  The present invention relates to a fruit and vegetable cultivation apparatus in which a solid medium formed in a substantially inverted V-shaped cross section is arranged in a longitudinal direction on a cultivation bed, a related fruit and vegetable cultivation method, and the like. Further, for example, a substantially plate-shaped solid medium member formed by inflating and forming vermiculite is disposed in a gable roof shape, thereby forming a solid medium having a substantially inverted V-shaped cross section. The present invention relates to a fruit vegetable cultivation apparatus in which a solid medium is arranged in a longitudinal direction on a cultivation bed, a related fruit vegetable cultivation method, and the like.

  In contrast to outdoor cultivation where crops are cultivated under natural weather conditions, greenhouse cultivation in greenhouses and greenhouses is widely used. In house cultivation, there are advantages such as stable production with little influence of the weather, and adjustment of harvest and shipping time.

  In the facility of the cultivation facility, soil cultivation, nutrient solution culture, nutrient solution cultivation, and the like are performed according to the type of crop. Soil cultivation is a method of fertilizing cultivated soil within a facility to grow crops, similar to outdoor cultivation. On the other hand, hydroponics is a method in which soil is put in a cultivation bed, irrigation and fertilization are performed with the nutrient solution, and farm products are grown. Hydroponic cultivation is a method for growing crops by irrigating and fertilizing with a nutrient solution without using soil in the cultivation bed.

  Among these, hydroponics is classified into hydroponics that does not use a medium, solid medium cultivation that uses a medium, and the like.

  Hydroponics is a method of cultivating with nutrient solution without using soil or solid medium. On the other hand, the solid medium cultivation is a method of cultivating with a nutrient solution using a solid medium as a root support instead of soil. In general, rock wool or the like is used as the solid medium.

  Most crops, including fruit vegetables, can be cultivated on the ground. However, from the viewpoints of productivity and economy, there are many agricultural crops that are actually adopted as one of the main production methods.

  For example, in the case of strawberries, tomatoes, etc., hydroponic soil cultivation in the cultivation facility is widely used. A gantry is built in the cultivation facility, and a cultivation bed is installed on it (high cultivation). The soil is put in the cultivation bed, and seedlings are transplanted and cultivated. In addition, hydroponics and solid medium culture using rock wool as a solid medium are also performed.

  In general, if the same material is continuously used without exchanging the soil / medium, the soil / medium deteriorates and the productivity of the crop is impaired. Therefore, it is necessary to periodically change the soil and culture medium, and the work load has been large.

  Then, this invention aims at providing the new cultivation means of the crop etc. which can improve yield and quality, and can reduce the work burden by soil exchange etc.

  This inventor tried cultivation of fruit vegetables using the solid medium which is lightweight and has moderate water retention and air permeability. As a result, we have obtained the knowledge that we can harvest almost the same yield and quality as the conventional method.

  Therefore, in the present invention, by applying this knowledge, a fruit and vegetable cultivation apparatus in which a solid medium formed in a substantially inverted V-shaped cross section is arranged on the cultivation bed in the longitudinal direction and a similar fruit and vegetable cultivation method are provided. To do.

As described above, even when fruits and vegetables are cultivated in a solid medium, the yield and quality equivalent to those of the conventional method can be maintained, so that the crop yield can be improved as a whole. In addition, by tilting the medium, it is possible to prevent fruit vegetables from being damaged, and to improve the quality of the harvest.

  In addition, in the present invention, since a solid medium is used, soil replacement is not necessary, and since a light solid medium is used, medium replacement is also easy. Therefore, work load such as soil exchange and medium exchange can be greatly reduced.

  If the bottom of the medium is configured to be flat, water stays in the pores at the bottom of the medium due to the balance between capillary force and gravity, impeding air permeability, resulting in reduced root vitality and Prone to corruption. On the other hand, by forming the solid culture medium in a substantially inverted V-shaped cross section, the water supplied to the top of the culture medium moves to the bottom of the culture medium, and a region where no water stays can be secured at the top of the culture medium. Thereby, the area | region which has air permeability can be hold | maintained in a solid culture medium, and root decay can be suppressed.

  By forming the solid medium in a substantially inverted V-shaped cross section, an inner space is formed between the cultivation bed and the solid medium. You may make it the structure which installs the air supply pipe for temperature control in this site | part. Thereby, compared with the conventional method which installs the piping for warm / cold water and controls temperature, the temperature control equipment of a culture medium can be simplified and cost-reduced.

  In addition, in this fruit vegetable cultivation means, as above-mentioned, since the air permeability in a culture medium is hold | maintained by forming a solid culture medium in a substantially inverted V-shaped cross section, hot air or cold air is supplied to this inner space part. As a result, the entire medium can be heated and cooled uniformly and rapidly.

