Description

Technical Field

[0001] The utility model relates to the field of soil sampling, and in particular to a sampling device that can be used to detect phosphorus components in soils at different depths. Background Art

[0002] With the development of precision agriculture, accurate detection of various nutrients in the soil has become increasingly important. An appropriate amount of phosphorus content is beneficial to crop growth and development, and can improve crop quality and yield. Phosphorus is related to plant energy biochemical reactions and relies on the role of phosphoric acid in many enzyme metabolisms. At the same time, phosphorus is also a component of biological genetic material-nucleic acid. It has a very important relationship with cell division and the development of meristems, and is one of the indispensable macroelements for plant growth and development.

[0003] Existing soil sampling methods usually use manual operations. When using tools to sample the soil manually, it is difficult to sample soil at different depths. In addition, when sampling manually, there is no support mechanism, and the operational stability of sampling tools (such as shovels, drill bits, etc.) in the soil will be greatly reduced, which may lead to inaccurate sampling positions and difficult to control depths. Therefore, we have made improvements on this and proposed a sampling device that can be used to detect the phosphorus composition of soil at different depths. Utility Model Content
