Description

Technical Field

[0001] The utility model relates to the technical field of leaching simulation experiments, in particular to a soil leaching simulation experiment device. Background Art

[0002] Leaching refers to a soil process in which soluble or suspended compounds in soil materials (clay, organic matter, soluble salts, carbonates and iron and aluminum oxides, etc.) migrate from the upper part of the soil to the lower part, or migrate laterally under the action of water movement. This process is common in soil. Leaching includes leaching, chelation leaching and mechanical leaching. During the leaching process, soil materials may undergo dissolution, chemical extraction, chelation and mechanical leaching. Leaching leads to the loss of materials in the upper part of the soil and the formation of a leaching layer. Soil materials leached from the upper to the lower layers of the soil profile often settle in the lower layers to form various sedimentation layers. Leaching can also cause certain soil materials to be completely lost from the soil profile through groundwater and other channels.

[0003] However, after the soil leaching experiment, when sampling is required at different locations of the experimental soil, the entire soil needs to be poured out from the inside of the leaching column. This operation process can easily lead to damage to the soil structure. Utility Model Content
