Description
Technical field
The utility model relates to experiment appliance technical field, more specifically, relates to a kind of separator improving soil animal escapement ratio and collection efficiency.
Background technology
Soil animal plays a part analyst and reducer in natural ecosystems, they can by Residue decay vegeto-animal in soil, thus to be beneficial to microorganism complicated organic substance decomposing be simple inorganic matter, and be discharged in environment and again utilize for plant, to Cycle of nutrients such as promotion carbon in soil, nitrogen, phosphorus, there is extremely important effect.Meanwhile, soil animal all plays very important effect to the formation of soil, growth, physicochemical structure and its aspect such as water binding capacity, heat insulating ability.Research confirms, the soil animals such as protozoa, nematode, mite class, springtail, maggot and Large Arthropods have participated in the initiating process of material recycle to a great extent directly, especially they are cooperated with edaphon, facilitate the transformation and cycling of the effective nutriment of plant.
Therefore, Soil Animals Community, as one of biological components indispensable in the ecosystem, is not only the important biomolecule index of soil fertility, and closely related with the biogeochemical cycle of the formation of soil, growth, succession and the ecosystem.In recent years about Land-Use, fertilizer application condition, vegetation pattern, nitrogen deposition, heavy metal pollution of soil, pesticide pollution, acid rain etc. on the impact of soil animal community structure and species diversity and Study on mechanism increasing, in these researchs, a most key technology is exactly be separated accurately and efficiently and collect soil animal.But, because soil animal build is often less, enormous amount, this makes to use at present the simple small-sized dry funnel method that wets often to occur that workload is huge when being separated and collect soil animal, and it is few to collect quantity, and collecting efficiency is low, even occur because escape route is few, soil animal has little time in a short time to escape out from soil because lasting light-illuminating temperature raises and is scalded dead phenomenon by scorching hot, therefore, have impact on the comprehensive and accuracy being separated soil animal and collecting.
Summary of the invention
Technical problem to be solved in the utility model is the above-mentioned defect overcoming prior art existence, provides a kind of separator improving soil animal escapement ratio and collection efficiency.
The purpose of this utility model is achieved by the following technical programs:
