Moderní prášková hnojiva s růstovými stimulátory a jejich využití při zalesňování v Krušných horách
Slivková, Tereza
This diploma thesis deals with the use of modern powder fertilizers with growth stimulators, which were used for afforestation of hollow Norway spruce (Picea abies / L./Karst.) after bulldozer soil preparation in the Ore Mountains at LS Klášterec nad Ohří. On these scarified areas of the 7th forest vegetation stage two research areas of Bojiště and Kiosek were established. The battlefield area Bojiště was divided into 6 plots, one of which served only as a check. On these parcels were distinguished Norway spruce (Picea abies / L./Karst.) specimens from growing trees (A) and seedlings (B). Norway spruce seedlings were fertilized with fertilizers series Silvamix® (Sivamix® SR50 + S2, Silvamix® SR30 + S2 and Agluform 90S + S2) and organomineral fertilizers Vermaktiv Stimul and Fungil. Samples of the last year of needles were taken once per year, as well as samples of the soil environment. Support of nutrients were extended and growth spruce cultivation especially by using fertiliziers series Silvamix®. Individual fertilizers were contributed to the promotion of the different nutrients, of course in relation to the composition of fertilizers. Further these fertilizers contributed to improving the vitality of individuals Norway spruce (Picea abies / L./Karst.). The area of the Kiosek was treated with the new fertilizer UNICON. On this area carried two years of research for the sampling of soil samples and the last year needles of Norway spruce (Picea abies / L./Karst.). Against a control variant UNICON has demonstrated the benefits of optimizing the soil enviroment of sprececulture. The overall effect of this fertilizer contributed growth of individuals on the surface and the overall balancing takings nutrients.

Vliv rozdílných způsobů obnovy jedle bělokoré na její odrůstání a vitalitu sedm let po výsadbě
Macek, Jiří
The goal of the work was to find out, what influence different ways of regeneration of silver fir have on its growth speed and overall vitality seven years after plantin. Study was carried out on research area ÚZPL -- LS LČR Svitavy, district of Radiměř. The fir was planted on area partially covered by forest wall, in v gab, with simultaneous planting of fir and larch. There was total of 7 research plots located on acidic stands between 4th and 5th LVS (forest vegetation grade) and variables measured were: losses, height, terminal growth of particular years, width of root collar, total number, length and width of branches, length of needles, colour of needles, shape of crown and trunk, frost and other damage. Results show, that different manners of planting (cover) do have an measurable influence on growth rate and vitality of silver fir. The best results were reached on area partially covered from multiple sides by standing forest and in gab, where frost damage was minimal.

Efekt aplikace minerálních hnojiv a organominerálního stimulačního přípravku na výživu, vývoj a odrůstání smrkových monokultur v PLO 29 - Nízký Jeseník
Hošek, Michal
In selected natural forest areas, was observed the effect of fertilizers on nutrition and re-growth of Norway spruce (Picea Abies). There were established two research areas with secured cultures of Norway spruce. The plots were divided into individual fertilizery parcels. Then on the individual variations were applied fertilizer powder series Silvamix (Silvamix R + stimulator Silvamix A) and organomineral product Vermaktiv stimulus. Influence of fertilizers was evaluated one year after the application. The samples were colected periodically (once year) and the morphological parameters (height,thickness) also. It was observed from the results that the application of fertilizers can affect nutrition and re-growth of Norway spruce cultures. However the effect of fertilizers varies depending on ecological conditions of the station.Top influencing fertilizers were Silvamix R + stimulator and Silvamix A.
