Increasing the yield of crops is a global challenge substantiated by the scientists from all over the world. To achieve this goal, there are various ways, one of which is the ozonation of seeds before sowing. This method inhibits harmful microflora, which could be formed on the seed during the period of storage, and excites the chemical processes within the seed that can accelerate the process of growth. But despite the positive effect of ozone-air mixture of seeds and a variety of conducting research there is still no reliable data on the technological parameters of ozone effects on seed crops (e.g., corn). In this regard, we have conducted experimental studies to determine the effective parameters of the ozonation of corn seeds, such as the concentration of ozone in the ozone-air mixture, exposure time and binning after treatment. The influence of these parameters was assessed by changes in growth performance of seed, such as germination, germination and growth of strength. Just at the end of the pilot study we carried out a statistical analysis of the data, which allowed us to estimate the degree of influence of each independent parameter (ozone concentration, exposure time, binning after treatment) for each dependent parameter (germination energy, germination, growth force). The data obtained is presented in the article
The aim of the article is theoretical and experi¬mental confirmation of the possibility to improve the acceleration performance of tractor units by in¬stalling a tow hitch with variable stiffness. Application of speed tractors in agricultural pro¬duction meets a number of difficulties associated with the unsteady processes, especially while accel¬erating of machine and tractor units. The resulting large inertial loads during acceleration lead to loss of engine power, due to which the machine and tractor unit operates with less performance and economy. Our analysis of published studies shows that the acceleration performance of tractor units is greatly influenced by the rigidity of external links in the form of coupling devices installed between the trac¬tor and the agricultural machine. The design of the tow hitch with variable nonlinear stiffness for class 1.4 tractors is offered. The results of theoretical and experimental studies on the effect of the proposed tow hitch with variable nonlinear stiffness on the acceleration capabilities of machine and tractor units based on class 1.4 tractor are shown. Based on the analysis of characteristics obtained by the analytical and experimental ways, it was proved that the use of the hitch with a variable non-linear stiffness on class 1.4 tractor helps to improve the acceleration performance of the machine and tractor unit
In the article we show the results of studying the influence of Ecoss enriched biogumat on the photosynthetic complex of radish plants. Seed treatment with humate allows plants to form more powerful root system and develop resistance to various diseases, they are less affected root and basal rot. Plants form a large leaf surface. In leaves we have increased chlorophyll content, they remain longer green, more intense and will accumulate in vegetation greater number of assimilant (carbohydrates), and ultimately increase the yield. More intensive work of the leaves apparatus also contributes to the reduction of nitrates in the production, which is especially important when growing vegetables, melons and potatoes. Humates have a positive impact on yields on soils of different fertility and the different value of the yield. This not only increases the yield of 3 - 5 kg/ha, but also increases the gluten content in grain of winter wheat by 3 - 4%. The application of humates has a high adaptability. Their use can be combined with seed treatment pesticides, spraying crops with pesticides, mineral fertilizers. Therefore, humates are widely spread not only in Russia but all over the world. We have studied the content of chlorophylls and carotenoids at leaf apparatus of radish plants, depending on the methods and doses of the processing with humic preparation
This article describes the results of laboratory experience on the impact of Ecoss enriched Biogumat on the productivity of radish varieties of Corundum in the conditions of artificial climate of Kuban state agrarian University. Sowing was made on November 24, 2014, in two replications. Processing was carried out by humic preparation with a content of humic substances 4 g/L. Humic substances are a special group of organic compounds, the origin of which is associated with the biochemical processes of decomposition and transformation of plant residues (leaves, roots, branches, trunks), animal remains, protein bodies of microorganisms In their composition we have detected humic acids, fulvic acids, salts of these acids, humates and fulvates and Hominy - durable connection of humic and fulvic acids from soil minerals. We have developed different ways of processing plants of radish humic preparation. The influence of this drug on the passage of the phenological stages of plant development was examined for radish and its morphometric characteristics and productivity, depending on processing methods
The article presents a staged scheme for granulation of
solid fraction solids of fermented poultry manure (SF
FPM) in an augered granulator. Granulation process of
material has been reviewed in every stage of
compression. The structural and mechanical properties
of the pressable material were studied. It was revealed
that SF FPM refers to pseudoplastic bodies, which
when exposed to pressure exhibit anomalous
properties. We present a rheological model of the
motion of pressed materials in an augered granulator.
We have modeled a mechanical model of actions at SF
FPM. It was revealed that the compressible material at
voltages generated in an augered granulator at the area
of plasticizing was acting like an abnormal liquid. This
liquid obeys the regularities of Newtonian liquids
