Description
Technical Field
The invention relates to an aerosol cultivation system, in particular to an aerosol cultivation system capable of automatically controlling nutrient solution components and inhibiting bacteria in the environment.
Background
The aerial fog cultivation is a soilless cultivation mode, and belongs to a plant cultivation mode without soil, which is the same as the modes of matrix cultivation, hydroponic cultivation and the like. The substrate cultivation itself has the strict conditions of sterile environment, limited plant growth, substrate replacement and the like. Compared with hydroponic cultivation, the aeroponic cultivation has the advantages of saving water and fertilizer, and solving the problem of insufficient dissolved oxygen in water. The development limit of the aeroponic cultivation is less, the root system development is good, the agricultural yield quality is high, and the aeroponic cultivation becomes a cultivation technology with great development potential in the future.
However, the lack of soil as a buffer and the lack of symbiotic bacteria in the soil make the aeroponics quite sensitive to environmental temperature and humidity, absorbable and utilizable nutrients and pH. On the other hand, plants generally secrete secondary metabolites into the soil to exert antibacterial and bacteriostatic effects, but in aeroponics plants reduce secretion of secondary metabolites to avoid the secondary metabolites staying on the roots to hinder respiration and even poison the body.
At present, a nutrient solution tank is commonly arranged in the industry, fertilizer powder is added into water, and the water is uniformly mixed and sprayed to plant root systems through pipelines. This approach consumes a lot of labor and is subject to human error. And the same fertilizer is applied in different seasons, so that the plant growth potential can not be well stimulated. Then, in order to recycle the nutrient solution, the nutrient solution tank recovers the coagulated nutrient solution spray. The process of spraying and recycling the nutrient solution is easy to grow bacteria, and the bacteria consume a large amount of nutrient components and cause damage to plants which reduce secretion of secondary metabolites.
Thus, there is a need in the art for a more complete, balanced system to reduce the amount of manual work and the threat of disease.
Disclosure of Invention
In view of the above, the invention aims to provide an automatic aerosol cultivation system which has the advantages of simple structure, convenient operation and convenient maintenance, can overcome the defects of the prior art, can automatically adjust nutrients, prepare nutrient solution, supply water and the nutrients and sterilize.
In order to achieve the above purpose, the invention discloses an automatic aerosol cultivation system, which is applied to crop planting of a plant bed, wherein the plant bed is divided into a root space by a plant plate area, and is characterized in that the system comprises:
a nitrate liquid tank for containing and outputting a nitrified nitrogen liquid;

There are a number of embodiments of the present invention. The components of the same name and number in each embodiment are in principle identical in structure, operation and function, and may be reasonably combined or modified in a manner that will be readily understood by those skilled in the art, unless otherwise indicated. Therefore, the components already described will not be described in detail in the following embodiments.
The nitrified nitrogen liquid in the present invention is a liquid in which nitrate is dissolved, the nitrate having nitrate (NO 3 (-) is, for example, calcium nitrate (Ca (NO) 3 ) 2 ) Or potassium nitrate (KNO) 3 ) Etc. The ammonium nitrogen liquid in the invention refers to liquid dissolved with ammonium salt, the ammonium nitrogen can also be called ammonium nitrogen, and ammonium salt has ammonium radical (NH) 4 + ) For example ammonium chloride (NH) 4 Cl), ammonium sulfate ((NH) 4 ) 2 SO 4 ) Ammonium bicarbonate (NH) 4 HCO 3 ) Urea (CN) 2 H 4 O), and the like.
