Abstract

The intensive development of forest areas in the Russian Federation leads to the need for a significant amount of work related to reforestation. High-quality soil preparation is the key to successful survival of forest planting material of economically valuable species. Traditional technologies of forest soil preparation by dump plowing are outdated today and do not allow to radically increase the level of labor productivity. In the work, calculations were made of the power costs required for soil preparation in the process of mineralization by a forest plow of the PLP-70 type. It has been established that a standard tractor of the Onezhets-300 series, when moving with a plow in a cutting area with simultaneous cutting of shrubs and small forests, allows for confident processing at a speed of no more than 0.3 m/s. This ensures productivity up to 1.5 hectares per shift. To ensure the growth of shift output up to 3.5...4 ha per shift, the required tractor power is at least 250 kW. Domestic serial forestry tractors cannot provide productivity growth, since they have an internal combustion engine power less than required.
