DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cultivation tool for a yam, such as a yam or a geninjo, which uses tubers cultivated in a mountain field or an embankment, and a cultivation method thereof.

[0002]

2. Description of the Related Art Conventionally, the cultivation method of yam has been cultivation of how to maintain the natural original shape of potatoes and grow them as thick as possible. . For this reason, it was natural that the deformed potato, such as the branch and the dumpling, was generated in the potato section due to the influence of nematodes and soil. In recent years, tub-shaped or plate-shaped seats having a large number of through holes are buried in the ground diagonally in the ground, and grown on them to grow according to the seats. In some cases, yams are grown in a polygonal cross-section tube composed of a cover and a lid, or a specific yam storage bag is obliquely buried in soil.

Also, as disclosed in Japanese Patent Application Laid-Open No. 2-171116, after a yam is stored together with soil in a specific storage bag, the storage bag is soaked in soil so that the cross section of the storage bag becomes substantially candle flame-like. A cultivation container and a cultivation method for obtaining a yam having a high commercial value, a circular cross section and a substantially linear shape in the longitudinal direction by cultivating the potato in an inclined manner and cultivating the potato are known.

[0004]

However, in the conventional example, it is difficult to grow the potatoes straight with zunguri so as to have commercial value, and therefore, the characteristics of the yam and the improvement of the cultivation method have to be improved. During the process, how to remove the elongated or branched potatoes, how to be straight, with the potatoes growing in Yamano while keeping the meat quality white and high quality, and the taste and detail are not different from those of Yamano Efforts were made to make them fat. In addition, since the whole potato part directly or indirectly touches the fertile soil of the field, there are many things that are harmful due to the influence of parasites such as nematodes and fertilizer nutrients.

Further, in the apparatus disclosed in Japanese Patent Application Laid-Open No. Hei 2-171116, it is necessary to bury the storage bag in the soil so that the storage bag has a substantially candle-like cross section.
For this reason, there is a problem that much labor is required for the cultivation work of yam, and the work efficiency is reduced.

The present invention has been made in view of the above-mentioned problems, and eliminates the conventional elongated potatoes or branched potatoes, has a white and high-quality meat, and has a commercial value while maintaining the same taste and fineness as those of Yamano. To produce the maximum potato diameter of the yam, which is more slick than before, and to completely grow it from the soil with nematodes and fertilizer due to the characteristics of the potato, and the effects of fertile soil, etc. The purpose of the present invention is to prevent malformation caused by cultivation, and to improve the working efficiency by reducing the cultivation labor.

[0007]

Means for Solving the Problems To achieve the above-mentioned object, according to the present invention, there is provided an instrument for cultivating a lower potato portion of a yam buried in a fill, which is buried in the fill and having an opening at an upper portion. A substantially cylindrical potato cultivation container having,
The potato cultivation container is provided so as to be able to descend in a space portion thereof, and is provided with a funnel-shaped middle receiving member having water permeability substantially at the bottom center, and the middle receiving member is arranged below the potato portion. .

A donut disk-shaped center stabilizing plate is provided on the bottom of the center receiving member for holding and regulating the vertical position of the center receiving member in the space inside the embankment during descent.
Inserted into the protruding neck at the bottom of the intermediate receiving member formed in the shape
Or it shall be composed, can be made which arranged permeable member having a recess in the bottom substantially central. Further, in a peripheral contact portion inscribed in a space portion in the embankment of the middle receiving member,
A plurality of cuts or projections may be provided to alleviate the descent sliding friction, or a plurality of drainage holes may be formed in a side wall surface in the potato cultivation container, or an upper portion of the potato cultivation container The inner diameter portion may be configured to be thin to delay the initial descent of the middle receiving member, or may be provided with a detachable tubular connector. In addition, the potato cultivation container that is in contact with the outer periphery of the middle receiving member may have an appropriate cut portion for imparting a descent resistance of the middle receiving member.

Further, the cultivation method of the present invention is a method for cultivating a lower potato portion of a yam in a substantially cylindrical pot portion cultivation container buried in an embankment and having an opening at an upper portion, wherein the potato portion cultivation container is provided. The lower potato portion is enlarged and extended above the middle receiving member which can descend in the space portion, and while being subjected to speed limitation depending on the pressing force on the middle receiving member due to this enlargement and expansion, the lower potato portion passes through the embankment. It is characterized by being cultivated by descending.