Referring to fig. 1, fig. 1 is a functional block diagram of an automated aerosol-generating system according to an embodiment of the invention. The automatic aerosol cultivating system 1 is applied to crop planting of the planting bed 2. The plant bed 2 is divided into root spaces 20 by plant plates. The automated aerosol generating system 1 comprises an ammonium nitrogen tank 111, a nitrate tank 112, a first mother liquor tank 11, a nutrient solution mixing tank 16, a spray line device 180 and a controller 10. The ammonium nitrogen liquid tank 111 is used for containing and outputting an ammonium nitrogen liquid. The nitrate tank 112 is used for containing and outputting mononitrified nitrogen liquid. The first mother liquor tank 11 is connected to the nitrate liquor tank 112 and the ammonium nitrogen liquor tank 111, and is used for receiving and mixing the nitrified nitrogen liquor and the ammonium nitrogen liquor to form and output a first mother liquor. The nutrient solution mixing tank 16 is connected to the first mother liquor tank 11 for receiving the first mother liquor, diluting the first mother liquor to form and output a nutrient solution. The spray line assembly 180 communicates with the nutrient solution mixing tank 16 and extends to the root space 20 for spraying the nutrient solution. The controller 10 is connected to the nitrate liquid tank 112 and the ammonium nitrogen liquid tank 111 for controlling the output of the nitrate liquid tank 112 and the ammonium nitrogen liquid tank 111 to adjust the component ratio of the first mother liquor.
The crop species are not limited to herbaceous plants, woody plants or aquatic plants, and there are commercial crops such as potatoes, tomatoes, strawberries and the like. The support of the plants may rely on the plant plates. The root of the plant is mainly located in the root space 20 below the plant plate, and the stem and leaf of the plant are mainly located in the stem and leaf area on the frame of the plant plate. The periphery of the root space 20 is covered by foam plates and black cloth, so that the effects of moisture preservation and heat preservation are achieved.
The ammonium nitrogen solution in the ammonium nitrogen solution tank 111 and the nitrate nitrogen solution in the nitrate solution tank 112 can be concentrated solutions with the concentration of more than 10 times of the concentration of elements required by plants, and the concentrated solutions can be diluted into the concentration required by the plants in the process of preparing nutrient solutions. The first mother liquor tank 11 may be designed so that the powdery compound is prepared in the form of a solution in advance, as a transition period before the powdery compound is prepared as a nutrient solution. The first mother liquid with higher concentration can be placed for a long time without easy deterioration until the nutrient solution amount of the nutrient solution mixing tank 16 is insufficient, and then the first mother liquid is output to the nutrient solution mixing tank 16 to form a plant proper solution with lower concentration. The spray line device 180 includes a plurality of spray heads disposed in the root space 20 for spraying the atomized nutrient solution according to a predetermined time, duration and water quantity.
The first mother liquor contains urea (ammonium nitrogen), calcium nitrate (nitrified nitrogen), potassium nitrate (nitrified nitrogen), calcium chloride and the like, and mainly provides nitrogen sources required by plants. The applicant of the present invention found that plants absorb both nitrogen fertilizers of the involutory nitrogen and the ammonium nitrogen to different extents in different seasons. Therefore, an ammonium nitrogen liquid tank 111 and a nitrate liquid tank 112 are arranged in the system at the upstream of the first mother liquid tank 11, and are uniformly controlled by the controller 10, so that the nitrogen fertilizer proportion in the first mother liquid can achieve the effects of settable switching and automatic adjustment. The user can set the nitrogen fertilizer proportion today according to the weather forecast, or the system can automatically arrange the nitrogen fertilizer proportion today according to the weather forecast, or the system can automatically adjust the nitrogen fertilizer proportion today according to the following embodiment.
Referring to fig. 2, fig. 2 is a functional block diagram of an automated aerosol-generating system according to another embodiment of the invention. In addition to the components described above, the automated aerosol-generating system of the present embodiment further comprises a thermometer 101 and a hygrometer 102. The thermometer 101 is coupled to the controller 10 for detecting the ambient temperature and outputting a temperature signal. The hygrometer 102 is coupled to the controller 10 for detecting the ambient humidity and outputting a humidity signal. Wherein the controller 10 adjusts the component proportion of the first mother liquor according to the temperature signal and the humidity signal, thereby realizing automatic component proportion adjustment. The thermometer 101 and the hygrometer 102 are mainly installed in the root space 20, and the ambient temperature mainly refers to the ambient temperature of the root space 20.