  In addition, a solid medium having an appropriate water retention capacity is used, and is provided with irrigation means extending in the longitudinal direction and irrigating the solid medium from above, and an immersion sheet member covering the top of the solid medium and its vicinity. By doing, irrigation can be performed efficiently and generation | occurrence | production of an excess culture solution can be suppressed.

  As described above, by adopting the fruit and vegetable cultivation means according to the present invention, it is possible to improve the yield and quality of the fruit and vegetable in the facility cultivation and the like, and to reduce the work burden due to soil exchange and the like. In addition, since the configuration is simple and lightweight, the installation and introduction work can be performed easily and at low cost. Furthermore, management and maintenance can be performed easily and at low cost by the simplification and cost reduction of the temperature control equipment and the efficiency of irrigation, and the environmental load can be reduced.

<About the fruit and vegetable cultivation apparatus which concerns on this invention>
The fruit and vegetable cultivation apparatus according to the present invention includes all those having at least a configuration in which a solid medium formed in a substantially inverted V-shaped cross section is arranged on the cultivation bed in the longitudinal direction. Hereinafter, description will be made with reference to FIGS.

  FIG. 1 is a schematic external perspective view showing an example of a fruit and vegetable cultivation apparatus according to the present invention, and FIG. 2 is a schematic cross-sectional view thereof.

  In the fruit and vegetable cultivation apparatus A of FIG. 1 or FIG. 2, the cultivation bed 2 having a substantially U-shaped cross section installed on the gantry 1 assembled with the leg member 11 and the support member 12, and provided on the cultivation bed in the longitudinal direction. The drainage groove 21, the solid medium 3 disposed in the longitudinal direction on the cultivation bed 2 and formed in a substantially inverted V-shaped cross section, and the irrigation means extending in the longitudinal direction and irrigating the solid medium 3 from above 41, a submerged sheet member 42 covering the top of the solid medium 3 and the vicinity thereof, and an air supply pipe 5 for temperature adjustment provided in the inner space 51 formed between the cultivation bed 2 and the solid medium 3. And a plant 6 transplanted in the planting hole 32 formed on the inclined surface of the solid medium 3.

  The gantry 1 is a pedestal that supports the cultivation bed 2. For example, by assembling the gantry 1 so that it is easy to work, installing the cultivation bed 2 on it, and carrying out high cultivation, the work burden is compared with the case of working at the height of the ground. It can alleviate and prevent damage caused by some pests.

  The gantry 1 can be assembled by a known material and method based on the purpose, the shape of the cultivation bed 2 and the like. For example, a rod-shaped member such as a synthetic resin pipe or steel pipe may be used as the leg member 11 and the support member 12 and appropriately fixed with a connecting member or the like.

  The cultivation bed 2 is a portion that becomes a bed (floor) when cultivating plants. In this invention, in order to arrange | position the solid culture medium 3 on the cultivation bed 2, what was formed in the cross-sectional substantially U shape is preferable. Known materials can be used, and the material and the like are not particularly limited. For example, foamed plastic such as foamed polystyrene is light in weight, excellent in heat insulation, inexpensive, shock-absorbing, and suitable for easy molding. .

  In this invention, since it uses the solid culture medium formed in light and substantially reverse V shape, it is not necessary to put a culture medium in the whole cultivation bed. Further, since the air supply pipe 5 for temperature adjustment can be installed inside the solid medium 3 formed in a substantially inverted V shape, it is not necessary to install hot / cold water piping for temperature control of the medium. Therefore, compared with the conventional one, the shape of the cultivation bed 2 can be simplified, and the cultivation bed 2 can be reduced in size.

  You may provide the groove | channel 21 for drainage in the longitudinal direction in the cross-section substantially center part on the cultivation bed 2. FIG. Thereby, since it can suppress that a surplus nutrient solution remains on the cultivation bed 2, the sanitary state in a cultivation apparatus can be kept favorable and generation | occurrence | production of a pest, etc. can be suppressed.

  The solid medium 3 is a site where the plant 6 is transplanted. In the present invention, a solid medium 3 that is lightweight and has an appropriate water retention property and has a substantially V-shaped cross section is disposed on the cultivation bed 2 in the longitudinal direction. Then, for example, planting holes 32 are formed on the inclined surfaces on both sides of the solid medium 3, and plant seedlings 6 and the like are transplanted into the planting holes 32.

  By forming the solid medium 3 in a substantially V-shaped cross section, the area of the medium per unit plane is increased compared to the case where the medium is formed in a plane, so the number of seedlings that can be planted is also increased. Can increase. Therefore, the yield per medium unit area can be improved.

