With the increasing emphasis on the protection and restoration of mangrove ecosystems, the demand for mangrove planting is increasing day by day.

[0003] Traditional mangrove seedling raising and planting methods have some limitations. During the seedling raising process, it is difficult to accurately carry out targeted irrigation and environmental management according to the species and growth status of mangroves. For example, different mangrove species have different requirements for growth conditions such as salinity and moisture, and the traditional method cannot monitor in real time and adjust flexibly. At the same time, in terms of irrigation methods, there is a lack of effective means to automatically switch according to the growth stage of mangroves, which may lead to water resource waste or inability to meet the growth needs of mangroves. In addition, the adjustment of temperature, humidity, air quality, etc. of the planting environment is not accurate and intelligent enough, affecting the success rate and growth quality of mangrove seedling raising. Therefore, an ecological cultivation and seedling raising system and method that can comprehensively and accurately manage mangrove planting are needed to improve the efficiency and quality of mangrove seedling raising and promote the restoration and development of mangrove ecosystems.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figure 1 and Figure 2 shown, the ecological cultivation and seedling raising system for mangrove planting provided in this embodiment includes:

[0034] A mangrove planting management system for comprehensively managing the mangrove seedlings in the mangrove planting ecological cabin;

[0035] The mangrove planting management system includes an imaging unit, a planting analysis module, and a planting control module. The imaging unit is used to obtain pictures of mangrove seedlings. The planting analysis module identifies the image features of the pictures of mangrove seedlings to obtain the mangrove species and the growth state of the mangroves. The planting control module generates irrigation and environment adjustment instructions based on the mangrove species and the growth state of the mangroves.

[0036] Specifically, when implemented, the imaging unit obtains pictures of mangrove seedlings through devices such as cameras, providing basic data for subsequent analysis. Specifically, a high-definition camera is installed at a suitable position in the mangrove planting ecological cabin to regularly capture images of the seedling raising area.

[0037] The planting analysis module uses image recognition technology and related algorithms to process the obtained mangrove seedling pictures, and identifies the mangrove species (such as Kandelia obovata, Avicennia marina, etc.) and the growth status of mangroves (including seedling height, leaf color, stem thickness, etc.). For example, the convolutional neural network model in the deep learning algorithm is used to pre-train a large number of image data of different mangrove species at different growth stages, so as to accurately judge the species and growth status of the current mangrove seedlings.

[0038] The planting control module generates corresponding irrigation and environmental regulation instructions according to the mangrove species and growth status obtained by the planting analysis module. Specifically, if a certain mangrove variety is identified in the seedling stage and the growth status is weak, instructions to increase the spray irrigation frequency and appropriately increase the environmental temperature and humidity may be generated.

[0039] The mangrove hydroponic seedling device includes an irrigation control unit and an irrigation liquid circulation unit. The irrigation control unit is electrically connected to the mangrove planting management system. The irrigation control unit receives the irrigation regulation instructions and controls the flow of the irrigation liquid in the irrigation circulation unit to achieve spray irrigation or tidal irrigation;

[0040] The mangrove hydroponic seedling device further includes a planting tank, which is arranged horizontally for planting mangrove seedlings; the irrigation liquid circulation unit includes a water pumping device, a water storage device and a circulation pipeline; the circulation pipeline includes a water inlet pipeline connected to the liquid inlet end of the water pumping device and a spray irrigation pipeline and a tidal irrigation pipeline respectively connected to the liquid outlet end of the water pumping device; the water storage device includes a water supply storage tank, and the water supply storage tank is communicated with the water inlet pipeline;

[0041] An electromagnetic valve is arranged on the circulation pipeline, and the electromagnetic valve is electrically connected to the irrigation control unit; the water pumping device is electrically connected to the irrigation control unit; the spray irrigation pipeline is arranged at the top of the planting tank, and the tidal irrigation pipeline is arranged at the placement position of the mangrove planting tray.

[0042] During specific implementation, the planting tank is placed horizontally in the mangrove planting ecological cabin for placing mangrove seedlings and growth substrates. Its material can be selected from corrosion-resistant and non-toxic plastics or fiberglass, etc. The size is designed according to the actual seedling raising scale to ensure that the mangrove seedlings have enough growth space.

