Definitions
- Carrier system for cultivating plants with irrigation means for continuous liquid supply
- the invention relates to a carrier system for cultivating plants, in particular lettuce plants, the carrier system having a trough-shaped container with at least one substrate carrier arranged therein and a substrate arranged or arrangable in the substrate carrier for receiving the plants and/or for receiving seeds.
- a first intermediate space between the trough-shaped container and the at least one substrate carrier forms a first receiving area for receiving a liquid.
- a climatically sealed climate cell for cultivating plants indoors is also provided, with several carrier systems being arranged one above the other in at least two layers within the climate cell.
- DE 1 928 939 describes a climatic chamber for growing plants indoors.
- DE 1 778 624 describes a device for conditioning air for a climatic chamber.
- DE 10 2018 126 555 A1 describes a closed climate cell with movably arranged lighting platforms.
- DE 10 2016 121 126 B3 describes a climatically sealed climate cell for growing plants indoors.
- the object of the present invention is to provide a carrier system for cultivating plants, in particular lettuce plants, with optimum liquid supply for the plants or into the substrate being ensured.
- a carrier system for cultivating plants, in particular lettuce plants having a trough-shaped container with at least one substrate carrier arranged therein and a substrate arranged in or arrangable in the substrate carrier for receiving the plants and/or for receiving seeds.
- a first intermediate space between the trough-shaped container and the at least one substrate carrier forms a first receiving area for receiving a liquid.
- the carrier system has at least one irrigation means for the continuous transport of the liquid from the first receiving area to or into the substrate.
- the watering agent is arranged with a first end in the first receiving area and with an opposite end protrudes through a bottom opening in the substrate carrier and into the latter.
- the carrier system according to the invention is particularly suitable for plant cultivation indoors, for example in climatically closed climate cells, intended. Especially when cultivating indoors on several levels (vertical plant cultivation / vertical farming), the aim is to ensure that the plants are reared as automated and optimized as possible. It is also important to provide a rearing facility that saves resources as much as possible, i.e. also to optimize water consumption.
- the at least one watering means which is designed to continuously transport the liquid from the first receiving area to or into the substrate, regularly supplies plants optimally, but only with the required amount of liquid.
- the carrier system in the form of a trough-shaped container, is therefore used to hold one or more substrate carriers.
- the substrate carrier or carriers are arranged in the carrier system in such a way that a first gap is formed between the inner base of the carrier system and the base of the substrate carrier.
- This first intermediate space forms a first receiving area for receiving the liquid, in particular for receiving water.
- the water provided for watering the plants is thus only introduced into this first intermediate space.
- the forwarding of the liquid to or into the substrate is then carried out continuously, essentially automatically, by the at least one watering means. This ensures a constant and demand-oriented supply of liquid to or into the substrate.
- a carrier system and a substrate carrier Preferably, several or particularly preferably a large number of watering means are provided for a carrier system and a substrate carrier. This not only ensures a steady and continuous liquid supply to or into the substrate, but also an evenly distributed liquid supply.
- the irrigation medium is designed to utilize the capillary effect.
- the irrigating means extends up from the first receiving area and into the substrate support. In the first receiving area, one end of the watering agent thus protrudes into the liquid, for example into the water. The opposite end protrudes through the bottom opening into the substrate carrier. In this case, it can be arranged in the substrate carrier below the substrate or protrude into the substrate.
- the bottom opening in the substrate carrier is designed as an opening through the bottom of the substrate carrier, for example in the form of a hole.
- any suitable substrate can be or will be arranged in the substrate carrier.
- a foil and/or mat and/or membrane, in particular a hydro-membrane could be provided.
- the substrate is preferably designed as a substrate rich in minerals and nutrients.
- the substrate is particularly preferably designed as a loamy soil substrate.
- a Bestponic substrate could be provided.
- the watering means is preferably elongate and in particular in the form of a cord or strip.
- the irrigation means can have the form of a piece of rope, a cord or a cord.
- the irrigating agent could also have or consist of a fleece.
- the length of the irrigation medium depends on the respective situation or application adaptable. In particular, the length of the
- Irrigation agent may also depend on the choice of substrate.
- the watering agent has or consists of wool, cotton, nylon and/or glass fiber.
- the irrigating agent could also have further or other materials which have good absorbent properties.
- the substrate carrier apart from the bottom opening or the bottom openings through which the watering agent or means is or are passed, has no further openings on an underside of the substrate carrier, which are located below a liquid level of the liquid in the first intermediate space. This ensures that the liquid is only supplied via the irrigation means, which protrude through the floor openings provided for this purpose. As a result, the liquid in the first intermediate space below the substrate carrier does not penetrate directly through the bottom openings or additional openings into the substrate carrier.
