Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a support block for plants at the stage of raising seedlings, particularly a block for raising seedlings suitable for hydroponic cultivation.

<Prior Art> As a conventional seedling raising device, one is known in which seedlings are sown in sand, vermiculite, etc., and the germinated seedlings are transplanted to rock wool blocks. However, since this type of rock wool block has not been subjected to any processing, when transplanting, a part of the surface of the block is split into grooves and the root portion is inserted into the block. If this is done, the restoring and occluding properties of rock wool at the split portion are weak, so the posture of the supported plant becomes unstable, and roots often fail to take root.

<Purpose> The present invention was provided in order to eliminate the above-mentioned conventional drawbacks, and the purpose is to provide a seedling-raising block that can stably support plants and promote root establishment. The aim is to provide the following.

The purpose of this invention is to provide a seedling growing block that is convenient for transportation and storage.

Still another object of the present invention is to provide a seedling-raising block that can efficiently carry out seedling-raising work.

Still another object of the present invention is to provide a seedling growing block that is easy to mold and inexpensive to manufacture.

<Structure> The above object of the present invention is to ``in a polyhedral seedling-raising block, by cutting a non-penetrating die slit from one side of the main body of the block toward the other side, the inside surrounded by the slit can be cut. This is achieved by a seedling-raising block characterized in that a cylindrical child piece is formed on one side, and the inner end is integrally connected to the main body with a thickness such that it can be easily separated. Ru.

As the material for the seedling-raising block, in addition to inorganic fibers such as rock wool and glass wool, organic fibers such as cellulose fibers, and synthetic resin foams such as urethane foam can be used.

Further, it is an embodiment included in the present invention that the shape of the block main body is a cube, rectangular parallelepiped, or other surface, and the shape of the child piece is cylindrical, square prism, or other shape.

<Example> Next, the present invention will be described in more detail according to an example shown in the drawings.

Figure 1 shows seedlings made of rock wool made from blast furnace slag as a base material, mixed with several types of ore and coke, melted in a blast furnace, and made into uniform, fine fibers by applying centrifugal force. A block body 1 for use is shown.

In this embodiment, the block body 1 is formed into a rectangular parallelepiped, and a punching die slit 15 is cut from one surface 1a of the two opposing surfaces toward the other surface 1b using a cylindrical punch or the like. . Thus, the cutting die slit 15 does not penetrate through the other surface 1b, but its inner end is cut with a slight distance d from the other surface 1b. A substantially cylindrical child piece 2 is formed inwardly surrounded by the slit 15, and its inner end is integrally connected to the block body 1 while being close to the other surface 1b.

Due to the existence of the above-mentioned separation width d, even if a tool such as a punch is pulled out after cutting the slit, the child piece 2 will not come out together with the tool, and the molding will be completed while it is completely housed within the main body block 1. It is something.

Thus, the above-mentioned block main body 1 and child piece part 2 constitute the seedling raising block of the present invention, and before use, the child piece part 2 is stored and held in connection with the molding block 1 at the inner end. becomes.

Next, how to use the seedling raising block of the present invention will be explained.

First, move the stored child piece 2 to the arrow p in Figure 2.
When pressed or hammered from the direction, the connecting part between the child piece part 2 and the main body 1 is easily broken along the inner edge of the slit 15, and the child piece part 2 is separated from the main body 1, and the one side 1
a Project outward. This can be completely pulled out from the main body 1 as shown in FIG. 3, or an appropriate length can be exposed. Next, one end surface of the child piece part 2 is split as shown in FIG. 4, and the root part of the plant to be raised is inserted into the split part 21. Next, the child piece 2 into which the plant has been inserted is inserted into the hole 11 of the block body 1.

In this embodiment, the split portion 21 is provided during use, but the split portion 21 may be provided in advance together with the slit forming.

Further, when separating the child piece part 2 from the main body block 1, the child piece part 2 may be pressed from one side 1a direction. In this case, the child piece part 2 is separated from the main body 1 and is pushed out and protrudes toward the other surface 1b. Next, by splitting this protruding end surface, it can be used in the same manner as in the previous embodiment.

FIG. 5 shows an embodiment in which the block body 1 is provided with a plurality of punching die slits 15, 15, . . . and child piece portions 2, 2, .

Therefore, when in use, depending on the width and length of the installation location, it can be used as a unit, or a plurality of units can be arranged in vertical or horizontal rows, or if necessary, dividing grooves 12 can be provided to form unit blocks. For every 1
Alternatively, it can be divided into several parts and used.

<Effects> The present invention configured as described above has the following effects.

Since the child piece part 2 is tightly fitted and inserted into the punch hole 11 of the block body 1 during use, the split part 21 at the tip of the child piece part 2 into which the plant is inserted is completely closed. Therefore, the plant is block body 1
The seedlings are held in close contact with the seedling part 2 that is integrated with the seedling block 1, and are not only supported in a stable posture, but also the nutrient solution supplied to the seedling raising block 1 is sufficiently absorbed, thereby promoting the root establishment of the seedlings. It is something that

Furthermore, since the child piece part 2 is molded in a connected manner within the block body 1, no protrusion or the like is produced after molding. Therefore, there is no risk of breakage during transportation or handling during storage, and the manufacturing process can be simplified.

Furthermore, when using the proposed seedling raising block,
Just by pressing or pressing one end surface of the child piece part 2 housed in the booklet 1, the other end protrudes from the block body 1, so that the work of inserting the plant can be easily performed.
