Abstract
The utility model is a nematode filter cloth, and characterized in that: the nematode filter cloth is pressing molding by nonwoven technology of 2-5 layers chemical filament and the thickness is 0.2-0.6mm, and the irregular spacing of 0.05-0.3mm is formed between the surface fibers. The utility model is strong in performance of water and air permeability and the air bubble layer is difficult to form between the sample and water layer when using, which is beneficial for the nematodes to escape and more beneficial for the discharging of the air bubble when placed in water. The utility model has remarkable effects of improving the separation efficiency of the nematodes and reducing the impurities of the nematodes separation liquid.
Description
Technical field
The utility model relates to a kind of plant quarantine and separates articles for use, particularly a kind of nematode filter cloth with the activity plant nematode.
Background technology
The nematode filter cloth uses in the lump with " modified nematode separator " or " tray nematode separator ", when sample material being carried out the nematode separation, need on the tray of " modified nematode separator " or " tray nematode separator ", place mat one bracing cable worm filter cloth, put into the sample material of nematode to be separated then: the soil sample 100-200g that contains nematode, or the vegetable material (as root system and stem) that contains nematode to be cut into the segment of 0.5-1.0cm an amount of, make water enter from the separator edge, cover and soak into, through 10-24 hour, be connected under the sebific duct of separator with empty beaker or recessed ware, unclamp tongs gently, contain the nematode of separating in a large number in the water that flows out, close tongs, and in separator, replenish clear water gently, can collect nematode once more.
Because the nematode isolation technics need be filtered the material of nematode, there is not fixing filtering material at home, often use the multilayer gauze, double-deck sanitary tissue, blotting paper in addition when nematode separates without filtering material, in the nematode parting liquid, contain a large amount of impurity, directly influence the correct judgement that nematode separates.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, and the nematode filter cloth that a kind of water-permeable and air permeable performance is strong, help the effusion of nematode is provided.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of nematode filter cloth, is characterized in, it adopts non-woven technology compression moulding by the fine long filament of 2-5 stratification, and its thickness is the 0.2-0.6 millimeter, and forms the irregular spacing of 0.05-0.3 millimeter between the surface fiber silk.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of nematode filter cloth is characterized in, filter cloth be shaped as circle, its diameter is the 160-200 millimeter.This is a best-of-breed technology scheme of the present utility model.
The utility model water-permeable and air permeable performance is stronger, be difficult in use between sample and water layer, forming bubble layer, help the effusion of nematode, when placing water, be more conducive to the discharge of bubble, to separative efficiency that improves nematode and the impurity that reduces in the nematode parting liquid, effect is obvious.The utility model adopts non-woven technology, and production prices are cheap; Cost only is 1/5th of an external like product, and performance is more superior.The utility model design service life also can repeatedly use through high temperature treatment for once.The utility model nematode filter cloth only needs it to be seated on " modified nematode separator " or " tray nematode separator " in use, can carry out the routine operation that nematode separates.
