[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coconut fiber planting material used for hydroponics and the like.

[0002]

2. Description of the Related Art Coconut fruits are made of seeds having an endosperm portion for eating raw or collecting palm oil, and a thick fiber coconut shell surrounding the seeds. The coconut shell from which the seeds have been removed is immersed in water for about one month to decompose,
After drying, the fiber bundle is stripped from a thick fiber layer called mesocarp. This fiber bundle is used as a material for ropes, scourers, etc., but the dust (coconut dust) generated in large quantities during stripping has no use. I was back. Therefore, the present inventor has collected such valueless dust, separated and removed fiber pieces from it, and
It has been developed that it can be used as a planting material by compression molding to about 1/7 volume with a press (Japanese Patent No. 2652834).
issue).

[0003] When water is contained in this planting material, it expands to 7 or 8 times its volume and returns to the original powdery coconut fiber, and is an artificial soil made of a natural material excellent in air permeability and water retention. Can be easily obtained. Usually, a bucket or other container is filled with water, the planting material is immersed in the container, and when the fibers return to a separate state, they are transferred to a planter or a flower pot for use. It was troublesome. Also, if this implant is placed directly on the ground and water is injected, it absorbs water and the implant loses its shape.
The planted seedlings have fallen, and in the case of open fields, there have been problems such as drying and coconut shell fibers being scattered by the wind.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of an implant according to the present invention, and FIG.
Is a central sectional view thereof. Reference numeral 1 denotes an implant according to the present invention. Reference numeral 2 denotes a fiber block, which is manufactured through the following steps. This manufacturing process is based on the method of manufacturing solid implantable material (Patent No.
2652834). First, the coconut hulls after the seeds are collected from the coconut are spoiled in water for about one to two months, and then dried in the sun. The mesocarp is scraped from the dried coconut shell and the remainder is separated into fiber bundles and coconut dust. The component of this coconut dust is mainly powder, but also contains many fine fiber pieces. Then, the dust is dried on the sun, dried and sterilized, and then sieved to remove fiber fragments from the dust to obtain a powder component. A fertilizer may be added to the obtained powder as needed. Next, when the powder or the mixture of the powder and the fertilizer is compressed to about 1/7 by a press, the fiber block 2 is obtained. The shape of the fiber block 2 is not limited to a rectangular parallelepiped, but may be a disk shape. Also, if the compression ratio is too large,
Since the coconut dust fibers are broken by the press and the restoring force is reduced, the compression ratio is suppressed to a value not exceeding 1/8. The lower limit of the compression ratio is not particularly limited, and may be 1 / 1.5 as long as the powder is solidified.

Next, the fiber block 2 is immersed in a natural rubber latex solution for 30 seconds to 5 minutes. The immersion time is adjusted according to the size of the fiber block 2. After immersion, drying and forming the rubber coating 3, if the rubber coating 3 is immersed again in a natural rubber latex solution, the rubber coating 3 can be formed repeatedly, and by repeating this, a desired film thickness can be formed. Such a method for producing the rubber coating 3 is known as a method for producing a rubber dipped product such as a rubber glove. After the immersion step, the coconut shell fiber powder 10 is sprinkled on the natural rubber latex of the fiber block 2 and attached. In this state, when dried in a drying room for 1 to 3 hours, the rubber latex solidifies, a rubber coating 3 made of natural rubber is formed on the outside of the fiber block 2, and a thin coconut shell fiber powder is formed on the surface thereof. Layer 10 is formed. The drying time is adjusted according to the size of the fiber block 2 and the thickness of the rubber coating 3. In this way, if the surface is covered with the protective layer 10 made of coconut shell fiber powder, the natural rubber latex may adhere to other parts and peel off before drying and hardening. Can be prevented. Further, even after the product is completed, the protective layer 10 on the surface can protect the thin rubber coating 3 and prevent the damage. Next, as shown in FIG. 2, holes are made in the rubber coating 3, and planting holes 4 and drainage holes 5 are formed in the center of the upper surface and the bottom surface of the implant 1, respectively. The positions of the planting holes 4 and the drainage holes 5 do not necessarily need to be vertically opposed positions. For example, drain hole 5
May be opened at several positions away from the center of the bottom surface.
Generally, it is preferable that the drainage hole 5 is larger than the opening area of the planting hole 4. The planting hole 4 and the drainage hole 5 are sealed with a moisture-proof, paper-made seal 6 and then the planting material 1.
Is packaged with a heat-shrinkable plastic film (not shown).

