[0020] To make the above-mentioned objects, features and advantages of the present invention more readily understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0023] Please see Figures 1-7 ; in Figure 7 Curves 1, 2, and 3, from top to bottom, represent the relevant elements after treatment of cow dung waste, greenhouse waste, and straw waste, respectively. Curve 4 represents the compound components such as silicon dioxide, iron oxide, strontium oxide, and zirconium oxide. This embodiment provides an agricultural water-saving irrigation device based on terahertz materials, including: a main irrigation pipeline 1, a terahertz treatment section 2, a temperature control component 3, a connecting flange 4, irrigation branch pipelines 5, and drip cans 6; The connecting flange 4 is fixedly installed at one end of the irrigation main pipeline 1, and the terahertz treatment section 2 is fixedly installed at one end of the connecting flange 4. The terahertz treatment section 2 is equipped with a temperature control component 3. Irrigation branch pipe 5 is located at one end of terahertz treatment section 2, and drip can 6 is fixedly installed at one end of irrigation branch pipe 5.

[0024] Furthermore, drip irrigation heads 6 or micro-sprinkler heads are installed at the end of the irrigation branch pipe 5. The diameter of the irrigation branch pipe 5 is 20mm. The drip irrigation heads 6 or micro-sprinkler heads installed at its end are evenly distributed around the crop roots with a spacing of 30cm, so that the depolymerized small molecule water can be accurately delivered to the crop roots, further improving absorption efficiency and reducing water waste.

[0025] Temperature control component 3 is connected to terahertz material layer 22 to stabilize the temperature of terahertz material layer 22 at 45-55℃. When irrigation water passes through terahertz treatment section 2, it is affected by terahertz waves radiated by terahertz material layer 22, causing water molecule aggregates to depolymerize into dispersed small molecule water.

[0026] For example, the terahertz processing section 2 includes an inner input pipe 21, a terahertz material layer 22, an insulation layer 23, and an outer water supply pipe 24. The terahertz material layer 22 is disposed on the surface of the inner input pipe 21, the insulation layer 23 is disposed on the surface of the terahertz material layer 22, and the outer protective pipe 24 is disposed on the surface of the insulation layer 23.

[0027] Furthermore, the inner water pipe 21 is made of polytetrafluoroethylene, with a diameter of 50 mm and a wall thickness of 3 mm. It has good corrosion resistance and wave transmission, and does not affect the penetration and transmission of terahertz waves. The outer wall of the inner water pipe 21 is tightly attached to the terahertz material layer 22. The terahertz material layer 22 is made of polyimide composite material doped with zinc oxide, with a thickness of 1 mm. This material can stably radiate terahertz waves of 0.1 to 10 THz in the temperature range of 45℃ to 55℃. It can resonate and couple with the vibration mode of water molecules, effectively destroy the hydrogen bond connection between water molecules, and realize the deagglomeration of aggregates.

[0028] The terahertz material layer 22 is wrapped with an insulation layer 23. The insulation layer 23 is made of rock wool insulation material with a thickness of 4mm, which can effectively reduce the heat loss of the terahertz material layer 22 and ensure the stability of temperature control.

[0029] An outer water pipe 24 is installed on the outside of the insulation layer 23. The outer water pipe 24 is made of PVC rigid plastic, with a diameter of 60mm and a wall thickness of 4mm. It has the characteristics of impact resistance, aging resistance and waterproofing, and is used to protect the internal structure from damage by the external environment.

[0030] For example, the terahertz material layer 22 is an inorganic material obtained by low-temperature radiation thermal decomposition of straw, and the thickness of the terahertz material layer 22 is 0.1 mm to 2 mm.

