Embodiment 1

[0041] like figure 1 As shown, it includes a culture device cover 1, a partition 2 that distinguishes the treated soil from the control soil, and a circular culture device 4 and a collection device 6 that are quickly connected by pin holes and locating pins.

[0042] Axisymmetric rail grooves 3 are respectively provided on the inner surfaces of the culture device 4 and the collection device 6, and the rail grooves 3 are 2 mm deep and 2 mm 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 culturing 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 culturing device 4 is located on the outside of the rail groove and is symmetrically provided with a pin hole A 7a and a pin hole B 7b, respectively. A 7a and pin hole B 7b are 2mm deep, 3mm wide and 1mm high.

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

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 soil animal avoidance test device and application, and in particular relates to a springtail avoidance test device and its application. Background technique [0002] With the deterioration of the global 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 assessment methods and technologies, the long-term research on soil quality assessment has focused on the detection of the concentration and chemical forms of pollutants in the soil, and little attention has been paid to the interaction between pollutants, soil and organisms. Considered because it is difficult to assess the biotoxic effects of pollutants on the soil environment. In the past 20 years, ecological risk assessment has gradually emerged. Based on ecol...
