Support board for use in the greenhouse

Retired from patent. ... ... (patent application P 20 HH 821.9-23)

To grow high-quality plants in large quantities, it is advantageous to The soil required for this can be picked up, crushed, sifted, fertilized and semi-automatically or fully automatically to mix and the soil prepared in this way is also semi-mechanically or to fill them evenly into pots fully automatically, with different plant seeds individually or in a mixture in single or to sow separate crops, to cover with soil and to press down, this work in a confined space with one for this suitable sowing machine can be carried out. This not only saves manual labor, but also creates a uniformity the prerequisites for the cultivation of the plants are achieved which make the cultivation of uniform plants in large quantities essential relieved.

The ones intended for growing the plants, filled with soil and seeded or planted pots are set according to the invention in Support boards (B and C), which have a recess (B 1 a) for each pot and a laterally attached hole (B 1 b and C 2) have as a water overflow.

The pots can be filled with soil and sown manually or, as described above, by machine, semi- or fully automatically or have been planted. They are placed in the support boards by hand or automatically by the sowing machine, and likewise how the pots can be made of any material. The only essential thing is that the pots and the supporting boards are made of one material

sufficient mechanical strength exist against the action is sufficiently resistant to moisture. Both the pots and the supporting boards can after the cultivation of the Plants can be reused, only the supporting boards are advantageously used again. Will the supporting boards or the Pots are reused, so it is advantageous to feed them manually or with the help of an automatic feeder through a washing system to manage, for example an ultra-washing system (washing with ultrasound), and thus to clean gently and quickly. A suitable material for pots and support boards is, for example, a moisture-resistant plastic, e.g. polyethylene, Polyamide or polystyrene copolymers. If the pots are not to be used again, they can be made from paraffin Cardboard, made of peat or similar material, which after use rots together with earth in the open field. The earth stored in this way over a period of several years, if possible, can then be used again directly or after being dampened will. In addition to round pots (C 4), which are mentioned here as an example, can of course be used as a growing vessel for plants other vessels of any shape, e.g. angular, square or oval, can also be used. Accordingly, must the recess of the support boards can be adapted to the respective shape of the vessel. The support boards have for each pot (C 4) a recess, the diameter of the recess being slightly larger than the pot (C). When irrigating the pots (C 9) in the greenhouse water can collect in the recesses of the support boards, so that each pot is surrounded by a water supply (C 7) which is connected to the earth (C 6) through a hole in the bottom of the pot (C 5).

At the bottom of the wells, humps (C 3) are expediently attached, which on the one hand prevent the pots from standing fully on the floor, but on the other hand allow the sprinkling water (C 7) can be absorbed with the fertilizer. Through the hole on the side of the recess (B 1 b and C 2) this Water supply is limited because excess water is caused by this

Hole drains. If, therefore, when the pots are sprinkled in the greenhouse using nozzles (C 8) the water output of these nozzles is not uniform, the differences between occur from one pot to the other, balanced by the respective overflow in the individual recesses of the support boards. Through this even watering of the pots is achieved regardless of the water output of the sprinkler nozzles. This method also has the advantage that the time intervals between the individual sprinkling of the pots can be extended, because every pot has a supply of water.

In this way, the alternation between rain and drought in the field can be an excellent way of affecting the plants in the greenhouse largely transferred.

Another advantage is that in the recess of the support boards before setting the pots automatically for each culture appropriate fertilizer (C 7) can be filled. A top dressing is then no longer necessary, as the addition of water also means fertilizer, e.g. slow-acting nitrogen fertilizer or plastic-coated fertilizer as a nutrient solution (C 7), which the plants feed from below for a longer period of time Bottom hole (C 5) is fed.

The carriers are advantageously transported in the greenhouse with a forklift (forklift), because this makes it easier and flexibly adaptable to all transport problems in the greenhouse Transport is guaranteed.

There is a corresponding device on the forklift truck that allows several support boards with the pots from the sowing machine and then set them down individually on prefabricated tables, as described below. aside from that the forklift can be used to remove the cultivation containers and for other transports.

The support boards with the pots in them can be set up in the greenhouse in the usual way on tables. It is advantageous to place the supporting boards on racks (A 7, A 8 and D). These racks have parallel horizontal bars (spars) (A 8 and D 1) on which the support boards (D 2) are placed. This ensures that the supporting boards are largely free in the greenhouse (D). The ventilation underneath the deck boards is therefore not impeded (A 3) · In addition, the floor of the greenhouse can be cleaned more easily and the maneuverability of the forklift is not restricted when the deck boards are transported. That when sprinkling the. Excess water that runs off from pots can flow freely out of the greenhouse through a system of canals. On the other hand, an under-table heater can be attached to the frames (A 7 and D 3) (A 9 and D k) .

The method according to the invention can be regulated fully automatically

and thereby the growth conditions in the

Greenhouse in terms of light, air, moisture and transport

regulate much easier and cheaper.

The following examples show that the used according to the invention Plants in the Preiland both in their size and in their resistance to herbicides correspond.

example 1

The plants Triticum aestivum _9, Zea mays, Avena fatua, Beta vulgaris and Gossypium hirsutum were simultaneously

I in the Preiland
II according to the invention
III in a well-known greenhouse

After 14 days the result was as follows: The plants from I and II were in habit and height almost the same, while the plants from III were much larger and not natural in habit.
