Capture separation method for soil animal

Abstract

Disclosed is a capture separation method for a soil animal. The capture separation method for the soil animal comprises the steps that firstly, the surface soil animal is captured; secondly, a container is prepared, and clean water is placed into the container; thirdly, a mixed solution with the animal is poured on to gauze or a screen net above the container, and water or the solution in the mixed solution is filtered away; fourthly, a sample containing the gauze or the screen net is repeatedly washed and filtered in the clean water, and soil particles and impurities are filtered away; fifthly, tweezers are used for picking out leaves and large impurities inside the sample on the gauze; sixthly, the sample inside the gauze is guided into the specimen container; seventhly, the gauze is used for blocking a bottle opening of the specimen container, the bottle opening is slightly inclined, and clean water inside the container is filtered out; eighthly, alcohol or preservation liquid is guided into the specimen container. The capture separation method is used for capturing and separating the soil animal.

Description

technical field [0001] The invention relates to a method for capturing and separating soil animals. Background technique [0002] Soil animals move at different levels in the underground ecosystem, from the surface to the underground. According to their different living habits, the capture and separation methods adopted are also different. [0003] The trap method is mainly used to capture large soil animals that are active on the surface. During the actual capture process, affected by wind, precipitation, etc., some impurities are usually mixed into the plastic cup. These leaves, branches, soil particles and other impurities are mixed with large soil animals on the surface. Sorting methods that have been used include hand picking, using tweezers, etc. to directly pick large soil fauna specimens out of plastic cups. However, this will bring the following problems: 1) The speed is slow and the work efficiency is low; 2) When the specimen is clamped with tweezers and other t...

Problems solved by technology

However, this will bring the following problems: 1) The speed is slow and the work efficiency is low; 2) When the specimen is clamped with tweezers and other tools, it will cause damage to the specimen, such as pinching off the wings and antennae of the specimen, some animals such as millipedes, There are many body segments, if you use tweezers, it will be broken into many segments, and the degree of damage will be great, which will increase the difficulty of later specimen identification and parameter acquisition; 3) There is a risk of missing specimens, insects mixed in leaves and soil particles Inside, some animals with darker colors and relatively smaller bodies are often difficult to distinguish with the naked eye, and it is not easy to pick them out in the wild, which reduces the accuracy of sample investigations
