[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0024] This embodiment also provides a remote water and fertilizer control method and system. Communication technology is required in the remote water and fertilizer control scheme; various existing communication technologies can be used. In the following implementation, LoRa communication technology will be used as an example.

[0025] LoRa is a low-power local area network wireless standard. Its name "LoRa" stands for Long Range Radio. Its biggest feature is that it can transmit over a longer distance than other wireless methods under the same power consumption conditions, achieving a balance between low power consumption and long distance. It can extend the distance by 3-5 times compared to traditional wireless radio frequency communication under the same power consumption.

[0026] The following describes a remote water and fertilizer control system using LoRa. This system integrates sensor technology, LoRa communication technology, and cloud platform application technology to build a complete remote irrigation system from top to bottom. The system consists of a cloud platform, data acquisition terminals, video monitoring, fertilizer applicators, a filtration system, valve controllers, solenoid valves, and field pipelines. Environmental conditions are detected by devices such as air temperature and humidity sensors, soil temperature and humidity sensors, light sensors, CO2 sensors, and pressure sensors. The data is then wirelessly transmitted to the field controller via an MCU and LoRa module. Valve control nodes receive and process control commands from the gateway controller through the MCU and LoRa module, controlling the solenoid valves to irrigate the crops. Simultaneously, the control nodes can monitor the status of each solenoid valve. The cloud platform server centrally manages the data, and user-end software has been developed. Users can query environmental parameters and equipment operating status via computer and mobile app, customize irrigation conditions according to crop needs, and the system also supports automatic irrigation for quantitative irrigation.

[0027] In this embodiment, the following two aspects can also be processed: first, the data conversion and processing of the porosity, moisture content, and soil moisture sensor values ​​of the seedling substrate; second, the water requirement range of the substrate during crop seedling growth, and the establishment of a relationship equation between the porosity of the crop seedling substrate and the precise water requirement. Based on the collected sensor data and relevant research data, the cloud platform establishes a relevant water and fertilizer model, uses computer control technology to precisely inject water and fertilizer into the container, and simultaneously transmits the data to the cloud in real time to remind management personnel, achieving precise irrigation and saving water and fertilizer.

[0028] In this embodiment, automatic early warning and control of water and fertilizer demand can also be performed: in conjunction with soil sensors in the substrate, combined with season, light, temperature and other factors, an early warning can be given when the seedlings’ water demand is close to the minimum limit; and an automated device can be used to recycle, disinfect and prioritize the reuse of the remaining fertilizer and water in the seedbed.

[0029] Figure 3 This is a flowchart of a remote water and fertilizer control method according to an embodiment of this application, such as... Figure 3 As shown below, Figure 3 The steps involved in the method described are explained.

[0030] Step S302: Obtain the plant variety and generate multiple seedling conditions based on the plant variety. The seedling conditions include at least one of the following: seedling substrate porosity and seedling soil moisture content. Each seedling condition is different.

[0031] Step S304: Under the same environmental conditions, seedlings of the plant varieties are raised according to each seedling raising condition. During the seedling raising process, the seedlings corresponding to each seedling raising condition are photographed on a daily basis.

[0032] Step S306: After the seedling cultivation is completed, generate a set of photos of the seedlings taken under each seedling cultivation condition.

[0033] Step S308: Analyze the photo set, select the photo set with the best seedling effect and save the corresponding seedling conditions.

[0034] Through the above steps, the optimal seedling conditions for each plant variety can be obtained through experiments, and the best seedling plan can be determined through photo analysis, thereby making seedling cultivation more scientific and improving seedling quality.

[0035] Optionally, after step S308, the plant variety to be cultivated is obtained, and a search is performed on the saved cultivation conditions according to the plant variety. If a cultivation condition corresponding to the plant variety is found, the cultivation process of the plant variety to be cultivated is controlled according to the found cultivation conditions.

