Abstract in Italian:
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.
