[Problems to be Solved by the Invention] In recent years, there has been an increasing demand for greening. And, as living spaces become smaller and smaller, there is a growing desire to grow plants in even the smallest places, seeking a little more moisture and comfort. Potted plants are widely used as a way to enjoy green at any place, because it takes up relatively little space than before. However, this pot plant has a limited water retention capacity for the fixed medium used, so flowers and plants may die if water is not sprayed every day or every two days from early summer to autumn. I couldn't be away for a long time. Moreover, even if it did not wither, the growth would worsen, possibly affecting the growth from the following year. On the other hand, in the winter season, the water in the potted plant is easily frozen, which sometimes causes the plant to wither.

As an alternative to pot planting, there is hydroponic cultivation. In this hydroponic cultivation, the plant is cultivated in a state in which the roots of the plant are immersed in the nutrient solution, so that it is only necessary to appropriately replenish the water or the nutrient solution. There is an advantage that there is no worry even if you are away for a long time. However, in this hydroponic cultivation, since the roots are always in water, there were problems such as root rot, poor growth, susceptibility to disease, and poor yield.

The inventors of the present invention have conducted intensive studies to solve these problems, and as a result, have arrived at the present invention.

The outer periphery of the plant cultivation container 12 is provided with one or a plurality of holes 34 for cultivation inducing pillars to attract vines when the plant 24 is a vine or the like. Alternatively, it is used to stand uprights for supporting upward growth. In this case, it is preferable to arrange the rope or the rod-shaped member so as to straddle between the columns erected in the two or more cultivation inducing column holes 34.

Further, by using the holes 34 for the cultivation inducing pillars, for example, as shown in FIG.
The tunnel 40 for greenhouse cultivation can be configured by erected 6 on each of two opposite sides of the plant cultivation container 12 and covering the support 36 with a resin sheet 38. By configuring the tunnel 40 for greenhouse cultivation, even in the winter season, it is possible to grow the plant 24 without bringing the plant cultivation apparatus 10 into a room or the like,
It is convenient. In addition, the tunnel 40 for greenhouse cultivation can also be constituted by crossing a curved column in the diagonal direction of the plant cultivation container 12 to be erected, and furthermore, linear columns are respectively erected at four corners. Such a method is also possible, and the method is not particularly limited.

The fixed culture medium 14 accommodated in the culture medium accommodating section 26 of the plant cultivation container 12 has one or a plurality of concave portions 44 for accommodating the seedling raising plugs 42. The recess 44 is preferably formed integrally when the fixed medium 14 is molded. For example, as shown in FIG. 4, a groove 46 is formed, and a block 48 made of the same material as the fixed medium 14 is formed in the groove 46. May be arranged at appropriate intervals to form the recessed portion 44. With this configuration, the interval between the recessed portions 44 can be arbitrarily set depending on the arrangement of the blocks 48, and the plants 24 can be grown at appropriate intervals according to the type of the plants 24 and the like.

The fixed medium 14 is preferably a solidified medium containing fibrous components as a main raw material. Particularly, the fixed medium 14 is made of wood fibers as a main raw material, and may be made of rock wool, nonwoven fabric, cotton, felt or other fibrous materials. It is also preferable to harden the mixture by further mixing the components and further the earth and sand as appropriate. The fixed medium contains compost, solid fertilizer, inorganic and
When organic and chemical fertilizers are contained, the main component of the nutrient solution is water, but when the fixed medium itself does not contain fertilizers, fertilizer components that contribute to plant growth are contained in the nutrient solution. The nutrient solution is supplied. Here, the solid phase ratio represented by the ratio of the solid phase volume to the medium volume is 10 to 9
0% is preferable, 20 to 70% is more preferable, and 30 to 50% is more preferable. The gas phase ratio represented by the ratio of the air volume to the medium volume is about 20 to 30%.