- the substrate carrier preferably has feet with which it stands on an inner base of the trough-shaped container.
- the feet thus serve as spacers, also for forming the first intermediate space.
- the feet serve to increase the stability of the substrate carrier.
- suitable feet in particular by providing a large number of feet, it can be ensured that the base of the substrate carrier does not sag or arch downwards even under load.
- the distance between the inner floor of the trough-shaped container and the floor of the substrate carrier and thereby the height of the first gap is essentially constant in each area.
- spacers could also be arranged on the inside floor of the trough-shaped container.
- the distance between the inner bottom of the trough-shaped container and the bottom of the substrate carrier and thus the height of the first gap is at least partially and/or partially higher than the liquid level of the liquid in the first gap.
- the bottom of the substrate carrier preferably does not lie on the liquid, at least not in every area.
- ventilation openings are preferably arranged in the substrate carrier to aerate the roots. These ventilation openings can be designed as holes and/or as perforations in the base of the substrate carrier.
- the bottom of the substrate carrier preferably has inwardly protruding indentations in sections or recesses viewed from the outside. In these areas, the first gap is therefore greater than in adjacent areas.
- the bottom openings, through which the watering means are passed, are preferably arranged in these indentations. Furthermore, it is preferably provided that the ventilation openings are arranged in these indentations. This ensures that these are above the liquid level. Alternatively, the height of the feet may be designed such that the first gap is located above the liquid level in each area.
- the trough-shaped container preferably has at least two layers, namely an outer layer and an inner layer. In this case, preferably not only a double-layer base is provided, but also double-layer sides are provided for the trough-shaped container. The layers can be permanently or detachably connected to one another.
- the outer layer is preferably substantially rigid and structurally formed as a support.
- the outer layer thus serves to ensure the stability of the trough-shaped container.
- the outer layer has or consists of metal, in particular aluminum.
- metal in particular aluminum
- the inner layer preferably forms the liquid-carrying layer of the trough-shaped container.
- the liquid is located on the inner layer and not between the outer and inner layers.
- the inner layer forms the inner base of the trough-shaped container.
- the inner layer preferably has plastic or consists entirely of plastic.
- the outer layer and the inner layer are preferably designed as separate pans placed one inside the other.
- the inner layer can be designed as a type of inner pan and the outer layer as a type of outer pan, with the inner pan simply being placed in the outer pan and easily removed from it, for example for cleaning or harvesting.
- the outer layer is double-walled, forming a second intermediate space. The distance between the two walls of the double-walled outer layer and thus the height of the second intermediate space is essentially the same in each area.
- the trough-shaped container preferably has a double-walled outer layer at least in the bottom area.
- the outer layer has a first wall and a second wall arranged at a distance from the first wall.
- the inner layer of the trough-shaped container is then arranged, for example, on the first wall of the outer layer.
- the side walls of the outer layer of the trough-shaped container can also be double-walled.
- a second receiving area for receiving a further liquid is formed by the second intermediate space, the first receiving area and the second receiving area being fluidically separated from one another.
- the further liquid can and is preferably also water.
- the trough-shaped container preferably has two liquid chambers.
- a liquid chamber extends between the inner layer of the trough-shaped container and the underside of the substrate carrier. This liquid chamber is therefore not completely closed around the circumference.
- This liquid chamber can be designed to be open, especially in the transition or edge area between the trough-shaped container or its outside and the substrate carrier.
- the second liquid chamber extends between the two walls of the double-walled outer layer of the trough-shaped container.
- lamps for illuminating a plant layer that can be arranged or is arranged under the carrier system are arranged on an underside of the double-walled outer layer of the trough-shaped container, with the additional liquid in the second receiving area serving to cool the lamps.
- the lighting means can be distributed on the outside of the base or the double-walled outer layer of the trough-shaped container.
- the further liquid is preferably a coolant for cooling the electronics or the lighting means and thus particularly preferably water.
- the outer wall of the double-sided outer layer of the trough-shaped container has good thermal conductivity. At least this wall is preferably made of metal, for example aluminum. Very particularly preferably, both walls of the double-walled outer layer of the trough-shaped container are made of metal, preferably aluminum.
- a climatically sealed climate cell for cultivating plants indoors is also provided, with several carrier systems being arranged one above the other in at least two layers within the climate cell.
- the carrier systems are designed according to the invention as described above.
- the climatically sealed climate cell preferably has regulating means for regulating a temperature and/or a relative humidity and/or a carbon dioxide content and/or an air speed and/or an irrigation duration and/or a Lighting duration and / or lighting intensity within the climate cell.
