Opis (eng)

With the objective to find out the effective and rational methods of protection of coniferous seedlings from the concurrent sprouting vegetation of broadleaves in meliorations, in the period 1986-1988 the possibility of stump treating with chemicals was investigated, in order to prevent their regenerative capability. The treating of stumps of 50 coppice trees, which were cut once a month in the period July-December, was made immediatelly after felling, with the arboricide CIDIKOR (A. S. GLIFOSAT) of 15% concentration in water solution. From a total of 300 treated stumps, at the end of the first vegetation period 195 stumps (65%) were killed, and after the second vegetation period there were 210 dead stumps (75%), i .e. none regenerated shoot had appeared on them. The obtained results have shown that during the investigation period July- December the greatest effect from stump spraying was obtained in October, when only 28% stumps had survived, but the shoots which had appeared on them were less numerous, smaller, of poorer quality and health, when compared with the controls. The obtained results are quite satisfactory, since a reduction of 70% of the competing vegetation gives to the planted coniferous seedlings much more space for their development. When compared with foliar treatment, for which 200-600 liters of water per hectar is necessary, or with mechanical shoot cutting, which must be repeated each second year, this method is more economical and rational and for that reason may be recommended for application in silvicultural practice.
