Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seedling bed for growing pine-shaped seedlings that is placed on a seedling stand of a rice transplanter and a method for manufacturing the same.

When the above-mentioned pine-shaped seedlings are used, they are taken out from the seedling stand in predetermined blocks using planting claws, and conventionally, the seeds are generally sown vertically and horizontally at predetermined intervals when raising the seedlings. However, as the seedlings grow, the roots of adjacent seedlings become tightly intertwined, resulting in a drawback that the size of the block seedlings that are removed varies considerably. Therefore, grooves are formed in the bottom of the soil in a grid pattern so that a predetermined amount of block seedlings can be taken out. Disadvantages that may cause deformation or failure to remove blocked seedlings when placed on the seedling stand, such as compression in the width direction of the seedling stand due to lateral movement of the seedling stand, resulting in missing plants. It was hot.

In view of the above points, it is an object of the present invention to provide a bed for raising pine-shaped seedlings, which can avoid deformation and compression when placed on a seedling stand, and allows for the removal of block seedlings in predetermined amounts at a time. purpose.

The nursery bed for pine-shaped seedlings for a rice transplanter according to the present invention includes:
A bedding material for growing seedlings that is filled in a shape-retaining frame material, comprising a first bedding material scattered at predetermined intervals in the vertical and horizontal directions on the bottom plate of the shape-retaining frame material; In combination with a second bedding material that is filled in a continuous layer to fill in the gaps other than the existing locations, the first bedding material has a flat plate shape having a predetermined area. The second bed material is made of a material that is capable of holding the seedlings and has a shape-retaining property that is difficult to disintegrate due to the action of dividing and taking out the seedlings with the planting claws of the rice transplanter. It is characterized in that the flooring material is made of a different material that has greater separability than the first flooring material so that it can be easily separated when taking out the parts.

In other words, the space between the blocks of first bed materials is filled with a second bed material that is easy to separate, and pine-shaped seedlings are grown by sowing into the seeding section provided in the first bed material. That's what I do.

Therefore, when placed on a seedling stand,
Both in the width direction and in the longitudinal direction perpendicular to the width direction, there is no buckling deformation or compression unlike the case where the grooves are provided, and moreover, when taking out the block seedlings with the planting claw, the first The first bedding material can be easily and satisfactorily separated from each other in the second bedding material portion that extends almost all around the bedding material, and it has become possible to take out block seedlings in predetermined amounts at a time.

Next, the second invention resides in that the seedling bed is obtained by a simple manufacturing method.

In order to achieve the above object, the method for manufacturing a seedling bed of the present invention allows seedlings to take root, and has shape retention to the extent that it is difficult to collapse due to the action of dividing and taking out seedlings with the planting claw of a rice transplanter. The column-shaped first flooring material is placed inside the shape-retaining frame material,
This is a method in which they are scattered at predetermined intervals in the vertical and horizontal directions, and then a second flooring material having a higher separability than the first flooring material is filled in the spaces between the areas where the first flooring material is present.

According to the above method, it is sufficient to scatter the first flooring material within the shape-retaining frame material and fill the second flooring material around it. As shown in FIG. 2. Using a mold member 6 equipped with a cylindrical hole 5 for filling and an extruder 7 for it, all of the first flooring materials to be dotted vertically and horizontally are dotted within the shape-retaining frame material at once. It is possible,
As mentioned above, the seedling bed can be produced more quickly and easily than in the case where holes are made in the second bed material that is completely filled in the shape-retaining frame material and the holes are filled with the first bed material. .

In other words, the shape-retaining frame material is filled with the second flooring material, holes for filling the first flooring material are bored in the second flooring material vertically and horizontally, and the holes are filled with the first flooring material. In this case, if the vertical and horizontal holes formed in the second flooring material and the holes in the mold member are slightly misaligned, the first flooring material is filled into the holes formed in the second flooring material using the molding member. Therefore, it is difficult to fill the vertical and horizontal holes formed in the second flooring material with the first flooring material one by one or in small groups. When filling the second flooring material around the first flooring materials, it is possible to dot all the first flooring materials in the retaining frame material at once using a mold member. By eliminating the need for the process of drilling holes for filling the first bedding material in two bedding materials, and by using a mold member to allow the first bedding material to be dotted within the shape-retaining frame material at once, it is possible to create a nursery bed. can be produced quickly and easily.

Hereinafter, embodiments of the present invention will be described in detail based on illustrative drawings.

A seedling raising box 1 serving as a shape-retaining frame material is spaced apart vertically and horizontally at predetermined intervals to allow seedlings to take root, and to retain their shape to the extent that they are difficult to collapse due to the action of dividing and taking out the seedlings with the planting claw of a rice transplanter. The clay first bedding material 2, which is a bedding material with natural properties, is scattered, and the spaces between the first bedding materials 2 are filled in. A sandy second bedding material 3, which is a bedding material with greater separability than the first bedding material 2, is filled, and a recessed portion for accommodating the paddy is attached to the upper part of each of the first bedding materials 2. It is equipped with a seeding section 4 and constitutes a nursery bed for pine-shaped seedlings for use in a rice transplanter.

Next, a method for obtaining the above-mentioned growing seedbed will be explained. As shown in FIG. 2, a clay-like material is filled into each of the cylindrical holes 5 of the mold member 6 using a mold member 6 having cylindrical holes 5 and an extruder 7 for the mold member 6 (FIG. 2). ), then placed in the corresponding position in the seedling raising box 1 and extruded from the mold member 6 by the extruder 7,
The seedlings are placed on the seedling raising box 1 in a scattered manner vertically and horizontally (see B in Figure 2). A protrusion 9 is connected to the pressing end surface of each convex member 8 of the extruder 7, and as the extruder 7 is extruded, the protrusion 9 forms the seeding portion 4. Thereafter, a sand-like material is supplied to fill the gaps between the first flooring materials 2 (see C in FIG. 2).

FIG. 3 shows another embodiment, in which, for example, the first flooring materials 2 are interspersed with each other by a thin bottom plate 2a, which is made by press-molding a material made of paper scraps or the like mixed with an adhesive. At the same time, a sandy second bedding material 3 is filled to fill the gaps between adjacent first bedding materials 2 to form a seedling bed. Further, a shape-retaining frame portion 2b is integrally extended around the outer periphery of the bottom plate 2a. In this other embodiment, the material of the first floor material 2 is a fibrous material, a phenolic resin material, etc., which can be cut at the bottom plate 2a when the seedlings are taken out using the planting claws.
In addition, various materials can be used as long as they are not decomposed by watering during seedling raising, but are decomposed by being immersed in water for a predetermined period of time, and as the material for the second flooring material 3, Various materials can be used as long as they have greater separability than the first floor material 2.

The seedling raising box 1 and the one consisting of the bottom plate 2a and the shape-retaining frame part 2b in another embodiment are collectively referred to as a shape-retaining frame material.
