Description

A peat soil sampling device

technical field

The utility model relates to the technical field of soil sampling tools, in particular to a peat soil sampling device.

Background technique

With the rapid development of China's economy and the acceleration of urbanization, the accompanying environmental problems have become increasingly prominent. Due to improper operation or management in the production process, more and more soils have been seriously polluted, and the pollution enters the plants through the root system. The growth of plants is inhibited, and heavy metal pollution has begun to reveal its impact on industrial and agricultural production and human health. On April 17, 2014, the Ministry of Environmental Protection and the Ministry of Land and Resources jointly issued the "National Soil Pollution Survey Bulletin". The survey results show: The total point exceeding the standard rate of the national soil is 16.1%, of which the slightly, lightly, heavily and heavily polluted points are 11.2%, 2.3%, 1.5% and 1.1%, respectively, so the treatment of polluted soil is imminent. In soil measurement and research, it is necessary to excavate and sample the soil. For deep soil sampling research, deep excavation is often used to sample. There are many types of soil sampling tools, such as shovels, hoes, drills, etc. , It takes a lot of manpower to reach the corresponding soil depth, which is time-consuming and labor-intensive, and it is easy to cause damage to surface vegetation. The soil sampling tools currently used have the defects of complex structure and inconvenient sampling. The functional modules of these soil sampling tools are relatively single, and they cannot perform deep sampling and multi-parameter measurement of soil.
