Description

[Detailed description of the invention] (Field of industrial application) The present invention is a hydroponic cultivation bed in which the amount of culture solution poured into the cultivation path can be adjusted according to the growth conditions of the plants. Regarding.

(Prior Art) Conventionally, as shown in Fig. 1A, for example, as a hydroponic cultivation device, a bed B is placed on supporting legs A ₁ , A ₂ .
, and raise both sides of the width direction upwards as shown in Figure B to form a cultivation path D, place a medium E in this cultivation path D, and pour the culture solution into it to cultivate seedlings F. There is something I did.

(Problem that the invention aims to solve) However, since the conventional bed B has a wide width as shown in Figure 1B and Figure 2, even if you try to reduce the amount of culture solution when the seedlings are small, Unless a considerable amount of culture solution is poured, the liquid level will not be high enough to be absorbed by medium E.

Therefore, even if the seedlings are small, it is necessary to pour a certain amount of culture solution into the water.If you do this, the amount of culture solution will be more than necessary for the growth of the seedlings, and the roots may become rooted due to lack of oxygen, or the culture solution may become too large. The problem was that it was wasted.

Therefore, in this type of device, it is preferable to reduce the amount of culture solution flowing into the cultivation path D when the seedlings F are small, and increase the amount as the plants grow.

(Purpose of the invention) The purpose of the invention is to enable hydroponic cultivation in which the amount of culture solution can be adjusted to the amount that makes it easy for the plants to grow according to the growth condition of the seedlings, and there is no wastage of culture solution, making it easier for roots to spread. The aim is to provide a bed for people to use.

(Means for Solving the Problem) As shown in FIG. 3, the hydroponic cultivation bed of the present invention has two or more cultivation paths 1 with stairs at the bottom 11 of the bed 10 through which the culture solution of the hydroponic cultivation device flows. formed in the shape of
Each cultivation path 1 is formed so that the width of the lower tier is narrower than that of the upper tier, and the depth of the cultivation path 1 of each tier is formed to be constant in the width direction.

(Function) To use the cultivation path 1 of the present invention, for example, as shown in Fig. 3, the planted seedlings F coated with soil E are placed at regular intervals in the narrow central part 3; Pour the culture solution only into the narrow center part 3 of the seedling, and as the seedling grows and becomes larger, let the culture solution flow to the wider outside part 2.

In addition, as another example of use, instead of placing the cultivating soil E directly on the cultivation path 1, a film 8 is spread on the cultivation path 1 as shown in Fig. 2, and planted seedlings F with the cultivating soil E applied thereon are placed at regular intervals. You may also leave it as In this case as well, when the seedlings are small, pour the culture solution only into the narrow center part 3, and as the seedlings grow and become larger, pour the culture solution into the outer part 2.
Allow the culture solution to flow until the In addition, 9 in Figure 2
1 is a wire for supporting the film, and 10 is a clip for fixing the film.

In this case, two or more cultivation paths 1 are formed in the bottom 11 of the bed 10 in a step-like manner, and each cultivation path 1 is formed so that the lower one is narrower than the upper one, so that when the plants are small, If the culture solution is allowed to flow only through the cultivation path 1 on the lower stage and then to the cultivation path 1 on the upper stage as the plants grow larger, it is possible to supply an amount of culture solution suitable for the growth of the plants.

In addition, since the depth of the cultivation path 1 of each tier is formed constant in the width direction, the cultivation path 1 of the lower tier, which has a narrower width,
Even in the case of a V-shaped cultivation path, the width is wider than that of a V-shaped cultivation path, making it easier for plants to spread their roots, making it suitable for plant growth.
Moreover, even if the same amount of culture solution is poured as in a V-shaped cultivation path, the depth of the culture solution will be shallower than in a V-shaped cultivation path, resulting in excess moisture and making it difficult for plants to become rooted.

(Example) FIG. 3 shows an example of the hydroponic cultivation bed of the present invention. Reference numeral 10 in the figure is a bed, which is made of a bed substrate 6 made of metal, plastic, or the like, with a foamed polyethylene sheet or other heat insulating material 7 of about 1 mm thick pasted on top. The material of the bed 10 may be other than that, for example, contrary to the material shown in FIG. good.

At the bottom 11 of this bed 10, two or more cultivation paths 1 are formed in the form of steps. Each cultivation path 1 is formed so that the width of the lower layer is narrower than that of the upper layer. Further, the depth of the cultivation path 1 in each stage is formed to be constant in the width direction.

(Effects) The hydroponic cultivation bed of the present invention has the following effects.

The amount and liquid level of the culture solution flowing into the cultivation path 1 can be easily adjusted according to the growth of the seedlings, and an environment suitable for plant growth can be created.

Moreover, since the depth of the cultivation path 1 of each stage is formed to be constant in the width direction, it becomes easy for plants to spread roots.

Even if the same amount of culture solution is poured as in a V-shaped cultivation path, the depth of the culture solution will be shallower than in a V-shaped cultivation path, making it difficult for plants to become rooted due to excess moisture.

By increasing the number of stages in the cultivation path 1, the amount and level of the liquid can be adjusted more precisely according to the growth of the plants.
