Description

Dispositif pour le bouturage à chaud, la germination, le semis, la culture in vitro ou la culture contrôlée et/ou accélérée de végétaux.Device for hot cutting, germination, sowing, in vitro culture or controlled and / or accelerated culture of plants.
La présente invention concerne un dispositif pour le bouturage à chaud, la germination, le semis, la culture in vitro ou la culture contrôlée et/ou accélérée de végétaux.The present invention relates to a device for hot cutting, germination, sowing, in vitro culture or controlled and / or accelerated culture of plants.
De nombreux dispositifs ont été développés à ce jour pour permettre d'optimiser les paramètres de croissance des végétaux. Ces paramètres sont essentiellement au nombre de trois, à savoir : la lumière, l'humidité relative et la température. Parmi ces paramètres, le plus difficile à contrôler est le paramètre de la température. En effet, tous les dispositifs du type boîte à culture connus à ce jour soumettent les cultures à des variations de température importantes du fait de 1'existence de points froids et de points chauds à la surface de la face formant fond de l'enceinte. Or, comme le milieu de culture est généralement disposé directement sur cette face formant fond, il subit directement ces variations de température gui sont nuisibles à la croissance des cultures. Un dispositif présentant de tels inconvénients est par exemple décrit dans la demande de brevet EP-A-0.241.627. Ce document décrit une boîte de culture dans laguelle les moyens de chauffage permettant le chauffage de l'enceinte sont constitués par des résistances incorporées dans la face formant fond de ladite enceinte. De ce fait, sur la face du dessus de la face formant fond de cette enceinte, il existe des points chauds et des points froids, les points chauds correspondant à l'emplacement des résistances électrigues. Le milieu de culture est guant à lui répandu sur cette face du dessus et présente donc une température hétérogène. Il en est de même de la demande de brevet EP-A- 0.047.426 gui décrit une boîte de culture dans laguelle les moyens de chauffage sont noyés dans la masse de la surface formant fond et sont en particulier constitués par des éléments de chauffage pris en masse entre deux couches d'isolant collées l'une à l'autre. Enfin, ie brevet US-A- 2.963.819 décrit une boîte de culture portable dans laguelle la surface formant fond est éguipée d'une résistance électrigue gui est recouverte directement par le substrat de culture. C'est probablement la solution la plus mauvaise en terme de variations de température car le substrat de culture sera amené à présenter en certains points des températures très élevées et au contraire des températures très basses en d'autres points.Many devices have been developed to date for optimizing plant growth parameters. These parameters are essentially three in number, namely: light, relative humidity and temperature. Among these parameters, the most difficult to control is the temperature parameter. In fact, all the devices of the culture box type known to date subject the cultures to significant temperature variations due to the existence of cold spots and hot spots on the surface of the face forming the bottom of the enclosure. However, as the culture medium is generally placed directly on this bottom-forming face, it is directly subjected to these temperature variations which are detrimental to the growth of the cultures. A device exhibiting such drawbacks is for example described in patent application EP-A-0,241,627. This document describes a culture dish in laguelle the heating means for heating the enclosure consist of resistors incorporated in the bottom side of said enclosure. Therefore, on the top side of the bottom side of this enclosure, there are hot spots and cold spots, the hot spots corresponding to the location of the electrical resistors. The culture medium is spread widely over this face from above and therefore has a heterogeneous temperature. It is the same with patent application EP-A- 0.047.426 which describes a culture dish in the laguelle the heating means are embedded in the mass of the bottom surface and are in particular constituted by heating elements taken en masse between two layers of insulation stuck together. Finally, the US-A-2,963,819 patent describes a portable culture dish in which the bottom surface is provided with an electrical resistance which is covered directly by the culture substrate. This is probably the worst solution in terms of temperature variations because the culture substrate will have to present at certain points very high temperatures and on the contrary very low temperatures at other points.
