Description
Technical field
The invention belongs to water body detection field, and in particular to a kind of cultivation water nitrite is quick
Detection kit.
Background technology
In intensive culture water body, aquatic livestock breeding density is high, feeds the abundance of food greatly,
Substantial amounts of residual bait, animals and plants excreta, dead residuum etc. are easily accumulated in breeding water body nitrogenous
Organic matter, in addition, undressed breeding wastewater and industry, sanitary sewage be discharged or by
Rain drop erosion enters breeding water body, causes breeding water body nitrite severe overweight.
Nitrite is exceeded to be easily caused harmful bacteria and conditioned pathogen largely grows, fish, shrimp
Constitution Deng cultivated animals declines, and anti-stress ability is poor, is easily attacked, caused by pathogen
The large area outburst of aquatic animal disease, huge economic loss is caused to raiser.
Common water quality detecting kit of nitrites is although easy to operate in the market, take
Band is convenient, but poor anti jamming capability, false positive, false negative result, sensitivity easily occurs
It is relatively low.And mostly pulvis or plurality of reagents be applied in combination, raiser in detection process often
The problems such as usage amount that can often run into pulvis is uncontrollable, reagent quality is rotten, ties detection
It is really inaccurate;Sometimes the detection reagent used is more, cumbersome, does not note detection knot slightly
Easily there is larger error in fruit.Chinese patent CN 102507553A, CN
103743727A, CN 104407097 is the examination for detecting breeding water body nitrite
Agent box, they are that common chemical indicator is mixed, and the former reagent operation step is numerous
Trivial, reagent stability is poor, and the developing time of both rear reagents is a little long.
With the fast development of culture fishery, the cultivation risk of raiser is reduced, is badly in need of having
A kind of new detection is rapid, sensitivity is high, the content of nitrite detection reagent of steady quality
Box.
The content of the invention
In order to solve the above problems, the present invention provides a kind of cultivation water nitrite quick detection
Kit.
The cultivation water nitrite quick detection kit that the present invention is provided, it contains test
