Cutture Plate for the Rootina of Youna PflantS
The Invention relates to a culture plate for the rooting of young plants with
rows
arranged in parallel with each other in order to accommodate pots oriented
downwards with holes in the base of the pots and with a surrounding edge
enclosing
the culture plate.
A well-known culture plate exhibits pot-like hollows or pots which are located
in rows
arranged in parallel with each other, are open at the top and have an opening
with a
smaller diameter in their base. The smaller opening in the base serves to
press the
balls of soil with root penetration, together with the young plant, out of the
pot-like
hollow trom the bottom and to allow surplus water to drain away. This culture
plate
has a rectangular shape and a surrounding edge.
Another culture plate well-known from EP 0 657 096 A1 has two supports in the
first
row Instead of the two outermost pots and, in the last row Instead of the two
second-outermost pots, two supports which are hollow, open at the bottom and
oriented upwards. In this case, the two second-outermost pots in the first row
are
each provided with one supporting ring on the base, the two outermost pots in
the
last row are each provided with one supporting ring on the base and one
centering
attachment is provided at the top end of each support. The supports exhibit an
opening in their walls pointing towards the culture plate. The supporting
rings on the
base of the two outermost pots and of the two second-outermost pots exhibit
lateral
recesses.

A great deal of water is required in order to water the plants In these well-
known
culture plates.
For various reasons, the objective is to minimize the consumption of water:
1. A high consumptlon of water has a negative Influence on the greenhouse
climate.
Diseases (above all, fungal diseases) are promoted by this.
2. Water is not always available in a sufffcient quantity, e.g. on Tenerife.
The invention Is based on the task of creating such a culture plate for which,
in
comparfson, very littie water is necessary for the watering of the plants.
According to the invention, this task Is solved by arranging the plate base In
a deeper
position In relation to the edge and by providing transversely directed
grooves In the
plate base at a predefinable distance apart.
The grooves are expediently provided with at least one hole through which the
surplus water flows into a water-collection system.
it is recommended that multiple pots arranged next to each other should be
suspended in the grooves.
The culture plate is expediently equipped with holder grooves in which the top
edge
of the multiple pots is supported.
Furthermore, the top edge of the multiple pots can be shaped in such a way
that it
closes the groove completely.
2

CA 02283546 1999-09-24
In further development of the invention, the multiple pots may be provided
with at
least one hole for the removal of the surplus water and may end above the base
of
the groove.
It is advantageous that those areas of the plate base of the culture plate
located
between two adjacent grooves can be formed in a roof shape so that the water
can
flow away to the grooves.
In further development of the invention, the opposite walls of the grooves may
run
downwards conically and the walls of the multiple pots may also run downwards
conically.
In this respect, those areas of the plate base located between two adjacent
grooves
are expediently formed In a roof shape.
Moreover, it is recommended that the culture piate should be formed in such a
way
that the multiple pots exhibit two flanges at the top which stick out on both
sides and
are supported in a holder groove.
It is particularly advantageous that several culture plates can be hooked
together in
order to form one longer row of culture plates.
Furthermore, the invention relates to a row of culture plates consisting of
several
culture plates for the rooting of young plants with rows arranged in parallel
with each
other in order to accommodate pots oriented downwards with holes in the base
of
the pots and with a surrounding edge enclosing the culture plate whereby the
culture
plates are hooked to each other.
In this respect, another thought of the invention is that the row of culture
plates
consists of one starting plate, at least one centre plate and one end plate.
3

CA 02283546 1999-09-24
In further development of the invention, it may be planned that the starting
plate is
trimmed at its end oriented towards the row of culture plates, that the end
plate is
also trimmed at its end directed towards the row of culture plates and that
the centre
plate is trimmed on both sides 1n such a way that the starting plate and the
end plate
can be hooked into the adjacent centre plate on one side and a centre plate
can be
hooked on both sides into the adjacent starting plate or into the adjacent end
plate
or into an adjacent centre plate.

The Invention is explained in greater detail below on the basis of a design
example
portrayed on the drawing. It shows
Fig. 1 an In-perspective representation of a row of culture plates, consisting
of
individuai culture plates hooked into each other,
Fig. 2 an in-perspective representation of the row of culture plates according
to Fig.
1 with individual culture plates arranged at a mutual distance apart and
Fig. 3 a longitudinal section through the row of culture plates along the line
III-III on
Figure 1 with one multiple pot.
The culture plate portrayed on the drawing is used for the rooting of young
plants.
Ttic row of culture plates portrayed on Figure 1 consists of one starting
plate 1, one
centre plate 2 and one end plate 3. The base of the row of culture plates
consists of
partial sections 4 to 11 which are formed in a roof shape and between which
grooves
12 to 18 are arranged. Moreover, a surrounding edge 19 to 26 is provided.
An example of the multiple pots is portrayed in the groove 13 - in this case,
consisting of 5 individual pots. An example with three individual pots is
portrayed in
groove 18. Multiple pots with 26 individual pots may be provided. The multiple
pots
27 and 28 have one flange 29 to 32 on each of the two sides with which they
are
supported in stepped shapes 33 and 34 at the top end of the walls forming the
grooves 18.
on Flgure 2, the row of culture plates portrayed on Figure 1 is portrayed when
the
Individual culture plates forming the row of culture plates are not hooked
into each
other. The same reference symbols are used here as on Figure 1. The starting
plate
1 is trimmed at its end facing the centre plate 2. Likewise, the centre plate
2 is
trimmed at its end facing the starting plate 1 whereby the two trimming
processes

CA 02283546 1999-09-24
are carried out in such a way that the outermost wall of the groove of the
starting
plate 1 projects over the outermost wall of the groove of the centre plate 2.
As a
result of this, both plates 1 and 2 are hooked with each other.
The end plate 3 is trimmed at its end 37 tacing the centre plate 2. Likewise,
the
centre plate 2 Is trimmed at its end 38 facing the end plate 3, i.e. in such a
way that
the wall 41 of the centre plate 2 projects over the wall 42 of the end plate
3. As a
result of this, both plates 2 and 3 are hooked with each other.
These conditions can be recognized easily on Figure 3. The wall 38 of the
starting
plate 1 projects over the wall 37 of the centre plate 2 whereby these walls
form a
part of the groove 14.
Multiple pots 27 are located in the groove 15 formed by the two walls 43 and
44. An
Intermediate space 47 is left between the bases 45 of the multiple pots 27 and
the
base 46 of the groove 15 so that the water emerging through the base opening
48 of
the multiple pots 27 can flow away in the lower area of the groove 15.