Specifically, if the thermometer 101 detects an increase in the ambient temperature, the controller 10 increases the output ratio of the ammonium nitrogen liquid tank 111, decreases the output ratio of the nitrate liquid tank 112, and adjusts the increase in the ratio of the ammonium nitrogen liquid to the nitrified nitrogen liquid in the first mother liquid. Similarly, if the ambient temperature decreases, the controller 10 adjusts the ratio of the ammonium nitrogen liquid to the nitrified nitrogen liquid in the first mother liquid to decrease. Therefore, the plants can absorb more nitrogen sources which are preferred to be utilized at present when the temperature is changed.
If the hygrometer 102 detects that the ambient humidity is reduced, the controller 10 reduces the output ratio of the ammonium nitrogen liquid tank 111, increases the output ratio of the nitrate liquid tank 112, and adjusts the ratio of the ammonium nitrogen liquid to the nitrified nitrogen liquid in the first mother liquid to increase. Similarly, if the ambient humidity increases, the controller 10 adjusts the proportion of the ammonium nitrogen liquid to the nitrified nitrogen liquid in the first mother liquid to decrease.
For example, when the ambient humidity exceeds 90%, the controller 10 controls the spray line device 180 to shorten the spraying time period for spraying the nutrient solution (for example, 60 seconds to 30 seconds), or lengthen the interval time period for not spraying the nutrient solution (for example, 15 minutes to 30 minutes). When the ambient humidity is lower than 50%, the sensor 10 controls the spray line device 180 to extend the spray period of spraying the nutrient solution, or to shorten the interval period of not spraying the nutrient solution, or to additionally spray the nutrient-free water from the water tank.
FIG. 3 is a functional block diagram of an automated aerosol generating system according to yet another embodiment of the present invention. In this embodiment, the automated aerosol-generating system 1 further comprises a second mother liquor tank 12 and a third mother liquor tank 13. The second mother liquor tank 12 is connected with the nutrient solution mixing tank 16, and is used for containing and outputting a second mother liquor to the nutrient solution mixing tank 16, wherein the second mother liquor contains potassium mono-phosphate, potassium sulfate, magnesium sulfate and the like, and mainly provides multiple elements (phosphorus, potassium, magnesium and sulfur) required by plants. The third mother liquor tank 13 is connected with the nutrient solution mixing tank 16, and is used for containing and outputting a third mother liquor to the nutrient solution mixing tank 16, wherein the third mother liquor contains chelated iron (EDTA-Fe), boric acid, zinc sulfate, copper sulfate, manganese sulfate, ammonium molybdate and the like, and is mainly trace elements (iron, manganese, boron, molybdenum, copper, zinc, cobalt and the like) required by plants.
Because the compound mixed solution is easy to generate interaction or precipitation under long-term placement, each compound is prepared into mother liquor, and a large amount of equipment and control cost are required. Therefore, the invention selects proper compounds according to plant demands, and divides the compounds into three kinds, each kind is configured into mother liquor, so that the configured mother liquor is relatively not easy to react or deteriorate. The three mother solutions can be placed for a long time, so that the quality management and the equipment management are balanced.
The components in the first mother liquor, the second mother liquor and the third mother liquor can be concentrated solution with concentration which is more than 5 times of the concentration of elements required by plants, and the concentrated solution is diluted into the concentration required by the plants by water in the process of preparing the nutrient solution. The automated aerosol-generating system 1 further comprises a water tank 14 connected to the nutrient solution mixing tank 16 for containing and delivering water to the nutrient solution mixing tank 16. The nutrient solution mixing tank 16 receives water, the first mother liquor, the second mother liquor, and the third mother liquor to form and output the nutrient solution. The controller 10 controls the output amounts of the first mother liquor tank 11, the second mother liquor tank 12, the third mother liquor tank 13, and the water tank 14 to adjust the component ratio of the nutrient solution.
