Justification of machine parameters for ridge forming with simultaneous application of fertilizers

Abstract

The technologies used to prepare the soil for sowing cotton seeds in Uzbekistan have a number of significant drawbacks. Therefore, reducing labour and energy costs, as well as saving resources when cultivating crops based on advanced technologies and developing high-performance agricultural machines is of current interest. The aim of this study is to substantiate the machine parameters for forming ridges in the cotton fields with a simultaneous application of fertilizers. New technology has been developed for the formation of ridges with a simultaneous application of fertilizer in the fields with harvested cotton stalks, which loosens the soil in the middle of existing furrows of the cotton-plant, loosening the existing ridge with simultaneous application of fertilizers and forming new ridges in their place in one pass. An improved chisel – cultivator – fertilizer with ridge – forming agents were developed to implement the proposed technology. It has been established that the formation of a high – quality ridge is ensured with local fertilizer application along with a sowing line of a required degree with the following relative positions of the machine’s working bodies: a minimum longitudinal distance from the cultivator to the support wheel is 20 cm, a minimum longitudinal distance of the ridge former to the cultivator coulter is 31.3 cm, the distance between adjacent rippers 60 or 90 cm, the transverse distance from the cultivator to the support wheel is 30 or 45 cm.

Traction resistance of the combined machine plough

“…Soil deepeners designed for subsurface loosening of the soil are widely used on plows [1][2][3][4][5][6][7][8][9][10][11], combined tillage machines . As a result of the subsurface loosening of the soil, the most favorable conditions are created to grow and develop plant roots.…”

Anti-erosion technologies and technical means for tillage in the conditions of Uzbekistan

“…In the system of agrotechnical methods, the main moisture-saving role is assigned to methods of soil cultivation, which should ensure the most complete accumulation of moisture from atmospheric precipitation in the root layer and prevent its evaporation through the treated soil layer. Therefore,to prevent water runoff and soil washout it is necessary to apply special anti-erosion soil cultivation technologies [6][7][8][9][14][15][16].…”

Ripper for processing slope fields

“…It is relevant to conduct targeted scientific research on the development of dump and non-dump anti-erosion working bodies, ensuring resource conservation in the processes of their interaction with the soil. Research on the development and application of machinery to protect the soil from water and wind erosion, in particular machinery working bodies of the "paraplu", studying their performance and justification of the parameters studied F.Mamatov , B.Mirzayev [4][5][6][7][8][9][10][11][12][14][15][16][17][18][19][20][21][22][23] V.Alexandrian [28], A.Vagin [29], N.N.Nagorny [30], V.Svetlichniy [30], V.M.Drinca [32], D.A.Tryapitsyn [34], Pazova T [33], B.Borisenko [32] and others. The machines and tools created as a result of these studies are used with certain positive results in the tillage of the slopes.…”
