Abstract

<P>PROBLEM TO BE SOLVED: To provide a method for cultivating a yam (Dioscorea batatas), capable of growing the yam to be straight and well-shaped, and capable of harvesting the yam in a complete form without being damaged when harvested. <P>SOLUTION: This method for cultivating the yam comprises using a long tube having a length corresponding to that of the yam, forming many holes for penetrating water on a side surface of the long tube, burying the tube in the ground of a plowed field, and planting the yam therein. Thus, the yam is straightly cultivated, because it is grown in inside of the tube, and further is pulled out from the ground together with the tube, when it is harvested. Therefore, the yam is harvested without being damaged. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for cultivating a yam called a natural potato that is delicious as a bounty of a mountain.
[0002]
[Prior art]
Conventionally, wild potatoes, which are called natural potatoes, grow naturally in the forest, and it takes patience and labor to find and dig out the thin, long and easily breakable potatoes as they are.
[0003]
[Problems to be solved by the invention]
However, these potatoes have recently been cultivated and produced by hand in fields, and are generally called yam because of their shape, and they can be seen in various sizes, but they are generally 80 cm in length. And the thickness is around 6 to 8 cm.
[0004]
Therefore, when harvesting, potatoes that are deeply buried in the soil will not be able to sell for sale when they are excavated, or will grow straight if there are obstacles such as stones in the field. There was a dislike that the product value was reduced.
[0005]
[Means for Solving the Problems]
The inventor has conducted intensive research in view of this point, and as a result, by using a cylindrical long tube by utilizing the property that the yam grows straight, cultivating the yam in this long tube, the potato is It grew straight in a long cylinder, and a yam with excellent commercial value was obtained.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is an explanatory view of a long cylinder (1) buried in a field soil, having a length of about 90 cm and a diameter of about 6 to 8 cm. It is suitable, and a material made of vinyl chloride is suitable as a material that is hardly oxidized in the soil, but this material is not specified. On the side surface of the long cylinder (1), a number of small holes (2) for water permeability are provided.
[0007]
FIG. 2 shows an embodiment in which the long tube (1) is embedded in the field soil and the seed potato (3) is planted on the upper surface of the long tube. FIG. 3 is a state diagram of the harvest period in which the yam A grew in the long tube (1). In this way, the long tube was dug out of the field soil G to obtain the sweet potato A.
[0008]
【Example】
A hole is drilled on the produced ridge, and a long cylinder (1) having a length of 90 cm and a diameter of 7 cm shown in FIG. 1 is embedded in the hole. The long tube (1) is made of PVC, and has a water-permeable hole (2) on the side surface over the entire length of the tube. Then, the long tube (1) is filled with field soil and the seed potato (3) is buried on the upper surface, and the planting as shown in FIG. 2 is completed. Although the long cylinder is made horizontal in the drawing for drawing, it is naturally used vertically.
[0009]
Some fertilization and weeding are performed on the way, but the potatoes cultivated after about 4 months have grown sufficiently in the buried long tube (1) as shown in FIG.
[0010]
Harvesting uses a special excavator. The excavator excavates the long tube (1) together with the long tube (1) from the soil and pulls out the yam A from the long tube (1). This yam A grows straight and elongated by the oval tube (1) and is put on the market as a product having high commercial value.
[0011]
【The invention's effect】
As described above, the method for cultivating the yam of the present invention uses a long tube, and grows the yam in the tube. The yam grown by the method is a straight potato with a good shape and a high commercial value, and has an epoch-making action effect that the potato is excavated at the time of harvesting so that the potato is not damaged.
[Brief description of the drawings]
FIG. 1 is an explanatory diagram of a long cylinder. FIG. 2 is a diagram of an embodiment of burying. FIG. 3 is a diagram of an embodiment of a harvesting period.

Claims (1)

A long tube (1) provided with a large number of water-permeable holes (2) on the side surface is drilled and buried in the field soil. A potato cultivation method characterized by planting, waiting for the growth of potato A, excavating a long tube (1), and harvesting the straight potato A.
