Definitions

• the present invention is in the field of equipment used in agriculture and relates to a composite covering for growing plants above ground capable of receiving a culture substrate.
• State-of-the-art is known of culture installations using metal culture tanks suspended to the frame of a greenhouse by slings. These culture tanks receive culture substrates in the form of bagged breads or in the form of appropriate bulk material intended to receive the plants to be cultivated. Such facilities are also equipped with transport pipes intended to bring water and nutrients to different plants. They are also equipped with pipes for the evacuation of effluents.
• the present invention has the effect of solving the drawbacks mentioned above by proposing a composite covering for the above-ground cultivation of plants, able to receive and maintain a culture substrate and capable of draining liquid flows.
• the composite covering according to the present invention for the above-ground cultivation of plants is essentially characterized in that it comprises:
• a first flexible wall in the form of a rectangular strip having a longitudinal central zone provided with through perforations, designed to be arranged as a chute, and
• a second flexible, sealed, flexible wall extending under the perforated region of the longitudinal central zone of the first wall and forming a gutter for discharging liquid effluents, the central zone of the first wall being designed to receive a substrate of culture.
• Such a tarpaulin advantageously replaces the heavy installations that are those constituted by metal bins suspended above the ground. At the end of the season this tarpaulin, after washing can be folded on itself and stored in a reduced storage space which is still a advantage over known culture tanks which generally have a length of a few meters.
• the composite cover can be suspended by the longitudinal edges of its first wall to a suitable support structure. It can also be affixed to a mound of earth or other material having a planar upper surface or table, from which is dug a first longitudinal channel intended to accommodate the central zone of the first wall, the second wall in the form of a gutter being disposed in a throat
• the through perforations that comprise the central zone of the first wall will be of a sufficiently large diameter to allow the flow of liquid effluents to the gutter formed by the second wall, but of sufficiently small diameter to oppose the passage to this gutter of the culture substrate.
• the perforations are of a relatively large diameter and the central zone of the first wall is covered with a veil permeable to the filter liquid.
• This arrangement opposes the passage of the culture substrate to the gutter that forms the second wall.
• the longitudinal edges of the first wall each have a suspension hem to a supporting structure.
• the longitudinal edges of the first wall constituting the composite sheet are each equipped with a ballast means.
• a ballast means Such an arrangement allows the tensioning of the first wall when the tarpaulin is installed on a mound or other similar support.
• the composite cover is provided with a cover and protection flap formed by a flexible wall of rectangular shape coming to cover at least the central zone of the first wall. Such an arrangement allows the recovery of the culture substrate.
• the cover and protection flap is provided with through holes through which the plants pass. So the plants can grow without their leaf stage or fruiting stage coming into contact with the culture substrate or with the earth mound in the case where the composite cover is associated with such a butte.
• the cover and protection flap is provided in at least one of the longitudinal edges of a ballast means. Such an arrangement allows the tensioning of the cover flap on the first wall.
• the flap by its other longitudinal edge is fixed by welding to the first wall.
• the covering flap has, according to each of its longitudinal edges, a ballast means.

• the second gutter wall is fixed by its two longitudinal edges to the first wall on either side of the perforated region of the central zone this first wall.

• the lines of attachment of the wall 2 to the wall 1 are continuous and are formed on either side of the perforated region of longitudinal central zone 10 of the wall 1.
• the distance between the two fastening lines is less than the width of the second wall so that the second wall can form under the perforated region of the first wall 1, a long pouch forming effluent discharge gutter.

It can be seen that this culture installation is formed of several earth masses 100, longitudinal, parallel, separated from each other by traffic corridors. These earth mounds 100 form longiform supports of frustoconical cross section and each have, in the upper part, a flat horizontal table face. Each hill 100 also has two inclined lateral flanks. Each earth butt 100 is provided with a longitudinal channel 1 10 dug from the flat upper face and a longitudinal chute 120 dug from the bottom of the channel 1 10.
