Description

Plant cultivation

The present invention has a light-sealed opaque structure in which external light is not transmitted and the inside of the plant is not visible from the outside, and the inner surface is made of a mirror surface, so that plant growth can be mass-produced at a low cost and with little labor. It relates to a plant factory (tray, plant growth bed) and configured as a unit.

The plant factory artificially controls the elements necessary for plant growth, such as light, water, oxygen, nutrient solution, carbon dioxide, humidity, temperature, and wind, so that plant growth is continuously and reliably without being influenced by environment, time and place. It is a facility that can control. In recent times, with abnormal growth, instability, and price fluctuations of plants caused by global warming and extreme weather, more and more plant factories grow efficiently in large spaces even in small spaces using artificial light. have.

Conventional plant plants have installed air conditioning facilities that can control temperature and humidity in open or enclosed spaces where 0-100% of the sunlight is blocked, and the shelf is placed inside to grow the plants grown thereon. It is in the form of a plurality, and the artificial light source is installed above the cultivation plant, and the nutrient solution supply facility is installed below. However, there is a problem that the installation cost is high due to the installation of a light source at each upper part of the cultivated crops, and a large amount of electric charges are generated. to be.

In relation to a plant factory, Korean Patent Laid-Open Publication No. 10-2010-0072436 discloses a plant factory lighting system having a plant factory light source for irradiating light quality with plants disposed in a standardized space using a central reflection mirror, Korean Patent Laid-Open Publication No. 10-2013-0063632 discloses a hydroponic cultivator having a light reflector attached to a planting plate to reflect artificial light or solar light upwards, but there is a limit to irradiating plants with uniform light quality.

In addition, conventionally, 1) for the purpose of directly observing and managing the growth state of the plant, 2) for direct use of natural light from the outside for photosynthesis, 3) light, nutrient solution, oxygen, carbon dioxide, humidity, temperature, For the convenience of controlling, maintaining, repairing and managing the facilities for the environmental conditions necessary for the growth of plants such as wind, etc. 4) For the purpose of receiving psychological stability and healing by observing the growth of plants, 5) Plant plants In the construction, for a variety of reasons, such as the purpose of simplifying the structure to reduce the cost, the use of open or transmissive redistribution in which light is transmitted from the outside to the inside. Therefore, it can be said that a typical plant factory is generally designed in such a way that a human can directly access the plant.

During the long history of agriculture, humans have managed to contact plants directly and without exception, so in the past, agriculture without humans was unimaginable, and there was no form of plant cultivation or plant factory in which no internal plants were identified from the outside. .

There are about 10,000 microorganisms in the human body (Reynolds T et al., NIH Human Microbiome Project defines normal bacterial makeup of the body.National Institutes of Health (NIH), News & Events, News Releases, 2012), 70 kg The total number of bacteria present in a standard male is estimated to be 3.8 × 10 ¹³ , and in particular, it is estimated that about 10 to ¹² bacteria are present in the skin (Sender R et al., Revised Estimates for the Number of Human and Bacteria). Cells in the Body.PLOS Biology, 2016, 14 (8): e1002533). Therefore, when these microorganisms are transferred to plants, they have no direct or indirect effects on the growth of plants, but also affect the CFU (Colony-forming unit) value, which is an indicator of cleanliness of the plants being grown. As such, the human body should also be considered as one of the hazards for the purpose of growing clean plants.

Therefore, the inventors of the present invention, by forming the cultivation in a light-sealing opaque structure in which all surfaces inside the plant cultivation is blocked and no light is transmitted outside, so that the plant inside the cultivation is not visible from the outside, thereby providing artificial It is possible to prevent the light emitted from the light source to be leaked to the outside and to prevent the introduction of microorganisms and contaminants such as viruses and bacteria from humans, where the top, bottom, left, right, front and back surfaces of the inside of the plant By constructing all of the mirror surfaces, the light emitted from the artificial light source is repeatedly reflected by the mirror surfaces inside the cultivation plant to irradiate the plants, and the utilization efficiency of the artificial light source is increased to reduce the electric energy cost, and the interior of the cultivation plant. It maintains constant illumination regardless of the location to promote plant growth, and artificial light source inside the cultivation The present invention was completed by devising a plant cultivation plant that gives design diversity by allowing the position of the plant to be freely positioned and a plant factory having the unit as a unit.

