Abstract: Crops were exposed to both 350 and 700μl/L of CO2 in the plant growth chamber designed with high，middle and low soil moisture treatments，with the soil water contents of 85%-100%，65%-85% and 45%-65%(percentage of field capacity) respectively. This paper analysed the combined effects of the atmosp

Key words: Soil moisture regime, Atmospheric CO2 concentration, Evapotranspiration, Photo-synthesis, Water use efficiency
