In a preferred embodiment of the present invention, the floating cover of the shading is strutted by skeleton.
In a preferred embodiment of the present invention, Daphnia magna can not pass through the mesh of the string bag.
The present invention solves defect present in background technology, and the present invention possesses following beneficial effect：
（1）By setting the floating cover of the shading that swims on the water surface, due to the floating lighttight characteristic of cover of shading, by above the water surface from
Right light provides a dark light and thinks environment to being covered and will not be irradiated in water for the waters of the floating cover bottom of shading, then this
When enrichment rod in blue light could be as small disturbed as possible, play the effect that its light attracts Daphnia magna.
（2）Because fibrous layer has been wrapped up in lamp chamber periphery, it can block blue light to a certain extent, therefore shading is floated cover and can arranged
Except available light as much as possible interference, blue light light in lamp chamber is strengthened in contrast, and lifting blue light attracts the ability of Daphnia magna.
（3）By the pendency of messenger wire, enrichment rod can be suspended on depth predetermined below the water surface, be seen during suspention without personnel
Pipe, also removes the situation that personnel's interference enrichment rod attracts Daphnia magna from.
（4）Animal manure is just the conventional foodstuff of Daphnia magna with algae slurry, is also lured while being attracted using blue light using food,
After being attracted to Daphnia magna on enrichment rod, Daphnia magna just will not leave enrichment rod easily.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples；
Fig. 1 is the structural representation of the first preferred embodiment of the present invention；
Fig. 2 is the structural representation of second of preferred embodiment of the present invention；
In figure：1st, the floating cover of shading；2nd, messenger wire；3rd, it is enriched with rod；4th, lamp chamber；5th, fibrous layer；6th, skeleton.
Embodiment
Presently in connection with drawings and examples, the present invention is further detailed explanation, and these accompanying drawings are simplified signal
Figure, only illustrates the basic structure of the present invention in a schematic way, therefore it only shows the composition relevant with the present invention.
A kind of primary Daphnia magna enriching apparatus in field, including：The floating cover of shading, and it is arranged on some of the floating cover bottom of shading
Individual enrichment rod, enrichment rod includes the lamp chamber at mandrel and is wrapped in the fibrous layer on lamp chamber surface, and the floating cover of shading is by lighttight
Fabric is made, fabric bottom surface uniformly to be provided with several cursory.
By setting the floating cover of the shading swum on the water surface, due to the floating lighttight characteristic of cover of shading, above the water surface
Available light provides a dark light to covering and will not be irradiated in water, for the floating waters for covering bottom of shading and thinks environment, then
Now the blue light in enrichment rod could be as small disturbed as possible, plays the effect that its light attracts Daphnia magna.
Wherein as shown in figure 1, the floating cover of shading in the first preferred embodiment of the present invention is the circular configuration of umbrella, this
The floating cover of shading for planting structure is adapted to the primary Daphnia magna in collection field of small range fixed point.
Wherein as shown in Fig. 2 the floating cover of shading in second of preferred embodiment of the present invention is extend along bank and tool
There is the strip structure of breadth, the floating cover of shading of such a structure is adapted to the primary Daphnia magna in collection field pinpointed on a large scale, Daphnia magna
The shallow water areas for being gathered in waterfront edge, along the floating cover of riverbank arrangement shading, can targetedly gather Daphnia magna more.
Lamp chamber is the blue-ray light that connection battery is provided with sealing structure, lamp chamber.Because fibrous layer has been wrapped up in lamp chamber periphery,
It can block blue light to a certain extent, therefore the floating cover of shading can exclude available light interference as much as possible, contrast reinforcing lamp
Blue light light in chamber, lifting blue light attracts the ability of Daphnia magna.
Enrichment rod is connected to the floating cover bottom surface of shading by messenger wire suspension.By the pendency of messenger wire, enrichment rod can be suspended on
Predetermined depth, keeps an eye on during suspention without personnel below the water surface, also removes the situation that personnel's interference enrichment rod attracts Daphnia magna from.
Fibrous layer on enrichment rod is stained with fowl and animal excrement and algae pulp mixture.Animal manure is just the tradition of Daphnia magna with algae slurry
Food materials, are also lured while being attracted using blue light using food, and after being attracted to Daphnia magna on enrichment rod, Daphnia magna is just not
Enrichment rod can be left easily.
Balancing weight is additionally provided with enrichment rod, balancing weight can offset the buoyancy of lamp chamber, make the entirety of enrichment rod close
Density of the degree more than or equal to water.
The acquisition method that a kind of primary Daphnia magna enriching apparatus in use field is carried out, comprises the following steps：
S1 deploys the floating water surface that covers on of shading, enrichment rod is suspended in the following water of the floating cover of shading, while opening in lamp chamber
Lamp, makes light pass through the gap of fibrous layer；
S2 will be enriched with rod after enrichment rod has attracted a certain amount of Daphnia magna, using the string bag with the body of rod and be dragged for from the floating cover bottom of shading
Rise and enrichment rod is rinsed in collecting pit；
S3 separates and collects the Daphnia magna in pond after the fowl and animal excrement in collecting pit and algae pulp mixture are precipitated.
The floating cover of shading is strutted by skeleton, can so avoid wind, wave etc. from disturbing, and skeleton can ensure that the floating cover of shading is thorough
Deploy at bottom.
Daphnia magna can not pass through the mesh of the string bag, so can in order to as far as possible from water take out enrichment rod when not
Daphnia magna can be allowed to be lost in.
The desirable embodiment according to the present invention is enlightenment above, by above-mentioned description, and related personnel completely can be with
Without departing from the scope of the technological thought of the present invention', various changes and amendments are carried out.The technical scope of this invention
It is not limited to the content on specification, it is necessary to determine the technical scope according to the scope of the claims.
