La présente invention est du domaine des matériels utilisés en agriculture et concerne une bâche composite pour la culture des plantes hors sol apte à recevoir un substrat de culture.  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.
État de la technique antérieure. State of the art
On connaît de l'état de la technique des installations de culture mettant en œuvre des bacs de culture métalliques suspendus à l'ossature d'une serre par des élingues. Ces bacs de culture reçoivent des substrats de culture sous forme de pains ensachés ou sous forme de matériau approprié en vrac prévus pour recevoir les plantes à cultiver. De telles installations sont de plus équipées de conduites de transport prévues pour amener l'eau et les substances nutritives aux différents végétaux. Elles sont également équipées de conduits pour l'évacuation des effluents.  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.
L'inconvénient de telles installations est principalement leur coût.  The disadvantage of such facilities is mainly their cost.
Exposé de l'invention.  Presentation of the invention.
La présente invention a pour effet de résoudre les inconvénients précédemment cités en proposant une bâche composite pour la culture hors sol des plantes, apte à recevoir et maintenir un substrat de culture et apte à drainer les écoulements liquides.  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.
A cet effet la bâche composite selon la présente invention, pour la culture hors sol des plantes se caractérise essentiellement en ce qu'elle comprend : For this purpose, the composite covering according to the present invention for the above-ground cultivation of plants is essentially characterized in that it comprises:
- une première paroi souple sous forme de bande rectangulaire dotée d'une zone centrale longitudinale pourvue de perforations traversantes, prévue pour être agencée en goulotte et, 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
- une second paroi souple rectangulaire, étanche, s'étendant sous la région perforée de la zone centrale longitudinale de la première paroi et formant une gouttière d'évacuation des effluents liquides, la zone centrale de la première paroi étant prévue pour recevoir un substrat de culture.  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.
Une telle bâche remplace avantageusement les installations lourdes que sont celles constituées par des bacs métalliques suspendus au dessus du sol. En fin de saison cette bâche de culture, après lavage peut être repliée sur elle même et rangée dans un espace de stockage réduit ce qui est encore un avantage par rapport aux bacs de cultures connus qui présentent généralement une longueur de quelques mètres. 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.
La bâche composite peut être suspendue par les bordures longitudinales de sa première paroi à une structure support appropriée. Elle peut aussi être apposée sur une butte de terre ou autre matériau comportant une face supérieure plane ou table, depuis laquelle est creusé un premier canal longitudinal prévu pour accueillir la zone centrale de la première paroi, la seconde paroi sous forme de gouttière étant disposée dans une gorge  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
longitudinale creusée dans la butte depuis le fond du canal longitudinal. longitudinal dug into the hillock from the bottom of the longitudinal canal.
Les perforations traversantes que comporte la zone centrale de la première paroi seront d'un diamètre suffisamment important pour permettre l'écoulement des effluents liquides vers la gouttière formée par la seconde paroi, mais de diamètre suffisamment faible pour s'opposer au passage vers cette gouttière du substrat de culture.  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.
Alternativement, selon une autre caractéristique de l'invention, les perforations sont d'un diamètre relativement important et la zone centrale de la première paroi est recouverte d'un voile perméable au liquide formant filtre. Alternatively, according to another characteristic of the invention, 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.
Cette disposition s'oppose au passage du substrat de culture vers la gouttière que forme la seconde paroi. This arrangement opposes the passage of the culture substrate to the gutter that forms the second wall.
Selon une autre caractéristique de la bâche composite selon l'invention, les bordures longitudinales de la première paroi sont dotées chacune d'un ourlet de suspension à une structure porteuse.  According to another characteristic of the composite covering according to the invention, the longitudinal edges of the first wall each have a suspension hem to a supporting structure.
Alternativement, selon une autre caractéristique de l'invention, les bordures longitudinales de la première paroi constitutive de la bâche composite sont équipées chacune d'un moyen de lestage. Une telle disposition permet la mise en tension de la première paroi lorsque la bâche est installée sur une butte de terre ou autre support analogue.  Alternatively, according to another characteristic of the invention, the longitudinal edges of the first wall constituting the composite sheet are each equipped with 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.
Selon une autre caractéristique de l'invention, la bâche composite est dotée d'un volet de recouvrement et de protection formé par une paroi souple de forme rectangulaire venant recouvrir au moins la zone centrale de la première paroi. Une telle disposition permet le recouvrement du substrat de culture.  According to another characteristic of the invention, 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.