[0043] In the irrigation liquid circulation unit, a water pump with an appropriate power is used as the water pumping device, which can provide stable water flow power. The capacity of the water supply and storage tank in the water storage device is determined according to the seedling raising cycle and water demand to ensure an adequate water source supply. The inlet pipeline, spray irrigation pipeline, and tidal irrigation pipeline of the circulation pipeline are made of corrosion-resistant plastic pipes, and the pipe diameter is designed according to the water flow demand. The solenoid valve on the circulation pipeline is connected to the irrigation control unit, and its opening and closing are controlled by an electrical signal to achieve the switching of different irrigation methods. For example, when spray irrigation is required, the irrigation control unit controls the corresponding solenoid valve to open, so that clear water enters the spray irrigation pipeline from the water supply and storage tank through the water pumping device and is sprayed at the top of the planting tank; when tidal irrigation is required, another solenoid valve is controlled to open, so that the nutrient solution enters the tidal irrigation pipeline from the storage tank through the water pumping device to simulate the natural tidal phenomenon for irrigation.

[0044] The environmental regulation device receives the environmental regulation instruction to regulate the environmental state of the mangrove planting ecological cabin, and the environmental state includes temperature, humidity, and air quality.

[0045] The environmental regulation device includes at least one of a temperature regulation device, a humidity regulation device, and an air quality regulation device; the environmental regulation device further includes a lighting device, and the lighting device includes an artificial light source and a light source control unit, and the light source control unit receives the environmental regulation instruction to achieve dimming control of the artificial light source.

[0046] In specific implementation, the temperature regulation device can adopt an air conditioning system or heating and cooling equipment to control the temperature in the mangrove planting ecological cabin within an appropriate range, such as 20°C - 30°C according to the environmental regulation instruction. The humidity regulation device can be a combination of a humidifier and a dehumidifier to maintain the relative humidity at 70% - 90%. The air quality regulation device can include an air purifier and ventilation equipment to ensure fresh air and sufficient oxygen in the cabin. The artificial light source of the lighting device can select LED plant growth lights, and the light source control unit adjusts the light intensity, light time, etc. according to the growth needs of mangroves. For example, stronger light is provided during the seedling stage of mangroves to promote photosynthesis, and the light intensity is appropriately reduced or the light source is turned off at night.

[0047] The salinity regulation device is used to regulate and maintain the water salinity in the mangrove planting ecological cabin to meet the growth needs of different species of mangroves.

[0048] The salinity regulation device includes a salinity detection unit and a salinity regulation execution unit. The salinity detection unit is used to detect the water salinity in the mangrove planting ecological cabin, and the salinity regulation execution unit receives the salinity regulation instruction issued by the mangrove planting management system to regulate the water salinity.

[0049] During specific implementation, the salinity detection unit uses a high-precision salinity sensor to monitor the water salinity in the mangrove planting ecological cabin in real time. The salinity adjustment execution unit adjusts the water salinity by adding fresh water or salt solution according to the salinity adjustment instruction issued by the mangrove planting management system. For example, when it is detected that the water salinity is lower than the suitable growth salinity range of a certain mangrove variety, the salinity adjustment execution unit starts the operation of adding an appropriate amount of salt solution; when the salinity is too high, fresh water is added for dilution.

[0050] An ecological cultivation and seedling raising method for mangrove planting, including:

[0051] Obtain the mangrove seedling raising picture, and obtain the mangrove species and the mangrove growth state characteristics based on the machine vision algorithm;

[0052] Obtain the mangrove seedling raising maturity level according to the mangrove species and the mangrove growth state characteristics, and the setting of the maturity level corresponds to the growth characteristics of different stages of the mangrove cotyledons, and the preset level is set as the maturity level corresponding to the cotyledon unfolding state of the mangrove;

[0053] Generate irrigation and environment adjustment instructions according to the maturity level: when the maturity does not meet the preset level, generate a spray irrigation control instruction; when the maturity meets the preset level, generate a tidal irrigation control instruction; generate an environment adjustment instruction according to the mangrove growth environment requirements;

[0054] Send the irrigation control instruction to the mangrove hydroponic seedling device, and send the environment adjustment instruction to the environment adjustment device;

[0055] Monitor and adjust the water salinity in the mangrove planting ecological cabin to meet the growth requirements of different mangrove species.

[0056] It also includes: recycling the irrigation liquid, and recycling the recycled irrigation liquid for the automatic preparation of nutrient solution and for the tidal irrigation in the later stage of mangrove seedling raising.

[0057] After receiving the spray irrigation control instruction, the irrigation control unit controls the circulating flow of clear water in the irrigation circulation unit to the spray pipeline to complete the spray irrigation of the mangrove hydroponic seedling device; after receiving the tidal irrigation control instruction, the irrigation control unit controls the circulating flow of nutrient solution in the irrigation circulation unit to the tidal irrigation pipeline to complete the tidal irrigation of the mangrove hydroponic seedling device.

