DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray for plant cultivation that can be used for a plurality of uses, such as cultivating flower seedlings and green seedlings while planting pots for raising seedlings and displaying them at stores.

[0002]

2. Description of the Related Art In the field of cultivation of crops such as strawberries and plants such as flower seedlings and green seedlings, elevated cultivation has been widely used mainly for the purpose of reducing the work load. The cultivation apparatus for this elevated cultivation is, for example, a Japanese Utility Model 6-1649.
As described in Japanese Patent Publication No. 5 (1999) -2005, a configuration is provided in which a holder having, for example, a panel shape and a large number of mounting holes is provided on a frame installed on the ground, and a seedling container is inserted and held in the mounting holes. It was done. Then, the seedlings are vegetated by filling the cultivation soil into the seedling raising container, and water supply and fertilization are periodically performed to grow the seedlings.

[0003] Containers for raising seedlings are widely used not only for upland cultivation but also for holding parent strains and raising seedlings, for example, in the case of collecting runners from parent strains and growing seedlings in alley cultivation. It's being used. For example, as shown in FIG. 3 of the above publication, this seedling raising container has a cylindrical shape having a flange at the upper end and a tapered lower end, and an opening at the bottom. Commonly used.

[0004] In cultivation using such a container for raising seedlings,
In addition to cultivation in units of containers, it is possible to handle seedling raising containers one by one or a plurality at a time, including transport and display at stores. For this reason, in order to improve workability such as transfer, a plurality of seedling raising containers may be arranged in a pallet and mounted or stored in a box-shaped container,
This also makes handling much easier. In particular,
When using a container, the seedling raising container can be held so that it does not fall down during shipping and transfer from the production area, so that the grown plants are not damaged and the store can display it as it is stored in the container. Very convenient.

[0005]

However, containers are convenient for transportation or display at stores, but cannot be applied until cultivation. That is, since the original function of the container is to store and transport or display as many seedling raising containers as possible, the arrangement density of the seedling raising containers is considerably high. For this reason, when a large number of seedling raising containers are placed in a container during cultivation, the interval between the plants becomes short, and the leaves interfere with each other, which affects the growing. That is, there is an appropriate line between plants depending on the kind, variety and tailoring method of the plant. For example, it is preferable that the distance between plants is 7 to 10 cm for flower seedlings and 12 to 15 cm for strawberry seedlings. Unless the plants are separated from each other, uniform growth of all the plants stored in the container cannot be expected.

Further, if the inside of the container is partitioned by a rib-shaped partition wall according to the shape and size of the container for raising seedlings, 1
Stability can be maintained by inserting individual seedling-growing containers into the partitioned sections. Therefore, in all of the processes from shipping to transfer and display at the store, handling can be performed without damaging the plants planted in the seedling raising container.

However, although the container can be used from the transfer to the display as described above, the container cannot be handled without any trouble including the cultivation due to the relationship of the array density described above. That is, containers and pallets have utility after shipment, but are not suitable for cultivation with the seedling containers stored or mounted. Therefore, on the producer side, it is necessary to prepare at least two types of holding tools for cultivation and containers such as containers from shipping to transport or display, and not only the cost problem but also inventory management becomes troublesome. .

As described above, conventionally, although a large number of seedling containers can be shipped, transported, and displayed at stores by using containers, there is a problem that the seedling containers cannot be properly handled including cultivation. .

[0009] It is an object of the present invention to provide a tray for plant cultivation, which can be used conveniently in any of cultivation of a plant using a container for raising seedlings, transfer after shipment, and display at a store.

[0010]

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view showing a plant cultivation tray according to an embodiment of the present invention, together with a seedling raising container.
(A) and (b) are a plan view and a bottom view of the plant cultivation tray of FIG. 1, and FIG. 3 is a longitudinal sectional view taken along line AA of FIG. 1.

As shown in the drawing, a tray 1 for plant cultivation of the present invention comprises a first plate 2
And a second plate 3 that faces upward during transportation after shipment and display at stores.
Each of the first and second plates is made of polystyrene foam for weight reduction, and has a plate thickness of about 6 cm, a rectangular shape having a long side of 50 to 100 cm and a short side of about 30 to 70 cm.

As shown in FIGS. 2A and 2B, the first and second plates 2 and 3 respectively have circular holes 2a and 3b.
a is distributed. The inner diameter of the hole 2a of the first plate 2 is about 4.5 cm, and the hole 3a of the second plate 3
Is slightly smaller than that of the first plate 2 and 3.6
cm. These first and second plates 2 and 3
The size of the inner diameter of each of the holes 2a and 3a corresponds to the size of the seedling raising container 10 shown in FIG.

That is, the container 10 for raising seedlings has substantially the same structure as that shown in FIG. 3 of the above-mentioned Japanese Utility Model Publication No. 6-16495, and has a taper that gradually tapers toward the lower end. The main body 10a has a substantially cylindrical shape having a main body portion 10a and a flange 10b formed at an upper end thereof, and an opening 10c is formed in a bottom surface portion. Therefore, in order to insert and hold the seedling container 10 during cultivation, the first
The hole 2a of the plate 2 is the flange 10 of the container 10 for raising seedlings.
b and slightly larger than the outer diameter of the upper end of the main body 10a. The inner diameter of the hole 3a of the second plate 3 can be fitted to the tapered main body 10a such that the lower end does not protrude from the lower surface of the second plate 3 when the seedling raising container 10 is inserted from above. Degree.

The holes 2a provided in the first plate 2 are formed by arranging 11 rows of combinations of two arrangements in the short side direction at a constant pitch in the long side direction. As can be seen, the arrangement is staggered as a whole. On the other hand, as shown in FIG. 2B, the holes 3a of the second plate 3 are arranged in 11 rows at the same arrangement pitch as the holes 2a of the first plate 2 by combining five arrangements in the short side direction. It is an arrangement. The first and second plates are so arranged that all of the holes 2a of the first plate 2 are substantially coaxially aligned with one of the holes 3a of the second plate 3 so as to be integrated through holes. The two and three are superposed and integrated.

FIG. 3 is a longitudinal sectional view showing the relationship between the holes 2a and 3a, and the holes 2a-1 and 2a in FIG.
2a-2 are holes 3a-1, 3a-2 in FIG.
Consistent with. The holes 2a-3 and 2a-4 in the rows adjacent to the holes 2a-1 and 2a-2 are respectively provided in the second plate 2
Holes 3a-3, 3a-4. And
The same applies to the formation patterns of the holes 2a, 3a arranged from the right side of the holes 2a-3, 2a-4, 3a-3, 3a-4. Therefore, according to the arrangement of the holes 2a and 3a of the first and second plates 2 and 3, all the holes 2a are connected to the holes 3a that are aligned with the holes 2a and 3a.
3 penetrates. Of the five rows of holes 3a arranged in one row, only two of them are aligned with the holes 2a of the first plate 2, but the remaining three are closed by the first plate 2.

Further, the first plate 2 has a structure shown in FIG.
A small-diameter drain hole 2b is provided as the pattern shown. These drains 2b are formed in portions where the holes 3a of the second plate 3 do not align with the holes 2a of the first plate 2, that is, portions closed by the first plate 2, as shown in FIG. is there. As is clear from FIG. 3, each of the holes 3a of the second plate 3 has an array pattern including two drain holes 2b.

The first and second plates 2 and 3 may be integrated by superimposing them and bonding them with an appropriate adhesive.

In the above arrangement, when raising seedlings and the like in the seedling raising container 10, the plant cultivation tray 1 is used.
Is installed in a frame (not shown) of the elevated cultivation apparatus or the like as the posture of FIGS. Then, as shown in FIG. 4, the seedling raising container 10 is inserted through the hole 2 a of the first plate 2. At this time, since all the holes 2 a of the first plate 2 are connected to the holes 3 a of the second plate 3, the seedling raising container 10 is inserted up to the hole 3 a of the second plate 3.

That is, the main body 10b of the container 10 for raising seedlings
Is tapered toward the lower end. For this reason, the inner diameter of the hole 2a of the first plate 2 is made slightly larger than the outer diameter of the main body 10b directly below the flange 10b, and the hole 3a of the second plate 3 is positioned in the height direction of the main body 10a. If it is made slightly larger than the outer diameter of the substantially intermediate portion, the entire main body 10a is dropped into the holes 2a, 3a. Therefore, the seedling raising container 10 has its flange 10b.
Is seated on the surface of the first plate 2 and held.

As described above, the seedling raising container 10 is incorporated so as to penetrate the holes 2a and 3a which are integrally connected, and the arrangement is such that the flange 10b is arranged along the first plate 2 for all the seedling raising containers 10. can do. For this reason, when water or liquid fertilizer is poured onto the first plate 2 during cultivation, the water or liquid fertilizer easily flows into the main body 10a, and conditions for water supply and fertilization to all the seedling raising containers 10 are provided. Can be made uniform. As shown in FIG. 2A, the arrangement pattern of the holes 2a provided in the first plate 2 is distributed in the longitudinal direction of the first plate 2 in a staggered set of two arrangements. The interval between 2a is wide, and a suitable plant can be provided for the plant to be cultivated. Therefore, the seedling raising container 1 inserted into these holes 2a
Interference between the leaves of the plants growing from the cultivation of zero is suppressed, and the plants can be grown healthy in each of the seedling raising containers 10.

The length of the main body 10a of the seedling raising container 10 need not be equal to the total thickness of the first and second plates 2 and 3, but may be shorter or longer. Main body 10a
Is long, as shown by a two-dot chain line in FIG.
Only its lower end protrudes downward from the bottom surface of the second plate 3. And, in the case of the elevated cultivation, since the first and second plates 2 and 3 are installed at a height floating above the ground,
There is no problem even if the main body 10a protrudes downward from the second plate 3. As described above, when the holes 2a of the first plate 2 are used during cultivation, the seedling raising container 10 is used.
There is no restriction on the length, but the relationship between the outer diameter of the main body 10a directly below the flange 10b and the inner diameter of the hole 2a, and the outer diameter of the intermediate height portion of the main body 10b and the second plate It goes without saying that the relationship with the hole 3a needs to satisfy the above-mentioned conditions.

