Description

  The present invention relates to a cultivation apparatus.

  For example, JP 2010-019074 A (hereinafter referred to as Patent Document 1) describes a greenhouse having a cultivation space separated from the outside by a film supported by air pressure. According to this greenhouse, since the film has light permeability and no frame for supporting the film, sunlight necessary for plant photosynthesis can be sufficiently taken into the cultivation space.

  However, in this greenhouse, while the internal pressure of the cultivation space is maintained, cultivation is performed in a state where there is no wind or close to it. In other conventional greenhouses, cultivation is carried out in a state of no wind or close to it. The plant leaf epidermis has pores that take in carbon dioxide necessary for photosynthesis, but in the absence of wind, once carbon dioxide is taken in from the pores, the leaf epidermis does not contain carbon dioxide The air layer (hereinafter referred to as the foliar boundary layer) is stagnant. Moreover, even if carbon dioxide gas is introduced into the cultivation space in this state, uptake of carbon dioxide from the pores is hindered by the foliar boundary layer. Therefore, it has been difficult to promote photosynthesis even when sunlight is sufficiently applied.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the technical scope of the present invention is not limited to the contents of the following description.

  The cultivation apparatus according to Example 1 of the present invention includes films 1 and 2, cultivation spaces 3 and 4, terminal units 5 and 6, air conditioners 7 and 8, pressurization means 9, weight receiver 10, weight 11 and drainage means. 12.

  The films 1 and 2 are light transmissive. As shown in FIGS. 1 and 2, the film 1 covering the cultivation space 3 has one end connected to the terminal unit 5 and the other end connected to the terminal unit 6. Similarly, the film 2 covering the cultivation space 4 has one end connected to the terminal unit 5 and the other end connected to the terminal unit 6. The lower portions 1a and 2a of the films 1 and 2 are fixed using the weight receiver 10 and the weight 11 as shown in FIGS.

  As shown in FIG. 4, the weight receiver 10 includes a bottom wall 10a and side walls 10b and 10c that are inclined inward. In this embodiment, the weight receiver 10 is buried in the ground as shown in FIG. According to this configuration, when a pulling load is applied to the weight receiver 10, the side walls 10b and 10c try to open outward, but the outer surface of the side walls 10b and 10c is in contact with the soil. In order to prevent the movement of the side walls 10b and 10c as a resistance, the weight receiver 10 has a high strength against a pulling load.

  As shown in FIG. 4, the weight 11 is disposed inside the weight receiver 10. As the weight 11, a flexible container containing a liquid is used. As shown in FIG. 4, the weight 11 is exposed from between the side walls 10 b, 10 of the weight receiver 10, and is arranged inside each cultivation space 3, 4. According to this structure, the effect which relieve | moderates the fall of the temperature of each cultivation space 3 and 4 is acquired by the thermal storage and heat dissipation effect | action of a liquid.

  The lower portions 1a and 2a of the films 1 and 2 are disposed so as to be interposed between the weight receiver 10 and the weight 11 as shown in FIG. According to this configuration, the lower portions 1a and 2a of the films 1 and 2 are sandwiched between the weight receiver 10 and the weight 10, and the surface pressure acts on both surfaces of the films 1 and 2, and the frictional force Films 1 and 2 can be firmly fixed. Further, as described above, since the weight receiver 10 has a high strength against the pulling load, the films 1 and 2 can be prevented from being lifted. Further, the weight receiver 10 and the weight 11 are in close contact with the lower portions 1a and 2a of the films 1 and 2, whereby the airtightness can be improved.

  After the films 1 and 2 are installed as described above, air is injected between the films 1 and 2 and the ground 13 using the pressurizing means 9. Each cultivation space 3 and 4 is separated from the outside by the films 1 and 2 supported by the pressure of the air injected using the pressurizing means 9. According to this configuration, since the frames 1 and 2 are not required to form the cultivation spaces 3 and 4, the cultivation spaces 3 and 4 can be formed at a low cost. As shown in FIG. 1, the cultivation spaces 3 and 4 separated from the outside by the films 1 and 2 that are supported by air pressure in this way have an elongated shape in a straight line.

