Abstract

The invention relates to the field of agriculture, namely, equipment for hydroponic cultivation of plants. The purpose of the invention is to increase the productivity of plants. The hydroponic plant contains vegetative trays 1 with shading ribbons 2 of opaque foil. On the end parts of trays 1, racks 4 are fastened. Between racks 4, natures are two parallel flexible connections 5. Links 5 are able to move up or down racks 4. One edge of the tape 2 is fixed on one of the links 5, and the other hangs loose. The plant is equipped with a feed solution. In trays place planting material. At the same time, the flexible connections 5 are installed in the lower position. The plants germinate in the gap between the links 5. After that, using pegs 7, the upper edges of the tapes 2 are joined, crimping the stems of the plants. With further growth of plants, the clothespins 7 are removed, and the ribbons 2 move upward along the uprights 4, the lower parts of the plant stems are shaded. After this pegs 7 set again. Under conditions of darkness and moisture, stolons are formed on the stems, followed by tuberization. Upon reaching the desired size of the tubers produced their partial collection. 2 hp ff, 3 ill.

The invention relates to agriculture, namely to equipment for hydroponic growing of plants,

The purpose of the invention is to increase the productivity of plants.

Fig. 1 shows a hydraulic installation diagram; FIG. 2 - vegetation tray assembly, axonometric; Fig. 3 is a diagram of the tension of flexible connections.

The hydroponic plant contains inclined growing trays 1 with shading ribbons 2 of opaque foil placed on the base. Tilt trays

1 is carried out by supporting devices of adjustable height (not shown). Racks 4 are fixed to the end parts of the trays 1 by means of the supports 3. The upper end of the tray 1 is closed by a side, the lower end is open ,.

Between the uprights 4, two parallel flexible connections 5 are stretched, which are the parallel branches of a closed loop of a cable or cord. One of the branches is equipped with an elastic compensator 6, made in the form of rubber slings or twisted springs. Links 5 on racks 4 are held by tension and are able to move up or down. Shading ribbons 2 are made in the form of strips of opaque polyethylene film, with one side white and the second black, and fixed one by one on each flexible link 5 with a long edge, for example, using loops or a solid pocket. The second edge of the tape hangs loose on the side of tray 1, the length of the tapes

2 is equal to at least the distance between the uprights 4, and the width to at least the height of the uprights 4. In the case of a considerable length of tray 1, several posts are fixed to it along the length 4. between which the flexible connections 5 with the strips 2 are successively tensioned. Flexible ties 5 are provided with means for connecting the upper edges of the shading tapes 2 in the form of pegs 7.

The nutrient solution supply system comprises a nutrient solution tank 8, a pump 9, connecting pipes 10 and a control unit 11.

The installation works as follows

The control unit 11 periodically turns on the pump 9, ensuring periodic feeding from the tank 8 to the upper part of the trays 1 of the nutrient solution. Stack through trays 1, the solution is drained from their lower open ends back into the tank 8. In the trays 1, planting material is placed, for example, potatoes. At the same time, the flexible connections 5 are mounted on the uprights 4 in a lower position. The plants germinate in the gap between the flexible connections 5 with the upper edges of the ribbons 2 fixed to them. After that, the upper and

butt edges with each other, crimping the stems of plants and fixing them at the same time. At the same time, the access of light to the root system inside trays 1 is prevented. With the further growth of plants, the clothespins

7 is removed, and the flexible links 5 with ribbons 2 move upward along the uprights 4, the lower parts of the plant stems are shaded. After this pegs 7 set again. In conditions of darkness and high humidity

stalks start stolon formation followed by tuberization. When the first tubers reach the sizes corresponding to the sizes of the conditioned planting material,

partial harvesting; To do this, lift the lower free-hanging edges of the ribbons 2, opening access to the space inside trays 1 and under the ribbons 2. The conditioned tubers tear off, while, if necessary, lifting the root mat. Since the stems are fixed between the flexible connections 5, the plants do not overturn during this operation. The length and width of the ribbons 2 makes it possible to shade the lower part of the crown.

at any position of the flexible links 5 on the uprights 4.

Compensator 6 provides constant tension for flexible connections 5 and fixation of the aerial parts of plants. If necessary, the fixation of the high aboveground part between the uprights 4 above the flexible links 5 additionally pulls the trellis (not shown).

Partial tuber harvesting

several times during the growing season, it is possible to ensure the production of conditioned tubers uniformly in time and, in general, to increase the productivity of plants.
