[0027] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a full understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more specific details omitted, or other methods, components, apparatus, steps, etc., can be employed. In other instances, well-known technical solutions are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0028] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0029] In an exemplary embodiment of this disclosure, the site can be selected as a saline-alkali low-lying area with an area of ​​not less than 1 hectare to facilitate water storage, and the daily water supply is required to be not less than 500 cubic meters, and the local annual average sunshine should be not less than 2800 hours, and the annual average temperature should be between 8 and 13 degrees Celsius.

[0030] Before construction, key indicators such as effective soil salinity, electrical conductivity, pH value, and water salinity and ammonia nitrogen need to be tested. Based on the overall layout, the wiring, pipelines, roads, fish ponds, purification ponds, rice fields and other areas should be planned in advance to ensure the optimal pipeline route.

[0031] Figure 1 The diagram schematically illustrates a top view and a cross-sectional view of an exemplary embodiment of the present disclosure. The core engineering work involves excavating a ring-shaped fishpond. In this embodiment, it adopts a ring-shaped double-pond or a single-pond plus a purification pond form. The inner pond has a circumference of 200 meters, a clean water depth of 1.5 meters, and a dam width of 3 meters. It needs to be compacted to a density of not less than 90%. The pond body needs to be treated for seepage prevention, including soft soil foundation reinforcement and laying C25 plain concrete, geotextile, and composite geomembrane.

[0032] In the top view of the exemplary embodiments disclosed herein, the dark area represents a ring-shaped double-pond structure. The inner pond is the aquaculture pond, and the outer pond is the microbial purification pond. The aquaculture pond can employ a polyculture model of Litopenaeus vannamei and tilapia, with a density of approximately 3,000 shrimp and tilapia per hectare. Feed is provided daily at 3% to 5% of the shrimp's body weight in several portions. The shrimp can be harvested after approximately 120 days of culture and must be sorted and subjected to cold chain processing.

[0033] A crop planting zone is located within the aquaculture pond and the microbial purification pond. Outside the microbial purification pond is a pond embankment. Rice planting strips with a width of 2 meters are reserved on both sides of the pond embankment, and a 30-centimeter-thick layer of improved loam is laid for planting salt-tolerant rice varieties.

[0034] According to an exemplary embodiment of this disclosure, a photovoltaic panel array is installed on an aquaculture pond for power generation. The modules can be polycrystalline silicon or PERC silicon panels with a single panel power of 400 watts and an efficiency of not less than 20%, installed at a 30-degree tilt angle facing south, with a row spacing of 3 meters to ensure light transmission. The support structure uses galvanized square tubing combined with concrete-filled pile foundations. The shading effect of the photovoltaic panel array can effectively reduce the water surface evaporation and salt return rate by approximately 20%.

[0035] exist Figure 1 In this system, the microbial purification pond and the aquaculture pond are connected by pipelines. First, the saline-alkali land integrated farming system uses a lift pump to transport the first body of water from the fishpond to the microbial purification pond. The ratio of the purification pond's volume to the fishpond's volume can be 1:10, and the interior is lined with gravel and aquatic plants. The water retention time in the microbial purification pond can be preset to 24 hours, during which the nitrification-denitrification process is carried out to ensure that the ammonia nitrogen removal rate is not less than 85%.

[0036] Next, after the nitrification-denitrification process is completed, the second body of water, from which ammonia nitrogen has been removed, is transported to the mixing tank through pipelines, where the water is diluted to obtain the third body of water.

[0037] Finally, through Figure 1 Two pipes connecting the crop planting strips on the pond embankment and the crop planting strips on the pond dike will use the third water body for irrigation.

[0038] It is important to note that integrated farming systems on saline-alkali land require appropriate combiner boxes, cables, and inverters, and grounding and lightning protection must be strictly implemented in accordance with national standards. Routine maintenance includes cleaning the photovoltaic modules twice a quarter and inspecting the support structures for corrosion and electrical connections.

[0039] Figure 2 A block diagram of an integrated farming system for saline-alkali land according to an exemplary embodiment of the present disclosure is shown schematically.

[0040] In an exemplary embodiment of this disclosure, the saline-alkali land integrated farming system may include an aquaculture subsystem, a photovoltaic power generation system, a crop planting subsystem, and a water circulation subsystem.

[0041] According to an exemplary embodiment of this disclosure, the aquaculture subsystem may include an aquaculture pond.

[0043] The water circulation subsystem includes a lift pump, a microbial purification tank, a mixing tank, and an irrigation device. The lift pump transports the first water body from the aquaculture pond to the microbial purification tank, which removes ammonia nitrogen from the first water body through nitrification and denitrification. The mixing tank receives the second water body after ammonia nitrogen removal and dilutes it based on the preset irrigation salinity of the crop planting subsystem to obtain a third water body. The irrigation device transports the third water body to the crop planting subsystem.

[0044] According to exemplary embodiments of this disclosure, the water circulation subsystem may also include isolation pools based on disease prevention and control plans. Figure 3 A schematic diagram showing the distribution of the isolation pools added in an exemplary embodiment of this disclosure is illustrated. Figure 3 In accordance with an exemplary embodiment of this disclosure, the drugs can be rotated every 15 days, and the isolation pool can be used to receive abnormal aquaculture objects when abnormal aquaculture objects are identified in the aquaculture pond. The isolation pool is connected to the aquaculture pond through a controllable pipeline.

[0045] According to an exemplary embodiment of this disclosure, a controllable pipeline regulates the flow rate of the pipeline via a pipeline control device. Upon receiving a target control command, the control device responds to the target control command by regulating the flow rate of the pipeline within the water circulation subsystem.

