Technical field
The present invention relates to field of agricultural production technologies, more specifically to one kind in agricultural production process
In used agricultural microclimate determine device.
Background technology
Agricultural microclimate refers to the physical process and biology between farmland onionskin atmosphere, soil layer and crop groups
The formed small range climatic environment of process interaction, often with the radiation in the onionskin atmosphere of farmland, air
The value of the agrometeorological elements such as temperature and humidity, wind, carbon dioxide and the soil moisture and humidity is represented.
Carbon dioxide content, humiture in agricultural microclimate are more basic testing indexs, right at present
The mensuration mode of field carbon dioxide and humiture is：The hand-held sensing equipment of measure personnel, field each
Walked up and down between measuring point measurement, carbon dioxide content detector and humiture are provided with sensing equipment
Detector, the whether suitable crop growth of agricultural microclimate is learnt by reading.
Although current mensuration mode can be derived that carbon dioxide content and the warm and humid number of degrees in agricultural microclimate
Value, but this kind of mensuration mode but has problems with：Due to needing measure personnel's hand in continuous mode
Holding equipment is walked about measurement in field, and this can make field gas stable state change, and gas stable state changes
Afterwards gas content and humiture will be caused to change, thus the number measured by this kind of metering system
It is worth and not accurate enough, measurement error is larger.
Therefore, how more accurately agricultural microclimate to be measured is current those skilled in the art
The technical problem of urgent need to resolve.
The content of the invention

Embodiment
The core of the present invention is that providing a kind of agricultural microclimate determines device, so as to more accurate
Agricultural microclimate is measured, so as to provide superior technique support for the stable high yield of crops.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the invention, and
The embodiment being not all of.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under the premise of creative work, belong to the scope of protection of the invention.
Referring to Fig. 1, Fig. 1 is the structure of the agricultural microclimate measure device disclosed in the embodiment of the present invention
Schematic diagram.
Disclosed in this invention agricultural microclimate determine device, including length-adjustable expansion link 3, gas
Dispatch tube 4, gas suction termination 7, gripping handle 2 and gas analysis instrument 1, wherein gas are transmitted
Pipe 4 is arranged on expansion link 3, air delivery tube 4 should reserved margin, in order in expansion link 3
The length of air delivery tube 4 can carry out adaptations, gas suction termination 7 when length changes
Positioned at the front end of expansion link 3, and gas suction termination 7 should be connected with air delivery tube 4, hold
