Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a hydroponic culture medium used for cultivating vegetables and flowers in a home hydroponic cultivation device or the like.

Conventional technology Conventional hydroponic cultivation media include foamed polyurethane blocks 11 with notches 12 as shown in Figures 3 and 4, Rockwool Prots, Ri, 1:3, etc. .

In the polyurethane foam block 11 shown in FIG. 3, seeds are placed in the notch 12 in the center, and the polyurethane foam block 11 absorbs water and germinates.
In the rock wool block 13 shown in the figure, the hole 1 provided in the center
4. Place the seeds in the container and let them absorb water and germinate.

Problems to be Solved by the Invention However, the conventional hydroponic culture media mentioned above were all made of a single material such as foamed polyurethane or rock wool, and were composed of many hydrophilic materials. The surrounding area was extremely humid. Therefore, there was no problem with seeds that are resistant to excessive humidity such as tomatoes, cucumbers, and komatsuna, but when used on seeds that dislike excessive humidity such as Horen grass, the germination rate was extremely low.

An object of the present invention is to improve the drawbacks of the conventional hydroponic culture medium described above, and to provide a hydroponic culture medium that does not cause a decrease in germination rate even when used for seeds subject to excessive humidity.

Means for Solving the Problems In order to achieve the above object, the hydroponic culture medium according to the present invention has the following features:
A layer of hydrophilic material such as rock wool is provided at the bottom, and a layer of hydrophobic material is provided above, which is made of a material such as foamed polyethylene, and has a cut vertically penetrating in the center.

How it works: Put the seeds of lotus grass etc. into the cut in the upper layer of hydrophobic material such as foamed polyethylene, and place between the upper layer of hydrophobic material such as foamed polyethylene and the lower layer of hydrophilic material such as rock wool. When the seed is soaked in water, the lower side of the seed is supplied with a suitable amount of moisture by the lower hydrophilic material layer, and the upper side of the seed is unlikely to become over-humidified because the upper hydrophobic material layer absorbs water. Therefore, even seeds that dislike excessive humidity, such as Horenso, can be germinated without problems.

In addition, when seeds germinate, the emerging buds have to push out the walls of the notch in the upper hydrophobic material layer in order to elongate, resulting in very large seedlings. Subsequent growth will be ensured.

Example An embodiment thereof will be described below with reference to FIGS. 1 and 2.

In the figure, a culture medium 1 is constructed by covering the upper and outer periphery of a layer 2 of a hydrophilic material such as rock wool with a layer 3 of a hydrophobic material made of a material such as foamed polyethylene. In the center of this hydrophobic material layer 3, there is a notch 4 that penetrates in the vertical direction.

Seeds 5 are inserted through the notches 4 of the hydrophobic material layer 3,
It is set between the hydrophilic material layer 2 and the hydrophobic material layer 3.

The hydrophilic material layer 2 absorbs moisture from below and supplies an appropriate amount of moisture to the seeds 5, and the hydrophobic material layer 3 utilizes its hydrophobicity to prevent the seeds 6 from becoming overly moist. Therefore, even seeds that dislike excessive humidity, such as Horenshin, can be reliably germinated. Moreover, since the sprouts that emerge from the germination of the seeds 5 need to push out the walls of the notches 4 in the hydrophobic material layer 3 and grow outward, strong seedlings are inevitably produced.

Effects of the Invention As described above, the hydroponic cultivation medium according to the present invention is composed of a hydrophilic material layer and a hydrophobic material layer, and the seeds are set in the middle part thereof, so that over-humidification of the seeds is prevented. Even seeds that dislike excessive humidity, such as Horenkei, can be reliably germinated, and the germinated seeds will push out the wall of the cut made in the hydrophobic material layer and extend their buds, so This has the great effect of making the seedlings durable.