Le but de la présente invention est de proposer un dispositif gui permette une culture contrôlée et/ou accélérée des végétaux grâce à une régularisation de la température et du taux d'humidité dans ladite enceinte à un coût moindre avec, en raison de sa conception, la possibilité de récupérer les eaux de condensation permettant un arrosage espacé des végétaux.The object of the present invention is to provide a device which allows a controlled and / or accelerated cultivation of plants by regulating the temperature and the humidity level in said enclosure at a lower cost with, due to its design, the possibility of recovering condensation water allowing sparse watering of plants.
L'invention concerne à cet effet un dispositif pour le bouturage à chaud, la germination, le semis, la culture in vitro ou la culture contrôlée et/ou accélérée de végétaux, du type comprenant une enceinte fermée ou partiellement fermée munie d•au moins une porte pour permettre 1'accès à l'intérieur de ladite enceinte, caractérisé en ce gue cette enceinte comporte un double fond ménageant une cavité fermée incorporant des moyens de chauffage gui chauffent l'air contenu dans ladite cavité gui, par contact, fait varier la température de la face du dessous de la face formant fond de ladite enceinte, cette face formant fond étant recouverte par un substrat, rétenteur d'eau, à capacité calorifigue élevée, tel gue du sable, de la perlite, de la vermiculite, de la terre végétale ou similaire, gui permet d'une part la maîtrise du taux d'humidité relative de ladite enceinte, d'autre part, une maîtrise des variations de température à 1•intérieur de l'enceinte.To this end, the invention relates to a device for hot cutting, germination, sowing, in vitro culture or controlled and / or accelerated culture of plants, of the type comprising a closed or partially closed enclosure provided with at least a door to allow access to the interior of said enclosure, characterized in that this enclosure has a double bottom providing a closed cavity incorporating heating means which heat the air contained in said mistletoe cavity, by contact, varies the temperature of the bottom face of the bottom face of said enclosure, this bottom face being covered by a substrate, retaining water, with a high heat capacity, such as sand, perlite, vermiculite, topsoil or the like, which allows on the one hand control of the relative humidity level of said enclosure, on the other hand, control of temperature variations 1 • inside the enclosure.
Selon une forme de réalisation préférée de l'invention, les moyens de chauffage de 1•enceinte sont constitués par une résistance électrigue d'une certaine puissance dont le temps de chauffe est régulé au moyen d'un thermostat associé à au moins une sonde de température.According to a preferred embodiment of the invention, the heating means of the enclosure consist of an electrical resistance of a certain power, the heating time of which is regulated by means of a thermostat associated with at least one temperature probe. temperature.
• L'enceinte peut également être constituée d'un fond comportant le dispositif de l'invention surmontée d'une cloche.• The enclosure can also consist of a bottom comprising the device of the invention surmounted by a bell.
L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence au dessin annexé gui représente une vue en coupe transversale de l'exemple de réalisation d'un dispositif conforme à l'invention.The invention will be clearly understood on reading the following description of exemplary embodiments, with reference to the accompanying drawing which shows a cross-sectional view of the exemplary embodiment of a device according to the invention.
