Surface soil sampler fast and convenient to use

Abstract

The invention discloses a surface soil sampler fast and convenient to use. The sampler comprises a handle and a sampling head which are connected with each other. The sampling head comprises a top plate and a bottom plate which are stacked in a spaced mode. A closed structure is arranged on the side, close to the handle, between the top plate and the bottom plate, and other portions are open. The surface soil sampler is simple in structure and can be used for horizontal sampling and vertical sampling, and errors of samples are reduced; samples in the soil sampler do not need to be collected by hand, and thus the surface soil sampler is fast and convenient to use, and labor is saved. When the vertical sampling mode is selected, the sampling amount is large, and damage to the soil layer structure of facility soil and the roots of plants is small; when the horizontal sampling mode is selected, soil of a specified layer can be collected, and the section characteristics of soil samples are perfectively preserved. A worker can select different sampling modes according to requirements or specific environments.

Description

technical field [0001] The invention relates to a soil sampling device, in particular to a portable surface soil sampler. Background technique [0002] The collection of soil samples is the prerequisite for the evaluation and analysis of soil nutrients and pollution levels in the field of agricultural resource utilization and environmental science, and is one of the important basic tasks for scientific and technological workers engaged in soil research. Whether the collected samples are representative directly affects the accuracy and precision of the test analysis, and is an important prerequisite for whether the measurement results can truly reflect the soil environment. Before soil sampling, the profile should be repaired and cleaned to remove the top layer of floating soil, and then samples should be taken from the typical central part layer by layer from bottom to top. [0003] According to soil science, soil topsoil generally refers to the 0-200mm thick soil layer in ...

AI Technical Summary

Problems solved by technology

Its disadvantages are: it is inconvenient to carry out horizontal sampling, the samples cannot be stratified accurately, and the profile characteristics of soil samples are difficult to distinguish; sampling is time-consuming and laborious, and the samples in the soil drill need to be manually collected after sampling; the amount of samples collected each time is small, and it is necessary to Continuous collection multiple times, low work efficiency, only suitable for the collection of a small number of samples; in addition, due to its relatively high degree of specialization, relatively complex structure, many parts and components, it is inconvenient to use and maintain

Its disadvantages are: the workload of sample collection is relatively large; it is inconvenient to carry out vertical sampling, and the soil layer structure of the facility soil and the root system of plants with close plant distances in the planting soil are greatly damaged by digging holes; at the same time, the sample Collection is often done manually

[0007] In addition, due to limitations in the use of existing soil samplers, soil collection is generally done through a variety of different soil samplers, which can easily cause large systematic errors between samples and affect the accuracy of test analysis.
