The experiment was carried out in 2006-2008 years in the nurseries, in the Experimental Station belonging to Wrocław University of Environmental and Life Sciences. The aim of present study was to determine the influence of drip ir-rigation and agrogel on the growth of Pumiselect® rootstock in the first year of production and on the quality of maiden trees of ‘Redhaven' and ‘Inka' cvs. peach trees. The drip irrigation was used as a T-tape line with drip emitter lo-cated at every 25 cm in line, about water dose 1,38 l per hour. Irrigation was applied on the base of tensiometer indications. The wet agrogel placed inside a belt of fabric (wide 10 cm), was put on the bottom of furrow (at depth 35 cm) , where the plants were planted. Pumiselect® rootstock as the hard-cuttings were planted at spacing 2 x 0,25 m at the depth 35 cm. The budding was done at the beginning of August by ''chip-budding'' method at 5 cm above the soil. During the experiment: the high, diameter and branching of rootstock and maiden trees was measured. The quality of root system of rootstock was determined too. The preliminary results shown the positive influence of ...
The quality of one -year -old peach trees of 'Saturn' cv. on Manchurian seedling rootstocks was estimated in this experiment. The rootstocks with ‘sleeping bud' were planted in spring 2012 directly into the orchard in two different ways: traditionally -in the holes and in ridges, with a spacing of 4 x 1.5 m. The factors of the study were: the method of planting and different levels of soil humidity, obtained by the use of: drip irrigation, geocomposite and combinations: geocomposite with 50% the dose of irrigation. Geo-composite had the capacity of 1.6 L and consisted of: superabsorbent, inner plastic net, and outer nonwoven fabric.Preliminary studies have shown the usefulness of technology based on shorter production of nursery cycle, by planting rootstock with buds to the orchard. A requirement for using of this method is to provide the best conditions for the growth of maiden trees. Favorable conditions for the development of maiden peach trees in the orchard ensured planting in ridges. The high quality of one-year-old peach trees were obtained with traditional planting and under control conditions. Regardless of the method of planting, strong growth and high quality parameters of maiden trees has also provided by drip irrigation, ...
The aim of the present research has been an attempt at evaluating the water requirements of peach trees over 2016-2050 in the Bydgoszcz region drawing on the forecast changes in temperature. The paper draws on the forecasting of mean monthly temperature for the Bydgoszcz region in 2011-2050 according to the climate change scenario for Poland SRES: A1B (Bąk, Łabędzki 2014). The water requirements of the peach tree have been determined based on the indispensable precipitation determined by Kemmer and Schulz. The water requirements were calculated for the period January through December and May through September for each year in the 35-year period (2016-2050). The reference period was made up by a 35-year period immediately preceding it (1981-2015). In 2016-2050 in the Bydgoszcz region, in the light of the forecast scenarios of changes in temperature, one should expect an increase in water requirements of the peach tree. Determined according to the Kemmer and Schulz method, the required optimal annual (January-December) precipitation will increase for peach from 486 mm to 612 mm (by 126 mm, which accounts for 26%). The optimal precipitation time variation trend equations show that in the reference period (1981-2015), calculated based on the Kemmer and Schulz number, the ...
