Abstract
The utility model relates to a device for determining substance for attracting nematodes, which belongs to the technical field of plant nematode prevention and cure research instruments. The device comprises a device (1) marked with a scale ring on the back side; a plurality of spotting grooves (2) are formed at the outer edge part of the frontal surface of the device (1), a groove (3) is formed in the center of the device (1), a channel (4) is formed between the spotting grooves (2) and the groove (3), the bottom of the channel is ensured smooth, and the number of the spotting grooves (2) isdetermined as required; and the device (1) is made of transparent material. Compared with the prior art, the utility model has the advantages of simple structure, convenient operation, intuitive result and easy comparison; and the utility model can be widely used for determining the attraction of the substance to the nematodes.
Description
Technical field:
The utility model relates to the device that a kind of mensuration is lured the nematode material, platymiscium control of nematode research Instrument technology field.
Background technology:
Plant nematode is the important phytopathy original of a class, at present mainly by using chemical pesticide to prevent and treat.But the drawback of chemical pesticide more and more causes people's attention, as environmental pollution, and to killing and wounding of non-target organism, the polypide resistance to the action of a drug, residues of pesticides or the like.Because novel pesticide development difficulty and cost constantly rise, and national governments emphasize environmental protection more, pay attention to the sustainable development of agricultural simultaneously, make the development of Plant nematode biological control that new opportunity arranged.
The biological control of Plant nematode mainly contains: throw in parasitic microbe and catch and kill with luring.Wherein lure and catch and kill in the process of control, mainly have stronger epigamic material to lure to Plant nematode to kill nematode then by filtering out certain in research.Scholar's testing program of being engaged in correlative study has nothing in common with each other, but mostly can not be rapid, demonstrates intuitively at the same terms, and two or more measured matters are to the power of nematode attracting ability under the identical time.Therefore, material is measured in research becomes important problem in the research trapping biocontrol of nematodes to the epigamic test apparatus of nematode.
By literature search, do not see the open report identical with the present invention.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency of prior art, and provides a kind of simple in structure, and easy to operate mensuration is lured the device of nematode material.
The utility model is made of the device (1) that reverse side is carved with the scale circle, wherein: the positive outer rim position of device (1) has several point sample grooves (2), there is a groove (3) in device (1) central authorities, have passage (4) between point sample groove (2) and the groove (3), channel bottom will guarantee that smoothly the quantity of point sample groove (2) is determined on demand; Device (1) selects for use transparent material to make.
The utility model compared with prior art has simple in structure, and is easy to operate, and visual result is easy to relatively wait advantage.Can be widely used in and measure the epigamic of material nematode.
Description of drawings:
Accompanying drawing is the structural representation of the utility model embodiment.
Embodiment:
The utility model is made of the device 1 that reverse side is carved with the scale circle, wherein: the positive outer rim position of device 1 has 3 point sample grooves 2, and installing 1 central authorities has a groove 3, has passage 4 between point sample groove 2 and the groove 3, channel bottom is level and smooth, and the quantity of point sample groove 2 is determined on demand; Device 1 selects for use transparent material to make.
Measuring two kinds of materials to root-knot nematode second instar larvae epigamic step is:
1, will install 1 is placed on the objective table of stereoscope;
2, respectively test substance is put into device (1) two point sample grooves 2 on every side;
3, in a point sample groove 2, splash into clear water in contrast;
4, in the groove 3 of central authorities, splash into the distilled water that contains the root-knot nematode second instar larvae;
5, distilled water is dropwise splashed in the passage 4, make its connection;
6, leave standstill 10～15 minutes;
7, open stereoscope, adjust focal length, observe the quantity of nematode in each passage 4 and the distance of motion, data are done contrast and are calculated conclusion in the utilization clear water.
Claims (1)
1, a kind of mensuration is lured the device of nematode material, it is characterized in that this device is made of the device (1) that reverse side is carved with the scale circle, wherein: the positive outer rim position of device (1) has several point sample grooves (2), device (1) central authorities have a groove (3), have passage (4) between point sample groove (2) and the groove (3).
