Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. In addition, this invention is not limited to the example of the following forms.

(Overall structure)
The yam cultivation apparatus 1 of the present invention cultivates yam inside a cylindrical body 3 embedded in the ground. Both ends of the cylindrical body 3 are open,
A cylindrical cultivation tube 9 is provided inside the cylindrical body 3,
The overall length of the cylindrical body 3 and the overall length of the cultivation tube 9 are substantially the same,
One end 9a of the cultivation tube 9 is close to one end 3a of the cylindrical body,
A lid 5 having a through hole 13 is detachably fitted to one end 3a of the tubular body 3 adjacent to one end 9a of the cultivation tube 9,
In the through-hole 13 of the lid portion 5, the new rod introduction hole 15 in the new rod guide means 7 having the new rod receiving portion 17 at one end and the new rod introduction hole 15 at the other end is fitted,
The end portion 21 of the new rice bran introduction hole 15 reaches the inside of the cultivation tube 9,
The Xinjiang receiving portion 17 is a plate-like body that is curved along the circumferential direction of the cylindrical body 9 and includes an opening 19 on the upper surface (see FIGS. 1 to 5).

(Material, length, diameter of cylindrical body)
Since the cylindrical body 3 is used for a plurality of years while being buried in the ground, the tubular body 3 is made of a material that has a strength that does not deform in the ground and that is less likely to deteriorate over time due to corrosion, temperature, or the like. Examples include metals that are difficult to corrode, metals that have been rust-proofed, and synthetic resins, preferably aluminum, iron that has been rust-proofed, polypropylene, polyvinyl chloride, polymethacrylic acid esters, polystyrene, polytetrafluoroethylene, Polyethylene terephthalate, polyamide, polycarbonate, etc. A commercially available polyvinyl chloride pipe may be used after processing.

The cross-sectional shape of the cylindrical body 3 is not particularly limited, and may be a substantially circular shape, a substantially elliptical shape, a substantially polygonal shape, or the like, preferably a substantially circular shape. The length of the cylindrical body 3 may be longer depending on the length of the yam to be cultivated, and an appropriate one may be selected according to the yam to be cultivated. What is necessary is just to select a suitable thing for the internal diameter of the cylindrical body 3 according to the thickness which the yam to grow grows. As will be described later, when cultivating yam using the yam cultivation apparatus 1 of the present invention, harvesting of yam is performed by pulling out the cultivation tube 9 from the cylindrical body 3, and therefore the inner diameter of the cylindrical body 3 is The outside diameter of the cultivation tube 9 when the yam grows most in the cultivation tube 9 is assumed to be larger. As an example, the inner diameter of the cylindrical body 3 is about 15 mm to about 20 mm larger than the outer diameter of the cultivation tube 9 when the yam grows most in the cultivation tube 9.

  The cultivation tube 9 is provided inside the cylindrical body 3 and is preferably flexible and impermeable. As will be described later, when cultivating yam using the yam cultivation apparatus 1 of the present invention, the yam is harvested by pulling out the cultivation tube 9 from the cylindrical body 3, and therefore the cultivation tube 9 is cultivated in yam. It is preferable that the material does not break due to deterioration during the period. Examples of the material of the cultivation tube 9 include synthetic resins such as polyethylene, polypropylene, polyvinylidene chloride, and polytetrafluoroethylene.

  The total length of the cultivation tube 9 is approximately the same as the total length of the cylindrical body 3 as an example. What is necessary is just to select an appropriate inner diameter of the cultivation tube 9 according to the thickness which the yam to grow grows. As will be described later, when a yam is cultivated using the yam cultivation apparatus 1 of the present invention, the yam grows with the inside of the cultivation tube 9 so that the yam grows most. It is preferable to make it larger than the outer diameter of the yam.

The cultivation tube 9 has a cylindrical shape, and one end 9 a of the cultivation tube 9 is brought close to one end 3 a of the tubular body 3. As will be described later, since the end portion 21 of the fresh potato introduction hole 15 in the new potato receiving portion 17 passes through the one end 9a and reaches the inside of the cultivation tube 9, as one example, A holding means for holding the size through which the end portion 21 penetrates is provided. The holding means is not particularly limited, and as an example, a flexible guide 11 is inserted into one end of the cultivation tube 9 (see FIG. 4). As another example of the holding means, the lid 5 A projecting portion 25 in which one end 9a of the cultivation tube 9 is fitted at a position on the outer periphery of the through-hole 13 and in contact with the inside of the cylindrical body 3 when the lid portion 5 is fitted to the cylindrical body 3. (See FIG. 7).

  The lid portion 5 having the through hole 13 is detachably fitted to the one end 3a of the cylindrical body 3. By fitting the lid portion 5 to the tubular body 3, soil is prevented from entering the tubular body 3 when cultivating the yam using the mountain cultivating apparatus 1 of the present invention. (See FIGS. 1 to 5).

