[0062] This embodiment also provides a method for using the desert irrigation-free greening device 100, comprising the following steps:

[0063] Step 1: Prepare the planting box 1. First, ensure that the water collection mechanism 2, water storage container, windbreak 5 and support components are installed. Fill the planting box 1 with soil 8, lay a covering layer 9 on the top of the planting box 1, and plant the selected plants in the soil 8 so that the roots of the plants pass through the through holes on the support component into the liquid supply cavity 7 to directly absorb water. The water storage container and the planting box 1 are buried in the selected area in the desert. The plants in this embodiment are drought-tolerant plants.

[0064] Step 2: Collect water from nature through the water collection mechanism 2 and transport the water to a water storage container.

[0065] Specifically, rainwater is collected by the collecting hopper 201, and water vapor in the air is collected by the condensation water collecting sheet 202.

The liquid level sensor 208 detects the water amount in the water storage chamber 207. When it is detected that the water amount in the water storage chamber 207 reaches a certain level, the controller 16 controls the solenoid valve 209 to open, allowing water to flow into the water storage tank 3.

[0066] Step 3: The soil moisture sensor 10 monitors the moisture of the soil 8 and transmits the data to the controller 16 . When the moisture value of the soil 8 is lower than a preset value, the controller 16 controls the pumping mechanism to pump the water in the water storage container to the liquid supply chamber 7 .

[0067] Specifically, the controller 16 decides whether to start the water pump 13 for watering based on the information provided by the soil moisture sensor 10. When the moisture of the soil 8 is lower than the preset value, the controller 16 will start the water pump 13, extract the stored water from the water tank 3 through the suction pipe 14, and directly supply it to the liquid supply cavity 7 where the plant roots are located through the water outlet nozzle 15.

[0068] The device is maintained and monitored during use. Specifically, the working status of system components is regularly checked, including cleaning or replacing the filter layer, monitoring soil 8 moisture, and evaluating plant growth conditions, to ensure the continued effective operation of the system.

[0069] The desert irrigation-free greening device 100 in this embodiment uses renewable resources such as rainwater and water vapor in the air as the main water source, and achieves the survival and growth of vegetation under extreme drought conditions through water capture, water preservation and system self-maintenance, without the need for artificial irrigation, reducing the dependence on groundwater or long-distance water delivery, and promoting environmental protection and sustainable development. Due to the high degree of automation, the need for manual intervention is reduced, and the maintenance cost can be greatly reduced in the long run. At the same time, operations such as regular inspection and cleaning of filters are also relatively simple and easy.

[0070] The desert irrigation-free greening device 100 in this embodiment closely combines multiple links from water collection, water storage, water supply to wind protection, forming an efficient and self-sufficient ecosystem, aiming to solve key problems encountered in the process of vegetation restoration in desertified areas, such as water shortage, adverse climatic conditions, etc. The desert irrigation-free greening device 100 in this embodiment can be applied to the periphery of desert roads and desert railways, and can curb desert expansion through vegetation restoration, and reduce the risk of desert roads and desert railways being buried by wind and sand. At the same time, the device is not only suitable for greening along desert roads and desert railways, but can also be promoted and applied to ecological restoration projects in other arid and semi-arid areas, which is of great significance for improving the local ecological environment.
