CENTURY-OLD SIBERIAN STONE PINE CROPS GROWTH AND PRODUCTIVITY IN THE ZONE OF CONIFEROUS-BROADLEAVED FORESTS OF THE MIDDLE VOLGA REGION

abstract 1311707097 issue 131 pp. 1168 – 1180 29.09.2017 ru 149
The purpose of the study was to examine a century of experience of growing of forest cultures of the Siberian stone pine in forest conditions in the region of the Middle Volga. To achieve these objectives, we have investigated old growth culture of Siberian stone pine in the conditions of fresh oak forests in the territory of Rootka forestry of the Mari El Republic. Culture of Siberian stone pine was planted after continuous tillage. The distance between rows was 2,5 m, step landing – 1,0 m. The site was divided into five options, depending on variations in the width of planting strip (I-48 m, II-44 m, in III-40 m, IV - 36 m, V - 32 m). The studies have shown that the Siberian stone pine trees, regardless of the variant, are characterized by good clean ability from twigs, which increases with decreasing of the width of the curtain. It can be noted that in the 100-year-old age, the average height of trees reaches of 28,7 m, an average diameter of 49,8 cm. Stock of forest reaches 795,3 m3 /ha. Best annual increase is observed in growing cultures of cedar in the wings with a width of 40 m and is 7,95-of 7,93 m3 /ha. Based оn the research, we have concluded that Siberian stone pine should be recommended for introduction into the zone of coniferous-broadleaved forests of the Middle Volga region. When creating crops, it is necessary to use larger seedlings and plant density is not more than 1,0 thousand pieces/ha, and the width of the planting strip shall be not less than 40,0 m.

RESEARCH OF FLOW OF LIQUID IN THE LABORATORY STANDARD OF BAND OBTURATOR OF WATER REGULATOR WHEN USING SAE-SYSTEMS OF FLOWVISION

abstract 1191605080 issue 119 pp. 1134 – 1158 31.05.2016 ru 150
Limited resource of irrigation water in the South of Russia is a particularly actual task in the production of moisture-loving crops, such as rice. To solve the problem of rational use of water when watering is not possible without the organization of an automated water distribution. As it was shown by the analysis of tools and technologies of regulation of water supply, the most promising, form tested and used, can be tape regulators of flow and water level. They have a simple construction diagram, unpretentious in operation. However, we have identified a fault – unregulated leaking, not fully covered through the bore, which in turn increases the uncontrolled consumption of irrigation water. To solve this problem we propose a number of designs, protected by patents of the Russian Federation, having special fixture to ensure unauthorized leaks, even in a state almost close to the fully closed opening expiration from the regulator. The article comprehensively considers hydraulic studies of controller initially, without any additions that contribute to the problem of eliminating leakage. The proposed study with the analysis of the distribution of velocities and pressures in the design of belt regulator, will allow you to have the basic reference model against which it will be possible to analyze the degree of influence of constructive-technological changes at the work the newly developed devices. For this, we modeled tape controller in the software package FreeCАD version 0.15, when using SAE - system FlowVision. The task of modeling water flow were solved in flat statement, including the moment of full closing of the belt passage opening of the regulator. For plotting surfaces, lines, levels and cross-section response functions, we used a software package wxMaxima. The results obtained allowed a comprehensive analysis of the work tape of the locking device, hydraulically actuated device in all modes of the major factors and, in the future, will help to address the issue of studying the impact of introduced technological changes in the design of controllers

ASSESSMENT OF CARBON-DEPOSIT AND OXYGEN-PRODUCING PART OF ARTIFICIAL FOREST PLANTATIONS OF THE KUBAN FORESTRY IN THE KARACHAYCHERKESSIA REPUBLIC

abstract 1211607103 issue 121 pp. 1677 – 1691 30.09.2016 ru 150
Currently, due to the risk of global warming because of increased concentrations of greenhouse gases in the atmosphere, carbon-deposit function of forest ecosystems, thanks to which stabilization of gas composition of the atmosphere takes place, has great importance [1]. Forest is one of the main components of the biosphere. Forests protect soil from erosion, provide stability hydrological regime of rivers, supply atmosphere with oxygen, biologically active substances, purify of harmful impurities, create optimal environmental conditions and play an important environmental role. However, because of intensive anthropogenic influence (unregulated logging, technogenic environmental pollution recreation) forest ecosystems are experiencing stresses at which irreversible processes of degradation of communities of economically valuable main forestforming species of both natural and artificial origin take place [6]. Evaluating carbon-deposit function of forest plantations, CO2 emissions to the atmosphere through the soil respiration must be taken into account, which can vary within wide limits. Productivity of forests is largely driven by carbon dioxide, released from the soil. Soil carbon dioxide provides demand of forest plants for photosynthesis. With increasing intensity of soil respiration, positive balance is maintained [2]. Based on the method of V.I. Tarankov for evaluation of carbon-deposit and oxygen-producing functions of wood cenoses [2], similar research is carried out in RSI "Kuban forestry", the KarachayCherkessia Republic

