Description

[Detailed explanation of the invention] [Industrial application field] This invention is a method for sowing the seeds of flowers, vegetables, etc. to germinate and
This invention relates to a hydroponic device for plants whose growth status can be observed.

[Conventional technology and its problems]

Conventionally, hydroponic plants have been known in which a seedbed made of foamed synthetic resin is placed in a shallow flower pot, seeds are sown in this seedbed with water soaked in the seedbed, and the germination and growth status can be observed. However, in this conventional hydroponic device, the seedbed is foam-molded from the beginning as a foamed resin mat large enough to fit inside the pot, so the water contained in the seedbed is absorbed by natural evaporation and the hydroponic cultivation of plants ( (Sucking up by seed germination and growth)
Even if the seedbed runs out due to water, the seedbed does not shrink much more than the inner diameter of the pot, and for this reason, it is not possible to check the presence or absence of water in the contracted state of the seedbed, resulting in the problem of the cultivated plants dying due to lack of water. do.

[Means for solving problems]

In order to solve the above-mentioned conventional problems, this invention expands the seedbed greatly to fill the pot with water, and when the water content disappears, it moves away from the inner surface of the peripheral wall of the flowerpot in a direction toward the center. It is characterized by being made of a water-absorbing foamed resin with high expansion and contraction properties that sequentially contracts.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. In the drawing, 1 is a dish-shaped flower pot with a shallow depth, for example, about 10 mm, and the peripheral wall 1a of this flower pot 1 has eight petal shapes. , and a circular concave portion (not shown) depressed from the inner bottom surface of the upper base is provided in the center portion of the inner bottom surface of the pot.

2 is a petal-shaped seedbed set inside this flowerpot 1,
This seedbed 2 expands greatly to fill the pot with water (for example, when it is filled with water, it swells to about twice its size), and when the water content runs out, the inner surface of the peripheral wall 1a of the flowerpot 1 For example, 15mm shrinks sequentially toward the center away from
Water-absorbing foamed resin with a wall thickness of
It is made of FM (trade name manufactured by Achilles) pine.

In the case of this embodiment, the seedbed 2 has a seedbed center portion 2a that fits into the recessed portion of the inner bottom of the pot and expands into contact with the circumferential surface of the recessed portion, and a fitting hole in the seedbed center portion, and the pot peripheral wall 1a. It is formed so that seeds are sown in the center part 2a of the nursery bed which is depressed from the outer part 2b of the nursery bed, and are allowed to germinate and grow as shown in Fig. 2. It may be a seedbed made of a water-absorbing foamed resin in which the part 2a and the outer part 2b are not separated and are integral.

[Effect of idea]

The hydroponic device of this invention has a seedbed 2 made of water-absorbing foamed resin with high expansion and contraction properties as described above in a shallow dish-shaped flower pot 1. The state in which the necessary water is sufficiently contained can be easily determined by observing the state in which the seedbed 2 has expanded greatly to fill one flowerpot as shown in FIG. Contained water is used for natural evaporation and hydroponics of plants (seed germination,
The state where the seedling bed 2 has shrunk and is away from the pot peripheral wall 1a can be easily seen by looking at the state shown in FIG. (The presence or absence of water can be confirmed in the contracted state), so if you replenish the water each time it runs out, you can avoid the problem of the cultivated plants dying due to lack of water.

[Brief explanation of the drawing]

FIG. 1 is a plan view showing a hydroponic device according to an embodiment of the invention in an unused state before water is supplied, and FIG. 2 is a perspective view showing the hydroponic device in a state in which water is being supplied (hydroponic state). 1... Flowerpot, 1a... Pot surrounding wall, 2... Water absorbent foam resin seedbed.
