[0002] Plant residues are the initial source of soil organic carbon, and microbial assimilation products are also important contributors to the soil stable organic carbon pool. Reintroducing decaying microbial communities into the soil is crucial for enhancing the long-term carbon storage potential of the soil and stabilizing it over time, which means that by optimizing the input of plant residues and the activity of microbial communities, the soil carbon sequestration capacity can be improved.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0022] An embodiment of the present application provides a device for improving the soil carbon sequestration capacity by using vegetation residues and microorganisms, which can solve the problems that the prior art cannot accurately regulate the activity of the microbial community, increases carbon emissions, and cannot improve the utilization capacity of soil organic matter.

[0023] Since the prior art generally mixes the plant residues after crushing and drying with organic fertilizer and pig manure and uses a forced ventilation static composting system for composting. It is unable to accurately regulate the activity of the microbial community, and there is a situation where the process of microbial decomposition and carbon release is greater than the process of synthesis and nitrogen fixation, increasing carbon emissions. Therefore, it is necessary to make the microorganisms tend to convert more carbon into soil organic matter through anabolic metabolism. Then a device that can control the temperature and humidity is designed, which can independently control the optimal temperature and humidity for the anabolic reaction of microorganisms, and add beneficial microorganisms to promote the decomposition ability of soil organic matter to ensure the activity of the microbial community, thereby greatly improving the soil carbon sequestration capacity.

[0024] Reference Figure 1 , a device for improving the soil carbon sequestration capacity by using vegetation residues and microorganisms, which includes: a fermentation tank 1, inside which there is a soil-turning component 2 for turning the mixture of plant residues and soil placed in the fermentation tank 1; a humidity meter 6 and a thermometer 7 are arranged inside the fermentation tank 1; a temperature control component 3 for sending cold air or hot air into the fermentation tank 1 according to the temperature detected by the thermometer 7; a water adding device 5 which is arranged on the fermentation tank 1 and is communicated with the inside of the fermentation tank 1.

[0025] Through the design of this device, among them, the fermentation tank 1 serves as a microbial reaction device for containing the mixture of plant residues and soil and providing appropriate environmental conditions to promote the anabolic reaction of microorganisms. The soil-turning component 2 is responsible for turning the mixture of plant residues and soil in the fermentation tank 1 to increase the oxygen content and promote the decomposition and activity of aerobic microorganisms. The temperature control component 3 is used to adjust the temperature inside the fermentation tank 1 to provide the required thermal environment for the best performance of microbial activity. The water adding device 5 can manually add an appropriate amount of water according to the humidity requirement of the soil to maintain the appropriate humidity of the mixture. The humidity meter 6 monitors the humidity of the mixture inside the fermentation tank 1 in real time to provide data support for the operation of the water adding device 5; the thermometer 7 is used to monitor the temperature state inside the fermentation tank 1 in real time to facilitate linkage with the temperature control component 3 to achieve autonomous regulation. By using this device, the decomposition rate of plant residues can be effectively increased, the soil carbon sequestration capacity can be enhanced, thereby combating soil degradation and climate change. Ensure that the activity of microorganisms can play a role under the best conditions, so as to achieve the full utilization of resources and the sustainable development of the environment.

[0026] In some preferred embodiments, one side of the fermentation tank 1 is detachably connected to a conduit 8 through a connecting component, and one end of the conduit 8 away from the fermentation tank 1 is detachably connected to a stirring cylinder 9 through a connecting component.

[0027] In this embodiment, the stirring cylinder 9 is used to initially place the collected plant residues and the soil with microorganisms, crush the plant residues and mix them thoroughly with the soil with microorganisms to obtain a mixture of plant residues and soil. And the mixture is transported to the fermentation tank 1 through the detachably connected conduit 8 to react under a specific environment.

[0028] In some preferred embodiments, a first protruding pipe 11 is provided on the side surface of the fermentation tank 1; a second protruding pipe 91 is provided on the circumferential side of the stirring cylinder 9; the pipe orifice diameters of the first protruding pipe 11 and the second protruding pipe 91 are the same and larger than the pipe orifice diameter of the conduit 8; the connecting component includes a clamp 10; one end of the conduit 8 is inserted into the first protruding pipe 11, and the clamp 10 is provided at this insertion port and clamps it; the other end of the conduit 8 is inserted into the second protruding pipe 91, and the clamp 10 is provided at this insertion port and clamps it.

[0029] Through this design, the clamp 10 ensures the stable connection between the first protruding pipe 11 and the second protruding pipe 91 and the conduit 8 by means of clamping and fixing, preventing the leakage of the mixture caused by pressure or vibration. At the same time, the use of the clamp 10 also makes the installation and disassembly of the entire device more convenient. By providing matching protruding pipes on the side surfaces of the fermentation tank 1 and the stirring cylinder 9 and combining the use of the clamp 10, the installation connection and disassembly of the fermentation tank 1 and the stirring cylinder 9 are made more convenient, and the sealing performance of the device is enhanced.

