Design improvement of soil-tilling tools for forest side planting

World forestry facing global environmental challenges aims at developing a modern model for utilization and regeneration of forests. Climatic change challenges require ecological potential rise of natural plantings by increasing the forest landscape area. Reforestation is a complex multi-operational process, one of the main stages of which is the broadcast or partial soil cultivation for a new forest plantation. This operation must be strictly a zonal one due to specific natural and industrial conditions. High survival rate of forest plantation and its further development largely depend on the quality of performed work. Modern technical means should be used to ensure high quality of soil cultivation. The authors present bottom and disc plows currently used for soil cultivation in forestry, PKL-70 plow being the most commonly used one. During operation the plow forms a single- or double moldboard furrow. If the seedlings are planted in the furrow bottom of water-logged soil, atmospheric and soil moisture accumulates and as a result plants damp off. Therefore in such conditions forest transplantation should be performed in specially created microhills, in particular in moldboards. Forestry experts note that in this case seedlings take root better and grow more actively. The authors consider modern forest plows designs used for cultivation of waterlogged soils with high plasticity are turfiness. They have developed additional units for refitting forest plows according to the modular-assembly principle. Their usage allows the quality and efficiency of soil preparation improvement by formation of flushed drained microhills for a new forest plantation. The modular-assembly principle may help reduce the range of machines and mechanisms used by forest owners.
