Fig. 1 is the structural representation of existing determinator.
Fig. 2 is structural representation of the present utility model.
In accompanying drawing, 1 represents lower house, and 2 represent upper shell, and 3 represent soil breaking tool, and 4 represent fan, and 5 represent plant to be determined
Or plant population, 6 represent soil, and 7 represent locating ring, and 8 represent photosynthesis tester.
Detailed description of the invention
With specific embodiment, this utility model is elaborated below in conjunction with the accompanying drawings:
Specific embodiment, as in figure 2 it is shown, whole plant or plant population photosynthesis measurement device, including housing and light
Cooperation tester 8, case cover is peripheral plant to be determined or plant population 5 and fixing with soil 6 to be connected, and photosynthesis is tested
The measurement end of instrument 8 connects with enclosure interior, and housing includes the transparent plastic upper shell 2 of cylindrical metal lower house 1 and bottom opening,
Upper shell 2 lower surface is provided with locating ring downwardly projecting, that internal diameter is less than upper shell 2 external diameter more than upper shell 2 internal diameter and external diameter
7, lower house 1 upper surface is provided with locating slot, and locating ring 7 seals with locating slot grafting, lower house 1 lower end insert soil internal with
Zinc fractions dense block tight fit.The wall thickness of locating ring 7 is 1:(2～4 with the ratio of the wall thickness of upper shell 2), ensureing locating ring 7
Have sufficient intensity can reliably grafting location on the premise of, it is possible to reduce material usage, cost-effective.Locating ring 7 and upper casing
Body 2 is integral type structure, it is to avoid the generation of seam crossing crack conditions so that connect more solid and reliable.Lower house 1 and upper shell
This plug-in mounting structure of 2 can simultaneously work as the effect of locking positioning and sealing, and location more accurately and reliably, does not haves dislocation
Phenomenon.Plant to be determined or plant population 5 can carry out photosynthesis by upper shell 2, it is not necessary to seal with soil, save
Water and the process of mud, time saving and energy saving, and good sealing effect, improve the accuracy of measurement result.
As to further improvement of the utility model, lower house 1 lower surface is fixed with one group of soil breaking tool 3, soil breaking tool 3 times
End is spininess, the most more easily lower house 1 lower end can be inserted soil.
As to further improvement of the utility model, lower house 1 inwall is fixed with fan 4, makes the air in housing
Flow, make oxygen produced by plant to be determined or plant population 5 photosynthesis and carbon dioxide distribution more uniform, can
To improve the accuracy of measurement result.
