Description

  The present invention relates to a cassette-type seedling growing container, and more particularly to a cassette-type seedling growing container capable of growing a large amount of seedlings having a healthy root pot without abnormal root deformation such as root winding.

  The seedlings are not grown in a dedicated container (pot), but are called so-called multi-cavity containers (hereinafter referred to as “containers”) in which vertical cone-shaped recesses (cavities) are formed in a tray, for example. It is known to grow a large amount of seedlings with an apparatus (see, for example, Patent Document 1). A seedling grown in the pot is called a “pot seedling”, and a seedling grown in the container is called a “container seedling”. Each container seedling is grown in the cavity.

  Pot seedlings and container seedlings differ not only in the growth container but also in many ways. First, the shape of the root pot is different. The pot seedling has a horizontally long and vertically short shape, whereas the container seedling has a horizontally short and vertically long shape. Therefore, the container seedling has a moldability in which the root pot is less likely to collapse than the pot seedling. For this reason, container seedlings are easy to transplant into soil and are also called “plug seedlings”. Further, the capacity of the pot is about 450 cc, whereas the capacity of the cavity is about 150 cc. Furthermore, the culture medium (culture soil) used for raising seedlings is based on soil for pot seedlings, while it is based on organic media such as coconut husk and peat moss for container seedlings. As a result, the container seedling has the advantage that it is smaller and lighter than the pot seedling, is easy to handle and can be easily transplanted to the soil.

  The biggest difference between container seedlings and pot seedlings is the growth of seedling roots. In the case of pot seedlings, roots that reach the inner peripheral surface of the container continue to extend along the inner peripheral surface, thereby causing root winding. There is a risk that the root roll will squeeze your root with your root, and in the worst case, it may lead to root rot and death. On the other hand, in the case of a container seedling, a plurality of air root cutting holes are radially formed along the inner circumferential surface of the cavity. Therefore, the roots extend along the lower side so as to avoid the air root hole, and the growth is stopped by the air root hole at the bottom. Thereby, a root winding does not arise in a container seedling.

  In addition to the seedling raising device, a cultivation tray constituted by an implantation unit in which a plurality of implantation recesses (cavities) are provided in a row and a frame body that holds the implantation units in a single plane is also known. (For example, see Patent Document 2).

Utility model registration No. 3305361 JP 2008-11729 A

  In the seedling raising apparatus described in Patent Documents 1 and 2, “thinning” or “replanting” is required for cavities that do not germinate after sowing or have seedlings that are poorly grown.

  However, since the container (cavity) is integrally molded with the tray, there is a problem that when there is a seedling that is not properly grown, the container cannot be removed from the tray.

  Further, at the time of shipment, the seedlings are taken out from the container with a dedicated eject machine. All extraction means that all seedlings in the cavity are extracted from the container regardless of the degree of growth. As a result, immature seedlings are returned to the container again, but there is a problem that the subsequent growth becomes unstable due to stress at the time of extraction.

  Further, since the container is integrally molded with the tray, when the tray is placed on rough terrain, there is a possibility that the bottom of the container may cause poor grounding that does not correspond to the uneven terrain on the rough terrain. The poor ground contact at the bottom of the container may cause root rot since the water irrigated to the seedling is not drained from the container.

  Therefore, the present invention has been made in view of the above-described problems of the prior art, and the purpose thereof is to grow a large amount of seedlings having healthy root pots without abnormal root deformation such as root winding. It is to provide a cassette type seedling growing container.

  The cassette type seedling growing container according to the present invention for achieving the above object has a container (10) for growing a seedling, a plurality of the containers (10) and a plurality of legs (26). A seedling growing container having a tray portion (20), wherein the container (10) is formed in a frame portion (11) with an upper portion projecting radially outward, and a lower portion from the upper portion forms a cone-shaped portion (12). The tray portion (20) has a recess (21) into which the frame portion (11) is fitted, and the recess (21) has a through hole (22a) through which the cone-shaped portion (12) passes. Each container (10) is configured to be separable from the tray (20) independently.

  In the above configuration, the container (10) is separable from the tray section (20) and can be displaced in the height direction. As a result, “replanting” and “thinning” can be performed only by exchanging the corresponding container, and all seedlings are not extracted from the container.

