaft member 105 correspond to the length of the cultivation bench 100. Further, the distance between the pair of bottom shaft members 104, 104 and the pair of top shaft members 105, 105 corresponds to the bottom width and the opening width of the cultivation bench 100, respectively. That is, a pair of bottom shaft members 104, 104, a pair of top shaft members 105, 105, and a plurality of side shaft members 106 are assembled in a rectangular frame shape to form the skeleton of the cultivation bench 100.

Further, a long leg member 15 is fixed to each bottom shaft member 104 (see FIG. 18). The leg member 15 is placed on the ground surface as a base having a predetermined height. Then, the leg member 15 supports the opening surface of the soil accommodating portion 103 of the cultivation bench 100 at a position higher than the ground surface. By filling the soil accommodating portion 103 with the soil, the opening surface of the soil accommodating portion 103 becomes the medium surface.

In the cultivation bench 100 of the present embodiment, the bottom wall portion 101 and the side wall portion 102 are formed by covering the skeleton made of the shaft members 104, 105, and 106 from the inside with one flexible sheet material. That is, the bottom wall portion 101 is composed of a part of the sheet material provided between the pair of bottom shaft members 104 and 104, and each side wall portion 102 is provided between the bottom shaft member 104 and the top shaft member 105. It consists of a part of the sheet material. More specifically, the sheet material is stretched between the top shaft member 105 and the adjacent bottom shaft member 104 and between the pair of bottom shaft members 104, 104, and then the shaft members 104, 105. It is fixed to a plurality of C-shaped clips 109. Further, the sheet material is made of a water-permeable non-woven fabric and can also function as a drainage means. The sheet material may be provided in a loose state between the shaft members.

Further, the cultivation bench 100 further includes a plurality of fasteners 110 that connect the pair of side wall portions 102 and 102 to each other and fix the side wall portions 102 to the bottom wall portion 101 in a predetermined posture. The fastener 110 spans between the pair of top shaft members 105, 105 constituting the upper end sides of the pair of side wall portions 102, 102, holds the top shaft members 105, 105, and keeps the distance constant. In this way, by keeping the distance between the pair of top shaft members 105 and 105 constant by the fastener 110, the inclined posture of the pair of side wall portions 102 and 102 with respect to the bottom wall portion 101 is fixed at a predetermined inclination angle. To. In the present embodiment, the fastener 110 has two second side walls 102 (a straight line connecting the bottom shaft member 104 and the top shaft member 105) with respect to the bottom wall portion 101 (a straight line connecting the pair of bottom shaft members 104). It is configured to be fixed in the 1st and 2nd postures (1st and 2nd tilt angles).

As shown in FIGS. 1 to 3, in the cultivation bench 100 of the cultivation form, the pair of side wall portions 102 and 102 are inclined at a first inclination angle forming an acute angle with respect to the bottom wall portion 101 via the fastener 110. It is fixed to the first posture. The soil accommodating portion 103 becomes wider as it approaches the bottom wall portion 101. That is, the opening width of the hilling accommodating portion 103 is smaller than that of the bottom wall portion 101, and the hilling filling space extends outside in the width direction of the opening edge of the hilling accommodating portion 103. As described above, the capacity of the culture soil accommodating portion 103 when the inclination angle is acute is smaller than that when the inclination angle is obtuse or right angle, and the amount required for filling the soil is reduced. The first tilt angle is not limited, but is preferably in the range of about 50 degrees to about 80 degrees. In this range, the required opening width and depth of the soil accommodating portion 103 are reduced while reducing the capacity (the amount of soil to be filled) of the soil accommodating portion 103 so that the cultivated plants can be effectively cultivated with a relatively small amount of soil. It is possible to preferably secure the ridges and form a space in which the roots of the cultivated plant can sufficiently spread laterally. That is, in the cultivation bench 100 of the cultivation form, the opening facing upward is narrowed, the bottom where the soil is stored is expanded, and the strawberry seedlings are cultivated with a relatively small amount of soil (compared to the case where the inclination angle is large). Suitable for cultivating cultivated plants such as.

In the cultivation bench 100 of the cultivation embodiment of the present embodiment, the distance between the pair of bottom shaft members 104 and 104 is about 450 mm, and the distance between the pair of top shaft members 105 and 105 is not limited to the present invention. Is about 250 mm, the height of the top shaft member 105 (distance from the inner surface of the bottom wall portion 101 to the opening surface of the soil accommodating portion 103) is about 180 mm, and the first inclination angle is set to about 60 degrees.

