Description

[Detailed Description of the Invention] The present invention relates to a bed for hydroponic cultivation, and particularly to a bed that can be used for both the cultivation of fruit vegetables and leafy vegetables.

In recent years, hydroponic cultivation has been widely adopted, and its cultivation techniques are improving year by year. is the current situation. For example, fruit vegetables such as tomatoes, cucumbers, and melons
Using the RW (Rotsuku Wool) method, leafy vegetables such as green onions, honeysuckle, and saladana are processed using NFT (culture medium thin film).
They are cultivated using different methods.

However, the hydroponic beds are different between cultivation using the RW method and cultivation using the NFT method. Therefore, in order to cultivate both fruit vegetables and leaf vegetables, there was a problem in that beds for both types had to be prepared separately.

The present invention was made in view of the above-mentioned conventional problems, and the purpose is to provide a hydroponic bed that can be used for both the cultivation of fruit vegetables using the RW method and the cultivation of leafy vegetables using the NFT method. .

The hydroponic cultivation bed according to the present invention is provided with a plurality of partition walls, a required number of culture solution flow passages are formed along the longitudinal direction at the bottom between the partition walls, and the upper part of the culture solution flow passage is used for cultivating leafy vegetables. A planting board support step is formed to support the planting board, and a base support step is formed above the planting board support step to support a rock wool base for cultivating fruits and vegetables.

EMBODIMENT OF THE INVENTION Hereinafter, with reference to FIG. 1 and FIG. 2, the embodiment of the hydroponic cultivation bed according to the present invention will be described in detail.

In each drawing, reference number 1 is a bed for hydroponic cultivation made of styrofoam. In this bed 1, three partition walls 2, 3, and 4 are formed along the longitudinal direction at equal intervals in the width direction. Also, between the partition walls 2 and 3 and between the partition walls 3,
Two flow passages 5 and 6 are formed along the longitudinal direction at the bottom of the space between the two passageways 4 to allow the culture solution 30 to flow therethrough. Each of these flow passages 5 and 6 has a support groove 7 and 8 that supports a temperature control pipe 20 at the center of the bottom, as shown in FIG.
have.

On both sides of the upper part of each of the above-mentioned flow passages 5 and 6, there are planting boards 2.
Planting board support stepped portions 9 and 10 that support both lower surfaces of 1
and 11 and 12 are formed facing each other. The planting board 21 is used when cultivating leafy vegetables using the NFT method, and is usually made of styrofoam. The planting board 21 is formed into an elongated shape with a width that engages with the opposing planting board support steps 9, 10 and 11, 12, and has planting holes for planting leafy vegetable seedlings 31. A large number of 22 are arranged at appropriate intervals in the longitudinal direction.

Furthermore, the planting board support step portions 9, 10, 11,
Above the base 12 is a base 2 as shown in FIG.
Base support steps 13 and 14 are formed to support 3. The base support step portions 13 and 14 are formed between the partition walls 2, 3, and 4 and the planting board support step portions 9 and 12 adjacent to these partition walls 2, 3, and 4. It is designed to support the lower surfaces on both sides. Further, a protrusion 15 is formed between the planting board support step portions 10 and 11, and this protrusion 15 is at the same height as the base support step portions 13 and 14.
It is configured to support the central lower surface of No. 3.

The base 23 is used when cultivating fruits and vegetables using the RW method, and is made of rock wool.
It is formed into an elongated shape with a width that engages with 4. A planting bed 24 made of rock wool and having a cylindrical shape is placed on the base 23. This planting bed 24 has a circular hole 24a formed in its center, and a cylindrical holding body 25 made of rock wool is removably inserted into the hole 24a. This clamping body 25 is divided into two parts in the vertical direction so that the seeds of fruits and vegetables can be
A clamping portion 25a is formed for clamping. Further, a required number of engagement grooves 16 are formed along the longitudinal direction on the lower surface of the bed 1, and these engagement grooves 16 are adapted to engage with pipes 27 constituting the bed support 26, respectively. ing. Further, an engaging portion 17 is formed at one end of the bed 1 to engage with the other end of another bed 1 having the same configuration.
An engaged portion 18 is formed at the other end, with which one end of another bed 1 having the same structure is engaged. Therefore, a large number of beds 1 can be connected in the longitudinal direction and used. In addition, reference number 28,
29 is a vinyl sheet.

Next, a method for carrying out hydroponic cultivation using the above-mentioned bed 1 will be explained.

First, the bed 1 is placed on the bed support base 26 with each engagement groove 16 aligned with the pipe 27. Similarly, other beds 1 are sequentially placed on the bed support base 26, and the engaging portions 17 and engaged portions 18 of each adjacent bed 1 are engaged and integrated. A temperature control pipe 20 is installed at each support groove 7, 8 position.

Therefore, when cultivating fruits and vegetables using the RW method, after covering the partition walls 2 to 3 with a wide vinyl sheet 28 as shown on the left side of FIG. A base 23 is installed on the protrusion 15. Next, after the seeds 32 of fruits and vegetables are clamped by the clamping portions 25a of the clamping bodies 25, the clamping bodies 25 are respectively inserted into the through holes 24a of the planting bed 24. Then, each planting bed 24 into which the clamping body 25 has been inserted is placed on the base 23, and the culture solution 30 is caused to flow into the flow paths 5 and 6. As a result, the culture solution is transferred to the base 23 and the planting bed 2.
4. Seeds 32 are supplied through the clamping body 25, and the seeds 32 root and germinate to cultivate fruits and vegetables.

On the other hand, when cultivating leafy vegetables using the NFT method, as shown on the right side of FIG. Support step portion 10,1
A planting board 21 is installed on top of the planting board 1. Then, seedlings 3 of leafy vegetables that have taken root and germinated in the planting hole 22 of each planting board 21 are placed.
1, culture solution 30 is placed in the flow channels 5 and 6.
inflow. As a result, the nutrients in the culture solution 30 are directly absorbed from the roots, and the seedlings 31 grow.

Pipe 20 for both RW method and NFT method above
Temperature control can be performed by flowing hot water, cold water, etc. into the tank.

In the embodiment shown in FIG. 2 above, the RW method is used between the partition walls 2 and 3, and the RW method is used between the partition walls 3 and 4.
An example of using it as an NFT method is shown, but
It is also possible to use both the space between the partition walls 2 and 3 and the space between the partition walls 3 and 4 as the RW method or the NFT method.

In addition, three partition walls have been installed to support RW and NFT systems.
Although both methods have shown examples in which four-row planting is possible, the number of partition walls may be any number as long as it is two or more. Furthermore, although the number of flow passages between the pair of partition walls is two in the example, it may be one or three or more.

As mentioned above, the hydroponic cultivation bed according to the present invention is provided with a plurality of partition walls, and a required number of culture solution flow passages are formed along the longitudinal direction at the bottom between the partition walls. A planting support step for supporting a planting board for cultivating leafy vegetables is formed on the upper part, and a base support step for supporting a rock wool base for cultivating fruit vegetables is further formed above the planting board support step. It is the composition. Therefore, it is possible to cultivate fruit vegetables using the RW method and leaf vegetables using the NFT method, which is extremely economical and efficient. In addition, since it is appropriately partitioned by partition walls, it has great practical value, such as being able to prevent the transfer of pathogenic bacteria as much as possible.
