Rapid measurements of CO2 flux density and water use efficiency of crop community

Abstract

Abstract: In this paper,Eddy Correlation (EC) method was employed to measure the latent heat and CO₂ flux density and to calculate Water Use Efficiency (WUE) of winter wheat community in Yucheng district,Shandong Province in 1997.The results showed that the CO₂ flux density had an obvious diurnal change,with a maximum about1.5 mg·s^-1·m^-2,which appeared at about 9:00～10:00 am in general.The WUE of wheat community presented a fall trend from morning to afternoon,and the CO₂ flux density and WUE also had an obvious seasonal change,being lower in the early and late growth stages,and higher in the middle growth stage.The ranges of daily mean CO₂ flux density and WUE were 0.2～0.9 mg·s^-1·m^-2 and 5～20 gCO₂·kg^-1 H₂O,respectively.

Key words: Photosynthesis of crop community, CO₂ flux density, Water use efficiency, Winter wheat
