Technical field
The present invention relates to plant smoke gas and coerce and gas concentration monitoring technical field, be specifically related to a kind of plant be carried out
PM2.5 smokes the experimental provision that gas is coerced.
Background technology
At present, enter the dust in air all over the world and be about 100,000,000 tons more than every year, account for six points of whole air pollutants
One of.And along with China's industrialization in the last few years, the developing rapidly of urbanization so that the pollution of particulate matter is the most serious.Granule
Thing particle diameter is the least, endangers the most serious.The particulate matter of aerodynamic equivalent diameter≤2.5 μm in surrounding air, i.e. fine particle,
Also it is PM2.5, due to sedimentation difficulty, coverage extensively, controls and difficulty of governance is big, become the focus of research.Plant passes through it
Pore on blade and the hole skin on branch, by atmosphere pollution suction body, in being carried out by oxidation-reduction process in vivo
With form innocuous substance (i.e. Degradation), or excreted by root system, or accumulation be stored in a certain organ.Plant from natural
Thing screens or cultivate super assimilation plant by genetic engineering means and the theoretical development with technology be modern later important and
There is the research work of application prospect.
More for the plant Effect study that lays the dust, but right in plant is entered with the form of PM2.5 for nitrogen oxides
Plant physiological processes is less to the research of the resistance mechanism of excess nitrogen oxide with the impact of blade construction and plant.Along with planting
Thing repairing environment pollutes the rise of technology, utilizes the assimilation of plants towards atmospheric pollution thing or super assimilative capacicy to carry out control atmosphere pollution
Become the new problem of frontier nature the most strengthened research and develop rapidly, and the research of this type of gas stress experiment is logical
Artificial fuming method often can be used to reach to test desirable effect.
Summary of the invention

In the fan ensureing that room air is homogeneous；Each test plant room upper surface and exhaustor are equipped with concentration monitor mouth；Each confession
The exhaustor connection alkaline absorption solution of examination plant room.
Described pipeline includes rubber hose and pvc pipe；Described pvc pipe connects each test plant room, soft by rubber
Pipe connection aerosol generator.
Described fan includes vertical fan and the horizontal fans of front surface being located at test plant indoor upper surface.Can leaf
The homogeneity of indoor institute supplied gas.
Described test plant room is no less than 4.Its number can be according to the floristics number selected by experiment and repeat number
Being adjusted, ranking method can be that Latin square adjusts or random district group.
Described vertical fan and the rotating speed of horizontal fans are 3500r/min.
Described vertical fan and the power supply of horizontal fans are aneroid battery or solaode.
Aerosol generator, model: TSI 9306A, carry air pump, the aerosol particle diameter sent is adjustable.
Concentration monitor mouth is easy to detect leaf indoor gas in real time, it is ensured that supply the accurate with homogeneous of gas testing bulk concentration.
Alkaline absorption solution can absorb excessive gas, it is ensured that environment innoxious.
Beneficial effect: compared with existing design, the present invention smokes the experiment dress that gas is coerced for plant carries out PM2.5
Put, aerosol generator provide gas, various types of plant is put into test plant indoor, the plant needing research is smoked
Gas disposal, carries out Experimental Research, and scientific height, systematic error are little, with strong points, the application high, easy to spread of environmental protection degree.For needing
The series of experiments such as PM2.5 Stress on Plant physiological process research to be carried out provide effective experimental provision, improve its data accurate
Degree, can effectively guarantee that smoked gas coerces produced impact effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of experimental provision.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
As shown in Figure 1.Plant is carried out PM2.5 and smokes the experimental provision that gas is coerced, for Latin square arrangement (or random district
Group) design.Experimental provision by aerosol generator (model: TSI 9306A, carries air pump, the aerosol particle diameter sent can
Adjust) 4 offer gas sources, with rubber hose 5 and the pvc pipe of a diameter of 16mm (pipe diameter size can be adjusted as the case may be)
Aerosol generator and volume size are 64dm by 63(the big I in test plant room makes corresponding adjustment according to plant size)
Test plant room 1 is connected, and plant is respectively placed in each test plant room.Each test plant room upper surface and exhaustor tail end are each
It is provided with a concentration monitor mouth 2, experimentation can measure plant indoor PM2.5 concentration at any time.Test plant indoor upper surface
Equipped with vertical fan 3-1, front surface is equipped with horizontal fans 3-2, it is ensured that (rotating speed is 3500r/ to the homogeneity of indoor gas
Min, can adjust accordingly, and power supply is aneroid battery or solaode).Exhaustor is passed through by many residual air in each test plant room
Body enters in alkaline absorption solution 7, absorbs excessive gas, it is ensured that surrounding enviroment innoxious.
Use said apparatus, carried out PM2.5 in Xia Shu forest farm, Jurong, industry and coerced dissimilar plant
The Experimental Research of physiological process impact.Select open smooth place, climing Changchun, little leaf boxwood, trachelospermum jasminoide, Herba Portulacae are put respectively
In each test plant room 1, use 50 μ g/m3(setting with reference to Nanjing the mean P M2.5 concentration) and 150 μ g/m3Two kinds of concentration
PM2.5 (composition: NaNO2) Four Plants carried out the most bimestrial smoked gas stress experiment.Now measure each concentration monitor mouth
Place's PM2.5 concentration and different confession try each plant Net Photosynthetic Rate value under concentration (every strain plant is surveyed and takes average three times).
Table 1 50 μ g/m3For PM2.5 concentration value unit at each concentration monitor mouth under examination concentration: μ g/m3
| For row room, room sequence number | First row | Secondary series | 3rd row | 4th row |
| The first row | 50.2 | 49.7 | 49.4 | 49.6 |
| Second row | 49.3 | 48.9 | 49.2 | 50.1 |
| The third line | 49.1 | 48.5 | 48.8 | 49.1 |
| Fourth line | 49.1 | 48.7 | 48.5 | 48.8 |
| Tail end | 48.9 | 48.1 | 48.0 | 48.7 |
From the data of table 1, the present invention smokes the experimental provision that gas is coerced, accuracy for plant is carried out PM2.5
Height, the actual concentrations value at each concentration monitor mouth, is allowing for examination concentration value, fluctuation range≤5% all close to gas source
Within range of error.This design can accurately carry out smoked gas stress experiment.
Table 2 little leaf boxwood coerces lower Net Photosynthetic Rate value in difference for examination concentration
As shown in Table 2, the smoking the experimental provision that gas coerces there is certain experiment for plant being carried out PM2.5 of the present invention
Effect, high concentration PM2.5 coerce under plant, its photosynthetic rate has had obvious increase, and the Fumication test life to plant is described
Reason process creates certain impact, and this experimental provision can operate with probe into that plant physiological processes affects by PM2.5 relevant and grinds
In studying carefully, there is certain reliability.
