Description

The invention relates to a plant container according to the preamble of the claim.

There are already known plant containers of the type mentioned in the form of the usual hotbeds (See, for example, »Basics and advances in gardening and Weinbau «, booklet 41, pages 34-41; »Self-sufficiency from the garden« by John Seymour, Pages 95/96).

It is important for the convertible material to be converted at sufficient speed intensive ventilation. However, this is insufficient with the known hotbeds, so that there the decomposable material under the humus layer is only partially or incompletely used.

From DE-OS 27 29 379 a greenhouse system is known in which sowrhl Kor post containers and plant containers are set up in two groups. The air trapped in the greenhouse is heated by intensive ventilation of each compost container in the greenhouse system, with ventilation partly from below, but mainly from the side, which in turn transfers its heat indirectly to the plant container. Such a system is too expensive for allotment gardening purposes and does not have a fully satisfactory effect for certain types of crops, since the heat transfer through the fluid air is not as effective as a direct heat transfer from the compost to the humus layer, analogous to the known hotbeds discussed above where there is direct heat transfer, but with insufficient ventilation of the compost. In the case of the greenhouse system under consideration, the use of energy is also not optimal, because the u
A substantial proportion of the air heated in the compost bin reaches the greenhouse roof by convection, where it gives off its heat to the outside ambient air.

From DE-OS 27 35 288 a greenhouse system of a similar type to that according to DE-OS 27 29 379 is known, but instead of the compost bins, underground reaction pipes are provided, in which compost is rotted through ventilation. The heat developed in this way becomes only one small part immediately above the reaction ^ plant containers sunk into the ground, mainly but indirectly by heating the in the air contained in the greenhouse system,

There are also pure compost containers according to DE ^ PS 13 01828, 20 07 755, 25 42 677, according to DE ^ ÖS 24 11360 And the DE-GM 75 14 686 known, in which the compost by intensive aeration is subject to rapid rotting.

The object of the invention is based on the known at the outset dealt with in the first place Hotbeds the creation of a plant container with, in contrast, improved ventilation and increased The rate of rotting of what is below the humus layer or other substrate layer rotable material with a simple structure

ίο which an application especially for allotment gardeners Purposes. This is achieved through the characterizing features of the patent claim.

In contrast to the known hotbeds, the air-permeable one provided according to the invention Formation of the container bottom achieves a substantial increase in the rate of rotting Compared to the larger greenhouse systems discussed above with separate compost and plant containers there is the advantage of direct heat transfer from the rotting material the humus layer or other nutrient-like substrate layer and therefore an optimal use of heat without significant heat loss through convection. With a simple structure (use of a common Container for the rotting material and the humus layer) is an optimal direct heat transfer to the humus layer and thus an optimal utilization of the rotting material thermal energy contained. This in turn results in particular in an application of the explained principle for allotment gardening purposes with reasonable effort.

The invention is explained in more detail below with reference to the drawing. It shows

1 shows a first embodiment of a plant container according to the invention in a side view,
FIG. 2 shows the plant container from FIG. 1 in an end view, FIG. 3 shows a section along the line IH-III from FIG. 1, F i g. 4 shows a section along the line IV-IV from FIG. 3 in an enlarged partial representation,

F i g. 5 one opposite FIG. 1-4 modified Plant container in a representation analogous to FIG. 2.

On a floor space is by means of underlying spacer elements 1 in the form of bars or slats A plant container 2 with ventilated side walls and a ventilated container base is set up. The container 2 can expediently be made of galvanized welded wire mesh. In the embodiment according to Fi g. 1 -3 is the container 2 with a greenhouse housing 3 firmly connected and set up for access from the outside. The greenhouse housing 3 consists of the usual Made from a metal strip framework into which panes of glass are inserted. On the gable roof surfaces Ventilation flaps 4 can be provided in the greenhouse housing.

As best seen in Fig. 3, the container 2 has a U-shaped plan and is about a door 5, which is hinged to both the greenhouse housing 3 and the container 2, from the outside walkable.

As can best be seen from FIG. 4 results, see in the container 2 decayable material 6, on which a thin humus or other nutrient-like substrate layer 7 is applied, the thickness of the layer 7 is

for example in the order of about 10 cm is used with cultivated plants 8, for example lettuce, planted. It is essential that the Treibhäüsgehäuse 3 extends down at least to the layer 7 in the

Representation according to Figure 4 extends the lower edge of the Greenhouse housing 3 a little further down, because it must be taken into account that the rotable good 6 sets over time.

In a modification of the exemplary embodiment according to FIG. 1-3 and in particular for the layout of FIG. 3, the layout of a smaller plant container 2 can also be L-shaped, with the layout parts to the right of a cutting line SL to be thought of as not being present. The plan dimensions of the container 2 are expediently chosen so large that all plan area parts can be reached by hand from an accessible area 9

can.

In the embodiment of Figure 5 are Components analogous to those in FIGS. 1 to 4 are provided with the same reference numerals. On an inaccessible A greenhouse housing 3 is to be placed on plant container 2 in a detachable manner from above in the direction of an arrow P /. Of the Container 2 is charged in an analogous manner as shown in FIG. In contrast to the exemplary embodiment according to FIG. 1 - 3 is each time a work process is carried out in or on the Container 2 to remove the greenhouse housing 3 and to put it back on after the work process is finished.

Claims (1)

Claim: Plant containers with a filling made of decayable material and one immediately above it located humus layer or some other nutrient-like substrate layer, which for planting is intended with crops, and with a placed on the container, at least up to greenhouse housing reaching down to the humus or substrate layer, characterized in that that the container bottom is made air-permeable and by means of spacer elements (1) of is spaced from a footprint.
