The influence of geo-composite, drip-irrigation and methods of planting on the quality of peach trees obtained in short cycle of nursery material production

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, ...

Effect of soil moisture regulation method in young peach orchard on selected physical properties of soil

The experiment was set founded in 2012 in the Research Station in Samotwór belonging to the University of Life Sciences in Wrocław. The soil moisture in the peach orchard was controlled by the using of drip irrigation and geocomposite placed in the soil. The impact of these factors on the formation of some physical properties of soil was estimated in the 2 nd year of cultivation. It was the 1st year of the peach trees yielding. The soil under irrigation had the higher bulk density in the surface layer and lower values of porosity. The use of polymer gel alone and with irrigation reduced the soil bulk density in the soil layer at 15-20 cm of depth. The soil under polymer and irrigation was characterized by the lowest value of the capillary porosity. Introduction geocomposite into the soil at the time of planting trees can improve the ability of the soil to retain water in the soil and its efficient management throughout the growing season of trees ...