[0030] In some preferred embodiments, the stirring cylinder 9 is a cylindrical structure with an opening at the top, and a clamping groove is provided on the circumference of the opening, and a stirring component 12 is clamped on the clamping groove, which is used to crush and mix the mixture of plant residues and soil placed in the stirring cylinder 9.

[0031] This design of the cylindrical structure provides a larger volume for the stirring cylinder 9, capable of accommodating more mixtures of plant residues and soil. At the same time, the annular internal space helps the circulation and flow of substances, improving the stirring effect. The opening at the top facilitates the operator to put the mixture of plant residues and soil into the stirring cylinder 9, and the setting of the clamping groove enables the stirring component 12 to be firmly fixed on the top of the stirring cylinder 9. The design of the stirring component 12 is to crush and mix the mixture of plant residues and soil placed in the stirring cylinder 9. The shearing force generated by its rotational movement can effectively break up the materials and make them more evenly mixed, promoting the subsequent microbial decomposition process. This physical stirring method can significantly improve the mixing effect and processing efficiency.

[0032] In some preferred embodiments, the stirring assembly 12 includes a cover plate 121, a second motor 122, and stirring rods 123. The cover plate 121 is snap-connected to the snap-fit groove; the second motor 122 is disposed at the central axis of the top of the cover plate 121. The output end of the second motor 122 is connected to the top end of the stirring rod 123. The other end of the stirring rod 123 is rotatably connected to the bottom of the stirring cylinder 9, and a plurality of scraping blades 124 are provided on the stirring rod 123.

[0033] Through this structural design, the cover plate 121 is firmly installed on the top of the stirring cylinder 9 through the snap-fit groove, which facilitates installation and disassembly and also prevents the mixture from splashing out during the stirring process; the second motor 122 serves as a driving source, responsible for providing rotational power to drive the stirring rod 123 to perform stirring and mixing actions. The design of the stirring rod 123 enables it to generate a rotational motion under the drive of the second motor 122, and the scraping blades 124 thereon are rotated through rotation to achieve the crushing and mixing of the materials.

[0034] In some preferred embodiments, the stirring cylinder 9 and the fermentation tank 1 are disposed on the pallet 13; a plurality of universal wheels 14 are provided at the bottom of the pallet 13.

[0035] Through this design, the pallet 13 is the basic platform of the entire device, supporting the stirring cylinder 9 and the fermentation tank 1 to ensure the stability of the equipment; a plurality of universal wheels 14 are installed at the bottom of the pallet 13, usually configured with four wheels, to increase the mobility of the equipment, meeting the usage requirements of users in different scenarios.

[0036] In some preferred embodiments, the temperature control assembly 3 includes a air supply duct 31 and a blower 32; a plurality of air supply ducts 31 are provided on the opposite side of the side of the fermentation tank 1 where the conduit 8 is provided. The other end of each air supply duct 31 is connected to the blower 32; the blower 32 is disposed on the pallet 13.

[0037] In this design, a plurality of air supply ducts 31 are evenly distributed on the side of the fermentation tank 1. It should be noted that the air supply ducts 31 should be disposed at a position close to the top of the fermentation tank 1 to prevent the mixture from being too high and blocking the air supply ducts 31. The blower 32 is installed on the pallet 13. After introducing air and passing it through a heating or cooling device, the blower 32 pushes the air flow to the air supply ducts 31, thereby controlling the temperature inside the stirring cylinder 9. The rotation speed of the blower 32 is adjustable to adapt to different temperature control requirements and improve energy efficiency and response speed. The design of the temperature control assembly 3 realizes the effective management of the temperature of the stirring cylinder 9 by reasonably arranging the air supply ducts 31 and the blower 32 on the fermentation tank 1 and the pallet 13.

[0038] In some preferred embodiments, the soil-turning assembly 2 includes a first motor 21 and a rotating rod 22; the first motor 21 is disposed at the central axis of the top of the fermentation tank 1, the output end of the first motor 21 is connected to the top end of the rotating rod 22, the other end of the rotating rod 22 is rotatably connected to the bottom of the fermentation tank 1, and a plurality of rotating blades 23 are provided on the rotating rod 22.

[0039] With this design, the first motor 21 serves as the main power source to drive the operation of the entire rotating assembly, and the rotation speed of the first motor 21 can be adjusted to control the rotation speed of the rotating rod 22; one end of the rotating rod 22 is connected to the output end of the first motor 21, and the other end is rotatably connected to the bottom of the fermentation tank 1, forming a flexible rotating shaft, and driving the rotating blades 23 located thereon to rotate, realizing the turning action of the mixture, increasing the oxygen content, and promoting the decomposition and activity of aerobic microorganisms.

