Abstract
Production of forest planting material includes many technological processes that subsequently provide the output of the final product. One of the main processes is mechanized sowing. The choice of technology and technical tools for sowing forest seeds is formed on the basis of analytical information about the type of plot, soil structure, methods of preparing and sowing seeds in science and practice of artificial reforestation. The basis for research is the need to find the optimal design of the prototype seeder for the mechanized sowing of dressed seeds that meet the requirements of low energy consumption and increased environmental safety. Systematic and patent search has been used as a research method, providing high-quality and balanced selection of relevant papers. It has been established that the use of one or another technological process of mechanized sowing of dressed seeds in the cost structure for artificial reforestation should be developed depending on the geomorphology of the recovered area, structure, stoniness, soil moisture, soil preparation methods and seed sowing methods. It has been established that the most effective placement during sowing will be a wide-line, strictly parallel at the bottom of the grooves, in which dressed seeds come into tight contact with compacted soil, which is constantly wet due to capillary water, and the returned upper layer plays the role of mulch preventing evaporation moisture. Therefore, optimal conditions are created for seed germination and seedling development. Nevertheless, in the future it is necessary to answer the following questions: how agreed are the opinions of scientists on the feasibility of using ground mechanized seeding? What are a priori the main criteria affecting the effectiveness of the parameters for the precise sowing of dressed seeds?
