Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an artificial culture medium for growing plants, and particularly to a plant growing block suitable for growing plant seedlings.

<Conventional Example and Problems> Seedling raising is an important step in growing plants, and during this period, the roots of the plants grow rapidly, and this growth has a great influence on the subsequent growth of the plants.

Therefore, during the seedling raising stage, it is necessary to keep the roots in a particularly good condition.

Plant roots have the property of extending in the direction of gravity and perpendicular to the installation surface of the medium.

Therefore, if there is anything that obstructs the direction of root growth, the growth of the seedlings will be poor and undesirable.

In addition, for growing seedlings, there is a transplant cultivation method in which germinated plants are transplanted before planting and the seedlings are grown. has been done.

Furthermore, sand,
It is known to sow seedlings in vermiculite or the like and transplant the germinated seedlings 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 top surface of the block is split into a groove and the root portion is inserted into the block. If this is done, the restoring and occluding properties of Rockwool at the splitting part will be weak, and the insertion length of the roots of the plant to be planted will be insufficient, making the posture of the supported plant unstable, and the roots will not take root properly. This often results in defects.

<Means for solving the problems> The present invention was proposed in view of the above-mentioned circumstances, and its purpose is to provide a plant growing block suitable for growing plants, especially at the seedling stage. It's about doing.

Another purpose of the present invention is to provide a plant growing block that can stably support plants, promote root attachment, allow efficient plant growing work, and be convenient for transportation and storage. Our goal is to provide the following.

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

The above purpose is to provide a plant growing block formed into a multifaceted three-dimensional structure in which fiber materials can be accumulated and infiltrated with a culture solution. A plant growing block whose material fibers are oriented perpendicular to the installation surface.
This is achieved by

As the material for the plant growing block, in addition to inorganic fibers such as rock wool and glass wool, organic fibers such as cellulose fibers can be used.

Furthermore, it is an embodiment included in the present invention that the shape of the block body is a cube, rectangular parallelepiped, or other polyhedron.

<Example> Hereinafter, the present invention will be explained based on the example shown in the drawings.

Figure 1 shows that blast furnace slag is used as the base material, and several types of ore and coke are mixed with it and melted in a blast furnace.
A block main body 1 for growing plants is shown, which is formed by applying centrifugal force to form rock wool into uniform and fine fibers 1a into a block shape.

The direction of the fibers 1a is perpendicular to the installation surface on which the block body 1 is disposed.

The block main body 1 is formed into a rectangular parallelepiped, and a notch 2 for holding plants is formed extending from one side wall surface to the center.

When using this plant growing block, first widen the notch 2 formed in the block body 1, and insert the root part of the plant to be grown into the edge of this notch 2 located in the center of the block body 1. .

Next, the expanded portion of the cut 2 is closed to clamp and support the plant.

In addition, in order to ensure the support of the plant, the second
As shown in the figure, it is preferable to arrange a band 3 or string made of rubber or flexible synthetic resin on the outer periphery of the side wall of the block body 1 to prevent the cut 2 from expanding.

FIG. 3 shows a plurality of notches 2 in the block body 1.
. . are shown formed at predetermined intervals.

Therefore, when using it, depending on the size and length of the installation place, it can be used as it is, or a plurality of block bodies 1 can be arranged side by side in columns or rows, or if necessary, it can be divided at cuts 2... Use in unit blocks or divided into several blocks.

Alternatively, as shown in FIG. 4, the width may be widened and cuts 2 formed at predetermined intervals on both side walls thereof.

In this case, when dividing into unit blocks, the block body 1 is separated at the positions shown by chain lines.

Incidentally, a notch for splitting may be provided in advance on the chain line 4 in the longitudinal direction of the block body 1 to facilitate splitting.

In forming this plant growing block, the fibers 1a... are arranged horizontally as shown in Figure 5a, and an adhesive (mainly a thermosetting adhesive such as phenolic resin) is sprayed onto the fibers 1a. It is then piled up and heat treated to dry and harden it.

Next, incisions 2 are made in accordance with the direction of the fibers 1a...
..., splitting notches 11 that coincide with the direction of the fibers 1a, and splitting notches 12 that are perpendicular to the direction of the fibers 1a are provided at appropriate intervals (FIG. 5b).

When using the block thus formed, divide it appropriately at the splitting cuts 11...12... and cut the fibers perpendicularly to the installation surface.
Place it in the direction of a...

Since the direction in which the roots extend and the fiber direction of the block are the same, the plants planted in this plant growing block can grow without being inhibited.

This promotes the growth of plant roots and improves their ability to take root on blocks.

In addition, when the culture solution is supplied, the direction of the fibers is in the direction of gravity, which prevents the fibers from being compressed by their own weight, and the density at the top and bottom of the block is approximately the same, so the culture The liquid flows easily, and the necessary amount of culture liquid is maintained between the fibers 1a...
Application of excessive culture solution to plants is prevented, water permeability is improved, and on the other hand, air permeability is ensured, and harmful effects such as root rot of plants due to lack of oxygen can be prevented.

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

The cut 2 is expanded during use, and the cut 2 is closed after the plant is inserted, so that the plant is held and supported within the cut 2 of the block body 1. Therefore, a length suitable for supporting the plant can be inserted into the block main body 1, and the plant supported by this block can be supported in a stable posture.

The nutrient solution supplied to the growing block can be sufficiently absorbed, the block is properly exposed to air, and the fiber direction of the block matches the direction in which the roots grow, resulting in good plant growth and the ability of the roots to Rooting can be promoted.

Furthermore, the structure is such that only the notch 2 is provided in the block body 1, and there is no need to combine other members.
Since it is a one-piece product, there are no protruding parts or the like after molding, so there is no risk of breakage during transportation or handling during storage, and the manufacturing process can be simplified. Furthermore, as shown in Fig. 5, mass production is easily possible and can be provided at low cost by curing the fibers in a plurality of blocks together and providing notches for holding the plant and splitting the fibers. can.

Also, when using the main development block,
Since the work of inserting the plant is completed simply by expanding and closing the cut 2, the transplant work at the stage of raising seedlings and planting becomes extremely easy.