As shown in FIGS. 4 to 6, in the cultivation bench 100 in the hilling-filled form, the pair of side wall portions 102 and 102 have a second inclination angle forming an obtuse angle with respect to the bottom wall portion 101 via the fastener 110. It is fixed to the inclined second posture. The soil accommodating portion 103 becomes wider as it approaches the opening. In the cultivation bench 100 of this hilling filling form, the opening width of the hilling accommodating portion 103 is larger than that of the bottom wall portion 101. A large amount of soil is required. Further, when a cultivated plant is planted in the vicinity of the side edge of the opening surface, the grown roots hit the wall surface of the side wall portion 102, and poor growth is likely to occur. That is, the cultivation bench 100 in the form of hilling filling is not suitable for cultivation of cultivated plants. On the other hand, the structure of the hilling accommodating portion 103, which becomes wider as it approaches the opening of the cultivation bench 100 in the hilling filling form, is advantageous when filling the hilling. More specifically, since the opening width is wider than that of the bottom wall portion 101, when the soil is filled in the soil accommodating portion 103 through the opening, the soil is filled on the bottom wall portion 101 without spilling. easy. Further, since the bottom wall portion 101 and the side wall portion 102 are bent at obtuse angles, it is possible to fill the culture soil accommodating portion 103 without gaps, and it is possible to prevent filling leakage when the culture soil is filled. That is, the cultivation bench 100 in the form of filling the soil is suitable for filling the soil because the opening facing upward is widened and there is no sharp portion inside.

In the cultivation bench 100 of the hilling filling form of the present embodiment, although the present invention is not limited, the distance between the pair of bottom shaft members 104 and 104 is about 450 mm, and the pair of top shaft members 105 and 105 have a distance of about 450 mm. The distance was about 678 mm, the height of the top shaft member 105 (distance from the inner surface of the bottom wall portion 101 to the opening surface of the hilling accommodating portion 103) was about 172 mm, and the first inclination angle was set to about 124 degrees. ..

As shown in FIGS. 3 and 6, when the fastener 110 is installed with respect to the pair of side wall portions 102, 102, the connecting shaft 121 extends horizontally to the opening surface of the soil accommodating portion 103 in the width direction thereof. A pair of connecting bodies 111 and 111 extend outward in the width direction on both sides, respectively.

In the cultivation bench 100 of the cultivation form, as shown in FIG. 3, the tip end side arm 113b is arranged at the lower limit position. As shown in FIG. 3, in the cultivation mode, the base end side arm 113a of each connecting body 111 is inclined upward from the horizontal direction at a predetermined inclination angle (about 10 degrees), and the opening surface of the soil accommodating portion 103 is formed. It extends away from. The tip end side arm 113b is tilted downward from the horizontal direction at an angle (about 45 degrees) larger than the tilt angle of the base end side arm 113a. By arranging the tip side arm 113b at the lower limit position, it is possible to reduce the amount of lateral protrusion of the tip side arm 113b so as not to interfere with the cultivation work.

In the cultivation bench 100 in the hilling-filled form, as shown in FIG. 6, the tip end side arm 113b is arranged at the upper limit position. As shown in FIG. 6, in the soil filling mode, the base end side arm 113a of each connecting body 111 is inclined upward from the horizontal direction at a predetermined inclination angle (about 10 degrees), and the opening of the soil accommodating portion 103. It extends away from the surface. The tip end side arm 113b is tilted downward from the horizontal direction at an angle (about 15 degrees) slightly larger than the tilt angle of the base end side arm 113a. That is, the arm portion 113 of the connecting body 111 is bent or bent so as to bulge upward to be separated from the opening surface of the soil accommodating portion 103, and on its side end side (tip side), it becomes an opening surface of the soil accommodating portion 103. It is down so that it is close. That is, the fastener 110 is arched between the pair of side wall portions 102 and 102 above the opening of the soil accommodating portion 103 (the upper portion of which is widened). By arranging the tip side arm 113b at the upper limit position, the distance between the pair of top shaft members 105 and 105 is maximized, which is more suitable for filling the soil.