At the time of use, the plastic film is removed, the upper and lower seals 6 are peeled off, then placed on the ground surface or the planter 7, and water is poured from above. Water enters from the planting hole 4 and the fiber block 2 absorbs water and expands. At the same time, the rubber coating 3 is also stretched, the total volume of the planting material 1 is increased 7 to 8 times, and a seedbed with a uniform density is formed. Excess water is discharged out of the drain hole 5. Note that the implant 1 may be placed in a shallowly watered container, and water may be sucked through the drain hole 5. A seed or a seedling of a plant is planted on the fiber block 2 through the planting hole 4 and is appropriately irrigated to grow. In the case of hydroponics, a solution in which nutrients are dissolved is supplied. Here, since the implant 1 is covered with the rubber coating 3 which has extended its outer periphery,
The shape of the implant 1 is prevented from being deformed, and the scattering of the fiber block 2 is suppressed. Further, as shown in FIG. 3, the size of the planting material 1 is set in advance according to the size of the planter 7, and a seedbed having a uniform density can be formed without protruding from the planter 7.

FIG. 4 shows another example of use. A bed 8 is formed by the fiber block 2 generated from the coconut shell, and the planting material 1 is placed thereon, and the planting hole 4 is formed as in the case of FIG.
Pour water or water with fertilizer into it. The water injection causes the fiber block 2 of the implant 1 to swell and expand the rubber coating 3 to form a nursery. The water supplied to the implant 1 flows out of the drain hole 5 to the bed 8, soaking the fiber block 2 of the bed 8. Alternatively, the planting material 1 can be directly buried in the soil of the field, and similarly, water or a water in which a fertilizer is dissolved can be poured into the planting hole 4 to form a nursery on the soil. In the planting hole 4 of the planting material 1, seeds or seedlings of flowers and vegetables to be cultivated are planted, and flowers, vegetables and seedlings are grown by hydroponics. As in the case of placing the implant 1 directly in the planter 7, the outer periphery of the implant 1 is covered with the stretched rubber coating 3 so that the fiber block 2 is not scattered and the seeds and the seedlings can be securely held. it can. When the flowers, vegetables, and seedlings grow and take root, the roots are extended to the fiber block 2 of the bed 8 or the field soil through the drain holes 5, and the flowers, vegetables, and seedlings grow without falling. I do.

FIG. 5 shows an example in which a bed 8 is formed by wrapping the outside of a large fiber block with a rubber coating in the same manner as the implant 1, and the drain hole 4 of the implant 1 is formed on the upper surface of the bed 8.
, A root insertion hole 9 is formed thereon, and a drainage hole 5 is formed at the bottom thereof. In this example, the fiber block 2 inside the bed 8 is covered with the comb coating 3 and does not collapse.

The planting material 1 of the embodiment is composed of a fiber block 2 collected from a coconut shell and a natural rubber coating 3, so that after use, the planting material 1 may be left in the ground as it is, It is not polluted because it is decomposed. The rubber coating 3 is not limited to natural rubber latex. The same effect can be obtained by using a synthetic latex of biodegradable plastic that is easily decomposed by microorganisms in the ground.

[0012]

According to the present invention, since the outer side of the fiber block is covered with the rubber coating, when the fiber block is impregnated with water, the rubber coating expands and the fiber block expands without hindrance.
The rubber coating keeps the shape of the planting material well, and plant seeds and seedlings can be planted directly on the planting material without using a flowerpot or a planter. Planting holes and drainage holes are clear on the rubber coating, so plants only need to be planted in the planting holes, and excess water is discharged out of the drainage holes, so that water accumulates inside the implant material. It does not cause root rot. Because it forms a protective layer adhered powder coconut shell fibers on the surface of the rubber coating, a thin rubber coating is protected by a protective layer, and that scratch resistant. Further, when the rubber coating is made of natural rubber, it is easily decomposed by microorganisms in the ground even if the whole is discarded as it is, and does not damage the environment.
