Description

 The invention relates to the forest industry, and in particular to methods of reforestation on dry sandy soils.

 A known method of creating ordinary forest crops, mainly spruce, on clearings with moist soils, including the preparation of the forested area, tillage with the formation of micro-elevations and furrows, planting crops and caring for them [1].

 The disadvantage of this method is that it takes a lot of money to prepare the soil and planting.

 The method of gradual logging, breaking down, cutting into apiary strips and subsequent cross-strip or rocker clear cutting of trees, moreover, the cut down apiary strips of one plot adjoin the cut down strips of apiary of another plot in a checkerboard pattern [2].

 This method assumes the presence of spruce undergrowth before the start of felling, otherwise reforestation will not take place.

 There is also known a method of restoring protective forest plantations, including cutting trees and shrubs, preparing the soil, cultivating the row spacing, deep cultivating the central part of the row without turning the bed, planting forest crops [3].

 The disadvantage of this method is that large amounts of money are spent on soil preparation and planting of forest crops.

 In dry circumpolar pine forests, with the mineralization of the soil, an abundant appearance of undergrowth occurs.

 The technical result is the provision of the emergence of undergrowth due to the mineralization of dry sandy soils.

 This method includes a gradual felling, carried out in three stages. Cutting areas are divided into apiaries using apiary strips in a checkerboard pattern. The width of the apiary strip is 15 m. In the first reception, every third apiary strip is cut down with the simultaneous mineralization of the soil (Fig. 1). By the time of the second intake, after 4-5 years, undergrowth appears in the places of mineralization due to peeling of the grass cover by caterpillars at the cutting site. The second reception of felling is carried out in strips adjacent to the cut down strips in the first reception (Fig. 2). After the third dose (Fig. 3), after 4-5 years, undergrowth appears in the third apiary stripes.

 For felling and stacking of trees used forestry machines on tracked chassis. But for the simultaneous mineralization of the soil, caterpillar chassis with tracks (Fig. 4) having elongated soil loops 1 (Fig. 5, view A. of Fig. 4) are used.

 Implementation of the proposed method allows you to simultaneously renew the forest without cutting costs without creating crops.

Claims (1)

 Reforestation method, including cutting down trees and shrubs, preparing the soil, cultivating the central part of the row, planting forest crops, characterized in that on dry sandy soils simultaneously with harvesting, strip mineralization of the soil is carried out.