Further, the first holding portion 114 and the second holding portion 115 of the connecting body 111 are provided in the vicinity of the base end and the vicinity of the tip end of the connecting body 111, respectively. That is, the first holding portion 114 is arranged so as to hold the top shaft member 105 at a position where the side wall portion 102 is inclined at the first obtuse angle forming an acute angle with respect to the bottom wall portion 101 (see FIG. 3). The 2 holding portion 115 is arranged so as to hold the top shaft member 105 at a position where the side wall portion 102 is inclined at a second inclination angle forming an obtuse angle with respect to the bottom wall portion 101 (see FIG. 6).

The first holding portion 114 is formed at the lower end portion of the base portion 112, and is composed of a C-shaped elastically deformable grip piece that is open downward. The first holding portion 114 is configured to open in a direction orthogonal to the longitudinal direction (or connecting shaft 121) of the arm portion 113 so that the top shaft member 105 can be held inside along the longitudinal direction of the cultivation bench 100. .. Further, the internal shape of the grip piece of the first holding portion 114 is oval, and as shown in FIG. 13, there is a play that allows the top shaft member 105 having a circular cross section to swing. The play allows the top shaft member 105 to tilt in the longitudinal direction with respect to the bottom shaft member 104 while the first holding portion 114 holds the top shaft member 105. That is, by arranging the top shaft member 105 inside the grip piece of the first holding portion 114, the first holding portion 114 can temporarily hold the top shaft member 105.

Here, as shown in FIG. 12, the connecting body 111 is combined with a regulating member 117 having a shape in which a semi-cylindrical wall (regulating portion) is combined with a rectangular flat plate-shaped bottom wall (pinching) and a regulating member 117. Further includes a semi-arc plate-shaped spacer 118 and a semi-cylindrical socket 119 which can be used. The regulating member 117 and the spacer 118 can be combined with each other to function as one component due to the unevenness relationship. The socket 119 has a semi-cylindrical wall 119a extending in the tubular axis direction and a flange 119b protruding radially outward from both ends thereof. The flange 119b may abut on the grip piece of the first holding portion 114 to restrict the movement of the connecting body 111 in the tubular axial direction. In the cultivation bench 100 of the cultivation form, the regulation member 117 is pushed together with the top shaft member 105 into the inside of the grip piece of the first holding portion 114, so that the tilt of the top shaft member 105 in the first holding portion 114 is selected. The top shaft member 105 is finally fixed by the first holding portion 114. Spacers 118 and sockets 119 may be used depending on the pipe diameter of the top shaft member 105.

FIG. 14 (a) shows a form of holding the top shaft member 105 having a relatively large diameter (for example, when an agricultural straight pipe having a diameter of 22.2 mm is used). Further, the connecting shaft 121 also has a similar diameter. As shown in FIG. 14A, by arranging the top shaft member 105 and the restricting member 117 inside the gripping piece of the first holding portion 114, there is no gap (play) and the movement of the top shaft member 105 moves. Be regulated. When the sheet material is thin, for example, less than 1 mm, the spacer 118 may be used in combination with the regulating member 117. Further, as shown in FIG. 14A, the connection portion 112a in which the connection shaft 121 is inserted has a large diameter cylinder portion on the front side (base end side) of the hole and an inner diameter on the back side (tip side). It consists of a cylinder. The connecting shaft 121 is fitted to the large-diameter cylinder portion and then fixed by the lock portion 112b.

On the other hand, FIG. 14 (b) shows a form of holding the top shaft member 105 having a relatively small diameter (for example, when an agricultural straight pipe having a diameter of 19.1 mm is used). Further, the connecting shaft 121 also has a similar diameter. As shown in FIG. 14B, a gap (play) is created by arranging the spacer 118 and the socket 119 in addition to the top shaft member 105 and the restricting member 117 inside the gripping piece of the first holding portion 114. It disappears and the movement of the top shaft member 105 is restricted. Here, the regulating member 117 and the spacer 118 are combined with each other on an uneven surface to form one member, and the socket 119 is mounted on the top shaft member 105 via the sheet material. Further, as shown in FIG. 14B, the connecting shaft 121 is pushed to the depth of the connecting portion 112a, fitted to the small diameter cylinder portion, and then fixed by the locking portion 112b.

