[0028] Example 1

[0029] As Figure 1 - Figure 2 shown, in this embodiment, a drip irrigation system for integrated water and fertilizer of traditional Chinese medicine materials is provided, including: a control unit, a user terminal 17, a reservoir 1, a power supply device 2, a fertilization device, a filtering device 8 and a main pipeline network 10; the reservoir 1 is arranged on the mountain, the power supply device 2 is arranged above the reservoir 1, and the reservoir 1 is connected to the feeding end of the fertilization device through a connecting pipeline; the discharging end of the fertilization device is connected with a filtering device 8, the filtering device 8 is connected to the main pipeline network 10 through an electromagnetic valve 14, a plurality of branch pipelines are arranged on the main pipeline network 10, each branch pipeline is laid along the ground of the corresponding cultivation area, traditional Chinese medicine materials are planted in the cultivation area, and a plurality of water sensors 15 are arranged in the cultivation area; a plurality of ball valves 12 are arranged on each branch pipeline, and the ball valves 12 on the same branch pipeline are arranged in sequence at a preset interval, the preset interval is determined according to a preset drop threshold, and a plurality of drip irrigation tapes 13 are also arranged on each branch pipeline;

[0030] The control unit includes a main controller 16, the main controller 16 is communicatively connected with the user terminal 17, and the electromagnetic valve 14, the power supply device 2 and each water sensor 15 are electrically connected to the main controller 16.

[0031] Most of the current drip irrigation with integrated water and fertilizer is used in flat areas such as large fields or fruits and vegetables. This embodiment can be used in areas with a drop such as mountainous and hilly areas. When the main pipeline network 10 is laid in mountainous and hilly areas, a ball valve 12 should be added when the drop is 4 meters to ensure the same pressure in the upper and lower pipelines; during the laying process of the drip irrigation tape 13, it should be laid at a slope of less than 20 degrees, and the length is between 50-70 meters according to the slope size.

[0032] In this embodiment, first, a reservoir 1 is dug according to the irrigation area and water consumption to collect surface water (mainly including rainwater and surface runoff); second, a photovoltaic panel is installed on the reservoir 1 to store electricity through independent photovoltaic power generation; then, the stored electricity is used to drive a water pump to pump water, and the water flows through the integrated water and fertilizer equipment and the drip irrigation equipment to slowly drip the water and fertilizer around the crop roots. This embodiment can increase the yield per mu of traditional Chinese medicine materials planted in mountainous and hilly areas by 10%-15%, improve the fertilizer utilization rate by 20%, increase the water resource utilization rate by 30%, and increase the mu income by more than 10%.

[0033] The specific implementation steps of this embodiment include:

[0034] Water source: The drip irrigation water source mainly comes from surface water and can also be groundwater. For the surface water source, according to the terrain, pits are dug on the land with a slope of less than 20 degrees to intercept and store water.

[0035] Pump and power: According to the irrigation area and water delivery distance, select the corresponding pump and supporting power. For surface water, it is recommended to choose a centrifugal pump, and for groundwater, it is recommended to choose a submersible pump, and install a solenoid valve 14.

[0036] Filtration system: According to the water quality condition and the sediment content, select the corresponding filter. When the sediment content is small, it is recommended to choose a mesh filter; when the sediment content is large, it is recommended to choose a centrifugal filter + mesh filter.

[0037] Fertilization system: A fertilizer tank 7 should be installed at the front end of the filter, and an anti-backflow device 6 should be installed at the front end of the fertilization system to prevent fertilizer from flowing back and polluting the water source. For mountainous and hilly areas mainly composed of terraced fields or sloping fields, it is recommended to use a small fertilizer tank 7 to meet the fertilization requirements.

[0038] Main pipeline 10 laying: According to the water supply capacity of the pump and the irrigation area, select a composite water hose or PE pipe of the corresponding size, and install a solenoid valve 14.

[0039] When laying the main pipeline 10, it should be reasonably laid according to the topographical features of mountainous and hilly areas to ensure that the pressure error before and after the main pipeline is within 5%.

[0040] Branch pipeline 11 laying: In mountainous and hilly areas, PE flexible hoses or plastic-coated hoses are preferably used for straight pipes. They are laid on the ground and perpendicular to the Chinese herbal medicine planting. And a ball valve 12 needs to be installed every 4 meters of elevation difference to facilitate the control of the upper and lower pressures of the branch pipeline.

[0041] Laying of capillary tubes (drip irrigation tapes 13): In mountainous and hilly areas, it is advisable to use patch-type, low-flow, and widely spaced drip irrigation tapes 13. The laying length of the drip irrigation tape 13 is proportional to the water pressure and inversely proportional to the terrain and slope (less than 20 degrees). The recommended length is 50m - 70m for the best effect. Through the precise drip irrigation method, water and nutrients are directly delivered to the roots of Chinese herbal medicines, reducing water evaporation and nutrient loss, improving the utilization rate of water and fertilizers. This not only saves precious water resources but also reduces the use of chemical fertilizers and agricultural non-point source pollution.

[0042] Construction of reservoir 1: According to the water consumption of 3 - 5 cubic meters per mu per irrigation (or according to the actual situation in mountainous areas), reasonably construct the reservoir 1, and set up a protective net around it and cover it with photovoltaic panels to eliminate potential hazards.

[0043] Construction of photovoltaic power station: According to the power consumption requirements of the pump and the field control system, reasonably install photovoltaic panels and build relevant boxes to accommodate batteries and accessories. The system uses photovoltaic power generation to provide power for the pump and control system, realizing the application of green energy. This not only reduces the dependence on traditional energy but also reduces carbon emissions, meeting the requirements of environmental protection and sustainable development.

[0044] Irrigation data collection system: It consists of a pipeline flowmeter 5, a pressure gauge 9, and a soil moisture sensor 15. According to relevant regulations, an unequal number of moisture sensors 15 are installed in the field (3 monitoring points are installed in each irrigation unit, and the soil water content of the 10 cm and 20 cm soil layers is measured at each monitoring point) to understand the soil conditions, and the irrigation water volume is statistically calculated in real time, the working pressure of the detection system, and the water volume and pressure data of each irrigation unit are detected.

[0045] Internet of Things system: It is connected to a storage battery and consists of hardware such as a main controller 16, a communication control (acquisition) device, a local communication control (acquisition) device, an antenna, a repeater, etc. The information collected can be displayed on the client side, and the client side includes mobile phones, computers, or other electronic devices. The communication device includes one or more of a LoRa module, a 2.5G communication module, a 3G communication module, a 4G communication module, and a 5G communication module.

[0046] By monitoring the soil conditions and converting them into electrical signals or other required forms of information for output, the solenoid valve 14 can be remotely controlled through a mobile phone or other electronic devices to control the water output. When dripping water and fertilizer, it should be operated in the steps of first dripping clear water to moisten the soil surface, then dripping fertilizer, and finally dripping clear water again.

[0047] The introduction of the Internet of Things system has realized the intelligent management of the irrigation process. By real-time monitoring of parameters such as soil moisture, flow rate, and pressure, the system can automatically adjust the irrigation plan to ensure that the Chinese medicinal materials obtain the most suitable irrigation conditions. At the same time, users can also remotely control the solenoid valve 14 and the fertilization system through electronic devices such as mobile phones or computers to achieve precise irrigation and fertilization.

[0048] As described above, it is only the preferred specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the technical field of this application within the technical scope disclosed by this application should be covered by the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
