    [0001] 1 Aboveground cultivation module in which plant roots are fed by a nutritive fog, set of modules and associated method.
    [0002] The invention mainly relates to an improved soil culture module including providing means for forming a nutrient mist. The invention also relates to a set of modules and a method of feeding nutrient mist associated.
    [0003] Above ground plant crops are grown on a substrate in which the plant roots are found and which is fed continuously or periodically with a nutrient solution. Hydroponics is known to irrigate the neutral, inert substrate of a nutrient solution that contains mineral salts, nutrients, and any other plant growth promoting element. This type of soil-less culture is gradually replaced by the aeroponic culture, which uses techniques for vaporizing nutrient solutions of the substrate in a closed circuit. This technique has the advantage of feeding the substrate both with nutrients and with air, and of being able to limit the use of water while controlling the parameters of the nutrient medium, in particular by limiting the introduction of elements. harmful in the nutrient solution. A new technique declined from the aeroponic culture appeared recently. This is the ultraponic culture in which the spraying of nutrient solution is carried out by means of an ultrasonic mist forming droplets of very fine nutritive solutions of less than 5 microns. The plants are placed in supports positioned on a support element which delimits a root chamber in which is produced the nutrient solution mist of the aerial part of the plants. While this technique promotes the rapid growth of most plants and fungi compared to aeroponics, its performance is still limited for some plants. The invention is in the context of the above-ground culture by vaporization and more particularly of the ultraponics-type soil culture.
    [0004] The present invention relates to an above-ground cultivation module in which the roots of the plants are fed by a fog of nutrient solution and whose efficiency on the growth of plants is greater than the existing soil-less crop modules.
    [0005] To this end, the above-ground cultivation module of the invention comprises a plant support element delimiting a root chamber of the aerial part of the plants, which is essentially characterized in that it comprises means for forming plants. a mist of nutrient solution and means of circulation of said nutrient solution mist located in the root chamber.
    [0006] The above-ground cultivation module of the invention may also include the following optional characteristics considered in isolation or in any possible technical combination: the means for forming the nutrient solution mist comprise an ultrasonic atomizer located in the bottom of an misting cell which is fed with liquid nutrient solution and on which is provided at least one nutrient fog propagation opening in the root chamber, and the nutrient solution mist circulating means are located near said opening. the misting cell is cylindrical, extends from the bottom of the root chamber to an open upper neck forming the propagation opening of the nutrient mist facing and near which are arranged the means of circulation of the nutrient solution mist, and comprises air circulation lumens provided on its side walls ensuring the circulation of air in said misting cell. The propeller of a fan forming means of circulation of the nutrient solution mist is arranged facing and close to the open upper neck of the cylindrical misting cell, said propeller being offset from its actuating motor located on the side of the aerial part of the plants. the aerial part of the plants is confined in a removable waterproof bell. the misting cell is fed with nutrient solution from a liquid nutrient solution reserve connected to said misting cell by at least one nutrient solution circulation conduit into which the nutrient solution is sent by means of a pump disposed in the said reserve, and a 3031003 3 evacuation duct extends from the side wall of the misting cell to a discharge tray of the overflow ensuring the evacuation of the overflow of nutrient solution of the said misting cell. the nutrient solution reserve is arranged under and in the extension of the root chamber, also forming the discharge tray of the overflow of the misting cell and being separated from the root chamber by a wall having sealed openings respectively of passage of the flow conduit of the nutrient solution to the fogging cell and passage of the discharge conduit of the nutrient solution of the misting cell. the discharge tank of the overflow of the misting cell is connected to the nutrient solution reserve by means of a connecting pipe in which the overflow solution is circulated by means of a pump disposed in the said drain pan.
    [0007] The invention also relates to a set of above-ground cultivation modules which is essentially characterized in that it comprises at least two modules as previously described, comprising an evacuation tank of the overflow of the misting cell. connected to the supply of nutrient solution by a connecting conduit, and a common supply of nutrient solution which feeds the respective misting cells of the at least two modules. Finally, the invention relates to a method for propagating a nutrient solution mist in an above-ground root chamber of plants which is essentially characterized in that it provides for the use of at least one module or a set of modules as previously described, and in that regulates the duration and the rhythm of the active periods of formation of the nutrient solution mist in the root chamber. Other characteristics and advantages of the invention will emerge clearly from the description which is given below, by way of indication and in no way limitative, with reference to the appended figures among which: FIG. 1 is a diagrammatic representation in section of an aboveground cultivation module of the invention according to a first variant, and - Figure 2 is a schematic sectional representation of a set of above-ground cultivation modules according to a second variant.
