Abstract

In order to limit the internal air temperature during summer and create optimum cultivation conditions in the greenhouses, a common solution utilized by growers is the shading against excessive solar radiation using plastic nets; this is due to their photo-selective properties. With the aim to analyse the efficacy of the shading effect of plastic nets in different climates, experimental trials have been carried out on some identical small-scale tunnels installed in two different locations, one in Mediterranean area (Acerenza—Southern Italy) and one in arid conditions (Riyadh—Saudi Arabia). These tunnels have been covered with a plastic film and shaded with a white plastic net installed either in contact or at a distance of 20 cm over the cladding film. The radiometrical characteristics of the plastic film and nets have been determined through laboratory tests, while the internal microclimatic conditions have been monitored inside these experimental tunnels in both locations. The obtained results are the base for a comparative analysis to evaluate the performance of different nets, and to explore the role of shading on the temperature reduction and quality of light in different climates.
