Description

  The present invention relates to the fields of agriculture, horticulture, agriculture and agricultural economics of food, energy and other organic materials. Specifically, it relates to optimization of plants, yield, photosynthetic energy conversion efficiency, and utilization efficiency of other resources including time, space, water and nutrients. More specifically, the present invention relates to indoor three-dimensional (3D) environmentally controlled farming, space, and vertical farming that are performed independently of solar energy or soil. The present invention also relates to a three-dimensional agricultural system composed of a plurality of layers that maintain plant growth. More specifically, the layers are permeable in the sense that each layer penetrates water, nutrients, light, buds and roots from adjacent layers.

  The entire copending patent application “SanSoil (Soil-less indoor farming for food and energy production)” is incorporated herein by reference. This application, which details the limitations and disadvantages of conventional soil-based agriculture, is hereinafter referred to as “the First SanSoil Application” or “FSA”. In this application, an advanced teaching on alternative non-soil three-dimensional multi-layer farming based on the law of ensuring agricultural profitability (AgriPAL), a novel plant growth model (PGM) was presented.

  In general, AgriPAL and PGM, for the first time, have published mathematical analysis foundations based on scientific principles, but have shown the function of photosynthesis and presented prediction formulas for yield, energy efficiency, and agricultural profitability. These have unraveled the mysteries that have not been captured by plant scientists and agronomists until now. And the concept of the extremely high physiological gain collected by the means for evaluating solar gain and resource utilization efficiency was clarified. These gains increase yields and efficiencies by a factor of over 10 and increase the approach path by a factor of 100.

  The FSA contributes to many of the progressive inventions presented in this application and subsequent related applications. Therefore, this application relies heavily on the background, formulas and teachings of FSA.

Is it possible to produce enough food to adequately supply the world's people?
Along with improving nutritional status, the development of health sciences and technology has provided a way to virtually eliminate infant mortality, while life expectancy is about to exceed 80 years. As a result, the world population is expected to be at least 9 billion by 2050. The projected population size has been recognized for many years as the greatest challenge facing our planet, but it has limited resources such as food, energy, land and water, and has It encourages tough competition and conflict to gain and maintain a high life and lifestyle.

This is a recent issue of the United Nations Food and Agriculture Organization (FAO), which announced the outcome of the High Level Expert Forum entitled “The 2050 World Food Issues” held in Rome on October 13-13, 2009. ). In addition, CO ₂ -Science issued by the Center for Global Change Research and Global Change Research (issued June 15, 2011), “Predicting global food production in 2050: Providing food to people around the world appropriately. In a paper entitled “Can enough food be produced?” D. Dr. Idso emphasized this issue (Non-Patent Document 1).

  Both FAO and Dr. Idso have agreed on the following worrisome points: It is a significant reduction in per capita world food production, arable land, water resources, and field yields of staple crops. In order to avoid catastrophic consequences, they both point to the need for a rapid paradigm shift in food production technologies, systems and methods. The current food supply-demand gap continues the devastating consequences of hunger, malnutrition and starvation in many parts of the world. According to FAO, 1 billion people will be hungry in 2012. In the 2050 population of 9 billion, this gap is expected to expand further. In addition to hunger in many parts of the world, geopolitical instability will have immeasurable effects on human welfare.

Furthermore, these issues appear in the following three contradictions.
Contradiction No. 1: Food vs. Carbon dioxide reduction Many people are concerned that carbon dioxide emissions are causing global warming. Such people are working to reduce the use of fossil fuels, claiming to reduce CO ₂ and demanding it from the government. People have the power to move the government, and laws around the world are in place to curb the use of resources that increase CO ₂ . However, this is in direct conflict with the first priority of maintaining life and supplying food to the world. Currently, 1 billion hunger is an urgent problem, and in 2050 it will swell to 3-4 billion. A group worried about “global warming” uses suspicious photosynthetic models to predict the disastrous consequences of humanity in 2100 while understanding why plant food efficiency is less than 0.5% (Table 1) It is a contradiction that the same model cannot be used to do this. If there is a complete and accurate understanding, and at the same time better absorb the heat as CO ₂ is large, food and bio-fuel will be seen that it is possible to cope with urgent need for status quo. In short, CO ₂ is a major component of food and life (hydrocarbons are important for living organisms).