  Moreover, the upper part of a container (10) is formed in a frame part (11), and since the upper part is widened, the quantity of the root in the upper part of a root pot can be increased. Thereby, the seedling transplanted to soil comes to grow stably. Furthermore, since the site | part in which a tray part (20) accommodates a container (10) is formed in the recessed part (21), a container (10) becomes non-rotatable. Thereby, especially the attitude | position of the container (10) at the time of moving a container comes to become stable.

  The second feature of the cassette-type seedling growing container according to the present invention is that the top plate (11a) of the frame portion (11) is formed with a collar portion (11d) extending outward in the horizontal direction.

  In the said structure, it becomes easy to take out a container (10) from a tray part (20) with a collar part (11d).

  A third feature of the cassette-type seedling growing container according to the present invention is that the bottom inner peripheral surface (11c) of the frame portion (11) forms a tapered surface whose height increases toward the center. .

  In the above configuration, it is possible to provide water retention to the upper part of the container (10). Thereby, the amount of roots in the frame (11) can be increased.

  A fourth feature of the cassette-type seedling growing container according to the present invention is that the cone-shaped portion (12) has a first slit portion formed at different angles without overlapping radially with respect to the center (12f) of the bottom surface ( 12c) and the second slit portion (12d) are separately provided so as not to overlap in the height direction.

  In the above configuration, the roots of the seedlings are grown so as to extend downward, and the water irrigated to the seedlings can be guided downward and drained through the grounding surface.

  A fifth feature of the cassette-type seedling growing container according to the present invention is that the second slit portion (12d) is formed below the first slit portion (12c), and the number of slits is the first slit portion. More than (12c).

  In the above configuration, the second slit portion (12) guides the root extending downward to the bottom portion. As a result, the irrigated water is suitably guided downward.

  A sixth feature of the cassette-type seedling growing container according to the present invention is that the second slit portion (12d) is formed by cutting out the side surface (12a) and the bottom surface (12b) of the cone-shaped portion (12). The center (12f) is included.

  In the above configuration, the irrigated water is drained through the ground surface by the slit of the bottom surface (12b). Thereby, root rot is suitably prevented.

  A seventh feature of the cassette-type seedling growing container according to the present invention is that a rib (12g) is formed on the inner peripheral surface of the cone-shaped portion (12) with the first slit portion (12c) and the second slit portion ( 12d) so as not to exist on any virtual extension line.

  In the said structure, it grows so that the root of a seedling may extend below by a rib (12g).

  An eighth feature of the cassette-type seedling growing container according to the present invention is that the container (10) is formed of a synthetic resin having transparency.

  In the above configuration, the growth of the seedling can be visualized.

  A ninth feature of the cassette-type seedling growing container according to the present invention is that the tray portion (20) is formed of a synthetic resin having transparency.

  In the said structure, the growth of a seedling can be visualized more clearly.

  A tenth feature of the cassette-type seedling growing container according to the present invention is that the container (10) is formed from a biodegradable material.

  In the said structure, it becomes possible to plant directly with a container (10), without taking out a seedling from a container (10). Moreover, since the biodegradable material can contain an odorous component, it is possible to avoid damage to harmful animals after transplanting.

  An eleventh feature of the cassette-type seedling growing container according to the present invention is that the frame portion is formed in a square frame portion (11) or a cylindrical frame portion.

  In the above configuration, even when the seedling root grows and presses the frame portion, the load is evenly distributed, and thus the deformation of the container (10) can be suitably prevented.

  According to the cassette type seedling growing container of the present invention, the container (10) for growing the seedling is configured to be separately separable from the tray portion (20) and relatively displaceable along the height direction. With regard to seedlings with poor growth, the container can be taken out together, making it easy to manage the growth of seedlings, suitably following uneven terrain on uneven terrain, and suitably preventing root rot due to poor ground contact It becomes possible. In addition, the upper part of the root pot has a large root amount, and the container (10) is shaped so that the roots of the seedlings extend along the lower side, so it has a healthy root pot without abnormal root deformation such as root winding. It is possible to grow a large amount of seedlings.

It is explanatory drawing which shows the cassette type seedling growing container which concerns on one Embodiment of this invention. It is explanatory drawing which shows the cell which concerns on this invention. It is the B section enlarged view of Drawing 2 (d). It is a perspective view showing a tray portion according to the present invention. It is explanatory drawing which shows the uneven | corrugated topography followability of the rough terrain of the cassette type seedling growing container which concerns on one Embodiment of this invention. It is a bottom view of the cell which concerns on other embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is an explanatory view showing a cassette-type seedling growing container 100 according to an embodiment of the present invention.

