  As shown in FIG. 1, the plant cultivation system includes a plurality of racks 1 for cultivating a plant P. As shown in FIG. 3, this plant cultivation system is installed indoors and has traveling lines A, B, and C for each step of seeding, raising seedlings, and planting. A plurality of racks 1 are arranged on each of the traveling lines A, B, and C. The plurality of racks 1 intermittently move along the traveling lines A, B, and C to the contents that can be separated.

  As shown in FIG. 1, the plant P is cultivated in the cultivation tank 2 set in the rack 1. The cultivation tank 2 includes a tray portion 21 for storing water such as fresh water or a culture solution, a nursery pallet 22 placed on the bottom surface of the tray portion 21 or a plate-shaped planting pallet 23 for closing the upper surface of the tray portion 21 (see FIG. 3). ) And.

  The nursery pallet 22 is used in the step of sowing and the step of raising seedlings. The nursery pallet 22 is made of sponge, urethane foam, or the like. The seedbed pallet 22 has vertical and horizontal cuts (not shown) for easy cutting into planting segments (not shown) for growing one plant P. The seedbed pallet 22 has a recess (not numbered) for placing a seed and a notch (not shown) for placing a seed in the center of each area surrounded by the cut lines. The nursery pallet 22 is placed on the bottom surface of the tray section 21.

  The planting palette 23 is used in the planting process. In the planting process, the plant P grows large until it can be shipped in the planting segment. The planting pallet 23 is a panel having many holes. A cultivation pot (not shown) is fitted into each hole. A planting segment is placed in the cultivation pot.

  In the planting pallet 23, the plant P that grows in the planting process is larger than the plant P that grows in the sowing and nursery process. Therefore, the distance between the large number of holes formed in the seedbed pallet 22 is set larger than the distance between the large number of seeds sown by the seedbed pallet 22. The number of seedlings cultivated on the planting pallet 23 is smaller than the number of seedlings cultivated on the seeding step and the seedling raising step.

  As shown in FIG. 2, the rack 1 in which such a cultivation tank 2 is set includes four columns 11, a plurality of pairs of main beams 12 and a plurality of pairs of sub-beams 13 spanning the two columns 11. And a plurality of crosspieces (not shown) bridged between the pair of main beams 12, and casters 15 attached to the lower ends of the columns 11. The four columns 11 are arranged such that the pair of columns with a wide interval and the pair with a narrow interval are located at the corners of the rectangle in plan view.

  The main beam 12 is bridged between the columns 11 having a wide space. The sub beam 13 is bridged between the columns 11 having a narrow space. The main beam 12 and the sub-beam 13 are fixed to the column 11 with a certain space in the height direction. One cultivation tank 2 is placed (set) on the crosspiece that is bridged between the pair of main beams 12. The illustrated rack 1 is provided with a main beam 12, a sub-beam 13 and crosspieces in four stages so that four cultivation tanks 2 can be set.

  The rack 1 is provided with a vertical water supply pipe 16 and a vertical drain pipe 17. The water supply pipe 16 is spanned by the sub-beams 13 arranged in the vertical direction on one end side of the rack 1. The water supply pipe 16 is attached to the upper surface opening side of one end of the tray part 21 so as to supply water such as fresh water or a culture solution into the tray part 21 of each cultivation tank 2. The drain pipe 17 is bridged over the sub-beams 13 arranged in the vertical direction on the other end side of the rack 1. The drain pipe 17 is attached to the bottom side of the other end of the tray portion 21. The water that has not been sucked up by the plants P is drained from the drain pipe 17 while being supplied to the tray portion 21.

  At the lower part of the rack 1, a tank 18 and a pump (not shown) are placed in order to circulate the water returned to the drain pipe 17 to the water supply pipe 16. When the water is reduced by being sucked up by the plant P, the reduced amount of water is supplied to the tank 18.

  The rack 1 includes a light source 19. The light source 19 is attached to, for example, the lower side of the crosspiece in order to uniformly illuminate the plants P in the cultivation tank 2. As the light source 19, for example, a tubular LED lamp or a flat LED lamp is adopted. The number of light sources 19 is not limited to two as shown, and may be one or three or more. The LED lamp can emit light having a wavelength suitable for the growth of the plant P. A power supply line (not shown) for driving the pump and for causing the light source 19 to emit light is wired in the rack 1.

  An electric wire 3 for driving the pump and causing the light source 19 to emit light is installed above the traveling lines A, B and C, for example, near the ceiling (not shown). The electric wire 3 includes a main line 31 that is installed at a position higher than the rack 1 in the same direction as the traveling line, and a branch line 32 that branches from the main line 31 and hangs down toward the rack 1. The branch line 32 is connected to the main line 31 so as to follow the movement of the rack 1. The power supply line wired in the rack 1 includes an outlet (not shown) connected to the branch line 32.

