In situ heating drive away specimen collection device for soil fauna

Abstract

A soil animal community in-situ heating and driving away specimen collection device belongs to the technical field of soil zoology, and is composed of: the sampler (1) is a structure for collecting soil samples, and the lower end of the sampler (1) is a drill bit ( 3) The middle is the drill pipe (17), the upper end is the force wheel (28), the force wheel (28) is connected with the unearthed pipe (7) through the anti-track bearing (29) and the anti-track pipe (30) . The upper end of the anti-following pipe (30) is connected with the unearthed pipe (7), and the lower end is free. An anti-following bearing (29) is arranged in the middle of the inner surface of the anti-following pipe (30). The anti-following pipe (30) passes through the anti-following bearing (30). 29) is connected with the upper end of the drill pipe (17). The invention is simple to manufacture, heats the soil in situ, drives the soil animals out of the specific specimen bottle, so that the result is very accurate, and because the carrying and setting of the soil sample is reduced, the use is also very convenient.

Description

technical field [0001] The invention relates to a sample collection device for in-situ heating and driving away from soil animal communities, and belongs to the technical field of soil zoology. Background technique [0002] Soil fauna is a general term for various animals that live in soil and under fallen leaves. As important consumers in the material cycle of the ecosystem, soil animals play an important role in the ecosystem. On the one hand, they actively assimilate various useful substances to build themselves, and on the other hand, they return the excrement products to the environment to continuously transform the environment . Currently, the researchers' tool for collecting soil animals is the Tullgren dry funnel, which uses light and heat from lights to drive soil animals away. However, the collection of soil and the expulsion of soil animals are relatively cumbersome. It is necessary to collect soil samples of a fixed size, and the soil samples need to be carried...

AI Technical Summary

Problems solved by technology

However, the collection of soil and the repelling of soil animals are relatively cumbersome, and soil samples need to be collected one by one with a fixed size, and the soil samples need to be carried to the laboratory for at least 24 hours of light repelling

The variety of tools used and the long drive-off time make the collection of soil animal specimens extremely complicated, time-consuming, labor-intensive and expensive. After one experiment, multiple operators are often exhausted.