  Further, for example, in the case of fruit and vegetable plants such as strawberries that stretch and hang down and bear fruit, there is a problem that the runner comes in contact with the medium and is easily damaged when a flat medium is used. On the other hand, since the runner's pain can be reduced by forming a solid medium with a substantially V-shaped cross section and inclining the cultivation surface as in the present invention, the yield and quality of fruits can be improved.

  Furthermore, since the solid medium 3 formed in a light and substantially inverted V shape is used, the volume of the medium can be greatly reduced as compared with the case where the medium is put in the entire cultivation bed as usual, and Weight can be greatly reduced.

  In addition, as compared with the case where the medium is put in the entire cultivation bed as usual, the installation is completed simply by placing the solid medium 3 on the cultivation bed 2, so that the installation work can be easily performed. Complete in a short time. Moreover, since it is only necessary to replace the solid medium 3 when replacing the medium, workability can be greatly improved.

  In addition, in this cultivation apparatus A, since the solid culture medium 3 is formed in a substantially V-shaped cross section, the water supplied to the top of the culture medium moves to the bottom of the culture medium, and a region where no water stays can be secured at the top of the culture medium. That is, by adopting this shape, a region having a drainage function at the bottom and a region having air permeability at the top can be formed in the culture medium 3, so that root decay can be suppressed.

  The solid medium 3 having a substantially inverted V-shaped cross section may be formed by disposing a pair of substantially plate-shaped solid medium members 31 in a gable roof shape.

  For example, the substantially plate-shaped solid medium member 31 to be paired faces each other, and both members 31 are tilted so that the upper edge portions are in contact with each other and leaned against each other, and the gable roof shape is formed on the cultivation bed 2. By disposing, the solid medium 3 can be disposed in a substantially inverted V shape.

  Since the substantially plate-shaped member can be used by forming the solid medium 3 having a substantially inverted V-shaped cross section using the paired solid medium member 31, the solid medium 3 (solid medium member 31) Production, transportation, installation, removal, etc. become easy. In addition, by forming the solid medium 3 with the pair of members 31, the inside of the apparatus (such as the hollow portion 51) can be visually recognized by moving only one of them, so that operations such as maintenance, inspection, and repair of the apparatus A can be easily performed. There is an advantage of becoming.

  In addition, the shape of the solid culture medium 3 should just be formed in the substantially reverse V shape, ie, the state which has an inclined surface on both sides, and is not limited narrowly by exact | strict shape, a magnitude | size, length, etc. Similarly, the solid medium member 31 need only be formed in a substantially plate shape, and is not narrowly limited by a strict shape, size, length, or the like. For example, in addition to the case where the solid medium member 31 has a quadrangular cross section, the solid medium member 31 has a hexagonal cross section (see FIGS. 1 and 2), an octagonal cross section, and the like, so that it can be easily disposed in a gable roof shape. Are widely included in the present invention.

  The internal angle θ of the solid medium having a substantially V-shaped cross section is preferably 30 to 150 degrees, more preferably 60 to 120 degrees, and most preferably about 90 degrees (80 to 100 degrees). That is, the inclination angle (solid medium gradient) θ ′ between the cultivation bed 2 and the solid medium 3 is preferably 15 to 75 degrees, more preferably 30 to 60 degrees, and approximately 45 degrees (40 to 50). Degree) is most preferred.

  The material and the like of the solid medium 3 (or the solid medium member 31) are not particularly limited as long as they are lightweight and have appropriate water retention.

  For example, rock mineral materials such as rock wool, vermiculite, perlite, zeolite, sand, Kanuma soil, glass beads, ceramics, synthetic resin materials such as urethane, nylon, melamine resin, polyacrylamide gel, wood chips, straw In addition, it is possible to use an integrally molded material derived from biological materials such as moss, charcoal, cotton, paper, and agar so as to maintain a solid shape. The means for integrally molding is not particularly limited. For example, the above-mentioned materials are put into a mold or the like by known means, and a known binder (binder) is added in some cases, followed by heating and pressure bonding.

  The weight is not particularly limited, but is preferably 0.01 to 1 kg / L in a dry state, more preferably 0.01 to 0.5 kg / L, and 0.01 to 0.4 kg / L. L is most preferred.

As an index of water retention, a preferred effective amount of water is ^{100~700L / m 3, 200~600L / m} 3 are more preferred, are most preferred 300~500L / ^{m 3.} By using the solid medium 3 having an appropriate water retention capacity, the growth of the plant 6 can be promoted, the amount of nutrient solution to be supplied can be reduced, and the generation of an excessive culture solution can be suppressed.