[0046] According to an exemplary embodiment of this disclosure, the water circulation subsystem may further include a water monitoring device. The water monitoring device can be used to acquire water parameters of the water circulation subsystem and send the water parameters to a local terminal or a remote terminal; an alarm device is used to generate alarm information when the water parameters exceed a preset safety threshold and to map the alarm information to a target control command.

[0047] In addition, by deploying IoT sensors for salinity, pH, dissolved oxygen, and water level, and using NB-IoT / GPRS wireless transmission to the cloud platform, data visualization and real-time alarms can be achieved. The control system can automatically link gates and water pumps; for example, it can automatically start freshwater replenishment when salinity exceeds the standard, and can intelligently schedule photovoltaic power to prioritize the use of electricity consumed in aquaculture, such as nighttime oxygenation.

[0048] According to exemplary embodiments of the present disclosure, the water monitoring device may further include a salinity sensor, and the water circulation subsystem may further include a freshwater tank. Figure 4 A schematic diagram of the distribution of the freshwater tank added in an exemplary embodiment of this disclosure is shown. The inlet of the freshwater tank is connected to an external freshwater source, and the outlet of the freshwater tank is connected to a mixing tank for mixing with the second water body from the isolation tank to form a third water body. In an exemplary embodiment of this disclosure, the added freshwater tank can dilute the second water body in the isolation tank. Meanwhile, without adding a separate freshwater tank, the dilution method for the second water body in this disclosure can be any feasible method of providing freshwater.

[0049] According to an exemplary embodiment of the present disclosure, a pipeline control device located at the outlet of a freshwater tank can be configured to adaptively adjust the freshwater delivery rate based on the difference between the salinity of the second water body read by a salinity sensor and a preset irrigation salinity.

[0050] According to exemplary embodiments of this disclosure, the crop planting subsystem may further include a harvesting device. The harvesting device can be used to perform harvesting operations when the crops in the crop planting zone are mature. Rice is harvested mechanically at the same time, and the rice is dried to a moisture content of less than 16% before being stored. The stubble can be plowed back into the field and used in conjunction with the sludge from the purification pond to improve soil structure.

[0051] According to exemplary embodiments of this disclosure, the crop planting subsystem may further include a tillage device. The tillage device can be used to return crop residues generated by the harvesting device to the crop planting zone. The tillage device may be configured to receive and apply bottom sediment from a microbial purification pond to synergistically improve the planting zone soil in saline-alkali land.

[0052] According to exemplary embodiments of this disclosure, the crop planting subsystem may further include a seedling area. Figure 5 A schematic diagram showing the distribution of the seedling area added in an exemplary embodiment of this disclosure is shown.

[0053] This system features an independent, controllable seedling raising area. The seedling raising area uses soilless seedling substrate with a salinity below 1.0 mS / cm and low-salinity purified water from the system's mixing tank to cultivate robust, salt-tolerant seedlings suitable for transplanting into saline-alkali land, overcoming the survival rate bottleneck of direct sowing in saline-alkali soil. The seedling raising area can be used to cultivate crop seedlings to a suitable transplanting age.

[0054] According to exemplary embodiments of this disclosure, the crop planting subsystem may further include an integrated water and fertilizer device. The integrated water and fertilizer device can be used to mix purified water from the water circulation subsystem with fertilizer in a preset ratio during the later stages of crop growth, and then apply topdressing to the crops.

[0055] According to exemplary embodiments of this disclosure, the aquaculture subsystem may further include an automatic feeding device. The automatic feeding device can be used to feed the aquaculture pond according to a preset feed dispensing strategy.

[0056] According to exemplary embodiments of this disclosure, the aquaculture subsystem may further include an oxygenation device. The oxygenation device can be used to oxygenate the aquaculture pond in response to a preset program, so as to maintain the dissolved oxygen level in the aquaculture pond at or above a dissolved oxygen threshold.

[0057] This invention adopts a modular and standardized design, and through photovoltaic revenue subsidies and integrated water and fertilizer recycling technology, it significantly improves the comprehensive utilization efficiency of saline-alkali land and achieves the goal of synergistic win-win between "fishery-agriculture-photovoltaics-ecology".

[0058] Furthermore, this example embodiment also provides a method for determining the benefits of a three-dimensional farming system on saline-alkali land.

These parameters are obtained directly from system operation monitoring data or calculated, for example, by reading harvest records or meter readings.

[0062] S62. Determine the production score of the saline-alkali land three-dimensional farming system based on the first production parameter, the second production parameter, and the third production parameter, as well as the preset weights corresponding to the first production parameter, the second production parameter, and the third production parameter.

[0063] According to an exemplary embodiment of this disclosure, firstly, the first production parameter, the second production parameter, and the third production parameter are normalized to the same numerical range, for example, 0-100 points.

[0064] Subsequently, a weighted summation model is used to calculate the production score:

Determine the first soil improvement parameter of the water circulation subsystem and the second soil improvement parameter of the crop planting subsystem in the saline-alkali land integrated farming system, and determine the soil improvement score of the saline-alkali land integrated farming system based on the first soil improvement parameter and the second soil improvement parameter.

[0068] According to an exemplary embodiment of this disclosure, the first soil improvement parameter can be the rate of decrease in soil salinity in the planting zone after one cycle of operation through the water circulation subsystem. The first soil improvement parameter benefits from the leaching of salts in the root zone by purified irrigation water.

[0069] The second soil improvement parameter is the rate of increase in organic matter content in the planting zone soil after one cycle of operation of the crop planting subsystem. This second soil improvement parameter benefits from rice stubble return and organic fertilizer application. Soil Improvement Score Geometric mean or weighted average models can be used to calculate the parameters to reflect their synergy, for example:

[0073] It should be noted that although the steps of the method in this disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or a step may be broken down into multiple steps.