[0040] In some preferred embodiments, a microbial agent adder 4 is further provided in the fermentation tank 1. The microbial agent adder 4 is a first funnel, which is disposed at the top of the fermentation tank 1; the water adder 5 is a second funnel, which is also disposed at the top of the fermentation tank 1; the moisture gauge 6 includes a first detection rod and a first reader; one end of the first detection rod is fixedly disposed at the bottom of the fermentation tank 1, and the other end of the first detection rod penetrates through the top of the fermentation tank 1 and is connected to the first reader; the thermometer 7 includes a second detection rod and a second reader; one end of the second detection rod is fixedly disposed at the bottom of the fermentation tank 1, and the other end of the second detection rod penetrates through the top of the fermentation tank 1 and is connected to the second reader.

[0041] With this design, the microbial agent adder 4 is used to add a specific carbon-fixing microbial agent, namely a mixed agent of nitrogen-fixing bacteria and arbuscular mycorrhizal fungi, to enhance the biological activity of the soil and improve the carbon-fixing effect. The water adder 5 can manually add an appropriate amount of water according to the moisture requirement of the soil to maintain the appropriate humidity of the mixture. The moisture gauge 6 monitors the humidity of the mixture inside the fermentation tank 1 in real time. If the humidity is lower than 40%, an appropriate amount of water is added to the fermentation tank 1 through the water adder 5. If the humidity is higher than 60%, a certain amount of moisture in the fermentation tank 1 is dried through the temperature control assembly 3, so that the humidity in the fermentation tank 1 is maintained at 40% - 60% to maintain the best state; the thermometer 7 is used to monitor the temperature state inside the fermentation tank 1 in real time, facilitating linkage with the temperature control assembly 3 to achieve autonomous regulation.

[0042] It should be noted that after the evenly stirred mixture is transferred to the fermentation tank 1 through the conduit 8, during which the temperature control component 3 operates to introduce hot air into the fermentation tank 1 and raise the temperature in the fermentation tank 1 to about 50 °C, the soil-turning component 2 is activated to turn the mixture. After the microbial synthesis and metabolism reaction process is completed, the temperature control component 3 introduces cold air into the fermentation tank 1 to rapidly reduce the temperature in the fermentation tank 1. The color of the reactant becomes darker and remains stable. When the temperature in the fermentation tank 1 drops to 25 °C - 30 °C, a carbon-fixing microbial inoculant is added to the inoculant applicator 4. At this time, the soil-turning component 2 is started again to turn the mixture once more. After mixing, a soil mixture with a relatively high carbon-fixing ability is obtained, which is directly used as an ecological mulch to cover the surrounding of plants, helping to maintain soil moisture, providing nutrients, increasing the organic matter content of the soil, storing exogenous carbon in the form of microbial residues in the soil, and improving the carbon storage capacity of the soil. After the exogenously added beneficial microbial inoculant is mixed with the soil, its carbon-fixing and nitrogen-fixing abilities can be exerted, and the number of beneficial microorganisms in the soil can be increased.

[0043] In some preferred embodiments, a first opening is provided on one side of the fermentation tank 1; a discharge pipe 15 is provided on the first opening, and a piston block is provided in the discharge pipe 15 for blocking the first opening.

[0044] With this design, a first opening is provided on one side of the fermentation tank 1, facilitating the discharge of the mixture. The discharge pipe 15 is connected to the first opening to form a fluid channel, which can effectively guide the mixture out of the fermentation tank 1. And a piston block is provided inside the discharge pipe 15 for isolating the mixture, that is, when a reaction occurs, the piston block is inserted into the discharge pipe 15 to prevent the mixture from flowing out. When the mixture is to be discharged after the reaction is completed, the piston block can be removed.

[0046] The fermentation tank 1, as a microbial reaction device, is used to hold the mixture of plant residues and soil and provide suitable environmental conditions to promote the anabolic reactions of microorganisms.

The inoculant applicator 4 is used to add a specific carbon-fixing microbial inoculant, namely, a mixed inoculant of nitrogen-fixing bacteria and arbuscular mycorrhizal fungi, to enhance the biological activity of the soil and improve the carbon-fixing effect. The water adder 5 can manually add an appropriate amount of water according to the moisture requirement of the soil to maintain the appropriate humidity of the mixture. The moisture meter 6 monitors the humidity of the mixture inside the fermentation tank 1 in real time and provides data support for the operation of the water adder 5; the thermometer 7 is used to monitor the temperature status in the fermentation tank 1 in real time, facilitating linkage with the temperature control component 3 to achieve autonomous regulation.
