Technical Field

The invention relates to the technical field of plant cultivation, in particular to a planting device and method capable of regulating humidity.

Background

The plant factory is in a relatively closed environment, the evaporation of the plant, the evaporation of the culture medium and the nutrient solution enables the air humidity to be large, when the air humidity is high, the evaporation capacity of the plant leaves is small, the absorption of the root to the nutrient solution is reduced, the photosynthesis of the plant is affected, and the yield of photosynthetic products is reduced. When the air humidity is low, the transpiration rate of the plant leaves is increased, and when the transpiration rate is serious, the water supply of the plant roots is insufficient, the air hole conductivity is reduced, the air hole is closed, the extracellular carbon dioxide exchange amount is reduced, and the accumulation of photosynthetic products is reduced; therefore, the influence of humidity on the plant cultivation is not negligible, and it is necessary to control the humidity in the plant factory when the plant cultivation is performed, particularly when the plant cultivation is performed in the plant factory.

There is a great deal of research in the prior art concerning humidity control in plant cultivation, for example:

the invention patent with publication number CN111052961A discloses temperature and humidity regulation equipment in non-test tube rapid propagation of plants, which comprises a seedling raising chamber, wherein seedlings are cultivated on the bottom surface of the seedling raising chamber, an air conditioner external machine and a water tank are arranged outside the seedling raising chamber, a ventilation main pipe of the air conditioner is arranged above the seedling raising chamber, temperature and humidity regulation heads are uniformly distributed on the lower side of the ventilation main pipe, an interface of a spray head on the temperature and humidity regulation heads is communicated with the water tank through a water pipe, a water pump for pumping water is arranged in the water tank, a thermometer and a hygrometer are arranged on the front side wall and the rear side wall of the seedling raising chamber, the temperature and humidity regulation heads comprise a shell and a regulating cylinder, the regulating cylinder is used for regulating the temperature of the first ventilation cavity and the second ventilation cavity in a cylinder shape, and the temperature and humidity of the ventilation main pipe are regulated by the air conditioner, and the spray head and active carbon are used for regulating the temperature and the humidity of the seedling raising chamber to be always in an optimal temperature and humidity range of the seedlings, and non-test tube rapid propagation task of the seedlings is realized.

Ventilation and dehumidification are adopted in a large quantity by the prior art because of low cost, but the airflow generated by the ventilation system in the prior art is often reduced in flow speed at the position close to plants due to blocking of the plants, particularly under the condition of dense planting of the plants, the ventilation among blades is often unsmooth due to mutual shielding of the plants, high-humidity and high-temperature air retention on the surfaces of the blades is caused, the transpiration effect of the plants is reduced or even stopped, and the plants are difficult to transport calcium ions to the blades, so that fever and heart disease are induced.

In order to solve the defects in the prior art, the invention provides a planting device and a planting method capable of regulating and controlling humidity.

Furthermore, there are differences in one aspect due to understanding to those skilled in the art; on the other hand, since the applicant has studied a lot of documents and patents while making the present invention, the text is not limited to details and contents of all but it is by no means the present invention does not have these prior art features, but the present invention has all the prior art features, and the applicant remains in the background art to which the right of the related prior art is added.

