The technical FIELD TO WHICH the INVENTION RELATES.

The invention relates to agriculture, in particular to a device for growing plants in the greenhouse, and is intended for growing plants with reduced levels of the isotope carbon-14.

The LEVEL of TECHNOLOGY

Known greenhouse for growing plants with reduced levels of the isotope carbon 14 for U.S. patent No. 5956896, CL USA 47/58 .1, IPC And 01 G 007/02. Greenhouse (“apparatus for growing plants according to claim 9 claims) contains ventilated structure with an inner space, a device for removing carbon dioxide from the ambient air, the generator of carbon dioxide with a low concentration of the isotope carbon-14.

The system works as follows: to maintain a reduced content of the isotope carbon 14 in the atmosphere of the greenhouse interior space of the greenhouse is sealed from the ambient atmospheric air, the replenishment of the internal air is outside air, the last two stages of training: at the first stage removes atmospheric carbon dioxide using a device for absorbing carbon dioxide in the second stage of this air is added to carbon dioxide with low content of carbon isotope 14.

The disadvantages of the known greenhouse are the lack of temperature control within the indoor air, the absence of a preservation system tightness when skipping personnel and equipment inside the greenhouse, the absence of a system for removal of carbon dioxide emitted by the soil.

The INVENTION

The object of the present invention is the provision of growing plants in a strictly controlled environment, air environment, in particular in the environment with reduced content of the isotope carbon-14.

Conventional greenhouses are used for growing certain types of plants that are outdoors this area or in a certain season of the year to grow impossible.

The proposed greenhouse used for growing plants not on the climatic conditions of the area, therefore, for economic reasons should be placed in those climatic conditions, where on the one hand sufficient light conditions, and on the other hand cheaper it will be possible to maintain the desired temperature growth of plants, preferably regardless of the time of year. The lighting conditions are improved with the placement of greenhouses in the lower latitudes, but at the same time complicated the task of maintaining the required temperature, typically arises the need for cooling air. Intuitively seem to be the most advantageous mountains of the tropics or coastal areas with short shelf, with the possibility of p is ostogo access to the deep cold waters (e.g. upwelling areas) or the presence of cold river flows, usually near mountain ranges. Given the defined conditions of application of the greenhouse and strict requirements on the tightness, the main task is to maintain the air temperature inside the greenhouse within the best growing plants. The solution of the stated problem is achieved by using the air conditioner. The type of conditioning depends on climatic conditions, using a greenhouse. The most common air conditioner compression type is the most versatile and suitable for any type of climate, in addition, may work means that is not only cool, but warm air, if it's necessary, but it requires a lot of energy costs. At low ambient air humidity (50%) and a small temperature differences (up to 20 degrees Celsius) may apply conditioner evaporative type. In the case of low temperature atmospheric air below the temperature required for growing these plants) you can use it for cooling the internal air of the greenhouse air heat exchanger type. If near the location of the greenhouse there is a source of water having a temperature below the temperature required for growing these plants, that can be applied to the heat exchanger air-to-water type, on the air side is Teploobmennik passed the internal air of the greenhouse, and on the water side of the water passes. In the case of water shortage can be applied to the closed loop circulation, which is in series with the heat exchanger included the tower.

Additional means of temperature stabilization is the use of material, delays of electromagnetic radiation in the infrared region of the spectrum, as transparent to visible light covering of the greenhouse.

The task of sealing the gap of personnel and equipment is solved by use of the vestibule, the effectiveness of the platform increases when using the door locking system, which can be opened only internal or only external doors.

Violation sealing greenhouse inevitably leads to the ingress of atmospheric air into the internal atmosphere of the greenhouse and by introducing carbon dioxide containing the isotope carbon 14, may affect the quality of the plants. The most likely case of violation of encapsulation can be considered destruction transparent to visible light coating performed as a rule of the silicate glass. The present invention proposes to use a translucent cover made of impact resistant material, such as laminated glass, or polymeric materials with high toughness, such as polycarbonates.

