Embodiment 1

[0041] like figure 1 As shown, it includes a culture device cover 1, a partition 2 for distinguishing treatment soil and control soil, and a ring-shaped culture device 4 and a collection device 6 that are quickly connected through pin holes and positioning pins.

[0042] The inner surfaces of the cultivating device 4 and the collecting device 6 are respectively provided with axisymmetric rail grooves 3, the rail grooves 3 are 2mm deep and 2mm wide.

[0043] The culture device 4 includes a sieve plate 5a, a bottom plate 5b, and pin holes including a pin hole A7a and a pin hole B7b. The culture device 4 is a transparent hollow cylinder with an inner diameter of 55 mm, a thickness of 5 mm, and a height of 55 mm. The bottom of the culture device 4 is positioned at the outside of the track groove and is respectively symmetrically provided with pin holes A 7a and pin holes B 7b. A 7a and pin hole B 7b are 2mm deep, 3mm wide and 1mm high.

[0044] like Figure 5 As shown, the bott...

Abstract

The invention discloses a springtail avoidance test device and application thereof. The test device comprises a culture apparatus cover, a partition plate differentiating treated oil from control soil, a culture apparatus and a collection apparatus. The bottom of the culture apparatus is equipped with perforated sieve plate and a base plate without hole. The inner surfaces of the culture apparatus and the collection apparatus are respectively equipped with an axisymmetric rail groove, and the partition plate is in inserted connection with the culture apparatus and the collection apparatus through the rail groove. The test device provided by the invention solves the problems of complicated operation of water floating method, error caused by position uncertainty of re-inserted partition plate, data invalidation due to easy loss of springtails, and errors caused by movement of springtails from one partition plate side to the other side along with a gap, and the like in existing springtail avoidance test.

Description

technical field [0001] The invention belongs to the technical field of a soil animal avoidance test device and its application, and in particular relates to a collembola avoidance test device and its application. Background technique [0002] With the deterioration of the earth's environment, people pay more and more attention to environmental issues, and the accumulation of toxic and harmful substances in the soil will affect the stability and sustainability of the soil ecosystem. Due to the limitations of soil pollution evaluation methods and technologies, the long-term research on soil quality evaluation has focused on the detection of the concentration and chemical form of pollutants in the soil, and little attention has been paid to the interaction between pollutants, soil and organisms. Considered, due to the difficulty in assessing the biotoxic effects of pollutants on the soil environment. In the past 20 years, ecological risk assessment has gradually emerged. Based...