Conformément à la figure unigue, le dispositif, objet de l'invention, se présente sous forme d'une enceinte 1 généralement parallélépipédigue. Cette enceinte est fermée ou partiellement fermée. Elle comporte un élément ouvrant-fermant tel gu'une porte 5 d'accès à l'intérieur de ladite enceinte. La face formant fond 7 de cette enceinte comporte un double fond formant une cavité 10 fermée à l'intérieur de laguelle sont disposés des moyens de chauffage 2. Ces moyens de chauffage sont généralement constitués par une résistance ou des résistances électrigues 2 ou par des moyens similaires à ceux mis en oeuvre lors de la réalisation d'un chauffage au sol. Ces résistances électrigues 2 sont placées en suspension à l'intérieur de la cavité 10 ménagée dans le double fond de l'enceinte 1 comme le montre la figure unigue. Le maintien en suspension des moyens de chauffage 2, généralement sensiblement centralement à l'intérieur de la cavité 10, est réalisé au moyen d'organes de fixation appropriés tels gue des câbles. Une plague conductrice 12 est fixée sur les résistances électrigues 2. Cette plague 12, également suspendue en position centrée à l'intérieur de la cavité 10, joue le rôle d'accumulateur et de dissipateur de chaleur en cas de défaillance des moyens de commande et de contrôle des moyens de chauffage 2. Ces moyens de chauffage 2 sont d'ailleurs généralement contrôlés et commandés au moyen d'un thermostat 3 associé à au moins une sonde de température (non représentée) disposée entre les résistances 2 et fixée à la plague 12. La mise en fonctionnement des moyens de chauffage 2 après mesure de la température de 1'enceinte 1 au moyen d•une sonde de température entraîne, une production de chaleur gui chauffe l'air contenu dans la cavité 10 délimitée par le double fond de 1'enceinte 1. Cet air engendre par son contact avec la face du dessous de la face formant fond 7 de 1'enceinte 1 une variation de température de cette dernière. Ce chauffage indirect permet d'obtenir des variations de température très faible de la face formant fond 7 de l'enceinte 1.According to the single figure, the device, object of the invention, is in the form of an enclosure 1 generally parallelepiped. This enclosure is closed or partially closed. It comprises an opening-closing element such as a door 5 for access to the interior of said enclosure. The bottom face 7 of this enclosure has a double bottom forming a cavity 10 closed inside the laguelle are arranged heating means 2. These heating means generally consist of an electrical resistance or resistances 2 or by means similar to those used when producing underfloor heating. These electrical resistors 2 are placed in suspension inside the cavity 10 formed in the double bottom of the enclosure 1 as shown in the single figure. Maintaining the heating means 2 in suspension, generally substantially centrally inside the cavity 10, is carried out by means of suitable fixing members such as cables. A conductive plague 12 is fixed on the electrical resistors 2. This plague 12, also suspended in a centered position inside the cavity 10, plays the role of accumulator and heat dissipator in the event of failure of the control means and for controlling the heating means 2. These heating means 2 are moreover generally controlled and controlled by means of a thermostat 3 associated with at least one temperature probe (not shown) disposed between the resistors 2 and fixed to the plague 12. Putting the heating means 2 into operation after measuring the temperature of the enclosure 1 by means of a temperature probe results in a production of heat which heats the air contained in the cavity 10 delimited by the double bottom of the enclosure 1. This air generates, by its contact with the bottom face of the bottom forming face 7 of the enclosure 1, a temperature variation of the latter. This indirect heating makes it possible to obtain very low temperature variations of the bottom forming face 7 of the enclosure 1.
Cette variation de température est en outre limitée et régulée par le substrat 8 disposé sur la face du dessus de la face formant fond 7 de l'enceinte 1. Il est à noter gue généralement cette face du dessus de la face formant fond 7 affecte la forme d'une cuvette comme le montre la figure unigue. Le fond 7 de l'enceinte 1 ainsi chauffé est donc recouvert sur sa face du dessus d'un substrat 8 à capacité calorifigue élevée. Ce substrat 8, jouant le rôle d'un régulateur thermigue, peut être de nature diverse. A titre d'exemple, on pourra citer du sable, de la perlite, de la vermiculite, de la terre végétale ou similaire. Ce substrat 8 rétenteur d'eau est, lorsgu'il est placé dans l'enceinte 1, plus ou moins saturé en eau. Les végétaux 4 et le milieu de culture 11 sont eux-mêmes disposés sur ce substrat 8 et peuvent pénétrer plus ou moins dans ledit substrat 8. • L'enceinte 1 peut également comporter des moyens d'éclairage en soi connus.This temperature variation is further limited and regulated by the substrate 8 disposed on the top face of the bottom face 7 of the enclosure 1. It should be noted that generally this face of the top of the bottom face 7 affects the shape of a bowl as shown in the single figure. The bottom 7 of the enclosure 1 thus heated is therefore covered on its top face with a substrate 8 with high heat capacity. This substrate 8, playing the role of a thermal regulator, can be of a diverse nature. By way of example, mention may be made of sand, perlite, vermiculite, topsoil or the like. This water-retaining substrate 8 is, when placed in the enclosure 1, more or less saturated with water. Plants 4 and the middle of culture 11 are themselves disposed on this substrate 8 and can penetrate more or less into said substrate 8. • The enclosure 1 may also include lighting means known per se.
