OBSERVATIONS FOR THE PRESERVATION AND GROWTH OF FOREST CULTURES OF THE GREEN BELT OF ASTANA

Abstract

In article data of researches of forest cultures of 2012-2014 of landing are provided in state forest resource of Astana ormany LLP. Studying of safety, body height and a condition of plants was carried out. At a pine ordinary the greatest safety - from 87.3% in the cultures of 2012 of landing up to 93.8% in the cultures of 2014 is revealed. Among coniferous breeds - introduced species the greatest safety was at a fir-tree of the Siberian landing of 2014 (81%). Deciduous breeds also had a safety at a high level, except an oak chereshchaty remained only half. Biometric indexes of the assimilatory device of coniferous and deciduous breeds are defined, dynamics of body height of coniferous breeds by years of observations is given. The greatest pluses and height was marked at Pinussylvestris – and 53.2 cm 155.0 respectively. Elaeagnusangustifolia exceeded the height of all the plants - 336 cm. Good height and increase was also noted in hardwood (Prunus, Acer tataricum, Tiliacordata). The plants had a healthy appearance, pests were not observed. On the basis of the obtained data can be recommended for further filling Mikulina spaces: Pinussylvestris as the most adapted for the conditions of Northern Kazakhstan species, Piceaobovata and Piceapungens, although least fastgrowing, but with more decorative qualities of the breed. Hardwood good examples are the small-leaved lime, has a number of useful properties, but keep in mind that under the culture of Linden should choose lesopilenii soil, as well as for Pinussylvestris.