The second holding portion 115 is formed at the tip end portion of the arm portion 113, and is composed of a U-shaped elastically deformable grip piece opened on the opposite side (toward the proximal end) of the distal end side arm 113b in the extending direction. The second holding portion 115 opens in a direction orthogonal to the longitudinal direction (or connecting shaft 121) of the arm portion 113, and is configured to be able to hold the top shaft member 105 inside along the longitudinal direction of the cultivation bench 100. .. Further, the internal shape of the grip piece of the second holding portion 115 is oval, and as shown in FIG. 6, there is a play that allows the top shaft member 105 having a circular cross section to swing. Due to the play, it is allowed that the top shaft member 105 is inclined in the longitudinal direction with respect to the bottom shaft member 104 while the second holding portion 115 holds the top shaft member 105. That is, by arranging the top shaft member 105 inside the grip piece of the second holding portion 115, the second holding portion 115 can temporarily hold the top shaft member 105. In the cultivation bench 100 in the hilling-filled form, since it is not necessary for the second holding portion 115 to actually fix the top shaft member 105, the regulating member 117 or the like is not inserted into the second holding portion 115.

That is, the fastener 110 of the present embodiment includes a pair of first holding portions 114, 114 and a pair of second holding portions 115, 115, and a pair of top shaft members is selected by selecting the holding portions according to the purpose. By holding the 105, 105, the side wall portions 102, 102 can be held at two inclination angles with respect to the bottom wall portion 101. Further, since the first holding portion 114 and the second holding portion 115 hold (temporarily fix) the top shaft member 105 so as to allow the top shaft member 105 to tilt, the first holding portion 114 or the second holding portion While holding the top shaft member 105 at 115, the top shaft member 105 can be tilted for changing hands.

Next, a method of filling the cultivation bench 100 of the present embodiment with soil to form a culture medium for cultivation will be described. Here, in the cultivation bench 100 of the initial form, the first holding portion 114 holds the top shaft member 105, but the regulating member 117 is not inserted in the first holding portion 114. Alternatively, when the regulating member 117 is inserted into the first holding portion 114, the regulating member 117 is removed from the first holding portion 114 to release the fixing.

First, the pair of side wall portions 102, 102 are tilted at a position where each side wall portion 102 of the cultivation bench 100 is inclined at a second inclination angle forming an obtuse angle with respect to the bottom wall portion 101. More specifically, for each of the plurality of fasteners 110, the top shaft member 105 is sequentially removed from the first holding portion 114, and the top shaft member 105 is rotated outward in the width direction.

Second, the pair of side wall portions 102, 102 are held in the second posture inclined at the second inclination angle so that the opening width of the soil accommodating portion 103 is wider than the width of the bottom wall portion 101. More specifically, for each of the plurality of fasteners 110, the top shaft member 105 is sequentially rotated outward in the width direction and then inserted into the second holding portion 115. As shown in FIG. 15, since the top shaft member 105 is allowed to tilt in the first holding portion 114 and the second holding portion 115 (see FIG. 13), the holding portion 114 at another position in the axial direction, It is possible to incline and operate the top shaft member 105 while holding the top shaft member 105 in the 115. Therefore, in this step, the top shaft member 105 is prevented from falling during the work.

Thirdly, the hilling storage unit 103 is filled with the hilling 11. After the cultivation bench 100 is displaced to the hilling filling form, as shown in FIG. 16A, a predetermined amount of hilling is filled from the widened opening of the hilling accommodating portion 103. At this time, since the opening of the hilling accommodating portion 103 is widened, it is easy to fill the hilling 11 without spilling, and the bottom wall portion 101 and the side wall portion 102 have obtuse angles, so that the hilling soil 11 is spilled. It is easy to evenly fill the hilling 11 without creating a gap in the accommodating portion 103. Further, the fastener 110 is arched above the opening of the soil accommodating portion 103 while holding the pair of top shaft members 105, 105 by the second holding portions 115, 115, whereby the soil 11 is placed near the opening surface. Even if it is filled up to, the fastener 110 is prevented from being buried in the ground during the filling of the soil. Since the cultivation bench 100 in the culture soil filling form has a larger capacity (volume from the inner surface of the bottom wall portion 101 to the opening width) of the culture soil accommodating portion 103 than the cultivation form, the cultivation soil 11 is about 60 to 70%. It is sufficient to fill at the filling rate.

Fourth, the pair of side wall portions 102, 102 are tilted at a position where each side wall portion 102 of the cultivation bench 100 is inclined at the first inclination angle with respect to the bottom wall portion 101. After the filling of the predetermined amount of the hilling 11 is completed, as shown in FIG. 16B, for each of the plurality of fasteners 110, the top shaft member 105 is sequentially removed from the second holding portion 115, and the top shaft member is removed. Rotate 105 inward in the width direction. Similarly, since tilting of the top shaft member 105 is allowed in the first holding portion 114 and the second holding portion 115 (see FIG. 13), the top is in the holding portions 114, 115 at other positions in the axial direction. It is possible to operate the top shaft member 105 by tilting it while holding the shaft member 105.