  The position where the through-hole 13 is provided in the lid 5 is not particularly limited, and is, for example, a substantially edge portion of the lid (see FIG. 4). As an example, the inner diameter of the through-hole 13 is set to a size such that the outer diameter of the new rod introduction hole 15 in the new rod guide means 7 can be fitted.

The Xinjiang guide means 7 includes a Xinjiang receiving portion 17 at one end and a Xinjiang introduction hole 15 at the other end. The new culm introduction hole 15 is fitted into the through hole 13 of the lid 5, and the new culm introduction hole 15 passes through the through hole 13 and the end 21 reaches the inside of the cultivation tube 9. The Xinjiang receiving portion 17 is a plate-like body that is curved along the circumferential direction of the cylindrical body 9 and has an opening 19 on the upper surface. As an example, the new soot guiding means 7 is formed so as to gradually decrease in diameter from the edge 19a of the opening 19 toward the end 21 of the fresh soot introduction hole 15. As shown in FIG. 6, the Xinjiang guiding means 7 can be easily created by rounding a flexible flat plate 23 such as a synthetic resin and overlapping both corners.

  The inner diameter of the end portion 21 of the fresh potato introduction hole 15 in the fresh culm guidance means 7 is the inner diameter through which the fresh potato 57 grown from the seed potato 45 can pass when the yam 63 is cultivated using the yam cultivation apparatus 1 of the present invention. However, in order to prevent the cultivation soil 51 from entering the cultivation tube 9 from the fresh rice bran introduction hole 15 as much as possible, it is preferable to make the gap between the new rice cake 59 and the end 21 as small as possible. (See FIGS. 12 and 13). By preventing the cultivated soil 51 from entering the inside of the cultivated tube 9, it is possible to prevent damage to the yam that grows inside the cultivated tube 9 due to nematodes and pathogens contained in the cultivated soil 51. As an example, in the case of natural selection, the inner diameter of the end 21 is about 20 mm for the upper limit and about 15 mm for the lower limit.

  Next, the example of the cultivation method of the yam using the yam cultivation apparatus 1 of this invention is demonstrated.

The cylindrical body 3 having both ends opened is embedded in the ground 31 with one end 3a of the cylindrical body 3 protruding from the ground surface 33 and tilted so that the other end 3b is lowered. As an example, the angle 43 between the cylindrical body 3 and the horizontal plane 35 is set to an upper limit of about 35 degrees and a lower limit of about 15 degrees. (See FIG. 8).

)
A cylindrical cultivation tube 9 having substantially the same total length as that of the cylindrical body is filled with a soil 39 containing water having an upper limit of 30% by mass and a lower limit of 8% by mass in a flat plate shape. Preferably, the soil 39 has a substantially uniform thickness, and the flat soil 39 and the cultivation tube 9 are brought into close contact with each other. The thickness of the soil 39 is, for example, an upper limit of about 20 mm and a lower limit of about 8 mm. As an example, the soil 39 is not contaminated with spoilage bacteria or nematodes that adversely affect the growth of yam. Preferably, the soil 39 is heated.

The cultivation tube 9 filled with the soil 39 is inserted into the cylindrical body 3 such that one end 9a thereof is close to the one end 3a protruding from the ground surface 33 of the cylindrical body 3. As described above, for example, the guide 11 is fitted to the one end 9a. The soil 39 containing moisture does not descend in the cultivation tube 9 because it is in close contact with the inner surface of the cultivation tube 9 except for the vicinity of the one end 9a. Therefore, the soil 39 can maintain a state with a substantially uniform thickness inside the cultivation tube 9 (see FIG. 9).

The lid portion 5 having the through hole 13 is fitted into one end 3 a protruding from the ground surface of the cylindrical body 3. At this time, as an example, the through hole 13 communicates with one end 9a of the cultivation tube 9 (see FIG. 10).

The through hole 13 of the lid part 5 is fitted with the new rice cake introduction hole 15 in the new rice cake guiding means 7 having the new rice cake receiving part 17 at one end and the new rice cake introduction hole 15 at the other end, The end part 21 of the new culm introduction hole 15 reaches the inside of the cultivation tube 9 (see FIG. 10).

A seed potato 45 is planted above the new rice cake receiving portion 17 which is a plate-like body curved along the circumferential direction of the cylindrical body 3 and has an opening 19 on the upper surface. The seed culm 45 is planted so that the germinating sphere 47 is located above the new culm receiving unit 17. As an example, the seed culm 45 is planted by covering the new culm receiving portion 17 with the soil 9, placing the seed culm 45 thereon, and then covering the seed culm 45 with the soil 9. At that time, in order to position the germinating sphere 47 above the new rice cake receiving portion 17, a mark rod is set near the center of the new rice cake receiving portion 17. As described above, the soil 9 is not contaminated with spoilage bacteria or nematodes that adversely affect the growth of yam. By covering the Xinjiang receiving portion 17 with a soil 9 that does not contain rotting bacteria or nematodes that adversely affect the growth of the yam, the rotting fungi and nematodes that adversely affect the growth of the yam inside the cylindrical body 3. And the like can be prevented (see FIG. 11).

