The processing unit 540 can also transmit the growth status information of the corresponding animals and plants collected by the monitoring probe unit 420 to the central control unit 520 through the communication unit 530, so that the central control unit 520 can compare the real-time growth status of different animals and plants with the standard growth status in the database, when the animals and plants in any growth area are abnormal in growth, the central control unit 520 can send a control signal to the communication unit 530, so that the processing unit 540 can regulate and control the housing part 100, the light source part 200 and/or the power part 300 according to the control signal, so as to realize real-time regulation of environmental parameters at least including illumination in the growth area, and thus ensure that different animals and plants can be cultivated based on an appropriate growth speed. Alternatively, the processing unit 540 may adjust the light source parameters by changing the illumination intensity, illumination angle, illumination coverage and the like of the light source 200 based on the control signal, or indirectly adjust the position of the light source 200 by changing the rotation speed of the different motors 321 of the driving unit 320, thereby implementing the auxiliary adjustment of the light source parameters of the light source 200.

According to a preferred embodiment, based on the growth characteristics of different animals and plants, the illumination parameters required at different stages in the growth process are different, so that a plurality of growth areas suitable for the growth of different animals and plants can be divided by reasonably dividing the whole culture area, and the light source part 200 can complete the movement between the growth areas and the movement such as mooring, lifting and the like in any growth section along with the movement of the driving unit 320 along the preset path. Preferably, the whole cultivation area is at least divided into growth areas for cultivating plants, namely, a mixed animal and plant partition mode or a whole plant partition mode is adopted, so that oxygen generated when the plants carry out photosynthesis can be supplied to animals and plants in other growth areas to complete respiration.

For example, a plurality of growth areas formed by dividing the whole cultivation area are illuminated and monitored by using the agricultural lighting device, wherein a first growth area 1 can be set as a growth area of a first plant, a second growth area 2 adjacent to the first growth area 1 can be set as a growth area of a second animal/plant, and there is no conflict between light receiving time of the second animal/plant and light receiving time of the first plant, so that when the power unit 300 drives the light source unit 200 to move to a corresponding position at a height corresponding to the first growth area 1, the first plant located in the first growth area 1 can receive light and perform photosynthesis and respiration simultaneously, and as the photosynthesis rate is higher than respiration and a high-density cultivation mode adopted for improving land utilization rate, the oxygen concentration and the light concentration gradually increase in the first growth area 1 along with illumination, and the carbon dioxide concentration gradually decreases. When the concentration of carbon dioxide is too low, the photosynthesis rate of the first plant is seriously influenced, so that the photosynthesis efficiency cannot be effectively improved even if the illumination intensity is increased, and the energy is wasted while the culture yield and quality are seriously influenced. Further, the sensing unit 510, such as an oxygen sensor, a carbon dioxide sensor, a temperature sensor, a humidity sensor, and/or a light intensity sensor, disposed in the first growth area 1 can obtain the real-time photosynthesis rate of the first plant through the central control unit 520 after monitoring the real-time environment of the first growth area 1, judge the real-time photosynthesis rate based on the photosynthesis rate curve of the first plant, and determine an appropriate adjustment mode by combining with the real-time environment parameters. The central control unit 520 may set a corresponding first threshold and a corresponding second threshold for each monitoring parameter, where when a value obtained by any monitoring parameter is between the corresponding first threshold and the corresponding second threshold, it indicates that the value of the monitoring parameter is normal; when the value obtained by any monitoring parameter is lower than the corresponding first threshold value or higher than the corresponding second threshold value, the value of the monitoring parameter is over-low or over-high, and timely adjustment is needed to ensure the normal growth of the first plant. By comparing each monitored parameter with the corresponding threshold, the cause of the abnormal photosynthesis rate can be determined, and the light source unit 200 can be adjusted when the cause is caused by the illumination factor.

