Influence of Scott pine seed size on the quality of seedlings produced

The creation of highly productive forests should be based on the use of high quality seedlings. Those machines and technologies that have been used for cleaning and subsequent sorting of coniferous seeds with their subsequent sowing in the nursery do not fully provide the forestry complex with good-quality planting material. The reason for this is the use of seeds of unsorted fractions in nurseries, the failure to observe conditions during sowing that ensure the amicable emergence of seedlings and conditions in the sowing rows for the normal development of plants, excluding their large mortality and obtaining non-standard seedlings. It should be noted that modern requirements for silvicultural production largely depend on the quality of planting material. Seedlings obtained by growing them without overshooting give a high silvicultural effect if they meet the intended purpose of the cultivated area, have biometric parameters determined by GOST, which make it possible to grow high-quality planting material without overshooting in two growing seasons. The use of innovations in the restoration of forest landscapes is necessary for the cooperation of engineers and researchers. The integration of scientific and technical research and engineering design contributes to the speedy achievement of stringent environmental requirements for vehicle engines and tools. Obtaining high-quality seed is possible while maintaining the sowing qualities of seeds, reducing the degree of injury and treatment cycles, reducing losses during processing and sowing in the nursery. Based on this, there is a need to develop a device for sorting seeds of coniferous species, which will ensure the quality and efficiency of the technological process, as well as obtaining high-quality seed material in a minimum number of processing cycles.