The upper side of the seed potato 45 is covered with the cultivation soil 51, and the yam is cultivated. While being careful not to move the planted seed culm 45, it is covered with cultivated soil 51 to form a culm 53 (see FIG. 11). One end 3 a of the cylindrical body 3 is covered with the lid portion 5, and since the Xinjiang introduction hole 15 is fitted in the through hole 13 of the lid portion 5, the cylindrical body 3 is embedded with the cultivation soil 51. However, the cultivated soil 51 hardly enters the inside of the cylindrical body 3. In addition, what is necessary is just to perform cultivation of a yam according to the normal cultivation method as an example.

Nutrient-absorbing roots 55, new shoots 57, and new shoots 59 grow from germination balls 47 of seed pods 45 embedded in cultivated soil 51. The nutrient absorption root 55 is a thin root and extends near the ground surface. New shoots 57 sprout from the surface. The Xinjiang 59 extends in the direction of gravity (downward) and reaches the Xinjiang receiving unit 17. The new rice cake 59 that has reached the new rice cake receiving portion 17 is blocked by the curved portion of the new rice cake receiving portion 17 and cannot extend outward from the new rice cake receiving portion 17, and the new rice cake introduction hole 15 tilted downward. It extends by being guided to the inside of the cultivation tube 9 through the end portion 21 of the fresh culm introduction hole (see FIG. 12). As an example, when the new rice cake receiving portion 17 is covered with the soil 9 and the seed potato 45 is planted above the edge 19a of the opening 19, the nutrient absorption root 55 extending near the ground surface extends above the edge 19a of the opening 19. To go. As a result, the nutrient absorption root 55 can be prevented from entering the inside of the cultivation tube 9 from the new rice cake receiving part 17 through the new rice cake introduction hole 15. After the seed culm 45 is planted, watering or fertilization is performed, and a net of the vine 61 is provided, whereby the new culm 59 grows into a mountain culm 63 inside the cultivation tube 9 (see FIG. 13).

According to the cultivation method of the present invention, the cultivated soil 51 hardly enters the cultivation tube 9, so that it is possible to prevent the yam 63 being cultivated from being damaged by nematodes and pathogens in the cultivated soil 51, High quality yam can be cultivated. Since the cultivation tube 9 is cylindrical, water does not accumulate in the cultivation tube 9 due to watering during cultivation, and the yam 63 in the cultivation tube can be prevented from rooting. In addition, since it grows inside the cylindrical body 3, it is not affected by the weight of the stones and soil in the ground 31 and the mountain foot 63 is not deformed, and a good quality mountain foot 63 having a substantially circular cross section is cultivated. (See FIG. 16).

  The mountain 63 is harvested in time for the harvest time. When the grown yam 63 is harvested, the vine 61 and the nutrient absorption root 55 are removed, the cultivated soil 51 and the soil 39 that form the straw 53 are removed, and the one end 3 a of the cylindrical body 3 protrudes from the ground surface 33. Thereafter, the ridges 63 grown inside the cultivation tube 9 can be harvested simply by removing the fresh potato receiving part 7 and the lid part 5 and pulling out the cultivation tube 9 inside the cylindrical body 3. Since the lid 5 covers the one end 3 a of the cylindrical body 3, there is almost no soil inside the cylindrical body 3, so that the cultivation tube 9 is buried in the cultivation soil 51 inside the cylindrical body 3. Therefore, the cultivation tube 9 containing the yam 63 can be easily pulled out from the cylindrical body 3, and can be easily harvested in a short time (see FIG. 14).

  The cylindrical body 3 after pulling out the cultivation tube 9 is used for the next year's mountain cultivation while being buried in the ground 31. One end 3a of the cylindrical body 3 is fitted with the lid 5 so that fallen leaves, soil, etc. infiltrate into the cylindrical body 3 until planting seeds. The inside can be prevented from being buried. As an example, the through hole 13 can be closed by fitting the lid 5 from the one end 3a of the cylindrical body 3 covered with the vinyl sheet 65 or the like, and the fallen leaves into the cylindrical body 3; Infiltration of soil or the like can be further prevented (see FIG. 15).

  When it is time to plant the yam, the lid 5 of the tubular body 3 buried in the ground is removed, and the cultivation tube 9 filled with the above-mentioned soil 39 is inserted into the tubular body 3. Cultivate yam according to the method steps. Since the yam does not cause continuous cropping failure, the tubular body 3 embedded in the ground can be used repeatedly for a plurality of years, and the cost of the yam cultivation apparatus can be reduced. In the seed planting operation, the step of embedding the cylindrical body 3 can be omitted, and the planting operation can be performed in a short time without any effort.
