[0024] (III) Beneficial effects

[0025] Compared with the prior art, the present invention provides a soil-fixing and water-locking method based on the growth of Gobi green plants and its application, which has the following beneficial effects:

[0026] 1. The soil-fixing and water-locking method and application based on the growth of green plants in the Gobi Desert. The soil-fixing and water-locking device absorbs moisture from the air through hygroscopic action at night, and reduces water evaporation when the temperature rises during the day, thereby increasing soil moisture and improving soil moisture retention capacity. The physical properties of plant straw materials promote the formation of a soil moisture-retaining microenvironment. The soil-fixing and water-locking device composed of plant straw materials can capture and store grass seeds moved by wind and sand, thereby promoting the natural reproduction of local plants, which helps to accelerate the recovery of vegetation in the Gobi Desert and enhance the stability of the ecosystem.

[0027] 2. The soil-fixing and water-locking method and application based on the growth of green plants in the Gobi Desert. The application of the sensor array provides a real-time monitoring method for the effectiveness of the soil-fixing and water-locking device. The soil moisture sensor and the soil temperature sensor collect soil data at regular intervals and transmit them to the data acquisition unit through the wireless communication module. The data acquisition unit further processes the data and displays it through the remote monitoring platform. This can not only evaluate the working condition of the soil-fixing and water-locking device in real time, but also adjust the layout of the device or improve the design according to the collected data, thereby optimizing the performance of the entire soil-fixing and water-locking system. This dynamic feedback mechanism ensures that the soil-fixing and water-locking method can continue to function under constantly changing natural conditions.

[0028] 3. The soil-fixing and water-locking method and application based on the growth of green plants in the Gobi Desert. The soil-fixing and water-locking device has the function of locally retaining moisture and soil, especially when local rainfall sometimes occurs in the Gobi Desert, it can play a significant role in soil and water conservation. Moreover, the soil-fixing and water-locking device mainly utilizes rod-shaped organic waste (such as corn stalks, sunflower stalks, etc.) for slit-arranged covering, in which the gaps account for 20% of the covering area. This method not only makes full use of the resources of discarded crops, but also facilitates air circulation due to the presence of gaps. At the same time, the design of the soil-fixing and water-locking device is not limited to the use of corn stalks or other single crop stalks. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the embodiments of the present invention and the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1-2 , a soil-fixing and water-locking method based on the growth of Gobi green plants, comprising the following steps:

[0034] S1, selecting plant straw as the basic material of the soil-fixing and water-locking structure, processing the plant straw into a rod-shaped structure, and then connecting and fixing the plant straw in the rod-shaped structure to form a soil-fixing and water-locking device;

[0035] S2. Arrange soil-fixing and water-locking devices at predetermined intervals in the Gobi region;

[0036] S3. Use soil-fixing and water-locking devices to improve the local microenvironment, increase soil moisture by absorbing moisture at night and retaining water during the day, and improve soil moisture retention capacity;

[0037] S4. Capture and preserve grass seeds in the wind-blown sand through soil-fixing and water-locking devices to promote natural plant reproduction;

[0038] S5. Collect soil temperature and humidity data in real time through the sensor array to evaluate the effectiveness of the device.

[0039] The invention discloses an application of a soil-fixing and water-locking method based on the growth of green plants in the Gobi Desert. The soil-fixing and water-locking method based on the growth of green plants in the Gobi Desert is applied to soil improvement and vegetation restoration projects in arid and semi-arid areas.

[0040] Specifically, plant straws such as corn stalks or rice straws are selected as the base material because these materials are naturally degradable and low-cost. They are processed into rod-like structures of specific sizes (30-50 cm in length and 5-10 cm in diameter) and then interconnected to form a soil-fixing and water-locking device. This not only utilizes waste crop resources, but also plays a role in fixing soil and locking water.

[0041] Specifically, at night, the temperature in the Gobi region drops and the relative humidity in the air is usually high. At this time, the plant straw material in the soil-fixing and water-locking device will absorb moisture in the air. The plant straw has a certain hydrophilicity and can absorb and retain more moisture.

[0042] Specifically, as the day progresses, the temperature rises, which usually causes water to evaporate quickly. However, the structural design and material properties inside the soil-fixing and water-locking device enable it to slow down the evaporation rate of water. The pore structure inside the plant straw material can, to a certain extent, prevent water from directly contacting high-temperature air, thereby reducing water loss.

[0043] Experimental Example 1:

[0044] Evaluate the impact of soil-fixing and water-locking devices on surface temperature and humidity at different times

[0045] Material: Soil-fixing and water-locking device made of plant straw

[0046] Table 1 Record of temperature and humidity changes at various locations of soil-fixing and water-locking device under different time conditions:

[0047]

[0048] After a week of continuous temperature and humidity testing, it was found that when the external temperature is high, the temperature of the plant roots under this device is low, and when the external temperature is high, this device can ensure that the temperature of the plant roots below is low. When the external environment is relatively dry, the humidity below this device is high, and when the external environment is relatively humid, this device can better retain moisture. This device can always maintain a temperature and humidity close to that which is conducive to crop growth;

[0049] In general, the soil-fixing and water-locking device showed positive effects in increasing soil moisture, reducing water evaporation and improving surface temperature, which helps to create a microenvironment more suitable for plant growth and promote the recovery of vegetation in the Gobi region. This conclusion emphasizes the potential application value of the soil-fixing and water-locking device in soil improvement and vegetation restoration projects in arid and semi-arid areas.

[0050] Experimental Example 2:

[0058] (5) Record humidity values ​​every day and observe the growth of the woody plant seedlings;

[0066] Experimental methods:

[0067] (1) Prepare four containers of the same size and fill them with the same amount of the same type of soil;

[0068] (2) Two of the containers were installed with soil-fixing and water-locking devices, and the other two containers were used as a control group without any devices installed;

[0069] (3) Plant the same number of woodleaf thorn seeds in each container;

[0071] (5) Record the temperature every day and observe the growth of the woody plant seedlings;

[0072] (6) Maintain the experimental period for one month and keep the humidity constant during this period.

[0074]

[0075] Conclusion: The survival rate of the woody plant seedlings in the experimental group using the soil-fixing and water-locking device was higher than that of the corresponding control group under all temperature conditions. Especially under low and high temperature conditions, the soil-fixing and water-locking device could better demonstrate its advantages, improve the plant survival rate, and the soil moisture was also significantly improved.

[0076] In summary, the soil-fixing and water-locking method and application based on the growth of green plants in the Gobi Desert, the soil-fixing and water-locking device absorbs moisture from the air through hygroscopic action at night, and reduces water evaporation when the temperature rises during the day, thereby increasing soil moisture and improving soil moisture retention capacity.

This method not only makes full use of the resources of discarded crops, but also contributes to air circulation due to the presence of gaps. At the same time, the design of the soil-fixing and water-locking device is not limited to the use of corn stalks or other single crop stalks.

[0078] Moreover, in the soil-fixing and water-locking method and application based on the growth of green plants in the Gobi Desert, the application of the sensor array provides a means of real-time monitoring of the effectiveness of the soil-fixing and water-locking device; the soil moisture sensor and the soil temperature sensor collect soil data at regular intervals and transmit them to the data acquisition unit through the wireless communication module; the data acquisition unit further processes the data and displays it through the remote monitoring platform; in this way, not only can the working condition of the soil-fixing and water-locking device be evaluated in real time, but the layout of the device can also be adjusted or the design can be improved according to the collected data, thereby optimizing the performance of the entire soil-fixing and water-locking system.