Selon une autre caractéristique de l'invention, le volet de recouvrement et de protection est doté de perçages traversants de passage des plantes. Ainsi les plantes peuvent croître sans que leur étage foliaire ou leur étage fructifère n'entre en contact avec le substrat de culture ou encore avec la butte de terre dans le cas où la bâche composite est associée à une telle butte. According to another characteristic of the invention, 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.
Selon une autre caractéristique de l'invention, le volet de recouvrement et de protection est doté selon au moins l'une de des bordures longitudinales d'un moyen de lestage. Une telle disposition permet la mise en tension du volet de recouvrement sur la première paroi.  According to another characteristic of the invention, 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.
Selon une autre caractéristique de l'invention, le volet par son autre bordure longitudinale est fixé par soudage à la première paroi.  According to another characteristic of the invention, the flap by its other longitudinal edge is fixed by welding to the first wall.
Alternativement, selon une autre caractéristique de l'invention, le volet de recouvrement présente selon chacune de ses bordures longitudinales un moyen de lestage. Selon cette variante d'exécution, le volet de recouvrement n'est pas fixé à la première paroi.  Alternatively, according to another characteristic of the invention, the covering flap has, according to each of its longitudinal edges, a ballast means. According to this variant embodiment, the cover flap is not fixed to the first wall.
Selon une autre caractéristique de l'invention, la deuxième paroi formant gouttière est fixée par ses deux bordures longitudinales à la première paroi de part et d'autre de la région perforée de la zone centrale cette première paroi.  According to another characteristic of the invention, 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.

Meilleure manière de réaliser l'invention. Best way to realize the invention.
On observe sur les figures une bâche composite comportant une première paroi souple 1 en matière synthétique, et une deuxième paroi souple 2 imperméable formant gouttière sous la première paroi souple 1 .  In the figures, a composite sheet is seen having a first flexible wall 1 of synthetic material, and a second flexible flexible wall 2 forming a channel under the first flexible wall 1.
La première paroi souple 1 , se présente sous la forme d'une bande rectangulaire en matière synthétique imperméable, par exemple en polyéthylène de couleur noire ou blanche selon le type de culture envisagée et selon qu'il est souhaitable d'absorber la chaleur ou la réfléchir. Cette première paroi 1 pourra présenter une face de couleur noire et une face de couleur blanche. The first flexible wall 1, is in the form of a rectangular strip of impermeable synthetic material, for example black or white polyethylene according to the type of culture envisaged and as it is desirable to absorb heat or reflect it. This first wall 1 may have a black face and a white face.
La première paroi 1 est dotée d'une zone centrale longitudinale 10 prévue pour être agencée en goulotte et prévue pour recevoir un substrat de culture tel que des pains de culture ensachés ou des substrats de culture en vrac, connus en soi. Cette zone centrale 10 est pourvue de perforations traversantes 1 1 de formes circulaires par exemple, agencées en lignes parallèles à l'axe longitudinal de cette première paroi. La région perforée n'occupe qu'une partie de la largeur de la zone centrale 10 de sorte que cette dernière de part et d'autre de la région perforée présente deux régions latérales, longitudinales étanches. La région perforée est prévue pour constituer le fond de la goulotte que formera  The first wall 1 is provided with a central longitudinal zone 10 designed to be arranged in a chute and designed to receive a culture substrate such as bagged culture loaves or bulk culture substrates, known per se. This central zone 10 is provided with through perforations 11 of circular shapes, for example, arranged in lines parallel to the longitudinal axis of this first wall. The perforated region occupies only part of the width of the central zone 10 so that the latter on either side of the perforated region has two sealed longitudinal side regions. The perforated region is intended to constitute the bottom of the chute that will form
ultérieurement la zone centrale 10 de la première paroi 1 tandis que les deux régions latérales constitueront les flancs latéraux de cette goulotte. subsequently the central zone 10 of the first wall 1 while the two lateral regions will form the lateral flanks of this chute.
