Studio dell’estrazione meccanizzata di rizomi di Arundo donax per poter consentire il sezionamento,
la raccolta e l’immediato confezionamento, al fine di ridurre i costi per la produzione di
materiale di propagazione.
|Abstract in English:|
Giant reed is a perennial rhizomatous grass that is currently
indicated as an alternative crop for bioenergy production.
Cultivation of Arundo donax L. for energy purposes requires
the identification of an appropriate propagation technique,
usually carried out with stem cuttings and rhizomes. Both
methods are very efficient, but also very expensive as they
require demanding and labor-intensive manual work. This
study aimed at verifying the viability of a mechanical method
for in situ rhizome extraction, using a modified stump grinder.
Three different machine settings were tested with the goal of
obtaining rhizomes with variable length, ranging between 4.4
and 6.4 cm. The analysis of size distribution of harvested
rhizomes (<5 cm, 5-10 cm, >10 cm) has showed as the
modification of the hoes and the right machine setting would
allow the recovery of almost 90% of rhizomes longer than 5
cm. Rhizomes with different lengths were tested for their rate
of survival and shoots production showing worthy results
on view of applicability of the system for mechanization of
nursery production of giant reed.