  Such a rack 1 is provided on a sowing running line (hereinafter referred to as a "seeding line") A, a seedling raising running line (hereinafter referred to as a "seeding raising line") B, and a planting running line (hereinafter referred to as "the seeding line"). A plurality of units (4 units in the drawing) are arranged on C so that they can be brought into and out of contact with each other. The long sides of the rack 1 contact and separate from each other. The rack 1 intermittently advances on each of the traveling lines A, B, and C in accordance with the growth situation of the plant P, with the length of the short side as one pitch.

  The rack 1 advances when pushed by an operator. In this case, each traveling line A, B, C is provided with a stopper that stops the rack 1 at a predetermined position. However, the caster 15 may be driven by a motor (not shown), and the motor may be controlled by the control means. The control means drives the motor at a predetermined timing for a certain period of time to intermittently advance the rack 1 at a certain pitch. The constant pitch at which the rack 1 advances is the width of the rack 1.

  Each traveling line A, B, C is equipped with a pair of parallel guide rails 4. The distance between the pair of guide rails 4 is substantially the same as the length of the long side of the rack 1. The pair of guide rails 4 are fixed to the floor so as to hit the pair of casters 15 of the rack 1 or the sub beam 13 at the bottom of the rack 1.

  In the sowing line A, the rack 1 is intermittently advanced at a constant pitch at regular intervals (for example, 2 days) until the seeds sown on the nursery pallet 22 germinate (for example, 8 days). The plant P germinated on the nursery pallet 22 is much smaller than the plant P grown until it can be harvested. Therefore, the pitch of the seeds sown on the nursery pallet 22 is narrower than the pitch of the holes of the planting pallet 23.

  The nursery pallet 22 is placed on the bottom surface of the tray section 21. The cultivation tank 2 in which the nursery pallet 22 is placed on the bottom surface of the tray portion 21 is placed (set) on the crosspiece of the rack 1.

  In the seedling raising line B, the seedlings germinated on the seedbed pallet 22 grow, that is, until the roots grow, the stem becomes thicker, and the leaves appear (for example, 8 days), and the rack 1 is at regular intervals (for example, 2 days). It moves forward intermittently at a constant pitch. The seedbed pallet 22 and tray section 21 used in the seedling raising line B are the same as the seedbed pallet 22 and tray section 21 used in the seeding line A. Therefore, the rack 1 moved on the seeding line A moves to the seedling raising line B as it is. Alternatively, the cultivation tank 2 set in the rack 1 of the sowing line A is transferred (set) to the rack 1 of the seedling raising line B.

  In the constant planting line C, the rack 1 is intermittently advanced at a constant pitch at regular intervals (for example, 1 day) until the plant P grown in the seedling raising line B is further grown and harvested (for example, 16 days). In the planting line C, the cultivation tank 2 in which the planting pallet 23 covers the upper surface of the tray portion 21 is used. A cultivation pot is fitted into the hole of the planting pallet 23 of the cultivation tank 2. A planting segment obtained by cutting the nursery pallet 22 is placed in the cultivation pot. In each planting segment, one plant P grows. The cultivation tank 2 in which the cultivation pot is set is set in the rack 1 of the planting line C.

  Here, a plant cultivation method by the plant cultivation system according to the present invention will be described with reference to FIGS. 3 to 5.

  First, the seeds are sown on the nursery pallet 22. The seeds are sown at regular pitches in the depressions or cuts in the nursery pallet 22. Next, the cultivation tank 2 in which the seedbed pallet 22 seeded is placed on the bottom surface of the tray portion 21 is set in the rack 1. The cultivation tank 2 is set in a plurality of stages (four stages in the drawing) in the rack 1. As shown in FIG. 4A, the racks 1 are arranged at the rear end of a plurality (three in the drawing) of the racks 1 arranged on the seeding line A. Therefore, as shown in FIGS. 1 and 4B, in the seeding line A, four racks 1 are cultivated in a line.

  As shown in FIG. 2, a water supply pipe 16 and a drain pipe 17 are attached to the tray portion 21 in the rack 1 arranged at the rear end. Fresh water is stored in the tank 18 provided in the rack 1. Fresh water circulates between the water supply pipe 16 and the drain pipe 17, and the nursery pallet 22 in the cultivation tank 2 is immersed in fresh water.

