Abstract
The utility model discloses measurement protecting equipment for a photosynthetic apparatus probe. The measurement protecting equipment comprises a transparent shield with an opening at the bottom, and the bottom edge of the side wall of the shield is provided with a semicircle in-place hole. The shield is of a rectangular structure and is formed by splicing multiple pieces of organic glass, so the structure is simple, the processing is easy, and the cost is lower. A leaf chamber of a measurement probe is separated into an independent measurement space, thus the gas exchange between the leaf chamber and the external environment can be cutoff, and the stability and accuracy of measurement data are improved.
Description
Technical field
The utility model belongs to plant physiology vital measuring instrument field, is specifically related to a kind of measuring and protecting equipment of photosynthetic instrument probe.
Background technology
Photosynthesis is the process that green plants is chemical energy by the Conversion of Energy from the sun, is most important biological phenomena on the earth, is the key link that maintains material recycle on the earth, is also the deciding factor that crop yield forms.In the research work such as plant physiology, ecology, crop cultivation, thremmatology, often need to measure photosynthetic rate.Photosynthetic instrument is a kind of for measuring the important instrument of the Physiological Activities of Plants parameters such as plant leaf blade photosynthesis, transpiration and respiration.
Existing photosynthetic instrument is mainly comprised of parts such as main frame and measuring sondes, the portable photosynthetic instrument of CIRAS-2 of YiPP Systems company exploitation is example, this photosynthetic instrument mainly comprises main frame and measuring sonde (being called again leaf chamber), wherein between measuring sonde and main frame, by stube cable, be connected, measuring sonde is for gathering the photosynthetic signal of leaf houseplant blade, stube cable is sent to main frame by the photosynthetic signal of measuring sonde collection, then main frame is analyzed photosynthetic signal, exports corresponding data.The portable photosynthetic instrument of CIRAS-2 can be measured plant leaf blade and organize the parameters such as photosynthetic rate, respiratory rate, transpiration rate, stomatal conductance and soil CO2/H2O flux, can control intensity of illumination, humiture, atmosphere CO 2 concentration etc., both can measure under field conditions (factors), also can under manual control condition, measure.
While using this photosynthetic instrument to measure, operating personnel mainly measure by hand-held monitoring probe, the leaf chamber of measuring sonde is an independently measurement space, there is not gas exchange with the outer peripheral environment in leaf chamber, because stability and the accuracy of the residing atmospheric environment of measuring sonde and measurement data are closely related, preferably calm dustless during measurement, can control to greatest extent like this impact that the indoor blade-section of leaf is not subject to outside air air-flow and the particle that drifts along, thereby guarantee measurement data accurately.When yet reality is used particularly field survey, photosynthetic instrument is conventionally in having wind or having the environment of dirt, and this may directly cause the inaccurate or misdata of measurement data.Therefore, need the opertaing device of a kind of photosynthetic instrument probe measurement environment of exploitation badly, realize the Measurement accuracy of photosynthetic instrument.
Utility model content
Required independently measurement space while measuring for setting up photosynthetic instrument, this practicality provides a kind of measuring and protecting equipment for photosynthetic instrument probe simple in structure, portable, to guarantee stability and the accuracy of measurement data.
A measuring and protecting equipment for photosynthetic instrument probe, comprises the transparence protective cover that bottom is open, and at the bottom of the sidewall of described protective cover, edge has semicircular place hole.
When protective cover of the present utility model is used, directly lid is located on plant leaf blade to be measured, then can utilize photosynthetic instrument directly to measure plant leaf blade and organize the parameters such as photosynthetic rate, respiratory rate, transpiration rate, stomatal conductance and soil CO2/H2O flux, therefore protective cover must have light transmission, can not affect the normal photosynthesis of plant leaf blade or tissue.
During measurement, the inner leaf chamber that forms of protective cover, there is not gas exchange in this leaf chamber and outer peripheral environment, and it is indoor that measuring sonde can go deep into leaf by place hole, to gather every measurement data.For guaranteeing the sealing of leaf chamber, the technical program is made as semicircle by place hole, and place hole is buckled on the cable that measuring sonde leads to main frame, makes leaf chamber form a good closed environment.Because the measuring sonde leaf chamber under airtight condition can stop outside air, flow and the impact of floating dust particle on leaf Indoor measurement blade, therefore use this equipment to carry out Measurement accuracy to plant photosynthetic rate.
As preferably, described protective cover is dome-type structure.
The protective cover structure that can be formed in one, its shape has plurality of optional, for example: dome-type, class ball-type or other are irregularly shaped, be preferably dome-type, be convenient to processing, manufacture.
As preferably, described protective cover is tempered glass material.
Consider field survey and carrying convenience, protective cover must have enough toughness, and is difficult for while being collided brokenly, therefore, can select tempered glass material; For taking into account carrying convenience, must rationally control the thickness of tempered glass, make the Weight control of whole protective cover within the zone of reasonableness that can bear.
As preferably, described protective cover is rectangular configuration.
The structure of protective cover can also be rectangle, and the protective cover of rectangle can be structure as a whole, also can be spliced by polylith side plate,
As preferably, the material of described protective cover is organic glass.
On the basis that is rectangular configuration at protective cover, the utility model is orientated the material of protective cover as organic glass, organic glass has good toughness and anticollision performance, and simultaneously light transmission also meets the requirement of measuring, and also reasonable opertaing device cost of cheap material.
As preferably, the diameter of described place hole is 2cm.
When measuring, place hole coordinates with cable outside surface, reaches the object of sealing leaf chamber, therefore, the size of place hole and the diameter of optical cable are closely related, should carry out according to the size of optical cable the diameter of reasonable disposition place hole, generally, the diameter control of place hole is in the scope of 1.8-2.5cm.
As preferably, the end of described protective cover, is along with rubber weather strip.
The rubber weather strip arranging can further promote the sealing effectiveness of protective cover, and sealing strip can also be for being enclosed within the rubber sleeve on edge at the bottom of protective cover.
The utility model is simple in structure, practical, cost of manufacture is lower; The leaf chamber of measuring sonde is divided into an independently measurement space, and the gas exchange of isolated leaf chamber and external environment, to promote stability and the accuracy of measurement data.
Accompanying drawing explanation
Fig. 1 is the structural representation of the measuring and protecting equipment of the photosynthetic instrument probe of the utility model.
Embodiment