FIG. 4 is a functional block diagram of an automated aerosol generating system according to yet another embodiment of the present invention. In this embodiment, the automated aerosol-generating system 1 further comprises a pH meter 105, an acid tank 151 and a base tank 152. The ph meter 105 is disposed in the nutrient solution mixing tank 16, and is used for detecting the ph of the nutrient solution and outputting a ph signal. The acid tank 151 is connected to the nutrient solution mixing tank 16, and is used for containing and selectively outputting an acid solution to the nutrient solution mixing tank 16. The alkaline solution tank 152 is connected to the nutrient solution mixing tank 16, and is used for containing and selectively outputting an alkaline solution to the nutrient solution mixing tank 16. The controller 10 controls the output of the acid tank 151 and the alkali tank 152 according to the pH value signal to adjust the pH value of the nutrient solution.
The ratio of ammonium nitrogen to nitrate nitrogen in the first mother liquor outputted from the first mother liquor tank 11 changes with the climate, and the pH value of the nutrient solution also fluctuates. Plants are more likely to develop undesirable growth conditions in nutrient solution environments having a pH of 5 or below or above. When the pH meter 105 detects that the pH value of the nutrient solution is higher than the threshold value, the controller 10 controls the acid solution tank 151 to output acid solution to the nutrient solution mixing tank 16, so as to reduce the pH value; when the pH meter 105 detects that the pH value of the nutrient solution is lower than the threshold value, the controller 10 controls the alkali liquid tank 152 to output alkali liquid to the nutrient solution mixing tank 16, so as to increase the pH value.
FIG. 5 is a functional block diagram of an automated aerosol generating system according to yet another embodiment of the present invention. In this embodiment, the automated aerosol-generating system 1 further comprises a liquid collection conduit 181 and an ultraviolet light device 19. The liquid collecting and conveying pipeline 181 is communicated with the nutrient solution mixing tank 16 and extends to the bottom of the root space 20 to recover secondary nutrient solution condensed in the root space 20. The ultraviolet light device 19 is disposed beside the liquid collecting and transporting pipeline 181, and is configured to emit ultraviolet light to a portion of the liquid collecting and transporting pipeline 181 to irradiate the secondary nutrient solution in the liquid collecting and transporting pipeline 181.
The secondary nutrient represents the nutrient recovered from the liquid collection line 181, but does not represent the only two times, but may be multiple times, in which the ingredients circulate between the nutrient mix tank 16 and the root space. The ultraviolet light emitted by the ultraviolet light equipment 19 cannot irradiate the root space 20, so that the injury to the plant roots is avoided. The uv light device 19 reduces the risk that the secondary nutrient solution will carry microorganisms such as viruses, bacteria, mold, etc. from the root space 20 back to the nutrient solution mixing tank 16.
FIG. 6 is a functional block diagram of an automated aerosol generating system according to yet another embodiment of the present invention. The automated aerosol generating system 1 further comprises a disinfectant tank 17 connected to the spray line device 180 for containing and delivering a disinfectant. Wherein, the controller 10 controls the disinfectant tank 17 to output for a predetermined time, so that the spray line device 180 sprays the disinfectant in the root space 20.
The disinfectant can be sodium hypochlorite (NaClO), chlorine dioxide (ClO) 2 ) Hypochlorous acid (HClO) or other known disinfectants. The disinfectant can effectively inhibit viruses or microorganisms in the root space 20 and the liquid collection and delivery pipeline 181. Considering that the physiological activities of the plants are slowed during the evening, the response to the sterilizing fluid is slight, and the controller 10 may be configured to briefly spray the sterilizing fluid during the evening, particularly for a period of time between eight and ten nights. After spraying the disinfectant, no nutrient solution is sprayed until early morning, so that the disinfectant is fully acted. In the early morning, the plants gradually recover physiological activities, and can be sprayed with water to wash away disinfectant, and then with nutrient solution.
