  On the other hand, high wire attraction cultivation is one of the cultivation methods in the plant cultivation of plants. High wire attraction cultivation is used for cultivation of tomatoes etc. which need to attract a stalk as it grows. Specifically, draw a draw line parallel to the ground at a high position under the beam of a facility with a high eaves height, draw draw cords from this draw line at a predetermined interval, and fix the stems of plants to this draw cord. It is a cultivation method that attracts plants in the upright direction. By conducting high-wire attraction culture, even if the plant has a long stem length, light easily strikes the entire plant body.

However, plants that are subjected to high-wire attraction cultivation are defoliated from the lower leaves close to the ground in order to increase the growth efficiency, so the low position in the facility becomes a state where air can easily pass, and CO ₂ supply equipment thus diffused immediately be supplied to CO _2. Therefore, in order to effectively promote photosynthesis of plants, a large amount of CO ₂ needs to be supplied to increase the concentration of CO ₂ in the entire facility, resulting in a problem of cost and labor.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a management system and management method of a plant cultivation facility for efficiently promoting photosynthesis of plants in the cultivation facility.

  The management system of the plant cultivation facility of the present invention for achieving the above object is characterized in that, in the cultivation plant where a plurality of plants whose stems are attracted in a diagonal direction are planted so as to surround the set area, And a carbon dioxide supply device for supplying carbon dioxide.

  In the method of managing a plant cultivation facility of the present invention, a plurality of plants whose stems are attracted in an oblique direction are installed in the planted cultivation facility so as to surround the set area, wherein carbon dioxide is contained in the area Connected to a carbon dioxide supply device for supplying the light, a light supplementing device for illuminating the inside of the area, an illuminance sensor installed within a predetermined distance from the plurality of plants, and a fan for circulating air in the cultivation facility When the control device determines that the illuminance detected by the illuminance sensor is less than a predetermined value, the carbon dioxide supply device is paused, and the fan is continuously operated while the light supplement device is extinguished, the illuminance sensor When it is determined that the illuminance detected in the above has reached a predetermined value or more, carbon dioxide is supplied into the region by the carbon dioxide supply device to turn on the supplementary light device, and the fan is kept for a predetermined time. And it switches the intermittent operation with.

  According to the management system and management method of the cultivation facility of the present invention, photosynthesis of plants in the cultivation facility can be efficiently promoted.

It is a figure showing the state where the cultivation facility which carried the management system of the cultivation facility by one embodiment was seen from the side. It is a figure which shows the state which looked at the cultivation facility which mounts the management system of the cultivation facility by one embodiment from the top. It is a flowchart which shows the process performed with the control apparatus in the management system of the cultivation facility by one Embodiment.

  As an embodiment of the present invention, a management system applied to a plant for cultivating tomatoes will be described with reference to FIG. 1 and FIG. FIG. 1 is a view showing a state in which a cultivation facility X equipped with a cultivation facility management system 1 according to the present embodiment is viewed from the side, and FIG. 2 is a view showing a state viewed from above.

  The cultivation facility X includes bag media 101 to 114 arranged side by side so as to surround the predetermined area A on the inner ground. Each bag culture medium 101 to 114 is one in which the soil for planting plant seedlings is housed in a rectangular bag. By setting the two long sides of the rectangular shape of the bag culture media 101 to 114 up and down to stand on the ground to surround the area A, a wedge shape is formed on the ground.

  Further, at a high position under the beam in the cultivation facility X, for example, at a height position of about 200 to 220 cm from the ground, the induction line 20 is installed so as to correspond to the position of the bag culture media 101 to 114. A plurality of induction cords 301 to 314 are fixed to the induction wire 20 at predetermined intervals, and vertically drawn downward.

  Two tomato seedlings 101a, 101b... 114a, 114b are planted on the upper surface of each bag culture medium 101-114. The stems of the planted tomato seedlings 101a to 114b are clipped to the different draw cords 301 to 314 at different height positions as appropriate along with their growth, so that the plant is inclined 45 degrees to the ground from the planting position Be attracted in the direction.

  For example, tomato seedlings 101a are clipped to the draw cord 301 at the height position of T1 from the planting position, clipped to the draw cord 302 at the height position of T2, and clipped to the draw cord 303 at the height position of T3. In doing so, the stems are attracted to 45 degrees to the ground. Similarly, the stems of the other tomato seedlings 101b to 114b are also attracted as they grow.

  As described above, since the stems are attracted in the oblique direction, it is possible to cultivate in a cultivation facility with an eave height of 3 to 4 m, even in the case of a crop such as a tomato, in which the stems are extended to 7 to 8 m. In addition, when the tomato seedlings grow to a certain length, the lower aged leaves near the ground are defoliated, but by being attracted in an oblique direction, the area A is surrounded by the leaves to the part near the ground become. In addition, with regard to the part where the leaf is attached, attracting more in the diagonal direction rather than attracting in the upright direction makes the leaf denser, and the tomato seedling 101a ~ on the top of the cocoon shape formed by the bag medium 101-114 The leaves 114 b are formed in the form of a wall, and the height of the leaves is increased.

