The radiometric properties of the greenhouse covering materials, such as the transmittance in the solar (0-3000 nm) wavelength range, influence strongly the climate inside the greenhouse. Besides the energy balance, the radiometric properties of the materials influence the growth of crops by means of the spectral distribution of the incoming radiation in the different wavelengths. Aim of the work is the definition of a new calculation methodology of the radiometric characteristics applied to the cladding materials for protected cultivation in relation with the crop physiological requirements. Therefore the radiometric properties of cladding materials were measured, and the effect of the transmissivity in different wavelength ranges have been investigated in relation with the agronomic and energetic requirements for a more sustainable greenhouse production.

Abstract
The radiometric properties of the greenhouse covering materials, such as the transmittance in the solar (0-3000 nm) wavelength range, influence strongly the climate inside the greenhouse. Besides the energy balance, the radiometric properties of the materials influence the growth of crops by means of the spectral distribution of the incoming radiation in the different wavelengths. Aim of the work is the definition of a new calculation methodology of the radiometric characteristics applied to the cladding materials for protected cultivation in relation with the crop physiological requirements. Therefore the radiometric properties of cladding materials were measured, and the effect of the transmissivity in different wavelength ranges have been investigated in relation with the agronomic and energetic requirements for a more sustainable greenhouse production.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
