Technological process of uniform distribution of fertilizers over the width of the coulter

Abstract

The applied methods of applying fertilizers for cotton in Uzbekistan do not fully ensure the supply of nutrients to the plant's root system. The study aims to substantiate the technological process of uniform distribution of fertilizers in the root development zone and the parameters of coulters. When the fertilizer is distributed in the root development zone in tiers and the right ratio, the coefficient of their use increases, and the yield of cotton increases. The research uses the laws and rules of theoretical mechanics, mathematical statistics, mathematical planning of experiments, and the methods given in existing regulatory documents. The technology of forming new ridges instead of existing ridges and new furrows instead of existing furrows in fields with harvested husk with simultaneous fertilization and an improved chisel cultivator-fertilizer with comb-forming agents for its implementation, as well as the results of theoretical studies to substantiate the main parameters of the tuk coulter chisel-cultivator are presented. The study determined the parameters of universal fertilizer Coulter chisel-cultivator of fertilizer: the base cone of the diffuser in the form of an ellipse with minor axis width 10 mm, height tool provider relative to the upper base of the truncated cone of 60 mm, and a diameter of a half-cylinder of 20 mm.

Physico-mechanical properties of seed pile of fodder crops

“…The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. There are no generalized mathematical models for determining the physico-mechanical properties of the seed pile of fodder crops obtained by the method of sifting plants for seeds [1][2][3][4][5][6]. Determination of the properties of the pile is carried out experimentally.…”

“…During the study period, the moisture content of the pile was determined before each experiment by drying according to a known technique, and the percentage ratio was calculated according to the formula [1,2] % 100…”

“…Seed production is the most important factor in the development of agriculture in Uzbekistan. The production of seeds of high-yielding varieties is very important for obtaining a high yield and improving the quality of agricultural products [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. A seed heap is a material obtained in the process of combing clover plants with a comb of combing drum of the harvesting machine.…”

“…Unlike other harvesting technologies, this method obtains a more concentrated heap of seeds. When harvesting clover for seeds, the inflorescences come off together with fragments of stems, the length of which can range from 5 to 65 cm [1][2][3][4][5][6]. The composition of the heap varies widely depending on the conditions of maturation and contamination of crops, the degree of flatness of plant stems, and other factors.…”

Theoretical prerequisites for improving durability of fixed rolling bearing joints restored with anaerobic

“…Molecular theory [1] studies the molecular interactions between the substrate and the adhesive, provided that they have functional groups capable of interacting. According to this theory, the formation of adhesion bonding takes place in two stages.…”
