Abstract

The invention relates to forestry, in particular to the cultivation, maintenance and restoration of protective forest plantations. The purpose of the invention is to reduce costs and preserve the fertile soil layer in the silvicultural area. A method of restoring protective forest plantations includes cutting down trees and shrubs, preparing the soil, planting new forest crops and caring for the soil on silvicultural and buffer tapes. After cutting down all the trees and shrubs, leaving reduced stumps with a height of no more than 5 cm, the entire width between the beds is cultivated to a depth of 10 to 15 cm, and its central part is 20 to 25 cm wide, treated to a depth of 40 to 50 cm without turning the seam and planted into it new forest cultures. Soil care on buffer tapes is done by mowing the weeds as they grow or a single treatment with herbicides in early spring, on forest crops tapes by cultivation by the method of sedaning a number of crops, and as they grow to a height of 1 m and more, by saddling buffer tapes with mon mi In the case of cutting down of hardwood plantations, to prevent over-production capacity, the stumps are treated with arboricides. Crop survival is 93%.

Description

The invention relates to forestry, in particular to the cultivation, maintenance and restoration of protective forest plantations.

The purpose of the invention is to reduce costs and preserve the fertile soil layer in the silvicultural area.

The technological process of restoring dead defensive plantings includes cutting trees and shrubs, leaving lowered stumps no more than 5 cm high, preparing the soil for planting on silvicultural tapes - the former inter-year spans - by a depth method, in which the soil is treated to a depth of 10 - 15 across the entire silvicultural ribbon. cm, and the central part between the widths of 20–25 cm is loosened by a deep-ripper to a depth of 40–50 cm without turning a layer and forest cultures are planted in it.

Example. The proposed method has been tested in the dry steppe zone when restoring dead forest shelter belts. Trees and shrubs are cut down by any bunkers or gasoline-powered saws, leaving reduced stumps no more than 5 cm high. The stumps and roots lowered against the usual cutting of the roots are left without grunting until complete decomposition. In case of need, in order to suppress the ability to coppice, individual stumps are simultaneously treated with arboricides simultaneously with felling. After harvesting the cut wood on silvicultural tapes (the former

3 m wide and more) the soil is cultivated by cultivators to a depth of TO - 15 cm.

The middle of silvicultural tapes with a width of 20-25 cm is treated by passing deep-looseners of the PH-60 or PH-80.5 type to a depth of 40-50 cm.

When cultivating to a depth of 10–15 cm, the cultivated area is satisfactorily cleared of weeds, and contact of the working bodies with large skeletal roots, which are placed at a depth of more than 20 cm in the silvicultural tape, is excluded. which provides normal conditions for the operation of forest planting machines. To prevent the weeds from growing over the weeds of buffer tapes having a width of 0.7–1.0 m, where the stumps of the former stand are located, a one-time early spring treatment with herbicides or periodic weed mowing is carried out. After planting, the soil care after planting is performed by KRL-1 or PR VN-2.5A cultivators using the sedan row method, and as the plants grow to a height of 1 m or more, buffer ribbons with rows of reduced stumps grow.

The remaining stumps and roots enrich the organic part of the soil after their natural decomposition. A fertile soil layer in the amount of 300–500 m / ha is preserved on the silvicultural area.

Crop survival is 93%. Labor and energy costs are reduced.
