This invention discloses a sand-fixing method utilizing coppicing and sand burial of Haloxylon ammodendron, relating to the fields of windbreak, sand fixation, and vegetation restoration. Based on the natural growth angle of Haloxylon ammodendron branches, this invention applies coppicing and layering treatments to upright and inclined branches respectively. Inclined branches are laid flat against the ground and buried in sand, causing adventitious roots to sprout from the buried internodes and new suckers to grow upwards. These newly formed suckers are guided towards adjacent plants and buried perpendicular to the prevailing wind direction, creating a connected network structure between plants through their root systems and stolons. This invention classifies and treats branches according to their type. Coppicing upright branches reduces plant height and branch height, promoting tillering; sand burial of inclined branches induces adventitious roots, expands the water absorption area, lowers the center of gravity of branches and leaves, and increases ground cover, which is beneficial for improving the sand-fixing efficiency of vegetation, enhancing the water use efficiency of Haloxylon ammodendron, and promoting healthy shrub development.

This invention relates to the field of temperature sensor testing, specifically the application of testing and measurement technology in the control of microclimates in aquaculture. The method involves deploying a sealed reference cavity with a built-in standard thermometer in a forest-based aquaculture area. Each temperature sensor node is periodically inserted into the reference cavity to periodically read the current temperature value and compare it with the standard thermometer to obtain the absolute drift. A two-dimensional drift matrix is ​​constructed by combining this data with historical humidity data of the location. During non-calibration periods, the original temperature values ​​are corrected using the two-dimensional drift matrix. The corrected temperature values ​​are then used in a Kriging space interpolation algorithm to generate a three-dimensional temperature field distribution map. Based on the coordinates of local high-temperature areas in the distribution map, the corresponding spray cooling solenoid valves are activated. This invention offsets the long-term drift caused by the high-humidity and corrosive environment of the forest undergrowth, corrects the spatial deviation of the original temperature data, improves the accuracy of the three-dimensional temperature field reconstruction, and avoids control misalignment caused by temperature field assessment distortion.
