[0008]

Problems to be Solved by the Invention The conventional techniques for raising and winding long seedlings (also known as long mat seedlings, long seedling mats, long seedling mats, and roll seedling mats) are as described above.
It is a nursery factory-like facility that uses power, and it is difficult for farmers to introduce. In particular, long hydroponic beds are difficult to maintain horizontal, and in addition to equipment such as pumps, tanks, and heating devices, EC meters, dissolved oxygen meters, pH meters, and self-recording are required for nutrient solution control and cultivation management. Instruments such as temperature and water thermometers are required, making it difficult to introduce and manage even large-scale farmers.
This is a technology for cooperative nursery facilities for many farmers. In addition, greening and hardening of the germinated seedlings require a large-area greenhouse / house.

[0009] Regardless of the mechanical method described above, in order to wind a long seedling manually without using a tool, first, in order to avoid damage by a transplanting nail of a rice transplanter / transplanter, the seedling is reversed in the winding direction. Fold it flat with a roll in the direction and hold it with a large number of iron plates with handles. Carefully apply force only downward on the long seedlings while shifting the holding iron plate one by one horizontally so that the long seedlings do not stretch vertically so that the seedlings do not rise,
There is a method in which a take-up roll such as a hard vinyl chloride pipe is rolled by human power and wound up tightly. However, it is very inefficient and requires skill.

[0010] In order to fully exhibit the characteristics of labor-saving nursery and labor-saving transplantation possessed by long seedlings, it is necessary to develop a simple and easy-to-manage nursery raising method that can be executed by individual farmers and a winding method.

[0011]

Means for Solving the Problems A polystyrene non-woven fabric is heated with a heat roller or the like, and the fibers are bonded to each other, have no elongation, are permeable to water and air, and are not penetrated by seedling roots or buds. , Etc.) is spread on the bottom or top or both sides of the seedling seedling substrate, and these sheets / films are stacked and rolled together with the seed / seedling substrate into a cylindrical shape and put into a seedling incubator. Root.

It is also possible to use a rock-wool sheet, a streaked open-cell urea resin sheet, or the like, as a seedling-growing base material, which can be used as a seedling-growing substrate, using a lightweight material that does not bend during drying (bends when containing water). In this case, it is desirable to lay the above-mentioned sheet film on the bottom surface or both surfaces. When using as a seedling base material a flexible and rollable seedling cultivation substitute molding material, a resin-mixed wood pulp sheet, or a rice hull mat mixed with polyester resin mixed with rice husk and heat-treated as a seedling raising substrate, it is long without cutting. Unfolded and seeded as it is, and place the above-mentioned sheet / film on the surface or bottom,
Or spread on both sides, roll it into a cylindrical shape, put it in a seedling incubator and let it emerge and root.

[0013] Of course, a molten resin such as polyethylene or polyester or paraffin is applied only to the bottom surface of a flexible resin-mixed wood pulp sheet or a rice hull mat, or a biodegradable sheet such as oil paper is adhered to the bottom surface. It is also possible to prevent the sprouts and roots of the sown seed from penetrating into the bottom surface of the seedling raising substrate that is overlaid thereon. In this case,
It is not necessary to lay the above-mentioned sheet and film.
Root penetration prevention treatment Only the seedling raising base material can be wound and put in a seedling incubator similarly to emerge and emerge. However, seedling separation at the time of transplantation,
Problems remain in the decomposition of the seedling raising material in the field.

[0014] Seeds sown at an appropriate temperature in the seedling incubator are rooted,

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments will be described with reference to the drawings.

FIG. 1 shows the state of the present invention at the end of sowing. A polystyrene nonwoven fabric is heated with a heat roller or the like on a long seedling raising plate 1 corresponding to the width of a conventional seedling raising box,
There is no elongation where the fibers are bonded to each other, it penetrates water and air,
A seedling root, a sheet through which shoots do not penetrate, or an underlay 2 such as a polyethylene film is laid. On top of that, the edges of the seedling cultivation soil substitute molding material 3 that is lightweight and does not bend when dry, such as a rock wool sheet or a streaked open-cell urea resin sheet, are arranged side by side. If necessary, thin cotton 4 is laid for preventing root rising and inducing ventilation, etc., watered, and seeds 5 are sown. If necessary, a cover 7 made of the above-mentioned polystyrene non-woven fabric sheet or polyethylene film or the like is placed as an overlay. The edge 6 on the short side of the seedling cultivation substitute molding material 3 that does not bend when dried is shaved diagonally.
Each shaved surface is overlapped and connected. One end of the underlay 2 or the like is allowed to protrude from the seedling cultivation soil substitute forming material 3 or the like with a sufficient margin as shown in the figure.

