【Abstract】 The closed dynamic CO 2 chamber (CDCC 1 chamber)is an automatic system to control CO 2 concentrations. Experimental results indicated that the CO 2 concentrations in three chambers were very stable. In two high CO 2 conentration treatments(750 μl/L and 1 050 μl/L the change of concentrations was less than 1 8%, significantly less than that in the ambient CO 2 treatment (8 17%). Moreover, the temperature and moisture were also precisely controlled in CDCC 1 chambers. So at the same time, four factors, i.e. CO 2 concentration, temperature, moisture and photoperiod were all stablely controlled.更多还原
