Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventionally, there were the following problems. After cultivating natural sweet potatoes in a pipe, water and water flow pressure were required for harvesting without damaging the natural sweet potatoes and the pipe. This invention was made to solve the above problems.

Means for Solving the Problems

[0005] A sheet 3 that is hollow and wound in layers is provided on the upper side of a container 2 for cultivating natural sweet potatoes 8. Cultivation soil 7 is put into the container 2 and the sheet 3, and a heat insulating material 4 is attached to the outside of the sheet 3. A ring 5 for fixing the sheet 3 and the heat insulating material 4 and a support column 6 for holding the sheet 3 filled with the cultivation soil 7 are provided. This invention is a method for cultivating and harvesting natural sweet potatoes having the above configuration.

Effects of the Invention

[0006] Natural sweet potatoes can be cultivated in a container provided on the ground, and harvested by removing the sheet. Harvesting does not require water, water flow pressure, or digging up the soil, nor does it require carefully removing the surrounding soil to match the length and shape of the yam. In this invention, the length of the yam to be cultivated can be freely selected by increasing or decreasing the height of the sheet and support poles. The number of yams to be cultivated can be freely set by arbitrarily selecting the length of the sheet and the diameter and number of times the sheet is wrapped. By attaching insulating material, the temperature rise of the cultivation soil can be suppressed even in places that are exposed to direct sunlight for long periods of time. The thickness and number of support stakes can be freely selected according to the amount of growing soil. [Brief explanation of the drawing]

[0007] [Figure 1] This is a cross-sectional view of the present invention. [Figure 2] This is an external view showing the usage state of the present invention. [Modes for carrying out the invention]

[0008] The following describes embodiments for carrying out the present invention. A sheet 3, rolled up in a hollow space, is placed on top of the container 2, and support posts 6 are erected on the outside of the sheet 3. Place the growing soil 7 into the sheet 3 and container 2, and attach the insulating material 4 to the outside of the sheet 3. The insulation material 4 is fixed to the support column 6 by attaching the ring 5 from the outside. The present invention has the structure described above. Harvesting the wild yam 8 cultivated using the present invention involves removing the ring 5, heat-retaining material 4, support pole 6, and sheet 3, and then removing the cultivation soil 7 to harvest the wild yam 8.