  As shown in FIG.1 and FIG.3, it is preferable that each cultivation space 3 and 4 is arrange | positioned so that each film 1 and 2 which covers each cultivation space 3 and 4 may surface-contact. According to this structure, even when the external pressure by a wind, rain, or snow is received, the internal pressure of each cultivation space 3 and 4 can mutually act and the deformation | transformation of each film 1 and 2 can be suppressed.

  In the invention described in Patent Document 1, since each cultivation space is arranged without a surface contact between a film covering one cultivation space and a film covering another cultivation space, an external pressure covers each cultivation space. Concentrate on each film. Therefore, the form is easily deformed. Moreover, in order to prevent a deformation | transformation of a film, you must always or frequently implement introduction of the air to each cultivation space, and exhaust_gas | exhaustion from each cultivation space according to an external pressure. In addition, since outdoor air frequently circulates in each cultivation space, pests and bacteria that adversely affect the growth of plants are likely to enter and easily spread in each cultivation space.

  In contrast, according to the present embodiment, the external pressure is dispersed throughout the films 1 and 2 covering the cultivation spaces 3 and 4, and furthermore, the cultivation spaces 3 and 4 are caused by the internal pressure of the adjacent cultivation spaces 3 and 4. Since the two support each other, deformation of the films 1 and 2 hardly occurs. Therefore, it is not necessary to inject air into the cultivation spaces 3 and 4 and exhaust air from the cultivation spaces 3 and 4 constantly or frequently according to the external pressure. Moreover, it is not necessary to constantly monitor the external pressure. Furthermore, since outside air does not circulate frequently in each of the cultivation spaces 3 and 4, it is possible to greatly reduce the invasion and spread of harmful insects and bacteria that adversely affect plant growth.

  As shown in FIG. 1, the terminal units 5 and 6 include passages 5 a and 6 a that communicate with the cultivation spaces 3 and 4, and air conditioners 7 and 8. Moreover, as shown in FIG. 2, the terminal units 5 and 6 are provided with doors 5b and 6b through which persons working in the cultivation spaces 3 and 4 can enter and exit. These doors 5b and 6b are preferably airtight.

  The air conditioners 7 and 8 are used in a state where gas is confined in the cultivation spaces 3 and 4 and the passages 5a and 6a. As shown in FIG. 1, the air conditioners 7 and 8 include blowers 7a and 8a. The wind generated by operating the blowers 7a and 8a is discharged from the air conditioners 7 and 8. This wind generates a flow of wind (airflow 14) in each of the cultivation spaces 3 and 4, but this airflow 14 is not for maintaining the internal pressure of each of the cultivation spaces 3 and 4, so that Patent Literature 1 is used. Different from the airflow described in. In the present embodiment, the wind discharged from the air conditioners 7 and 8 is directed to the plants 15 cultivated in the cultivation spaces 3 and 4. Since each cultivation space 3 and 4 has an elongate shape in a straight line, the passage of the wind is good and the decrease in the wind speed can be suppressed. As a result, an appropriate wind can be applied to each plant 15 without being biased.

