Temperature-adjustable small and medium-sized soil animal separator researched based on landscape architectures and ecological functions

Abstract

The invention relates to a temperature-adjustable small and medium-sized soil animal separator researched based on landscape architectures and ecological functions. The soil animal separator comprises the following components: a funnel, a heating table, an object table and an animal container, wherein the funnel is vertically placed and is internally provided with bearing strips, the heating table is placed on the bearing strips, and a gap is formed between the heating table and the wall of the funnel; the object table is placed on the heating table, and a gap is formed between the object table and the wall of the funnel; the upper edge of the object table is lower than the upper edge of the funnel; the animal container is positioned below the bottom outlet of the funnel. The small and medium-sized soil animal separator has the advantages that the stability is excellent; because the soil animal separator does not use a screen for separating, the problem that soil falls into the animal container which is below the soil and is used for receiving worms when soil particles are small can be avoided; when the soil has high water content, water does not flow into the animal container below; and when the environment temperature change is large, the temperature of the heating table can be adjusted by a temperature controller, the separation efficiency of soil animal can be conveniently improved.

Description

technical field [0001] The invention relates to the field of soil animal research, in particular to a temperature-adjustable small and medium-sized soil animal separator based on garden landscape and ecological function research. Background technique [0002] Tens of thousands of soil organisms live in the soil. They are an important part of the soil ecosystem. They participate in the decomposition of biological residues, change the soil properties, and affect the formation and development of soil and the material cycle and energy flow of the ecosystem. are all significant. Soil animals are an important group in the composition of soil organisms. It generally refers to animals that spend their whole life or a certain developmental stage in the soil and have a certain impact on the soil. There are many types of soil animals. Except for typical marine animals, most animal phyla are represented in soil, mainly involving protozoa, flatworms, rotifers, linear animals, annelids,...

AI Technical Summary

Problems solved by technology

But the inventor found some problems in actual use: First, the stability of the device is relatively poor. Since the whole device is divided into upper and lower parts, and the instrument itself has a certain height, in order to prevent the instrument from falling sideways, the stability of the device is greatly affected. The requirements are relatively high; secondly, when separating some soil samples with particularly small soil particles, the soil will also fall into the plate below through the gauze, which is helpful for selecting small soil animals (especially mites and collembola, etc.) from the plate in the later stage. Small soil animals that need to be sorted under a microscope) cause great difficulties; again, when some soils with high water content are separated, water will flow into the plate below, causing too much water in the plate, diluting the concentration of the alcohol solution, Sometimes it will cause the alcohol solution to overflow; finally, when the ambient temperature changes greatly, it is necessary to replace the bulb with a more suitable wattage in time to improve the separation efficiency