Contradiction No. 2: Food vs. food. Direct result caused by the fuel de-global warming, transportation fuels CO ₂ emissions zero from biomass, to produce biofuel, USA, is a regulatory EU, and other countries have imposed. As a result, when the highest priority is to feed the world's population, a second contradiction occurs. Many people are worried that scarce resources that have been devoted to food production, such as arable land, water, seeds, fertilizers, herbicides, and biofuels that divert farm equipment in other directions will exacerbate the problem. To do. The resulting pressure on food and energy prices will make it more difficult to solve the nutritional disparity problem of many disadvantaged people on the planet. There is concern that the number of such people will increase. There is also a contradiction in securing food and energy.

Contradiction No. 3: Food vs. Forests As shown in Table 1, plant scientists and agronomists agree that the efficiency measure is less than 0.5%, but the loss source of less than 99.5% is sufficient. I can't explain it. Fully explaining this loss is the key to an innovative way to minimize it.

  Plants store solar energy in the form of molecular binding energy of carbohydrates, sugars, starches, celluloses, proteins. In order to economically produce commonly available staple crops (sugars, grains, beans, leafy vegetables, potatoes, yams, cassava, and other potatoes), traditional farming methods use zero-cost solar energy ( ZCOE). This allows solar radiation to be delivered in units of watts per unit area (ha, acre, square meter), which results in outdoor cultivation, that is, cultivation on two-dimensional land.

  As long as it depends on ZCOE, traditional farm management must accept an efficiency of 0.1-0.5% (Table 1). One factor that reduces efficiency is that it is necessary to use soils that support plant growth as well as nutrients from soils that are not easily controlled. If you can't control it, the soil is a disadvantage, not an advantage. The main concerns of breeders when producing new varieties are specific environment (terrain) and soil mineral composition. There is a need to produce many growing varieties in order to meet market needs as much as possible rather than producing one optimal species that all fits. Nevertheless, compromises are necessary due to production cost constraints. This is the current state of agriculture that is mainly based on uncontrolled outdoor soil.

  Therefore, depending on ZCOE, producers and food producers are limited and cannot be controlled. On the other hand, this has necessitated a huge amount of underutilized resources such as two-dimensional arable land, water, fertilizer, and agricultural chemicals. Rapid deforestation was carried out to cope with the population increase from 1 billion in the 1800s to the current 7 billion. On a global scale, fearing the detrimental impact of global warming from deforestation, the government has enacted laws and regulations to limit the increase in farmland from deforestation. This is the third contradiction in the balance between supplying food to the world and securing energy.

Agricultural profitability and economic feasibility, AgriPAL
In the co-pending FSA, the law of ensuring agricultural profitability, the formula of AgriPAL, was presented and considered extensively. Formula (2) is described here.

  AgriPAL enables companies to predict the profitability and price of plant growth systems and identify efficiency bottlenecks.

  As is known in the art, agriculture is an integral part of food production: i) the sun, ii) a two-dimensional field, ie an area covered by soil that mechanically and physiologically supports plant growth. Iii) It is generally done in the form shown in FIG. 1A, including water resources for irrigation, as well as nutrients. This is called arable land with moderate amounts of sun, water and nutrients that are generally available at zero cost. Even if complementary nutrients or fertilizers are added, they are relatively low cost. As demonstrated by FSA's AgriPAL, this form of farming was profitable because the main nutrients were low or zero cost.

  In recent years, the introduction of agriculture (CEA) in indoor control environments has increased. Reference is made to US Pat. No. 3,931,695 as an example of prior art, and CEA is described (Patent Document 1). In CEA, since the growth area is protected, it is possible to control many growth parameters, thereby achieving high resource utilization efficiency at high yields. Nutrient delivery farming in soil-free hydroponics or aerial growth has increased, increasing the economic viability of many plant cultivations. FIG. 1B shows an element of CEA called the greenhouse. When using direct sunlight illuminance, CEA is the same as traditional protected farming methods with the added benefit of protection from weather and management of pesticides, nutrients and water. When adjusting the temperature, it can be cultivated repeatedly throughout the year by increasing the yield. When artificial lighting is used, the cultivation time can be extended to 24 hours per day.

