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 309
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

THE PATH FOR IMPORT- SUBSTITUTION OF THE USE OF FOREIGN BREED PIGS

abstract 1301706078 issue 130 pp. 1058 – 1065 30.06.2017 ru 312
The extensive path for development in the country in the twentieth century caused low competitiveness of Russian pig production. The productivity of domestic pig production was significantly lower than in Europe, US, Canada and China. Feed costs per 1 kg of gain were 2-3 times higher with a low yield of piglets from a sow per year: 14-16 with an average European 25-27 heads. The country did not have enough meat; as a result, a significant amount of meat products was imported to Russia. Restrictions on imports in connection to the imposition of embargoes contributed to the increase in demand for domestic products and opened new opportunities for Russian producers. One way to increase the production of pork is to use pigs with a high genetic potential for productivity, imported for breeding from Canada and Europe. Based on the conducted studies, it has been established that pigs of foreign breeding have high reproductive qualities, which proves the expediency of their application in commercial pig production to increase the efficiency of the industry development and reduce the import of pedigree youngsters from abroad. The implementation of two breed gilts will help increase productivity in the industrial pig production

MODERN ASSESSMENT OF NUTRITIONAL VALUE OF SORGHUM FORAGE

abstract 1231609052 issue 123 pp. 783 – 792 30.11.2016 ru 314
Sorghum is a source of concentrated, succulent and coarse forage. Its grain is used for making the mixed fodder and as the concentrated forage for swine, cows, sheep, horses and poultry. Sweet sorghum is successfully used for silage and haylage. Green chop of Sudan grass is used as fresh food for domestic animals and it’s used for making hay and silage. The nutritional value of the fodder is the way to meet the animal needs in nutrients, necessary for living. To determine the nutritional value of the fodder, oat fodder units and energy fodder units or exchange energy are used. At present the assessment of nutritional value according to fodder units is being revised, because it doesn’t give the true picture of the value of fodder nutrition and animal needs in nutrients. The general energetic nutritional value of fodder is considered as contents of all organic substances, supplied with fodder or with its energy. The nutritional value of fodder is valued according to the characteristics of its chemical composition, digestion of nutrients and general (energetic) nutritional value. The purpose of the work is to assess the nutritional value of fodder, obtained from the best sorghum varieties, as the food for different kinds of agricultural animals. Sorghum, used as fodder for poultry possesses the largest nutritional value. Among the grain sorghum varieties, the variety ‘Zernogradskoe 88’ has got the biggest value of fodder units. The green chop of Sudan grass and green fodder for silage of sweet sorghum possess the greatest nutritional value for swine. The varieties of Sudan grass ‘Krasava’ and ‘Arkadiya’ and the variety of sweet sorghum ‘Listvenit’ are the best varieties according to the contents of fodder units

The article presents results of the six-year study of the effect of stocks Berlandieri × Riparia Kober 5BB and Chasselas × Berlandieri 41B on yield, quality of grapes and wine Rkatsiteli in the central zone of the Krasnodar region. Effect of stock on the scion strongly depends on the annual weather conditions. In a given year, there is a stock, better adapted to the weather conditions. Stocks of Chasselas × Berlandieri 41B increases winter hardiness variety Rkatsiteli. On average, during six years the stocks have not been resulted in significant difference between the percentages of developed into shoots buds and fertile shoots shown in the coefficients of fruiting and fruitbearing shoots Rkatsiteli. Among all the influencing factors, the degree of influence of stocks is 0.1-0.4%. Some differences in forming of generative organs of wintering buds along the fruiting twig under the influence of stocks do not lead to significant differences in biological terms of fruiting varieties in the whole piece. On average, six years of significant difference in the effect of stocks on the average weight of the bunches, and the yield is not defined - the degree of influence of rootstocks on mentioned indicators is 0,1-2,1%. A significant impact of stocks on the dynamics of sugar accumulation in berries has not been discovered. The degree of influence of stocks on to the final sugar content and acidity of berries is 0.3 and 14.5%, respectively. The wine produced from Rkatsiteli berries on a stock Berlandieri × Riparia Kober 5BB has the better tasting score than on the stock Chasselas × Berlandieri 41B (7.5 and 7.4 points, respectively). The main influence on fruiting of the variety Rkatsiteli was provided by the conditions of the current and previous vegetation. Within the conditions of the central zone of the Krasnodar region the cultivating of the variety Rkatsiteli is reasonable for both studied stocks
