Vliv biotechniky sadby na odrůstání krytokořenného sadebního materiálu smrku ztepilého a buku lesního

Bezdíček, Jiří January 2018 (has links)
The aim of thesis was to determine the effect of the different plantation biotechnique, different types of packaging and soil type for growing up of Norway spruce and European beech ball and balled planting stock. Measurements were performed on two plots within Management-plan area LESCUS Cetkovice Ltd. and it was a combination of medium-heavy-textured and heavy-textured soils. The types of planting for different types of planting stock were determined which were subsequently measured various parameters in the above-ground and underground parts of the plant. Based on the measured values, it was found which of the variants on the given soil grows best and which, on the other hand, is the worst. Furthermore, the strong influence of game on planted plants was detected. For afforestation are suitable ball and balled planting stock with type of packaging HIKO V-120 and HIKO V-350 for Norway spruce and European beech ball and balled planting stock with type of packaging HIKO V 265.

Vliv způsobů sadby krytokořenného sadebního materiálu smrku ztepilého a buku lesního na odrůstání kultur a vývin jejich kořenového systému v 7. lesním vegetačním stupni

Macek, Jiří January 2017 (has links)
The aim of the work was to determine the effect of different seeding biotechniques on overall plant growth and root system development of container seedlings of Norway spruce and European beech in 7. forest vegetation tier. The measurements were performed on two established experimental plots - Forest Management Complex Janovice, district Hubert on forest types 7P and 7K. The tested techniques were as follows: centre hole planting, planting stick, planting tube, planting spade, planting thorn, planting prong and planting cutter. Soil overlapping during planting was also observed. The parameters measured were: losses, height of above - round part, increments, root collar thickness, ratio of roots growing out from root package, vitality and biotic and abiotic damages. The results clearly show that the differing biotechnique of planting has influence on Norway spruce and European beech growth and root system development. Both species on plot 7K grew better and had more expansive root systerm when center planting method was used. On plot 7P the best results for Norway spruce were achieved with planting cutter with overlapping and for European beech with planting spade without overlapping. The center planting method had the lowest losses for both species.

Vliv biotechniky sadby krytokořenného sadebního materiálu smrku ztepilého a buku lesního na odrůstání kultur a vývin jejich kořenového systému v 7. lesním vegetačním stupni

Koudelík, Lukáš January 2018 (has links)
The aim of the diploma thesis was to verify the influence of different seed plant biotechnics on the growth of cultures and development of the root system of the cryopreservation material of spruce and beech forest in the 7th forest vegetation stage. The monitoring was carried out at LS LČR Janovice on forest types 7P and 7K. As the main biotechnology for testing, the seedbed was planted, the seedbed was planted without and with overlay, the seedling was planted without overlapping and seeded with seedless forks without overlapping. The effect of the balloon overlay was also evaluated. To evaluate the influence of different plant biotechnology on the growth of the cultures and the development of the root system we mainly served the criteria of the height of the above-ground part, the thickness of the root neck, the size of the assimilation apparatus, the loss, the vitality, the development of the root system, etc. The best plant biotechnology was evaluated for the spruce spruce on the area 7P planting seedless pipe without overlap and on 7K area planted with seamless sowing. In the case of forest beech, 7P was evaluated as the best seedling without overlap and 7K seedbed without overlapping. The suitability of hole seedlings for both studied species and areas was confirmed. The effect of seedling on the deformation of the root system was confirmed.

Vliv stanoviště a biotechniky sadby na odrůstání kultur založených krytokořenným sadebním materiálem

Novák, Jiří January 2019 (has links)
The aim of this work was to find out how different planting biotechnique of the seed and different site have an impact on growth of container-grown planting material. It was planted norway spruce, european beech and sessile oak on SLT (czech typology system) 5K and 5G. Spruce and beech was planted with five different types of seedlings and oak with three different types. The influence of root ball overlap during planting was also investigated. Measurements took place in 2016, 2017 and 2018. In particular, the following parameters were investigated: the length of the aerial part, the increment, the thickness of the root neck, the length and width of the assimilation organs, the vitality, number of roots rooted in the root ball and the losses. The results show that, the growth of the container-grown planting material is influenced by different biotechnology of seedlings and sites. Planted plants grew better at 5K than at 5G. Best for norway spruce was planting cutter biotechnique for both sites. Best for european beech was center hole planting biotechnique, eventually planting thorn biotechnique. Best for sessisle oak was center hole planting biotechnique. The root pack is better to overlap with a layer of soil during planting.

Vliv biotechniky sadby na odrůstání krytokořenného sadebního materiálu

Nedomanský, Daniel January 2017 (has links)
The aim of this study was to determine the effect of different plantation biotechnics on growth of Scots pine and pedunculate oak containerized planting stock. Both types of planting stock were grown to the same technology type used plantpot QUICK POT D 60 T/12 and 15. Monitoring was carried out by two research areas that have different soil conditions. It was a sandy soil and ground water affected. These areas were located in the Hradec Králové region. We tested following plantation biotechnics: hole planting, planting spade, planting fork, planting thorn and planting stick. It was also monitored overlaps the root ball of a layer of mineral soil. The evaluation was carried out by one growing season after planting. Plant mortality, parameters of above-ground plants part, damage of biotic and abiotic factors, plants vitality and especially root system were monitored. Based on the evaluation of these observations and measurements it has been found which plantation biotechnics are appropriate or not unsuitable for the growing of planting stocks, depending on site soil conditions. The outcome of this work is an overall assessment of individual planting biotechnics and recommendations that the most suitable planting biotechnics for reforestation from above-mentioned planting stock is planting hole.