  The wind discharged from the air conditioners 7 and 8 circulates in the cultivation spaces 3 and 4 through the passages 5a and 6a and is cultivated in the cultivation spaces 3 and 4 as shown in FIGS. Applied to plants. It is preferable that the air conditioners 7 and 8 include wind speed adjusting means (not shown) that can discharge the wind that can adjust the wind speed of the wind circulating in the cultivation spaces 3 and 4 to a predetermined wind speed. The wind speed adjusting means includes an anemometer and a control device that adjusts the outputs of the blowers 7a and 8a according to the wind speed detected by the anemometer. According to this configuration, the air conditioner 8 installed in the terminal unit 6 even when the wind speed decreases before the wind discharged from the air conditioner 7 installed in the terminal unit 5 reaches the terminal unit 6. The anemometer included in the air conditioner detects a decrease in the wind speed, and based on that, the control device increases the output of the blower 7a or 8a to increase the amount of wind discharged from the air conditioner 7 or 8. Thereby, the wind speed of the wind circulating to each cultivation space 3 and 4 can be returned to a predetermined wind speed. As a result, it is possible to apply a uniform wind to all the plants cultivated in each of the cultivation spaces 3 and 4.

  The air conditioners 7 and 8 are also preferably equipped with carbon dioxide adjusting means (not shown) that enables discharge of carbon dioxide that can adjust the carbon dioxide concentration in the cultivation spaces 3 and 4 to a predetermined concentration. The carbon dioxide gas adjusting means includes a concentration meter and a control device that adjusts the amount of carbon dioxide gas supplied from the carbon dioxide gas cylinder 16 in accordance with the concentration detected by the concentration meter. Carbon dioxide gas supplied from the carbon dioxide gas cylinder 16 is discharged from the air conditioners 7 and 8 together with the wind. According to this configuration, even when the carbon dioxide concentration in each of the cultivation spaces 3 and 4 is reduced, the densitometer detects the decrease in concentration, and based on that, the control device increases the amount of carbon dioxide supplied from the carbon dioxide gas cylinder 16, The amount of carbon dioxide discharged from the air conditioners 7 and 8 is increased. Thereby, the density | concentration of the carbon dioxide in each cultivation space 3 and 4 can be returned to a predetermined density | concentration. As a result, carbon dioxide gas can be effectively provided to each plant 15. Carbon dioxide is moderately used for accelerating the growth of the plant 15, but the amount of carbon dioxide used is small because it is used in a sealed space.

  The air conditioners 7 and 8 are also preferably provided with temperature and humidity adjusting means (not shown) that can discharge air that can adjust the temperature and humidity of the cultivation spaces 3 and 4 to a predetermined temperature and humidity. The temperature / humidity adjusting means includes a temperature / humidity meter and an air conditioner that supplies air for adjusting the temperature / humidity according to the temperature / humidity detected by the temperature / humidity meter. The air supplied from the air conditioner is discharged from the air conditioners 7 and 8 together with the wind. According to this configuration, the temperature and humidity meter detects changes in the temperature and humidity of each of the cultivation spaces 3 and 4, and the air conditioner supplies warm air, cold air, low humidity or high humidity air based thereon, and the air conditioner 7 and 8 are discharged. Thereby, it becomes possible to maintain the temperature and humidity of each cultivation space 3 and 4 at predetermined temperature and humidity. In addition, for example, the humidity of each of the cultivation spaces 3 and 4 can be reduced to promote the transpiration of the plant 15 and increase the nutrient absorption from the roots.

  The drainage means 12 is installed in order to exclude rainwater that flows down between the films 1 and 2 that are in surface contact with each other. Rainwater (including snow) accumulates at the upper part of the part where the films 1 and 2 are in surface contact, and when it reaches a certain amount, it spreads and flows down the part where the films 1 and 2 are in surface contact. Therefore, as shown in FIG. 4, the water collecting portion 12a constituting the drainage means 12 is preferably installed at the lower portion of the portion where the films 1 and 2 are in surface contact. Moreover, the weight receptacle 10 in which the water collection part 12a is installed functions as a gutter, and can prevent that drainage flows into the ground. As the water collection part 12a, it is preferable to use a perforated pipe in order to collect water efficiently. In this embodiment, as shown in FIG. 4, the perforated pipe that is the water collecting portion 12 a is connected to the drain pipe 12 b that constitutes the drainage means 12, thereby enabling the drainage of rainwater.

