FIG. 2 is a schematic structural diagram of a mist culture planting system according to an embodiment of the present invention. As shown in fig. 2, the aeroponics planting system comprises an air pump 201, an ozone generator 202, a mixer 203, a booster pump 204 and a spray pipeline 205, the air pump 201, the ozone generator 202, the mixer 203 and the spray pipeline 205 are sequentially communicated through a pipeline, a first check valve 206 is arranged on the pipeline between the mixer 203 and the ozone generator 202, a water inlet is arranged on the mixer 203, a first stop valve 207 is arranged on the pipeline connected with the water inlet, a second stop valve 208 is arranged on the pipeline between the mixer 203 and the spray pipeline 205, the water inlet end of the booster pump 204 is communicated with the mixer 203, and the water outlet end of the booster pump 204 is communicated with the spray pipeline 205.
The technical scheme of the embodiment is described below by combining a specific use method of the aeroponic cultivation system:
specifically, when the first stop valve 207 is in the closed state, the fog cultivation system has two working modes, namely an oxygen increasing mode and a disinfection mode.
In the oxygen increasing mode, the air pump 201, the first check valve 206 and the second stop valve 208 are opened, and the ozone generator 202 is closed. The air pump 201 pumps air into the pipe, which flows directly from the ozone generator 202 without any treatment, after which the air passes in turn through a first check valve 206, a mixer 203 and a second shut-off valve 208 into a spray line 205, delivering outside air to the spray space through the spray line 205. The oxygen content in the spraying space is increased, the oxygen aeration of the plants in the spraying space is realized, the growth environment of the plant root system is improved, the situation of plant root system necrosis is reduced, and the absorption of the plant root system to nutrition is facilitated.
In the sterilization mode, the air pump 201, the ozone generator 202, the first check valve 206 and the second check valve 208 are opened, and the air pump 201 pumps air into the pipe. After the air enters the ozone generator 202, ozone gas is generated under the action of the ozone generator 202. The gas generated by the ozone generator 202 is a mixed gas containing ozone, the product of the concentration of the ozone in the mixed gas and the total air amount entering the ozone generator 202 is the ozone output of the ozone generator 202, and the specification model of the ozone generator 202 is expressed by the ozone output, so that the corresponding model of the ozone generator 202 can be selected according to actual needs. The mixed gas enters the spray line 205 through the first check valve 206, the mixer 203 and the second stop valve 208 in sequence, and the ozone mixed gas is delivered to the spray space through the spray line 205. Realizes the disinfection of the spraying space and the plant root system, reduces the breeding of germs and viruses in the spraying space, and improves the growth environment of the plant root system. In addition, because the mixed gas also contains partial oxygen, the oxygen content in the spraying space can be increased, the necrosis rate of the plant root system in the closed spraying space is reduced, and the absorption of the plant root system to nutrition is facilitated.
Specifically, when the first stop valve 207 is in an open state, the fog cultivation system has three working modes, namely a water supply mode, a water supply oxygenation mode and a water supply disinfection mode.
In the water supply mode, the booster pump 204 is turned on, and the air pump 201, the ozone generator 202, and the second shutoff valve 208 are turned off. Water passes through the first stop valve 207 and the mixer 203, and enters the spraying space through the spraying pipeline 205 under the action of the booster pump 204, so that water supply to the root system of the plant is realized.
In the water supply oxygenation mode, the air pump 201, the mixer 203, the booster pump 204 and the first check valve 206 are opened, and the ozone generator 202 and the second stop valve 208 are closed. The air pump 201 pumps air into the conduit, which flows directly from the ozone generator 202 without any treatment, after which the air in turn enters the mixer 203 through the first check valve 206, mixing with the water entering the mixer 203 through the first check valve 207. After thorough mixing, the air is partially dissolved in the water, mostly in the form of microbubbles. Under the action of the booster pump 204, water is conveyed to the spraying space through the spraying pipeline 205, air bubbles in the water are released into the spraying space, water is supplied to the plant root system and the spraying space, and meanwhile, the oxygen content of the surface of the plant root system and the oxygen content of the spraying space are increased. The necrosis rate of the plant root system in the closed spraying space is reduced, and the absorption of the plant root system to water and other nutrient substances is promoted.
In the water supply sterilization mode, the air pump 201, the ozone generator 202, the mixer 203, the pressurizing pump 204, and the first check valve 206 are opened, and the second check valve 208 is closed. The air pump 201 pumps air into the pipeline, and after the air enters the ozone generator 202, ozone mixed gas is generated under the action of the ozone generator 202. The ozone mixed gas enters the mixer 203 through the first check valve 206 in turn, and is mixed with the water entering the mixer 203 through the first check valve 207. After thorough mixing, ozone disinfects the water source. The disinfected water is delivered to the spray space via a spray line 205 by means of a booster pump 204. Not only avoids harmful substances such as germs and viruses from being brought into the spraying space and the plant root system due to the water source water quality problem when supplying water to the plant root system, but also can disinfect the spraying space and the plant root system, thereby improving the growth environment of the plant root system. Meanwhile, the mixed gas also contains partial oxygen, so that the oxygen increasing effect on the spraying space can be achieved.
According to the aeroponic cultivation system provided by the embodiment of the invention, air is pumped into a system pipeline through the air pump 201, or ozone mixed gas generated by the ozone generator 202 is conveyed to the system pipeline. On one hand, under the state that the first stop valve 207 is closed, the air or ozone mixed gas is conveyed to the aeroponics space where the plant root system is located, so that the oxygen increasing or the disinfection of the aeroponics space is realized; on the other hand, in a state where the first stop valve 207 is opened, the water mixed with the air or the ozone mixed gas in the mixer 203 is supplied to the spray space where the plant roots are located through the booster pump 204. The growth environment of the plant root system is improved, the plant root system or the spraying space is oxygenated or disinfected while water is supplied to the plant, the absorption of the plant root system to nutrient substances is promoted, the breeding of germs and viruses of the plant root system is reduced, and the crop yield is improved.
Optionally, the mixer 203 is an ejector to realize strong mixing and ejection of water flow and air or ozone gas, so that the water source and the air or ozone gas are uniformly and completely stirred, the dissolving efficiency of the ozone gas is improved, the water disinfection efficiency is improved, the generated bubbles are many and fine, and the air can be effectively brought into the spray space.
