Vliv stanoviště na růst douglasky tisolisté
Karlíček, Josef
The aim of the study was to determine the effectsof the growth the cultures after the first growing season size (coverage). Especially in terms of:a regeneration element, a type of planting stock, fertility habitat and a time of planting. In total, the three plantations were carried out (two spring and one autumn) at six different sites and the only first two were evaluated in this study. 100 seedlings cover-rootedand approximately 100 seedlings bare-rooted were planted at each planting date. In autumn (after the increment of seedlings) there were measured:a length of the herbage, an annual increment and terminal branches, a thickness of aneck root, anumber of live branches on a trunk, branches with needles length, astrain shape, an occurrence of aannual increment branches, a needles color and alength of needles; at a total of about 2,400 individuals. There was also rated adamage of seedlings and an overall health of the planted plants. Subsequently, the statistical analysis was performed according to the particular sites. The results show that the increment of seedlings most affects frost damages, so it is unsuitable for planting large and uncovered clearings. On the contrary, the best results were obtained in underplantings and small clearings. The evaluation also shows that better results are achieved withbare-rootedplanting material. The favorable sitesfor Douglas firfrom the perspective of fertility arethe breeding sites. After comparing early and late spring planting, we can conclude that the time has not significant impact on the growth of the seedlings.

The aim of this thesis was to discover the influence of weed and animals on growth of douglas fir cultures at the management-plan area Jindřichův Hradec. Two research areas with weed (Rubus idaeus (L.) and Calamagrostis epigejos (L.) Roth) were founded in 2011 at SLT 4K and 5S. Growth reactions of douglas fir were monitored on these areas, being it areas with weed left without any intervention during the whole vegetation period or areas with regular full-area weed cutting. The following criteria were evaluated: shoot height, root crown thinkness, growth, height of forked tree sprout, crown height, trunk undulation, branching regularity, number of branches, needle length and trunk shape, soil moisture, chemical composition of the assimilation apparatus and the impact of sunshine. Altogether 512 pieces of douglas fir plants were measured. The results show that douglas fir demonstrated higher height growths every year in areas without cutting than in areas with full-scale cutting, Root crown thickness at SLT 4K was also bigger in the areas with weed. On the contrary, cutting proved to have positive effect at SLT 5S and the root crown thickness was slightly higher here. Two areas, where the influence of animals was simulated, were chosen to find out what the impact of animals on douflas fir cultures growth is. 90 plants were measured in each area and terminal bud damage, terminal shoot damage and side branches damage were compared. A control group of 10 plants, that was left without any intervention, was chosen for comparison. Subsequently their regeneration was evaluated. From the results from measured values follows that douglas plants react to damage by animals with higher height growths which balance the growth length of not-damaged plants. Damage did not even significantly influenced the trunk shape, when all types of damages managed to maintain continuous trunk for minimum of 90 percent of plants in both stands.

The thesis deals with the restoration of the mill and sawmill in Běluň. A more detailed processing is aimed at the sawmill as a better preserved parts of the object. On the basis of the obtained or created documents are drawn up individual alternatives of restoration, which solves the activities carried out during the recovery, the changes compared to current situation, the usability of the object and the resulting economic demands.
