Možnosti pěstování Paulownia sp. v podmínkách ČR.
Kadlec, Jiří
Cultivation of Paulownia has a very long tradition in its homeland – China, Laos and Vietnam. First, it was planted as a decorative tree in Japan and Korea. Its cultivation spread to all continents, except Antarctica. Paulownia was planted for the first time in the 19th century in the region of today’s Czech Republic (CR). Artificially crossed types of Paulownia (also called art types or hybrids) began to be cultivated around the 1980s with the aim of creating a plant with high-quality wood that is more resistant to disease and a larger-volume production. Due to newly cultivated hybrids, the number of Paulownia plantations has increased. The first plantations where hybrids were planted in the CR were established in the past ten years. However, the results of these plantings are not published and there is no complete methodology for planting, protection and subsequent silvicultural treatment. Therefore, we decided to focus on the possibilities of cultivation of Paulownia in the conditions of the CR, observe and evaluate other growth characteristics and define the necessary protection and silvicultural treatment. The possibilities of cultivation were determined on five research plots, which were established in areas ranging from the warmer lowlands to the colder highlands in Moravia. There, we studied the dendrometric parameters of the plants, the damage caused, and mortality. We also carried out experiments with adjustment of the above-ground part, pruning, protection against frost and irrigation. The results suggest that the climatic conditions in the CR are less favourable than those in the subtropical belt, which is where Paulownia sp. originated and where it is cultivated most. The plant growth is slow at all our plantations, and, in addition, it is affected by frost. Therefore, silvicultural rotation becomes substantially longer, compared to that in the subtropical belt. The greatest problem seems to be insufficient precipitation, a shorter growing season, and more severe and longer-lasting frosts. Less precipitation can be compensated by irrigation, in which case it is necessary to choose the amount of water supplied according to the species/hybrid. Our experiment showed that most of the measured parameters of Paulownia tomentosa and P. Hybrid 9502 were greatest when these plants were supplied 150 l/m2 (and more) per month and those of P. Shan Tong and P. Clon in vitro 112® when they were supplied 100 l/m2 per month. Those of P. Bellissia practically did not change, regardless of the amount of water supplied. Freezing of the root system (and the subsequent death of the plant) can be reduced by covering the soil around the plant. However, freezing of the above-ground part of the plant (according to our results) cannot be adequately eliminated. The best types of protection were the wrapping of the stem with a paper bag, non-woven fabric, or its painting. Nevertheless, approx. 50% of the above-ground part of the plant (with the use of these types of protection) was frozen after winter. It is therefore necessary to extend the annual height increment which, in turn, reduces the number of stem deformations. Also, the height increment can be extended by pruning (i.e. removing the branches and leaves from) the lowest third of the stem at the end of spring. Other factors influencing the growth of Paulownia are the biotechnology of planting, the removal of forest weed, stem protection against sun scorch and protection against animals.

Water management solution of Tršice reservoir
Chyba, Martin ; Fína, David (referee) ; Starý, Miloš (advisor)
The master thesis follows the bachelor's thesis entitled Water management solution of a small water Tršice reservoir. The object of the work is the completion of the water management solution at the Tršice reservoir. In the terms of the storage function of the reservoir, it will be a question of finding a possible increase of runoff for irrigation in the growing season of various crops. In the terms of the protective function, it will be a transformation of flood waves of Tršice reservoirs and below ponds.

Reduction in House Prices due to Humidity
Ocásek, Petr ; Šmahel, Milan (referee) ; Weigel, Lubomír (advisor)
Diploma work "Problems of house price reduction due to defects manifested with damp" deals with the issue of property valuation and subsequent sale of the defect. The first chapter describes valuation and other important factors relating to the Act valuation. The second chapter deals with the necessary documentation for property valuation and basic terminology. The third section deals with defects that could occur in the residential building as well as their possible correction. Another part of this work is focused on the actual valuation of the object to a defect with property damage and the last chapter deals with the actual real estate market and the subsequent sale of such property with the defect. The attachments of the case study is then focused on the valuation of the house and without defects and possible solutions and proposed procedures for sale.

Computer-Controlled Planting
Pospíšil, Jan ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This work is focused on the issue of plant cultivation in domestic conditions. We focused on the automation of the growbox using the Wemos D1 R32 ESP32 board, which then consists of the design and implementation of three parts of the solution, i.e. the growbox itself, including the sensors needed to maintain ideal conditions for the plant being grown, the user applications, for interpreting the values and the configuration of the growbox. Application to collect data from growbox, for later analysis. The solution includes the creation of a demonstration growbox, software for all parts and comparison with available home growing systems.

Precipitation water management in the area of the Brno - Pastviny primary school
Školař, Jan ; Balas, Jan (referee) ; Ručka, Jan (advisor)
The bachelor thesis focuses on the management of rain water in decentralized territory. In the theoretical part, a literature search is made on the possibilities of rain water management and the relevant legislation in The Czech Republic. There are described types of technical solutions for the management of rainwater. In the practical part there is a case study in the area of the Elementary school and Kindergarten Brno - Pastviny for rain water treatment, proposal of underground rainwater tanks with pre-filtration and an automatic irrigation system.

Automated measuring system for irrigating plants with IoT connectivity
Lahoda, Vladimír ; Polák, Ladislav (referee) ; Kufa, Jan (advisor)
This bachelor thesis deals with IoT networks and considers their use as part of embedded devices. The purpose of this device is to control the flower bed or garden based by data from sensors monitoring the environment. The device not only controls the irrigation operation itself, but also sends all traffic data over the IoT LoRa network. Thus, the device also functions as a weather station, as all data are sent to a second device that acts as a receiver. This receiver displays the data and also sends them to the Internet, where the data are publicly available. The module for sending and measuring data is mounted on its own PCB and is covered in a waterproof cover, so they can be operated outdoors. There is an integrated battery, which is a backup of savings in case of power failure. The battery is designed to back up power for 25 days.

Use of buildings rainwater for irrigation and soaking ind the Moravské Křižánky village
Hubený, Michal ; Kameníčková, Ivana (referee) ; Hyánková, Eva (advisor)
The bachelor thesis deals with the issue and utilisation of rainwater. The thesis is divided into two parts - theoretical and practical. Theoretical part consists of general rainwater distribution, the formation of individual rainfall - its composition, quality, surface run-off, individual possibilities of water purification, accumulation and infiltration. The ways of using rainwater in households and gardens are also described in thesis. The practical part deals with the use of rainwater around a family house in the specific location. The area is located in the village called Moravske Krizanky in Vysočina region. In conclusion, a complete solution for rainwater accumulation, irrigation and infiltration was developed.
