Description

[Detailed description of the invention] The present invention relates to a method for raising seedlings and a pot sheet.

The present invention mainly relates to a seedling-raising method for growing seedlings to be attached to a rice transplanter, and a pot sheet.

Normally, seedlings for rice transplanters are grown in a shallow square box made of synthetic resin called a seedling box.

The seedling raising box has numerous drainage holes formed at the bottom, and the bed of the seedling raising box is filled, the surface of the bed is leveled to form a sowing surface, and the rice seeds are sown on the sowing surface and covered with soil. water,
Cultivate.

The finished seedlings are called mat seedlings or zabuton seedlings because they are used by removing the entire top from the seedling box, and the rice transplanter uses its planting device to gradually remove the mat seedlings, including their roots, from the edge. Cut and plant rice.

In comparison to mat seedlings, what is called pot seedlings has also become quite popular.

Potted seedlings can be transplanted into rice without cutting the roots like the matted seedlings, so they grow well after rice planting, and are widely used, especially in regions where they grow lightly, such as in cold regions.

Conventional potted seedlings are made by unfolding a folded sheet of paper-like material on a spreading plate like an accordion to form countless pots, and then sowing seeds into the pots to form potted seedlings. 0 This method requires folded sheets to be unfolded one pot at a time like an accordion, so
It's quite a hassle. Therefore, we formed something that looked like it had been developed from the beginning using a thick and stiff material, and developed a technology for applying it.

That is, a pot sheet is formed from the beginning with a stiff and thick material such as cardboard. The pot sheet is
It consists of many pots arranged side by side. A pot is like a pot. Seeds are sown on the bed inside the pot, covered with soil, and then germinated to become potted seedlings. However, when growing potted seedlings on a W box, the process is reversed. When made into a pot,
Seeding work becomes easier. In other words, if you sow the seeds in the pot first on the bed, then sow the seeds on top of the bed, then cover it with soil and transfer it to the seedling box, as described above, it will be difficult to transfer the pot sheet to the seedling box. Yes, but in the pot;
- When sowing seeds, first put in a covering soil, sow the seeds on top of it, fill the bed, tear up the seedling box from above, and turn the seedling box and pot sheet upside down. This allows the pot sheet to be moved into the seedling box very easily. When using this method, the leaf blades of Camellia f that have germinated in the pot will grow through the bottom of the pot, so there are small holes and holes in the low wall of the pot to facilitate the growth of the leaf blades. It's a good idea to keep it. The smaller the holes are, the closer the leaf blades are to the center, which increases the effectiveness of spot sowing. Therefore, a pot sheet is formed with small perforations of about 3 or 5 m in diameter, but when the perforations are small like this, it is difficult for the tips of the germinated leaves to find the small perforations, causing them to wither. The present invention has been devised in this respect.

The present invention involves forming the low wall of a pot made of paper-like material into an arcuate wall, forming a small through hole in the center of the pot, filling the pot with soil, and then covering the pot with soil. Seeds are sown on top of the seedlings, and then the seeds are placed on the bed to fill the pot, a seedling box is placed over the top of the pot, the lid is closed, and the pot and seedling box are turned upside down to grow. The seedlings are raised by the circular arc wall of the bottom wall of the pot sheet, gathering in the center and extending upward from the small through hole, and the bottom wall of the pot is made of a stiff material such as cardboard. A small through hole is formed in the center of the circular arc wall, and a large number of such pots are arranged side by side, and each pot is integrally connected to each other at its upper edge.

To explain with a diagram, (1) shows the entire pot sheet. The sheet +11 is made of a stiff material such as paper, and its size is such that it fits perfectly into the seedling box (2). The sheet +11 has a large number of pots (
3). The pot (3) is formed to have a smaller diameter as it reaches the bottom wall (4), and the bottom wall (4) can be formed into an arcuate wall (5).

A small through hole (6) is formed in the center of the bottom wall (4). The pot (3) is attached to the adjacent pot (3) at its upper edge (7).
). In other words, it can be said that a large number of pots (3) are formed by pressing ~ sheets of thick paper-like material from above. Since the pot sheet (1) is like thick paper, it will tear if it gets wet with water, and will rot after a long period of time. The space immediately above the bottom wall (4) in the pot 3) is a soil-covering chamber (9) into which the soil-covering soil (8) is placed, and a seed chamber a3 in which the seeds Q (Ik) are sown, above which is filled with bed soil aa. This will be the above-floor room Q31.In the figure,
α4 is a leaf blade, α9 is a radicle, αG is a drainage hole, and +171 is a mounting table.

Next, we will discuss the effect.

The bot sheet CI) made of paper-like material formed as described above is placed on the mounting table (17+) as shown in Fig. 2, and the soil covering (8) is poured into the soil covering chamber (9) from above. If the soil is poured in first, the covering soil (8) will be stored in the soil-covering chamber (9) on the bottom wall (4) of the pot (3).Next, if the seeds αq are similarly introduced from above, each pot ( 3) Seeds are sown inside the seed chamber αυ and spot sown.

After sowing the seed decoys, add bed soil O2 on top of them. Next, level the top part of 02 on the floor and remove the excess bed soil O3.
After removing the seedlings, cover them with a seedling nursery box (2). The seedling raising box (2) is the same as the conventionally popular one, is made of synthetic resin, and has numerous drainage holes ae. Cover this completely from above the pot sheet fl),
Cultivate it by turning it upside down as shown in Figure 6. Then, the germinated leaf blade 0I grows inside the bottom wall (4) and forms an arcuate wall (5).
The seedlings are guided inside the hole and extend upward through the small through hole (6) to obtain potted seedlings. The obtained potted seedlings are placed on the seedling tank of the rice transplanter, and are cut into pieces by a planting device (3) and planted.

The present invention is as described above, and in particular, the bottom wall (4) of the pot (3) made of a material such as paper is formed into an arcuate wall (5), and a small through hole f61 is formed in the center of the bottom wall (4) of the pot (3). A soil cover (8) is poured into the pot (3), and then a seedling is sown on the soil (8). The seedling box (2) is placed over the top of the pot (3) to form a lid, and the pot (3) and the seedling box (2) are turned upside down and grown, and the germinated seeds a0 leaf blade a4 is a seedling raising method in which the circular arc wall (5) of the bottom wall (4) of the pot sheet il+ is guided, the seedlings gather in the center and extend upward from the small through hole (61), and are made of a stiff material such as cardboard. The bottom wall (4) of the pot (3) is formed into an arcuate wall (5), and a small through hole +61 is formed in the center of the bottom wall (4).
) are integrally connected to each other at their upper edges (7'') to form a pot sheet, so for the above-mentioned seedling-raising method, they can be folded and unfolded like a paper pot, as in the case of a conventional paper pot. Since there is no need to expand the seedlings on the pot sheet (1), it is possible to greatly reduce the work effort. ). In addition, the germinated seeds a [leaf blade α4 is a small through hole (6) made in the bottom wall (4).
However, if the bottom wall (4) is flat, the tip of the leaf blade a41 may not reach the small perforation (61) and may die in the pot (3). but,
The bottom wall (4) with the small through hole (6) of the present invention is an arcuate wall (5
), the tip of the leaf blade a- extending along the arcuate wall (51) inevitably reaches the small through hole (6) and reliably extends upward.

In this way, the present invention guides the leaf blade α4 inside the arcuate wall (5) to reach the small through hole (6), so it can be carried out even if the small through hole (6) is made very small. When the small hole (6) is made smaller, the leaf blade a4 gathers in the center as shown in Figure 7.
This allows for good ventilation and good growth.
