Zhodnocení škod mrazem na zakládaných lesních kulturách v podmínkách ŠLP ML Křtiny
Patáková, Aneta
On the forest property managed by ŠLP ML Křtiny, an assessment of the damage caused by late frosts on the plantations of forest trees was carried out. Data collection took place at the beginning of the growing season (from May to June), when woody plants begin to sprout and are exposed to the greatest risk of damage from late frosts. Frost events were measured using TMS data loggers, which record the ground air temperature using temperature sensors. The assessment was carried out on young cultures of beech, oak, spruce and fir with a maximum age of 3 years. A total of 28 leguminous areas of different sizes (categories up to 0.1; 0.11 – 0.5 and over 0.51 ha) were evaluated, on which the average damage of the assimilation apparatus was determined on a representative sample of 100 seedlings. The results showed that the most sensitive tree species to late frosts are beech (damaged 56.9 ±30.7% of seedlings) and fir (52.4 ±46.6%).