  The cassette-type seedling growing container 100 includes a plurality of cells 10 that are filled with seedlings and a medium, and a tray unit 20 that accommodates the cells 10. The cassette-type seedling growing container 100 can accommodate a plurality of cells 10 for growing seedlings (40 in this embodiment), and each cell 10 and the tray portion 20 are separable and in the height direction. It is comprised so that relative displacement is possible along. Therefore, “replanting” and “thinning” can be performed by exchanging only the cells 10 having poorly grown seedlings or ungerminated seeds. Here, the “cassette type” means that each cell 10 is not integrated (fixed) to the tray unit 20, and each cell 10 can be taken out from the tray unit 20 and attached to the tray unit 20 freely. Means that it is configured to be done. Hereinafter, each configuration will be further described.

  FIG. 2 is an explanatory diagram showing the cell 10 according to the present invention. 2 (a) is a plan view of the cell 10, FIG. 2 (b) is a front view of the cell 10, FIG. 2 (c) is a bottom view of the cell 10, and FIG. It is AA sectional drawing of (b).

  As shown in FIG. 2A and FIG. 2B, the cell 10 has an upper portion formed in a hollow rectangular column-shaped square frame portion 11 and a lower portion formed in a hollow cone-shaped cone portion 12. The square frame portion 11 includes a top plate 11a, a side plate 11b, and a bottom plate 11c. The top plate 11a has a corner (corner portion) that protrudes outward in the horizontal direction from the corner of the side plate 11b. Thereby, the collar part 11d extended in the horizontal direction outer side is formed in the corner | angular part of the top plate 11a. Thereby, it becomes easy to take out the cell 10 from the tray part 20 by picking the collar part 11d.

  The side plate 11b includes four straight portions and a corner portion that smoothly connects the four straight portions. In addition, the length of the straight part of the side plate 11b and the length of the straight part of the top plate 11a are the same. Further, the bottom plate 11c continuous to the side plate 11b forms a tapered surface whose thickness increases toward the inside in the radial direction. This will be described later with reference to FIG.

  Thus, by forming the upper part of the cell 10 by the square frame part 11, the upper part of the cell 10 becomes wide. In addition, the upper portion of the cell 10 has water retention due to the tapered surface of the bottom plate 11c. As a result, it becomes possible to increase the amount of roots in the upper surface portion of the root pot.

  On the other hand, as shown in FIG. 2B, the cone portion 12 includes a side plate 12a and a bottom plate 12b. Further, as shown in FIG. 2D, the side plate 12a is inclined with respect to the vertical direction so that a gap Δ is formed between the side plates 12a when other cells are stacked. That is, the side plate 12a has a tapered surface.

  Further, as shown in FIG. 2A, four side slits 12c are formed in the side plate 12a at intervals of 90 ° with respect to the center 12f of the bottom plate. Eight second slits 12d are formed at 45 ° intervals with respect to the bottom plate center 12f. The first slit 12c and the second slit 12d are formed so that the second slit 12d is not positioned on the virtual extension line (longitudinal direction) of the first slit 12c.

  The second slit 12d cuts out the side plate 12a and the bottom plate 12b, and further cuts out the bottom plate center 12f. The 1st slit 12c and the 2nd slit 12d are provided so that the root of a seedling may extend below and grow by air pruning (air pruning).

  In addition, the number of the second slits 12d is larger than the number of the first slits 12c. In addition to the air pruning, the second slit 12d guides the water irrigated inside the cell 10 downward, This is because it is provided to drain water.

  Further, as shown in FIGS. 2A and 2D, the side plate 12a is provided with two ribs 12g symmetrically about the bottom plate center 12f. The ribs 12g promote the growth of the roots of the seedlings along the lower side, and suitably suppress the buckling and twisting deformation of the cone part 12. The ribs 12g are formed so that the ribs 12g are not positioned on the virtual extension lines (longitudinal direction) of the first slit 12c and the second slit 12d.

  The cell 10 is preferably molded from a transparent synthetic resin. This makes it possible to visualize the inside of the cell 10 (growth of seedling roots).

  The cell 10 is preferably molded from a biodegradable material. This allows direct planting with the cell 10 without removing the root pot from the cell 10.

