Description

Device for assisting in pretreatment of volcanic lava wetland soil sample

Technical Field

The utility model belongs to the technical field of wetland investigation tools, and particularly relates to a device for assisting in pretreatment of a volcanic lava wetland soil sample.

Background

The Hainan island volcanic lava wetland is the only unique tropical volcanic lava wetland in China, is mainly distributed in the areas of seaports, clarity and the like in the North region, is especially most typical in the areas of seaports sheep mountain, is most widely distributed, and has a younger plant succession history different from the surrounding environment.

The influence of ecological environment fragmentation on plant diversity is one of the research hotspots in the field of ecology. Although there are some studies currently on the impact of habitat fragmentation on plant diversity, such as: the Aguilar et al (2019) study found that ecological environment fragmentation resulted in changes in the environment in which plants survived, thereby affecting plant propagation, plant offspring showed overall genetic erosion, plant germination, survival and reduced growth. Also researchers have explored the impact of habitat disruption on community species diversity, and found that disruption itself tends to increase species diversity when the total amount of habitat is large, but if the total amount of habitat is small, disruption itself reduces species diversity (Rybicki et al 2020). However, it is not clear whether the ecological environment fragmentation is a positive effect or a negative effect on plant diversity, mainly because the explanation of the mechanism of the influence of the ecological environment fragmentation on plant diversity lacks further research, especially for the Hainan island volcanic lava wetland, and the degree of ecological environment fragmentation of the Hainan island volcanic lava wetland is still further analyzed.

In the past, researches on the influence of ecological environment fragmentation on the diversity of wetland plants are mostly carried out from a single factor, so that the influence on the diversity of the plants is still unclear; the method does not relate the physical and chemical properties of plants and soil to soil microorganisms, analyzes the coupling relation among the plants and the soil microorganisms, and explores the regulation and control mechanism of the ecological environment crushing on the plant diversity of the wetland. It is therefore necessary to explore the impact of habitat disruption on plant diversity from a combination of soil and microbial factors. In the volcanic lava wetland soil field investigation process, a plurality of sampling points are used for collecting a large amount of soil sample water, and the soil sample needs to be subjected to drainage pretreatment on site, namely water in the soil sample naturally flows out, so that the situation that partial substances in the soil are taken out by water is reduced as much as possible. During specific operation, a worker needs to carry the sampling bag, seal the sampling bag after water samples flow out from the water outlet at the bottom of the sampling bag, and separately collect the discharged water. In the operation process, workers need to carry the sampling bag for a long time, the labor intensity of the work is high, and other works cannot be carried out in the process. It is necessary to develop a device for assisting in the pretreatment of the soil sample of the lava wetland that reduces the labor intensity.
