Taking the following relation of plant assimilation into account the contributions of three terms of heat convection, evapotranspiration and assimilation to the energy budget over a paddy and a wheat field have been dealt with respectively:
6MolCO2+6MolH2O+700kcal_??_1MolC6H12O6+6MolO2.
The fluxes of heat, vapor and carbon dioxide are measured aerodynamically under natural conditions and corresponding terms of energy budget are computed and compared with each other. It has been shown that the contribution of assimilation term to the energy budget is sometimes fairly significant, although almost usually it is much smaller than other two terms.