[0058] During specific implementation, the imaging unit in the mangrove planting management system is used to obtain the mangrove seedling raising picture at regular time intervals (such as every day or every two days), and then it is processed by the planting analysis module based on the machine vision algorithm. The captured image is input into a pre-trained model, and the model outputs the mangrove species and the mangrove growth state characteristics, such as the number of leaves, leaf area, stem height change of the mangrove seedlings, etc.

[0059] Determine the maturity level of mangrove seedlings

[0060] Based on the obtained mangrove species and growth status characteristics, the maturity level of the current mangrove seedlings is determined by referring to the preset maturity level standards. For example, if the cotyledons of the mangrove have just started to grow, according to the corresponding relationship between the maturity level and the cotyledon growth characteristics, it is judged that it is at a relatively low maturity level; if the cotyledons are fully unfolded and reach the state corresponding to the preset level, it is determined to meet the preset level.

[0061] Generate irrigation and environmental regulation instructions

[0062] When the maturity level does not meet the preset level, the planting control module generates spray irrigation control instructions, such as setting the number of spray times per day to 3 - 5 times and the spray time per time to 10 - 15 minutes, etc.; when the maturity level meets the preset level, it generates tidal irrigation control instructions, such as performing 2 - 3 tidal irrigations per day and the tidal ebb and flow time per time to 2 - 3 hours, etc. At the same time, according to the mangrove growth environment requirements (such as the requirements of different mangrove species for temperature, humidity, light, etc.), environmental regulation instructions are generated. For example, for some mangrove varieties that are heat - resistant, the upper limit of the environmental temperature can be appropriately increased in summer, and for shade - loving mangrove varieties, the light intensity can be appropriately reduced when the light is too strong.

[0063] Execute irrigation and environmental regulation operations

[0064] After the irrigation control unit receives the spray irrigation control instructions, it controls the circulating flow of fresh water in the irrigation circulation unit to the spray pipeline to complete the spray irrigation of the mangrove hydroponic seedling device; after receiving the tidal irrigation control instructions, it controls the circulating flow of nutrient solution in the irrigation circulation unit to the tidal irrigation pipeline to complete the tidal irrigation. The environmental regulation device adjusts the temperature, humidity, air quality, etc. in the mangrove planting ecological cabin according to the environmental regulation instructions, and the lighting device performs corresponding dimming control. For example, when it is necessary to reduce the temperature in the cabin, the temperature regulation device starts the refrigeration function; when it is necessary to increase the humidity, the humidity regulation device starts the humidification function; when it is necessary to adjust the light intensity, the light source control unit changes the current or voltage of the LED plant growth lamp to achieve dimming.

[0065] Salinity adjustment

[0066] The salinity detection unit in the salinity adjustment device continuously monitors the water salinity. Once it is found that the salinity deviates from the appropriate range, the salinity adjustment execution unit adjusts according to the salinity adjustment instructions issued by the mangrove planting management system. For example, when the salinity detection unit detects that the water salinity increases, the salinity adjustment execution unit starts the fresh water adding device and adds fresh water to the water in the cabin at a certain ratio until the salinity reaches the appropriate range.

[0067] Resource recycling

[0068] Recycle the irrigation liquid. Excess irrigation liquid can be collected into a recycling container through a drainage pipe set at the bottom of the planting tank. Then, the recycled irrigation liquid is treated through filtration, disinfection, etc., and is recycled for the automatic preparation of nutrient solution. After supplementing appropriate nutrient elements according to the growth stage and requirements of mangroves, it is used for the tidal irrigation in the later stage of mangrove seedling cultivation, realizing the recycling of water resources and nutrient solution and reducing the seedling cultivation cost. Specific Embodiment

[0070] Preparation Stage

[0071] Assemble the ecological cultivation and seedling raising system for mangrove planting. Inside an indoor mangrove planting ecological cabin, install the mangrove planting management system, fix the imaging unit (high-definition camera) in a suitable position to ensure that the entire picture of the mangrove seedlings in the planting tank can be clearly captured. The planting analysis module and the planting control module are installed in the control box and are connected to the imaging unit and other related devices.

