Wherein co2Concentration tester 5 is testo-535 type co2Tester, this instrument can be used to monitor instant co2Concentration and Co in a short time2The change of concentration, measurable co2Concentration range is 0 9999ppm, makes monitoring convenient.
Automatic lifting machine controller 16 is used for adjusting the height of static camera-lucida 1, is not required to artificial superposition it is only necessary to operation is controlled Automatic lifting machine controller 16 processed controls the lifting of elevator, and is provided with main power controlling switch 17, controls co2Flux Recorder display screen 13, co2The keying of tester controller 14, top cover controlling switch 15 and automatic lifting machine controller 16, makes Must operate safer, it is to avoid potential safety hazard.
Idiographic flow: as shown in fig. 6, the static camera-lucida 1 of fit is arranged on the stainless steel base 6 of monitoring point, according to Requirement of experiment, adjusts the height of static camera-lucida 1 fit using escalator.The height often saving static camera-lucida 1 is fixed, according to set The total height to control static camera-lucida 1 for static camera-lucida 1 joint number closed, a height of 0.5m of the static camera-lucida 1 of such as one section, if will control The height of 1m is it is necessary to have static camera-lucida 1, by that analogy using the two high 0.5m of section.
After installing static camera-lucida 1, escalator is fixed on outside static camera-lucida 1, quiet by fixing handle adjusting The height of state camera-lucida 1.Open main power controlling switch 17, control the adjustable height of static camera-lucida 1, after reaching certain altitude, use ring Hoop 9 is enclosed within outside static camera-lucida 1, then is supported with aluminium alloy arm 2.Controlled by the top cover controlling switch 15 in master control device 12 Top cover 8 is closed, and monitoring starts.
Meanwhile, the fan 3 in static camera-lucida 1 is opened, so that the gas in case is uniformly mixed.
In monitoring, co2Concentration tester 5 passes through transmission cable 7 and co2Flux monitor display screen 13 is connected, can be automatic Continue to monitor the co in static camera-lucida 12Concentration, and by adjusting co2Tester controller 14 come control data output frequency and when Between be spaced.
In daily continuing to monitor, often static camera-lucida 1 can be put down by monitoring 15min, is easy to static camera-lucida 1 and air Gas exchange is it is ensured that the normal growth of crop.Each observation time length can be adjusted according to research requirement.
When observation terminates, disconnect co2Concentration tester 5 and co2Transmission cable 7 between flux monitor display screen 13, passes through Master control device 12 controls the top cover 8 in static chamber 1 to open, and is put down static camera-lucida 1 using escalator, is again linked in Together, system replys original observer state.
This system, by the regulation and control to static camera-lucida height, does not affect other natural environment of plant growth in static chamber. There is easy to operate, sustainable monitoring, portable and easy-to-assemble feature, can be used for monitoring crop different high in different growing stages Farmland ecosystem co under the conditions of degree2The research of flux discharge.Cooperation automatic weather station etc. can be used for long-term field agricultural ecological Systematic research works.Set up static camera-lucida how simultaneously, and how the static camera-lucida by is both connected to co2Monitoring device, Realize the monitoring that many places continue simultaneously.
Although being described in detail to the specific embodiment of invention in conjunction with accompanying drawing, should not be construed as to this patent Protection domain restriction.In scope described by claims, those skilled in the art are without creative work The various modifications made and deformation still belong to the protection domain of this patent.
