[Industrial applications]

 The present invention relates to a seeding hole forming protrusion for seeding a seedling raising container, which is composed of an assembly of a large number of divided seedling raising pots.

[0002]

[Prior art]

 For sowing seedling containers that have been conventionally filled with soil, sowing is performed in advance by supplying the bed soil to the seedling growing container without filling the bed soil with the depth of the cover soil, and by seeding or spreading seeds on the bed soil. However, even if it is a covered seedling, a so-called plug seedling raising seedling container or a collective pot body for transplanting seedlings that has a large number of paper barrel pots in which a large number of synthetic resin pots are grouped and assembled. Similarly, the method of sowing and opening the soil to cover the soil and supplying the bed soil is used.However, this method is mainly used for transplanting seeds even when a plurality of seeds are solidified in one place, such as paddy rice. It is convenient because it is transplanted as a single strain in a stable condition, and is a bed soil supply method that is commonly used in the seeding method that does not pose a problem in terms of growth.

[0003]

[Problems to be Solved by the Invention]

 On the other hand, when sowing two or more seeds in one pot such as a vegetable, the collective pot is placed on a plate provided with a large number of protrusions corresponding to each pot as shown in Japanese Utility Model Publication No. 48-3300. It has been practiced to insert the seeds into the pots by filling them with soil and then reversing the soil after filling it with soil and removing the protrusion plate upwards to form seeding holes corresponding to the protrusions. It is also practiced to make a seeding hole by inserting a seeding hole projection into a seedling-growing container filled with bed soil that runs on a conveyor, and sowing the hole. When seeding a plurality of seeds in such a vegetable, since these are transplanted without thinning out one by one before transplantation, it is necessary for each offspring to grow individually as a growing seedling. Since the center of the bottom of the sowing hole with the sowing hole projections is deep, the seeds are often concentrated in the center of the bottom of the sowing hole. The seeds sown by the grain cannot grow.

[0004]

[Means for Solving the Problems]

 As a result of diligent research conducted by the inventors to correct the above situation, a seeding hole forming projection that penetrates into a pot filled with bed soil to form a seeding hole has a recessed portion on its tip surface. By forming a hill shape at the bottom of the sowing hole formed in the potted soil and forming a corridor-shaped seed groove around the hill shape, it is possible to eliminate the concentration of multiple seeds in the center. I was able to do it. That is, the concave part provided on the tip end surface of the projection is so arranged that seeds that fall from the top of the hill-shaped bottom of the sowing hole formed in the soil of the pot are slid in four directions along the slope of the hill and placed in the seed groove. Therefore, it is sufficient that the seed has a tilt angle that allows the coated seeds to rotate and fall, and therefore the hill-shaped sloping surface is usually formed in a hemispherical shape, but it is conical or A pyramid shape may be used, and a concave portion having a shape corresponding to this can be provided on the tip end surface of the protrusion to penetrate into the soil surface of the floor of the pot to form a hill shape at the bottom of the seeding hole. is there.

The seeding hole forming projections having recesses on the tip surface are usually fixed on the base plate at a predetermined pitch, and the length of these projections and the size of the recesses are different from those of the seed crop. Although it may differ, the total length of the protrusion is usually 6 to 10 mm, the diameter of the recess is 8 to 11 mm, and the depth is about 2 to 4 mm. The pitch when the protrusions are fixed on the base plate is the pitch of a collective pot for transplanting seedlings that is a large number of paper pots or a plug pot where a large number of synthetic resin pots are divided. The piercing plate is pierced from the upper surface of these collecting pots that are filled with floor soil, or in the case of a bottomless collecting pot, the collecting pot is fitted from above the protruding plate. Next, it is possible to form a hill-shaped seeding hole at the bottom of the seeding hole by filling the bed soil, covering the seedling growing box and turning it over, and then removing the projecting plate. It is also possible to form a seeding hole by arranging a seeding hole forming projection with a recessed part on the tip surface of the seedling and penetrating it into a seedling raising container such as a collecting pot body filled with the bed soil transferred on the conveyor. It is a thing. The projections of this invention are commonly used to form seed holes for vegetable crops such as green onion, leek, spinach, honeysuckle, and flowers, for which seeds are used for seeding. Anything that rolls down the inclined surface of can be used.

[0006]

[Action]

 This invention corresponds to the case of seeding a seedling-growing container such as a divided pot body assembly made of paper or synthetic resin, so that the seeding hole in the filled bed soil corresponds to a hemispherical, conical or pyramidal tip. Since the seeding holes were formed by the seeding hole forming projections with the recesses, the bottom part of the seeding holes had a hill shape with an inclined surface on which the seeds falling from the top could easily roll off in all directions. Since it becomes a corridor-shaped seed groove, seeds that fall from the hill shape will remain in a stable state.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 is a base plate, and 2 is a seeding hole forming projection fixed to the base plate 1. The seeding hole forming projections 2 are usually in the shape of a cylinder or a bowl, and are fixed in a large number at predetermined intervals according to the pitch of a seedling raising collecting pot (not shown). As shown in FIGS. 2 and 3, a concave portion 3 is provided at each tip of the projection 2 for use. As shown in FIG. 4 and FIG. 5, when the seeding hole forming projection 2 penetrates into the bed soil 5 filled in the pot body 4 to form the seeding hole 6, the concave portion 3 is formed on the bottom of the seeding hole 6. A hill portion 7 corresponding to the recess 3 of the sowing hole forming projection 2 is formed, and a seed groove 8 is formed in a corridor shape around the base of the hill portion 7. As a result, when a plurality of seeds 9 are sowed in the pot 4 from above in the sowing holes 6, the seeds 9 roll down from the hill portion 7 to the surroundings and are stably placed in the seed groove 8 formed at the base of the hill portion 7. It will be placed later.

When a pot for raising and transplanting seedlings having a large number of paper cylinders is used as the pot 4, 10 is an L-shaped comb tooth for fixing the side end row pot, It is attached to both ends. The present invention is constructed as described above, and a collecting pot for raising seedlings (not shown) is developed, and one end of the collecting pot is locked to one L-shaped comb tooth 10, so that the multiple end of the collecting pot for raising seedlings is fixed. After engaging with the other L-shaped comb tooth 10, after filling the soil 5 from above to sufficiently suppress it, cover the upper surface with a seedling raising box (not shown), and then collect the seedlings together with the base plate 1 for raising seedlings. When the pots are sandwiched and inverted, and the collecting pots for transplanting seedlings are placed on the seedling raising box and the base plate 1 is pulled up, the seeding holes 6 formed by the projections 2 are formed in each pot 4. 4 and 5, a hill portion 7 is provided, and a seed groove 8 is formed around the base portion. Then, using seedling hole slide type seeder, 5 seeds of green onion coated seeds were placed in each pot 4, and they did not gather in the center of the bottom of seeding hole 6 and fell into seed groove 8 at appropriate intervals. It was able to sow.