[0010] In the cultivation tool and method for cultivating yam according to the present invention, the space inside the embankment is lowered while pushing down the middle receiving member in a state where the tip of the potato portion is crushed as the yam grows. As it grows, it can be stretched downward while maintaining its thickness, generating a thick and straight maximum potato diameter unique to yam with no branching potato. Moreover, the space portion in the embankment provided with the drainage trough function makes it possible to prevent the whole potato portion from directly contacting the fertile soil of the field, thereby preventing harm caused by parasites such as nematodes. Furthermore, by assembling the completed inner receiving member into a connector, and arranging a plurality of the connectors and burying them all at once, cultivation can be performed without any labor, and the working efficiency can be improved.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. In the cultivation container of the present embodiment, the cultivation device 1 serving as the main body of the cultivation container partitions the inside of the embankment forming the cultivation space for the enlargement and expansion of the new potato, as shown in FIGS. 1 and 2. The cultivator 1 has a bottle-shaped pot cultivation container 2 having a drain opening 2A at a lower portion and a drain hole 2B on a side surface, and a connection inserted into an upper open end of the pot cultivation container 2. Vessel 3 and potato cultivation container 2
The inside of the funnel tub-shaped middle receiving member 5 that can be pushed down and moved with an arbitrary descending frictional resistance against the pressing force based on the enlargement and extension of the potato portion, so that red clay does not overflow from the middle receiving member 5 during movement. And a frame 7 for holding the paper portion 6 stretched over the upper opening end of the connector 3.

The center receiving member 5 has a donut disk-shaped center stabilizing plate 8 for holding and regulating the vertical position of the center receiving member 5 in the potato cultivation container 2 which is a space portion in the embankment during the descent. Is detachably fitted into the protruding neck-shaped bottom opening 5A. Further, a permeable member having air permeability and a concave portion formed on the upper surface, for example, a gypsum member, a synthetic resin such as a porous rubber, etc., is provided in the protruding neck-shaped bottom opening 5A of the middle receiving member 5. A tip receiver 9 made of a member such as a member or a sponge is fitted. The bottom opening 5A is closed with a lid 10 having a plurality of drain holes 10A formed in the bottom surface. A plurality of vertical cuts 5B are provided in a peripheral contact portion of the middle receiving member 5 which is inscribed in the potato cultivation container 2 so as to reduce sliding friction.

As shown in FIG. 6, instead of fitting the distal end receiver 9 to the intermediate receiving member 5, the entire intermediate receiving member 5 is formed by a permeable member, and the central curved concave portion is integrally formed. You may. For example, it can be formed in a square shape (see FIG. 6), which is a piston Owan shape, and a shell type (see FIG. 7), which is a piston Owan shape. Although not shown, it may be formed in a semicircular shape of a piston Owan shape, a square shape of a piston dish shape, a semicircle or shell shape of a piston dish shape, or a vinyl cylinder shape.

A plurality of semicircular or rod-shaped protrusions 5 for reducing the sliding friction in place of the cuts 5B are provided on the peripheral contacting portion of the middle receiving member 5 which inscribes the potato cultivation container 2.
C may be attached (see FIG. 4).

As a method of fitting the potato cultivation container 2 to the lower part of the connector 3, a method of fitting the connector 3 to the outer periphery and the inside of the connector 3 by a detachable fitting type and a screw type is considered.

Further, by setting the height of the connector 3 and the height of the middle receiving member 5 to be approximately the same, the middle receiving member 5 is fitted into the connecting device 3, and a plurality of the connecting devices 3 are arranged and soiled at once. Work can be performed to improve work efficiency.

The pot cultivation container 2 to be brought into contact with the outer periphery of the middle receiving member may have an appropriate cut portion 2C for imparting resistance to drop of the middle receiving member 5. Specifically, as shown in FIG. 8, the cut portion 2C forms one vertical cut portion in the middle receiving member 5 having a large diameter with respect to the inner diameter of the potato cultivation container 2. The cut portion 2C may be formed in a spiral shape of approximately 180 degrees or less, as shown in FIG. 9, which may be opened with a slight gap or slightly overlapped.

The cultivator 1 is composed of a synthetic resin member which is light in weight and easy to assemble, or a member made of ceramic, light metal or the like having permeability or water permeability or not, and a drain hole is provided on a side surface thereof. Having 2B,
Alternatively, the inner receiving member 5 may be provided with a plurality of drain holes 4 on the peripheral wall surface or may be omitted.

Next, a method of assembling the cultivator 1 in the present embodiment will be described. First, as shown in FIG. 1, the front end support 9 is fitted into the middle receiving member 5, and the center stabilizing plate 8 is inserted into the protruding neck-shaped bottom opening 5 </ b> A of the middle receiving member 5. The board 8 is fixed. Next, the middle receiving member 5 is fitted into the connector 3, the inside of the middle receiving member 5 is filled with red clay, covered with the paper portion 6, and fixed so that the paper portion 6 is sandwiched by the frame 7. Then, the potato cultivation container 2 is fitted into the lower portion of the connector 3 to obtain a completed cultivator 1 (see FIG. 2).

Next, a method of using the cultivator 1 in the present embodiment will be described. As shown in FIG. 2, fine red soil of a known sterile and non-fertilizer used for cultivation of Ginenjo is slightly and strongly packed in the middle receiving member 5. The soil is not put in the potato cultivation container 2, that is, it is left in an empty state, and the middle receiving member 5 is fitted into the potato cultivation container 2 to obtain a completed cultivation device. Then, the entire potato cultivation container 2 is covered with newsprint paper 6 or the like and stopped with a rubber band 12 so that red soil does not overflow (see FIG. 5).

