The present paper presents a review regarding the use of nets and other plastic covers for the orchard protection against hail, rain and late frosts. The installation of the protection systems creates a modified microclimate that influences many orchard parameters and most of these modifications brings benefits for the farmers, as indicated by many studies made in the last decades. Two key factors that seem to be influenced in a positive manner by the plastic covers are the late frosts protection and the earlier maturation of the fruits. In the sweet cherry orchard from the Experimental field of USAMV Bucharest a roof plastic cover has been installed in order to study the evolution of the plants inside and outside the covered area. The new system which has been patented in 2020, assures protection against late frosts, hail and rain, sweet cherries being very susceptible to cracking caused by rain during the ripening season. During the study, will monitor the effectiveness of the protection as well as the impact of the system on the fruit set, the earliness of fruit production, yield quality and quantity, diseases impact and the general evolution of the cherry trees.
