Abstract
In order to simulate the impact of climate change on cold japonica rice ,through install open top cham‐ber (OTC) in Heilongjiang province to test CO2 concentration ,the stability of gas inside the instrument when OTC running was analyzed .The experimental results showed that variable coefficient of gas concentration in different altitude (50 cm ,100 cm)was lower 0 .04 when OTC running .The change of concentration difference was non‐significant in different time(once per two hours) and different day(continuous ten days) .There was a linear relationship between gas flow and CO2 concentration in gas collecting chamber .The experimental results showed that install OTC in Heilongjiang province could control CO2 concentration in gas collecting chamber and keep the stability of gas concentration .关键词
