Meadow vegetation root sampling and surface soil stripping device

Abstract

The meadow vegetation root system sampling and surface soil stripping device comprises an outer barrel with the bottom being open and a sampling barrel arranged in the outer barrel, a vertically-downward positioning column and a protective edge extending outwards are installed at the bottom of the outer barrel, a telescopic frame is arranged on the outer wall of the outer barrel, universal wheels are installed on the telescopic frame, and the universal wheels are arranged on the outer wall of the outer barrel. The top of the sampling barrel is coupled with a longitudinally arranged sampling motor, the outer wall of the sampling motor is fixedly connected with a sliding lifting cylinder, and the sliding lifting cylinder penetrates out of the top of the outer barrel and is connected with a console at the top end; the sampling barrel comprises an upper drying and separating area and a lower sampling area. The device is used for pasturing area grassland vegetation root system research work, sample plot plant root systems can be completely obtained, root system surface soil can be rapidly dried and separated according to test requirements, convenience is provided for pasturing area grassland vegetation ecology and ecological restoration plant breeding research, and the device is high in practicability. Important research data are provided for drought resistance and disaster reduction in pasturing areas and sustainable development of agriculture and animal husbandry, the automation degree is high, and the acquisition speed is high.

Description

technical field [0001] The invention relates to a meadow vegetation root system sampling and surface soil stripping device. Background technique [0002] As an important link in the material cycle process of the atmosphere, soil, and plants, the root system has important functions such as absorbing soil moisture and fertilizers, and resisting natural disasters. It is also an important part of the structure and function of the ecosystem. Parameters such as the depth, shape, and biomass of vegetation roots are affected by many aspects such as species type and hydroclimatic conditions, especially closely related to soil moisture content, which is an important indicator of drought in agriculture and animal husbandry. In the context of frequent disasters, it is of great significance to explore the vegetation root ecology and its relationship with drought and carbon cycle. However, because the root system grows underground and the root system branches are complex, it has always b...

Problems solved by technology

However, because the root system grows underground and the root system branches are complex, it has always been difficult to conduct in-situ complete sampling research methods, which makes the research results deviate from the actual situation.
