  The construction of the tall cultivation apparatus 1 of the present embodiment configured as described above will be described below with reference to FIG. When producing the height-cultivating apparatus 1, as shown in FIG. 5 (a), for example, the vertical shafts 2B, 2B... Are set up in parallel with an interval of about 30 cm. It is preferable that there is a horizontal pipe for keeping the distance. In the present embodiment, the two shafts 2 and 2A are installed in a horizontal state. One end 2 of the moisture permeable waterproof sheet 5 in the direction along the shafts 2, 2 </ b> A is wound around one shaft 2 of the two shafts 2, 2 </ b> A installed in parallel and in a horizontal state in this manner. 6a... Are attached at predetermined intervals, and one end of the moisture permeable waterproof sheet 5 along the long side direction is fixed to the shaft 2.

  One end side in the long side direction is loosened in the U-shaped cross section at the other end side of the moisture permeable waterproof sheet 5 fixed to the left shaft 2, while the other shaft 2A has a short side direction (shaft of the moisture permeable waterproof sheet 5) The sheet 5 is fixed to the right shaft 2A with the packers 6a, 6a... In a state in which a middle portion is hooked. Thereby, the moisture-permeable waterproof sheet 5 is suspended and fixed between the shafts 2 and 2A in a slack state with a U-shaped cross section, thereby forming a sheet lower part 5a.

  Then, the cultivation tank 3 is produced. A non-woven fabric 3a is formed into a cylindrical shape, and a culture tank 3 in which a seedling 4 is planted is formed by inserting a medium 3b in which, for example, peat moss and rice husk charcoal are mixed. In addition, the culture medium 3b which comprises the cultivation tank 3 is not restricted to the said thing, What kind of thing may be used as long as a seedling can be planted and grown. The cultivation tank 3 may be prepared in advance before the moisture-permeable waterproof sheet 5 is fixed to the shafts 2 and 2A.

  As shown in FIG. 5 (b), the cultivation tank 3 made in a state of being separated from the moisture-permeable waterproof sheet 5 is positioned on the upper part of the moisture-permeable waterproof sheet 5 that is slung and suspended, The non-woven fabric 3a is wound around the shafts 2 and 2A and fixed using packers 6b, 6b, etc. Thereby, the lower space 7 for ventilation is formed under the cultivation tank 3 supported by the shafts 2, 2 </ b> A, and the lower part of the cultivation tank 3 is surrounded by the sheet lower part 5 a of the moisture permeable waterproof sheet 5. Thereafter, as shown in FIG. 5C, the irrigation tube 10 is placed on the surface of the cultivation tank 3 along the centers of the shafts 2 and 2 </ b> A. One end of the irrigation tube 10 is closed, and the other end is connected with a pump 11 of irrigation means by a hose or the like. In fixing the cultivation tank 3, when the moisture-permeable waterproof sheet 5 is fixed to the shafts 2 and 2A at the same time, the number of use of the packers 6 and the like can be reduced and it is economical. is there.

  Along the irrigation tube 10 placed on the surface of the cultivation tank 3, spacers 9, 9... Made of plastic ridges cut in a short length are placed across the irrigation tube. The distance between the spacers is preferably about 2 m. Then, the free end of the moisture permeable waterproof sheet 5 fixed to the shaft 2A is wound above the cultivation tank 3, surrounded by being separated from the upper part of the cultivation tank 3, and the moisture permeable waterproof sheet 5 is wound around one shaft 2. Secure with packers 6, 6, etc. Thereby, the moisture-permeable waterproof sheet 5 contacts the upper surface of the spacers 9, 9 ..., and the upper space 8 is formed. In this way, the upper space 8 and the lower space 7 can be simultaneously formed on the upper and lower sides of the cultivation tank 3 by using one moisture permeable waterproof sheet 5 so as to surround the cultivation tank 3, so that the sheet material can be used effectively and construction is easy. Therefore, cost reduction can be achieved.

  When planting seedlings 4 such as strawberries, a cross-shaped cut is formed on the nonwoven fabric 3a of the cultivation tank 3 enclosing the culture medium 3b and the moisture-permeable waterproof sheet 5 located on the top, and the cut is opened. The seedling 4 planted in the pot is embedded in the medium 3b. In this way, the seedling 4 is planted in the cultivation tank 3 at a predetermined interval, and the fixed planting operation is completed. Since the moisture-permeable waterproof sheet 5 stretched on the surface shields and shields the heat, the temperature of the surface of the cultivation tank 3 can be prevented from becoming high during the high temperature period, and the seedling 4 can be favorably grown. Moreover, since the moisture-permeable waterproof sheet 5 is excellent also in heat retention and can prevent the rapid change of the temperature of the culture medium 3b in the cultivation tank 3, the seedling 4 can maintain a favorable growth environment.

  When the pump 11 of the irrigation means is operated, the water and the culture solution in the tank 12 are supplied into the irrigation tube 10, irrigated from the upper part of the cultivation tank 3, and the water and the culture solution are supplied to the cultivation tank 3. When the supplied water or culture solution is large, it is dropped through the nonwoven fabric 3a, collected at the sheet lower part 5a of the moisture permeable waterproof sheet 5, collected downstream along the gradient, and collected in the tank 12. The collected surplus water and culture solution are irrigated again to the cultivation tank 3 through the irrigation tube 10 by the pump 11.