[0036] Optionally, if no corresponding seedling conditions are found, plant varieties with a similarity exceeding a threshold to the plant variety to be cultivated are obtained, and seedling conditions corresponding to the plant varieties with a similarity exceeding the threshold are searched. If a seedling condition is found, the seedling process of the plant variety to be cultivated is controlled according to the searched seedling conditions.

[0037] Optionally, the soil moisture content in each seedling condition is a time-varying moisture content. That is, the moisture content is different at different stages of seedling cultivation. Optionally, the seedling conditions may further include the content of a predetermined substance in the seedling soil, wherein the content of the predetermined substance is used to indicate the fertilization status of the seedling soil.

[0038] Optionally, the seedling conditions corresponding to the photo set with the best seedling effect are selected and the following steps are taken: analyzing the seedling height and leaf area in each picture. If the seedling height and leaf area of ​​a picture in a photo set are better than those of pictures taken at the same time in other photo sets, then the picture is called the first picture. The seedling conditions corresponding to the photo set with the most first pictures are selected as the seedling conditions with the best seedling effect.

[0039] As an optional implementation, analyzing the height of the seedling in each photo includes: training a first neural network model using multiple sets of first training data, each set of training data including a photo of a plant seedling and a label, wherein the plant seedling photo includes a plant seedling and a ruler placed next to the plant seedling, and the label is used to indicate the height of the plant seedling; after training, the photo is input into the first neural network model, and the neural network model outputs a label indicating the height of the plant seedling in the photo.

[0040] As another optional implementation, analyzing the leaf area of ​​the seedling in each photo includes: training a second neural network model using multiple sets of second training data, each set of training data including a photo of a plant seedling and a label, wherein the plant seedling photo includes a plant seedling and a ruler placed next to the plant seedling, and the label is used to indicate the leaf area of ​​the plant seedling; after training, the photo is input into the second neural network model, and the neural network model outputs a label indicating the leaf area of ​​the plant seedling in the photo.

[0041] The following embodiments provide a seedling tray (or seedling device) that can be applied to the embodiments described above and below. Of course, seedling trays with other structures can also be used in the embodiments described above and below.

[0042] In the following embodiments, the seedling raising device is referred to as the "waist-absorbing" combined seedling raising device, and this seedling raising device will be used in the following description.

[0043] As an optional implementation, this seedling device can be divided into three parts: the lower part is the seedling tray base, which is trapezoidal in shape with a one-piece bottom and double rows of seedling cups on the wide side (quantity as needed). The long side is 50-100 cm (number as needed). Each cup has a perforation and drainage hole at 1 / 4-1 / 3 of the distance from the bottom. The sides and center are solid, and there are semi-partitions between the seedling cups. The partitions are 1-1.5 cm higher than the drainage holes from the bottom up. The material is chosen to facilitate recycling. The middle part is the auxiliary seedling cup, which has its bottom removed and matches the specifications of the base. Its height is 2-4 cm higher than the four sides of the base. It is made of 6-8 mil biodegradable plastic film blow molding. The upper part is the fixing clamp, which is made of rigid micro-elastic plastic. In use, the auxiliary seedling cup is placed on the seedling tray base, and the part of the upper part that is longer than the seedling cup is pulled down and fixed with the clamp to form a complete seedling tray. This combination seedling tray comes with a tidal seedling bed, and the water supply is completed by self-suction through the permeable holes on the side of the bottom tray.

[0044] As can be seen from the above-described seedling device, it uses three parts: a lower seedling tray base, a middle seedling cup, and an upper fixing clamp. The seedling cup is used to fit over the seedling cup on the seedling tray base. The portion of the seedling tray base longer than the seedling cup is bent downwards and secured by the fixing clamp. The seedling cup on the seedling tray base has an opening at 1 / 4 to 1 / 3 of its distance from the bottom of the base. Using these three parts allows for reasonable control of the water volume in the seedling tray, thus solving related technical problems.