  The water supply pipe 16 and the drain pipe 17 are also connected to the tray portions 21 of the three racks 1 that are already arranged. The branch lines 32 of the electric wires 3 are connected to the racks 1 arranged at the rear end by an outlet provided in the power supply line. The power supply line and the branch line 32 of the electric wire 3 are also connected to the three racks 1 already arranged. By connecting the power supply line to the branch line 32 of the electric wire 3, the pump is driven to circulate fresh water, and the light source 19 in the rack 1 illuminates the nursery pallet 22.

  The buds sown on the nursery pallet 22 germinate as the number of days passes. When the rack 1 of the sowing line A advances by one pitch every two days, for example, the racks 1 arranged at the rear advance to the beginning on the sixth day, as shown in FIG. 4B. The rack 1 goes straight along the guide rails 4. Four racks 1 advance together. The rack 1 is smoothly advanced by the casters 15. When the rack 1 in the seeding line A advances, the branch line 32 of the electric wire 3 follows.

  As shown in FIG. 4 (c), the plants P in the rack 1 lined up at the head are moved from the seeding line A to the seedling raising line B after being cultivated for a certain period of time, for example, 2 days. When the rack 1 separates from the seeding line A, the branch line 32 of the electric wire 3 is unplugged from the outlet of the power supply line. At the beginning position of the sowing line A, there is a space. The plant P sown on the nursery pallet 22 in the top rack 1 has started to grow leaves and has grown into a small seedling.

  Next, as shown in FIG. 4D, the three racks 1 arranged side by side advance integrally by one pitch, leaving a space at the rear. As shown in FIG. 4A, a new rack 1 is arranged in this rear space.

  As shown in FIG. 3, the racks 1 separated from the seeding line A are arranged at the rear end of the seedling raising line B. The power supply line of the rack 1 and the branch line 32 of the electric wire 3 of the seedling raising line B are connected. A culture solution is stored in the tank 18 of the rack 1. The culture solution circulates in the tray portion 21 by the water supply pipe 16 and the drain pipe 17. In the seedling raising line B as well, as in the seeding line A shown in FIG. 4, the rack 1 is intermittently advanced every fixed period, for example, every two days.

  The racks 1 arranged in the seedling raising line B are regulated by the guide rails 4 and intermittently move forward. The rack 1 is smoothly advanced by the casters 15. The plant P in the cultivation tank 2 grows by the culture solution and the light source 19. For example, if the rack 1 advances by one pitch every two days, the rack 1 arranged at the end advances to the beginning in 6 days. The plant P in the cultivation tank 2 stored in the top rack 1 grows for two days, then leaves the subsequent rack 1 and moves from the seedling raising line B to the planting line C. At this time, the branch wire 32 of the electric wire 3 is removed from the outlet of the rack 1.

  As the plant P moves to the planting line C, the nursery pallet 22 is cut at the notches and separated into planting segments. The planting segment is placed in the growing pot. This cultivation pot is fitted into a hole provided in the planting pallet 23. The planting pallet 23 closes the upper surface of the tray portion 21, whereby the cultivation tank 2 is set. In this cultivation tank 2, the number of holes in the planting pallet 23 is smaller than the number of depressions in the nursery pallet 22 so that large-grown plants P are not crowded.

  As shown in FIG. 5, the cultivation tank 2 is stored in the rack 1 of the planting line C. Even in the planting line C, four racks 1 are lined up. That is, as shown in FIG. 5A, three racks 1 are lined up, and a new rack 1 is lined up in the space provided at the rear. As shown in FIG. 5B, the plant P on the traveling line of the fixed plant grows until it can be cultivated in a fixed period (eg, 16 days). Therefore, every 4 days, one pitch is advanced. The rack 1 intermittently advances along the guide rails 4. The rack 1 is smoothly advanced by the casters 15.

  The water supply pipe 16 and the drain pipe 17 provided in the rack 1 of the planting line C are attached to the tray portion 21 of the cultivation tank 2 stored in the rack 1. A nutrient solution for planting is supplied from the water supply pipe 16 into the tray portion 21 and drained from the drain pipe 17. The lower part of the cultivation pot is in a state of being immersed in the nutrient solution in the tray section 21.

  The rear rack 1 advances to the beginning on the 12th day. The plant P on the top rack 1 grows until it can be harvested after 4 days. As shown in FIG. 5 (c), the first rack 1 on which the plant P is ready to be harvested advances from the subsequent rack 1. At this time, the branch line 32 of the electric wire 3 is removed from the power supply line of the rack 1, and the water supply pipe 16 and the drain pipe 17 are removed from the tray portion 21. The cultivation tank 2 stored in the top rack 1 is taken out from the rack 1. The cultivation pot of this cultivation tank 2 is pulled out from the hole of the plate and shipped.

  As shown in FIG. 5D, three racks move forward, and a space is opened at the rear. In this space, a new rack 1 sent from the seedling raising line B is arranged as shown in FIG.