When the above-mentioned flexible resin-mixed wood pulp sheet or polyester resin-mixed rice hull mat is used as a seedling base material in place of the seedling-growing soil substitute forming material 3 that does not bend when dried, it is not formed but long. Since it is unfolded and sowed as it is, it is not necessary to sharpen the edge of the short side. In this case, the seed 5 is sown while being dried without watering, and the cover 7 is sown.
It is also possible to wind the seedlings into a cylinder and store them as described below, immerse them in water as they are when raising the seedlings, and then raise the seedlings as described below. If the cover 7 is adhered to the seedling raising substrate with a water-soluble adhesive or pressure-sensitive adhesive such as polyvinyl alcohol, trade name Desolvo, etc., the seeds 5 do not spill much during movement.

FIG. 2 shows the emerging cylinder 8, and FIG. 3 shows the emerging and rooted cylinder 8. In FIG. 2, the front surface of the heat-retaining cover of the electrothermal steam raising device A used for raising rice seedlings using the conventional cultivation is rolled up to show the inside. The seedling raising material such as the seedling cultivation soil substitute material 3 described in the previous section is wound from one end with the underlay 2 or the like as a reinforcing material, the aluminum or other square pipe 10 as a core, and the rolled surface is the underlay 2 Is wound around the protruding portion, and the end is stopped with an adhesive tape 9 or the like to form a cylinder 8. In the case where a resin or the like is applied to the bottom surface of the seedling raising base material according to the above paragraph 0013, or a biodegradable sheet such as oil paper is adhered to the bottom surface, etc., after winding, the above-mentioned sheet and film are wrapped and fixed, and the cylinder 8 is fixed. I do. If the above-mentioned cylinders 8 are arranged on each shelf of the electrothermal steam incubator A, a heat insulating cover is hung, electricity is supplied, and steam is heated at about 28 to 32 ° C.,
The seed emerges and emerges in a few days. Of course, even if the above-mentioned cylinder 8 is kept warm in a house, a greenhouse, or a heat-retaining tunnel after late spring without using a seedling raising device, it takes a few days, but budding and rooting are possible.

When the seed 5 germinates or emerges, the layers of the wound seedling substrate are separated and firmly pressed by the cover 7, the underlay 2, the coating resin, the adhesive oil paper, etc. It does not penetrate into the bottom surface of the seedling raising substrate such as the seedling cultivation substitute molding material 3 where the roots overlap, and do not rise. When the shaved surfaces of the short side edges 6 of the seedling cultivation substitute molding material 3 are overlapped and connected, the roots extend through the connection surface, and the respective seedling cultivation soil substitute molding materials 3 are securely connected.

After budding, the cylinder 8 is taken out of the electrothermal steam raising apparatus A, and the edged seedling boards 15 obtained by cutting water-resistant plywood or the like are arranged on a commercially available long scaffold made of steel or aluminum. Roll the cylinder 8 and unfold the long seedlings,
Raise the seedlings in a thermal tunnel. Precautions for greening and hardening, irrigation, heat retention, etc. are the same as the conventional seedling raising method.
When the cylinder 8 is wound up with the cover 7 covered,
Plays the role of a light-shielding sheet / film for greening. The underlay 2 covers the top of the seedling raising board 2 as it is as the underlay for raising the seedlings, and prevents the root from extending downward from the seam of the seedling raising board 1 to prevent the winding work described in the next section from being hindered.

Using the cotton nonwoven fabric or the like used for the hydroponic seedling as a seedling raising substrate, after sowing and watering, the cover 7 of the sheet / film is sprung into a cotton nonwoven fabric or the like overlaid thereon,
Cover as a reinforcing material to prevent root penetration and wrap similarly.
And put into an electrothermal steam raising incubator A for germination and rooting.
Next, the seedling cultivation soil substitute forming material 3, a flexible resin-mixed wood pulp sheet, a polyester resin-mixed rice hull mat, and the like are installed on the rimmed seedling plate 15 arranged on the scaffold plate and the like, and diluted liquid fertilizer and the like. Is irrigated and used as a water supply source. When the cylinder 8 made of cotton nonwoven fabric or the like, which has roots, is carefully wound and unfolded thereon, the roots penetrate the seedling cultivation soil substitute molding material 3 and absorb water, so that seedlings can be raised similarly. It is also possible to develop a sprouting corner cylinder 8 such as a cotton nonwoven fabric in the long hydroponic bed for hydroponic seedlings.

As described in the paragraph [0018], when the thin cotton 4 for preventing root rising or the like is laid and covered with a cover 7 made of a polystyrene nonwoven sheet or polyethylene film through which shoots and roots do not pass, the gap between the thin cotton 4 causes electrothermal steam. In the seedling raising device A and the like, heat and oxygen are well transmitted to the seeds 5 in the cylinder 8, and sprouting and rooting are promoted. By pressing the cover 7, the seeds are buried in the thin cotton 4 and do not move, and the reinforcing action thereof makes it easy to wind up the cylinder 8, so that even a novice nursery worker can easily work.

