Vyhodnocení druhového složení vegetace ve vinicích vybrané vinařské obce

Mertová, Kateřina January 2017 (has links)
The aim of the diploma thesis was to evaluate the species composition of vegetation in a selected wine village. The vegetation evaluation was carried out on three vineyards (Staré vinohrady, Koválov, Horní díly) using a floristic inventory of found species. There were set up vineyard passage routes in the designated area. On the free vineyards were recorded 95 plant varieties together. In addition, an assessment of the species composition of vegetation was carried out on the basis of phytosociological pictures on three different vineyards (V1-production vineyards, V3-old vineyards, V4-newly planted vineyards). In each vineyard were selected 10 habitats. At each habitats were selected 3 phytosociological images. And each images in cultivated belt, stem belt and grass belt. On the three vineyards were discovered 66 different plant species. The evaluation was performed during June and July 2016. The values obtained were statistically evaluated by DCA and CCA analyzes. The vineyard V1 was the most represented Lolium perenne L., Arrhenatherum elatius (L.) J. Preslet C. Presl a Digitaria sanguinalis (L.) Scop. The vineyard V3 was the most represented Calamagrostis epigeos (L.) Roth, Arrhenatherum elatius (L.) J. Preslet C. Presl a Potentilla erecta (L.) Räuschel. The vineyard V4 was the most represented Amaranthus retroflexus L., Chenopodium album L. a Portulaca oleracea L.

Hodnocení nákladů při zakládání vinic

Dvořáček, Marek January 2015 (has links)
The aim of this diploma thesis was to find out the total costs of planting of 1 hectare of wineyard. In the diploma thesis are concentrated figures for assessment of individual cost items in technical methods of wineyard planting. The total costs for wineyard planting were defined on the basis of particular found cost items. In the result part of the diploma thesis there were simulated 2 different options for wineyard planting which were different in number of plant and way of planting. For model A with distance of 2,2 x 0,8 m and number of plants 5200 pieces were assessed total cost for planting of 1 hectare of wineyard in the amount of 613232 CZK -- 5,4% are costs for service of machines, 4,3% are costs for manual work and 90,3% are costs for material. For model B with distance of 3 x 1m and number of plants 3100 pieces were assessed total costs for planting of 1 hectare of wineyard in the amount of 442176 CZK -- 8,5% are costs for service of machines, 5,3% are costs for manual work and 86,2 are costs for material. Knowledge of structure of cost of wineyard planting enables to rationally consider costs of investment and find optimal solution.

Studium technologií zpracování biodegradabilních odpadů z trvalých porostů pro energetické účely

Michálek, Milan January 2014 (has links)
The dissertation thesis entitled "Study of technologies for processing biodegradable waste from permanent crops for energy purposes" is about the use of waste wood material generated after the pruning of crops (vineyards and orchards). The processing of waste biomass from these crops can be used machinery, such as shredders, shredders with reservoir and shredders. In this theses were carried out a series of monitoring of times and computing performance of different machine sets in different conditions. Individual monitoring varied by the use of machinery, cultivation of the variety series length, slope of terrain, spacing, etc. The recalculated performance then ranges from 0,41 to 0,77 hectares per hour. From the time measurements and calculations of costs were for each variant of processing of the vine cane determined values of costs from 880 to 1,357 CZK per ton of wood chips and from 941 to 1,184 CZK per tonne of vine cane compressed into the bales. For the processing of waste wood from orchards, the resulting values were 909--1742 per ton of wood chips and 1128--1505 per tonne of bales. As the most economically advantageous technological progress of processing the vince cane seems to be shredding to the trailer attached behind the shredder. For this method, the resulting cost of wood chips range from 880 CZK per tonne. The same technological process is also proven in the orchards, where the resulting costs per ton of wood chips is 909 CZK. These results confirm that testing technologies provide a competitive bioenergy products. Economic evaluation of monitored technologies depending on the deployment shows that these technologies can be implemented effectively in enterprises with horticultural areas over 45 ha. This area corresponds to medium and large wine-growing and fruit growing enterprise