  Since the films 1 and 2 have light transmittance, the cultivation apparatus comprised as mentioned above can fully take sunlight in each cultivation space 3 and 4. Moreover, since each cultivation space 3 and 4 is linearly elongate, the passage of the wind in each cultivation space 3 and 4 is favorable, and applies moderate wind to all the plants 15 grown in each cultivation space 3 and 4. be able to. And this wind can destroy the leaf surface boundary layer stagnating in the leaf epidermis of the plant 15, and can easily distribute carbon dioxide in the vicinity of the pores. As a result, a large amount of carbon dioxide necessary for photosynthesis can be taken in from the pores, and photosynthesis can be promoted. Moreover, in the state which confined gas to each cultivation space 3 and 4 and channel | path 5a, 6a, the wind discharged from the air conditioners 7 and 8 is circulated to each cultivation space 3 and 4 via channel | path 5a, 6a. Therefore, it is difficult for pests and bacteria to enter the cultivation spaces 3 and 4, and the spread of the pests and bacteria in the cultivation spaces 3 and 4 can be prevented.

  The cultivation facility which concerns on Example 2 of this invention differs in the structure for fixing the lower parts 1a and 2a of the films 1 and 2 from the cultivation apparatus which concerns on Example 1. FIG. That is, in this embodiment, as shown in FIG. 5, a pile 17 that is driven into the ground in contact with the side walls 10 b and 10 c of the weight receiver 10 is provided.

  In the present embodiment, the weight receiver 10 is installed on the ground 13. However, since the portion of the pile 17 that is in contact with the side walls 10b and 10c of the weight receiver 10 becomes a resistance and prevents the side walls 10b and 10c from opening to the outside, the strength against the pulling load is strong. Accordingly, the lower portions of the films 1 and 2 can be firmly fixed. Moreover, since the operation | work which embeds the weight receptacle 10 in the ground can be abbreviate | omitted, it becomes possible to install a cultivation apparatus more cheaply.

  As shown in FIGS. 6 and 7, the cultivation apparatus according to Example 3 of the present invention is the same as the cultivation apparatus according to Example 1 in that an intermediate unit 18 is installed between the terminal units 5 and 6. Different.

  As shown in FIG. 6, the intermediate unit 18 includes passages 18 a and 18 b that individually communicate with the cultivation spaces 3 and 4, and air conditioners 7 and 8 that can discharge wind to the cultivation spaces 3 and 4, respectively. It has. The films 1 and 2 are connected to the intermediate unit 18. Similarly to the terminal units 5 and 6, the intermediate unit 18 also includes an airtight door 18 f. The passages 18a and 18b pass through the intermediate unit 18 and are partitioned by a partition wall 18c. The air conditioners 18d and 18e are configured in the same manner as the air conditioners 7 and 8 of the first embodiment.

  By installing the intermediate unit 18, more precise control of the air flow 14, control of the carbon dioxide concentration, and control of temperature and humidity become possible. Moreover, it becomes possible to lengthen the full length of each cultivation space 3 and 4. FIG. A plurality of intermediate units 18 can be installed between the terminal units 5 and 6 according to the cultivation area.

  The cultivation apparatus which concerns on Example 4 of this invention sets the cultivation apparatus which concerns on Example 3 as 1 unit, and has arrange | positioned several this unit in parallel. Adjacent unit films are in surface contact.

  Specifically, as shown in FIG. 8, the first unit U1 and the second unit U2 are arranged in parallel. Both the first unit U1 and the second unit U2 are cultivation devices according to the third embodiment. The film 2 covering the cultivation space 4 of the first unit U1 is in surface contact with the film 1 covering the cultivation space 3 of the second unit U2. According to this configuration, not only the cultivation area simply increases, but also the cultivation spaces 3 and 4 are supported with each other by the internal pressure of each cultivation space 3 and 4. It is possible to reduce the deformation of 2 and increase the strength against external pressure.