  AgriPAL has shown that certain high-value-added plants are also economically viable as acceptance of this farming method progresses. Because of the additional energy consumption of heating or cooling, as well as the cost of additional infrastructure, indoor farming cannot save (advantageously) produce staple crops or biofuels. The purpose of the FSA and the present invention is an advanced aspect that the indoor farming method is feasible even for staple food crops.

  Recently, Van Gemeret et al. Taught US Pat. No. 2011/0252705, Oct. 20, 2011, which taught the three-dimensional farming system shown in FIG. 1C (Patent Document 2). The system stacks many shelves vertically and resembles the greenhouse in FIG. 1B, but with multiple layers. The salient features of this vertical farming concept are: i) high productivity per unit area; ii) plants in each layer are independent of plants in adjacent layers; iii) resources (light, nutrients) in each layer are not directly shared Iv) Limited to use only artificial light illumination; v) The ceiling height h of each layer results in low productivity per unit height of the system. Economic feasibility is limited to high value-added products such as tulips and cut flowers. As will be shown in detail later, the present invention addresses these limitations by using a cultivation layer with a network string coupled to share light and nutrients, thereby reducing the vertical height required for cultivation by 5%. To 50 coefficients.

  1D to 1H show a plant cultivation method based on the prior art with individual environments, (elements) 50a-50e, in which a plant 53 is irradiated by the sun 51. FIG. What distinguishes them is the type of cultivation medium, the plant for mechanical support, and the method of delivering nutrients to the plant. In the case of elements 50a, 50b, 50e, the soil supports the plant and delivers nutrients directly to the soil, which is absorbed by the plant roots.

  For element 50c, hydroponics well known in the art, including mechanical structure 54 (container), is used to grow one or more plants. The container is intermittently (or continuously) filled with nutrients 55 and the plant absorbs nutrients through the porous root support structure 52a. This root support structure replaces soil.

  Further, in the aerial cultivation 50 d well known in the art, the root penetrates the plant support structure 56 and reaches the bottom space 57 c, and the root is sprayed directly by the nozzle 57. This method is known to produce results that are higher than the yield in the soil and hydroponic systems because the roots are in direct contact with ambient oxygen. This method has major drawbacks such as low vertical space utilization efficiency and nozzle clogging. In all prior art, the root is nourished by a plurality of different physically separated components (individual components, not integrated components). All of these elements also nourish the roots indirectly from the bottom.

  Furthermore, the network of strings that form a multi-layer three-dimensional system is distinguished from the prior art by progressive transparency features in the multi-layer. Layer permeability can be defined as the light received from other adjacent layers (transparency) and the ability to send nutrients to adjacent layers. In addition, shoots and roots in one layer may penetrate adjacent layers. This allows roots in one layer to share the bud space of adjacent layers in the downward direction. As a result, the utilization efficiency of the vertical space is increased. The light transparency feature reduces the number of artificial lights as well as energy consumption.

  Furthermore, even if there is a slight increase in yield, it is offset by an increase in per capita demand. Outdoor, solar and soil-based farming methods are inefficient, such as inefficient demand for two-dimensional arable land, water, fertilizers, and pesticides due to low efficiency and lack of control Huge resources are required.

In Section II of the co-pending FSA, many examples highlighting the challenges associated with indoor cultivation of staple food crops are presented, and those who rely on limited prior art are more efficient
As a conclusion, it presents why this is impossible, and as a conclusion, currently, only soil-based farming methods are the staple food crops for transporting food to the world, transportation It presents a viable option when cultivating biofuels for industrial energy.

  This viable option is an ongoing reliance on zero-cost solar energy, with drawbacks and requiring enormous resources that are not being used efficiently. In addition, a limitation of outdoor farming is that agricultural producers are exposed to environmental and economic risks, unexpected crop damage from pathogens, weeds, droughts, floods, and abnormal temperature changes.