In the conventional plant factory, all or part of the front, rear, left and right sides of the cultivation are open or transmissive structures for the purpose of observation and management of plants or incidence of natural light from the outside. Much of the oil is leaked out and lost. In addition, PFAL (Plant Factory with Artificial Lightning), a plant factory that provides 100% artificial light source for photosynthesis, is able to grow all season clean plants without being affected by natural conditions such as seasons and weather conditions. On the other hand, it is accompanied by the cost of electric energy compared to the solar light that can be obtained free of nature, thereby increasing the production cost of the plant. In order to reduce these costs and increase profitability, consideration of the type, size, arrangement, wavelength, and irradiation method of artificial light sources is also important, but it is necessary to efficiently manage and use the emitted light.

In addition, since the leaves or stems that grow as the plants grow gradually cover the light emitted from the artificial light source and form a shade, the growth of plants in the shaded areas where the light does not reach in the plant cultivation is restricted, thus lowering the plant plant production rate. You lose. For example, when artificial light sources are installed on the top of the plant, the photosynthesis is achieved in the leaves of the upper part of the plant, but the shaded area under the upper leaves is insufficient in light, which limits the photosynthesis and thus lengthens the growth period of the plant. The problem of reducing profitability arises. That is, the roughness of the inside of the cultivation will vary depending on the position, which causes a restriction on the position of the artificial light source, this problem will increase as the plant grows.

In addition, contaminants such as microorganisms, bacteria, viruses and the like from outside including humans may penetrate and affect the growth of plants, and as a result, may affect the quality of the harvested plants. In other words, humans can be a risk factor in plant growth.

In order to reduce this problem, the present invention is a light-sealing opaque structure of the plant cultivation, and in particular, the upper, lower, left, right, front and rear of the inside of the plant cultivation by the mirror surface, from the artificial light source The light is irradiated to the plant by reflecting infinitely by the mirror surfaces inside the plant without irradiating to the plant outside, thereby increasing the utilization efficiency of artificial light and reducing the electric energy cost, and almost shade is formed in the plant. Therefore, it is possible to promote the plant growth by maintaining the constant illumination irrespective of the internal location of the cultivation, and to give the plant variety or the unit to give the design diversity to freely arrange the location of the artificial light source in the cultivation of the plant. It is an object to provide a plant factory provided by.

Another object of the present invention is to provide a plant plant or a plant factory provided as a unit for plant cultivation, which allows the mass production of high quality plants at low cost in a closed state with minimal direct contact with humans for cultivating clean plants. It is.

In order to achieve the object as described above, the present invention is the top, bottom, left, right, front and rear of the plant cultivation is blocked all the outside light is not transmitted and the plant inside the cultivation visible from the outside It is made of an optically sealed type opaque structure, and the upper, lower, left, right, front and rear surfaces of the cultivation interior are all opaque reflecting surfaces, especially mirror surfaces, so that light from the artificial light source inside the cultivation It provides a plant cultivation that is irretrievably reflected by the mirror surfaces inside the cultivation without being leaked to the cultivation outside and constantly irradiated to the plants inside the cultivation.

In the plant cultivation of the present invention, light emitted from the artificial light source does not leak out to the outside of the cultivation field and is repeatedly reflected by the mirror surfaces inside the cultivation field, thereby irradiating the plant, thereby increasing the utilization efficiency of the artificial light source and reducing the electric energy cost. It prevents the formation of shade in the cultivation plant to maintain the constant illumination irrespective of the position of the cultivation plant to promote the plant growth, and reduce the design diversity to freely arrange the position of the artificial light source in the plant cultivation plant. Can be.

Specifically, the light-sealing opaque plant cultivation of the present invention can effectively prevent the penetration of microorganisms, viruses, bacteria from the outside, including humans, so that the plants inside are not affected directly from the outside, including the human body stably grow and clean Plants can be obtained. In addition, the present invention can increase the utilization efficiency of the artificial light source inside the light-sealed opaque plant cultivation to reduce the amount of electrical energy used to lower the plant production cost. In addition, the present invention is to prevent the light from the artificial light source is blocked by the plant stem or leaves inside the light-sealed opaque plant cultivation plant to maintain a constant illumination in the cultivation plant to promote plant growth to reduce the growth period of the plant Lower production costs In addition, the present invention can provide a variety of design by allowing the location of the artificial light source inside the light-sealing opaque plant cultivation to be freely positioned without being limited to the top of the cultivation.