  As such a solid medium 3 (or member for solid medium 31) having moderate water retention, for example, a molding material in which expandable particles are expanded and a binder is added to retain the shape may be used. .

  As the expandable particles, for example, vermiculite, pearlite, expanded polystyrene, expanded polyurethane and the like can be used. In particular, vermiculite and pearlite have a high expansion coefficient and are more suitable.

  Further, when a molding material using vermiculite or pearlite as the expandable particles is used for the solid medium 3, it can be reused as horticultural soil or the like simply by crushing it after using it as the solid medium 3. Therefore, it is not necessary to treat it as industrial waste, and the environmental load can be reduced.

  When vermiculite is used as the expandable particles and the solid medium 3 is formed by expanding and forming the vermiculite, for example, water-resistant polyvinyl alcohol is added to the vermiculite as a binder, and about 800 ° C. in the mold. It can manufacture by heat-processing above or making a peroxide contact.

  The heat treatment can be performed by, for example, microwave heating. As the water-resistant polyvinyl alcohol, for example, those having a polymerization degree of 1700 or more and a saponification degree of 98 mol% or more can be used. As the peroxide, for example, 15% hydrogen peroxide water can be used.

  This molding material has moderate air permeability and water retention, and does not hinder the respiration of plant roots. In addition, it is lightweight, has a strength that does not bend or collapse during installation or transportation, and can maintain its form for a long period of time. Therefore, it is suitable as the solid medium of the present invention.

  Further, by using this molding material, the planting hole 32 for transplanting the seedling can be easily placed at an arbitrary position with an electric drill or the like, and the seedling can be planted simply by inserting the seedling into the planting hole 32. Can complete the work. Therefore, the seedling planting operation can be greatly improved.

  Furthermore, for example, in the case of a plant that stretches a runner, such as a strawberry, it is rooted relatively easily by simply contacting the runner with the molding material, and is established on the medium. Therefore, it is also effective for increasing the number of strains of plants such as strawberries and increasing the yield.

  The solid medium 3 (or the solid medium member 31) may be formed from a plurality of materials, and contains fertilizers, various materials, reinforcing materials, etc. depending on the purpose and application. You may do it.

  The irrigation means 41 is a part that irrigates the solid medium 3 from above. The irrigation means 41 extends in the longitudinal direction above the vicinity of the top of the solid medium 3 and supplies nutrient solution to the solid medium 3. For example, known means such as an infusion tube can be employed.

  The submerged sheet member 42 is a sheet-like member that covers the top of the solid medium 3 and the vicinity thereof. The nutrient solution is irrigated from the irrigation means 41 (reference numeral X1 in FIG. 2) and supplied to the submerged sheet member. The water-immersed sheet member 42 slowly supplies the nutrient solution to the solid medium 3 while keeping the nutrient solution infiltrated into the entire sheet (reference numeral X2 in FIG. 2). The nutrient solution that has reached the solid medium 3 is supplied as moisture and nutrients of the plant 6. Further, a part of the surplus liquid W1 that has not been absorbed by the plant 6 reaches the draining groove 21 and is discharged out of the device A. The surplus liquid W1 may be circulated and reused, or may be disposed as waste water as it is.

  By providing the water-immersed sheet member 42 between the irrigation means 41 and the solid medium 3, the nutrient solution can be evenly supplied to the solid medium 3 and unevenness of the nutrient solution supply can be reduced. In addition to being able to promote, irrigation can be performed efficiently, and the generation of excess culture fluid can be suppressed.

  The water-immersable sheet member 42 is not particularly limited as long as it is a sheet-like member that has water permeability and water retention and is not easily corroded. For example, aramid fiber, glass fiber, cellulose fiber, nylon fiber, vinylon fiber, polyester fiber, polyolefin fiber, non-woven fabric such as felt, non-woven fabric such as felt, carbon fiber composed of acrylic fiber, etc. Nonwoven fabric, polyester cotton, etc. can be used. Although the thickness of the sheet is not particularly limited, for example, about 0.5 to 10 mm is preferable, and about 0.5 to 3 mm is more preferable.

  The air supply pipe 5 (see FIG. 2) is a part that adjusts the temperature of the medium 3 by supplying warm air or cold air from the inside of the solid medium 3.

