Description
Technical field
The utility model belongs to pathogenic soil thing separation technology field.More particularly, to a kind of novel standard soil line
Worm separator.
Background technology
Nemas is a class disease for many plants, and the direct harm of plant nematode is mainly harm plant
Bud, leaf, stem and root, make crop failure, cause huge economic losses.And the superficial cut that causes of nematode add fungi and
The chance of bacterium invaded plantses, transfer of the nematode between Different Crop also easily causes the propagation of virosis, therefore soil nematodes is
One of important indicator of soil health.Nematode is always one of emphasis monitoring object of inspection and quarantine work, because its build compared with
It is small, visually it is difficult to see, and be deposited in plant root, soil, fresh water, humans and animals, bring very big inconvenience to research.Cause
This, the separation of nematode is the first step of quarantine and research work.
At present, the conventional method of nematode separation includes modified Baermann funnel method, screening elutriation method, Centrifugal Flotation method and tray
Method separates nematode etc. from soil.Wherein, modified Baermann funnel method, because having the advantages that simple, cost is low, is the most frequently used one kind
Method, this method is the hydrotaxis and the weight of itself using nematode, and soil is departed from successively.
But modified Baermann funnel method also still suffers from problems, such as：1）When the matrix such as soil are more fine and smooth, mesh screen is easily blocked up
Plug；2）Mainly use paper handkerchief as separating layer in upper funnel, paper handkerchief immersion is fragile, and soil is easily caused in separation process with water
Stream flows into bottom, and soil and paper handkerchief are not easily taken out after the completion of separation；3）Isolated nematode has many death；4）One leakage
Bucket can only separate a sample, space-consuming, low separation efficiency；5）The easy aging of emulsion tube of its lower portion connection, Er Qieyong
When clip clamps emulsion tube, emulsion tube is easily sticked to together, so that being resulted in blockage when discharging water；6）Separator, especially
The sample pipe of nematode, does not seek unity of standard after separation, is brought inconvenience to substantial amounts of sample presentation sample work in quarantine.