On the other hand, when the grown seedlings are shipped, transported and displayed at the storefront, the seedling raising container 10 is pulled out from the first and second plates 2 and 3 and plant cultivation is performed from the state shown in FIGS. Tray 1 is turned upside down. Thereby, as shown in FIG. 5, the second plate 3 is arranged on the upper side, and the holes 3a of the arrangement pattern shown in FIG.
Faces up. As shown in FIG. 3, only two holes 3a of a set of five arrays are connected to the holes 2a of the first plate 2, and the remaining three holes 3a are drained by two. It continues to the hole 2b. Therefore, the seedling raising container 10 inserted into the hole 3a arranged on the left side in FIG. 5 is inserted until the lower end of the container 10 comes into contact with the first plate 2. At this insertion length, as long as the outer diameter of the main body 10a corresponding to the upper end portion of the hole 3a is set to the extent that the outer diameter of the main body 10a fits into the hole 3a exactly, the inner peripheral surface of the main body 10a is formed. And the seedling raising container 10 is prevented from coming off. Further, the seedling raising container 10 inserted into the hole 3a arranged on the right side in FIG. 5 is held so as to be substantially the same height as the seedling raising container 10 arranged on the left side. That is, although the hole 3a arranged on the right side is continuous with the hole 2a of the first plate 2, the container 10 for raising the seedling is placed on the left side by fitting based on the relationship between the inner diameter of the hole 3a and the outer diameter of the container 10 for raising the seedling. It can be inserted to be the same height as the arrangement.

Therefore, from the time of shipment, the seedling raising container 10 can be inserted into all the holes 3a up to the middle height of the main body 10a as shown in FIG. At this time, since the number of holes 3a of the second plate 3 is larger than the number of holes 2a of the first plate 2 used during cultivation, a large number of seedling raising containers 10 can be transported or displayed at stores. Therefore, the efficiency of transportation work and the display of a large number of plants in stores can be achieved, and the functions can be expanded as well as for cultivation. At the time of this exhibition, the holes 3a are connected to the holes 2a or the drain holes 2b.
Even if water is supplied by inserting the seedling container 10 into the
a and water can be drained from the drain hole 2b. Also,
The seedling raising container 10 has a flange 1 as shown in FIGS.
Since 0b is raised from the surface of the second plate 3, it is only necessary to grasp the flange 10b by hand when removing it, and it is easy to observe the product by holding it at the store.

If the inside diameter of the hole 3a of the second plate 3 connected to the hole 2a in FIG. 5 is slightly increased, the flange 10b of the container 10 for seedling raising sits on the surface of the second plate 3. Can be inserted up to For this reason, in the set of five arrangements, the seedling raising container 10 inserted in the two holes 3a connected to the hole 2a is lowered, and the other seedling raising containers 10 are lowered in the left arrangement shown in FIG. As a result, a step can be provided. Therefore, for example, a thing with a large growth height of the spot can be handled by inserting it into the hole 3a connected to the hole 2a of the first plate 2 to suppress the height. For this reason, the plants to be displayed can be arranged neatly, and a display with a good appearance can be obtained.

FIG. 7 is a longitudinal sectional view of a main part in which water can be easily collected in the seedling raising container 10 during cultivation so that more suitable breeding can be performed.

In FIG. 7, on the surface of the first panel 2 and around the hole 2a, a mortar-shaped recess 2b and a flange 10b of the seedling-growing container 10 formed at the lowest portion of the recess 2b can be dropped. A step 2c having a size is provided. The planar shape of the concave portion 2b may be a circle or a square, but the step portion 2c is a circular shape into which the flange 10b fits exactly, and the depth thereof is equal to the thickness of the flange 10b.

When such a concave portion 2b and a stepped portion 2c are provided in the first plate 2, the flange 10
b has been lowered to the bottom of the recess 2b,
The water sprinkled on the surface of the plate 2 accumulates in the recess 2b and easily flows into the seedling raising container 10. Therefore, the function of collecting water to the seedling raising container 10 is improved as compared with the case of the example of FIG. 4, water can be used without waste, and cultivation and cultivation can be effectively promoted.

[0033]

According to the present invention, the number of seedling containers to be arranged can be set appropriately for cultivation using the seedling containers and for shipping and transportation after growth and for display at the store. Each seedling container promotes rapid growth of the plant, and can be efficiently handled by a large number of seedling containers during transportation and display, thereby improving workability.

Further, since one plant cultivation tray can be used for cultivation, transportation and display, the producer can provide a plant cultivation tray as display equipment required by the consumer, and Added value can be increased.
