This invention provides a method and apparatus for collecting earthworm burrow wall soil. The method includes collecting raw soil, adjusting the particle composition of the raw soil to obtain culture soil. A mesh screen is laid in a culture pot, and the culture soil is placed inside the mesh screen. Earthworms are placed in the culture soil, and the culture pot is placed in an incubator. The environmental parameters in the incubator are adjusted to allow the earthworms to construct burrows within the culture soil. A preset time is checked; if so, the culture soil is removed, and the burrow wall soil is peeled off. The culture soil balances plasticity and permeability to meet the needs of earthworm growth and burrow building during long-term cultivation. By adjusting the temperature, humidity, and light intensity in the incubator, the earthworms can fully construct burrows while maintaining stable burrow wall soil properties. A hard, pointed spoon is used to precisely peel off the burrow wall soil, ensuring that the burrow wall soil sample is free from cross-contamination and structurally intact.

A grassland rodent burrow identification method based on UAV aerial photography and machine learning is proposed. First, a UAV is used to photograph the survey area to obtain high- and low-altitude images. Then, the high-altitude images are pre-processed using the coordinates of ground control points to obtain the corresponding DOM (Domain Image) images. Next, both the DOM and low-altitude images undergo color space transformation and multi-scale segmentation to obtain corresponding high- and low-altitude polygon images. The low-altitude polygon images are then divided into training and validation samples. The algorithm classifier is repeatedly trained and validated using these samples until the required accuracy is achieved, resulting in a mature algorithm classifier. Finally, the high-altitude polygon images are fed into the algorithm classifier to output the vector data of the rodent burrow polygons. This design not only offers good accuracy and low time consumption but also boasts high recognition speed and strong timeliness, making it suitable for precise dynamic monitoring and prediction of rodent distribution.
