Description

[Detailed explanation of the invention] Conventionally, paddy is grown by scattering on a rectangular-shaped growing surface (also called the growing base material), and the seedlings are placed on the seedling mounting table of a rice transplanter along with the growing surface, and the mounting table is moved back and forth from side to side. A planting claw that moves up and down at a fixed position is used to grow, take out and transplant seedlings.

However, if the seedlings are sown in a rectangular shape, the seedlings in the center will grow slower than the surrounding seedlings due to poor air circulation, so it is preferable to sow in stripes.

However, when seedlings that have been sown in stripes and grown are placed on a seedling stand along with a growth plate, the roots of the seedlings are entangled and are plastic like clay, so each time the table moves back and forth, The left and right sides of the growth plate, which have the same dimensions as the mounting table, are alternately pressed against the left and right side plates of the mounting table, and the impact gradually compresses both the left and right sides of the growth plate, creating a gap between them and the side plates of the mounting table, which prevents the growth. At the outermost part of the top, the planting claws pinch this gap and the space between the seedlings, making it impossible to take out the seedlings correctly, resulting in missing plants.

The purpose of this invention is to prevent seedlings that are likely to occur when transplanting seedlings grown by sowing in stripes using a rice transplanter. When cultivating rice, paddy is sown in stripes between the ridges formed on the surface, and on the left and right sides of the surface there are wide areas that are wider and flat than the spacing between the ridges. It is characterized in that paddy is scattered in this wide part.

To explain the present invention with reference to the embodiment shown in Figures 1 and 2, 1 is a well-known rectangular growth made of fertilizer, paddy, pulp material, etc. The ridges 2 are formed at regular intervals, so that the paddy is sown between each ridge, and one or two ridges are missing from the left and right sides of the surface. A wide part 3 which is flat and whose width is wider than the fixed interval between the respective protrusions 2, 2 is formed, and paddy is sown on this part.

However, when paddy is sown at a uniform density over the entire surface of the growing ridge 1, the paddy on the ridges 2 will fall to the left and right, and the paddy will be sown in stripes between the ridges 2 and 2, and on the left and right wide areas 3. Paddy is scattered at the same density as between each row.

Therefore, if you cover the soil evenly and water it, the germinated seedlings will have good air circulation in the center, so you can get transplantable seedlings that will grow in the same way as the left and right seedlings and have a uniform height. It will be done.

When the seedlings have grown enough to be transplanted,
It contains water inside, and the roots of the seedlings become entwined with it, making it as plastic as clay.

However, when seedlings are placed on a seedling platform that reciprocates from side to side of the rice transplanter along with the rectangular growing device 1, when the platform moves back and forth from one side to the other, the reaction force causes the growing device to be pressed against the side plate of the platform. However, as mentioned above, the growth material 1 has plasticity, that is, it has the property of being permanently deformed by external force, so the left and right portions of the growth material 1 are gradually compressed (deformed) due to the impact (external force) received from the side plate of the mounting table. ), but the other parts are not compressed because the impact is absorbed by the compression of the left and right parts and is not transmitted.

In other words, the impact on the growth layer 1 by the side plates of the mounting table exclusively contributes to compression of the left and right portions of the growth layer 1.

In the present invention, flat wide portions 3, which are wider than the fixed spacing between the protrusions 2 and 2, are formed in advance on the left and right portions of the rectangular growth surface 1 to be compressed. Since paddy is sown at the same density as between each ridge, even if the wide part 3 is compressed and a gap is created between the left and right side plates of the seedling mounting table, the density of seedling vegetation in the wide part 3 will be reduced due to the compression. It will increase.

Therefore, in the outermost part 1 for growth, the planting claws pinch the wide part 3 where the vegetation density is high, so even if the planting claws pinch the gap between the side plate of the seedling table and the wide part, each protrusion You can pick out the same number of seedlings as you have between them.

However, in a conventional seedling raising mat that does not have the wide portion 3, that is, has protrusions at equal intervals over the entire surface, its left and right sides are pressed against the side plates of the mounting table and are compressed, creating a gap between them and the side plates of the mounting table. Since there are ridges without seedlings on both the left and right sides of the growing area, the density of seedling vegetation will not increase even if the area is compressed.

Therefore, at the outermost side of the growing field, the planting claws will grab the gap as well as the part where no seedlings are present, such as between the front and back of seedlings that have been sown in ridges or stripes. give rise to stocks.

However, when the present invention is used, when the wide portions 3 formed on the left and right sides of the seedling-raising mat are compressed, the density of seedling vegetation in that portion increases, so even if a gap is formed between the side plate of the mounting table and the side plate of the mounting table, plant loss will not occur. There isn't.

In short, the seedling growing mat according to the present invention forms a rectangular growing mat using a plastic material when transplanting seedlings,
Paddy is sown in stripes between the ridges 2 formed on the surface of the growth layer 1, and on the left and right sides of the surface of the growth layer 1, there are wide areas 3 that are wider and flat than the fixed spacing between the ridges 2. form,
Since paddy is sprinkled on this, when the seedlings grown in this way are placed on a rice transplanter and transplanted together with the cultivation stage 1, the wide part 3 of the cultivation stage 1 is damaged due to the impact caused by the reciprocating movement of the seedling table due to its plasticity. Even if the compaction increases the vegetation density of the seedlings in that area and, as a result, a gap is formed between the side plate of the mounting table and the growth top 1, seedlings will not be missing, and the seedlings will be correctly planted in a predetermined number at a time. This produces the effect that it is possible to

In addition, in the present invention, as shown in FIG. 3, by providing wide portions 4 not only on the left and right sides but also on the front and back, when a new growth top is spliced onto the mounting table, no stock will be missing at the spliced portion.