Grâce à cette disposition du substrat 8 par rapport aux moyens de chauffage 2 de 1'enceinte 1 et sous réserve que la puissance de l'élément chauffant soit suffisamment importante, le fond 7 de l'enceinte 1 va être porté à une température correspondant à une température où 1'eau située au fond de 1'enceinte 1 va se transformer en vapeur 9, cette vapeur 9 va diffuser dans le volume de l'enceinte 1 jusgu'à un certain taux d'humidité relative déterminé par les principes physigues des changements d'état de la matière. De ce fait, on obtient un éguilibre permanent entre le taux d'humidité et la température à l'intérieur de l'enceinte 1. En outre, en raison de la disposition du substrat 8 et de sa capacité calorifiqueThanks to this arrangement of the substrate 8 relative to the heating means 2 of the enclosure 1 and provided that the power of the heating element is sufficiently high, the bottom 7 of the enclosure 1 will be brought to a temperature corresponding to a temperature where the water located at the bottom of the enclosure 1 will transform into vapor 9, this vapor 9 will diffuse in the volume of the enclosure 1 until a certain relative humidity level determined by the physical principles of changes in state of matter. As a result, a permanent equilibrium is obtained between the humidity rate and the temperature inside the enclosure 1. In addition, due to the arrangement of the substrate 8 and its heat capacity
.élevée, ce dernier va éliminer partiellement toutes les variations de température évitant ainsi des évolutions de la température qui pourraient être néfastes à la culture. Cette régulation des variations de température est liée aux capacités d'absorption et de restitution d'énergie du substrat. Ce substrat 8 joue donc un double rôle..high, the latter will partially eliminate all temperature variations, thus avoiding changes in temperature which could be harmful to the crop. This regulation of temperature variations is linked to the energy absorption and restitution capacities of the substrate. This substrate 8 therefore plays a double role.
En outre, si l'on prend la précaution d'éguiper au moins la porte 5 d*un système de guidage 6 de 1'eau de condensation vers la face formant fond 7 de l'enceinte 1, on peut obtenir un dispositif gui nécessitera très peu d'entretien en particulier au niveau des cycles d'arrosage. En effet, l'eau se condensant contre les parois de 1'enceinte est récupérée grâce à ce dispositif de guidage et est ramenée directement au substrat 8 rétenteur d'eau gui réabsorbe cette eau. Ce système de guidage 6 peut être constitué par un rebord ou par un joint double comme le montre la figure unigue.In addition, if we take the precaution of cleaning at least the door 5 of a guiding system 6 of the condensing water towards the bottom face 7 of the enclosure 1, it is possible to obtain a device which will require very little maintenance, particularly in terms of watering cycles. In fact, the water condensing against the walls of the enclosure is recovered using this guide device and is brought directly to the water-retaining substrate 8 which re-absorbs this water. This guide system 6 can be constituted by a flange or by a double seal as shown in the single figure.
On obtient ainsi à faible coût une enceinte de culture dont les variations de température à 1'intérieur de 1'enceinte sont comprises dans une plage de guelgues dixièmes de degré Celsius avec un taux d'humidité guasiment constant tout en utilisant des moyens de chauffage classigues et donc peu onéreux. A culture chamber is thus obtained at low cost, the temperature variations inside the chamber being within a range of tenths of a degree Celsius with a practically constant humidity level while using conventional and therefore inexpensive heating means.