In addition, in the cultivation facility X, a CO ₂ supply device 40 is installed. A pipe 41 is connected to the CO ₂ supply device 40 and, as shown in FIG. 2, the pipe 41 is installed on the ground so as to pass through the area A. A plurality of holes are made in the tube 41, and CO ₂ is supplied from the plurality of holes into the region A by the operation of the CO ₂ supply device 40, thereby promoting photosynthesis of the tomato seedlings 101a to 114b.

  In the region A, the light supplementing device 50 is installed. The light supplement device 50 is configured of an illumination device that emits light of a frequency that contributes to light synthesis. By illuminating the interior of the area A by turning on the light correction device 50, photosynthesis of the tomato seedlings 101a to 114b is further promoted.

  In the upper part of the cultivation facility X, fans 61 and 62 are installed. By the fans 61 and 62 operating, the air in the cultivation facility X is circulated, and the photosynthesis of the tomato seedlings 101a to 114b is further promoted. Although FIG. 1 shows a state in which two fans are installed in the cultivation facility X, the number of fans is not limited to one or three depending on the size of the cultivation facility, the type of plant to be planted, etc. The above may be done.

  Further, in the vicinity of the cultivation facility X, an illuminance sensor 70 is installed. The illuminance sensor 70 detects the illuminance by sunlight during the period from sunrise to sunset. In FIG. 1, although the state which installed the illumination intensity sensor 70 in the wall surface in the cultivation facility X is shown, if it is within predetermined distance from the plant body in the cultivation facility X, it is not limited to this place. It may be installed outside X.

Further, outside the cultivation facility X, the control device 80 connected to the above-described CO ₂ supply device 40, the light supplement device 50, the fans 61 and 62, and the illuminance sensor 70 is installed. The processing executed by the control device 80 will be described with reference to the flowchart of FIG.

First, if it is before sunrise and it is determined that the illuminance value detected by the illuminance sensor 70 is less than a predetermined value (for example, 2000 lx), the CO ₂ supply device 40 is paused and the light supplement device 50 is extinguished. 61 and 62 are operated continuously (S1). Then, when it is determined that the sunrise time has passed and the illuminance by sunlight has reached a predetermined value or more based on the illuminance value detected by the illuminance sensor 70 ("YES" in S2), the process proceeds to step S3. In step S3, the CO ₂ supply device 40 is operated to start the CO ₂ supply from the pipe 41 to the area A, and the light correction device 50 is turned on, and the fans 61 and 62 are switched to intermittent operation every predetermined time ( S3). The intermittent operation of the fans 61 and 62 is performed, for example, by switching ON / OFF every one minute.

The region A, and Masugata shaped space is formed as described above, also by switching to intermittent operation fans 61 and 62 from the continuous operation for air convection is suppressed is supplied from CO ₂ supply device 40 This makes it difficult for the CO ₂ to diffuse, and in the region A, the CO ₂ concentration is kept high. Here, when the fans 61 and 62 are completely stopped to stop the convection of air, the photosynthesis of the tomato seedlings 101a to 114b is suppressed. Therefore, by switching the fans 61 and 62 to intermittent operation, it is possible to prevent excessive diffusion of CO ₂ while causing convection of air necessary for photosynthesis, and supplied CO ₂ is for tomato seedlings 101a to 114b. It is effectively used for photosynthesis. In addition, since the tomato seedlings 101a to 114b are planted so that the leaves are densely gathered by oblique attraction as described above, it is difficult for sunlight to hit the leaves inside the area A, but the light correction device 50 lights up This compensates for the illumination and promotes photosynthesis.

When it is determined that the sun is approaching and the illuminance by sunlight is less than the predetermined value based on the illuminance value detected by the illuminance sensor 70 ("YES" in S4), the process returns to step S1. When returning to step S1, the CO ₂ supply device 40 is stopped and the light supplement device 50 is turned off until sunrise of the next day, and the fans 61 and 62 are switched to continuous operation and operated.

According to the above embodiment, since it is possible to use the CO ₂ supplied by CO ₂ feeder cultivation site efficiently photosynthesis of plants, even with less than the conventional supply amount of CO ₂ plant Growth can be effectively promoted. Moreover, in the embodiment described above, since the air is difficult to diffuse in the space surrounded by the tomato seedlings, the supplied CO ₂ continues even if the temperature in the cultivation facility becomes high and the side window is opened. It is effectively used for photosynthesis.

  In the embodiment described above, by forming the area A in a shape longer in the north-south direction than in the east-west direction, and arranging the bag culture media 101 to 114 so as to surround the area A You may hit the body.

  In the embodiment described above, the case of using tomato seedlings planted in a bag culture medium has been described, but the target crop is not limited to tomato, so long as it is a plant that performs a stalk attraction treatment as it grows. It is possible to apply the system.
