Abstract
The utility model relates to a small-and-medium-sized soil animal separator based on farmland landscape and ecological function studies. The small-and-medium-sized soil animal separator based on farmland landscape and ecological function study comprises an inner funnel, an outer funnel, a bulb, an objective table and an animal container. The inner funnel and the outer funnel are vertically arranged in a nested mode. The diameter of an upper opening of the inner funnel and the height of the inner funnel are both smaller than the diameter of an upper opening of the outer funnel and the height of the outer funnel. Fixed strips are arranged between the inner funnel and the outer funnel so as to ensure that a gap is reserved between the inner funnel and the outer funnel and the relative positions of the inner funnel and the outer funnel keep unchanged. The bulb is located at the bottom of the inner funnel. The objective table is placed on the top of the inner funnel. The animal container is located below an outlet in the bottom of the outer funnel and contains ethyl alcohol with the mass concentration of 75%. Compared with a traditional device, the small-and-medium-sized soil animal separator has the advantages that the stability is good; since a gauze element is not needed for separation, the problem that soil can fall into the animal container for receiving insects when soil particles are too small is avoided; when the soil water content is high, water can not flow into the animal container below the outlet of the outer funnel.
