Description

The present invention relates to a cultivation aid for artificial cultivation of long potatoes, and more specifically, to a drive-in type long-term cultivation aid for planting and harvesting that facilitates planting work and harvesting work without impairing the property of extending directly under long potatoes. is there.

The growth of natural yam (natural potatoes) collected in the mountains is replaced by new potatoes every year while absorbing nutrients from the potatoes, and in spring, a protrusion is formed within 5 cm from the top of the potatoes. Furthermore, from the vicinity of the root of the protrusion, one sprout grows upward again. This sprout absorbs the nutrients of the sweet potato and grows, and the protrusion becomes a sweet potato and the shoot becomes a vine. Along with the growth process, the sweet potato loses its nutrients by the new sweet potato and gradually loses its weight, and eventually it withers and disappears. It is conventionally known that these growth phenomena are repeated in the same manner every year to gradually grow into larger potatoes (natural yams).

The characteristic of natural yam (natural yam) that grows as described above is that it continues to grow deep in the ground, and if there is an obstacle in the middle, it will bend and become a complicated shape, so the surface of the yam is scooped. In order to dig and harvest without damaging it, skilled digging techniques and enormous efforts are required. In addition, it is extremely rare to collect a large amount of natural yam (natural yam) in a limited growth range. In terms of market demand, there are many consumers who prefer high-quality and long-sized natural products, but at present it is not possible to supply enough to meet the demand.

On the other hand, the method of cultivating homemade long potatoes, seed potatoes, in the process of cultivating seedlings such as Reiko, in the field, by using cultivation containers such as pipes and corrugated roofing materials, harvesting work is easy, easy to cook, A cultivation method for producing straight long potatoes has been conventionally known.

As a method for cultivating home-grown potatoes in the above, for example, “long gutter for cultivation” (Patent Document 1) for growing long potatoes into a straight body has been proposed and is a known technique.

The proposal for such "long gutter for cultivation" is to cut both edges of the lower end of a semi-cylindrical synthetic resin gutter into a gap, and to take a little width from the long edges to the gutter above that part. It is a long gutter for cultivation that has small holes all over.

In addition, "guide sheath for natural yam cultivation" (Patent Document 2) is proposed, which enables planting and harvesting work by one person, grows straight, is easy to pack, and is capable of producing sticky and tasty natural yam (Patent Document 2). Has become.

The proposal of such "guide sheath for natural yam cultivation" is to form a sheath main body by providing a brim portion having an arc-shaped cross section on both edges along the longitudinal direction of the half-split pipe, and one end of this sheath main body portion Is spread in the shape of a spoon, and the method of forming the planting part of the seed potato is adopted.

However, these conventional potato cultivation tools in artificial cultivation have a problem that the planting groove having a predetermined depth must be excavated in the soil at the time of burying, and the planting work is complicated. At the same time, as a result, a method of digging a shallow horizontal groove to save the trouble of deeply digging a vertical hole into the soil, and installing a cultivation tool in the horizontal groove in a substantially horizontal direction to cultivate a long potato (Japanese yam) is adopted. It does not take advantage of the nature of natural yams that extend directly underneath, and as a result, long potatoes that are deformed, such as bent, are formed, and sticky, tasty and high quality long potatoes cannot be obtained. There was a problem such as.

The Applicant pays attention to the inherent properties of long potatoes and the problems of conventional devices in artificial cultivation, and cannot provide a device for facilitating planting work and harvesting work without impairing the property of extending directly below when growing long potatoes. Based on the idea of being a product, we have developed a drive-in type cultivation aid for long potatoes that can be embedded in the vertical direction without much effort during cultivation and that can easily harvest the surface of the potatoes without damaging the surface of the potatoes during harvesting. However, the present invention has led to the proposal of the "cultivation aid for long potatoes" in the present invention.

Hereinafter, the embodiment of the cultivation assistance tool 10 for long potatoes in the present invention is described based on a drawing.

In addition, the cultivation aid 10 for long potatoes according to the present invention is not limited to the examples described below, and is within the scope of the technical idea of the present invention, that is, the shape, size, and material capable of exhibiting the same effect. It can be appropriately changed within the range of the above.

FIG. 1 is an explanatory diagram showing an embodiment of a cultivation aid for long potatoes 10 according to the present invention.
The cultivation aid 10 for long potatoes is a driving-in-place type assisting tool used for artificial cultivation of long potatoes, and in terms of shape, the main body 11 has a predetermined length and has a semi-arc shape when viewed from the end. It is formed in the shape of a cylindrical pipe.