  It is an object of the present invention to teach means and methods for the advantageous use of three-dimensional space, which is an endless space, without using soil, conserving water, and as an alternative to conventional two-dimensional (2D) outdoor farming. That is. Three-dimensional agriculture according to the present invention focuses on the use of three-dimensional efficiency by teaching tools, systems and methods that compress the vertical space required for food production.

  The present invention comprises a plant body and a nutrient source to supply the plant body, the non-soil growth element for maintaining the growth of the plant body non-soil, and at least one that provides resource permeability And a permeable three-dimensional multilayer farming system.

The teaching according to the present invention of three-dimensional farming can divide the three-dimensional into a plurality of layers (multi-layers) and supply each layer with nutrients and light necessary for cultivation. The multiple layers are supported by a three-dimensional structure consisting of a master system containing subsystems, where the subsystems optimize water, light, nutrients, CO ₂ , O ₂ for a particular plant species And adjust the temperature optimally.

  The plurality of layers consists of strings of interconnected non-soil (SanSoil) growth elements (SGE), each of which germinate seeds, grow plants, support physical and structural support for plants, and water It is manufactured in one piece with multifunctionality such as supply of nutrients, light, etc., function of sensing plant environment.

  SGE strings are arranged in first, second and third spatial coordinates. These are in the form of a one-dimensional network, a two-dimensional network or a three-dimensional network supported by a multilayer structure.

  One aspect of the present invention is resource utilization efficiency such that staple crops and bio-energy are advantageously produced, and there is no “food or fuel” competition for food and energy. This is achieved by the progressive feature described herein that each SGE plant in the string network shares resources such as light, nutrients, and inner layer space. This is the multilayer permeability taught by the present invention.

  Another aspect of the present invention is to interconnect each SGE and string, make the space between the strings optically transparent and transparent, and light penetrates multiple layers to share light and save And to use it effectively. This eliminates the need to have many light sources and reduces costs.

  Another aspect of the present invention is to economically produce staple food crops by avoiding the limitations of conventional cultivation techniques in order to reduce costs.

  Another aspect of the present invention is that plant roots and stems share space and save vertical internal layer space. This means that the root of a plant in one layer enters (shares) the space of the stalk (leaf) of the underlying layer.

  Another aspect of the present invention is a fully sealed type for cultivating plants for food and energy that aims to maximize utilization efficiency and reduce costs, circulate water and nutrient resources, and includes the sealing characteristics and mechanism of the present invention. To provide a system. For example, naturally evaporated water is captured and reused. The plant cultivation environment is maintained at a desired temperature and relative humidity in order to produce maximum cultivation results. As a result, water is saved by reusing 100 to 1000 times the water wasted in conventional outdoor agriculture.

  Another aspect of the invention is the benefit of a sealed three-dimensional growth system that can avoid unpredictable weather conditions that cause loss of food production due to the climate. In a sealed 3D growth system, profitability is guaranteed because it is sterile and pathogen free.

  Another aspect of the present invention is that the sealed three-dimensional growth system is isolated from the external environment so that the above environment can be protected. This is particularly beneficial when cultivating genetically modified plant species (GMO) for experimentation and production.

  Yet another aspect of the present invention is the ability to transfer nutrients from one layer to be irrigated and from the SGE string of the layer to the underlying multiple layers of SGE strings. This is a unique supply mechanism that shows a marked difference from the well-known prior art hydroponics and aerial cultivation.

  Yet another aspect of the present invention is to use artificial lighting, preferably LEDs, instead of sunlight. Specifically, it is LED illumination that irradiates a plant with short-time pulse light of 0.1 ms to 2.5 ms at a frequency of 30 Hz to 300 Hz. The inventor has discovered that the enzyme reaction rate of plant physiology is increased 4 to 10 times by temporal control of light.

  Yet another aspect of the present invention is the control of the spatial arrangement of LED lighting in the three-dimensional growth system so that the cultivated plants receive uniform illumination.