  If the air blower 14 which comprises a ventilation means is operated, it will ventilate to the lower space 7 below the cultivation tank 3 comprised with the moisture-permeable waterproof sheet 5 through the ventilation pipe 13. FIG. In the winter period, warm air is supplied through the heating device, and in the summer period, the wind is simply sent, or cold air is supplied through the cooling device. The moisture-permeable waterproof sheet 5 has a certain degree of airtightness, and since one end of the moisture-permeable waterproof sheet 5 on the air outlet side is pasted together to make the opening small, the air volume on the discharge side can be suppressed, and the sheet 5 swells like a duct, and the wind spreads uniformly throughout the cultivation tank 3. For this reason, cold air or warm air is appropriately circulated in the culture medium 3b in the cultivation tank 3, and the growth of the seedling 4 can be suitably controlled. By the blowing means, a specific gas such as oxygen can be blown into the moisture-permeable waterproof sheet 5 according to the purpose. The specific gas is supplied from the cylinder 15 and blown into the lower space 7 by the blower 14.

  When water or a culture solution is supplied through the irrigation tube 10, the non-woven fabric 3a constituting the cultivation tank 3 is always wet by irrigation, and the water contained in the non-woven fabric 3a is forced by being ventilated by the blowing means. The medium 3b in the cultivation tank 3 can be cooled. By stretching in a state where the moisture permeable waterproof sheet 5 is wound around the cultivation tank 3, air is sent to the entire culture medium 3 b in the cultivation tank by increasing the blowing efficiency, so that the culture medium 3 b can be cooled uniformly. A large number of seedlings 4 can be uniformly grown.

  For example, the time when the average temperature in a facility such as a greenhouse exceeds 20 ° C. is used as a guide for air blowing, and air is blown for about 12 hours per day. When the air is being blown, it is necessary to irrigate the water to evaporate (vaporize) so that the nonwoven fabric 3a wrapping the culture medium 3b of the cultivation tank 3 does not dry. Due to such a watering effect, for example, in the summer of 2007 when it was extremely hot, especially in September after planting, the temperature of the medium in the daytime cultivation tank could be lowered by an average of 3 to 5 ° C. It was also effective in mitigating and securing the harvest within the year. Thus, the advantage of medium cooling using heat of vaporization is that it can be introduced at low cost.

  In the elevated cultivation apparatus 1 constructed in this way, the seedlings 4 such as strawberries planted in the culture medium 3b of the cultivation tank 3 grow using water or a culture solution supplied from the irrigation tube 10 to the culture medium 3b as nutrients. . When a large amount of water or culture solution is supplied, the excess solution is dropped through the nonwoven fabric 3a, so that it is possible to prevent supply of excessive moisture and culture solution. Excess liquid is collected and collected at one end by the gradient of the moisture permeable waterproof sheet 5. Then, the recovered surplus liquid is circulated again without being discarded and is irrigated to the cultivation tank 3 through the irrigation tube 10. Moreover, by sending air to the lower space 7, the air in the moisture permeable waterproof sheet 5 flows without stagnation, the wind spreads uniformly in the cultivation tank 3, and the seedlings can be grown uniformly.

  For mulching work to cover the ground around the plant, the moisture permeable waterproof sheet 5 is used to enclose the cultivation tank 3 before planting the seedling 4, so that the plant body is not damaged during planting, and the top surface of the medium and the plant periphery No algae, no fly, etc., and a clean environment can be maintained. In addition, even when planted at high temperatures, the upper surface of the medium and the ground of the plant body do not become hot due to light shielding properties, heat shielding properties, and moisture permeability, and in the case of strawberries, it has an effect on delayed flower bud differentiation and root growth inhibition. There is an effect that it is not necessary to consider. In addition to the multi-function, it is possible to send wind (cold air or warm air) or carbon dioxide gas to the upper space 8 and the lower space 7 provided on the upper surfaces of the moisture permeable waterproof sheet 5 and the cultivation tank 3, and the strawberries. It is also possible to achieve the effect that the growth of the seedling 4 such as can be controlled more finely.

  In the above-described embodiment, the air pipe 13 that constitutes the air blowing means is connected to the lower space 7 and is configured to send cold air, hot air, or a specific gas only to the lower space 7. Alternatively, the blower pipe 13 from the blower 14 may be branched so as to blow air to the upper space 8. Moreover, you may comprise so that different gas may be sent to upper and lower space by dividing the air blower which ventilates to upper space, and the air blower which ventilates to lower space. In this way, by processing the blower pipe or separately using the blown gas, for example, by blowing carbon dioxide into the upper space 8 above the cultivation tank 3 constituted by the moisture permeable waterproof sheet 5, strawberries or the like are blown. The growth of seedlings can be promoted.

  Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various designs can be made without departing from the spirit of the present invention described in the claims. It can be changed. For example, the slack of the moisture permeable waterproof sheet is adjusted so that the slack is applied to the lower part of the moisture permeable waterproof sheet, and the liquid flows from the upstream part where the slack is small to the downstream part where the slack is large. May be kept constant, and the two shafts supporting this sheet may be inclined to form a gradient.

  An example of a cylindrical packer with a slit was shown as a packer for fixing a cultivation tank or a moisture permeable waterproof sheet to two shafts, but other shapes may be used, and non-woven fabrics and sheets may be fixed. If possible, it is not limited to a packer.

  As an example of use of the present invention, by using this elevated cultivation apparatus, crops other than strawberries, for example fruit berries such as tomatoes that are often cultivated with the cultivation tank isolated from the ground, or leaves such as spinach and leaf lettuce It is suitable for high-altitude cultivation where cultivating moss can be performed and a person can easily harvest crops while standing.