As for the material, for example, it is conceivable to use an aluminum member, a copper member, a plated steel member, or the like, in addition to a synthetic resin member such as a vinyl chloride member, but in consideration of weight reduction as well as a hardened type, a hard resin is used. It is preferably made of a component.

A pointed portion 20 having a pointed shape is formed at the tip of the main body 11. The tip 20 has a pointed shape that can be driven into the soil and is formed at the tip of the main body 11. The tip angle of the pointed portion 20 is not particularly limited, but forms an angle of, for example, about 30° to 60° in a side view, thereby forming the pointed portion 20 having a pointed shape that can be driven into the soil. It

A reinforcing portion 22 is formed at the rear end of the main body 11. The reinforcing portion 22 functions as a receiving portion of the striking tool 30 when the main body 11 is driven into the cultivation ground G, and is formed at the rear end portion on the opposite side of the tip portion where the pointed portion 20 is formed. A metal edging piece 21 is fitted on the reinforcing portion 22 in order to withstand the impact of the impact with the impact tool 30. The material of the edging piece 21 is not limited as long as it is made of metal, but is made of, for example, an aluminum member, a copper member, a plated steel member or the like, and is fitted to the rear end portion of the main body 11.

The body 11 has a rear end edge formed with a striking flange 23. The impact receiving flange portion 23 forms a flange portion having a projecting shape such that the rear end edge of the main body 11 is wide and thick, and is hammered into the ground with an impact tool 30 such as a mallet or a hammer. At this time, the main body 11 can be easily and surely driven without being deformed or destroyed.

About the cultivation assistance tool 10 for long potatoes which concerns on this invention which consists of the above structures, it demonstrates the usage mode. FIG. 2: is explanatory drawing which shows the usage method of the cultivation assistance tool 10 for long potatoes which concerns on this invention, (a). Shows the working state at the time of planting, and (b) shows the working state at the time of harvesting.

As shown in FIG. 2( a ), the cultivation aid 10 for long potatoes according to the present invention is in a state where the main body 11 is erected in a substantially vertical direction with the tip 20 facing down with respect to the cultivation ground G at the time of planting. The reinforcing portion 22 is hammered and buried in the soil by hammering the reinforcing portion 22 from above with a hammer 30 such as a mallet. The hitting tool 30 is not particularly limited. It should be noted that it is preferable that the driving is completed so that the rear end of the main body 11 slightly projects from the cultivation ground G, instead of driving so that the entire main body 11 is buried in the soil. As a result, not only the cultivated portion can be visually grasped easily, but also in the tilting operation of the main body 11 which will be described later at the time of harvesting, the protruding rear end portion functions as a finger-holding portion at the time of tilting.

In the state where the main body 11 is embedded in the substantially vertical direction, the seed potato m of the long potato M is planted and cultivated and grown inside the main body 11 having a substantially arc shape. As a result, the potatoes M grow straight in a substantially vertical direction along the main body 11 due to the intrinsic property of the potatoes M extending directly below, and the soil existing in the main body 11 and the inside thereof and the grown potatoes M are integrated. -It will be composed in a lump.

Then, as shown in FIG. 2( b ), at the time of harvesting, the outer peripheral edge of the main body 11 having a substantially arc shape is excavated to a predetermined depth by the excavator 31 such as a double scoop, and a hole is formed in the cultivation ground G. When the body 11 is formed and tilted to the side of the excavated hole, the soil and the potatoes M are tilted together with the body 11 into a single body, that is, the soil and the potatoes M are attached to the inside of the body 11. Both are leaned together in the state. The tilted main body 11 is pulled out from the ground, and then the soil stuck to the inside of the main body 11 is scraped off, whereby the exposed potatoes M are harvested.

As described above, the cultivation aid 10 for long potatoes according to the present invention can be easily embedded and embedded in the soil during cultivation, and can be embedded in a state where it is erected substantially vertically to the cultivation ground G. In addition, it is possible to harvest the potatoes M without any trouble at the time of harvesting and without damaging the surface of the potatoes M, and it contributes to the growth of the potatoes M having a straight shape and good commercial value.

Further, since the impact receiving flange portion 23 protrudes like a protrusion, the main body 11 can be caught and easily grasped, and contributes to the reinforcement of the main body 11 and the resistance to twisting, and the prevention of slippage, and the storability and There are many actions and effects such as improved transportability and ease of pulling out work at the time of harvesting.

The cultivation aid for long potatoes according to the present invention is easy to manufacture and has an advantage in terms of manufacturing cost as well, has excellent durability, and can be repeatedly used, and therefore has no industrial applicability. I think that it is extremely large.
