  • Such an angle is not well suited for growing plants with large vegetation such as lettuces, or
  • the solution for those skilled in the art, consists of cultivation on horizontal flat supports, which allow sufficient spacing of the culture supports in order to
  • the present invention relates, in its most general sense, to an above-ground cultivation module constituted by a support.

  • the openings not occupied by a culture support are closed by stoppers.
  • the invention also relates to an above-ground cultivation installation comprising a plurality of above-ground cultivation module constituted by a support having two inclined panels connected by an edge whose median planes form with the horizontal plane an angle between 30 and 40 ° and in that said panels constitute a tight barrier between the root space and the stem space, and are crossed by a plurality of openings for maintaining a culture support or a closure plug for the openings not occupied by a growing medium, said modules being juxtaposed to form a corrugated surface separating the root space from the stem space, said installation

  • FIG. 3 shows a perspective view of an alternative embodiment of an installation according to the invention
  • Figure 6 shows a three-quarter view below of a culture medium
  • Figure 7 shows a top view of a
  • Figure 8 shows a top view of a detail of the misting assembly
  • FIG. 9 shows a schematic overview of the support and the misting system. General description of the installation
  • FIG. 1 represents a general view of an installation according to a first example of implementation of the invention.
  • the installation comprises a frame (1) intended to raise the growing area to a height facilitating handling by a standing operator, and freeing up a lower space for the circulation of misting robots, in the case of growing in aeroponics.
  • the culture is carried out on modules (2 to 5) of prismatic shape, each having a front inclined panel (6) and a rear inclined panel (7) and closing side faces (8).
  • These panels (6, 7) are in the example described without limitation plan and has circular lights for the insertion of culture media of a salad, or a closure cap for the lights not used, in order to provide a barrier between the lower space, subject to misting of the roots, and the upper space, subject to a contribution of natural and / or artificial light energy.
  • the modules (2 to 5) made of material can be produced by thermoforming or folding of a sheet of plastic material or by folding of a metal sheet, for example an aluminum sheet.
  • the lights for the insertion of the culture supports are aligned horizontally with a constant pitch corresponding to the nominal section of a salad at maturity.
  • the consecutive lines are shifted by half a step to form a matrix of lights arranged in anyone, making it possible to optimize the space available for the
  • the optimal distance between salads is between 20 and 32 cm. It can go down to 10 cm for aromatic, medicinal plants, or certain fruits and vegetables.
  • the two panels (6, 7) each form with the horizontal plane an angle of 36 °, respectively + 36 ° and -36 °, and an angle at the top of 108 °.
  • the modules are prepared in an area of
  • upstream preparation (10) where they are deposited to be loaded with the culture supports, or already loaded with the
  • the determining factors for production include temperature and radiation, and the intensity of lighting.
  • the sensitivity of lettuce to acidity is an important factor. It is therefore essential to regulate and control the acidity level of the nutrient solution.
  • a romaine lettuce takes between 40 and 100 days to reach its ideal size after planting, and growing in hydroponics or aeroponics can reduce this period between 25 and 50 days.
  • the nutrient solution is
  • the intensity is between 80 and 300 micromol / m2 / s.
  • the nutrient supply by misting or by soaking the roots in a reserve has an optimum pH of 5.2 to 6.4), and a salinity with resistivity of between 700 and 2200 s / cm / cm2. This level of acidity can be obtained by adding nitric acid (or phosphoric acid) in small amounts in the nutrient solution, until reaching the desired pH level.
  • the minerals that the plant consumes in large quantities include nitrogen, phosphorus, potassium, calcium. Plants need other minerals, but in much smaller quantities. These are trace elements (from the Greek oligos, small, few in number) composed of iron, magnesium, sulfur, manganese, zinc, boron, copper, molybdenum, chlorine and nickel.
  • Lettuces are known to be vegetables that need water but not a lot of nutrients.
  • An example of a nutrient solution is constituted by (in mol m_3)
  • the culture supports have a housing whose bottom has a light of increasing width from the center to the periphery, and in that each of said
  • culture media is movable relative to the cut in which it is inserted, in a direction corresponding to the median longitudinal axis of said light between a closed position of said light and an open position.
  • said culture support is a molded part having a planar blade of a section
  • said blade having an opening under which said blade is extended by a housing having said lumen of increasing width, said flat blade and said housing defining a hollow space whose height corresponds to the thickness of said reception area.
  • FIG. 2 shows a schematic perspective view in partial section of another form of module.
  • the module consists of a thermoformed form having two inclined panels (6, 7) forming at the top an angle of about 108 °.
  • These panels have hollow protuberances (14, 15, 18) raising the lights (24, 25) intended to receive the culture support in order to allow the salads (represented in FIG. 2 diagrammatically with an ovoid shape) to grow with a vertical stem and a horizontal expansion of the foliage.
  • the openings (24, 25) are thus positioned in tiers and staggered to optimize the horizontal density and the space available for the growth of the salad.
  • thermoformed panels (6, 7) are extended by a horizontal strip (16, 17) having fixing holes (20, 21).
  • FIG. 3 represents an alternative embodiment in which each culture module (2, 3, 4, 5) is formed by a shell with four inclined sides, including two main faces (6,
  • Each culture module (2, 3, 4, 5) rests on a hollow tank (30), having a curved bottom (31) to form two lateral channels (32, 33).
  • This tank contains the liquid
  • the trays rest on longitudinal rails (34, 35) placed on the ground, which therefore does not require earthworks.
  • the tanks (30) have fluid connections on the front and rear faces to allow the transmission of the nutritive fluid over the entire series of aligned tanks.
  • Figures 4 and 5 respectively represent a plane support and a plug.
  • the plan support is
  • the central part has radial incisions (49) defining flexible petals converging towards a central well (48) intended to receive a seed in a hollow area (47). During germination, the roots are
  • FIGS. 6 to 9 relate to an alternative embodiment of an aeroponic culture system, with a series of modules (2 to 5) of prismatic shape, each having a front inclined panel (6) and a rear inclined panel (7) and lateral closing faces (8).
  • Each of the prismatic modules (2 to 5) is formed by a folded sheet having a top strip (51) also having slots for the insertion of a culture element, and two folded strips (56, 57) ensuring the rigidity of the support.
  • the installation includes a frame (1) intended to raise the growing area to a height facilitating manipulations by a standing operator, and freeing up a lower space for the circulation of misting robots, in the case of culture in aeroponics.
  • the misting robot consists of a misting head (60) supported by a trellis (65)
  • the trellis structure (65) is fixed at each end to a chassis (66) supporting wheels (67 to 69) driven by motors (77, 78).