    [0008] With reference to FIG. 1, the aboveground cultivation module of the invention 1 extends along a principal axis XX 'and comprises an aerial part 2 of the plants 3 and a root chamber 4 which are delimited in a leaktight manner. by a support 5 for holding the substrate pots 6 receiving the roots 7 of the plants 3 which extend downwards in the root chamber 4 through unrepresented orifices which are formed in the substrate pots 6. A cell misting 9 rests in a sealed manner on the bottom 8 of the root chamber 4, having a cylindrical configuration centered on the main axis XX 'of a diameter of 14 centimeters which extends towards the top of the root chamber 4 on a height adapted to the height of the root chamber 4. At the bottom of the misting cell 9 is disposed an ultrasonic misting machine 10 which has been previously coated with hydrophobic resin with the exception of the ceramic pellet qu It ensures the formation of the nutrient solution mist by its vibrations at a suitable frequency. The ceramic pellet is covered with liquid nutrient solution 11 whose level is controlled by a discharge duct 12 which extends from the side wall 13 of the misting cell 9 to 5 centimeters from the bottom 14 of the misting cell 9. to a reserve of nutrient solution 15 located under and in the extension of the root chamber 4 and which thus also forms the discharge tray of the overflow of the misting cell 9. For this purpose, a sealed orifice 16 of The evacuation duct 12 is provided in the bottom wall 8 of the root chamber 4. The evacuation duct 12 makes it possible to avoid the use of known bulky buoys to keep the ultrasonic mist away from the surface of the liquid. The misting cell 9 is fed with liquid nutrient solution from the nutrient solution reservoir 15 by means of a pump 17 and a nutrient solution circulation conduit 18 which extends to the open upper neck 20 of the Misting cell 9 forming nutrient fog propagation opening in the root chamber 4. For this purpose, a leaktight orifice 21 for passage of the discharge conduit is formed in the bottom wall 8 of the root chamber 4. At about 12 centimeters from the bottom 14 of the misting cell 9, a series of air circulation lights 22 are formed on the periphery of the lateral walls 13 of the misting cell 9 to ensure the circulation of air in said cell 9 As shown in FIG. 1, a removable plastic bell 23 covers the aerial part of the plants 2. It is possible to provide for the use of a heating cord to control the temperature at the the aerial part of the plants 2 thus forming a greenhouse for germination and cuttings and avoiding delicate transplantation operations. According to the invention, a fan 25 is arranged at the support 5 holding the substrate pots 6 coaxially with the upper open neck 20 of the misting cell 9. More specifically, the fan 26 of the propeller 26 is located near the upper open collar 20 of the misting cell 9 being off-axis, relative to the main axis XX ', of the drive motor 27 of the propeller 26 which is located on the support 5 for holding the substrate words 6 for the aerial part of the plants 2. For this purpose, a sealed orifice 28 is formed in the support 5 for holding the substrate pots 6 to connect the shaft 29 connecting the motor 27 to the fan propeller 26 25. The propeller 26 of the fan 25 located near the open neck 20 of the misting cell circulates the mist of nutrient solution 30 formed by the misting cell 9 throughout the root chamber 4 while conferring on the roots 7 an app Maximum oxygen output far superior to all existing above ground crop systems. The operation of the propeller 26 which mixes the nutrient solution mist 30 without the outside air entering the root chamber 4 causes the formation of a depression to confine the nutrient mist circulating in said root chamber 4 .
    [0009] In order to effectively circulate the nutrient solution mist 30, the nutrient solution mist circulation means formed in this embodiment by the off-axis propeller 26 of its drive motor 27 must be located within the root chamber and preferably near the propagation opening of the nutrient mist 30 formed in the misting cell 9 which is also located in the root chamber 4. With reference to FIG. 2, a set of modules according to the invention has two modules 1a, 1b identical to the module 1 of Figure 1 in that for each of them a misting cell 9a, 9b extends along the axis 3031003 6 principal respective XX'a, XX'b of the module concerned 1a, 1b being placed in the bottom 8a, 8b of the root chamber 4a, 4b. The fogging cell 9a, 9b comprises air circulation slots 22a, 22b and an upper open neck 20a, 20b forming a nutrient fog propagation opening in front of which 5 is coaxially disposed the propeller 26a, 26b of a fan 25a, 25b whose motor 25a, 25b is offset along the main axis XX'a, XX'b and located on the side of the aerial part of the plants 2a, 2b. In this variant embodiment and in contrast with the module 1 of FIG. 1, the nutrient solution reserve 151 is common to the two modules 2a, 2b and each misting cell 9a, 9b is connected to an evacuation tank 152, 153 of the overflow distinct from the common supply of nutrient solution 151. More specifically, a pump 171 situated in the common nutrient solution reserve 151 circulates the liquid nutrient solution 191 through a common circulation conduit 181 which divides in two 182,183 circulation ducts conveying the nutrient solution to the respective open upper necks 20a, 20b of the misting cells 9a, 9b of each of the modules 1a, ib. Each misting cell 9a, 9b comprises a discharge duct 12a, 12b of the overflow of nutrient solution 11a, 11b covering the associated ultrasonic fogger 10a, 10b which extends, as for the module 1 of FIG. from the side wall 13a, 13b of the misting cell concerned 9a, 9b to the associated overflow evacuation tank 152, 153 suitable for reinjecting the nutrient solution from the overflow into the common nutrient solution storage tank 151 using a pump 154,155 and a connecting conduit 156,157. Thus, the nutrient overflow of the misting cells 9a, 9b of each module 1a, 1b is reintroduced into the nutrient solution circulation loop. Alternatively, the module 1 of FIG. 1 may also comprise a reserve of remote nutrient solution such as that of FIG. 2 as well as an overflow evacuation tank independent of the nutrient solution reserve, for example for reasons congestion by limiting the height of the module 1. It may also be possible to predict the presence of several fogging cells in a single culture module. This is the case when the root chamber has a volume greater than a certain threshold, for example 90 liters.
    [0010] Alternatively, the set of modules of Figure 2 may comprise a set of three or four modules. Finally, the duration and the rhythm of the active periods of formation and circulation of the nutrient solution mist in the root chambers 4; 4a, 4b of the module or modules 1; 1a, 1b are controlled according to the specific needs of the plants contained in the modules 1; 1a, 1b. By way of example, it is possible to provide a formation and circulation cycle for the solution mist of 15 minutes every hour. Durations and rhythms can evolve during the evolution of plant growth. Control means not shown but known to those skilled in the art can actuate the activation and deactivation of the ultrasonic atomizer (s) of the misting cells. 15
