Description
Technical field
The utility model is suitable for a kind of device measuring water phytoplankton respiratory rate and primary productivity, specifically relates to
And a kind of device measuring Dissolved Oxygen in Water using light and dark bottle technique.
Background technology
Primary productivity is the amount of autotroph synthesis of organic substance matter in unit interval, unit space.Phytoplankton is
First link of aquatic food chain, primary productivity are the bases of aqueous bio productivity, and the height of productivity decides
Substance cycle in reservoir and energy flow situation.The height of primary production of phytoplankton is the weight for evaluating water pollution situation
Biological indicator is wanted, the monitoring to primary productivity can be very good the growing state and the prediction that reflect existing phytoplankton
The possibility that wawter bloom occurs.Measurement most conventional methods to primary productivity are black and white bottle oximetries.
Existing black and white bottle oximetry is usually that the fixed depth of water 24 of the black and white bottle of dissolved oxygen bottle or wide-mouth bottle placement is small
Black and white bottle is lifted and then fixes oxygen in water using the method for adding medicine of uncapping by Shi Hou.Publication No. CN201364332
, CN202372498 U, the above-mentioned experimental method being all made of in the Chinese utility model patents such as CN206497109 U and black and white bottle
Model.But when measuring in this way, phytoplankton enters a new environment（Enter in bottle from open waters）One is needed to adapt to newly
The time of environment could restore original production status.Inadequate phytoplankton adapts to new environment within 24 hours, so that measuring
Primary productivity it is relatively low；And need to uncap after dissolved oxygen bottle or wide-mouth bottle end exposure and medicament fixation dissolved oxygen is added dropwise, this
Sample is inevitably swapped with the oxygen in air so that extra oxygen is spilt into air in the high white bottle of dissolved oxygen, empty
Oxygen in gas mixes in the black bottle of low dissolved oxygen so that measured value is much smaller than actual value.In addition, instruments weight is relatively light and bottom does not have
Have fixing bracket, may be tilted during being deposited to river bed, once and bottom have hard or sharp objects that can damage
Instrument greatly reduces the service life of instrument.
Utility model content
The technical problem to be solved by the utility model is to provide light and dark bottle techniques to survey water phytoplankton Primary Production in water
The device of power hung and took bottle for a cycle by original 24 hours and is changed to 48 hours, test proves that, what is measured within 48 hours is first
Grade productivity is closer to actual value, if pressing pervious 24 hours, phytoplankton needs to adapt to new environment, so that measure
Primary productivity is relatively low；If the time is more than 48 hours, phytoplankton can be because closed space, which lacks nutritive salt, be suppressed life
It grows and deviates true production level.From experimental precision, using the saline bottle with anti-mouth rubber stopper, pass through the side of injection
Formula injects medicament without uncapping and fixes oxygen, greatly improves experimental precision, and saline bottle reduce experiment at
This.This, which has device also, has light, the easy to operate advantage of equipment, can protective device to greatest extent, raising utilization rate.
In order to realize above-mentioned technical characteristic, what the purpose of this utility model was realized in：Light and dark bottle technique surveys water in water
The device of body primary production of phytoplankton, it includes connecting bracket, and the both sides of the connecting bracket are equipped with bottling frame, described
The opening of bottling frame is closed by fixing bolt；Link is installed at the top of the connecting bracket, in the front side wall of connecting bracket
Upper fixation is equipped with thermometer, the bottom of the connecting bracket is equipped with gravity drop hammer holder, institute there are two card slot on the card slot
It states and gravity drop hammer is installed on gravity drop hammer holder.
The connecting bracket uses decussate texture, and is made of stainless steel.
Saline bottle black and white bottle is placed with inside the bottling frame, the bottleneck of the saline bottle black and white bottle uses anti-mouth rubber
Leather plug seals.
The saline bottle black and white bottle uses syringe and syringe needle to its internal injection experiments reagent.
The experimental period of device is 48 hours.
The utility model has the advantages that：
1, light and dark bottle technique provided by the utility model surveys the device of water phytoplankton primary productivity in water, passes through experiment
The improvement in period hung and took bottle for a cycle by original 24 hours and is changed to 48 hours, more meets experiment demand and experiment is accurate
Degree.
2, the black and white bottle of dissolved oxygen bottle or wide-mouth bottle is substituted for the black and white bottle of saline bottle, the side of injection can be passed through
Formula injects medicament without uncapping and fixes oxygen, greatly improves experimental precision.
3, design bottling frame mounting and fixing bracket and gravity drop hammer, anti-locking apparatus can be deposited to river bed in connecting bracket
During run-off the straight.
4, above-mentioned apparatus has light, easy to operate advantage.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the saline bottle black and white bottle structure schematic diagram of the utility model.
Fig. 3 is the syringe construction schematic diagram of the utility model.
In figure：Connecting bracket 1, bottling frame 2, fixing bolt 3, link 4, card slot 5, thermometer 6, gravity drop hammer 7, gravity drop hammer branch
Frame 8, saline bottle black and white bottle 9, anti-mouth rubber stopper 10, syringe 11, syringe needle 12.
Specific implementation mode
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
As shown in Figs. 1-3, light and dark bottle technique surveys the device of water phytoplankton primary productivity in water, it is characterised in that：It
