Analysis of the technical level of grass strip seeding machines in the turf of the MPTD family

Summary. Currently, weak technical equipment remains a deterrent to highly efficient harvesting of high-quality feed, the renewal of agricultural machinery lags behind the rate of its disposal by 3...4 times. The article discusses the results of research on agrotechnical and energy indicators of machines for strip sowing of grasses in the turf of the MPTD family, developed on the basis of the FSАC VIM.

Introduction. The development of feed production is a strategic direction in the development of rational nature management in agriculture in Russia. Natural and seeded forage lands are one of the main sources of feed for livestock. However, significant areas of hayfields and pastures, both in terms of yield and the quality of grasses growing on them, do not meet the requirements of animal husbandry: low productivity of natural forage lands – 7...13 kg/ha of dry matter, unsatisfactory condition of natural lands, extensive system of grassland management, etc. The average annual rate of degradation of grass stands continues to increase due to the lack of advanced technologies and machines for improving forage lands. One of the options for surface improvement of pastures and hayfields is strip processing of sod and planting grasses in the treated strips.

Object. The object of research is the machines developed on the basis of the FSАC VIM for strip sowing of grasses in the turf of the MPTD family.

Materials and methods. The necessary calculations were carried out on the basis of well-known dependencies of efficiency theory and mathematical analysis, optimization methods, and probability theory. Field research was carried out in accordance with current methodological requirements and standards.

Results and conclusions. The analysis of agrotechnical and energy indicators developed on the basis of FSАC VIM machines for strip sowing of grasses in the turf of the MPTD family on the basis of field tests was carried out. As a result, the use of special grassland equipment is justified, which provides an increase in productivity and improvement of the species composition of the herbage of cultivated and natural forage lands with an increase in the yield of grasses by 1.8...2.5 times and a reduction in the consumption of fuel and lubricants by 30...40%.
