Measuring installation of the real a vegetal cover, for measuring the level of carbon dioxide gas exchange between this vegetal cover and the atmosphere and measurement of the state of hydration of the ground of the covered vegetal

摘要

The present invention relates to a measuring installation of the covering evapotranspiration a vegetal, measurement of the carbon dioxide gas exchange between this vegetal cover and the atmosphere and measurement of the state of hydration of the ground of the covered vegetal comprising a set of sensors 12, 13, 48, 74, 75, 77, 80, an electronic control unit 2 and of calculation and storage unit 3 of the values computed by the unit 2. / p & & p & application: calculating the evapotranspiration by applying the method of the ratio of "bowen" or by application of the method aerodynamic combined simplifiee or by application of the direct aerodynamic simplifiee.