When the raising of the seedlings is completed, the seedlings are tilted in the direction opposite to the winding direction, and are wound with the square pipe 10 made of aluminum or the like as a core. When the seedlings are rolled up and fallen in the opposite direction by the seedling winding roll 12, a phenomenon occurs. Seedlings that fall in the opposite direction are susceptible to damage by scraping by the transplanting nails of the transplanter / rice transplanter.

In order to prevent the seedlings from rising, a long cotton nonwoven fabric having biodegradability and capable of being separated and scraped by the transplanting nails of a rice transplanter / transplanter is used as shown in FIG. A creped paper or the like, a non-biodegradable film such as a polyethylene film, a non-woven fabric heat-treated sheet such as a polystyrene or the like is covered as a seedling pressing overlay 13.

A weight roll 14 for holding the seedling holding overlay 13 is provided in front of the winding direction of the long seedlings, and the seedling holding roll 13 is formed around the square pipe 10 to form a seedling winding roll 12 and wound. take. The cross section of the weight roll 14 may be polygonal as shown in FIG.
With the advance of the winding, the weight roll 14 is also rolled and sequentially advanced. As shown in FIG. 5, the seedling holding overlay 13 is pulled by the seedling take-up roll 12 and the weight roll 14, and the seedling holding overlay 13 is pressed from above so that the seedlings do not rise. Due to the pulling resistance of the seedling holding overlay 13, the long seedling mat can be firmly wound without extending vertically.

In order to easily knock down the seedlings, a movable edge 16 having a trapezoidal movable cross section that can be opened and closed by a spring hinge 17 is formed so that a space formed by a downward U-shaped cross section in the short side direction shown in FIG. And a seedling holding plate B provided with. Seedling holding plate B
The movable rim 16 is slid on the edge of the bordered seedling raising plate 15 so that the raised seedling is pushed down from one end of the bordered seedling raising plate 15. Since the cross section of the movable edge 16 is trapezoidal and narrowed inward, the leaf tip of the seedling 11 near the edge is pushed inward and falls, and does not protrude.

As shown in FIG. 7, the weight 19 or the scaffold or the like is placed on the seedling holding plate B, and the seedling holding plate B is fixed on the seedling raising plate 15. B descends vertically as a single plate, and the seedlings are flat and uniformly embossed with the weight of the weight 19 or the scaffold or the like, and become the knocked-down seedlings 11.

2, the seedling take-up roll 12 is moved to the front bearing hole 23 through the horizontal slit 24.
And the distance from the weight roll 14 is kept constant. D in FIG.
This shows a situation in which a long seedling that has been knocked down is taken up by a different-type seedling take-up device to which the weight roll 14 is fixed to form a seedling take-up roll 12. When the diameter of the seedling take-up roll 12 is small, this simple structure may be employed, in which the handle 21 is omitted and the seedling take-up roll 12 is directly turned by hand. Reference numeral 22a denotes a flange of the holding roll 22, which aligns the end faces of the seedling winding roll 12.

Another type of seedling take-up device E is shown in FIG.

If the seedling presser overlay 13 is biodegradable, it may be scraped off with the transplant nail 32 without winding. In this case, the seedling holding overlay 13 may be impregnated with a pesticide or the like to replace the pesticide application to the seedling box in the cultivated seedling. Reference numeral 31 denotes a rotating brush for preventing the displacement of long seedlings.

[0035]

The present invention is configured and implemented as described above, and produces the following effects.

[0036] Regardless of investment in a huge amount of hydroponic seedling facilities and winding machines, simple tools such as a conventional seedling raising device, a seedling holding plate obtained by cutting water-resistant plywood, a seedling holding plate, and an iron plate welding winder are used. Long seedlings can be grown by using commercially available seedling cultivation alternative molding materials and the like as a seedling raising base material, pushed down, embossed, wound, and transplanted.

Since the tension is applied to the seedling pressing overlay upon winding, it does not occur that the long rice seedling mat is stretched and narrowed.

[0038] Since the commercially available substitute material for raising seedling cultivation is wound around the underlay or the like and wound into a cylindrical shape and placed in the seedling raising device, rooting does not occur and the space for the seedling raising device can be saved.

Above all, after the germination, it is transported in the form of a cylinder, transported to a farmer's field, spread on a seedling plate arranged on a scaffold made of steel or the like, and seedlings can be raised in a heat insulation tunnel or the like as usual. The need for large greenhouses and greenhouses for greening of shelves that operate only for a short period of time, which are characteristic features of long-tiled seedlings (long mat seedlings), and that are hardened horizontally.

In addition, a large amount of cylindrical seedlings can be transported and deployed more easily as compared with the transport of heavy and difficult-to-handle budding seedlings and the growing in the farmer's field in the current cooperative nursery facilities. Transport of the hydroponics long mat seedling after sowing is impossible except by winding after the seedling is completed due to its soft nature of growing in water. Greening of large area
It is a configuration that requires a nursery space for hardening and the like.
