Hodnocení způsobů výsadby a povýsadbové péče na růst sazenic révy vinné

Holánek, Jiří January 2019 (has links)
The aim of this thesis was to conduct operational monitoring of selected machines in the process of planting a new vineyard. The thesis focused on choosing a suitable site and a subsequent pre-planting preparation. Individual methods of site preparation, technological methods of planting a vineyard and different types of supporting systems were all described in the theoretical part. The objective of the practical part was to monitor the machinery operating and fuel costs. Measurements of time consumption of individual working operations and cost calculation were also conducted, and a required number of workers was recommended. Last but not least, models of different technological methods for planting a vineyard were developed and cost differences of individual methods were observed. Finally, measurements and evaluation of seedling establishment and growth during the growing season of 2018 were conducted and statistical outputs were derived from the data. The thesis yielded a large amount of data suitable for further practical application.

Hodnocení defoliace vinic s ohledem na stanovení rozsahu redukce listové plochy

Tisarová, Mária January 2014 (has links)
This thesis deals with the evaluation of defoliation of vineyards with respect to determination of extent of leaf area reduction in the varieties Hibernal, Zweigeltrebe and Cabernet Moravia. The experiment was conducted in 2013 at the experimental sites in the cadastral area of Lednice in Moravia and Rakvice. The development of leaf area was evaluated by ADC device BioScientific Ltd. during three periods (June, July, August) in the phenological stages of flowering phenological stages of fruit development and ripening of the fruit phenological stages. From the measured data was determined leaf area index (LAI) and the extent of defoliation. Using analytical methods parameters of quality grapes were evaluated - the sugar content, pH, acidity, assimilable nitrogen, and others in order to determine the optimal time of reduction in leaf area of a vine. Part of this work was also the evaluation of operating costs for Defoliator.

Noční motýli jako indikátory kvality zemědělské krajiny a úrovně biodiverzity při různém režimu hospodaření

Šafář, Jaroslav January 2012 (has links)
This work deals with a research of moth species diversity in selected vineyards of southern Moravia that are often located in the vicinity of specially protected areas and often directly linked to them. When using sound agricultural practices, vineyards can provide a kind of stepping stones for a large number of endangered and rare species in their path to find suitable habitats to survive, or the environment of vineyards may be partially or even permanently colonized. During 2010 and 2011 in six vineyards and two forest-steppe areas, 8,061 specimens belonging to 309 species (12 families) of moths were collected using portable light traps. Based on some ecological indices, DCA, RDA, CCA analysis, Spearman's correlation coefficient, etc., the relationship between moths and the influence of farming in the vineyards (conventional, integrated, organic) in terms of agro-technical practices and the influence of natural and semi-natural habitats in intermediate vineyards surrounding on the moth communities of the monitored localities was evaluated. The results show that species diversity increases with vineyards having cover crop in the absence of application of chemical insecticides and especially with maintaining selffloristic succession in vineyard alleyways with cover crop. In RDA and CCA analysis, certain species responded significantly to the influence of studied factors of vineyard farm management, and for some species there was a significant effect of habitats in the immediate vicinity of monitored areas, but this effect did not reach statistical significance such as vineyard management factors examined.

Stanovení obsahu rtuti v materiálech v jednotlivých fázích výroby vína, geochemie rtuti ve vinici / Determination of mercury content in materials in various stages of wine production, geochemistry of mercury in the vineyard

Buchtová, Jana January 2011 (has links)
This work was focused on determination of mobility of mercury and its content in materials from each part of the wine production process. The aim of this work was to establish the most suitable analytical method for determination and evaluation of changes in content of mercury during the production process. Samples of soil, biomass, vine wood, vine leaves, berries, grapes, rough wine and cider sediment of red wine and also four liquid samples of white wine were analyzed. All the samples originated from the area of Malé Žernoseky and Rudoltice nad Bílinou, white wine samples were collected in Chrámce u Mostu in the northern part of the Czech Republic. Analyzer AMA 254 was used for determination of mercury in solid samples and liquid samples had to be prearranged by PSA analyzer. This analytical approach was not so sufficient and mercury from liquid samples had to be captured by gold-coated amalgamator in first step and then analyzed by AMA 254. Obtained results confirmed interception of mercury mostly in leaves and in the grapes peelings. The grapes from Rudoltice contained 0,0022 mg/kg in dry mass and further processed wine grapes contained 0,0068 mg/kg in dry mass. The lowest content of mercury was in cider and completed wine contained less mercury then the rough wine. Unfiltrated cider from Chrámce has...

Rozdíly v druhové diverzitě a abundanci pavouků na hlavách révy vinné na terasovaných a klasických vinicích v závislosti na typu hospodaření

Havlová, Lucie January 2018 (has links)
Spiders belong to one of the most important natural pest antagonists in many agroecosystems. The species diversity and abundance of spiders, hence their biocontrol potential, is directly related and is often increased by the presence of non-agricultural, non-productive areas in the landscape directly surrounded with agroecosystems. My research was focused on spiders related to the vine plats trunks, first of all as organisms reflecting the function of vineyard terraces in relation to increasing their heterogeneity, which in turn reflects on the resulting biodiversity of the landscape, and secondly as pest antagonists in vineyards, which can effectively and nature-friendly contribute to the sustainability of agricultural units. Research areas in the South Moravian Region were selected and species diversity and spider abundance were analyzed. Two vineyards at each site have been selected: classic - plain vineyards and terraced vineyards which were lined with non-productive slopes. From November 2013 to October 2014, 727 adult spiders belonging to 21 species and 7 families were recorded. Concerning the vulnerability of each species, 12 abundant species were found, 4 species were almost threatened, 3 were endangered species, 1 species was strongly endangered, and 1 species was critically endangered. According to the results, we can state that the species spectrum of spiders found on vine plant trunks may in the future function as a biocontrolling agent and may have an interesting influence on vine pests.

Hodnocení vlivu pojezdů mechanizačních prostředků na utužení půdy v meziřadí vinic =:Evaluation of the impact of mechanical means on soil compaction in vineyards. /

Klasa, Ferianc Juraj January 2019 (has links)
The dissertation thesis deals with the evaluation of the influence of the movements of the mechanization devices on soil compaction in grassed and cultivated vineyard between the lines after application of graded doses of organic matter (compost). This question was verified using penetrometer measurements. For the purpose of experimentation were selected in the vineyard region of South Moravia three experimental habitats with different soil conditions (Lednice, Velké Bílovice, Mikulov). In the autumn of 2013, the application of compost to the cultivated intercooler took place in doses of 5 and 10 kg.m-2. Penetrations measurements for each experimental site were carried out in four variants (grassed between the lines, cultivated between the lines, cultivated between the lines with application of 5 kg.m-2 and cultivated between the lines with application of 10 kg.m-2). Individual measurements were performed using a Eijelkamp penetrometer, which works at an accuracy of 99.9 % and its working depth is 800 mm. At the same time, soil samples were removed to determine the current soil moisture. Based on the measurements, high values of soil compaction were found for all monitored habitats. At the same time, the positive effect of the organic mass produced in the form of compost on the total soil compaction was demonstrated, which was 20 % lower in autumn 2016 than in the autumn of 2013. The worst was the period of spring 2014 and autumn 2015. The highest values of penetrometric resistance of the soil were measured from the rule for grassed between the lines. On the contrary, the lowest values were measured for the variant of the cultivated between the lines with the application of 10 kg.m-2. The parts of the dissertation are also the results of the evaluation of pressure transmissions using the TASC program and the results of the tire imprint.
