PLASTICS AS PROTECTION OF CULTURES IN THE MEDITERRANEAN REGIONS

In Europe plastic structures were first tried out for horticulture in the North of Italy.
Originally arched structures of various sizes were used; the results were particularly favourable in strawberries.

Subsequently the high tunnels were joined together into larger units.
For vegetables however, span-roof houses appeared to be more suitable, and again there is a marked trend towards the use of combined structures rather than separate houses.

Polyethylene is now the roofing material° most frequently used.
It is replaced every year.
An increasing number of trials are being made with PVC and photoselective films.