DEVELOPMENT OF COMPOSITION OF PARAFFIN - WAX PROTECTIVE COATINGS FOR PRESOWING PROCESSING OF WINTER WHEAT SEEDS

abstract 1261702058 issue 126 pp. 832 – 843 28.02.2017 ru 151
We have proposed the method of presowing processing of seeds of winter wheat using a hydrophobic paraffin-wax system of the new composition. Water protected paraffinceresin coating has been used before for storage of garlic. However, the paraffin coating were not applied to wheat seeds and were not investigated their effect on germination, growth and further development of plants of winter wheat. This work has been done for the first time. The ceresin wax is replaced by sunflower wax. New component composition of the hydrophobic waterproof coating winter wheat seeds: sunflower wax – 15-20 % wt .; paraffin – all the rest of it. Sunflower wax is a surfaceactive substance and has the properties of the plasticizer and the dispersant of the dispersed structure of the paraffin. The advantages of this coating: it protects the seeds from moisture loss, regulates the timing of their germination, contributes to the preservation of accumulated nutrients, and enhances plant growth and development; it increases the yield of wheat. In the field, we have set growth stimulating ability of paraffin-wax coating of winter wheat seeds of variety called Charade. The resulting increase in yield was 20% (control of 52.6 с / ha), while maintaining the quality of grain. This use of sunflower wax solves an important environmental problem – disposal of oilseed production waste

EROSION ZONING OF THE TERRITORY OF THE BRYANSK REGION: THE EXPERIENCE AND CONTEMPORARY PROBLEMS

abstract 1281704092 issue 128 pp. 1309 – 1319 28.04.2017 ru 151
The article analyzes the experience of zoning of territory of the Bryansk region on the main factors of erosion to select the measures to combat it. The Bryansk region in its present borders, mainly representing the middle course of the Desna river, has been considered safe in relation to erosion. The existing zoning is based on the quantitative characteristics of the processes of erosion that primarily allowed us to assess the scale of their impact on nature and the region's economy. The erosion zoning was performed on the basis of the map of erosion-prone land. As a result of study and analysis of all natural factors of erosion and land of the region under study the regularities of distribution of land erosion and intensity of spring rainfall and soil erosion are detected. Under the leadership of Filin V. I., a survey of the ravines of the region was conducted and made the scheme of erosion zoning, according to which the region is divided into three areas. It is noteworthy Horinas E. V. research. When divided into areas it was taken into consideration the need for each of them specific actions to combat the causes and consequences of erosion in relation to the peculiarities of the latter in each district. According to the intensity of the erosion processes and physico-geographical zoning of the Bryansk region and the nature of agricultural land use, specialists of the Bryansk branch of the Institute "Rosgiprozem" produced erosion zoning of the territory of the region, which highlighted seven erosion regions. From the variety of methods for zoning, the most appropriate in our view are created, based on the estimated small-scale (medium-scale) maps of erosion of land, capable of performing the function diagrams of erosion zoning

USING THE BIOLOGICAL RESOURCES OF ANIMALS IN RESOURCE-SAVING TECHNOLOGIES IN CATTLE FARM WORK SITES

abstract 1211607142 issue 121 pp. 2331 – 2368 30.09.2016 ru 152
A fundamental element of the technology is the use of beef cattle in the economic purposes of biological resources of animals. In the development of modern technologies there is a lack of focusing on one of the main features of cattle – its own perception of the environment, that is panoramic (binocular) vision. In the modern cattle breeding we focuse on the development of a variety of exterior signs. However, one of the indicators that affect the behavioral responses of animals (the degree of development of the muzzle and the forehead of the animal, the shape of the head) does not have due importance. The author has conducted its degree of development studies in bulls and cows of different breeds. Along the length of the head, meat breeds (Hereford, Aberdeen Angus, Simmental, Charolais) gave way to Red Steppe 14.9; 15.5; 5.5 and 5.0 cm (27,5; 28,6; 10,1 and 9,2%, P

abstract 1311707057 issue 131 pp. 672 – 683 29.09.2017 ru 152
In the conditions of middle valley of the Lena River on the cryogenic, inundated, cespitose and chernozemic soils different steppe communities differently react on dietary regime. Herb-grass phytocenosis at organic dietary regime is reformed in cereal phytocenosis with the contents of cereals to 76% and bean types 19% of dry basis with productivity to 20 centner of hectare of dry basis. At the same time the efficiency of the improved phytocenosis was on charge exchange energy of 17,3 mega joule of hectare, feed units 1032 and a crude protein of 247 kilo of hectare. The whetgrasses phytocenosis has provided productivity to 19,4 centner of hectare and the content of perevarimy protein in 1 feed unit up to 118 gram. So the most effective for the steppe meadows is using complex fertilizer (humus of 20 tons of hectare + N60P60K60), increasing the productivity twice with a high quality of food
