THEORETICAL JUSTIFICATION OF CONSTRUCTIVE AND REGIME PARAMETERS OF THE ARABLE AND MILLING UNIT
05.20.00 Processes and machines of agroengineering systems
DescriptionPre-planting preparation of soil in the Central part of the North Caucasus according to the traditional technology of cultivation of crops involves the use of single-operation soil processing machines and aggregates. As a result, they have to make multiple passes, resulting in increased energy consumption, soil compaction, and the emergence and development of erosion processes. In addition, the agricultural machinery used is characterized by the low operability and reliability of the working elements and their joint assemblies, which leads to a decrease in productivity, so that the agricultural requirements for the process of pre-sowing soil preparation are often not met. In order to solve the above-mentioned problems, an arable milling unit for pre-sowing soil preparation is proposed. Its structural and technological scheme is justified. The distinctive features of the proposed design are the possibility of the main soil treatment with simultaneous grinding of large soil clumps, lumps, plant residues and levelling of the soil surface; possibility of changing the installation angle of the rotary grinder and depth of soil treatment depending on the type of treated soil; high quality of soil preparation for sowing; provision of energy consumption reduction due to combination of technological operations in preparation of soils for sowing; lack of expensive assemblies and parts; the need for less energy for aggregation when preparing soils for sowing. As a result of the theoretical studies carried out, rational values of the main parameters of the proposed arable milling unit have been established, which have a decisive influence on the process of its operation: speed of movement 1.5... 2.0 m/s; Angle of attack of working element 20... 300; Angular rotation speed of the working tool 20... 25 s-1

05.20.00 Processes and machines of agroengineering systems
DescriptionReserves of expansion of the areas under fruit plantings in the central part of the North Caucasus are limited, one of solutions of this problem is involvement in an agricultural turn and, in particular, under fruit plantings a little or the slope lands, absolutely inconvenient for one-year cultures, having optimum climatic conditions. Currently, scientifically based technologies of cultivation of gardens on slopes are developed for foothill and mountainous areas of the North Caucasus in relation to zones. Large corporations, as well as medium and small business are engaged in production of fruits in the North Caucasian Federal District. One of problems which vendors of fruits face it is the shortage of the equipment on care of trunk strips and row-spacings of fruit plantings. Mechanized technologies of flat gardening are a little effective in specific conditions of mountain and foothill agriculture where the main limiting factor is the soil fertility. At the same time, the question of the accelerated creation of a humic layer in the trunk strips, improvements of the water and food modes of fruit plantings on slope lands is particularly acute. The carried-out analysis of a system of maintenance of the soil in gardens showed that the most rational is the cespitose and humous system providing bevelling of vegetation with its leaving on the surface of the soil in the form of mulch. However, lots the mower-grinders produced by the industry have rather low rotating speed of a rotational operating part (540 … 840 min-1); they do not provide high-quality crushing of grass vegetation, are incapable to transport crushed grassy masses in trunk strips of fruit-trees. In this regard, we offer a construction of a unit for processing of row-spacings and the trunk strips of fruit plantings. As a result of the conducted theoretical researches, we have set rational values of key parameters of the offered unit

06.00.00 Agricultural sciences
DescriptionThe article is devoted to the estimation of the dependence of perennial grass herbage’s productivity on the dose and distribution of nitrogen fertilizers during the vegetation, as well as from the dynamics of the species composition by years of use. It was revealed that for cocksfoot-timothy grass mixture an increase in the rate of nitrogen fertilizer for every 10 kg of active ingredient leads to an increase of yield by 0.27 tons/ha. The selection of components of grass mixtures and rational fertilizer doses forms the herbage which provides a yield of about 7,0-12,0 tons/ha of dry mass and 58,1-99,6 GJ of energy exchange. It is established that competitive relations in grass mixtures are exacerbated with increasing doses of fertilizers. The timothy grass develops successfully in a mixture with the cocksfoot with a low level of mineral nutrition (N80). A high level of mineral nutrition speeds up the formation of single-species herbage - the cocksfoot. Meadow fescue grass provides sustainable yields on medium and high backgrounds of mineral fertilizers in combination with the cocksfoot. Recommendations for a nitrogen dose of more than 200 kg per hectare for fertilizing mixed grass crops with the cocksfoot and about 100 kg per hectare for clover-cereals mixtures without cocksfoot are suggested