[0072] Install the mangrove hydroponic seedling device. Place the horizontally placed planting tank at the designated position in the ecological cabin, and fill the planting tank with a suitable growth substrate for mangroves (such as a sand-silt mixed substrate). Connect the irrigation liquid circulation unit, including connecting the water pumping device (a submersible pump with a power of 500W), the water storage device (a 1000L water supply and storage tank), and the circulation pipeline (a PVC pipe with a diameter of 2.5 cm). The water inlet pipeline in the circulation pipeline is connected to the water supply and storage tank, and the spray irrigation pipeline is evenly distributed with nozzles at the top of the planting tank. The tidal irrigation pipeline is laid at the position of the mangrove planting tray (a planting tray that can simulate tides can be set at the bottom of the planting tank). An electromagnetic valve is installed on the circulation pipeline and is connected to the irrigation control unit. The water pumping device is also connected to the irrigation control unit.

[0073] Install the environmental adjustment device. Install a temperature adjustment device (air conditioner), a humidity adjustment device (humidifier and dehumidifier), an air quality adjustment device (air purifier and ventilation fan), and a lighting device (LED plant growth lamp) in the ecological cabin. The light source control unit of the lighting device is connected to the environmental adjustment device to receive environmental adjustment instructions to achieve dimming control.

[0074] Install the salinity adjustment device. Install the salinity detection unit (a high-precision salinity sensor) at a suitable position in the water body of the planting tank. The salinity adjustment execution unit (including a salt solution addition device and a fresh water addition device) is connected to the salinity detection unit and the mangrove planting management system.

[0075] Seedling Cultivation Process

[0076] Select mangrove seedlings (such as Avicennia marina seedlings) and plant them in the growth substrate in the planting tank.

[0077] The system is started, and the imaging unit begins to regularly (every two days) obtain the mangrove seedling raising images. The planting analysis module analyzes the images based on machine vision algorithms, identifies the mangrove species as Avicennia marina, and the current growth state characteristics, such as the seedling height being 5 cm, the cotyledons not yet unfolded, and the leaf color being light green, etc.

[0078] According to the mangrove species and growth state characteristics, by referring to the preset maturity level standard (when the cotyledons of Avicennia marina are not unfolded, it is a low maturity level), it is determined that the current maturity level of the mangrove seedling raising is low and does not meet the preset level (the maturity level corresponding to the cotyledon unfolding state).

[0079] The planting control module generates a spray irrigation control instruction, setting to spray 4 times a day, each time for 12 minutes. At the same time, according to the growth environment requirements of Avicennia marina (suitable temperature 25°C - 30°C, relative humidity 80% - 90%, strong light), it generates an environmental regulation instruction. The temperature regulation device controls the temperature in the cabin at 25°C - 30°C, the humidity regulation device maintains the relative humidity at 80% - 90%, and the lighting device provides strong light (light intensity of 3000 - 5000 lux).

[0080] After the irrigation control unit receives the spray irrigation control instruction, it controls the clear water in the irrigation circulation unit to enter the spray irrigation pipeline from the water supply and storage water tank through the water pumping device, and performs spray irrigation at the top of the planting tank.

[0081] The salinity detection unit of the salinity regulation device monitors the water salinity in real time, maintaining it within the suitable salinity range for the growth of Avicennia marina (15‰ - 25‰). If the salinity fluctuates, the salinity regulation execution unit adjusts it in a timely manner.

[0082] Growth stage transition

[0083] After a period of time (about two weeks), the mangrove seedlings grow and the cotyledons begin to unfold. The imaging unit obtains the images again, and the planting analysis module identifies the cotyledon unfolding situation. According to the corresponding relationship between the maturity level and the cotyledon growth characteristics, it is judged that the maturity level of the mangrove seedlings reaches the preset level.

[0084] The planting control module generates a tidal irrigation control instruction, performing 2 tidal irrigations a day, and each tidal ebb and flow time is 2.5 hours. At the same time, it adjusts the environmental regulation instruction according to the growth requirements of the mangroves, such as appropriately reducing the light intensity (2000 - 3000 lux).

[0085] After the irrigation control unit receives the tidal irrigation control instruction, it controls the nutrient solution in the irrigation circulation unit to enter the tidal irrigation pipeline from the storage water tank through the water pumping device for tidal irrigation.

[0086] Resource recycling

[0087] During the seedling raising process, a recycling device is set up to collect the excess irrigation liquid after each spray irrigation and tidal irrigation through the drainage pipe at the bottom of the planting tank into a recycling container.

[0088] Regularly (weekly), filter and disinfect the recycled irrigation liquid, and then recycle it for the automatic preparation of nutrient solution. After supplementing the required nutrient elements according to the current growth stage of the mangrove, it is used for the tidal irrigation in the later stage of mangrove seedling raising.

[0089] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