Chaque bordure longitudinale 12 de cette première paroi, selon une première forme de réalisation, est dotée d'un moyen de lestage constitué par exemple par un ourlet formé le long de la dite bordure et d'une masse de lestage disposée dans l'ourlet. Cette masse de lestage pourra être constituée par de la terre, par du sable ou autre matière pouvant constituer un lest.  Each longitudinal edge 12 of this first wall, according to a first embodiment, is provided with a weighting means consisting for example of a hem formed along the said edge and a ballast mass disposed in the hem. This ballast mass may consist of soil, sand or other material that may constitute a ballast.
Selon une variante de réalisation, chaque bordure longitudinale 12 de la première paroi souple 1 est agencée en ourlet de suspension.  According to an alternative embodiment, each longitudinal edge 12 of the first flexible wall 1 is arranged in suspension hem.
La deuxième paroi souple 2 imperméable, par exemple de couleur noire, se présente sous la forme d'une bande rectangulaire en matière synthétique.

Preferably this second wall 2 is fixed by its two borders
longitudinales, par exemple par soudage, collage ou autre à la première paroi et plus particulièrement à la zone centrale 10 de cette dernière. Les lignes de fixation de la paroi 2 à la paroi 1 sont continues et sont formées de part et d'autre de la région perforée de zone centrale longitudinale 10 de la paroi 1 . La distance entre les deux lignes de fixation est inférieure à la largeur de la deuxième paroi de façon que cette deuxième paroi puisse former sous la région perforée de la première paroi 1 , une poche longiforme formant gouttière d'évacuation des effluents. longitudinal, for example by welding, bonding or other to the first wall and more particularly to the central zone 10 of the latter. 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.
Avantageusement la zone centrale 10 de la première paroi 1 est recouverte d'un voile 4 formant un filtre perméable aux liquides. Cette disposition à pour but de retenir le substrat de culture et éviter son écoulement vers la gouttière formée par la paroi 2. Avantageusement ce voile n'est pas fixé de manière permanente à la première paroi mais éventuellement par des moyens d'attache rapide qui peuvent être du type de ceux connus sous le nom Advantageously, the central zone 10 of the first wall 1 is covered with a web 4 forming a liquid-permeable filter. This provision intended to retain the culture substrate and prevent its flow to the gutter formed by the wall 2. Advantageously this veil is not permanently attached to the first wall but possibly by means of quick attachment which can be of the type of those known as
commercial de Velcro. De telles dispositions permettent le retrait aisé du voile 4 et du substrat de culture supporté par ce dernier. Alternativement, ce voile sera simplement posé sur le fond de la goulotte formée par la zone centrale 10 de la première paroi, sans usage de moyens de fixation. commercial Velcro. Such arrangements allow the easy removal of the veil 4 and the culture substrate supported by the latter. Alternatively, this veil will simply be placed on the bottom of the chute formed by the central zone 10 of the first wall, without the use of fixing means.
De préférence, la bâche composite sur la première paroi 1 comporte un volet de recouvrement 3 et de protection formé par une bande rectangulaire imperméable, de préférence en matière synthétique. Ce volet de recouvrement peut être de couleur noire ou blanche ou présenter une face noire et une face blanche pour les raisons précédemment évoquées.  Preferably, the composite cover on the first wall 1 comprises a covering flap 3 and protection formed by an impermeable rectangular strip, preferably of synthetic material. This cover flap may be black or white or have a black face and a white face for the reasons mentioned above.
Selon une forme préférée de réalisation le volet de recouvrement 3 est fixé par une de ses bordures longitudinales 30 à la première paroi 1 et ce entre la zone centrale 10 de cette première paroi 1 et l'une des bordures longitudinales de cette première paroi 1 . Ce volet de recouvrement 3 est prévu pour venir recouvrir au moins la zone centrale 10 de cette première paroi 1 .  According to a preferred embodiment, the cover flap 3 is fixed by one of its longitudinal edges 30 to the first wall 1 and this between the central zone 10 of this first wall 1 and one of the longitudinal edges of this first wall 1.

Ainsi ces plantes peuvent croître sans que leur étage foliaire ou leur étage fructifère n'entre en contact avec le substrat de culture.  The covering and protection flap 3 is provided with through-holes 32 for the passage of the plants. Thus these plants can grow without their leaf stage or fruiting stage coming into contact with the culture substrate.