[0045] Optionally, the bottom of the seedling tray base is integral, with one or more rows of seedling cups on the wide side and the long side determined according to requirements. The seedling tray base is solid around its perimeter and in the middle, and a semi-partition is provided between each row of seedling cups. The semi-partition is 1 cm to 1.5 cm higher than the hole from the bottom up.

[0046] Optionally, the seedling cup has a bottom removed and its sides are matched to the base, with its height exceeding the four sides of the base by 2-4 cm. Optionally, the seedling cup is made of 6-8 mil biodegradable plastic film blow-molded.

[0047] Optionally, the clamp is made of elastic plastic.

[0048] Compared with traditional seedling raising devices, this device can reduce water return, lower seedling humidity, and improve water and fertilizer utilization, thereby improving the quality of seedling raising.

[0049] Through the above implementation method, it is expected that water and fertilizer can be saved by about 30%; the central auxiliary seedling cup can be directly removed for seedling transportation without damaging the seedlings, reducing secondary packaging and lowering costs; the side opening can solve the problem of root entanglement.

[0050] In this embodiment, a method for using the above-mentioned seedling tray is also provided. Figure 2 This is a flowchart of a method for using a seedling tray according to an embodiment of this application, such as... Figure 2 As shown below, the steps involved in this method are explained.

[0051] Step S202: Based on the variety of the plant seedlings planted in the seedling tray, obtain the expected growth height and ventilation conditions of the plant seedlings according to the variety.

[0052] As an optional implementation, the system including the seedling tray includes a server for providing software services. This server can provide a page for users to input the variety of the plant seedling. In another optional implementation, the shelf holding the seedling tray is also equipped with a camera. The camera takes pictures of the seedling tray on the shelf at a predetermined time each day and sends the pictures to the server. The server compares the pictures with previously taken pictures. If the comparison determines that the variety of the plant seedling in the tray has changed, the server obtains the expected growth height and ventilation conditions for the plant seedling based on the variety planted in the tray.

[0053] Machine learning can be used to identify the variety of plant seedlings. A supervised neural network model is trained using multiple sets of training data. Each set of training data includes an image and a label (which may be called a first label). The label is used to indicate the variety of plant seedlings in the image. After training, the server inputs the captured images into the neural network model. The label output by the neural network model is used to indicate the variety of plant seedlings in the input images.

[0054] In another alternative implementation, if it is determined that the variety of the plant seedling has not changed, the image is compared with an image taken N days ago to determine the growth status of the plant seedling, and information is sent based on the growth status, wherein the information carries the growth status.

[0055] As another application of the neural network model, a supervised neural network model is trained using multiple sets of training data. Each set of training data includes a first image, a second image, and a label (which can be called a second label). The label is used to indicate the growth status of the plant seedling in the image. After training, the server inputs the two images into the neural network model, and the label output by the neural network model is used to indicate the growth status of the plant seedling in the input image.

[0056] Step S204: Determine the vertical distance between each layer of seedling trays based on the growth height and ventilation conditions.

[0057] Step S206: Adjust the height between each layer of the shelf used to place the seedling tray according to the distance in the vertical height, wherein each layer of the shelf moves vertically by the drive of the motor.

[0058] Step S208: After the height adjustment between the shelves where the seedling trays are placed is completed, a prompt message is sent.

[0059] By following the steps above, the height between the shelves can be automatically adjusted, thereby improving adjustment efficiency and reducing labor costs.

[0060] Optionally, the notification message is used to indicate to the user that the shelf adjustment is complete. Alternatively, the notification message may also carry the adjusted height between each shelf level. If the user needs to adjust the height, the user sends a command to drive the motor to adjust the vertical distance between each shelf level.

[0061] In another embodiment, the moisture content can also be adjusted by controlling the ambient temperature, which is referred to in this embodiment as micro-evaporation water circulation seedbed temperature control technology.

