Description

Technical Field

[0001] The invention relates to the technical field of soil detection, and in particular to a device for quantitatively analyzing salt content in a salinized soil profile. Background Art

[0002] Soil profile refers to a vertical section exposed by digging from the ground, with a depth generally within two meters. It is an important concept in soil science and is used to observe and study the morphological characteristics of soil. A salinized soil profile salt quantitative analysis device usually refers to an instrument or system that can accurately measure and analyze the salt content and its distribution pattern in the soil profile. Such devices have important application value in agriculture, environmental science, soil science and other fields, especially in arid and semi-arid areas, where soil salinization is particularly prominent. Therefore, quantitative analysis of soil salt is particularly important.

[0003] Most devices in the prior art take out samples from the sampler at the same time, and the taking-out method is generally through pushing.
