2The assay method of compensation point is the control valve of opening on the glass soda lime pipe, according to CO
2Molecular mass is greater than the principle of air quality, the CO in the photosynthetic chamber
2Concentrate to the bottom, carry out circular response, CO by glass soda lime pipe then
2Concentration reduces gradually, when being reduced to the concentration that needs, valve-off, but in this process the situation of change of the photosynthetic indoor carbon dioxide concentration of dense carbon dioxide kilsyth basalt accurate response; The assay method of crop drought resistance performance is the control valve of opening on the glass silicone tube; According to the principle of hydrone quality less than air quality, water vapour is concentrated to the top in the photosynthetic chamber, carry out circular response by the glass silicone tube then, water vapour is by silica gel absorption, photosynthetic indoor humidity reduces gradually, when being reduced to the humidity that needs, valve-off, but in this process the situation of change of the photosynthetic indoor humidity of psychrometer accurate response.
Road wheel is equipped with around the bottom in the photosynthetic chamber of described glass, plays the purpose that can arbitrarily move, and brings convenience for people use.
The interface of described pipeline and the photosynthetic chamber of glass seals by fluid sealant, guarantees photosynthetic indoor air-tightness, improves the accuracy of qualification result.
Described pipeline is a rubber tube, and it is more convenient that it installs the location.
Compared with prior art, adopt structural design described in the utility model, collection control light, wet, the control CO of control
2Concentration can be carried out the batch of various crop variety source ecotype and identify and screening under the manual control condition in one, simple in structure, reasonable in design, qualification result accurately, fast, and is time saving and energy saving, can be widely used in crop varieties authenticate technology field in batches.
