Tree species. Forest crops

Depending on the local climatic conditions, forest crops are planted according to different types.
Mixed plantings, i.e. plantings from different breeds, are more productive than pure (from the same breed), since due to the different needs of individual breeds, the productive forces of the soil and solar energy are used more fully.
For example, an admixture of deciduous conifers that shed foliage for the winter creates conditions in which more precipitation falls on the soil under the forest, especially snow, the soil freezes less, and the loose forest floor absorbs more water that seeps into the depths of the soil. All this significantly enhances the water protection role of forests.

In addition, in mixed forests, the soil is constantly supplied with humus formed from decomposed forest litter, especially from the leaves of shrub species rich in ash substances (elder, yellow acacia, etc.). Mixed crops are more resistant to insect pests and fungal diseases, as well as against drought, frost, winds and fires.
It is recommended to introduce shrubs into water and soil protection forests, since their root system spreads closer to the surface, loosening the top layer of the soil, which improves its structure and moisture capacity. Shrubs also protect the soil from deep freezing, and they hold it together well on steep slopes. Nitrogen-collecting rocks (white acacia, white alder, loch[1], yellow acacia and others) they contribute to the enrichment of the soil with nitrogen.
In a mixed type of forest crops, the main species is distinguished (which is chosen depending on local soil and climatic conditions and the purpose of the plantings being created), related species (which promote the growth and proper development of the main one, preventing tillering, overgrowth, etc.) and species for the formation of undergrowth (mainly shrubby, warming the soil).
When selecting rocks, attention is paid to the interaction of their root systems and aboveground parts.
For example, in the forest belts for the central regions, Mordovia and Bashkiria, the Crimea and the Krasnodar Territory, the following selection of breeds is recommended: the main breed is oak, the accompanying maple is holly, the shrubs in the rows are yellow acacia, and in the borderlands are golden currant.
Moreover, oak and maple alternate in the rows.
For Ukraine, Voronezh, Ryazan, Penza regions and others, Siberian larch is recommended as the main breed, small—leaved linden (a good companion also for oak and pine) is recommended as a companion shrub, common hazel, warty birch, golden currant in the borderlands.
Common pine is also one of the main species in mixed plantings.