The liquid collecting and delivering pipeline 181 further comprises a three-way valve device (not shown), wherein a first end of the three-way valve device is communicated with the nutrient solution mixing tank 16, a second end of the three-way valve device extends to the root space 20, and a third end of the three-way valve device is communicated with a disinfectant discharging area 3. When the spraying pipeline device 180 sprays the disinfectant, the controller 10 adjusts the three-way valve device to close the route of the liquid collecting and conveying pipeline 181 to the nutrient solution mixing tank 16, and opens the route of the liquid collecting and conveying pipeline 181 to the disinfectant discharging area 3, and the process continues until the next spraying or before the spraying of the nutrient solution. In this way, the disinfectant can be prevented from being led to the nutrient solution mixing tank 16 to influence the nutrient solution components and cause repeated damage to plants. When the spray line device 180 sprays nutrient solution, the controller adjusts the three-way valve device to open the liquid collection and delivery pipeline 181 to the nutrient solution mixing tank 16 and to close the liquid collection and delivery pipeline 181 to the disinfectant discharge area 3. The sterilizing fluid discharge area 3 may also be connected to the sterilizing fluid tank 17, whereby the sterilizing fluid may also be reused.
The above-mentioned various tanks can be used to achieve the purpose of selective liquid communication and output through pumps, water pipes, water gates and valves. The various tank bodies can comprise a water level gauge for monitoring the liquid amount in the tank, and when the liquid amount in the tank is insufficient, the upstream tank body supplies the precursor solution or gives an alarm.
FIG. 7 is a functional block diagram of an automated aerosol generating system according to yet another embodiment of the present invention. The present embodiment describes that the foregoing components, devices, and apparatuses may cooperate. The controller 10 receives data from the thermometer 101 and the hygrometer 102, and controls the ammonium nitrogen liquid tank 111 and the nitrate liquid tank 112 to output ammonium nitrogen liquid and nitrified nitrogen liquid to the first mother liquid tank 11. The controller 10 monitors the water level in the nutrient solution mixing tank 16, and controls the output of one of the mother liquor tanks 11, 12, 13, 14 to adjust the ratio of the ingredients of the nutrient solution. After mixing the nutrient solutions, the controller 10 selectively outputs the acid solution and the alkali solution from the acid solution tank 151 and the alkali solution tank 152 to the nutrient solution mixing tank 16 according to the data of the pH meter 105, and adjusts the pH to an appropriate value.
The controller 10 drives the nutrient solution mixing tub 16 to output nutrient solution at predetermined times and spray the nutrient solution in the root space 20 by the spray line assembly 180. The condensed secondary nutrient solution flows back to the nutrient solution mixing tank 16 through the liquid collecting and delivering pipeline 181, and ultraviolet light is irradiated and disinfected by ultraviolet light equipment in the process.
The controller 10 drives the disinfectant tank 17 to output disinfectant at a predetermined time, and the disinfectant is sprayed and sterilized in the root space 20 by the spray line device 180. At the same time, the controller 10 switches on the route from the liquid collecting and transporting pipeline 181 to the sterilizing liquid discharging area 3, and closes the route from the liquid collecting and transporting pipeline 181 to the nutrient solution mixing tank 16. The condensed sterilizing fluid is discharged to the sterilizing fluid discharge section 3 through the fluid collecting and transporting line 181.
In summary, the automated aerosol-generating system of the present invention can be configured with a suitable and large amount of mother liquor for a long-term stable nutritional source. Further, nitrate liquid and ammonium nitrogen liquid are mixed into mother liquid in a separating tank, and the mother liquid can be proportionally adjusted according to temperature, humidity, weather forecast and the like, so that a more proper nitrogen source is provided for plants. The invention provides a nutrient solution with an acid-base regulating function for providing proper pH value. By utilizing the liquid collecting and conveying pipeline for recycling the nutrient solution and the ultraviolet light equipment, the fertilizer cost can be reduced and the risk of recycling the liquid pollution can be reduced. The disinfection solution is sprayed regularly to effectively inhibit the propagation of plant root system mixed bacteria, and finally, a three-way valve device is utilized to ensure that a single liquid collecting and conveying pipeline can be used for recycling the nutrient solution and the disinfection solution, so that the waste of the nutrient solution or the excessive damage of the disinfection solution to plants is avoided.
From the foregoing detailed description of the preferred embodiments, it is intended to more clearly describe the nature and spirit of the invention, but not to limit the scope of the invention by the above disclosed preferred embodiments. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the scope of the invention as defined by the appended claims.
