OUTDOOR SAMPLING LITTERCASE APPARATUS FOR CONTROLLING MIGRATIONS OF SOIL FAUNA

摘要

The present invention relates to a liter case device, and more particularly, a mesh network having various mesh sizes (lattice range: 10㎛ ~ 4mm) made of a polyester-based thin film material that is strong against corrosion according to the size of the soil animal population By attaching the cover to the upper and lower parts of the main body to physically restrict the movement and access of the soil fauna set as a specific target in the plant litter decomposition process, or to allow the selection, the carbon cycle and material circulation in the soil ecosystem are affected. It is possible to identify the contribution rate of various soil animals that affect the soil and the quantitative liter decomposition rate according to time series changes, and the height of the body can be freely adjusted so that it can be maintained the same as the natural soil ecosystem and environmental condition of the liter layer. It is possible to prevent in advance the state in which the liters (deciduous leaves) inside the body are artificially compressed with each other and become too wet, and the body is fixed with a fixing pin so that the liter decomposition rate measurement and sampling can be made continuously for a long time in the outdoor field. It relates to a liter case device for outdoor sampling that can control the movement of soil animals to withstand adverse weather conditions such as strong wind, heavy rain, and heavy snow.