Disclosure of Invention

The existing plant factory, greenhouse and other indoor plant planting systems can adjust the environmental humidity for plant growth, and the problem that plants generate lesions due to the too high or too low planting environment is avoided. The existing indoor plant planting systems mostly regulate and control the plant planting environment in a mode of presetting a humidity threshold, namely, humidification is carried out when the plant planting environment is lower than the preset humidity threshold; dehumidifying when the plant growing environment is lower than a preset humidity threshold value. The high tightness of plant factories is one of the main reasons for the high humidity of the plant growing environment. In order to reduce the indoor excessive humidity, the existing plant factories mostly adopt a ventilation method, and outdoor dry air is sent into the indoor space, and the indoor high-humidity air is discharged to reduce the indoor humidity. Since the optimal humidity required by the plants at different growth stages is different, and the environmental humidity requirements of different plants are also different. The prior art cannot meet the humidity requirements of different plants in different growth stages, and a manager is required to set a humidity threshold according to the plant types and the growth states of the plants. Because hysteresis exists in the artificial observation of the growth stage of the plant, the method can not timely adjust the humidity in the planting environment according to the growth stage of the plant, which is unfavorable for the growth of the plant. The ventilation system of the existing plant factory often causes the reduction of the flow rate of air generated by the ventilation system at the position close to plants due to the blocking of the plants, and particularly under the condition of dense planting of the plants, the air flow among the blades is insufficient due to the mutual shielding of the plants, so that the air on the surfaces of the blades is detained at high humidity and high temperature, the air holes of the plants are closed, and the transpiration effect is reduced or even stopped. After the transpiration is reduced, calcium ions of the root system are difficult to transport to the canopy leaves, so that the new leaves of the plants are deficient in calcium, and the burn and heart disease occurs.

Therefore, how to adjust the humidity of the growing environment of plants according to the growing state of the plants and how to reduce the incidence of heart burn when ventilation and dehumidification are adopted is a technical problem which the present invention is intended to solve.

Aiming at the defects of the prior art, the invention provides a planting device capable of regulating humidity, which at least comprises a shell, wherein the inner cavity of the shell forms a plant planting space. The planting device further comprises a spraying module, an air flow circulation module and a control module.

The control module determines the working modes of the spraying module and the air flow circulation module based on the plant growth state and the humidity in the planting device so as to adjust the humidity in the planting device, thereby ensuring that the humidity of the environment where the plants in the planting device are located is suitable for the growth state of the plants.

Preferably, the invention obtains the growth state of the plant, determines the humidity suitable for the growth of the plant, then judges whether the existing growth environment humidity is suitable for the growth of the plant, and adjusts the environment humidity if the existing growth environment humidity is not suitable for the growth of the plant, so that the environment humidity is always at the humidity suitable for the growth of the plant. Preferably, the present invention ensures sufficient air flow between the plant leaves by the first air flow and the second air flow flowing transversely in the inner cavity of the housing when dehumidifying, thereby reducing the incidence of heart burn while reducing the humidity.

Preferably, when the culture medium belonging to plant seeds and root growth environments is humidified, the spraying module enters a first spraying mode and sprays the solution with larger atomized particles, so that the gravity borne by the atomized particles is far greater than the air resistance borne by the atomized particles, and the solution with larger atomized particles can fall to the bottom of the planting device as soon as possible to increase the humidity of the culture medium, and the situation that the atomized particles cannot fall to the culture medium later due to the air resistance borne by the atomized particles caused by the too small atomized particles is avoided.

Preferably, when humidifying the air belonging to the plant stem and leaf growing environment, the spraying module enters a second spraying mode, and sprays the solution with smaller atomized particles, so that the air resistance of the atomized particles can effectively prolong the air stagnation time of the atomized particles, and the air humidity is rapidly increased.

According to a preferred embodiment, the airflow circulation module comprises at least a plurality of first ventilation openings arranged on the side wall of the shell and a plurality of second ventilation openings arranged on the side wall opposite to the side wall where the first ventilation openings are arranged. Preferably, the air flow circulation module generates a first air flow which flows transversely in the inner cavity of the shell through the first ventilation opening, and the first air flow leaves the planting device through the second ventilation opening after flowing out of the first ventilation opening and passing through the inner cavity of the shell.

Preferably, the invention can increase the airflow velocity of the first ventilation opening and the second ventilation opening below the plant canopy according to the height of the plant, thereby increasing the airflow velocity between plant leaves, taking away the high-humidity and high-temperature air on the surfaces of the leaves, ensuring that the plant keeps normal transpiration and further reducing the incidence rate of the plant fever and heart disease.

According to a preferred embodiment, the control module collects plant growth status and humidity data within the planting device via a camera and a humidity sensor, respectively. Preferably, the camera and the humidity sensor transmit the collected plant growth state and humidity data in the planting device to the control module in a wired and/or wireless mode.

