Compliance with the sowing technology is the basis for the cultivation of any agricultural crop, since the yield and product quality, material and monetary costs, the seeding rate, the area of plant nutrition, as well as the design features of the machines used, depend on it. When sowing sugar beet, this issue is most relevant because recently, the sowing of this crop has undergone major changes. Most of the seeds used in Russia are both granulated and single-sprout. The seeding rate is set at the final density and, therefore, a delay in the growth of individual plants is not permissible. In this regard, serious requirements are imposed on the design of the seed sowing apparatus, one of the indicators of which is to ensure the placement of seeds on the loose bottom of the sowing furrow, backfilling it with soil from above with subsequent compaction creates unfavorable conditions for seed germination.
The present-day machinery condition and efficiency for mechanical layer detachment of apple clonal rootstocks have been analyzed. The promising scheme of machine suitable for this operation has been found out, and the main parameters have been determined.
Цель: оценить значимость факторов оказывающих влияние на уровень летальности у пострадавших c политравмой в раннем посттравматическом периоде госпитализированных в региональный многопрофильный стационар. Материалы и методы: в работе проведен анализ результатов лечения 3873 пострадавших с политравмой (NISS≥17), пролеченных в ГБУЗ «НИИ-ККБ №1» г. Краснодара за период с 2003 по 2014 гг. За данный временной промежуток проведены переоснащение многопрофильного стационара, реорганизация схемы оказания помощи пострадавшим с политравмой внутри стационара и разработка региональной системы госпитализации. Результаты: в результате проведенной работы летальность среди пострадавших с политравмой снизилась с 39,8% в 2003 году до 8,1% в 2014 году. Заключение: были выявлены и оценены восемь факторов, повлиявших на снижение уровня летальности у пациентов с политравмой. Ключевые слова: политравма, летальность, динамический контроль повреждений, факторы, влияющие на летальность.
Significant losses of beet mass and sucrose occur while storing sugar beets in field piles that lead to an increase in sugar cost supplement. To reduce losses, it is necessary to store raw materials in ventilated piles. Temperature is a key factor in reducing losses. In matters of improving the active ventilation system of sugar beet its work management remains an urgent task. The results of the studies carried out are aimed at studying the temperature regime inside the pile, they made it possible to justify the layout of temperature sensors inside the storage for controlling the active ventilation system.
Russian manufacturing companies do not produce high-clearance equipment for nursery farms growing fruit and berry planting material. In this respect, VIM and Michurinsk State Agrarian University have developed a system of high-clearance machines, taking into account the nursery area, thus providing for effi cient production. (Research purpose) Increasing the effi ciency of growing seedlings and apple rootstocks reproducing in a vegetative way in a mother plantation by means of complex mechanization based on universal technical equipment and technological modules with rational design parameters and kinematic characteristics of working units. (Materials and methods) General methodology for testing machines and working units was supplemented with specifi c methods used in accordance with the research program. The authors made experimental models of machines for spring opening of grafters, cultivating growing shoots, cleaning leaves, and separating branches; provided a system of automatic orientation over a number of plants; and developed a set of technical tools for the care of grafters. (Results and discussion) It has been determined that high-quality spring opening of a mother plantation with the observance of optimal timing for opening shoots increases the productivity of the mother plantation by 7-10 percent. Establishing an optimal environment for plant development using a machine with an active working unit for hilling growing shoots increases the output of standard layering up to 86.2-90.6 percent. Appropriate mechanized separation of layering in improved cutting conditions allowed to increase the yield of standard layering by 5-7 percent, and in the subsequent year there was an 8-10 percent increase in the yield of standard layering (of the fi rst grade) due to their better rooting. (Conclusions) The economic effi ciency of using a universal mechanized set of machinery in a mother plantation is from 514 thousand to 664 thousand rubles per one hectare. The use of high-level technical means of SUVES, VP-1.5 and AP-1.5 with replaceable technological modules increases the level of mechanization by an average of 30 percent, signifi cantly reduces labor costs – up to 20 percent, and improves working conditions for operating staff .
