Accompanying drawing explanation
With detailed description of the invention this utility model done below in conjunction with the accompanying drawings and further illustrate, of the present utility model
Above-mentioned or otherwise advantage will become apparent.
Fig. 1 is the structural representation of embodiment 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is elaborated.
Embodiment 1:
Such as Fig. 1, this utility model includes fixing iron ring 1, cultivation fishing cage 2, buoyancy member 3, opening 4, fixed mount 5
With tying 7, wherein cultivation fishing cage 2 sidewall is provided with the fixing iron ring 1 of a more than circle, is provided with floating in described cultivation fishing cage 2
Power parts 3, described cultivation fishing cage 2 is arranged over fixed mount 5, and cultivation fishing cage 2 top is tying 7, logical at tying 7
Cross and be fixed on fixed mount 5 after cotton rope is tightened.
Fixing iron ring 1 struts cultivation fishing cage 2, forms the basic configuration of breeding cage, is unlikely to distort, and is conducive to
Water keeps certain shape.Generally cylindrical structural.
A circle buoyancy member 3 is contained in the upper end of cultivation fishing cage 2, and buoyancy member can select buoyant foam ball, buoyant foam
The quantity of ball can be allocated, by buoyancy member 3 make whole breeding cage the upper end moment some be positioned at above the water surface,
No matter the rising of water level or decline, all keep certain distance emerged so that the biology of cultivation can be at the water surface
Breathe, also can observe aquatic biological activity and counting at any time.
Opening 4 can be positioned at above buoyant device as dog-house and observation port, generally 20cm, by a slide fastener system
Become, when raising biology and feeding intake or observe aquatic biological activity situation, slide fastener can be opened and feed intake or observe.
The aperture of cultivation fishing cage 2 can determine different pore sizes according to the type of aquaculture organism, and the aperture of fish shrimp crab is each not
Identical.
When the experiment of pesticide water ecological risk assessment starts, place aquatile cultivation apparatus, according to kind difference by aquatic
Biological raising is in device.When reaching pesticide application condition, dispenser dosage and insecticide-applying way according to pesticide start dispenser,
Now pesticide starts to adsorb on rice leaf and fall into the water, and the pesticide fallen into the water starts to dissolve and adsorb to exist in water
Rice soil surface.Start in certain time to discharge water after dispenser terminates, rice field water in field is put into the aquatile experiment pool.With
Water in field and enter the pesticide on the aquatile experiment pool, partial action is in aquatile, and produces corresponding toxic action, separately
Outer portion starts hydrolysis or sedimentation absorption on bed mud.Final according to hydrobiological mortality rate, toxic effect, obtain
The value-at-risk of this kind of pesticide.Finally determine this kind of pesticide to different hydrobiological harm, for the Environmental risk management of pesticide
Offer data are supported.
1, experimental technique
By normal planting patterns rice cultivation in rice field, and normal management.9 observed samples points are set in testing front fish pond,
Cultivate with biological culturing device various for examination aquatile in each point respectively, treat the aquatile in biological culturing device
After growth is normal, spraying certain pesticide August when paddy growth contains the phase in rice field, formulation rate is 30g (effective ingredient)
/ mu, during spray medicine, the deep about 5cm of water in field, all enters fish pond, drainage procedure the most about 12h by water in field after 24h.From dispenser
Rear sampling determination paddy soil and certain pesticide and the residue dynamics of metabolite thereof in water in field；Certain is measured from paddy field drainage
Pesticide and metabolite residue dynamics in fishpond water and bed mud thereof.Observe aquatile in biological culturing device simultaneously
Impact.
2, test pesticide
30% certain pesticide wettable；Consumption 30g ai/ mu
3, result and discussion
1. the harm impact of prawn
Test processes ibid, from table 1: in the comparison pool, also begin to occur the phenomena of mortality, 14d mortality rate after 10d
Reach 8.9%.And shrimp starts death occur after locating Litang draining 1d, mortality rate is 2.2%；Draining 6d mortality rate reaches
After 15.5%, 14d, mortality rate reaches 20.0%.Showing under this experimental condition, certain pesticide rice field uses prawn d's
Harm risk is less.
The harm of certain pesticide prawn of table 1 affects result of the test (mortality rate, %)
2. the harm on Eriocheir sinensis affects
Test processes ibid, and from table 2, the Eriocheir sinensis in the comparison pool starts death occur, reaches after 14d after 3 days
5.0%.And after locating Litang draining 2d, death occurs in Eriocheir sinensis, after draining 3d, mortality rate is 13.3%.Show certain pesticide
When pesticide rice field uses, the hazardness to Eriocheir sinensis is little.
Certain pesticide of table 2 affects result of the test (%) to the harm of Eriocheir sinensis
4, conclusion
After dispenser 24h, water in field entering fish pond, in the comparison pool, also begins to occur the phenomena of mortality after 10d, 14d is dead
Rate reaches 8.9%.And shrimp starts death occur after locating Litang draining 1d, mortality rate is 2.2%；Draining 6d mortality rate reaches
To 15.5%, after 14d, mortality rate reaches 20.0%.Showing under this experimental condition, certain pesticide rice field uses Japan
Macrobrachium does not has big harm risk；Eriocheir sinensis in the comparison pool starts death occur after 3 days, reach 5.0% after 14d,
And after locating Litang draining 2d, death occurs in Eriocheir sinensis, after draining 3d, mortality rate is 13.3% hereafter to keep constant.Show
When certain pesticide rice field uses, the hazardness to Eriocheir sinensis is less.
This utility model provides a kind of biological culturing device being applied to the experiment of pesticide water ecological risk assessment, implements
The method of this technical scheme and approach are a lot, and the above is only preferred implementation of the present utility model, it is noted that
For those skilled in the art, on the premise of without departing from this utility model principle, it is also possible to make