En figure 3 est représentée une installation de culture mettant en œuvre une bâche composite selon l'invention. On peut voir que cette installation de culture est formée de plusieurs buttes de terre 100, longitudinales, parallèles, séparées les unes des autres par des couloirs de circulation. Ces buttes de terre 100 forment des supports longiformes de section droite tronconiques et présentent chacune, en partie supérieure, une face plane horizontale formant table. Chaque butte 100 présente en outre deux flancs latéraux inclinés. Chaque butte de terre 100 est dotée d'un canal longitudinal 1 10 creusé depuis la face supérieure plane et d'une goulotte longitudinale 120 creusée depuis le fond du canal 1 10. La zone centrale 10 de la première paroi 1 est disposée dans le canal 1 10 et tapisse les parois de ce dernier pour former une goulotte apte à recevoir un substrat de culture. La seconde paroi 2, en forme de gouttière, est quant à elle disposée dans la goulotte 120. On peut voir en figure 3 que les deux zones de la paroi 1 latérales à la zone centrale, s'étendent sur les flancs latéraux de la butte de terre, les moyens de lestage assurant la mise en tension de cette première paroi 1 . On peut voir également sur cette figure que le volet de recouvrement 3 vient recouvrir la goulotte que forme la zone centrale 10 de la première paroi et que les perforations traversantes 32 qu'il présente se situent au droit de cette forme de goulotte. FIG. 3 shows a culture installation implementing a composite covering according to the invention. 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. The central zone 10 of the first wall 1 is disposed in the channel 1 10 and lines the walls of the latter to form a chute adapted to receive a culture substrate. The second wall 2, in the form of a gutter, is in turn disposed in the chute 120. It can be seen in FIG. 3 that the two zones of the wall 1 lateral to the central zone extend on the lateral flanks of the mound. earth, the weighting means ensuring the tensioning of this first wall 1. It can also be seen in this figure that the covering flap 3 covers the chute that forms the central zone 10 of the first wall and that the through perforations 32 that it has are located at the right of this form of chute.
Dans cette forme de réalisation, la paroi 2 formant gouttière pourra ne pas être fixée à la première paroi 1 . Dans ce cas, par ses deux zones marginales latérales elle pourra reposer sur le fond du canal 1 10 et par sa zone centrale épouser la forme de goulotte 120 formée dans la butte de terre. La seconde paroi 2 sera alors maintenue en place notamment par le poids du substrat de culture dans la goulotte que forme la zone centrale 10 de la première paroi 1 .  In this embodiment, the wall 2 forming gutter may not be attached to the first wall 1. In this case, by its two lateral marginal areas it can rest on the bottom of the channel 1 10 and its central area marry the chute shape 120 formed in the mound. The second wall 2 will then be held in place in particular by the weight of the culture substrate in the trough formed by the central zone 10 of the first wall 1.
En figure 4 est représentée une autre installation de culture des plantes. In Figure 4 is shown another plant plant culture.
Cette installation met en œuvre une bâche composite selon l'invention. Les bordures longitudinales de cette première paroi sont équipées d'ourlets de suspension dans lesquels sont engagées par exemple des tiges supports prévues pour coopérer en suspension avec des élingues de suspension connues en soi. This installation implements a composite covering according to the invention. The longitudinal edges of this first wall are equipped with suspension hems in which are engaged for example support rods provided to cooperate in suspension with suspension slings known per se.
Avec une telle variante d'exécution, au volet 3 pourra être associé un second volet 5 agencé en dôme au-dessus des plantes, ce second volet 5 pourra adopter la forme d'un dôme étant supporté par des structures en arceau ou autre structure appropriée. With such an alternative embodiment, the flap 3 may be associated with a second flap 5 arranged in a dome above the plants, this second flap 5 may take the form of a dome being supported by arch structures or other appropriate structure.
Dans ce cas de figure encore, la seconde paroi 2 constitutive de la gouttière d'évacuation pourra ne pas être fixée à la première paroi mais à la structure porteuse par ses bordures longitudinales.  In this case again, the second wall 2 constituting the drain gutter may not be attached to the first wall but the carrier structure by its longitudinal edges.
II va de soi que la présente invention peut recevoir tous aménagements et variantes du domaine des équivalents techniques sans pour autant sortir du cadre du présent brevet tel que défini par les revendications ci-après.  It goes without saying that the present invention may receive any arrangements and variations in the field of technical equivalents without departing from the scope of this patent as defined by the claims below.
