As a core component of soil information, soil mechanical properties have important guiding significance for regulating soil environment, optimizing cultivation tools and cultivation methods. However, the soil information library has problems such as large number of soil samples, large difference in soil properties, and small amount of soil available for detection, making it difficult to efficiently and accurately obtain effective soil information, especially for soil mechanical properties with a large number of parameters.