Fifth, each side wall portion 102 is fixed to the bottom wall portion 101 in a first posture inclined at a first inclination angle. As shown in FIG. 16 (c), for each of the plurality of fasteners 110, the top shaft member 105 is sequentially rotated inward in the width direction and then inserted into the first holding portion 114. After the top shaft member 105 is held by the first holding portion 114 for all the fasteners 110, the top shaft member 105 and the first holding portion 114 are finally fixed. Specifically, as shown in FIG. 17, the combination of the regulating member 117 and the spacer 118 is driven into the gap between the first holding portion 114 and the top shaft member 105 along the axial direction of the shaft member. The regulating member 117 and the spacer 118 are inserted into the first holding portion 114. If the sheet material is thick (for example, 1 mm or more), the spacer 118 is omitted (see FIG. 14A), or if the top shaft member 105 has a small diameter, the socket 119 is used. Is added (see FIG. 14 (b)). Therefore, in the process, the gap in the first holding portion 114 is closed by the regulating member 117, and each side wall portion 102 can be fixed to the bottom wall portion 101.

Through the above series of steps, a cultivation bench 100 in a cultivation form in which the soil 11 is filled is configured, and as a result, a medium for the cultivated plant can be formed.

Next, an elevated cultivation structure 10 in which strawberry seedlings 12 are planted as an example of cultivated plants will be described with respect to the cultivation bench 100 accommodating the cultivation soil 11. FIG. 18 is a schematic perspective view of the elevated cultivation structure 10. FIG. 19 is a front view schematically showing the elevated cultivation structure 10. It goes without saying that the cultivated plant of the elevated cultivation structure 10 is not limited to the strawberry seedling 12, and any plant may be cultivated.

In the elevated cultivation structure 10 of the present embodiment, the cultivation bench 100 is elevated by the leg members 15, and the medium surface is formed at a position higher than the ground surface (preferably at the height of the waist). As shown in FIG. 18, a plurality of strawberry seedlings 12 are planted in the longitudinal direction in the vicinity of both ends in the width direction of the cultivation bench 100. That is, the strawberry seedlings 12 are planted in two rows almost linearly along the longitudinal direction. Further, a water pipe 16 for heating is arranged on the surface of the medium.

As shown in FIG. 19, the cultivation bench 100 is filled with the soil 11 up to the opening surface of the soil accommodating portion 103 without any gap. The hilling accommodating portion 103 has a wider space as it approaches the bottom wall portion 101 from the opening surface. In this elevated cultivation structure 10, the roots of the strawberry seedlings 12 planted in the vicinity of the opening edge grow laterally because the soil accommodating portion 103 extends outside in the width direction of the opening edge of the soil accommodating portion 103. Space is secured. Therefore, as shown in the figure, the roots of the strawberry seedlings 12 can grow naturally on the lateral side in the width direction.

Further, in the elevated cultivation structure 10 of the present embodiment, the arm portion 113 of each connecting body 111 of the fastener 110 protrudes laterally outward in the width direction from the opening of the soil accommodating portion 103. At this time, the tip side arm 113b of the arm portion 113 rotates inward in the width direction and is close to the side wall portion 102 inclined inward in the width direction, so that the amount of protrusion of the bottom wall portion 101 to the outside in the width direction is large. Is reduced, and it is suppressed that it interferes with work such as cultivation and harvesting. Further, a plurality of wires 123 as plant supporting means are extended in the longitudinal direction on the support portion 116 on the upper surface of the arm portion 113. Each wire 123 is stretched over a support portion 116 of a plurality of fasteners 110 installed in the longitudinal direction. As shown in FIG. 19, the strawberry fruit hanging laterally from the strawberry seedling 12 is supported by a plurality of wires 123. By the wire 123, the weight load due to the strawberry fruit applied to the root of the strawberry seedling 12 can be reduced, and the stem and the fruit stalk of the strawberry seedling 12 can be prevented from breaking. The plant supporting means is not limited to the wire 123, and may be substituted by, for example, a sheet such as a non-woven fabric or a net. Alternatively, a sheet or a net may be combined with the wire 123.

Hereinafter, the action and effect of the cultivation bench 100 according to the present invention will be described.

