Abstract

The invention provides a quantitative collection box of little arthropod soil animals. The quantitative collection box comprises a box body and a separation and collection device, wherein the separation and collection device is arranged in the box body; a heating device is arranged on a top cover of the box body; a refrigerating device is arranged at the bottom of the box body; the separation and collection device comprises a sample holder, a bearing plate and one or more separator-collectors; the bearing plate is arranged on the sample holder and is provided with bearing holes; each separator-collector is arranged in the corresponding bearing hole and comprises a sample cup, a sieving net, a net hoop and a collection vessel; and each sieving net is arranged at the lower end of the corresponding sample cup and then is connected with the corresponding collection vessel after being fixed by the corresponding net hoop. The quantitative collection box disclosed by the invention can be applied to separation of the little arthropod soil animals and can accurately quantify the little arthropod soil animals in a soil sample. Moreover, the quantitative collection box provides a lucifugal environment so as to prevent easily-photolyzed substances in soil from being decomposed, and thus the actual condition of the soil can be really reflected.

Description

[0001] technical field [0002] The invention relates to the technical field of ecological environment, in particular to a quantitative collection box for small arthropod soil animals, which can effectively separate small arthropod soil animals. [0003] Background technique [0004] Risk assessment of contaminated soil is a key link in risk management and restoration of contaminated soil. Soil animals are the ecological receptors that need to be considered in the ecological risk assessment of soil pollution. Among them, small arthropod soil animals such as collembola and mites are commonly used ecological receptors in soil ecological risk assessment and soil ecological benchmark formulation. [0005] In order to separate small arthropod soil animals from the soil, the Italian scholar Berlesc invented the insect drying funnel at the beginning of the 20th century, which was improved by Tullgren and widely used. It is called the Tullgren method or the dry funnel method. Its ...