Gradual pollution of setopress knogo coverage requires periodic cleaning procedures. Coating the surface of a transparent coating of an oxide film, such as tin oxide, reduces contamination of the surface by reducing grazhdanina and as a consequence reduces the need for cleaning the surface of the translucent cover.

The soil in the greenhouse is a substance which in its composition usually contains organic matter, decomposition products of which are gases (mainly carbon dioxide and methane), which in turn contain the isotope carbon-14. To prevent the ingress of gaseous decomposition products of the soil in the internal atmosphere of the greenhouse system used air drainage, which is made in the form of soil above-ground mulch layer of not emitting carbon-containing gas of a material with a specific gravity significantly lower specific weight of the soil, for example clay chips, and a porous subsoil layer of inert material, such as gravel, among which laid the drainage pipe with the entire length of the holes at the ends of the drainage pipes come out of the greenhouse. The increased pressure of the air inside the greenhouse provides permanent removal of these gases. The low proportion of above-ground mulch layer allows him to always remain on the surface of the soil with the irrigation water or soil, such as loosening, prepyatstvovat penetration released from the soil gases into the internal atmosphere of the greenhouse.

To accelerate the ripening of crops in the internal atmosphere of the greenhouse is introduced ethylene. Introduction ethylene is produced only in the period of ripening of the crops and in quantities close to the amount of added carbon dioxide.

INDUSTRIAL APPLICABILITY

The present invention can be used in various modifications of the design, the specification of which depends primarily on the plants that need to grow, and the issue in which geographical area the greenhouse will be placed.

For example, for growing lettuce, you must maintain a temperature no higher than 18 degrees Celsius, the lighting can be weak (from 300 to 1000 suites) and clock. For cultivation of tomatoes temperature should not be below 16 degrees Celsius and the lighting should be strong, desirable direct sunlight, but during the short daylight saving time. Therefore, for growing lettuce greenhouse can be located at high latitudes and in summer the plants (or greenhouse) you want to shadow, and to grow tomatoes easier, having a greenhouse, for example, in the mountains of the tropics (where by the way the tomatoes and place).

Example: the Greenhouse is designed for growing herbs and vegetables. Located in the Moscow region. The greenhouse contains a sealed internally the space, having transparent to light the floor, the device for removing carbon dioxide from entering from the outside ambient air, the device for the production of carbon dioxide gas with a low content of the isotope carbon 14, a system for regulating the temperature of the air inside the greenhouse, the lobby for the passage of personnel and equipment inside the greenhouse, the air drainage system to add to the internal air of the greenhouse ethylene with a lower content of the isotope carbon-14. System for temperature control consists of a radiator located inside the greenhouse, while the radiator is blown by the fan, and as a coolant in the warmer months used water from underground wells, whose temperature is about 4 degrees Celsius in the cold season at this same radiator hot water for heating. Lobby for the passage of personnel and equipment inside the greenhouse is made in the form of additional flow areas with sealed entrance doors and sealed the door to enter into the greenhouse, while the doors have a mutex, that is, both doors cannot be opened together, which eliminates the violation of the seal of the greenhouse.

Air drainage is performed as follows: when laying ridges or shelves inside th is s in the beginning on future ridges or shelves, padded PVC pipes (for example, of polyethylene or PVC) with a diameter of 100 mm, which is done by small holes along the entire length (hole diameter 5 to 10 mm). Pipes have a small incline in the same direction from which they emerge from the greenhouse. The top of the pipe backfilled with gravel. Then is poured soil for growing vegetables usually the thickness of the soil layer at least 30 cm). After planting seedlings on the ground, poured a thickness of 1 to 2 inches of mulch layer of expanded clay aggregate. When growing plants is used the conventional technology of growing plants with the following differences. The greenhouse is always sealed, the temperature mode is supported only by changing the intensity of cooling or heating. When growing tomatoes during ripening to accelerate their redness in the atmosphere of the greenhouse can be added ethylene gas with a reduced content of the isotope carbon-14. The concentration of ethylene in the atmosphere of the greenhouse can be brought up to 0.03%. Commercially available ethylene is produced either from natural gas or petroleum-based products, which contain practically no isotope carbon-14.