[0062] In this embodiment, the bottom of the seedling tray can be configured as a stepped structure, with seedling cups placed on different steps of the stepped structure, thereby controlling the gap between the bottom of the seedling tray and the seedling cups. Through this embodiment, in the seedbed, the gap between the bottom and top of the seedling tray is combined using a small ladder shape, and water at a certain temperature flows and circulates in the limited gap at the bottom of the combined seedling tray, achieving close-range and low-cost temperature control for seedling growth. This aims to achieve a harmonious win-win situation of energy-saving temperature regulation and environmental dehumidification, disease reduction, and pesticide savings.

[0063] In this embodiment, the circulating water volume and temperature are controlled in relation to changes in substrate temperature; the correlation between circulating water volume and temperature and seedling vigor is recorded. Using the correlation model developed in this study, combined with sensor data and the growth characteristics and requirements of seedlings at different stages, intelligent temperature regulation of the seedling root microenvironment is achieved.

[0064] Figure 4 This is a flowchart of a seedbed temperature control method based on evaporation water circulation according to an embodiment of this application, as follows: Figure 4 As shown below, Figure 4 The steps involved in the method described are explained.

[0065] Step S402: Obtain the temperature in the seedbed (which can be understood as a frame for placing seedling trays); wherein the seedling tray includes a lower part, a middle part, and an upper part, wherein the lower part is the base of the seedling tray, the middle part is the seedling cup, and the upper part is a fixing clamp, wherein the seedling cup is used to fit onto the hole cup of the seedling tray base, and the portion of the seedling tray base longer than the seedling cup is bent downwards and fixed by the fixing clamp; the hole cup of the seedling tray base has an opening at 1 / 4 to 1 / 3 of the distance from the bottom of the seedling tray base, and the bottom of the seedling tray is set as a stepped structure, and the seedling cup is placed on different steps of the stepped structure to control the gap between the bottom of the seedling tray and the seedling cup;

[0066] Step S404: Determine whether the temperature meets the predetermined conditions;

[0067] Step S406: If the temperature is higher than the highest temperature in the predetermined conditions, increase the water flow in the gap; wherein, increasing the water flow increases the evaporation rate, thereby lowering the temperature;

[0068] Step S408: If the temperature is lower than the minimum temperature in the predetermined conditions, reduce the water flow in the gap, wherein reducing the water flow reduces evaporation, thereby increasing the temperature.

[0069] The temperature can be adjusted by increasing or decreasing the water flow through the above steps. This temperature adjustment is quite precise and can effectively control the temperature.

[0070] Optionally, if the temperature is higher than the maximum temperature, and the difference between the temperature and the maximum temperature is less than a first predetermined value, the water flow in the gap is increased; if the difference between the temperature and the maximum temperature is greater than or equal to the first predetermined value, the heating device is activated to adjust the temperature.

[0071] Optionally, if the temperature is lower than the minimum temperature, and the difference between the minimum temperature and the temperature is less than a second predetermined value, the flow of water in the gap is reduced; if the difference between the minimum temperature and the temperature is greater than or equal to the second predetermined value, the cooling device is activated to adjust the temperature.

[0072] Optionally, it can be determined whether the water volume in the gap has reached the maximum water capacity of the gap. If it has, a warning message is sent, wherein the warning message is used to indicate that the seedling cup needs to be moved to a higher step in order to increase the maximum water capacity of the gap.

[0073] Optionally, if a robotic arm is configured on the seedbed, and the water volume in the gap has reached the maximum water capacity of the gap, a control command is sent to the robotic arm, wherein the control command is used to instruct the seedling cup to be moved to a higher step to increase the maximum water capacity of the gap.

[0074] In this optional implementation, it is clear that increasing or decreasing the amount of water in the gap can fine-tune the temperature. If a larger adjustment is required, a heating or cooling device is needed.

