The invention relates to forestry, in particular to methods for creating protective stands

The goal is to reduce the consumption of planting material and increase the ameliorative properties of the plantation by simulating the root-sprouting ability of trees when afforested eroded slopes.

The drawing shows a scheme of afforestation of a slope, where 1 is a biogroup, 2 is the direction of distribution of root siblings; 3 - boundaries of the distribution of rye root after felling. 4 - distribution limit of scions from the side of eroded slope 5.

The method is carried out as follows.

At the site intended for planting near the bedrock uterine plantations, soil is prepared. Planting of root-sprout tree species is carried out by the forest planting machine at a distance of 2–3 m from the eroded slope in the spring period. Biogroups are planted in this way equal to the diameter of the distribution of root suckers, depending on the breed (see table).

When the trees reach the uterine plantation during the period of enhanced growth, the best and normal woody plants are cut, for example, with chainsaws. The trees are cut in spring (April, May), when the root systems of woody plants accumulate the largest amount of reserve nutrients. In addition, during this period there is an increase in the intensity of biological processes, good illumination and warming of the soil, which contributes to the mass awakening of adventitious buds of root systems.

Neva system of best and normal trees gives a greater number of viable root siblings. To preserve the viability of tree stumps, cut trees are made at a height of 10-15 cm from the ground. Cut the trees obliquely, which prevents the occurrence of core rot in the stump. The cut is positioned in the north direction to avoid overheating of the stumps and draining of their root systems. A living stump will maintain its root scions until they have an independent root system for 3-5 years.

After removal of the aerial part of the trees of the uterine plantation, their root system produces abundant root shoots, which are distributed, for example, for aspen, within a radius of up to 10 m from the mon tree of each cut tree.

After 8–10 years, the root shoots reach a period of enhanced growth and fix a part of the eroded slope. Subsequently, the trees of the fringing part of the root-shoot resumption are cut from the side of the non-forested eroded slope. This is done similarly to the removal of uterine trees, namely, cutting the best and normal trees that have reached a period of enhanced growth. Work is carried out until the ravine or gully is forested completely.

The use of the proposed method will improve the ameliorative properties of plantations due to the greater saturation of the soil of the eroded area with root