Preferably, the camera and the humidity sensor are in communication connection with the control module in a wired or wireless mode. The control module compares the image acquired by the camera with the data in the database to determine the type of the corresponding plant and the growth stage of the plant in the growth period, and obtains the environmental humidity value of the plant in the growth stage, wherein the environmental humidity value can promote the growth of the plant. The control module compares the humidity value of the actual plant growth environment obtained through the humidity sensor with the environment humidity value for promoting plant growth to determine whether to adjust the humidity of the plant growth environment, so that the dynamic adjustment of the humidity of the plant growth environment is realized. Preferably, the humidity value at which the plant can promote its growth at a certain stage of growth may be a constant value or may be a humidity range.

According to a preferred embodiment, the control module adjusts the humidity of the plant growing environment in the planting device at least including a humidifying operation. Preferably, the humidification operation is performed such that, in the case where the humidity of the growing environment of the plant in the planting device is lower than the proper humidity for growth thereof, the control module generates a humidification command sent to the spraying module, and in response to receipt of the humidification command, the spraying module sprays an atomized solution to the growing environment of the plant in the planting device to increase the humidity of the growing environment of the plant.

Preferably, the dehumidifying operation is performed such that, in case that the humidity of the growing environment of the plant in the growing apparatus is higher than the proper humidity for growth thereof, the control module generates a dehumidifying command to the air circulation module, and in response to receipt of the humidifying command, the air circulation module increases the air flow rates of the first and second ventilation openings near the growing environment of the plant so that the flow rate of the first air flow near the growing environment of the plant is accelerated, thereby taking the moisture of the growing environment of the plant away from the growing apparatus to reduce the humidity of the growing environment of the plant.

According to a preferred embodiment, the airflow circulation module further comprises a plurality of third air vents arranged at the bottom of the inner cavity of the shell. Preferably, the airflow circulation module forms a second airflow in the inner cavity of the shell opposite to the spraying direction of the atomized solution of the spraying module through a plurality of third air inlets, and the second airflow and the first airflow can leave the inner cavity of the shell from the second air inlets to take away moisture in the planting device, so that the humidity of the plant growing environment is reduced.

Preferably, a plurality of third air vents arranged at the bottom of the planting device can generate second air flow along the direction from the root system of the plant to the canopy of the plant, and as the second air flow has less blocking of the air flow by the plant, compared with the mode that the air with high humidity and high temperature on the surface of the plant blade is taken away by the first air flow, the second air flow can better take away the air with high humidity and high temperature on the surface of the plant blade, thereby reducing the incidence probability of the plant heart disease.

According to a preferred embodiment, the spray module is connected with at least a first infusion tube for transporting the pesticide and the insecticide liquid and a second infusion tube for transporting the aqueous solution for increasing the humidity of the plant growing environment.

Preferably, when humidifying the air belonging to the plant stem and leaf growing environment, the spraying module 110 enters the second spraying mode to spray the solution with smaller atomized particles, so that the air resistance of the atomized particles can effectively prolong the air stagnation time of the atomized particles, and thus the air humidity is rapidly increased.

Preferably, the airflow circulation module 120 includes at least a plurality of first vents 121 provided at a sidewall of the housing 101 and a plurality of second vents 122 provided at a sidewall opposite to the sidewall where the first vents 121 are located.

Preferably, the present invention can increase the airflow velocity of the first ventilation opening 121 and the second ventilation opening 122 located below the canopy of the plant according to the height of the plant, thereby increasing the airflow velocity between the plant leaves, taking away the air with high humidity and high temperature on the leaf surfaces, so that the plant keeps normal transpiration, and further reducing the incidence probability of the plant fever and heart disease.