  FIG. 3 is an enlarged view of a portion B in FIG. For convenience of explanation, the corner portion and the straight portion of the side plate 11b are shown in an overlapping manner. The inner peripheral surface of the bottom plate 11c of the square frame portion 11 forms a tapered surface whose height increases toward the inside in the radial direction. Thereby, it becomes possible to ensure water retention in the upper part of the cell 10. In addition, the taper surface is ensured long in the corner part.

  FIG. 4 is an explanatory perspective view showing the tray section 20 according to the present invention. The tray portion 20 has recesses 21 having a predetermined depth d for accommodating the cells 10 on the upper surface 24 thereof in a lattice shape (5 vertical × 8 horizontal = 40). In addition, four leg portions 25 that support all the cells 10 are formed at the four corner portions. Note that the number of the leg portions 25 may be four or more, and is not limited to four.

  The inner peripheral surface of the recess 21 includes a bottom surface 22 that receives the cell 10 and a side surface 23 into which the square frame portion 11 of the cell 10 is fitted. A through hole 22 a through which the cone portion 12 of the cell 10 passes is formed in the bottom surface 22. The side surface 23 is formed to be slightly wider than the rectangular frame portion 11 of the cell 10.

FIG. 5 is an explanatory diagram showing the uneven terrain followability of the rough terrain of the cassette-type seedling growing container 100 according to the embodiment of the present invention.
Since each cell 10 and the tray portion 20 that accommodates the cell 10 are configured to be separable, each cell 10 can be displaced in the height direction. Therefore, when the installation surface has uneven terrain, each cell 10 contacts the installation surface by being displaced in the height direction. As a result, it becomes possible to suitably drain the irrigated water through the ground surface.

  As described above, according to the cassette-type seedling growing container 100 according to the present embodiment, the cell 10 and the tray unit 20 that accommodates the cell 10 are separable, and the cell 10 is configured to be relatively displaceable along the height direction. Yes. Thereby, “replanting” and “thinning” for young seedlings or ungerminated seeds can be performed by replacing the cells 10. Since the cells 10 can be taken out individually, it is not necessary to use a dedicated eject machine at the time of shipment. Furthermore, since the cell 10 is configured to be capable of relative displacement along the height direction, the cell 10 can be grounded by following the uneven terrain even when the installation surface has the uneven terrain. Thereby, it becomes possible to drain the irrigated water suitably through the installation surface.

  The top plate 11a corner portion of the square frame portion 11 of the cell 10 is formed in a flange portion 11d protruding outward in the horizontal direction. Thereby, it becomes easy to pick the cell 10 and the replacement of the cell 10 is facilitated.

  Further, the bottom plate 11c of the square frame portion 11 of the cell 10 is formed so as to increase in height toward the inner side in the radial direction. Thereby, the upper part of the cell 10 becomes wide and has water retention. As a result, the amount of seedling roots in the upper part of the root pot increases, and the seedlings grow stably when the seedlings are transplanted into the soil.

  The longitudinal direction of the first slits 12c formed in the side plate 12a of the cone portion 12 radially with respect to the bottom plate center 12f at intervals of 90 ° and the second slits 12d formed at intervals of 45 ° do not coincide with each other. And it is formed so that it may not overlap along the height direction. The second slit 12d includes a bottom plate center 12f by cutting out the side plate 12a and the bottom plate 12b. As a result, the roots of the seedling can be stably extended downward, and the irrigated water can be guided downward and drained suitably through the ground contact surface. As a result, root curling and root rot can be suitably prevented.

  Moreover, when the cell 10 is a transparent synthetic resin molded product, the growth of a seedling can be visualized. When the tray part 20 is a transparent synthetic resin molded product in addition to the cell 10, the growth of the seedling can be visualized more clearly.

  In addition, when the cell 10 is formed from a biodegradable material, the seedling can be transplanted to the soil as it is without taking out the seedling from the cell 10. Since the biodegradable material can contain an odor-eliminating component, it is possible to suitably avoid harmful animal damage after transplantation.

  As mentioned above, although one Embodiment of this invention was described referring drawings, embodiment of this invention is not limited only to the above. That is, various modifications and improvements can be added within the technical scope of the present invention. For example, it is possible to adopt a cylindrical frame portion instead of the square frame portion.

  Further, as shown in FIG. 6, the second slit 12d may be formed so as to reach the bottom plate center 12f with the bottom plate 12b interposed therebetween.
