Description

[Detailed description of the invention] <Industrial application field> The present invention relates to equipment used for hydroponic cultivation, and in particular, it is capable of storing the required amount of culture solution, and is capable of directly immersing the culture solution into the roots of cultivated plants. Concerning unitized equipment that cannot be used.

<Prior Art> In hydroponic cultivation, it is necessary to supply a culture solution to cultivated plants, and in order to avoid the need for constant supply, a liquid storage section is provided.

However, if the roots of plants are left directly immersed in the liquid reservoir, root rot may occur due to lack of oxygen, or overnutrition may occur due to the application of excessive culture solution, which is not favorable for plant growth.

<Objective> In order to eliminate such drawbacks, the present invention aims to provide unitized equipment for use in hydroponic cultivation.

<Structure> The present invention consists of a water-retaining member having an arbitrary size and thickness, and a water-permeable member that covers the entire outer surface of the water-retaining member and does not allow the roots of cultivated plants to penetrate. equipment.”

<Example> The present invention will be explained below based on the example shown in the drawings.

FIG. 1 shows hydroponic cultivation equipment 1,
Reference numeral 2 denotes a water-retaining member, which is shaped like a rectangular parallelepiped and has an arbitrary size and thickness. This water-retaining member 2 is made of water-absorbing rock wool as an inorganic fiber material.
It is made of glass wool, a cellulose-based material as an organic fiber material, water-absorbing urethane foam as a foamable synthetic resin, charcoal, sand, etc., and may be in a mat shape as shown in the figure or in a block shape. In addition, when forming with charcoal, sand, etc., a shape retaining material is required.

Reference numeral 3 denotes a water-permeable member, which covers the entire outer surface of the water-retaining member 2 and is composed of a non-woven sheet-like material made of non-woven fibers such as polyvinyl alcohol, polyester, nylon, etc. It shall have minute pores that roots cannot pass through.
It is preferable that the pores have a diameter of 50 μm or less, for example.

The second example uses such hydroponic cultivation equipment.
As shown in the figure.

A bed base member 4 has an inclined surface in a direction substantially perpendicular to the longitudinal direction of the bed.

Reference numeral 5 denotes a liquid supply means disposed above near the high edge of the bed base member 4, which is provided with a plurality of through holes 5a for discharging the culture solution into the tube body, and at least the plants on the bed base member. The structure is such that the culture solution can be supplied to the part where the roots are placed.

Reference numeral 6 denotes a liquid collection means disposed below the lower edge of the bed base member 4. This liquid collection means 6 is formed in the shape of a gutter as shown in the figure, and is formed to receive the culture liquid flowing on the bed base member 4 and to flow it into a specific liquid tank.

Then, the hydroponic cultivation equipment 1 is placed on the bed base member 4, and the water-retaining medium 7 is placed on the hydroponic cultivation equipment 1. The water-retentive medium may be omitted.

8 is a covering member that supports the cultivated plants 9 and prevents temperature changes in the culture solution due to solar heat, etc.;
Alternatively, it is made of a material with good heat insulation and light shielding properties in order to prevent the generation of chlorella due to light irradiation.

The necessary amount of the culture solution supplied by the liquid supply means 5 passes through the water-permeable member 3 and is absorbed and retained in the water-retaining medium 2, and the excess culture solution flows on the bed base member 4 to collect the liquid. It is collected by means 6.

Therefore, even if the supply of culture solution from the solution supply means 5 is stopped, the necessary amount of culture solution is retained in the water-retaining member 2, so there is no need to constantly supply the culture solution, and supply due to power outages, etc. Can respond to liquid problems.

Moreover, if a liquid storage part for the culture solution is provided on the lower surface of the hydroponic cultivation equipment 1 (not shown) and the water permeable member 3 on the lower surface is brought into contact with the liquid storage part, the water permeable member 3 on the lower surface
Since the culture solution is supplied to the water-retaining member 2 by passing through, there is no need to provide a solution supply means.

Furthermore, even if the roots extend and protrude from the water-retaining medium 7 as the plant grows, they are blocked by the water-permeable member 3 and cannot pass through it. Plant roots do not invade 2, and the hydroponic cultivation equipment 1 can be used repeatedly.

In addition, the water permeable member 3 on the lower surface of the hydroponic cultivation equipment 1
Even when the roots of the plant are in contact with the culture solution storage part, the roots of the plants are not directly immersed in the culture solution, and problems caused by excessive nutrition do not occur. Since the roots of the plants and the water-retaining medium are not in direct contact with the culture medium at all times due to the interposition of the water-permeable member 3, they can absorb appropriate oxygen, so that no adverse effects due to lack of oxygen occur.

Another embodiment is shown in FIG. In this embodiment, a recess 21 is provided on the upper surface of the water retaining member 2, and the water permeable member 3 covers the water retaining member 2 along the shape of the recess 21.

If it has such a shape, when the water-retaining medium 7 is placed on the hydroponic cultivation equipment 1 as shown in FIG. Stabilize.

Furthermore, as shown in FIG.
may be covered with a water-permeable member 3, and a plurality of hydroponic cultivation equipment 1 shown in FIG. 1 may be arranged in series.

FIG. 5 shows another example of how the hydroponic cultivation equipment 1 is used.

What is shown in FIG. 5a is a hydroponic cultivation equipment 1 whose entire outer surface is covered with a net 11, and the net 11 can prevent deformation.

The one shown in FIG. 5b is one in which the lower half of the hydroponic cultivation equipment 1 is covered with a watertight film 12, and since the film 12 serves as a simple tray as a tray for the culture solution, the tray and bed base can be Member 4 etc. are unnecessary.

In the device shown in FIG. 5c, the upper half of the hydroponic cultivation equipment 1 is covered with a net 11, and the lower half is covered with a watertight film 12. As in the case of FIG. 5b, the tray becomes a simple tray as a tray for the culture solution, so there is no need for a tray, bed base member 4, etc.

<Effects> The present invention has the above configuration and has the following effects.

(1) If the equipment of the present invention is used for hydroponic cultivation, the water-retaining member will store the necessary amount of culture solution, and the water-permeable member coated on the top surface of the water-retaining member will absorb the roots of the cultivated plants. Since the water-permeable member coated on the lower surface of the water-retaining member prevents the water-retaining member from being immersed in the culture solution, effective hydroponic cultivation can be performed.

(2) Since the water-retaining member and the water-permeable member are combined into a unit, it can be easily placed and used in a hydroponic cultivation bed, etc., and labor-saving installation work can be achieved.

(3) Since the entire outer periphery of the water-retaining member is covered with a water-permeable member, deformation can be prevented and transport is easy.

(4) Since the plant roots are blocked by the water-permeable member and do not invade the water-retentive member, the device of the present invention can be used repeatedly.