Preferably, the control module 130 includes at least a humidifying operation for the humidity of the plant growing environment in the planting device 100. Preferably, the embodiment of the humidifying operation is such that, in case that the humidity of the growing environment of the plants in the planting device 100 is lower than the proper humidity for growth thereof, the control module 130 generates a humidifying command transmitted to the spraying module 110, and in response to receipt of the humidifying command, the spraying module 110 sprays the atomized solution to the growing environment of the plants in the planting device 100 to increase the humidity of the growing environment of the plants.

Preferably, the control module 130 also includes a dehumidifying operation for the humidity of the plant growing environment in the planting device 100. Preferably, the dehumidifying operation is performed such that, in case that the humidity of the growing environment of the plant in the planting device 100 is higher than the proper humidity for growth thereof, the control module 110 generates a dehumidifying command transmitted to the air circulation module 120, and in response to receipt of the humidifying command, the air circulation module 120 increases the flow rate of air near the first and

second ventilation openings

121 and 122 of the growing environment of the plant such that the flow rate of the first air near the growing environment of the plant is accelerated, thereby taking moisture of the growing environment of the plant out of the planting device 100 to reduce the humidity of the growing environment of the plant.

Preferably, the airflow circulation module 120 forms a second airflow in the inner cavity of the casing 101 opposite to the spraying direction of the atomized solution of the spraying module 110 through the third air openings 123, and the second airflow and the first airflow can leave the inner cavity of the casing 101 from the second air openings 122 to remove moisture in the planting device 100, so as to reduce the humidity of the plant growing environment.

Preferably, the third air vents 123 disposed at the bottom of the planting device 100 can generate a second air flow along the direction from the root system to the canopy of the plant, and because the second air flow has less obstruction to the air flow by the plant, the second air flow can better take away the air with high humidity and high temperature on the surface of the plant leaf compared with the mode of taking away the air with high humidity and high temperature on the surface of the plant leaf by the first air flow, thereby reducing the incidence rate of the plant fever and heart disease.

Preferably, at least a first infusion tube 111 for transporting the pesticide and the disinsection liquid and a second infusion tube 112 for transporting the aqueous solution for increasing the humidity of the plant growing environment are connected to the spray module 110.

Preferably, the spray module 110 is provided with several spray openings 113, each spray opening 113 corresponding to a different plant growing area. Preferably, the spray opening 113 increases the humidity of the plant growing environment in the form of spray. Preferably, the spray module 110 can adjust the size of atomized particles ejected from the spray outlet 113.

Preferably, the air circulation module 120 is provided with a first vent 121, a third vent 123, and a second vent 122. Preferably, the first vent 121 generates a first air flow perpendicular to the direction of solution spraying from the spray port 113. The third air vent 123 generates a second air flow opposite to the spraying direction of the solution from the spraying port 113. The first air stream and the second air stream leave the plant growing environment from the second air vent 122.

Preferably, the third ventilation opening 123 is provided near the plant growing area. In the case that the spray opening 113 sprays the solution, the second air flow generated from the third air vent 123 can lengthen the dead time of the atomized solution, thereby increasing the humidity of the planting environment, particularly the air humidity.

Preferably, when it is desired to increase the air humidity, the spray module 110 sprays the solution through the spray ports 113. Preferably, at this time, the size of the atomized particles of the water droplets sprayed from the spray outlet 113 by the spray module 110 is between 5 micrometers and 0.5 millimeters. Preferably, the air circulation module 120 generates a second air flow opposite to the solution spraying direction through the third air vent 123. Preferably, the second air flow acts on the water droplet atomized particles sprayed out from the spraying opening 113 to provide an ascending force opposite to the gravity acting direction for the water droplet atomized particles, so as to delay the descent of the water droplet atomized particles and further prolong the dead time of the atomized solution. Preferably, the lifting force of the second air flow acting on the bead-atomized particles increases with the shortening of the distance between the bead-atomized particles and the third air port 123, even when the distance between the bead-atomized particles and the third air port 123 is shortened to a certain value, the lifting force of the second air flow acting on the bead-atomized particles is greater than the gravity force on the bead-atomized particles, so that the bead-atomized particles cannot fall to the substrate 101.

