Description
Technical field
The utility model relates to a kind of incubator, particularly a kind of use for laboratory Enteromorpha microcosmic brood body incubator.
Background technology
Green tide refers to the phenomenon (Hiraoka et al., 2003c) being caused coastwise being formed a slice greenbelt by green alga hyper-proliferatives such as Ulva, Enteromorpha, bristle Trentepohlia and Cladophoras.Worldwide, from North America, Europe, Asia be coastal to Oceania, all constantly has green tide to occur in recent years, cause increasingly serious negative effect to coastal ecology environment and Tourism Economy.2007-2014, China's Huanghai Sea continuous 8 years green damp disasters of outburst, impact scope is wide, and the duration is long, and biomass is huge.Wherein the maximum area that relates to reaches 60,000 square kilometres (2010), and maximum coverage area reaches 530 square kilometres (2011).Through qualification, Enteromorpha algae is the dominant species of green tide outburst.This shows, the outburst of green tide is relevant to the history of life of Enteromorpha, is also very necessary to Enteromorpha studies of the life histories.
The cultivation of current experiment desk research microcosmic brood body and observe main based on culture dish, beaker, conical flask be auxiliary.Culture dish is mainly used for observing spore release situation, Enteromorpha blade segment is cultivated in culture dish, adds VSE culture fluid, and the methods such as illumination stimulate impels it to diffuse spore, then is observed the situation of diffusing of spore by microscope, flagellum radical etc.But because culture dish itself is very short and small, the Enteromorpha total amount that can carry is very limited, is unfavorable for the cultivation of amount reproduction body.Simultaneously because the character of Enteromorpha cell wall itself is namely more at the hop count cut, when concentration is higher, cell wall can discharge inhibitory substance and hinder diffusing of spore, and what therefore culture dish was unfavorable for when demand trial of strength is many observation spore diffuses situation.Beaker is generally used for cultivating Enteromorpha microcosmic brood body, at the large beaker upper cover last layer preservative film of about 300 milliliters, to prevent the evaporation of seawater, may pour in beaker with the water sample of Enteromorpha microcosmic brood body and cultivate, and after Enteromorpha seedling grows, it observed and count.This training method compensate for the deficiency on capacity than culture dish, but is but not easy to observe.Beaker is excessive, with tweezers pinch get time also inconvenient, and preservative film can not reuse, and can not carry out its air-charging incubation to brood body.Preservative film rapid wear simultaneously, once damaged assorted algae will pollute brood body.In addition, be also unfavorable for that repeatedly carrying out sampling observes.Part Experiment room also utilizes conical flask to cultivate microcosmic brood body, but sample tap is too little, sampling and Counts and inconvenience thereof.
This patent provides the incubator of a kind of Enteromorpha microcosmic brood body, is used for the Early observation of the Reproductive development of Enteromorpha and research.
Summary of the invention
The technical problems to be solved in the utility model is to provide Enteromorpha microcosmic brood body incubator, and this incubator good permeability is easy to use, and ensure that the integrality of Enteromorpha brood body attachment base portion, avoids the pollution of other brood bodies.
For solving the problems of the technologies described above, realize by following technical scheme,

Described bowl cover is provided with the semi-circle shaped transparent thin slice identical with the radius of bowl cover, and the bottom of this thin slice is fixed on the centerline of bowl cover, and remainder can upwardly open;
Described bottom of cup is shelved with rectangle Enteromorpha brood body slide glass.
Wherein, described cup and bowl cover material are lucite.Light transmission is good, durable, non-friable.
Wherein, the thickness of described thin slice is 0.03-0.07mm.Phototaxis experiment can be carried out by under ironed for light-shielding sheet, and suitable sheet thickness, be conducive to chip sorption on bowl cover.
The material of described Enteromorpha brood body slide glass is glass, and the length of this Enteromorpha brood body slide glass is 1-3cm, and wide is 1-3cm, and thick is 0.1-0.5mm.Enteromorpha brood body anchors on the glass slide of bottom, and when observation, direct clamping parts slide is placed on slide, neither pollutes other brood body, also ensure that the integrality of brood body attachment base portion simultaneously.
The lid limit of described bowl cover is provided with semiorbicular slot with thin slice corresponding section, when being convenient to carry out phototaxis experiment, light-shielding sheet is rolled into semicircle shape, poor from top to bottom in slot, the half of cup is all carried out shading treatment.
Compared with prior art, the utility model has the advantages that: 1, described Enteromorpha microcosmic brood body incubator is up big and down small bowl structure, is convenient to taking of algae, and can clear view to the germinating of the very high Enteromorpha spore count of density.2, the bowl cover difficult drop-off be threaded described in, ensure that mobile incubator formula, the culture fluid in cup can not be splashed away.3, bowl cover is provided with that ventilation closing lid is convenient carries out supplementing of nutritive salt and inflation to brood body, and the used time can not close, and makes microcosmic brood body by the pollution of assorted algae, and easy to use.4, described Enteromorpha microcosmic brood body is attached on the glass slide of bottom, and when observation, direct clamping parts slide is placed on slide, neither pollutes other brood body, also ensure that the integrality of brood body attachment base portion, and it is very convenient to take simultaneously.