In order to solve the conflicting challenges faced by difficult food and energy problems and humankind, innovative departure from traditional agriculture is required. Traditional agriculture is constrained by outdoor fields. This restriction is due to the fact that photosynthesis for producing biomass for food and energy is performed with solar energy, CO ₂ and water, which are zero cost. The road to solving the above-mentioned problems is to abandon farming based on outdoor soil that requires a lot of cultivated land and water resources. This new approach offers significant benefits such as overcoming uncontrollable nutrients, saving 1,000 times the water, disadvantageous conditions for cultivation and overcoming pathogens in the soil.

  The following drawings show preferred embodiments and operating principles. Here, the size, scale, shape, and presence or absence of specific necessary components not shown for brevity are well known to those skilled in the art and are not intended to be limiting or limiting.

  FIG. 7 is a diagram illustrating a state in which a plant body is cultivated using the cultivating tray 400 in the permeable three-dimensional multilayer farming system according to the embodiment of the present invention.

  He said that a joint FSA would enable an innovative new paradigm on agriculture that would solve the problems faced by humanity and secure food and plant-based energy. An important feature of the new paradigm is the understanding of the agricultural balance. This was achieved by the law of ensuring the profitability of agriculture (AgriPAL). Equation (2) is described again.

  AgriPAL enables companies to predict the profitability and price of plant growth systems and identify efficiency bottlenecks.

  In the present invention, the preferred embodiment corresponds to plant cultivation in an infinite three-dimensional space. Specifically, a three-dimensional shelf, structure, or tower with a height of 10 to 100 meters, more preferably a tower with a height of more than 100 meters to 500 meters and even 1,000 meters It is. Buildings with a height of over 500 meters already exist. It is known that the construction of a 150 meter high wind power tower is economically feasible.

  FIG. 2A exemplarily shows an overview of an indoor sansoil farming system 100 including a sansoil protected control environment 101 and a control subsystem 102, according to an embodiment of the present invention. SanSoil's protected control environment 101 is designed to be substantially impervious to pests, undesirable gases, liquids, particles, and other foreign objects. Preferably, the protected environment is best isolated for cultivation and is well isolated and protected from changes in external temperature to maintain the desired temperature that maximizes productivity.

  In certain situations, solar radiation may reinforce artificial light in photosynthetic cultivation. In such a situation, a filter is attached to the SanSoil environment 101 that removes unwanted sun wavelengths, including ultraviolet, infrared, and certain visible wavelengths.

  The sansoil environment has a structure corresponding to seed / seedling carry-in 105 and harvested carry-out 104. Preferably, the structure is designed to incorporate a suitable sealing structure, such as a load lock, to maintain aseptic or near aseptic conditions. Means for achieving the impermeability and sterility of SanSoil shelves are well known to those skilled in the art. A sunsoil environment 101 houses a plurality of sunsoil plant culture layers arranged in a three-dimensional space. The SanSoil plant layer 103 is made of an optically transparent structure and material. As a result, the plant layer 103 can share and reuse light that is not absorbed, thereby improving the light energy utilization efficiency.

  There are situations where a group of one or more interaction parameters may be adjusted and optimized simultaneously. For example, adjusting the carbon dioxide to the optimum value limited by the dark reaction enzyme density requires adjusting the light level until it is limited by the light reaction enzyme density. The optimization procedure is supported by appropriate sensors linked to controller values that need to be adjusted.

  Each SGE1 is made up of integrally manufactured structures 1a, 1b that house the plant 2, stem 2s, root 2r non-soil and are connected to nutrient sources 3, 3a. Nutrients are supplied by flowing down or sprayed in a mist toward the roots in the cup-shaped substructure. One important aspect of the present invention is the art by the spraying subsystem (or mist) that bypasses absorption from the root and supplies micron-sized fluid particles (droplets) that are absorbed directly from the leaves of the plant 2. Is a combination of well-known foliar application and the fertilization of the present invention. As shown in FIG. 3D, each SGE 1 may include a light source 4 and a sensor 5 arbitrarily and integrally.