After the field has been disinfected and fertilized, the cultivator 1
Width and length L of the potato cultivation container 2 corresponding to the width and height of
1. Dig a groove on the embankment at an interval L2 between cultivators in adjacent rows. For example, as shown in FIG. 3 (a), if the field soil is hung about 20 cm above the frame 7 of the cultivation device 1, there is no problem in drainage, and if the ridges can be made without difficulty, it is shallower than the height of the cultivation device 1. May be. The frame 7 of the cultivator 1 and the middle receiving member 5 are arranged in this groove without any gap in a vertical line. Then, FIG.
As shown in the figure, by the time the seed potatoes and the cut potato seedlings are planted, the chopsticks 11 such as bamboo of about 20 cm are vertically set on the center of the middle receiving member 5 so that the whole is filled with the soil of the field. Make ridges by burying the soil. Finally, as shown in FIG. 3 (c), the seeds of the seed potatoes and the cut potatoes are planted so that the new chopsticks enter the holes by pulling out the disposable chopsticks 11.

In the current cultivator 1, the total weight of the yam is 6
The target is around 00g. At this time, the width diameter D of the potato cultivation container 2 is preferably approximately φ10 cm, and the length L1 is preferably approximately 20 cm. In other words, if the total weight is exceeded, the potato portion will be significantly deformed inside the potato portion cultivation container 2, but it can sufficiently cope by adjusting the capacity and length of the potato portion cultivation container 2 to the target weight.

In the cultivator 1, the odd or even number is a seed potato,
We will use it for cutting potato seedlings and the other for mukago so that it will be a seed potato next year. When only the seed potatoes and the cut potato seedlings are used, the cultivators 1 are arranged in a row so as to be empty. Fertilization management refers to the cultivation method of Jinenjo. At the time of planting, it is necessary to pull out the chopsticks and carefully set the germination point of the seed potato so that the new potato can pass through the hole.

The potato cultivation container 2 may be omitted as long as the potato cultivation space for growing the new potatoes partitions the embankment while limiting the descending speed of the potato as a growth space. Of course. For example, instead of the cultivation space, an elastic member such as a loofah, which is a descent resistance member, may be interposed, or the soil may be laminated by sequentially changing the types of soil having different flexibility.

Further, in order to pursue an ideal zung-ri potato, when the position of the target potato is low with the above resistance value, the middle receiving member 5 comes into contact with the bottom of the potato cultivation container 2 earlier than expected. The degree to which the receiving member 5 is in contact with the bottom of the potato cultivation container 2 is long,
Since the tip of the potato part may be flattened and the commercial value may be impaired, as an improvement of the above-mentioned cultivation equipment, in order to delay the initial descent of the middle receiving member 5, a few cm of the upper part of the potato part cultivation container 2 is required. It is also possible to reduce the inner diameter and increase the drop resistance value of the middle receiving member 5 (including a detachable connector).

The above-described cultivation method using the cultivator 1 is characterized in that the amount of red soil only needs to enter the middle receiving member 5, and the potato can be grown to a deep gung by making the original maximum potato diameter. In other words, the potato portion extends straight down while enlarging at the center of the middle receiving member 5, and the middle receiving member 5 is placed in the potato cultivation container 2.
Press down inside. At this time, an ideal potato can be obtained by balancing the enlargement and elongation and the drop resistance value of the middle receiving member 5.

The cultivator 1 may be shorter than the yam cultivator of the prior art, so that the depth of the hole may be smaller than before. Then, the cultivators 1 are simply arranged vertically without considering the inclination angle of the cultivators 1 at the time of embedding as in the prior art. For example, a method of forming and inserting a vertical hole as a possibility of mechanization may be considered.

Furthermore, since the potatoes inside the potato cultivation container 2 do not directly contact the soil, parasites such as nematodes are hardly observed. In other words, the fine roots of the potatoes extend through the drainage hole of the potato cultivation container 2 to the field soil with nematodes, but the nematodes have reached the potatoes and do not damage the potatoes. And we can improve the shipping rate,
Even though the potato portion is slightly bent, the potatoes are less prominent than before, and the potato skin condition is good.

[0029]

According to the cultivation tool and the cultivation method of the yam according to the present invention, as the lower potato grows in the middle receiving member, the lower potato grows while pushing down the embankment and moving. Since the swelling is restricted and the swelling is restricted, it is possible to obtain the thick and straight maximum potato diameter peculiar to the yam without branching potato. In other words, the elongated potatoes or branch potatoes found in the yam cultivation according to the prior art are eliminated, the meat quality is white and high quality, the taste and the fineness are the same as those of Yamano, while the zunguri and straight potatoes with commercial value are straight Can be cultivated. In addition, since the potato portion expands and expands in the middle receiving member, the potato portion does not touch the soil of the field, and it is possible to prevent harm due to malformation and parasitic infestation such as nematodes. Furthermore, it is possible to improve the working efficiency by reducing the cultivated培労force.
