Využití technologie úzkých řádků jako protierozního opatření při pěstování kukuřice / Using the Technology of Narrow Rows as an Anti-Erosion Measure in Corn Cultivation

Nevěčný, Karel January 2016 (has links)
Soil is a basic, limited and non-renewable natural resource. It is the natural wealth of each country. Therefore, soil erosion is a major problem not only in the Czech Republic, but also on a global scale. As a result of the erosion process, the stability of soil aggregates is broken; there appears loss of organic matter and nutrient transport, or land within the property or outside. These factors cause irreversible damage to soils, which ultimately has both environmental and economic impacts. As the wide-rows crops areas increase, including corn there increases even the interest of professionals and the public in that problem. At the present, there are searched new technologies of corn cultivation, which should help in elimination of risks associated with that crop cultivation. The aim of this thesis was to analyze selected soil conservation technologies in corn crops in the company ZD Krasna Hora nad Vltavou in terms of their impact on aquatic soil erosion and biomass production. There were analyzed the technologies of tillage disc harrows soil processing, sowing directly into freezing-out crops and as a control a fallow was established. We have also analyzed two inter-rows spacing of vegetation establishment, namely 37,5 cm and 75 cm. The results of this work show an evident positive effect of no-tillage technology of corn cultivation, whether in the narrow or wide rows that are particularly effective at the beginning of the growing season, which is the most problematic for corn. As for the yield of biomass is concerned, the highest yield of biomass was achieved in variants with the width of 75 cm and in technology of sowing into freezing-out crops. The work also includes a literature review, which covers erosion, erosion control measures, corn and tillage systems. Special attention is paid to so-called soil-protection technologies, which are used primarily in wide-rows crops such as corn.

Půdoochranné technologie u třech nejpěstovanějších luskovin v ČR / Three the most cultivated legumes in the Czech Republic with soil conservation technologies

Koukolíček, Jan January 2015 (has links)
The experiment which was done on the fields of Cooperative farm in Nečín should verify three soil conservation technologies with three most cultivated legumes in the Czech Republic. We tested deep cultivation, shallow tillage and no--tillage technology. And we used winter pea which was seeded in two terms in the autumn and in the spring. Spring pea, narrow- leafed lupin, white lupin and soya were seeded only in the spring term. We tested soil density and soil moisture with different soil conservation technologies. We observed vegetation stages and we made pre--harvest and post--harvest evaluation.

Studie čalounění křesel v meziválečné době, doporučení pro rekonstrukce

Kalousová, Adéla January 2016 (has links)
Diploma thesis follows up the classical technologies of upholstered seats from the interwar period. It is particularly focused on the composition of the individual layers of upholstery and feasibility of the construction nowadays. The theoretical part includes description of the interwar period and selected designers and manufacturers of that time. It also describes construction of different types of upholstery and materials used for the construction. The ergonomics of seating and impacts of seating on the human health is mentioned. The practical part comprises of the reconstruction of an upholstered chair from the interwar period. The upholstery was made from contemporary materials, however keeping the classic upholstery technology.