Preferably, the water droplet atomized particles sprayed from the spraying opening 113 cannot descend onto the substrate 101 in a short time, and the water droplet atomized particles sprayed from the spraying opening 113 continuously increase a large amount of water droplet atomized particles in the air, so that the humidity of the plant growing environment is increased.

Preferably, the planting device 100 is configured with at least two humidification modes according to the planting environments when planting the plants 200 in different forms. Preferably, the planting device 100 configures different humidification modes by setting atomized particle parameters, wind power parameters, start-stop periods and the like, so as to meet the requirements of the planting environment humidity when planting plants 200 in different forms.

Preferably, when planting the wheat at the time of the plant 200, the planting device 100 is configured with two humidification modes, respectively: a first humidification mode that meets the humidity requirements of the planting environment when wheat is primarily present in seed form; and a second humidification mode meeting the humidity requirement of the planting environment when the wheat exists mainly in the form of seedlings.

Preferably, the planting device 100 determines the humidification mode by determining the wheat growth morphology through processing the images acquired by the camera 131.

Preferably, when the planting device 100 is in the first humidification mode, the diameter of the water droplets atomized particles sprayed from the spraying port 113 by the spraying module 110 is between 0.3 and 0.5 mm, and the third air outlet 123 in the air circulation module 120 stops air outlet. Preferably, when the wheat is in a sowing stage and a seedling stage, the wheat exists mainly in the form of seeds in the culture medium, and when the humidity of the planting environment is increased, the humidity of the culture medium needs to be increased. Preferably, in the first humidification mode, the spray module 110 sprays as large as possible water droplet atomized particles from the spray port 113 so that the weight of individual water droplet atomized particles is as large as possible, and since the third air outlet 123 in the air circulation module 120 stops the air-out, the water droplet atomized particles are subjected to only gravity and air resistance in the vertical direction, and thus, the water droplet atomized particles can rapidly drop down to the culture medium to increase the humidity thereof, thereby increasing the planting environment humidity of plant seeds.

Preferably, when the planting device 100 is in the first humidification mode, the diameter of the water droplets atomized particles sprayed from the spraying port 113 by the spraying module 110 is between 0.4 and 0.5 mm, and the third air outlet 123 in the air circulation module 120 stops air outlet. Preferably, when wheat exists mainly in the form of seeds, the main body of the wheat is located in the culture medium, and when the humidity of the planting environment is increased, the humidity of the culture medium needs to be increased. Preferably, in the first humidification mode, the spray module 110 sprays as large as possible water droplet atomized particles from the spray port 113 so that the weight of individual water droplet atomized particles is as large as possible, and since the third air outlet 123 in the air circulation module 120 stops the air-out, the water droplet atomized particles are subjected to only gravity and air resistance in the vertical direction, and thus, the water droplet atomized particles can rapidly drop down to the culture medium to increase the humidity thereof, thereby increasing the planting environment humidity of plant seeds.

Preferably, when the planting device 100 is in the second humidification mode, the diameter of the water droplets atomized particles sprayed from the spraying port 113 by the spraying module 110 is between 0.2 and 0.3 mm, and the third air outlet 123 in the air circulation module 120 is air-out at the first air speed.

Preferably, the change in force of the water droplet atomized particles is reflected in their motion as: in the vertical direction, the water drop atomized particles firstly do acceleration movement with reduced acceleration downwards until reaching the maximum speed V ₁ Then the deceleration movement with increased acceleration is performed downwards until the speed is reduced to zero, and then the water drop atomized particles are performed upwards with the acceleration movement with reduced acceleration until the maximum speed V is reached ₂ Then the water drop atomized particles firstly do acceleration movement with reduced acceleration downwards until reaching maximum speed V ₃ Then the deceleration movement with increased acceleration is performed downwards until the speed is reduced to zero … …, and the maximum speed V is generated due to air resistance _i <V _i+1 Where i=1, 2,3,4, … …

Preferably, when the water droplet atomized particles reciprocate in the vertical direction under the action of the second air flow, the movement area is mainly concentrated near the wheat blades, so that the air humidity of the area near the wheat blades is increased. Preferably, in the second humidification mode, the second air flow continuously generated by the third air vent 123 retards the water droplet atomizing particles in the vicinity of the wheat blades, thereby increasing the humidity of the planting environment when present in the form of seedlings.

