Description

The invention relates to agriculture, namely, equipment for hydroponic cultivation of plants from tubers, bulbs, rhizomes and other planting material of increased size.

The purpose of the invention is improving productivity, simplifying the design and operation.

In Fig, 1 shows the proposed device, a cross section; figure 2 is the same, a longitudinal section.

The device contains a vegetation bath 1. On the supports installed along its sides 2, landing covers are freely placed in the form of floating foam panels 3 with plant openings and planting material holders in the form of hooks 4 from a corrosion-resistant wire. The hooks 4 may have a Π, V or U-shape with an elongated base 5. The hooks 4 are inserted in the panel 3 next to the holes so that their free ends 6 are located in or under the hole. Hooks 4 are held in the foam due to friction and have the ability to vertically move with fixation on friction in any intermediate position. The ends 6 of the hooks can be pointed if necessary, and the bases 5 are bent laterally at the ends.

At the bottom of the bath 1 with a gap relative to its bottom and walls, at least one U-shaped box 8 is fixedly fixed by means of latches 7.

The periodic underflooding system includes a compressor 9, an automation unit 10 with a top-level underflooding regulator 11, a drain valve 12 and connecting pipes 13. The output of the compressor 9 and the input of the automation unit 10 is connected to the space under the bottom of the inverted duct 8 through a tube 14.

The proposed device operates as follows.

Before starting work, the hooks 4, if necessary, are removed from the panel 3 and the shape of the bend for this planting material is changed. At the ends 6 of the hooks 4, planting material, for example, potato micro-tubers, is pierced. Then the base 5 pierce the foam panel 3, setting the planting material at the desired distance from it in the alignment of the holes or under them. The panel 3 is installed on the supports 2 and the regulator 11 sets the upper level of periodic flooding so that at least part of the micro-tuber is wetted.

The system of periodic flooding in this case works as follows.

The compressor 9 pumps air under the duct 8. The solution from under it is squeezed out through the gaps at the bottom and walls of the bath 1 into its upper part. Upon reaching a predetermined upper level, the controller 11 through the automation unit 10 gives a command to turn off the compressor 9. The air from under the duct 8 is vented through the drain valve 12 and the solution level in the upper part of the bath 1 drops. When the whole solution merges back under box 8 and the air pressure under it becomes close to atmospheric, the automation unit 10 will issue a command to 'turn on compressor 9. The cycle repeats.

When organizing conveyor sowing, planting is performed daily by installing panels 3 next to each other. When the entire area of the bath 1 will be covered with panels 3, before landing, the conveyor is first moved. To do this, using the controller 11 increase the upper level of flooding so that the foam panels 3 are afloat. The last panel 3 with adult plants is removed, and then all PanDi 3 are moved to the side on the solution surface. Moving can be done by pushing the last panel in the row 3, because of the low resistance of the floating panels 3 this will be enough to move the entire row.

After moving, the upper level controller 11 is returned to its original position, and a panel 3 with a new planting material is installed on the conveyed space on the vacated space. In the process of moving along the conveyor, the hooks 4 are buried under the panel 3, simulating the hilling of plants, which contributes to additional tuberization.

When growing other plants that do not require hilling, you can first install the hooks 4 in the lower positions, and then, as the roots grow back, move them to the upper position. Moreover, throughout the growing season, except for the period of conveyor movement, it is sufficient to periodically create a thin layer of the solution at the bottom of the installation, which reduces the energy consumption for pumping the solution.

Panels 3 and hooks 4 are reusable. Since the automation unit 10 can be made remote, there is no danger of electric shock when working with the device.
