The utility model relates to a kind of indoor
plant carbon
isotope continuous marking device, belong to
isotope tracer device technical field.The device includes marking box,
gas mixing temperature and
humidity device, reaction device, light supplementing device and connecting
pipe.Mark box is made of box and base,
gas mixing temperature and
humidity device includes ordinary fan, air conditioner fan, dehumidification bag and ice box, reaction device includes control type
infusion set,
magnetic stirrer and reaction
bottle, for continuously and stably generating 13 CO2, light supplementing device is divided into two parts
plant light supplementing lamp in marking box, monitoring connecting
pipe penetrates marking box body and is connected with high-precision carbon
isotope analyzer, realizes the real-time monitoring of CO2 concentration and 13 C abundance.The utility model effectively overcomes the
adverse effect of outdoor environment fluctuation on marking process, realizes continuous, stable, controllable carbon isotope marking, significantly improves experimental precision and efficiency, provides strong
technical support for accurately revealing
plant photosynthetic carbon allocation and turnover rule.
