Efeito do calor armazenado no dossel e no solo no cálculo do balanço de energia em pomar de mangueiras irrigadas.

Abstract

A field experiment was carried out in the production area of ​​Empresa Agropecuária Boa Esperança S.A., located at Km 183 of BR-428“ Petrolina in the State of Pernambuco (latitude: 09°20'S; longitude: 40°27oW; altitude: 365.5 m), in a mango orchard; irrigated by microaspiration. The aim of the research was to investigate whether the heat stored above the plates of heat flux in the heat and in the plant canopy represents a significant contribution in the calculation orchard energy balance. The components of the energy balance were obtained by half of: energy balance method based on the Bowen ratio. The t test was used Student to assess the existence of a Significant difference between the Maya components of the energy balance obtained through:; the following conditions: (i) the heat stored above flowmeters is considered: (ii) the heat stored above the flowmeters is not considered. The results revealed that the heat stored in the mango canopy presents Irrelevant contribution in the energy balance calculation. 0 heat stored above the flowmeters does not significantly interfere at a 5% probability level due to t-Studà-mv test. in the calculation of the evapotranspiration of the irrigated hose, as well as in the components. of the balance of: energy, through 55 conditions for carrying out the experiment of field.
