DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for cultivating natural potatoes which can simplify planting and harvesting operations and can harvest good quality potatoes.

[0002]

2. Description of the Related Art At present, the harvest of natural potatoes has been drastically reduced, and it has been common practice to harvest them by artificial cultivation.
A pipe made of vinyl chloride having a diameter of 5 to 6 cm and a length of about 1.3 m was continuously cut in the length direction by cutting slightly narrower than the diameter width. After being formed and cut out, soil for cultivation is put into the pipe, and a large number of soil-filled pipes are prepared in advance.

[0003] Then, a groove having a predetermined depth and a predetermined length is dug in the cultivation area so that the pipe is buried vertically at a predetermined angle.

[0004] Then, after burying this pipe in a state where a number of the soil-filled pipes are arranged in the groove, seed potatoes are planted on the surface of the pipe and covered with soil.
This seed potato gradually grows in the pipe, and a natural potato having a diameter smaller than that of the pipe and substantially the same length grows.

[0005] These planting operations are performed in the spring,
In the fall, harvesting of the native potatoes grown in a predetermined manner is performed, and at the time of harvesting, in order to take out the native potatoes grown in the pipes together with the pipes buried in the ground, the grooves are formed around the pipes. The cultivation area is dug up again to the buried depth of the pipe, and each pipe is pulled out.

[0006] Then, the cut of the pipe is pushed and spread, and from the cut, a wild potato grown together with the cultivated soil is taken out.

[0007] Therefore, when planting, a cut must be formed in each pipe in advance, so that the cutting process is troublesome, and the cultivated soil must be packed from the cut of the pipe. However, if the cultivation soil is difficult to pack and the cultivation soil is not completely filled, it adversely affects the growth of natural potatoes.

When harvesting the potatoes, the grooves formed in the cultivation area must be dug up again, so that this excavation work is heavy labor, and moreover, the soil-filled pipe filled with the potatoes has to be pulled out one by one. Harvesting of the potatoes planted in the country puts a greater labor burden.

[0009] In particular, every time a potato is planted, it is necessary to construct a groove in the cultivation area and to arrange and lay pipes, so that the labor burden on aging agricultural workers is inevitable.

[0010] In addition, since natural potatoes growing in the pipe are formed with continuous cuts in the length direction,
From this cutting, harmful substances such as fungi, pests, pesticides and the like in the soil invade and damage the growing natural potatoes, and also invade the toxicity of the fertilizer together with rainwater, and similarly have an adverse effect on the natural potatoes.

Further, in order to prevent harm to the natural potato caused by bacteria existing in the soil, the soil must be disinfected with a pesticide, so that the damage of the pesticide to growing natural potatoes is further increased. And other various problems.

[0012]

As shown in FIG. 4, a ventilation / water passage 2c may be provided at a position located on the rear side when the cylinder 2 is obliquely embedded.

The setting of the inner diameter of the cylindrical body 2 varies depending on the variety of the harvested potatoes, but what is necessary is that the diameter of the potatoes be larger than the most grown potatoes. The cultivation bag 3 in which the natural potato b grown from the inside is set so that a gap s having a minimum allowance for easy pulling is obtained. improves.

For example, if the maximum diameter of the potato b is about φ50, the inner diameter of the cylindrical body 2 is as follows.
A ratio of about φ70 to φ90 is preferable, but the ratio is not limited to these values since it has a relationship with the filling amount of the soil 9 from various growing conditions of the natural potato b.

The cultivation bag 3 has a natural potato b inside.
Is filled with a medium 9 suitable for cultivation of the above, and inserted into substantially the entire length of the cylindrical body 2 in the longitudinal direction, and a cylindrical vinyl bag having a predetermined strength and having a closed lower end is used. .

Then, one of the cylindrical bodies 2 prepared as described above is inserted into the mounting groove 1 in FIGS.
As shown in (b), a large number of openings 2a are buried side by side so that the openings 2a are located substantially at the surface of the cultivation ground 5, and the periphery of the cylindrical body 2 is Cultivated land 5 excavated so that soil does not enter body 2
Backfill the soil and keep the surface flat.