In the cultivation mode, the cultivation bench 100 of the present embodiment is fixed to the first posture in which the pair of side wall portions 102, 102 are inclined at the first inclination angle forming an acute angle with respect to the bottom wall portion 101, so that the soil is cultivated. It has a structure in which the accommodating portion 103 becomes wider as it approaches the bottom wall portion 101. Due to the hilling structure of the soil accommodating portion 103, even when a cultivated plant (strawberry seedling 12) is planted and cultivated near the side edge of the medium, a soil space for roots to spread laterally and grow is secured. .. Further, since the hilling accommodating portion 103 has a structure that becomes wider as it approaches the bottom wall portion 101, the opening width and the hilling depth required for cultivation are secured, and the necessary hilling can be obtained without hindering the growth of the cultivated plants. The amount can be reduced. Therefore, the cultivation bench 100 of the present embodiment can effectively suppress the occurrence of root developmental disorders and root winding phenomena as compared with the conventional case, and can grow the cultivated plants more naturally.

The present invention is not limited to the above embodiment, and various embodiments and modifications can be taken. Hereinafter, a plurality of modifications of the present invention will be described.

(1) The cultivation bench of the present invention is not limited to the above embodiment, and may take various forms. For example, in the cultivation bench 200 shown in FIG. 20, each connecting body 211 of the fastener 210 is composed of only the base portion 212 and the first holding portion 214. That is, in the cultivation bench of the present invention, the fastener does not have to be provided with the second holding portion, and the fixing means for fixing the posture of the side wall portion with respect to the bottom wall portion can be arbitrarily selected. Similar to the above embodiment, the cultivation bench 200 may take a cultivation form in which the soil accommodating portion 203 becomes wider as it approaches the bottom wall portion 201. Further, in the cultivation bench 200, after releasing the holding of the top shaft member 205 from the first holding portion 214, the side wall portion 202 is tilted with respect to the bottom wall portion 201, and the side wall portion 202 is manually tilted in an arbitrary inclined posture. By holding, the cultivation bench 200 can be transformed into a soil filling form.

(2) The cultivation bench of the present invention is not limited to the above embodiment, and may take various forms. The wall portion of the cultivation bench is not limited to a planar shape, and may be a bent surface, a curved surface, or the like as long as it is included in the technical scope of the present invention. For example, in the cultivation bench 300 shown in FIG. 21, a central shaft member 308 is provided between the bottom shaft member 304 and the top shaft member 305. The outer wall portion of the cultivation bench 300 is formed by stretching the sheet material on the bottom shaft member 304, the middle shaft member 308, and the top shaft member 305. In particular, a first wall portion is formed between the pair of bottom shaft members 304, a second wall portion is formed between the top shaft member 305 and the middle shaft member 308, and the middle shaft member 308 and the bottom portion are formed. A third wall portion is formed between the shaft member 304 and the shaft member 304. Here, the bottom wall portion (301) of the present invention may be interpreted not only as a first wall portion but also as a bent wall portion in which a first wall portion and a third wall portion are combined. Further, the side wall portion (302) of the present invention may be interpreted not only as a second wall portion but also as a bent wall portion in which a second wall portion and a third wall portion are combined. Regardless of which interpretation is used, in the cultivation bench 300, in the cultivation mode, the pair of side wall portions 302 and 302 are on the bottom wall portion 301 side, and the soil accommodating portion 303 is on the bottom wall portion 301. It is characterized in that it is fixed to the first posture, which becomes wider as it approaches.

(3) The cultivation bench of the present invention is not limited to the above embodiment, and may take various forms. The bottom wall portion and the side wall portion of the present invention are not limited to the flexible sheet material stretched between the top shaft member and the bottom shaft member. For example, the sheet material may be a hard synthetic resin plate bonded to the top shaft material and the bottom shaft material, a sheet metal, or the like. Further, the bottom wall portion and the side wall portion may be formed by rotatably connecting the plate members without forming the shaft member.

(4) The cultivation bench of the present invention is not limited to the above embodiment, and may take various forms. The cultivation bench of the present invention may be configured so that the pair of side wall portions are fixed so as not to tilt with respect to the bottom wall portion.

(5) The cultivation bench of the present invention is not limited to the above embodiment, and may take various forms. Although the cultivation bench of the above embodiment is configured for elevated cultivation, it may be used so that the bottom wall portion is directly placed on the ground surface by omitting the leg members.
