Description
Technical field
The utility model relates to experimental facilities, especially a kind of whole strain group training seedling photosynthetic rate rapid determination device.
Background technology
Photosynthetic rate refers to the speed of plant stabilizing carbon dioxide, i.e. the carbon dioxide fixation of unit interval unit leaf area (or oxygen release) amount.Study whole strain plant tissue culture seedling photosynthetic rate under the condition that controls environment, to improvement group training environment, adjustment culture medium prescription, batch production is produced the healthy and strong training seedling of organizing and is used for agricultural production, and the survival rate after raising group training transplantation of seedlings is significant.Mostly currently used photosyntometer is to measure fraction area (about 6cm on individual blade
2) photosynthetic rate, but a lot of requirement of experiment is measured whole strain group training seedling photosynthetic rate in culture flask, and needs the photosynthetic rate under the same plant different times of replication, different illumination intensity and gas concentration lwevel condition.Based on such requirement, be necessary to find a kind of fast, the device and method of the whole strain group training of precise determination seedling photosynthetic rate.
Summary of the invention
The purpose of this utility model is: a kind of whole strain group training seedling photosynthetic rate rapid determination device is provided, it can be realized the Quick Measuring of the photosynthetic rate of whole strain group training seedling, can show in real time intuitively that plant is in the photosynthetic rate not being subject under any mechanical pressure degree of impairment, and can measure arbitrarily the photosynthetic rate of individual plant or whole bottle (colony) group training seedling.
The utility model is achieved in that whole strain group training seedling photosynthetic rate rapid determination device, comprise the IRGA sample chamber of plant photosynthesis analyzer, soil leaf chamber installing plate, RGA sample chamber and soil leaf chamber installing plate composition complex, separately be provided with a transparent self-control leaf chamber, the top of self-control leaf chamber is movable cover structure, on self-control leaf chamber, is provided with fixed orifice, pore and recirculatory pipe interface; Self-control leaf chamber is connected with soil leaf chamber installing plate by fixed orifice, makes by oneself between leaf chamber and complex as rigid seal is connected; RGA sample chamber is connected with photosynthetic instrument main frame by data line.
The volume of self-control leaf chamber is more than 2L.
Owing to having adopted technique scheme, compared with prior art, the utility model improves existing employing plant photosynthesis analyzer, adopt self-control leaf chamber to substitute standard leaf chamber, whole strain group training seedling can be placed in to self-control leaf is indoor together with nutrient culture media and measure, photosynthetic instrument can show that plant is in the photosynthetic rate not being subject under any mechanical pressure degree of impairment intuitively in real time, and can measure arbitrarily the photosynthetic rate of individual plant or whole bottle (colony) group training seedling; The standard leaf chamber that has also solved existing plant photosynthesis analyzer cannot be measured area and be less than 6cm
2the difficult problem of individual blade; Photosynthetic instrument after repacking can be measured the whole strain photosynthetic rate under different illumination intensity and gas concentration lwevel condition; Calculate the principle of work of photosynthetic rate according to sample chamber and reference cell carbon dioxide gas scale of construction difference according to plant photosynthesis analyzer, physical dimension also can be measured in the respiration of fruits speed being applicable in scope in self-control leaf chamber.

Embodiment
Embodiment of the present utility model: the structure of whole strain group training seedling photosynthetic rate rapid determination device as shown in Figure 1, by the standard leaf chamber of the photosynthetic instrument of LI-6400XT and IRGA sample chamber cap from removing from trivial handle, then taking the soil leaf chamber installing plate 2 of LI-6400XT as bridge, the IRGA sample chamber of LI-6400XT 1 is connected to 3 with the self-control leaf chamber of making by transparent resin material to be connected together, be fixed on soil leaf chamber installing plate 2 by fixed screw and rubber washer, make IRGA sample chamber 1 and self-control leaf chamber 3 form the gun iron link of sealing; In manufacturing process, the top of self-control leaf chamber 3 is made as to movable cover structure, on self-control leaf chamber 3, be provided with fixed orifice 4, pore 5 and recirculatory pipe interface 6; Self-control leaf chamber 3 is connected with soil leaf chamber installing plate 2 by fixed orifice 4, makes by oneself between leaf chamber 3 and complex as rigid seal is connected; RGA sample chamber 1 is connected with photosynthetic instrument main frame 8 by data line 7; Self-control leaf chamber 3 is the container of a cuboid, and physical dimension is 20cm × 10cm × 10cm.
The aperture of fixed orifice 4 is determined by bought screw diameter; The aperture of pore 5 is determined by the pore external diameter on installing plate; The aperture of recirculatory pipe interface is determined by recirculatory pipe external diameter.
Whole strain group training seedling photosynthetic rate method for quick, whole strain group training seedling and nutrient culture media thereof are together put into self-control leaf chamber 3, in matching process, air is mixed to fan and close, the inspection work before preheating and after preheating and the mensuration of photosynthetic rate all operate by the operation instructions of LI-6400XT.
Taking " measuring process of the non-condition that controls environment " as example:
Install chemicals, connect hardware (if use CF card, insert after main frame and fix in sulculus).Start, configuration interface is selected Factory default, and connection status, by " Y ", enters master menu, the about 20min of preheating.
Carry out current check, note: when band nutrient culture media mensuration group training seedling photosynthetic rate is carried out matching operation, need close air and mix fan, and mix fan without closing air when measuring respiration of fruits speed and carrying out matching operation.
Open self-control leaf chamber 3, put group training seedling or fruit into.
By 1, F1(Open Log File), the position (main frame or CF card) that selection deposits data in, creates a file, and enter, inputs a remark, enter.
Wait for that a line parameter is stable, the capable Δ CO2 of b value fluctuation <0.2 μ molmol
-1, Photo parameter stability after radix point one; C line parameter is (0<Cond <1, Ci>0, Tr>0) in normal range, by F1 (Log) record data.
Change and measure sample, by F4, add remark, repeat [0012-0014] step, measure.While changing sample, need mate.
Press F3(Close file), save data file.
With RS-232 data line connection computer and LI-6400XT, return main interface by esc, by F5(Utility Menu), select " File Exchange Mode " by upper and lower arrow, SimFX software is installed on computers in advance, is double-clicked and open LI6400FileEx, click File, select Prefs, select Com port, by Connect, after successful connection, select File is transferred to assigned address (data in CF card also can exit after card, directly insert computer card reader and carry out derived data).
Press esc, return main interface, shutdown.
Relaxed state in the middle of chemical tube knob is threaded to; Pivoting leaf chamber fixed screw, keeps leaf chamber in open mode.