Preferably, as the wheat seedling height increases, the third air vent 123 in the airflow circulation module 120 vents at a second wind speed that is faster than the first wind speed. Preferably, the second air flow generated by the third air vent 123 exerts a larger force on the water droplet atomizing particles as the air speed increases, so that the movement range of the water droplet atomizing particles in the vertical direction is narrower, and the height of the water droplet atomizing particles in suspension is increased along with the height of wheat seedlings, thereby ensuring the air humidity of the wheat planting environment.

Preferably, when the humidity adjusting unit 130 increases the air humidity, the first ventilation opening 121 of the air circulation module 120 does not wind or is at a low wind speed, and the third ventilation opening 123 intermittently generates the second air flow to prolong the air stagnation time of the atomized solution without taking away the moisture in the planting device 100, thereby promoting the increase of the planting environment humidity.

Preferably, the plant 200 in the planting device 100 may be wheat. Preferably, the growth cycle of wheat can be divided into: soaking seeds, sowing, raising seedlings and growing. The seed soaking stage is to soak the wheat seeds in water at 20-50 deg.c for 8-24 hr. The sowing stage is to sow the seeds which are water-absorbed and exposed to the white into a 72-hole cave dish and place the cave dish in the dark to wait for emergence of seedlings. The seedling stage is to place the plug tray in the illumination environment for cultivation after the wheat seedlings are grown until the wheat plant height exceeds 5-15cm. The growth stage is to move the wheat from the tray to the planting basket for culturing.

Preferably, the growth stage of wheat can be further divided into a vegetative growth stage and a reproductive growth stage by taking wheat heading as a sign. Preferably, the relative humidity of air is controlled between 60% and 75% during the vegetative growth stage when wheat is not heading. Preferably, the relative humidity of air is controlled to be 60% -70% in the reproductive growth stage after wheat heading.

Preferably, when the wheat is located in the tray or planting basket, the tray or planting basket containing the wheat is placed at the bottom of the planting device 100 and the humidity in the wheat planting environment is controlled by the planting device 100.

Preferably, when the wheat is in the sowing stage and the seedling stage, the wheat is mainly present in the culture medium in the form of seeds, and at this time, the ambient humidity affecting the growth of the wheat means the humidity of the medium. Preferably, when the wheat is in the vegetative and reproductive growth stages, the wheat is predominantly present in the form of seedlings, the majority of which are located in the air, and at this point the ambient humidity affecting the growth of the wheat is the humidity of the air.

Preferably, the humidity sensor 132 may be provided at the bottom of the planting device 100 to detect the humidity of the air or may be provided in a tray or a planting basket to detect the humidity of the culture medium.

Preferably, the camera 131 captures an image in the bottom region of the planting device 100 and transmits the captured image to the control module 130. The control module 130 processes the image to confirm the growth stage in which the wheat is growing and to determine the humidity suitable for its growth. The control module 130 acquires the actual humidity of the environment in which the wheat is located through the humidity sensor 132, and the control module 130 determines whether to adjust the humidity in the environment in which the plant is located by comparing the actual humidity of the environment in which the wheat is located with the humidity suitable for its growth.

Preferably, the control module 130 determines that the wheat is currently at a certain growth stage in the fertility cycle by processing the image. Preferably, the wheat is in the sowing stage when no wheat leaves are present in the image acquired by camera 131. When the leaves of wheat can be observed in the image collected by the camera 131 but the plant height of wheat is not more than 5cm, the wheat is in a seedling stage. When the wheat plant height in the image acquired by the camera 131 exceeds 5cm but the wheat does not heading, the wheat is in a vegetative growth stage. When wheat ears are observed in the image acquired by the camera 131, the wheat is in a reproductive growth stage.

