Description

[Detailed description of the invention] [Field of application of the invention] The invention relates to a hydroponic culture medium used for hydroponic cultivation, and is particularly suitable for creating good cultivation conditions when germinating or raising seedlings. This invention relates to a culture bed for hydroponic cultivation.

[Background of the idea]

As shown in FIGS. 1 and 2, conventional culture beds for hydroponic cultivation include a culture bed 1 made of open-cell foam.
A notch 2 was provided in the. At the time of sowing, the seeds were placed in the notches 2 after the culture bed 1 had sufficiently absorbed water. Furthermore, in some cases, the upper surface of the seeds was covered with a thin hygroscopic paper to prevent the seeds from drying out. However, in the cultivation bed 1, if the seeds are too dry or covered with thin paper, the seeds may become overhumidified and problems such as an insufficient amount of light irradiation may occur. Ta. In addition, ventilation around the seeds also had a negative effect, requiring extremely complex management to maintain a good germination environment and improve the germination rate, as well as to obtain well-grown seedlings. Therefore, it takes a lot of effort to obtain a large number of well-growing seedlings using the conventional culture bed 1, and it cannot be used when producing large quantities of vegetables by hydroponic cultivation. The drawback was that I couldn't do it.

[Purpose of invention]

In view of the above points, it is an object of the present invention to provide a hydroponic cultivation bed that can maintain an optimal environment during germination and seedling raising, and that has a simple configuration.

[Summary of the idea]

Adequate light and moisture are often required for successful germination of sown seeds. However,
Seeds will rot if soaked in water, so careful management is required. Therefore, the present invention focused on the fact that hygroscopic fibers are effective in obtaining good germination conditions, and by adjusting the density of the fibers and the contact condition between the seeds and the fibers, the sown seeds are It is characterized by being able to obtain an optimal environment.

[Example of idea]

Hereinafter, an embodiment of the hydroponic culture bed according to the present invention will be described in detail with reference to FIGS. 3 to 8. FIG. 3 is a plan view of the culture bed, and FIG. 4 is a side view of FIG. 3. In the figure, a large number of highly hygroscopic fibers 12 are arranged above a culture bed 11 made of open-cell foam, and cuts 13 are provided in the culture bed 11.

Next, the state in which the seeds are seeded on the culture bed will be explained with reference to FIGS. 5 to 8. 5 and 6 are a plan view and a sectional view showing a state in which small seeds are sown, and FIGS. 7 and 8 are a plan view and a sectional view showing a state in which large seeds are sown.
In the same figure, in the case of small seeds 14, fiber 1
In the case of a large seed 15, the fiber 12
I'm riding on top of it. However, since the fibers 12 absorb moisture, it is possible to apply appropriate moisture to the seeds 14 and 15. Furthermore, since the light beam can be applied from above, it is also possible to sufficiently irradiate the light beam.

Next, other embodiments of the culture bed according to the present invention will be described with reference to FIGS. 9 to 14. FIG. 9 and FIG. 10 are a plan view and a side view showing a configuration in which fibers are bent and arranged, and in the same figure,
A hygroscopic fiber 22 bent above a culture bed 21 made of open-cell foam is placed so as to be implanted in the culture bed 21, and a cut 23 is made in the culture bed 21. It has a set configuration. According to such a configuration, seeds or young seedlings are not damaged by the fibers 22.

FIG. 11 and FIG. 12 are a plan view and a side view showing a configuration in which the fibers above the culture bed are lengthened and arranged densely. In the figure, hygroscopic fibers 32 are densely arranged upward from the inside of a culture bed 31 made of open-cell foam, and cuts 33 are provided in the culture bed 31. The seeds 34 are the fibers 32
It can be held in a state sandwiched between the walls and provide appropriate moisture and light.

FIGS. 13 and 14 are a plan view and a side view showing a configuration in which fibers are arranged more densely than in the previous embodiment. In the figure, hygroscopic fibers 42 are arranged very densely in a foam 41, and seeds 44 are sown by pushing them into the fibers 42. This configuration is suitable for germinating and growing seeds that require more moisture than the above embodiments.

As explained in the above embodiments, suitable conditions can be provided to various seeds by changing the density when arranging the hygroscopic fibers or the length of the fibers.

According to these configurations, it is possible to germinate or raise seedlings by optimally maintaining sunlight and humidity using the fibers in the sown part of the culture bed, making it easier to manage seedlings and at the same time, producing seedlings with good growth. It will be done.

[Effect of idea]

As explained above, according to the present invention, it is possible to expose seeds to sufficient light and maintain and provide a high humidity environment, which allows for good germination and seedling raising, and the production of a large number of well-growing seedlings. can.
