Technical field

The invention relates to the technical field of sampling and preparing samples for testing, specifically a soil moisture detection device for forest land survey.

Background technique

In recent years, research on water conservation and soil and water conservation forest construction technologies has already begun. The Taihang Mountain Ecological Forestry Project has built multiple experimental demonstration bases and created tens of thousands of acres of demonstration test forests. At the same time, more scientific research has been conducted on the construction of water source conservation forests, mountain forest restoration, and vegetation and hydrological cycles. The ecological environment around the water sources and catchment areas around the forest land has deteriorated, and water and soil erosion has continued to intensify. Then the forest land has a negative impact on water and soil. The impact of loss has always been based on water conditions and the conditions between forest vegetation and local water conditions and water resources. The relationship between forest and water is an important issue in forestry production activities and improving the ecological environment. The interaction between forest vegetation and water , therefore, the simulation and evaluation of hydrological and ecological benefits such as forest vegetation intercepting precipitation, reducing the kinetic energy of raindrops, increasing soil infiltration, etc. to conserve water sources, improve water quality, improve soil, and conserve soil and water are the key to forest hydrology research.

Soil moisture refers to soil moisture content, which is an important physical parameter of soil. Soil water is the link between surface water and groundwater, and plays an important role in the formation, transformation and consumption of water resources. Soil moisture status plays an important role in rainfall runoff and evapotranspiration. development and ecosystem changes are of great significance.

Therefore, humidity is one of the important data for forest land survey, and forest soil moisture detection requires soil that is deeper than the ground as a sample, which can generally reach one or two meters. It is very laborious to dig the depth of one or two meters manually. Generally, a drill is used to drill the ground. It is difficult to drill holes, but it is also troublesome to obtain the soil one or two meters deep into the ground after drilling. Therefore, it requires more manpower and is slower to adopt, which in turn affects the efficiency of forest soil moisture detection.
