Description

[Detailed description of the invention] The present invention relates to a row sowing method using a seedling raising box.

Current rice transplanters use seedlings grown in shallow synthetic resin boxes called seedling boxes.

When using a rice transplanter to shield seedlings grown in a seedling nursery box, the shielding claws are used to cut off the soil little by little from the edge and drop it onto the surface, so the growth in the nursery box is uniform. It is hoped that you will be like me. Therefore, when sowing seeds on the sowing surface of the seedling box, it is necessary to carefully spread the seeds so as not to spread them unevenly in any part, but no matter how carefully you rake, you can expect more than a certain amount of work. Therefore, research on sujimaki is being actively conducted. Row sowing is a method in which parallel grooves are provided on the sowing surface and seeds are sown within the grooves.

Experiments have shown that seedlings sown in rows grow better and are more durable than those sown in individual rows.

In other words, since the hollyhock is in rows, there is good ventilation between the hollyhock sides, and more water evaporates than the straw side, which improves plant physiology.
Very good results can be obtained. Now, the problem is how to add streaks in the seedling nursery box. The easiest way to create parallel grooves on a seedling box is to use a comb-tooth leveler.

When you strike the ground with a hard stick, a line is drawn there,
The part of the drawn line becomes a groove. However, this groove lacks precision. It is most difficult if the ground is soft, like ash. It is true that when leveling the ground with a comb-shaped leveling tool, parallel combs are formed on the ground, but if the soil is like ash, the grooves will quickly collapse, and In this sense, it is nothing more than a groove-like formation. If you were given the problem of creating a parallel groove with the same dimension lw/surface deviation by giving the dimensions of the groove bottom regarding the cross-sectional shape of the groove, in order to solve the problem, it would be necessary to in,
This method of covering the ground is not a problem at all.

Therefore, to explain the devised invention of the present invention, the present invention fills the seedlings in a shallow synthetic resin seedling raising box, and then uses a leveling tool to remove the portion corresponding to the soil covering layer to create a flat seedling grower. A lattice-shaped groove formed by arranging a large number of horizontal machines in parallel is sent out on the sowing surface of the surface of the grower layer, and a knight is formed between the horizontal layers of the groove-formed odor. This is a row sowing method for a seedling raising box in which parallel grooves are created in the seedling raising box by removing the groove forming odor after filling the seedling raising box and sowing seed rice in the parallel grooves.

That is, a seedling raising box 1 made of synthetic resin and having a shallow drawer shape is filled with knights to a heaping degree, and then the seedlings are leveled with a leveling tool 2.

Leveling tool 2 uses one with a horizontal bottom edge, but the work is as follows:
In addition to simply flattening the soil surface, the soil covering layer A
The soil is removed so that only the grower layer B is left inside the seedling growing box 1.

Generally, commercially available seedling growing boxes are all made according to the standard, so the depth D is approximately 30 m/skin, and the grower layer B is about 2 mounds thick. .

In this case, the upper surface of the grower layer B becomes the horizontal seeding surface 3, but the seeds are not sown immediately, but the grooves 5 are formed using the groove forming tool 4 shown in FIG. 8.

The groove forming tool 4 has a special shape, and has ears 7 at both ends that can be placed on the greenery 6 of the seedling growing box 1, and when the ears 7 are placed on the seedling growing box 1, the lower surface 8 A large number of horizontal machines 9 are arranged side by side in close contact with the seeding surface 3. The lower surface 8 of the horizontal machine 9 is in close contact with the seeding surface 3, but the cross-sectional shape is formed in a tapered shape that becomes wider toward the top, and the upper surface 10 is larger than the lower surface 8. A groove 11 is formed between one horizontal machine 9 and the next horizontal machine 9, but instead of sowing seeds, the groove 11 is filled with soil. That is, when the groove-forming odor 4 formed as described above is spread on the seedling-growing box 1, and the knight is filled with soil using an appropriate method and leveled, the groove between the horizontal machines 9, 9 is formed. Since the saved soil supplied later will be placed in the container 11, the condition will be as shown in Fig. 3. In this state, if the groove-forming odor 4 is gently removed, parallel grooves 5, 5, . The streaking method of the present invention is very rational, and when it is closely observed, several excellent points can be found.

Its first advantage is that the grooves 5, 5 can be formed accurately. When forming grooves on the other side, when using the method of forming grooves by digging them, no matter how careful you are, there is a phenomenon of collapse and it is not accurate, but in the case of the present invention, the method of forming grooves in a parallel state is not accurate. Since the method involves filling the groove 11 between the horizontal bars 9 and 9 with soil to create a mountain, and later making the groove between the horizontal bars 9 and 9, the groove is extremely accurate. When forming the parallel grooves 5, 5, the horizontal machines 9, 9 are in close contact with the sowing surface 3 as shown in Fig. 2, and the soil is inserted between them. The part of the bottom of the furrow where the seeds are sown will not be strongly pressed by the lower surface 8 of the horizontal machines 9, 9.
Therefore, the grooves 5, 5 have a fluffy feel, which is extremely convenient for plant growth.