  Also, two types of spraying systems are possible in which the first species supplies a set of nutrients to the root 2r of the plant 2 and the second species supplies different nutrients to the leaves. In addition to one or more types of sources, in certain circumstances, it is contemplated that the sources may be supplied sequentially or pulsed in time with adjustable periods and periods.

  Illumination 1h, 1j and auxiliary sensor 1g, or other resources can be placed in any direction with respect to the three spatial coordinates (FIGS. 2C-2E).

  As shown in FIG. 2F, the plurality of SGE1 are connected like a linear string 111a and connected to the supply source 3. The connection structure is designed to deliver nutrients with high conductivity to each SGE1 site. Preferably, the structure is designed for easy connection to the SGE 1 but includes automatic means that are fast and inexpensive so that long strings can be formed. Moreover, this structure is provided with the rigidity of the grade which can support the weight of a plant in the string 111a. FIG. 2G is a cross-sectional view of this string.

  In FIG. 2H, the strings 111 a and 111 b are arranged in parallel to the layer 103. And the string 111a and the string 111b are each installed in the position where SGE1 does not overlap. 2I is a view of the cross section of FIG. 2H viewed from the left side. The strings 111a, 111b, and 111c are arranged with a predetermined interval py and show an important feature of the present invention. Thereby, nutrients and light penetrating between the strings and between the layers can be shared.

  Furthermore, as shown in FIGS. 2J and 2K, by bringing the two plant layers 103a and 103b close to each other, plants in the lower plant layer 103b can share a part of the space of the upper plant layer 103a. As shown in the sectional view of FIG. 2K, the space saving situation can be recognized immediately. The space between the two plant layers is indicated by pz. Different examples where the period pz varies with plant growth, either manually or automatically, will be shown later.

  The structure of the SanSoil growth element (SGE) is more specifically shown in FIGS. 3A to 3P. The term integrated multifunction is defined as a structure consisting of at least two substructures that are integrally manufactured to perform at least two functions and are substantially permanently attached. Preferred examples of the function may include, for example, mechanical support, cultivation maintenance, germination, self-contained nutrients, self-contained light, sensing environment, and communication of nutrients with the nearest neighbor.

  The SGE1 of FIG. 3A consists of a cultivation section or substructure 1a that mechanically and physiologically supports root 2r and stem 2s growth until maturity. The partial structure 1a penetrates the opening 1c and is integrally attached to the coupling conduit 1b in the fluid communicating with the cultivation partial structure 1a. The fluid 1d flowing through the opening 1c supplies the flow 1f to the root. The cross-sectional view of the conduit 1b may have any shape as shown in FIG. 3B.

  The conduit 1b is detachably attached to at least one supply source 3. Preferably, the attachment is an immediate detachable type having a sealing function for preventing leakage. Source 3 provides the resources essential to maintain optimal plant cultivation. The resource consists of at least water and nutrients, and further conducts and delivers light by a total internal reflection mechanism well known in the optical fiber field and a backlight source well known in the liquid crystal display field. The conduit may conduct an electrical signal or electricity from the sensor to a localized LED that is integrated directly into conduit 1b.

  The conduit 1b according to FIGS. 3C and 3D connects the two SGEs 1, 1... To form the strings of FIGS. 2J and 2K described above and sends the nutrient source 3a from one SGE1 to the other SGE1. The nutrient source 3a contains a fluid, but conducts signals from the sensors 5, 5a, energizes the LED 4, and supplies light from the illumination 4b to the local plant 2.

  As shown in FIGS. 3E to 3H, the SGE 1 in the preferred embodiment is a seed support structure 1m having the function of mechanically supporting the seed 2 and creating an optimum environment for high germination rate. Including. 3E to FIG. 3H, the stem 2a and the root 2b start to grow, grow into seedlings, and finally show matured plants. Thereby, according to this preferred embodiment, for the multi-functionality such as mechanical support of seed 2 and mature plant 2a, germination, local delivery of nutrients, local delivery of light, environmental sensor, cultivation until maturity, etc. The focus is on the significance of SGE1 integration (Figure 3D).

