Description

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

The present invention mainly relates to raising rice seedlings, and was invented as a countermeasure against cold damage in cold regions.

The seedlings loaded into the rice transplanter are grown in a shallow square box made of synthetic resin called a seedling box.

The seedling raising box has numerous drainage holes formed in the bottom plate.The seedling raising box is filled with bed soil, the surface of the bed is leveled and used as a sowing surface, rice seeds are placed on the sowing surface, and the seedlings are covered with soil. Water and grow.

The completed seedlings are called mat seedlings, seat seedlings, or futon seedlings because they are used by removing the soil from the seedling box.

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

Potted seedlings are made by unfolding a folded sheet of paper-like material on a spreading board like an accordion to form countless pots, and seedlings are sown into the pots.

This method has a drawback in that the seedlings grow uniformly and densely over the entire surface.

The present invention improves this point by allowing the seedlings to grow in a concentrated manner in the center of each pot, and making it easier to divide the seedlings.

In the present invention, a pot sheet made of a material such as the following 80 paper and having a through hole formed in the center of the bottom with a much smaller area than the bottom is placed on a board.

Sow the seeds on top of the soil filled with C0.

d. Fill bed soil over the sown seeds.

e. Cover the pot sheet with a synthetic resin seedling box,
Turn the whole thing upside down.

f. Remove the board and allow the seedlings to grow upwards from the through hole.

This is a seedling raising method that combines the following requirements.

To explain with a diagram, FIG. 7 is a perspective view of a pot sheet (11) used in the present invention, in which a large number of pots (2) are arranged side by side. , is formed into a conical shape, and a through hole (4) is opened in the center of the bottom plate (3).
) is much smaller than the area of

Then, place the bottom plate (3) of the pot sheet (11) face down on the board (5) as shown in Fig. 1, and fill the pot (2) with covering soil (6). Seeds (7) are sown on top as shown in Figure 3, and the bed soil (8) is then filled on top (Figure 4).

Next, cover the seedling box (9) from above, and place the board (5) at 180 m
'Turn it over to the state shown in Figure 5, remove the board (5), and grow seedlings. In such a case, the germinated leaf blade O1 grows by extending out from the small hole (4), so as shown in FIG. 6, it grows concentrated in the center of each pot (2),
As described above, the method of producing a well-grown tree with good sunlight and ventilation is characterized by the fact that the leaf blade a1 extends through the small perforation (4), resulting in concentrated seedlings and the ability to grow large seedlings.