Further, the cultivation bag 3 made of vinyl is filled with the soil 9, and a number corresponding to the number of the cylindrical bodies 2 buried in the cultivation area 5 is prepared.

As shown in FIG. 5 (c), these cultivation bags 3 are inserted into the cylindrical body 2 one after another through the openings 2a. Moreover, since it is formed thinner than the inner diameter of the cylindrical body 2 by the temporary fixing 3a, the insertion is easily performed even if the weight of the cylindrical body 2 is lowered, and furthermore, the end of the cultivation bag 3 is formed a little longer and the ground surface portion is formed. If the cultivation bag 3 is pulled out by grasping the exposed portion, the work is easy.

A cover member 1 made of a vinyl sheet (multi) for preventing pest infestation is placed on the cylindrical body 2 containing these cultivation bags 3.
2 and cover the soil 13 with a thickness of about 6 to 7 cm. Then, the seed potato 4 grown in advance is planted on the soil 13 as shown in FIG.

The cover member 12 is also useful for preventing the soil 9 or the soil of the cultivation area 5 or the cover soil 13 from entering the gap s between the cultivation bag 3 and the cylindrical body 2.

This completes the planting of the seed potato 4 of the natural potato b and waits for growth while performing predetermined management.
Normally, this planting work is performed in the spring and raised until the fall.

At this time, as shown in FIG. 7, the germinating spheres 4a of the seed potato 4 extend the buds of the new potato toward the bottom as shown in FIG.

As shown in FIGS. 7 and 8, when the natural potato b reaches a predetermined growth in the cultivation bag 3 along the cylindrical body 2, that is, when it is in the fall, FIG.
As shown in (a), the cover 13 and the cover member 12 are removed to expose the opening 2a of the cylindrical body 1, and the opening 2a is removed.
When the upper part of the cultivation bag 3 protruding from the a is grasped and pulled up, the natural potato b is removed from the cultivation bag 3 from within the cylindrical body 1.
Is taken out.

As shown in FIG.
As shown in (b), even if young or elderly, the natural potato b can be easily taken out by a simple and slight pulling force, and the harvest of the natural potato b is completed.

In the next cultivation of the potato b,
Since the cylindrical body 2 has already been buried first, it is possible to insert the cultivation bag 3 filled with the soil 9 into the cylindrical body 1 from the state shown in FIG. ,
Furthermore, the work of planting the seed potatoes 4 becomes simpler, and the agricultural work that tends to be heavy labor that requires a large amount of power is greatly reduced.

[0047]

As described above, the method for cultivating natural potatoes according to the present invention is as simple as inserting a potato cultivation bag into a cylindrical body buried underground through an opening thereof when planting potato seeds. Preparation for planting is simple, and cultivation soil can be easily packed.

When harvesting the potatoes, the grown potatoes can be taken out only by pulling up the cultivation bag from the cylinder, so that the grooves formed in the cultivation area do not have to be dug up again, and the harvesting of the potatoes planted in large quantities can be easily carried out. ,
Work load can be significantly reduced, and even young and elderly people can engage in cultivation work.

In particular, once the groove in the cultivation area is constructed and the cylinder is buried, the next time the potatoes are planted, the groove in the cultivation area and the already buried cylinder can be repeatedly used. In addition, the labor required for planting work can be greatly reduced, and the labor required for the construction work of the groove and the pulling out of the cylindrical body is not required, so that a great reduction in labor load can be achieved.

Since the opening of the cylindrical body is as small as possible, damage to the growing natural potatoes and deterioration in quality due to invasion of harmful substances such as soil bacteria, pests, and pesticides can be achieved. Since it is not necessary to disinfect the soil with a pesticide for controlling bacteria existing in the soil, the damage of the pesticide to the potatoes is further reduced.

By providing a growing groove near the mounting groove along the mounting groove, the fine roots grown and extended from the seed potatoes can be easily stretched on the surface of the ground and formed in a groove shape, and the fine roots are stretched. The area can be enlarged as much as possible. And so on.
