| Abstract: | The CO_2 content in the air and the wheat canopy and the CO_2 flux density of wheat canopy has been measured with a infrared CO_2 analyser system. Photosynthetic rate and the water use efficiency of the canopy has been calculated in this paper. The relationship of CO_2 flux density between net radiation, wind speed and the exchange coefficient has been analysed and the results are quite satisfy. |
