Innovative technology of reconstruction and remediation of forest shelter belts

Abstract

Field protecting forest belts are nowadays destroyed and require reconstruction and remediation, which means that it is necessary to completely remove the disturbed rows, then prepare the soil and all subsequent silvicultural works, the performance of which with the use of technologies and machinery borrowed from forestry will not yield significant positive results. The technology based on modern achievements in the field of mechanization, including the transformation of the aerial part of the tree-shrub mass into chips and mixing it with the upper soil layer using mobile rotary type mulchers moving at speeds up to 5 km/h; removal of stumps remaining in the soil with a KND-1.1 continuous lifter; collection and removal of uprooted stumps by the picker skidder universal PTU-2.1 is proposed. The KND-1.1 uplifter cuts stumps, shakes them off the soil and leaves them at a speed of 3...5 km/h on the surface with a continuous movement at a speed of 3…5 km/h, 30 times higher than used at KSP-20 uproader. KND-1.1 and PTU-2.1 is a fleet of technical equipment linked to each other in terms of performance. A positive element is that KND-1.1 not only removes stumps, but at the same time prepares the soil for planting in a strip 1,1 m wide and 0,4...0,5 m deep, excluding the use of a plow, a cultivator or a harrow, thereby reducing metal intensity and energy intensity of stumping and soil preparation by 9 and 6 times, respectively.