[0031] Further, after the crop straw is decomposed by radiative heat, strontium and zirconium are leached out with dilute acid to obtain a first leachate. A second leachate containing manganese, cobalt, and molybdenum is obtained from non-straw agricultural waste such as livestock manure and bagasse through hydrothermal extraction. The two leachates are mixed to obtain a composite precursor solution. Unpyrolyzed straw is crushed and immersed in this composite precursor solution. Under hydrothermal conditions, the straw fibers fully adsorb and chelate the aforementioned metal ions. After removal, it is first carbonized at low temperature in an inert atmosphere to form a porous carbon framework, and then heated to allow the adsorbed metal ions to be converted in situ into strontium molybdate, zirconium-doped oxides, and manganese-cobalt-molybdenum oxides within the carbon framework pores, forming a composite powder with abundant heterogeneous interfaces. This powder is then processed into a thin film with a thickness of 0.1 mm to 2 mm by casting and spraying. After drying, the terahertz material layer 22 is obtained. The terahertz material layer 22 can stably radiate broadband terahertz waves of 0.1 to 10 THz without an external excitation source at a mild temperature of 48℃ to 52℃, which can be used to depolymerize water molecule aggregates in irrigation water and form dispersed small molecule water.

[0032] For example, the inner water pipe 21 is made of polytetrafluoroethylene, the outer water pipe 24 is made of rigid PVC plastic, and the insulation layer 23 is made of rock wool insulation material. The thickness of the inner water pipe 21, the outer water pipe 24 and the insulation layer 23 are all 3mm to 5mm.

[0033] For example, the connecting flange 4 is made of stainless steel, and a nitrile rubber sealing gasket is provided on the inner side of the connecting flange 4.

[0034] Furthermore, the irrigation main pipeline 1 and irrigation branch pipeline 5 are connected by two connecting flanges 4, and the connection is sealed by the connecting flanges 4 to prevent leakage of irrigation water.

[0035] For example, the temperature control component 3 includes a temperature sensor 31, a heating wire 32, a temperature controller 33, and a power supply module 34. The temperature sensor 31 is fixedly installed inside the terahertz processing section 2, the heating wire 32 is fixedly installed inside the terahertz processing section 2, and the temperature controller 33 is electrically connected to the temperature sensor 31, the heating wire 32, and the power supply module 34 respectively.

[0036] Furthermore, the temperature control component 3 is connected to the terahertz material layer 22 to stably control the temperature of the terahertz material layer 22 at around 50°C.

[0037] The temperature controller 33 is a digital display temperature controller, model XMTD-7000, which is electrically connected to the temperature sensor 31, the heating wire 32 and the power supply module 34 respectively. It receives the temperature data from the temperature sensor 31. When the temperature of the terahertz material layer 22 is lower than 48°C, it controls the heating wire 32 to start heating. When the temperature is higher than 52°C, it controls the heating wire 32 to stop heating, so as to ensure that the temperature of the terahertz material layer 22 is stable within the target range.

[0038] For example, the heating wire 32 is made of carbon crystal material and is attached between the terahertz material layer 22 and the insulation layer 23.

[0039] Furthermore, the heating wire 32 is made of carbon crystal material, which is formed by high-temperature sintering of 92% to 96% alumina and 4% to 8% sintering aids. The metal heating resistor paste is printed on the carbon crystal material according to the heating circuit design requirements.

[0040] The heating wire 32 has dimensions of 5cm×5cm×17mm, a dielectric constant of 9.8, and a resistivity of approximately 1kΩ·cm. It is evenly distributed around the circumference of the terahertz treatment section 2 to ensure uniform heating.

[0041] For example, temperature sensor 31 is embedded inside terahertz material layer 22.

[0042] Furthermore, the temperature sensor 31 is embedded inside the terahertz material layer 22, employing a PT100 temperature sensor, which can acquire the temperature data of the terahertz material layer 22 in real time with a measurement accuracy of ±0.5℃. For example, the power supply module 34 is a solar power supply module, which includes a solar panel and an energy storage battery.

[0043] Furthermore, the power supply module 34 can also supply power to the temperature control component 3 via the mains power supply module.

[0044] The power supply module 34 adopts a solar power supply module, including a 100W solar panel and a 12V energy storage battery. It is suitable for outdoor farmland scenarios without mains power supply, and is energy-saving and environmentally friendly. It can also be replaced with a mains power supply module according to actual needs.

