Embodiment 1
[0028] Prepare the medium and small-sized soil animal separation equipment based on farmland landscape and ecological function research of the present invention according to the following steps (see figure 1 ).
[0029] Take a funnel with a height of 260mm and an upper diameter of 193mm as the inner funnel 1; take a funnel with a height of 350mm and an upper diameter of 260mm as the outer funnel 2; the inner funnel 1 and the outer funnel 2 are nested vertically, and the inner funnel 1 Three small pieces of wood with a thickness of 10mm are placed between the outer funnel 2 as a fixing bar 8; the lower part of the inner funnel 1 is placed with a light bulb 3 (30w incandescent lamp), which is connected to the power supply through the gap between the inner funnel 1 and the outer funnel 2.
[0030] A petri dish with a diameter of 200mm (used as the stage 4) is placed on the inner funnel 1 for placing soil samples. The height of the edge of the soil sample is required to be slightl...
