Description
Technical field
It the utility model is related to a kind of field top-open type CO2Concentration and moisture control experiment gas cell device, belong to ecological
Or the field trial studying technological domain such as agronomy, it is related specifically to the whole world change factor (such as CO2Concentration, precipitation etc.) field control
The device of experiment.
Background technology
In the last hundred years, over particularly near twenty or thirty year, earth system is just experiencing global significant changes, and mankind's activity is led
The Atmospheric CO of cause2Concentration increase, Precipitation pattern change have been undisputable facts.Climate change is to the side of whole mankind's life
Aspect face all produces important influence.Atmospheric CO2Concentration rise, the change of Precipitation pattern are two important sides of whole world change
Face.Plant is to CO2Concentration and moisture are again extremely sensitive, are two key factors for influenceing plant growth, yield and quality.It is out of office
Simulated atmosphere CO simultaneously is wanted outside2The interactive devices of various global changed factor such as concentration rise, arid and precipitation enhancement are very
It is difficult.Both at home and abroad on field control experimental simulation CO2The elevated research device of concentration mainly has open top type air chamber (Open Top
Chamber, OTC) and free atmosphere formula device (Free Air CO2Enrichment, FACE) 2 kinds of experimental provisions.FACE devices
Equipment manufacturing cost is expensive, maintenance and CO2Consumption costs is very high, although other environmental variances inside and outside control area can be kept consistent,
CO2Control accuracy wind-engaging etc. influence, be unable to reach it is very high-precision, the country only have application in rice crop, high cost also causes very
Difficulty widely uses.Comparatively, OTC devices are more economical controllable, mostly straight tube cylindricality or polygonal frame, and locular wall is saturating using height

Embodiment
With reference to the accompanying drawings and examples, the technical solution of the utility model is described further.
A kind of field top-open type CO of the utility model2Concentration and moisture control experiment gas cell device, using open top type air chamber
(OTC) structure, on the one hand ensure that the environmental condition of plant growth approaches with extraneous physical condition, on the other hand compared with FACE (Free
Air Carbon-dioxide Enrichment) it is more economical controllable, air chamber frame structure is positive 8 face body, and each face is wide
1.55m, high 1.7m, the high 0.5m in inclined-plane, total height 2.9m, floor space 11.6m2, air chamber ground uses 8 pin column mixed muds
Fixation is poured, for supporting stationary frame structure, while reduces and surrounding environment is disturbed, and do not hinder the soil water inside and outside air chamber
Point, nutrient fully circulates exchange.All material uses the extraordinary glass of translucency, plenum interior without using any support,
To reduce influence and the maximum transmission to plenum space.The domestic device for carrying out top-open type gas control can not solve at present
The certainly uneven influence of precipitation in air chamber, and our device global design not only considers CO2Gas accurately controls, using top
The small design that closes up, the effect of gather qi together is played, to reach the purpose for saving gas consumption, small opening uses 45 degree of brace oblique angle
The method of layback is fixed, it is also contemplated that air chamber structure causes uneven influence to rainfall, by top-open type top distance
40~60cm highly locates, and the rain-proof shed gear of increase taper top removes external rainfall, is uniformly added to by monitoring rainfall in air chamber, and
Further contemplate the tolerance that field uses, the especially long-term durability such as anti-strong wind simultaneously.Wind in Inner Mongolian grassland is very frequently
Very big, we are overarched base using bar construction, add a circular base, circular base diameter and octahedra glass by 8 reinforcing bars
Glass device internal diameter is consistent, is capped the very high plastic sheeting of light transmittance above, uses most thin iron wire woven mesh on a plastic film
Structure, mesh is larger, play i.e. stabilizing films will not because of bottom or sidepiece wind effect and on turn over, the also printing opacity of maximum area.
Finally rain-proof shed be placed on 8 long columns of the face body of glass 8 is fixed, apart from open top type air chamber opening 50cm, then kept off the rain
Canopy can play the stable effect kept off the rain and be not in the light, and fully integrated with whole bottom, increase stability.
Below in conjunction with the accompanying drawings, the concrete structure of embodiment is described in detail：As shown in figure 1, the main body of the experimental provision is top

Support stationary frame structure；
The top of air chamber is provided with open ports 4, and the open ports 4 are designed for small close up, and the oblique angle 45 of brace 3 is used at small closing in
The method of degree layback is fixed；
At air chamber extended distance 40~60cm height, increase taper top rain-proof shed 14, be fixed on octahedra frame structure
8 long main frame columns 2 on the junction of top open ports brace 3；
As shown in Fig. 2 the rain-proof shed arch base for bar construction of taper top, is by 8 reinforced bar support frameworks 1 plus one
Cup dolly 17 forms, and cup dolly diameter is consistent with the internal diameter of octahedra framework, is capped the very high light-transmissive film of light transmittance above
15；Most thin rope or iron wire woven mesh structure are used on light-transmissive film, mesh is larger, as anti-wind net 16, plays i.e. stable
Film will not because of bottom or sidepiece wind effect and on turn over, the also printing opacity of maximum area.
It is the U-type groove consistent with octahedra frame base diameter to cut rain groove, is divided into 2 up and down：The upper rain groove that cuts is fixed on gear
On awning cup dolly, from upper section terminad of rain groove initiating terminal 5, low-angle is tilted down successively, and a rain groove end is cut as upper in Fig. 1
And opening 6；Rain and cut a groove and be fixed on air chamber base, incline direction is with upper section rain groove on the contrary, cutting groove end 11 successively from raining
Tilted down to initiating terminal low-angle, i.e., it is introduced below to connect in rain container such as rain section groove initiating terminal and the opening 10 in Fig. 1,
As being connected in Fig. 1 by connecing rain container and the rainy connected pipeline 12 of a groove starting end opening that cuts.