[0045] Significant water-saving effect: The terahertz waves radiated by the terahertz material layer of the terahertz treatment section 2 can efficiently deagglomerate water molecule clusters in irrigation water, forming dispersed small molecule water. Small molecule water has stronger permeability and can quickly penetrate into the deep soil layers and be absorbed by crop roots, effectively reducing surface water evaporation and deep seepage. Experiments have verified that this device can increase the utilization rate of irrigation water resources by more than 10%, significantly reducing water waste.

[0046] Precise temperature control: The temperature control component 3 can stably control the temperature of the terahertz material layer at around 50°C. This temperature range allows the terahertz material to stably radiate terahertz waves, avoiding excessively high or low temperatures that could affect the radiation effect of terahertz waves. This ensures the stability and efficiency of water molecule depolymerization, while the insulation layer reduces heat loss and lowers energy consumption.

[0047] Simple structure and strong adaptability: The device has a compact overall structure. The terahertz processing section 2 can be quickly connected to the existing irrigation pipeline through the connecting flange, without the need for large-scale modification of the existing irrigation system. It is compatible with various irrigation modes such as drip irrigation and micro-sprinkler irrigation, and can be widely used in various agricultural planting scenarios such as field crops, facility vegetables, and fruit trees.

[0048] Long service life: The inner water supply pipe of the terahertz treatment section 2 is made of corrosion-resistant and wave-transparent material, the outer water supply pipe 24 is made of impact-resistant and anti-aging material, and the heating wire is made of carbon crystal material. All components are adapted to the complex environment of agricultural irrigation, effectively extending the service life of the device and reducing the cost of use.

[0049] Green and environmentally friendly with low energy consumption: Terahertz waves depolymerize water molecules without chemical additives, and will not pollute soil, crops and water resources, which meets the needs of green agricultural development; at the same time, the insulation layer is set up.

[0050] In use, the terahertz treatment section 2 is connected to the main irrigation pipeline 1 and the irrigation branch pipeline 5 through two connecting flanges 4, ensuring good sealing. The temperature sensor 31 of the temperature control component 3 is embedded in the terahertz material layer 22, and the heating wire 32 is attached between the terahertz material layer 22 and the insulation layer 23. The temperature controller 33 and the power supply module 34 are connected to complete the installation of the device.

[0051] By activating the temperature controller 33, the target temperature of the terahertz material layer 22 is set to 50°C. The temperature controller 33 receives the temperature data collected by the temperature sensor 31 and controls the heating wire 32 to start heating. When the temperature of the terahertz material layer 22 reaches 50°C, the heating wire 32 stops heating, and the insulation layer 23 reduces heat loss, ensuring that the temperature is stable within the range of 48°C to 52°C.

[0052] When irrigation is carried out, the irrigation system is first started. Irrigation water flows from the main irrigation pipe 1 into the inner water delivery pipe 21 of the terahertz treatment section 2. When passing through the terahertz material layer 22, the terahertz material layer 22 stably radiates terahertz waves at a temperature of about 50°C. The terahertz waves penetrate the inner water delivery pipe 21 and act on the irrigation water, generating resonant coupling with the vibration mode of water molecules, breaking the hydrogen bond connection between water molecules, and causing the aggregated water molecules to depolymerize into dispersed small water molecules. The depolymerized small water molecules are transported to the drip irrigation head 6 through the irrigation branch pipe 5. The drip irrigation head 6 accurately drips water around the crop roots. The small water molecules quickly penetrate into the deep soil and are efficiently absorbed by the crop roots, realizing water-saving irrigation. This improves the utilization rate of irrigation water resources by more than 10% and the water absorption efficiency of crop roots by more than 10%. At the same time, it reduces the evaporation of surface soil moisture and deep seepage, greatly reducing water waste. It is suitable for water-saving irrigation in various agricultural planting scenarios.

[0053] In summary, the terahertz waves radiated by the temperature-controlled terahertz material layer 22 through the terahertz treatment section 2 can efficiently deagglomerate water molecule clusters in irrigation water, forming dispersed small molecule water. Small molecule water has stronger permeability and can quickly penetrate into the deep soil layers and be absorbed by crop roots, effectively reducing surface water evaporation and deep seepage.