Preferably, the control module 130 detects the humidity of the culture medium through the humidity sensor 132 provided in the tray or the planting basket when the wheat is in the sowing stage and the seedling stage. Preferably, when the humidity of the culture medium is lower than the humidity suitable for its growth, the control module 130 generates a humidification command and sends it to the spraying module 110. The spray module 110 sprays a solution to the bottom of the planting device 100 through the spray ports 113 to increase the humidity of the substrate until the humidity detected by the humidity sensor 132 provided in the tray or the planting basket is a humidity suitable for the growth of wheat. Preferably, when the humidity adjusting unit 130 increases the humidity of the substrate, the air circulation module 120 is in a standby state, and the first ventilation opening 121, the second ventilation opening 122 and the third ventilation opening 123 may not be ventilated or the air speed is low, so that the solution sprayed from the spray opening 113 to the bottom of the planting device 100 may rapidly drop into the tray or the planting basket, thereby increasing the humidity of the substrate. Preferably, when the humidity of the culture substrate is higher than the humidity suitable for its growth, the control module 130 generates a dehumidification command and sends it to the air circulation module 120. The air flow rate of the air circulation module 120 passing through the first ventilation opening 121, the second ventilation opening 122 and the third ventilation opening 123 accelerates the first air flow and the second air flow, and takes away moisture in the planting device 100, thereby promoting the volatilization of the moisture in the substrate and further reducing the humidity of the substrate.

Preferably, the control module 130 detects the air humidity through the humidity sensor 132 provided at the bottom of the planting device 100 when the wheat is in the vegetative and reproductive growth phases. Preferably, when the air humidity is lower than the humidity suitable for wheat growth, the control module 130 generates a humidification command and sends it to the spraying module 110. The spraying module 110 sprays the solution through the spraying port 113, and the air flow circulation module 120 generates a second air flow opposite to the spraying direction of the solution through the third air vent 123 to extend the dead time of the atomized solution, thereby increasing the humidity of the planting environment. Preferably, when the planting device 100 increases the air humidity, the first ventilation opening 121 of the air circulation module 120 does not exhaust air, and the third ventilation opening 123 intermittently generates the second air flow to prolong the air stagnation time of the atomized solution without taking away the moisture in the planting device 100, so as to promote the increase of the planting environment humidity. Preferably, when the air humidity is higher than the humidity suitable for wheat growth, the control module 130 generates a dehumidification command and sends it to the air circulation module 120. The air circulation module 120 increases the air flow rates of the first air flow and the second air flow by increasing the air flow rates of the first air vent 121, the second air vent 122 and the third air vent 123, so that the water in the air of the planting device 100 is taken away, and the air humidity is reduced.

Preferably, the diameter of the atomized particles sprayed from the spray ports 113 by the spray module 110 when the humidity of the substrate is increased is larger than the diameter of the atomized particles sprayed from the spray ports 113 by the humidity adjustment unit 130 when the humidity of the air is increased. In other words, the spray module 110 is in the first spray mode where the atomized particles are larger when the humidity of the substrate is increased. The spray module 110 is in a second spray mode with smaller atomized particles when the air humidity is increased.

Preferably, the spray module 110 sprays larger water droplet atomized particles from the spray outlet 113 when increasing the humidity of the substrate, so that the water droplet atomized particles can fall into the tray or the planting basket faster under the action of gravity, thereby increasing the humidity of the substrate.

Preferably, the spraying module 110 sprays smaller water droplets from the spraying port 113 to atomize the particles when increasing the air humidity, so that the air resistance of the atomized particles can effectively prolong the dead time of the atomized particles, thereby rapidly increasing the air humidity.

Preferably, the planting device 100 cultures wheat using a mist culture. Preferably, the spraying module 110 sprays a solution including at least an aqueous solution for increasing the humidity of the plant growing environment and an insecticide for killing insects. Preferably, the spray module 110 may be connected to both a first fluid line 111 for transporting the pesticide and the second fluid line 112 for transporting the aqueous solution that increases the humidity of the plant growing environment.

