Rozšíření databáze mechanizačních prostředků pro zakládání a údržbu travních porostů
Konečný, Tomáš
Main focus of this thesis is to extend the database of mechanical equipment for creation and maintenance of grassland and compile a set of rules for the selection of suitable mechanical equipment with examples. Literary part describes the types of lawns and their demands for maintenance. Machines for mowing, verticutating , land forming and mulching were selected into the database. These machines were supplemented by technical parameters and saved into the database.

Dopad caespestechniky na kvalitu užitkových trávníků
Říha, Tomáš
Utility lawns are lawns that complete the human environment and that is why they need proper care. The objective of this study was to characterized the utility lawns and lawn care. Among the basic caespetechnique measures belong cutting, verticutting, aeration and fertilization. The lawn is necessary to cut as often that maximum 1/3 of the assimilation area would be removed. Verticutting removes lawn thatch of vegetation that prevents the access of water, air and nutrients to the root system. Pruning of the lawn is sufficient twice a year to a depth of 1.5 - 2 mm. Aeration aerates compacted vegetation substrate to a depth of 50 - 150 mm. For sandblasting is used a sharp silicious sand but it is also possible to use new materials such as a crumb rubber. It is necessary to divide the dose of fertilization into several terms to ensure the functionality of the lawn across whole vegetation season. Nitrogen fertilization encourages lawn density by having better offshoots of grasses. The plant tissues are stronger by supplying the required amounts of phosphorus and potassium and it also increases resistance to drought, cold temperatures and fungal diseases.

Vliv trávníkového druhu a ošetření na kvalitu nově založených sportovních trávníků
Daněk, Filip
The subject of this thesis was to assess and evaluate the influence of the relevant turf species and maintenance on the quality of the newly established sports turf. The experiment was founded into the small plots for free repetitions. The factors wich were chosen for evaluation were the degrees of grass species -- perennial ryegrass (Lolium perenne L.), kentucky bluegrass (Poa pratensis L.) and festulolium. The part of evaluation was also the degrees of treated and untreated. For the quality assessmenent of turf species was evaluated the overall condition of the vegetation, state of health of vegetation, regrowth of vegetation and coverage of weeds in vegetation. The analyzes shows that during the growing season under the influences of weather condition, way of maintenance (verticutting, fertilization, mowing) and the occurrence of adverse effects. The vegetation of perennial ryegrass (Lolium perenne L.) reacted best of all species. Lawn turf of this species showed the best performance in terms of quality of the newly established sports turf.

Vliv mechanizačních zásahů a aplikace top dressingu na regeneraci travního drnu
Hotař, Lukáš
Summary The thesis deals with the effect of mechanic invasion and top dressing applications on the quality of the lawn's greensward and weight of the root system of the plant. The aim of this thesis was to evaluate the effect of aeration, verticutation and top dressing in terms of support of plant root system, the presence of weeds in the lawn and also effect on the color of the grass and compactness of the lawn. Made mechanization interventions were evaluated without further intervention, verticutation and aeration. Application of top dressing is evaluated with and without step. The experiment was turfed in the Central region, twenty kilometers southeast of Prague. The greatest effect (P<0,05) on the weight of the root system should aeration with verticutation and smallest (P<0,05) the weight of the root system had lawn without mechanization invasion. In evaluating the compactness of the lawn was rated verticutation (P<0,05) as the worst. The best (P<0,05) color had lawn without any mechanized invasion and least (P<0,05) weed species was found out in combination of aeration and verticutation. Application of organic top dressing showed a positive effect on the weight of the root system. It was also found lower incidence of weeds. For top dressing applications has not been demonstrated a positive effect on the colour of the lawn. Application of top dressing had a positive effect on compactness of the lawn.
