Installation of the protection of the fruit trees and in particular against the vine stocks severe weather

摘要

The protective screens are carried by a series of posts (2), which are spaced regularly along the lines of cultivated bushes. Each post is designed to carry a multi- arm support structure (3), which carries, in turn, the side arms (3a & 3b) and the central vertical arm (3c). The three arms are designed to carry and to allow for the tensioning, of the metallic wires (7), which run along the length of the cultivated row. Covering material (B) is carried by the arms and the wires and is stretched along the length of the cultivated row. The cover is formed with a hem (B1), along both of the longitudinal edges, and which carries the linking cord (C). The ends of the wires and the linking cord are fixed on to the linking posts (10), which are fixed at the ends of the rows. The side tensioners (11) are arranged to attach to points on the support posts and are used to retain the open shape to provide the enclosed area for growing plants.
