Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seed fixture used when seeds are germinated and grown on a seedling raising tray.

[0002]

2. Description of the Related Art Conventionally, when seedlings such as vegetables and flowers are germinated to grow seedlings, a tray for raising seedlings made of a synthetic resin is often used. This seedling-raising tray has a configuration in which a large number of grid-shaped recesses called tops are arranged in the vertical and horizontal directions, and those with different sizes of the recesses in advance so that the amount of culture soil can be changed according to the growth of seedlings. Multiple types are available.

When seeds are germinated and grown using the above-mentioned seedling-growing tray, the seeds are usually planted and germinated in substantially the center of the culture soil contained in the recesses. When the seedlings become larger after germination, they are transplanted to a slightly larger seedling-raising tray than the seedling-raising tray used at the time of germination by using an automatic transplanter to grow the seedlings.

[0004]

When a seedling-growing tray is used to germinate seeds, seeds c are planted almost in the center of the recess b of the seedling-raising tray a as shown in FIG. Finally, the seeding force causes the seeds to stretch laterally, and as a result, germination occurs at a position outside the center of the recess b.

For this reason, when seedlings are transplanted to a slightly larger seedling raising tray by using the automatic transplanter, many seedlings that are not captured by the automatic seeder and fall off occur, which hinders the transplanting of seedlings. There were some problems, such as the inability to use an automatic transplanter for transplanting seedlings. The present invention has been made to improve such conventional problems, and provides a seed fixture for fixing seeds so as to germinate in almost the central portion of the recess of the seedling-growing tray, so that transplanting work by an automatic transplanter can be performed. The purpose is to enable smooth and efficient operation.

[0006]

In order to achieve the above-mentioned object, the present invention contains culture soil in a large number of vertically and horizontally arranged recesses, and seeds are planted in the culture soil. In the seedling raising tray that cultivates seeds,
To form a seed fixture main body from a seed fixing part that stores seeds and a rooting part that is connected to the lower part of the seed fixing part, and to embed the seed fixture main body in the culture soil in each recess of the upper part. Thus, the seeds are fixed almost in the center of the recess.

With the above structure, seeds germinate and grow in the center of each recess of the seedling tray, so that seedlings can be reliably captured when transplanted using an automatic transplanter.
This allows the transplant work to be performed smoothly and efficiently.

Further, a slit is formed in the seed fixing portion and a split groove continuous with the slit is formed in the root portion in the longitudinal direction. With the above configuration, when the seed expands, the slit expands, so that germination of the seed does not interfere with rooting, and when the root or seedling grows, the seed fixture body is naturally divided from the split groove. Does not interfere with root growth.

Further, a large number of water holes are formed in the seed fixing portion, and the main body of the seed fixing device is formed of a fibrous material and a water-soluble paste material or degradable resin. The above configuration does not cause water shortage in seeds, and excessive water prevents germination and growth.

[0010]

Embodiments of the present invention will be described in detail with reference to the drawings shown in FIG. 2 is a front view of the seed fixture, FIG. 3 is a side view of the same, FIG. 4 is a plan view of the same, FIG. 5 is a perspective view of a tray for raising seedlings, FIG. 6 is a plan view showing a usage state of the seed fixture, and FIG. FIG.

In these figures, reference numeral 1 denotes a fixture main body, which is formed by molding a material obtained by kneading a water-soluble paste material with a fibrous material such as pulp. As shown in FIGS. 2 to 4, the seed fixture 1 has a cylindrical seed fixing portion 1a having an oval cross section and a taper portion 1b connected to the lower end side of the seed fixing portion 1a. Small tubular root 1
The root portion 1c has an oval shape which is sufficiently smaller than the oval shape of the seed fixing portion 1a.

A large number of minute water holes 1d are formed in the seed fixing portion 1a, and slits 1e are formed on both sides of the seed fixing portion 1a up to the taper portion 1b so that the seed 2 expands. At this time, the slits 1e do not spread and hinder the expansion of the seeds 2.

Further, split grooves 1f are formed on both sides of the taper portion 1b and the rooting portion 1c of the seed fixture main body 1 so as to be continuous with the slits 1e of the seed fixture 1a. When the seed 2 is planted, the split groove 1f connects the front and rear of the tapered portion 1b and the front and rear of the rooting portion 1c, and ruptures due to the germination of the seed 2 and the expansion of the seed 2 accompanying growth, so that the seed fixture main body 1
Is divided into front and back.

On the other hand, the seedling-raising tray 3 shown in FIG. 6 has a structure in which a large number of recesses 3a are arranged in a grid pattern as in the conventional tray, and the volume of the recesses 3a is set in advance so that the recesses 3a can be transplanted as the seedlings grow. Different types are available.

Next, the operation of the seed fixture constructed as described above will be described with reference to FIGS. 6 and 7. In the germination and seedling of the seed 2, first, the culture soil 4 is accommodated in each recess 3a of the seedling raising tray 3 as shown in FIGS. 6 and 7, and then in the seed fixing portion 1a of the seed fixture main body 1. The seeds 2 are accommodated from above, and the seed fixture main body 1 is inserted from above into the culture soil 4 located substantially in the center of the concave portion 3a so that the rooting portion 1c is on the lower side and embedded.

When the seeds 2 are planted in all the concave portions 3a of the seedling raising tray 3 as described above, the seeds 2 are germinated by irrigating them. Even if the seeds 2 are expanded by irrigation, the seed fixing portion 1a Since the slits 1e provided on both sides expand, the expansion of the seed 2 is not hindered, and water is passed through the large number of water holes 1d formed in the seed fixing portion 1a, so that the seed fixing portion 1a There will be no shortage of water or excess water in the seeds 2 housed inside.

The seeds 2 in the seed fixing part 1a are rooted first before germination, but since the rooted roots 2a are guided downward by the rooting part 1c, they should be laterally stretched by foreign matters in the culture soil 4. Since the seed 2 is fixed by the seed fixture main body 1, it does not move in the culture soil 4. As a result, the seed 2 germinates almost in the center of the concave portion 3a and grows into a seedling 2b, and the seed fixing portion 1a and the rooting portion 1c are further expanded from the inside along with the germination growth of the seed 2, and the seed is irrigated. Since the fixture main body 1 itself is weakened, it ruptures from the split groove 1f and the seed fixture main body 1 is divided into front and rear.

On the other hand, when the seedlings 2b grow to some extent and are transplanted to a slightly larger seedling-raising tray 3, an automatic transplanter (not shown) is used. Since the seedlings are grown in the section, the automatic transplanter can reliably capture the seedlings 2b, which allows the seedlings 2b to be transplanted smoothly and efficiently.

[0019]

As described above in detail, according to the present invention, when seeds are germinated and grown using a seedling-raising tray, the seeds can be fixed almost at the center of the seedling-raising tray.
There is no concern that the seeds will shift from the center of the recess due to rooting or germination. As a result, even when the seedlings are to be transplanted to a larger tray for raising seedlings using an automatic transplanter as the seedling grows, the seedlings can be reliably captured by the automatic transplanter, so the transplanting work can be performed smoothly and efficiently. Like

Further, since the number of seedlings that cannot be captured by the automatic transplanter and cannot be transplanted can be greatly reduced, the yield is improved and the seed fixture body has a slit that expands as the seed expands in the seed fixture. Since it has, it does not inhibit the expansion and germination of seeds. Furthermore, as the seedlings are rooted, the seed fixture itself is divided into multiple parts by the split grooves provided in the rooting part, so it does not hinder the growth of seedlings and roots, and the fiber material such as pulp makes it easy. Since it can be molded, it can be provided at low cost.