Further, if the cause of the abnormal photosynthesis rate is the abnormal concentration of oxygen and/or carbon dioxide, the abnormal photosynthesis rate can be at least partially adjusted by the driving unit 320 of the power unit 300. For example, when the carbon dioxide concentration in the first growth area 1 is lower than the corresponding first threshold value due to the progress of photosynthesis, in order to ensure the photosynthesis rate of the first plant, the lower wash air that does not damage the first plant can be generated by the propeller 322 in the direction toward the first growth area 1 by lowering the hovering height of the driving unit 320 or by increasing the rotation speed of the propeller 322, and the air containing oxygen at a high concentration in the first growth area 1 is pushed by the lower wash air to spread around to the second growth area 2, so that the oxygen consumed by respiration in the second growth area 2 that is not receiving light can be replenished, and at the same time, the air containing carbon dioxide at a high concentration in the periphery to the second growth area 2 can be drawn in by the rotation of the propeller 322 on the side away from the first growth area 1, and the air containing carbon dioxide at a high concentration in the periphery to the second growth area 2 can be input to the first growth area 1 again by the lower wash air through the propeller 322, so that the carbon dioxide replenishment of the carbon dioxide at the first growth area 1 is completed, and the reutilization of oxygen and carbon dioxide is realized. After the illumination process of the first growth area 1 is finished, the power portion 300 may drive the light source portion 200 to move to a corresponding position of the second growth area 2 at a corresponding height, so as to realize illumination of the second growth area 2. The agricultural lighting apparatus may have different adjustment modes according to the type of the second animal/plant cultivated in the second growth area 2, for example, when the second growth area 2 is cultivated as a second animal, since the second animal still only breathes under the lighting conditions, the air flow exchange may be performed in the second half of the lighting cycle of the second growth area 2 to input the air containing high concentration of carbon dioxide in the second growth area 2 into the first growth area 1, so as to prepare for the next lighting cycle of the first growth area 1; when the second growing area 2 is a second plant, since the second growing area 2 and the first growing area 1 are both used for plant cultivation, the agricultural lighting device can be adjusted in the second growing area 2 in a manner consistent with the manner in which the agricultural lighting device is adjusted in the first growing area 1. Preferably, each growth area can be also independently provided with an oxygen and/or carbon dioxide charging and discharging assembly so as to achieve more flexible and precise adjustment, and a purification assembly can be further arranged on a gas escape channel between the growth areas so as to avoid cross transfer of pollutants. Preferably, the central control unit 520 is capable of performing comprehensive adjustment on at least the housing portion 100, the light source portion 200 and/or the power portion 300 based on each monitored parameter of the growing area where the agricultural lighting device is located and other adjacent or related growing areas, so that each type of environmental parameters at least including the illumination parameter and the air ratio parameter in each growing area is within a range suitable for growth of the corresponding animal and plant. Optionally, the housing portion 100 may further be connected with a fixing rope parallel to the tethered cable, and the other end of the fixing rope may be connected with a fixing rope retracting mechanism fixed near the main power supply, so that the motor 321 may maintain the housing portion 100 in a relatively fixed position based on the pulling force of the fixing rope when the rotating speed is increased to obtain a stronger airflow under the propeller 322, thereby ensuring that the illumination parameters of the illumination portion are substantially kept unchanged while obtaining the stronger downwash airflow.

Further, the driving unit 320 may be provided with propellers 322 of different structural sizes so that the downwash airflow generated by the propellers 322 has different flow velocity profiles at least in the space flowing to the corresponding growth area. The downwash of any one of the propellers 322 can be distributed symmetrically around the rotation axis of the corresponding propeller 322, and no slip flow is generated in the space projected to the growth area at the rotation center, so that the downwash can be contracted and expanded. When the propellers 322 act together, the interval between the propellers 322 is large, so that the slipstream of each propeller 322 facing one side of the growing area is in a relatively independent state, the slipstream flow rate in a part of space right opposite to the position of the propeller 322 is large and stable, and meanwhile, the flow rate of at least a part of space projected to the growing area by the part of the shell part 100 which is not in the radiation range of the propeller 322 is small, even in a zero-wind-speed area, so that the downwash airflow can avoid the body of the corresponding animal and plant in the growing area, and disturb the gas around the animal and plant, thereby realizing the gas circulation with other growing areas and avoiding the damage caused by the direct contact of the animal and plant with a large amount of downwash fluid. Furthermore, the lower washing airflow generated by the rotation of the propeller 322 can also blow the airflow on the surfaces of the animals and plants in the growth area under the condition of not damaging the bodies of the animals and plants, so that pollutants such as dust and/or suspended particles possibly covering the surfaces of the blades, eggshells and the like can be cleaned through the blowing of the airflow, and the light receiving process of the animals and plants is prevented from being influenced by the covering of the pollutants.

Furthermore, some fungi can form mycorrhiza in a symbiotic manner with plant roots so as to enlarge the absorption surface of the root system through the mycorrhiza and increase the absorption capacity of elements outside the absorption range of the primitive root hair, wherein the mycorrhiza fungi mycelium can obtain organic substances from host plants as nutrients of the host plants and can also supply external nutrients and water to the plants. Since the mycorrhizal fungi are mostly aerobic fungi, when the agricultural lighting device is used for adjusting environmental factors including illumination, air and the like, the oxygen consumption of part of the aerobic fungi beneficial to plant growth, such as the mycorrhizal fungi, needs to be considered, wherein when the central control unit 520 analyzes and processes the oxygen content in the growth area collected by the oxygen sensor, the control signal can be corrected according to the oxygen consumption of the aerobic fungi, such as the mycorrhizal fungi, so as to ensure that the oxygen content in the growth area can at least ensure the oxygen consumption of the respiration of the plants and the aerobic fungi.
