Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a seedling raising frame used for growing seedlings of onions, cucumbers, tomatoes, eggplants, squash, green peppers, etc., for example.

[Conventional technology]

When raising seedlings of various vegetables, it is customary to use a seedling-raising container made of a water-permeable and air-permeable material and divided into a large number of chambers, since it is easy to make a seedling bed. This seedling growing container is generally called a paper pot because its material is usually made of paper.

When growing seedlings using such a seedling growing container, if the outer periphery of the seedling growing container is exposed to the atmosphere,
The soil in the container located near the outer periphery of the seedling-growing container tends to dry out, making it difficult to promote normal germination and causing problems in that uniform germination cannot be obtained.

Therefore, conventionally, as disclosed in, for example, Japanese Utility Model Publication No. 48-3334 or Japanese Utility Model Application Publication No. 58-182650, the outer periphery of the seedling-growing container exposed to the atmosphere has been placed in a seedling-growing frame. This seedling-growing frame prevents the soil in the container located near the outer periphery of the seedling-growing container from drying out prematurely, so that germination in the vicinity of the outer periphery of the seedling-growing container and other parts will be uniform and normal. The following is proposed.

[Problem that the invention attempts to solve]

However, in the conventional seedling-raising frame, as shown in FIG. 3, unless the seedling-raising frame 10 is installed in close contact with the outer peripheral surface of the seedling-raising container 11, there is a gap S between the seedling-raising container 11 and the seedling-raising frame 10. will occur. If there is even a slight gap S between the seedling growing container 11 and the seedling growing frame 10, the air will enter through this gap S, and the soil near the outer periphery of the breathable seedling growing container 11 and the soil in other parts will be As a result, the soil near the outer periphery of the seedling growing container 11 that is exposed to the atmosphere dries early, inhibiting normal germination and making uniform germination difficult.

In the conventional seedling-raising frame described above, it is extremely difficult to bring all of the plurality of seedling-raising frames 10 into close contact with the entire outer peripheral surface of the group of seedling-raising containers 11. This is because the seedling raising frame 10 has a relatively long shape, and the seedling raising frame 10 and the seedling raising container 1
1 also has a dimensional error, so even if a part of the seedling-raising frame 10 is brought into close contact with the outer peripheral surface of the group of seedling-raising containers 11, gaps are likely to occur between the two in other parts. be.

Therefore, the soil in the vicinity of the gap dries quickly, creating a difference in dryness and moisture in the soil in the seedling growing container 11, making it difficult to promote uniform normal germination, leading to a decrease in the normal germination rate. There was a problem.

[Means for solving problems]

In the seedling raising frame according to the present invention, a cushioning member is provided on the side of the seedling raising frame that is in contact with each of the seedling raising containers in the seedling raising frame body that holds a plurality of air permeable seedling growing containers so as to be arranged side by side. It is characterized by

Further, it is preferable that the cushioning property adding member is made of a porous soft material.

[Effect]

As mentioned above, if the cushioning member is provided on the side of the seedling raising frame that comes in contact with the seedling raising container, even if the setting position of the seedling raising frame with respect to the seedling raising container is slightly misaligned, or the seedling raising frame or Even if each seedling growing container has slight dimensional errors or deformations, the gap between each seedling growing container and the seedling growing frame will be filled with the cushioning material, and no gap will be created between the two. . Therefore, the soil adjacent to the cushioning member in the breathable seedling growing container is prevented from drying out prematurely due to the air blocking function of the cushioning member.

Therefore, the soil near the outer periphery of the seedling growing container has the same wet soil conditions as the soil in other parts of the container, promoting uniform normal germination and uniform growth.

Furthermore, when the cushioning property adding member is formed of a soft material made of a porous material, the cushioning property adding member has heat retention property and is formed of a porous material. Since this additional cushioning member retains heat and water, the soil in the seedling growing container adjacent to the additional cushioning member is further prevented from drying out prematurely. As a result, the soil near the outer periphery of the seedling-growing container has the same wet soil conditions as the soil in other parts of the container, further promoting uniform normal germination and uniform growth.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in FIG. 1, the seedling growing container 1 is made of a material having water permeability and air permeability, such as paper, and is generally referred to as a paper pot. This seedling-growing container 1 has a planar hexagonal pattern as a whole divided into a large number of chambers, and each chamber has a structure of a through hole opening upward and downward. A large number of the seedling-growing containers 1 are arranged in close rows in the horizontal direction.