  In the conventional method, since the culture medium is filled in the cultivation bed, it is difficult to adjust the temperature with air. Therefore, in general, piping for hot / cold water is installed to adjust the temperature. On the other hand, in the present invention, by forming the solid culture medium 3 in a substantially inverted V shape, an inner space 51 is formed between the cultivation bed 2 and the solid culture medium 3, so by utilizing this space, An air supply pipe 5 can be installed. Therefore, by performing temperature control using the air supply pipe 5, the temperature control facility for the culture medium can be reduced in cost and simplified. In addition, the temperature can be adjusted quickly, and the temperature management within the medium itself can be facilitated.

  In addition, since the air permeability in the culture medium is maintained by forming the solid culture medium 3 in a substantially inverted V shape in cross section as described above, supplying the warm air or the cold air to the inner space 51 allows the entire culture medium to be maintained. Can be heated and cooled uniformly and quickly.

  Moreover, since temperature control by air can be performed, for example, by connecting the temperature control means of the whole cultivation facility and the air supply pipe 5, both the whole cultivation facility and the culture medium can be obtained using the same temperature control means. The temperature can be adjusted in combination. Therefore, the equipment cost can be kept low.

  Furthermore, when the solid medium 3 is formed of a pair of solid medium members 31, the inside of the apparatus can be visually recognized by moving only one of the members, so that operations such as maintenance, inspection, and repair of the air supply pipe 5 are easy.

  In addition, the solid medium 3 can be dried by supplying air from the inside (hollow part 51 side) to the solid medium 3 via the air supply pipe 5. Therefore, the water content of the solid medium 3 can be easily adjusted by using the irrigation means 41 and the air supply pipe 5 described above.

  The air supply pipe 5 may be a substantially cylindrical shape and may have a configuration including a plurality of small holes for supplying air from the inside (hollow part 51 side) to the solid medium 3, and a known member or the like is used. Although the material is not particularly limited, for example, a general synthetic resin film such as a polyvinyl chloride film, a polyolefin film, or a polyethylene film, a plastic tube, or the like can be used. .

  For example, a soft synthetic resin film or the like is formed in a substantially cylindrical shape, holes are randomly formed, and installed in the hollow portion 51. Then, air is supplied from one end of the cylindrical film to swell the film. As a result, the supplied air passes through the film, and part of the air leaks from the hole and is supplied to the solid medium 3 (reference numeral Y1 in FIG. 2). It is discharged (in the cultivation facility).

  With this configuration, the air supply pipe 5 can be easily and inexpensively installed, and the air supply pipe 5 can be easily replaced.

  The plant 6 is a plant transplanted and established in the solid medium 3. Although the strawberry 61 is described in the drawing, the present invention is not limited to this.

  That is, the present invention is effective in institutional cultivation, but can be applied to many plants that are generally cultivated in the open field, and can be fixed on the solid medium 3 (especially, crops including horticultural varieties, flower buds, etc.) ) All inclusive. From the viewpoint of having a structure that hardly damages the fruits, fruit vegetables are preferable, and in particular, strawberry, tomato, melon, and the like are more preferable.

  FIG. 3 is a schematic diagram of a temperature control system according to the present invention.

  The temperature adjusting means 52 is installed in the cultivation facility B and can perform heating and cooling or both. And the temperature in cultivation facility B is adjusted by sending out warm air or cold air (code Y2).

  On the other hand, in this system, the temperature adjusting means 52 is connected to the air supply pipe 5 via the air supply main pipe 53 in order to adjust the temperature in each cultivation apparatus A (in the solid medium 3). Then, the warm air or cold air sent from the temperature adjusting means 52 (reference Y3) is supplied to the air supply pipe 5 through the air supply main pipe 53 (reference Y4) and supplied to the solid medium 3 to adjust the temperature of the medium. I do. A part may be discharged from the other end of the air supply pipe 5 (Y5).

  The controller 54 controls whether the temperature adjusting means 52 supplies hot air or cold air to the whole cultivation facility B or each cultivation device A (solid medium 3), and switches the air supply flow path. .

  For example, when the temperature inside the cultivation facility B deviates from the set temperature by the facility temperature sensing means 55, the signal is transmitted to the control unit 54, and the control unit 54 generates hot or cold air into the cultivation facility B. In addition to instructing the air supply flow path to be supplied, the temperature adjusting means 52 is instructed to supply hot or cold air. Thereby, warm air or cold air is supplied into cultivation facility B (code Y2), and the temperature in cultivation facility B is adjusted.

  On the other hand, when the temperature in the solid culture medium 3 in each cultivation apparatus A deviates from the set temperature by the medium temperature sensing means 56, the signal is transmitted to the control unit 54, and the control unit 54 solidifies each cultivation apparatus A. Instructing switching of the air supply flow path so that warm air or cold air is supplied into the culture medium 3 and instructing the temperature adjusting means 52 to supply warm air or cold air.