Preferably, the spray module 110 may perform different functions by selecting different infusion lines to change the type of solution being sprayed. Preferably, in case that it is necessary to humidify the plant growing environment, the spraying module 110 may increase the humidity of the growing environment by spraying the aqueous solution. Preferably, in the event that pest control is desired on the plants, spray module 110 may fertilize the plants by spraying the pesticide.

Preferably, the conduit of the third vent 123 is connected to a carbon dioxide bottle and its release system 140. In the case where the third air vent 123 generates the second air flow to entrain the air of high humidity and high temperature on the surface of the plant leaf, the carbon dioxide bottle and its release system 140 release carbon dioxide and deliver the carbon dioxide to the vicinity of the plant leaf through the third air vent 123.

The ventilation system of the existing plant factory often causes the flow velocity to be reduced at the position close to the plants due to the blocking of the plants, particularly under the condition of dense planting of the plants, the position below the canopy of the plants often causes insufficient air flow among the leaves due to the mutual shielding of the plants, so that the air with high humidity and high temperature on the surfaces of the leaves is detained, the transpiration of the plants is reduced to cause the heart burn, and carbon dioxide near the leaves is continuously consumed due to photosynthesis of the plants. Because the air flow of the part below the plant canopy is insufficient, carbon dioxide near the leaves cannot be supplemented, so that the photosynthesis efficiency of the plant is reduced, and the plant growth is affected.

Preferably, the present embodiment utilizes the second air flow to transport carbon dioxide to the vicinity of plant leaves by connecting a carbon dioxide bottle and its release system 140 to the pipe of the third air vent 123, so as to improve photosynthesis efficiency of plants and promote plant growth.

Preferably, the embodiment can supplement carbon dioxide to the part below the wheat canopy. Preferably, upon supplementing the site below the wheat canopy with carbon dioxide, the control module 130 determines the height of the wheat canopy based on the image captured by the camera 131 and sends the height data of the wheat to the airflow circulation module 120. In response to receipt of the height data of the wheat canopy, the airflow circulation module 120 adjusts the mode of operation of each vent such that the airflow within the planting device 100 limits supplemental carbon dioxide gas to a location below the wheat canopy. Preferably, the adjustment of the air circulation module 120 to each vent operation mode includes at least one or more of wind speed, wind direction, temperature, etc.

Preferably, the first vent 121 and the third vent 123 are configured as air outlets, and the second vent 122 is configured as an air inlet. The air flow enters the planting device 100 from the first vent 121 and the third vent 123 and exits the interior of the planting device 100 through the second vent 122. Preferably, the first ventilation opening 121 and the second ventilation opening 122 form a first air flow flowing laterally inside the planting device 100.

Preferably, when supplementing carbon dioxide to the part below the wheat canopy, the air outlet speeds of the first air vent 121 and the second air vent 122 on the side wall of the planting device 100 higher than the height of the wheat canopy are adjusted to be the first air speed; the air outlet speeds of the first air vent 121 and the second air vent 122 on the side wall of the planting device 100 lower than the height of the wheat canopy are adjusted to be a second air speed greater than the first air speed. Preferably, the air outlet speeds of the first ventilation opening 121 and the second ventilation opening 122 arranged on the side wall of the planting device 100 are adjusted according to the height of the wheat canopy, so that air pressure differences occur in the transverse air flows above and below the wheat canopy. Preferably, the first gas flow rate above the wheat canopy is greater than the first gas flow rate below the wheat canopy, in other words the gas pressure above the wheat canopy is higher than the gas pressure below the wheat canopy. Preferably, in this embodiment, by forming a pressure difference between the upper and lower parts of the wheat canopy, carbon dioxide released through the third ventilation opening 123 is difficult to diffuse to a high-pressure area (an area above the wheat canopy), so that the released carbon dioxide is limited to a position below the wheat canopy, so as to supplement carbon dioxide near the wheat leaves, increase photosynthesis efficiency of plants, and promote plant growth.