Here, in particular, as the wood fiber, a fiber obtained by mixing cypress bark and cedar bark at a predetermined ratio is preferable, and such a wood fiber is used as a main raw material, for example, rock wool, resin fiber or other fibers. A mixture of tree chips and bark fibers is used. The fibers consisting of hinoki bark and cedar bark are processed so as not to damage the active ingredients such as hinokitiol originally possessed by hinoki and cedar, and were planted in a fixed medium 14 using, for example, the antibacterial action of hinokitiol. The disease of the plant 24 is prevented, and at the same time, pests and the like attached to the plant 24 can be eliminated. Therefore, the space 3 of the plant cultivation container 12
Insects may not be generated in the nutrient solution 16 in the nutrient solution storage unit 28 or in the fixed medium 14, or the insects may not come to the plant 24 planted, so that the plant 24 becomes sick or eaten by pests. Is less. It is preferable that the fixed medium 14 mainly composed of the hinoki bark and the cedar bark is covered and fixed by a binder made of resin or the like or resin fibers so as not to be dispersed. The fixed medium 14 having such a configuration is excellent in water retention, air permeability, water storage, and heat retention as compared with an artificial fixed medium such as ordinary soil or rock wool, and the thickness of the fixed medium 14 is reduced. It does not hinder the growth of plants such as fruits and vegetables.

The fixed medium 14 may be composed of one composition as a whole as shown in FIG. 1. For example, the fixed medium 14 is divided into a lower fixed medium 50 and an upper fixed medium 52 as shown in FIG. It is also possible to configure. When the fixed medium 14 is divided and configured, the lower fixed medium 50 is preferably set to have a fiber component configuration (composition) so that the plant 24 is suitable for growing with roots. Also,
The upper fixed medium 52 is provided with a plurality of through-holes 54, and is configured to form the recessed portion 44 in combination with the lower fixed medium 50. It is preferable that the upper fixed medium 52 is not intended to grow the roots of the plant 24, and that the composition of the fiber component is set so as to suppress the lower fixed medium 50 so as to stabilize and retain water.

Next, the seedling raising plug 42 germinates the plant 24 from a seed at a predetermined place and grows the plant 24 to a predetermined size, and then places the plant 24 together with the seedling raising plug 42 in the recess 44 formed in the fixed medium 14. They will be inserted and raised. Therefore, the seedling raising plug 42 may be any material that is suitable for germinating the plant 24 or growing the plant 24 to a predetermined size after transplanting, and thereafter transplanting the plant 24. Although it may be composed of an acidic component, it may be composed of a foamed resin such as foamed polyurethane, and is not particularly limited.

The nutrient solution 16 stored in the nutrient solution storage unit 28 of the plant cultivation container 12 is composed of water or a liquid fertilizer comprising water and a fertilizer.

The liquid level is controlled by moving up and down within a substantially constant range of the water level difference.

Here, as shown in FIG. 1, the liquid level control means 22 is a PET bottle or other bottle-like container 56.
And an on-off valve 60 attached to a cap 58 for closing the inlet of the container 56. After the nutrient solution 16 is placed in the container 56, the cap 58 is closed and the container 56 is closed.
Is turned over in the air, the nutrient solution 16 does not flow out because the on-off valve 60 is closed. Next, the liquid level control unit 22 is set upright on the nutrient solution storage unit 28 in an inverted state, and the open / close valve 60 is brought into contact with the bottom surface of the nutrient solution storage unit 28 and is pushed up to open. When the on-off valve 60 is opened, the nutrient solution 16 flows out and air flows into the container 56. However, when the on-off valve 60 is closed by the outflowing nutrient solution 16, the inside and outside of the opening bottom of the on-off valve 60 are opened. When the pressures are balanced, the outflow of the nutrient solution 16 will stop. Therefore, the nutrient solution storage unit 2
When the nutrient solution 16 in the tank 8 decreases and the liquid level drops, a pressure difference is generated between the inside and outside of the container 56, and the nutrient solution 16 flows out from the inside of the container 56 until it is balanced, so that the liquid level is controlled. .

The bottle-shaped container 56 is not limited to a cylindrical shape, and a shape having a large capacity such as a rectangular cross section is preferably selected. Further, the entire container 56 may be transparent, but it is preferable that at least a part of the container 56 is transparent so that the remaining amount of the nutrient solution 16 can be seen from the outside. Others
It is also possible to attach a liquid level gauge to the container 56, and conversely, it is also possible to configure the container 56 so that the remaining amount is not displayed as well as the liquid level meter, and there is no particular limitation.