The seedling raising frame 2 of the present invention is placed on the outer peripheral surface of the side exposed to the atmosphere in the group of seedling raising containers 1 arranged side by side.
are arranged along the outer peripheral surface of the seedling raising container 1 group and are placed in contact with each other. As a result, the outer periphery of the group of seedling growing containers 1 arranged in parallel is surrounded by a plurality of seedling growing frames 2, so that each of the seedling growing containers 1...
The seedling raising frames 2 hold the seedlings in a juxtaposed state in close contact with each other. These seedling raising frames 2... are made of a material with excellent heat insulation properties, such as expanded polystyrene, and a cushioning member is provided on the side of the seedling raising frames 3 that are in contact with the seedling growing containers 1... It consists of 4...

The seedling raising frame 3 has a long and narrow substantially rectangular parallelepiped shape, and has a sloped surface 3a formed at the upper end corner facing the seedling raising container 1 to ensure sunlight to the seedling raising container 1. It is configured so that it can be done.
The cushioning member 4 usually has a thickness of about 2 to 10 mm, and is preferably made of a soft material. moreover,
The cushioning property adding member 4 is desirably made of a porous material, thereby ensuring water retention. Specifically, it is preferable to use open-cell urethane foam, pulp fiber, or the like as the cushioning member 4.

Further, the seedling raising frame 2 is provided with a fixture 5 for fixing its arrangement position. The position of the seedling-growing frame 2 is fixed by hooking the upper L-shaped part of the fixture 5 to the upper end of the seedling-raising frame 3 and embedding the sharp lower end of the fixture 5 in the ground. It is.

In the above configuration, since the cushioning member 4 is provided on the side of the seedling raising frame 3 that comes into contact with the seedling raising container 1, when setting up the attachment of the seedling raising frame 2, even if the setting of the seedling raising frame 2 with respect to the seedling raising container 1 is Even if there is a slight shift in position, or even if there is a slight dimensional error or deformation in the seedling growing frame 3 of the seedling growing frame 2 or each seedling growing container 1, the relationship between each seedling growing container 1 and the seedling growing frame 2 will be correct. Since the cushioning member 4 absorbs the gap between the two and fills the space, there is no gap between the two.

Therefore, the soil adjacent to the cushioning member 4 in the seedling raising container 1 having air permeability and water permeability is prevented from drying out prematurely due to the air blocking function of the cushioning member 4. Furthermore, the cushioning property adding member 4 has heat retaining properties and also has water retaining properties by forming a porous body with open cells. By retaining water, the soil in the seedling growing container 1 adjacent to the cushioning addition member 4 is further prevented from drying out prematurely, and the soil near the outer periphery of the seedling growing container 1 is
The wet soil conditions are the same as those of the soil in other parts of the same container 1, which promotes uniform normal germination and uniform growth of seedlings.

[Effect of idea]

As described above, in the seedling raising frame according to claim 1 of the present invention, contact with each of the seedling raising containers in the seedling raising frame body that holds a plurality of air permeable seedling raising containers so as to be closely arranged in parallel with each other. It has a structure in which a cushioning property adding member is provided on the surface side.

As a result, even if there is a slight deviation in the setting position of the seedling-raising frame relative to the seedling-raising container, or even if there is a slight dimensional error or deformation of the seedling-raising frame or each seedling-raising container, the distance between the seedling-raising containers and each seedling-raising container will be maintained. The gap is filled with the cushioning property adding member, and no gap is created between the two.

Therefore, in the above structure, the soil adjacent to the cushioning member in the air-permeable seedling growing container is prevented from drying out prematurely due to the air blocking function of the cushioning member.

As a result, with the above structure, the soil near the outer periphery of the seedling-growing container and the soil in other parts of the container have the same moist soil conditions, which allows the seeds to grow uniformly and improve the normal germination rate. It has the effect of contributing to the growth of seedlings and making the growth of seedlings uniform.

As described above, in the seedling raising frame according to claim 2 of the present invention, in the seedling raising frame according to claim 1, the cushioning member is formed of a soft material made of a porous material. It is the composition.

Therefore, in addition to the effect of the invention recited in claim 2, the above structure allows the soil in the seedling growing container adjacent to the cushioning member to dry quickly due to the heat retention property of the cushioning member. is further suppressed.

As a result, with the above configuration, the wet soil conditions between the soil near the outer periphery of the seedling raising container and the soil in other parts of the container become more uniform, and the growth of the seeds is uniform and a normal germination rate is achieved. This has the effect of further contributing to the improvement of seedlings and making the growth of seedlings more uniform.