  In addition, the multi-function integrated construction of SGE1 plays an important role of maximizing three-dimensional space utilization efficiency, and emphasizes the local self-sufficiency of each SGE1. Moreover, the difference with the plant cultivation method in the prior art mentioned above relevant to FIG. 1A-FIG. 1H is clarified.

  As shown in FIG. 3I, since the plant has the property of being oriented in the direction of light, the growth axis 6 forms an angle 6a with respect to the layer axis 1j, and this property can be advantageously used regardless of the desired direction of the plant. Can be used. Also, as shown in FIG. 3J, in other embodiments, the entire string and plane 10 may be in the direction of an angle 6b with respect to the horizontal direction 1v.

  Further, as shown in FIGS. 3K to 3M, in another embodiment, it is also preferable that the SGE1 is directed in a desired direction determined by light, and the suspended strings 11 and 12 are formed from top to bottom.

  In addition, as shown in FIG. 3N, formed in a network 13 that is a series and parallel combination of strings attached to a feed structure 14, 15 that receives nutrient sources 16, 17 from a master delivery system (not shown). SGE string interconnection provides the benefit of optimizing the system. Advantages of such an arrangement include increased system construction speed and flexibility, reduced infrastructure costs, and maximized consumable utilization efficiency.

  As shown in FIG. 3P, the monolithically manufactured, self-sufficient self-sufficient SGE1 has a plurality of desired configurations 20a to 20e in accordance with plant types and system design requirements. May be attached to the string interconnect structure 3. Those skilled in the art can manufacture other structures without departing from the interoperability of the SGE network of the present invention.

Multilayer Permeability In order to realize a completely arbitrary three-dimensional multilayer farming, the preferred embodiment includes means to maximize resource utilization efficiency. This is accomplished by sharing resources such as lighting, nutrient delivery subsystems, support structures, and space. The sharing means shown in FIGS. 4A to 4D contributes to the reduction of the system fixed cost (f) and the variable material cost (v), and secures the maximum profit related to the above-described AgriPAL equation (2).

  The definition of transparency of the present invention is the ability of a layer to consist of at least one string of SGEs that penetrates resources from a first group of adjacent transmission layers to a second group of adjacent transmission layers. The first and / or second group includes a resource delivery source. The total number of vertically arranged layers is 2 to 10, more preferably 10 to 100, and even more preferably more than 100 layers.

  The permeable features of the present invention allow sharing of resources, including water, nutrients, lighting, cooling and heating, and other shareable resources. The resource sharing allows for efficient use, thereby minimizing the cost of the final product. 3D yield or 3D productivity is measured in units of weight divided by volume and in units of time. Therefore, the resource sharing transmission means is designed to produce the maximum product weight in the most compact three-dimensional space in the shortest time. This means is shown in FIGS. 4A-4D.

  With reference to FIG. 4A, an exemplary multi-layer system 300 including at least layers 301, 302 that string a plurality of SGE1s is shown in detail in FIGS. 2G-2K. Layers 301 and 302, connection structures 301a to 301c, 302a to 302c, and SGE structure are such that light rays 305a to 305d from a light source (not shown) penetrate layers 301 and 302 to illuminate adjacent layers of stems 303s and 304s. Is substantially optically transparent. The optical transparency of the layer structure can be made of at least a transparent material selected from glass, polycarbonate, polyethylene, polypropylene, polystyrene.

  By means of achieving light transmission, at least one photogen for growing plants can be shared in multiple layers to achieve maximum efficiency of the light source. As will be appreciated, the seedlings are divided into small, wide, horizontal and vertical spaces. It takes months to fill the space between them. Until then, light that was not absorbed in one layer penetrates and is absorbed by the adjacent layer. As a result, only a few light sources are needed to illuminate many layers. This immediately reduces the initial capital investment of the light source. For example, a 100 layer (transparent) system can be covered with just one planar light source located at the top of the system. By adding a reflection system to the wall, light loss is minimized.

