Abstract
The invention relates to a testing device for plant photosynthesis, which is characterized in that a cultivation disk body and a transparent sealed cover which is covered inversely in the cultivation disk body are included. The bottom part of the cultivation disk body is provided with culture fluid which is fit for the water closing of the transparent sealed cover; the culture fluid in the sealed cover is laid with a water absorption material layer; the upper surface of the water absorption material layer is laid with plant culture substrate. Firstly, the testing device is composed of the culture disk and the sealed cover to form a micro sealed chamber, the plant culture fluid acts as the water closing of the sealed cover, and the reliability of the sealing is good. Secondly, the environmental factors influencing on the plant photosynthesis effect in the sealed chamber are effectively controlled automatically, so as to be benefit for the test of plant photosynthesis (for example, the synchronous test can be completed by setting different chamber atmospheric environment factors by a plurality of devices). Finally, the plant culture substrate in the sealed chamber obtains the plant nutrition by the water absorption materials, the substrate (medium) can fit for different varieties of plants, including the plants with different plant heights or in different growing times.
Description
Technical field:
The present invention relates to a kind of experimental rig, be specially adapted to the experimental rig of the photosynthesis of plant in the space research.
Background technology:
The assay method of photosynthesis of plant and device are a lot, but to the experimental rig that is used for space research seldom, and this most experimental rig only pays attention to the test of individuality, and be very few to the test of colony.
Summary of the invention:
The object of the present invention is to provide a kind of tester for photosynthesis of plant, this device can carry out testing experiment at plant population, and test result more can reflect the photosynthetic effect of plant population exactly.
The present invention is achieved through the following technical solutions:
Tester for photosynthesis of plant of the present invention, it is characterized in that: comprise and culture disk body and tip upside down on the transparent enclosed hood of culturing in the disk body, the culture fluid in order to transparent enclosed hood water seal is equipped with in described breed disk body bottom, be equipped with absorbent material layer in the culture fluid in the enclosed hood, the absorbent material layer upper surface is equipped with plant cultivation media.
The present invention at first is made of culturing disk and enclosed hood, forms miniature closed cabin, utilizes the watertight of plant culture fluid as enclosed hood, airtight good reliability; Secondly the envirment factor that influences the photosynthesis of plant effect in closed cabin obtains control effectively automatically, and this is to carrying out photosynthesis of plants test very favourable (for example, can different cabin atmosphere envirment factors be set by many table apparatus and finish simultaneous test); Closed cabin implants cultivation matrix is to obtain plant nutrition by absorbent material, and this matrix (medium) can adapt to the plant of different cultivars, comprises the plant of different plant heights or different growing.
Description of drawings:
Fig. 1 is an organigram of the present invention.
Embodiment:
Tester for photosynthesis of plant of the present invention, tester for photosynthesis of plant, comprise and culture disk body 1 and tip upside down on the transparent enclosed hood 3 of culturing in the disk body, the culture fluid 2 in order to transparent enclosed hood 3 water seals is equipped with in described breed disk body bottom, be equipped with absorbent material layer 4 in the culture fluid in the enclosed hood, the absorbent material layer upper surface is equipped with plant cultivation media 5, plant cultivation media 5 frames are located on the aluminum alloy frame 9 on the absorbent material layer, and culturing disk 1 and enclosed hood 3 are respectively to be made by stainless steel and glass.
In order to adapt to the needs of different plant growings, absorbent material layer 4 upper surfaces exceed cultivates liquid level 2-10mm.
For the ease of carrying out various tests, enclosed hood 3 is provided with intake interface 6 and instrument connection 7.
Above-mentioned breed disk body top is provided with artificial light source 8, and the height and position of artificial light source is adjustable, and the artificial light source top is provided with reflective mirror 10.
Stainless steel culturing disk of the present invention and glass enclosed hood by the watertight of plant culture fluid, form miniature closed cabin.In closed cabin, plant cultivation media is fixed in the aluminum alloy frame, places the top of absorbent material, and high water-yielding stratum 2-10mm.Inside dimension is effective plant cultivation area in the aluminum alloy frame.Artificial light source directly over the closed cabin is a some T4 fluorescent lamp.The intensity of illumination of plant surface can be set according to the requirement that different tests is handled, and also can realize by the distance H of adjusting light source to plant surface.The photoperiod of artificial light source also is adjustable, by the test requirements document procedure auto-control.Instrument connection 7 and intake interface 6 that closed cabin is provided with, intake interface 6 and CO
2The input device connects, CO
2Addition also can be controlled automatically by test requirements document.
