Shelterbelt plantings in the Voronezh region occupy an area of approximately 60 thousand
hectares. They were created at different times with tree species: poplars, silver birch,
English oak, common and green ash , locust, elm, English field maple and Bosnian maple,
little-leaved linden; bushes – Elaeagnus angustifolia,
yellow acacia, Tatarian honeysuckle, fly honeysuckle, alder buckthorn and other
pure and mixed in composition. Width of the bands, row spacing, and planting density
determine their growth and condition. It was found that in artificial linear stands with the main species of silver birch with an increase of double width, there is average decrease of the growth parameters to 12 %. Mixed cultures of birch are more productive and in them by the age of 25 years conservation, average diameter, height is greater for 4,
8…16, 3 % as compared to pure composition
forest belts. Silver birch is in a dominant
position in the stands with green ash, locust,
Norway maple and forest apple trees.
European ash has higher inventory indices in
co-cultivation with English oak and Norway
maple than with elm and silver birch. Similar
laws are identified also for green ash. For all
the considered species active growth period in
height and diameter up to the age of 10…15
years is observed. At the same time at middleaged
stands on the main soil types, there are
differences in the growth of marginal tree belt
and central belts. During this period of growth
convex transverse profile is usually formed.
Creation of artificial linear plantations in condition of Central Russian Upland is based on the range selection of trees, shrubs, and taking into account soil and climatic conditions, where agronomic and silvicultural methods of creation are funda-mental parameters. Used balsam poplar, silver birch, english oak and other species that accepts placement of seats 2.5-3.0 x 0.7-1.0 m. Forestation of arable land with the help of artificial linear plantations is 1.26 % at area 148.3 thousand. ha.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
