Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a labor-saving device for sampling deep soil in saline-alkali land. Background Technique

[0002] At present, saline-alkali land refers to a kind of soil in which the salt content in the soil affects the normal growth of crops. In severely saline-alkali soil areas, plants can hardly survive. The poor physical and biological properties of saline-alkali soil make the soil wet, sticky, dry and hard, with poor water permeability and air permeability. This also makes it more difficult to conduct soil sampling in saline-alkali land compared with other soil types (such as black soil, sandy soil, etc.). During the soil sampling process, it is also difficult to press the soil drill down to the deep layer of the soil and then take it out. Moreover, the deeper the drill goes, the greater the resistance between the soil drill and the soil on the side wall of the sampling hole, and the more laborious it is to take out, which brings great difficulties to the sampling work of the saline-alkali land soil sampling device. Therefore, a labor-saving device for sampling deep soil in saline-alkali land is proposed here. Content of the Utility Model