  In contrast, the prior art 3D farming system of FIG. 1C is supposed to use one set of light sources for each layer, suggesting how wasteful the prior art is. This further confirms the importance of the inventive permeability feature of the present invention.

  In addition to minimizing the initial fixed cost of the light source, the transmissive layer efficiently uses consumable light energy, thus reducing production fluctuation costs. Light that is not absorbed by the transmissive layers penetrates to the adjacent layers and is consumed by plants in these layers. In the prior art teaching, the light energy that the plant did not absorb was a loss that could not be recovered as a wasted resource.

  In FIGS. 4B and 4C, another type of progressive permeability feature is shown. This is invading (sharing) plant roots and stem spaces in adjacent layers 306, 307, and plant roots 303r, 304r and stems 303s, 304s (stems, branches, leaves) in one layer. About. This space sharing can achieve unprecedented vertical space compression and reduce vertical height (d) (308, 308a) by a fraction. Without this space sharing, in addition to the maximum height of the stem, the maximum height of the root is required, and the system is not compact in the vertical direction.

  Drawing 4D is a figure explaining other forms for making the adjacent layer absorb the nutrient which was not absorbed. Nutrients essential to maintain optimal cultivation of the plant are provided by a source (not shown) in space 309 that is occupied by at least multiple layers 301,302. Examples of the supply source that intermittently fills the space 309 with nutrients include a spray system, a spray system, and a drip system. Nutrients are delivered to the plant by foliar fertilization or root supply. 2F-2K show that nutrients are transferred from one layer to the next because the SGE strings in each layer are spatially separated by the amount of free space. This can minimize the number of sources and their initial cost.

  5 and 6 show an embodiment of the cultivation tray 400 as a string used in the permeable three-dimensional multilayer farming system of the present invention. In addition, FIG.5 and FIG.6 has shown a mode that the cultivation tray 400 was seen from the upper surface.

  As shown in FIG. 5, the cultivation tray 400 has an opening 403 formed in the center, and a substantially rectangular main body 401 having a notch 402 in at least a part of the opening 403, and a main body. A connecting portion 404 that communicates with both sides of 401 is defined as one unit (SGE), and a plurality of the connecting portions 404 are connected. Moreover, the wide end part 405 is formed in one end part (left side of the drawing) of the cultivation tray 400, and the narrow end part 406 in which the connection part 404 extends is formed in the other end part (right side of the drawing).

  The material of the cultivation tray 400 is formed of polyethylene terephthalate (PET), and the cross section has a substantially concave shape so that a flow path is formed. Moreover, since the material is PET, the light transmittance is high.

  FIG. 6 is a diagram showing a state in which the plant body 408 is planted together with the urethane seedbed 410 in the opening 403 of the cultivation tray 400 shown in FIG. 5 without soil (that is, non-soil). Actually, nutrients are arranged in the sunsoil environment 101 shown in FIG. 2A to maintain the growth of the plant body 408 in the flow path.

  The nutrient flow is not particularly limited, but preferably, the nutrient is supplied from the wide end 405 side and is preferably designed to flow toward the narrow end 406. The nutrients that have reached the narrow end 406 overflow from the tip of the narrow end 406 and are received by the wide end of the lower cultivation tray (not shown), and then move the cultivation tray in the same manner as described above. To go. A part of the nutrient is supplied to the plant body 408 through the notch 402, and is supplied to the lower cultivation tray (not shown) through the opening 403 or the root of the plant body 408 as it is. The nutrient is not limited to liquid but may be mist-like mist.

  The connection portion 404 of the cultivation tray 400 is preferably formed narrower than the width of the main body portion 401. Thereby, since a certain space is formed between the main body 401 and the main body 401 adjacent to each other, as shown in FIG. 4C, the vertical height (d) between the lower cultivation tray can be shortened. This makes it possible to use the space more effectively.

  FIG. 7 is a view showing a state in which a plant body is cultivated by the permeable three-dimensional multilayer farming system according to the embodiment of the present invention using the cultivation tray 400 described above. Since the cultivation tray 400 has light transmittance, the light irradiated from the upper layer part can be transmitted to the lower layer part, and light can be used efficiently.
