  • vessels 1 a-11 are coupled in series by means of pipings or tubings 30, and the aqueous solution is pumped by the pump 32 in the tubings 30 with a flow direction indicated by the straight arrows of figure 4.

  • a suitable carrier or support system for carrying the vessels 1 a-11 may be used, although not illustrated in figure 4.
  • the vessels 1 a-11 are positioned in four rows with three vessels 1 in each row. Nutrients or other agents may be added the system to the tank 36, or to the tubings 30.
  • a pump 32 may be used to pump the fluid, although the system would also function with water pressurized by other means such as by originating from a tank or other container holding water at a higher altitude than the vessels. As the water by such means are circulated through the vessel(s) the soil would be soaked, at least the lower portion of the soil, which would give the plants or seeds access to the water. It may be beneficial and possible with the vessels of the invention, particularly if the area available for growing is limited or scarce, to position a plurality of vessels one on top of the other, as illustrated in figure 4, with suitable space between them, which space may be provided by supporting the vessels in suitable racks or shelves or any other such suitable means. For such a positioning the user would realize that vessels 1 with a V-shaped cross- section further benefits from that the vessel on top of the other does not shade the below vessel(s) as much as a vessel with rectangular cross-section might.
  • Advantages with the vessel and system include irrigation from the bottom of the vessel and the flow-through of aqueous solution, which minimizes losses of aqueous solution and any therein contained nutrients.
  • Any aqueous solution not taken up by the cultivation media or plants in a vessel may, for example, be recycled to other vessels or to a aqueous solution containing tank.
  • This is in contrast to for example systems using irrigation by means of drop hoses with which systems there is a risk of either over-feeding the plants with water or nutrients and resulting drainage of nutrients and water from the system to waste, or the risk of under irrigation of the plants such as, for example, if the dropwise added water to a great extent is evaporated from the surface to which it is added before being contacted with roots of the cultivated plants.
  • concentration of nutrients in the aqueous solution may be altered and presented to the vessel, at any time, such as, for example, by adding nutrients to a feed line upstream the vessel in order to increase the amount of nutrients fed to the vessel.
  • water may be added to the feed line upstream the vessel in order to decrease the concentration of nutrients in the aqueous solution and thus decrease the amount of nutrients fed to the vessel.
  • Aqueous solution may further be recycled through the vessel(s) until the nutrient uptake by plants cultivated in the vessels have decreased the concentration of nutrients in the aqueous solution to a point where it is determined that an addition of nutrients to the recirculated aqueous solution is deemed appropriate.
  • Water may also be added to the recirculated aqueous solution, for example for compensating for water uptake by the plants or any loss of water. It is further realized that not only nutrients may be added to the aqueous solution, but also, any compound, formulation or agent suitable for the cultivation of the plants. Further, low pressure may be used for circulating the aqueous solution through the irrigation compartment(s) of one or more vessels, as one result of the inlet opening and the outlet opening may be kept sufficiently large not to provide a large pressure drop, although it is possible to use higher pressure, for example, if the level of the surface of the aqueous solution is elevated to the cultivation compartment by restricting the outlet.

Abstract

Récipient utilisable dans la culture de plantes. Le récipient comprend une première paroi latérale, et une deuxième paroi latérale opposée, une troisième paroi latérale et une quatrième paroi latérale opposée, une partie inférieure, et un élément cloison conçu pour séparer le récipient en un compartiment de culture supérieure contenant un milieu de culture et un compartiment d'irrigation inférieure contenant une solution aqueuse. En outre, l'élément cloison est conçu pour permettre le passage de la solution aqueuse entre le compartiment d'irrigation et le compartiment de culture. Le passage de l'eau s'effectue par des ouvertures d'irrigation pratiquées dans l'élément cloison et/ou par au moins une ouverture d'irrigation formée par un espace entre l'élément cloison et l'une quelconque des première, deuxième, troisième et quatrième parois latérales. Le compartiment d'irrigation comporte une ouverture d'entrée pour l'introduction de la solution aqueuse dans le compartiment d'irrigation, et une ouverture de sortie assurant la sortie de la solution aqueuse du compartiment d'irrigation. Le récipient permet ainsi l'écoulement de la solution aqueuse à travers le compartiment d'irrigation et son passage dans le compartiment de culture. L'invention concerne également un système utilisable pour la culture de plantes.
