Obnova starih, zapuštenih i opožarenih maslina (II dio)

Vijek ekonomskog korištenja masline je oko 50 godina. Nakon tog razdoblja bilo bi potrebno provesti obnovu stabala. Osim obnove koja se provodi zbog starosti stabala, maslinu je potrebno obnavljati i zbog oštećanja nastalih požarom ili studeni. Postoje tri modela obnove oštećenog stabla: model obnove na panj, model obnove u krošnju i model obnove pojačanom rezidbom. Koji model će se primijeniti ovisi o razlogu zbog kojeg provodimo obnovu i o stupnju oštećenja stabla. Radi neravnoteže između korjenovog sustava i nadzemnog dijela obnovljena stabla imaju intenzivan rast te tako veoma brzo dolaze u produktivnu dob. U starim nasadima masline pri provedbi zahvata obnove potrebno je obaviti nadosadnju drugim sortama i sortama oprašivačima. Za kvalitetnu obnovu potrebno je u obnovljenim nasadima provoditi pojačanu ishranu i redovitu agrotehniku obnovljenih stabala.
Period of economic exploitation of olive-growes is about 50 years. After that period it would be necessary to realise the regeneration of tree. Beside regeneration of old age olive trees it is also necessary to conduct regeneration of trees damaged by fire or cold. There are three models of tree regeneration: regeneration model on trunk, regeneration model of tree top and regeneration model by intensive cutting. The model that should be applied is dependent on reason that caused necessity for regeneration and also dependent on stage of tree damage. Imbalance between root system and above-ground part of plant causes intensive growth of regenerated tree and fast transition to reproductive period. In old olive-growes additional-planting with another cultivars and pollinators is recommended. For quality final regeneration of olive trees intensified application of plant nutrition and regularly agrotechnics is required.
