First Embodiment A supply set 1 according to the present embodiment includes a container 2 filled with water for supplying plants, and first and second pipes 3 and 4 communicating with the inside of the container 2. Are provided.

One end of the first pipe 3 opens into the container 2 through the connection piece 10 at the mouth 2 a of the container 2 (the lower part of the container shown in FIG. 1). The end is open as a watering hole.

One end of the second pipe 4 is connected through the upper part of the container (see FIG. 1) and opens into the container 2, and the other end is provided with a moisture detector 5 having high water absorbency. Have been.

A water-absorbing coating 6 is provided so as to surround the end of the first pipe 3 that functions as a water sprinkling hole and the end of the second pipe 4 where the moisture detector 5 is provided. ing .

As the moisture detector 5, for example, a member made of a large number of beads made of ceramic (unglazed) or polyethylene, or a member provided with many minute gaps and pores such as felt is used. The second pipe 4 is communicated with the outside (that is, the soil accommodated in the flowerpot) via the moisture detector 5 and the covering 6. Further, the free ends of the first pipe 3 and the second pipe 4 are set so as to be close to each other by the covering body 6. The cover 6 is preferably made of, for example, a sponge having open cells. The cover 6 has a function of appropriately adjusting the amount of water in the container 2 to be supplied to the soil and a function of preventing the moisture detector 5 from being clogged.

The flower pot applied to the supply set 1 of the present invention is not limited to a specific one. For example, anything that is sold at a horticultural store, such as a flower pot made of unglazed or synthetic resin, a metal flower pot, or a planter made of synthetic resin, that can function as a flower pot can be used.

As the container 2 for supplying water, a discarded container such as a PET bottle can be appropriately used.

The soil for potting is not limited to a specific soil. For example, soil mixed with mulch or Kanuma soil is preferable from the viewpoint of easy availability and easy care.

The first and second pipes 3, 4 are preferably soft tubes having a diameter of 5 to 6 mm, for example, made of vinyl chloride, polyethylene (PE), polypropylene (PP), silicone, natural or synthetic rubber. Adopted.

The cross-sectional area of the first and second pipes 3 and 4 is preferably 1 to 3 mm ² .

As shown in FIG. 1, if the upper part of the container 2 communicates with the outside air, the pressure in the upper space R of the container 2 and the pressure in the second pipe 4 are substantially equal to the atmospheric pressure. The water in 2 flows out into the soil via the sprinkling hole of the first pipe 3 and the covering.

On the other hand, if a predetermined amount of water exists in the soil and the covering 6, the water in the soil enters the minute gaps and pores of the water detector 5 by capillary action. For this reason, the minute gaps and pores of the moisture detector 5 are closed by the water, and the communication between the upper space R of the container 2 and the second pipe 4 and the outside air is prevented. At this time, the water in the container 2 acts as a kind of piston and tends to go down. For this reason, the pressure in the upper space R of the container 2 and the pressure in the second pipe 4 becomes 1 atm or less. When the pressure in the second pipe 4 decreases, water in the soil is drawn into the second pipe 4 as droplets in minute gaps and pores of the moisture detector 5. At this time, the minute gaps and pores of the moisture detector 5 are closed by water, and the communication between the upper space R of the container 2 and the second pipe 4 and the outside air is blocked.

Therefore, the water in the container 2 does not descend, and no water is supplied to the soil from the free end of the first pipe 3.

Embodiment 2 The configuration of a supply set according to the present embodiment is different from the supply set according to Embodiment 1 in that first and second pipes 3 and 4 are provided in a connection piece 10. Different (see FIG. 2).

With such a configuration, there is an advantage that a step of forming a hole in the bottom of the container 2 is not required.
