Background technology
Photosynthesis is that green plants utilizes the photosynthetic pigment such as chlorophyll and some bacterium (as being with the halophilic archaea of purple membrane) to utilize its cell itself, under the irradiation of visible ray, carbonic acid gas and water (bacterium is hydrogen sulphide and water) are converted into and store the organic matter of energy, and discharge the biochemical pathway of oxygen (bacterium release hydrogen), be also energy conversion process luminous energy being changed into chemical energy in organic matter simultaneously.For nearly all biology of biosphere, this process is the basis that they are depended on for existence, is also the important medium of earth carbon-oxygen equilibrium.
For higher plant, energy source only unique in whole photosynthesis, carbonic acid gas is then photosynthetic base stock.The relation of plant and light, carbon dioxide environment is the hot issue of plant physiology and plant ecology research always.
But, due to the not operability of external environmental condition, the different light of any combination and the stable environment condition of gas concentration lwevel can not be obtained, become the obstacle of photosynthesis of plant mechanism based research, constrain the Study on Ecophysiological Characteristics of Narrow of plant, light, carbonic acid gas, also limit in crop breeding and screen specular removal parent and improve the application studies such as grain yield.The present invention then provides device facility for addressing these problems.
Summary of the invention
The object of the invention is to provide illumination, temperature, humidity and a gas concentration lwevel controlled, environment is relatively stable, and can the climatic cabinate of remote monitoring, for a reliable and stable environmental condition is created in the physiological ecological relevant to photosynthesis of plant and application study.
Technical scheme of the present invention is, a kind of low concentration of carbon dioxide incubator of plant physiology basic scientific research, described incubator comprises the casing be made up of culturing room and the equipment installing zone with door body, wherein culturing room is divided into low concentration of carbon dioxide Yun Qi district by horizontally disposed homogenating plate and treats culture cultivation region
The output pipe exporting fresh air is provided with in low concentration of carbon dioxide Yun Qi district,
Treat to be provided with exhaust pipe in culture cultivation region, below homogenating plate, be provided with fluorescent lamp, sidewall is provided with indoor apparatus of air conditioner, object disposing platform is provided with humidifier, treating in culture cultivation region, to be also provided with gas concentration lwevel sensor and light, temperature, wet sensor
Be provided with without oil gas pump, absorption unit of dioxide carbon, compressor of air conditioner and the ECU with CPU in equipment installing zone,
Described exhaust pipe, to be communicated with successively with output pipe without oil gas pump, absorption unit of dioxide carbon, controlled end without oil gas pump is connected with ECU, and the controlled end of described indoor apparatus of air conditioner, compressor of air conditioner, humidifier and fluorescent lamp is all connected with ECU.
Long slot bore array is provided with in described homogenating plate.
The casing of described culturing room is organic transparent glass material.
The plant growing light supplement lamp coordinated with fluorescent lamp is also provided with below homogenating plate.
The invention still further relates to a kind of control method of incubator described above, described method is the threshold value of the temperature arranged in the CPU of ECU, humidity, illuminance and gas concentration lwevel, the temperature of culturing room controls compressor of air conditioner by CPU and indoor apparatus of air conditioner regulates, the humidity of culturing room controls humidifier by CPU and compressor of air conditioner, indoor apparatus of air conditioner regulate, the illuminance of culturing room controls fluorescent lamp by CPU and regulates, and the gas concentration lwevel of culturing room controls to regulate without oil gas pump by CPU.
Described temperature threshold controls at 5 ~ 35 DEG C.
Described humidity threshold controls 50% ~ 85%.
Described illuminance threshold value is according to treating that the growth cycle of culture carries out timing settings.
Described gas concentration lwevel threshold value controls at 0 ~ 2000ppm.
The present invention by gas-recycling plant by the air suction absorption unit of dioxide carbon in incubator, the concentration of carbonic acid gas in casing is reduced to reduced levels, the concentration of the carbonic acid gas in casing is maintained a more stable level by automaton and air mixing fan device simultaneously.
The invention has the beneficial effects as follows, by environmental conditions such as the illumination in control incubator and gas concentration lwevels, make photosynthetic about research can research institute need artificial concentration under carry out, and can the growth and development state of remote monitoring plant, thus to obtain reliable experimental data be photosynthesis of plant basic research, the application studies such as ecological study and breeding specular removal material evaluation and screening provide facility.
Accompanying drawing explanation
Fig. 1 is incubator structural representation of the present invention.
Embodiment
In the specific implementation, referring to Fig. 1, represented by dotted arrows signal of telecommunication connecting line, incubator is glass material, is convenient to observe inner case and have good light transmission in the present invention.Preferably select safety glass, intensity can be higher.Incubator is provided with seal door structure, article of conveniently taking.Lower margin moves mainly for facilitating incubator.
Described absorption unit of dioxide carbon 10 is a kind of filters that soda lime is housed.First plant or crops are put on object disposing platform 7.The numerical information of light, temperature, wet sensor 16 and gas concentration lwevel sensor 15 Real-time Collection intensity of illumination, temperature, humidity and gas concentration lwevel, the setting value of CPU in gas concentration lwevel is higher than ECU 12, so ECU 12 is opened and is bled without oil gas pump 9, carbonic acid gas in air exports ozone after absorption unit of dioxide carbon, so-called fresh air, the air of the low concentration of carbon dioxide namely after absorption unit of dioxide carbon filters.Fresh air can be sent into and treat culture cultivation region 2 after output pipe 14 and homogenating plate 4.Wherein homogenating plate 4 is for having array loose structure, fresh air can be sent into uniformly and treat culture cultivation region 2.While gas concentration lwevel controls, also intensity of illumination, temperature and humidity are controlled, by the open and close of ECU 12 pairs of fluorescent lamps 5 and plant growing light supplement lamp 17, can the controlled light time, plant growing light supplement lamp 17 can coordinate fluorescent lamp 5 to use simultaneously, avoids range of exposures uneven.The open and close of ECU 12 pairs of compressors of air conditioner 11 and indoor apparatus of air conditioner 6, can control temperature height and reduce air humidity.The open and close of ECU 12 pairs of humidifiers 8, can improve air humidity.By the scope of Comprehensive Control intensity of illumination, temperature, humidity and gas concentration lwevel, may be used for basic scientific research, realize the judgement of the photosynthetic efficiency to plant or crops.
Mini-fan 18 can compensate gas concentration lwevel.When gas concentration lwevel exceeds threshold value, now open without oil gas pump 9, mini-fan 18 is closed simultaneously, the gas concentration lwevel in air is reduced by absorption unit of dioxide carbon 10, when reaching gas concentration lwevel lowest threshold, close without oil gas pump 9, can open by Non-follow control mini-fan 18 afterwards, the design reasons of mini-fan 18 is when gas concentration lwevel is lower, treat that culture now also needs to carry out photosynthetic carbonic acid gas, therefore open mini-fan 18 conveying of the air in the external world to be come, and then realize can supplementing carbonic acid gas while absorbing carbon dioxide, realizing within a certain period of time can the effect of stability contorting gas concentration lwevel.