The nutrient solution 16 stored in the nutrient solution storage unit 28 of the plant cultivation container 12 is supplied by the nutrient solution supply means 18.
From the nutrient solution storage unit 28 using the liquid level difference
4 is supplied. The nutrient solution supply means 18 is, for example, a long fiber or a capillary tube aligned in one direction to form a bundle, or a non-woven fabric or the like, and uses the capillary phenomenon to suck up the nutrient solution 16 in the nutrient solution storage unit 28, and It is preferable to supply water to the upper surface of the fixed medium 14 having a low water content. The nutrient solution supply means 18 can be used as long as the material is excellent in water absorption. In this way, by irrigating the fixed medium 14 from the top surface, the plant 2 planted in the fixed medium 14
Because water and fertilizers are not directly applied to plant 4, plants such as vegetables 2
The four leaves and fruits are not discolored.

Further, as shown in FIG.
It is also possible to arrange the end of the fixed medium 14 on the side of the fixed medium 14 at the bottom of the fixed medium 14 and to irrigate the bottom of the fixed medium 14. Further, although not shown, the fixation medium 1
It is also possible to configure so as to irrigate from both upper and lower surfaces of No. 4, and there is no particular limitation. The same effect can be obtained with any configuration.

Here, the nutrient solution supply means 18 and 62 provide a height difference between the fixed culture medium 14 side and the nutrient solution storage section 28 side, so that the nutrient solution 16 is sucked up and supplied by utilizing the capillary phenomenon. Therefore, one end of the nutrient solution supply means 18 or 62 is pulled up, or a part of the nutrient solution supply means 18 or 62 is shut off using a pinch cock or the like, and the nutrient solution is supplied. Preferably, the supply of 16 is stopped.

Further, the nutrient solution supply means may be configured to supply the nutrient solution by utilizing only the water absorbing force due to the capillary phenomenon. In this case, the height of the contact point between the nutrient solution supply means and the fixed medium is set to be substantially the same as or slightly higher than the height of the nutrient solution in the nutrient solution storage unit, and a sufficient water absorbing power can be secured. It is necessary to set the material and composition of the nutrient solution supply means. According to such a nutrient solution supply means, when the fixed medium is dried, the nutrient solution supply means absorbs the nutrient solution at any time and supplies it to the fixed medium, and when the fixed medium becomes wet, the supply of the nutrient solution is stopped. Will do.

Next, the upper part of the plant cultivation container 12 is
The lid 20 is open at least at the place where the plant 24 grows. By covering the plant cultivation container 12 with the lid 20, it is possible to prevent the nutrient solution 16 from evaporating from the nutrient solution storage part 28 and the location of the fixed medium 14, and furthermore, pests and the like enter the plant cultivation container 12. Can be prevented. Also, this lid 2
0 is formed of an opaque material, so that the nutrient solution storage unit 2
8 and the fixed culture medium 14 can prevent the occurrence of water bloom and the like. Further, by forming the lid 20 with a foam, the inside of the plant cultivation container 12 is insulated against direct sunlight or the like, so that the temperature of the fixed medium 14 and the roots of the plant 24 can be prevented from rising too much. it can.

At 0, the plant 24 will be grown. When the nutrient solution 16 is absorbed or the nutrient solution 16 evaporates as the plant 24 grows, the nutrient solution 16 is supplied to the fixed medium 14 by the nutrient solution supply means 18, and the liquid level control means 22 and the nutrient solution storage The nutrient solution 16 is supplied as needed until all the nutrient solution 16 in the section 28 is exhausted. Therefore, it is not necessary to supply water and fertilize every day, and the plant 24 does not wither even if it is left for a few weeks. Further, the nutrient solution 16 supplied to the fixed medium 14 is left in the container 56 of the liquid level control means 22 or the nutrient solution storage unit 28, and is at the same temperature as the outside air temperature or the temperature of the fixed medium 14. Therefore, there is no influence caused by the temperature difference of the fertilizer. Further, the nutrient solution 16 contains the fixed medium 14.
The nutrient solution 16 is not attached to the leaves or fruits of the plant 24 and is not discolored or deteriorated.

Since the liquid phase ratio of the fixed medium 14 used in the plant cultivation apparatus 10 is more preferably set to 30 to 50%, the plant 24 does not rot, and the growth of the plant 24 is not affected. It rarely gets sick, and fruit crops do not decrease their yield. In this plant cultivation apparatus 10, the cultivation conditions such as the supply of the nutrient solution 16 and the temperature control are stable, so that the crops of plants such as fruit vegetables and flowers are expected to be almost like farmers.