[0075] Researching automated control equipment systems for factory-scale seedling cultivation not only saves equipment costs and reduces labor costs, but also enables standardized production, which has practical theoretical value and guiding significance for the development of the facility vegetable industry.

[0076] In practical applications, the methods, principles, mechanisms, algorithms, and models adopted aim to achieve factory-scale seedling production, and control is carried out from aspects such as the development of waist-absorbing combined seedling trays, precise water and fertilizer management, and micro-evaporation water circulation seedbed temperature control technology.

[0077] Among them, the waist-absorbing combined seedling tray: In response to the problems of ordinary plug trays and tidal seedling trays in current factory seedling production, such as difficulty in controlling substrate moisture content, serious waste of fertilizer and water, root entanglement, inconvenience in seedling removal and transportation, and large temperature and humidity fluctuations in the seedling root environment, a waist-absorbing seedling tray device was developed. It changes the bottom water absorption to side water absorption. The whole is composed of three parts: bottom support, seedling cup, and cup cover. The bottom of the bottom support is flat, which reduces water return and lowers humidity. The seedling cup can be directly removed for seedling transportation, reducing secondary damage to the roots and saving labor costs. The side opening can solve the problem of root entanglement. At the same time, the temperature-regulating water and irrigation fertilizer water can be stored separately and automatically circulated according to the position of the hole.

[0078] The automatic irrigation control system for seedling cultivation includes irrigation, water and fertilizer early warning, automatic fertilizer and water recycling, and disinfection control. Addressing common problems in seedling irrigation, it establishes relevant water and fertilizer models through container calculations and utilizes computer control technology to precisely inject water and fertilizer into the container, while simultaneously transmitting data to the cloud in real time to alert management personnel. Excess water and fertilizer are returned to a recycling tank for disinfection and reuse, thus achieving precise irrigation and saving water and fertilizer.

[0079] Among these methods, the use of flowing water to control the temperature of the seedling trays allows the seedlings to germinate and grow at a suitable temperature. The water flows in the container, which reduces evaporation, lowers the humidity in the air, reduces diseases, controls the cost of heating and cooling, improves the microenvironment of the seedling rhizosphere, and enhances the uniformity, seedling strength, robustness, and yield of seedlings.

[0080] In this embodiment, an electronic device is provided, including a memory and a processor. The memory stores a computer program, and the processor is configured to run the computer program to perform the methods described in the above embodiments.

[0081] The aforementioned program can run on a processor or be stored in memory (or a computer-readable medium). Computer-readable media includes both permanent and non-permanent, removable and non-removable media, and information storage can be achieved by any method or technology. Information can be computer-readable instructions, data structures, program modules, or other data. Examples of computer storage media include, but are not limited to, phase-change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technologies, CD-ROM, digital versatile optical disc (DVD) or other optical storage, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other non-transfer medium that can be used to store information accessible by a computing device.

[0082] These computer programs may also be loaded onto a computer or other programmable data processing equipment to cause a series of operational steps to be performed on the computer or other programmable equipment to produce a computer-implemented process, thereby providing instructions that execute on the computer or other programmable equipment for implementing the process. Figure 1 One or more processes and / or boxes Figure 1 The steps for the functions specified in one or more boxes can be implemented using different modules, and different steps can be implemented using different modules.

The bottom of the seedling tray is designed with a stepped structure, allowing the seedling cup to be placed on different steps of the stepped structure to control the gap between the bottom of the seedling tray and the seedling cup.

[0095] A judgment module is used to determine whether the temperature meets a predetermined condition;

[0096] The processing module is configured to, if the temperature is higher than the highest temperature in the predetermined conditions, increase the water flow in the gap, wherein increasing the water flow increases evaporation to lower the temperature; and if the temperature is lower than the lowest temperature in the predetermined conditions, decrease the water flow in the gap, wherein decreasing the water flow decreases evaporation to raise the temperature.
