During the research, we have developed a low-temperature zonal heating panels with an infrared emitter to create a local microclimate for piglets in the suckling period. This heater is lightweight and durable frame in the form of an inverted box size 400 mm x 1800 mm, attached to the wall of the building swivel. Top frame mounted thermostat is connected to a temperature sensor mounted directly on a metal plate with a thickness of 1 mm, painted in black color. In the upper part of the inner carcass layer is a light insulating material, which is located directly under the low-temperature heat source is electric. Study of the optimal size of the heating panel revealed that in view of the limitations associated with the area of the machine and biological characteristics of the optimum size of the sow for 11 piglets are: width – 400 mm; length – 1500 mm (at ventral position) and 1800 mm (lateral position). Comparison of different heating sources for piglets revealed that the use of infrared lamps enables newborn piglets seating area by 55.6%, while in 28 days – by 88.9%. Infrared lamps can not completely meet the recommended specifications as to ensure a more intense heat lamp to be lowered towards the floor surface, which leads to a reduction in the useful area heated. Using as a source of local heating mats and low-temperature panels satisfies pigs in the area of the den in the early suckling period at 138.9 and 200.0%, to weaning, respectively – by 48.5 and 65.5%. Thus, we have developed a low-temperature heating panels contributed to a more uniform distribution of heat in a recreation area of suckling piglets and to provide a comfortable environment at temperatures of 2-3 C lower in comparison with other methods of heating
The key stage of clonal micropropagation, the micropropagation sensu stricto, affords to increase the propagation index for plants, especially perennials. In this study, we consider ways to optimize clonal micropropagation of remontant raspberry cultivars. It is found that microsprout regeneration rate is 78,5–96,0 % on the multiplication s. str. stage. The most multipurpose nutrient medium is selected with containing 0,5 mg/l both of BAP and GK. When one uses this medium, regeneration rate runs 79,0–94,0% depending on genotype with sprout high running 24,8–32,7 mm and sprout number – 1,2–2,2 per node. The optimal duration of growing cycle is 30 days with the propagation index within 6,6–7,8, depending of genotype
The aim of this study is the substantiation of recreational zones in the mountain forests for walking tourists. The article contains a functional zoning, design and spatial solution of landscapes of these zones. The aesthetic and recreational value of forests recreational areas increases the implementation of thinning. Implementation of thinning in the territory of the forest zone allocates places for relaxing and walking. This is the basis of functional separation of recreational areas. Coordinates of the objects of recreational areas (inputs and outputs, the center of the composition, toilets, natural monuments, gazebos, crossing trails and wooden sculptures) are determined using GPS satnav. We can determine the spatial composition of landscapes with forest vegetation, relief and water space. This allows you to allocate places for sight-seeing platforms. Small architectural forms must be in harmony with the surrounding landscape. Walking paths form the basis recreation areas. Turns and bends of routes for walking must comply with the elements of the landscape. Areas for recreation are usually located along the trail in of water bodies and in places of disclosure prospects. The recreation area is limited to with an enclosure which fits into the forest landscapes. In this case, the fence should not interfere with of migration of small animals (herpetofauna, insectivores, and others). The harmony of landscape elements serves as a criterion of completion of design. In the recreation area fire prevention measures have to be carried out by tenants. Permissible load of tourists to recreation areas is determined by a special technique. Conclusions: there was proposed a new kind of recreation facilities in the mountain forests - the zone for walking tourists. When carrying out forestry works, there will be a minimum of expenses on arrangement of the zone. Negative consequences to the forest environment would also be minimized
One of the methods of increasing the productivity of alfalfa is the use of growth regulators, and the use of polymeric compositions of growth regulators, binders with synthesized growth regulators of sim-triazine series is promising with the possibility of creating environmentally friendly technologies for growing alfalfa. Studies have shown that the application of the test on alfalfa growth regulators has a positive effect on growth, physiological and morphogenetic processes, plant resistance to adverse environmental conditions. Intensity impact on plant growth regulators depends on the type of plant growth regulators, concentration and method of application. Processing alfalfa seed growth regulators on germination increases energy 3,0-14,0 % germination on 8,0-17,0 %. Processing plant growth regulators to enhance the growth of plants in height (on the 7th day – 2,6-11,9 % , on the 14th 41,9-48,0 %) , the growth of aboveground biomass , expands on the number of productive branches of the 1st ( 24,1-41,3 %) and 2nd order (21,7-55,0 %). Pre-sowing seed treatment and plant growth regulators alfalfa sim- triazine series contributed to the increase in seed yield of 15,5 %. On average, the yield of green mass increased by 0,8-2,4 t /ha or 5,2-15,5 % and seed yield at 0,19-0,42 h/ha or 8,7-19, 3 %. Growth regulators of sim-triazine series increase the protein content of the vegetative mass of alfalfa at 3,2-4,6 %

Milk productivity of cows is largely dependent on the efficiency of their own genetic potential. For the successful solution of this question it this essential the creation of proper technological conditions for high live stock process of ontogeny beginning from the neonatal period. One of the significant factors that influence the growth, development and safety of young grows in early of young grows in early postembryonic period are zoo-hygienic conditions of calves. Currently the "cold" method of keeping calves in individual houses is developed and widely used. It promotes the increase in the intensity of growth by 8,1%, prevention of diseases of the gastrointestinal tract improving hygienic conditions and rising of profitability of their growing by 4,2%. It is now that calves kept individual houses in the face of increasing wind and decreasing temperatures as well as high humidity of air environment in winter, feel discomfort, move less, stay lying on the litter in the house. For the purpose of warming the animals in cold frosty days keeping outside in the houses, increasing their viability, growth intensity and the guarantee of prevention gastrointestinal tract and pulmonary system diseases development the staff of the Department of private zoo techniques (animal genetics) and pig-keeping from Kuban State Agrarian University have developed Popona - blanket-clothes for calves, which will allow to redirect received from feed energy to a calf growth. It will happen by reducing energy consumption for heating the body and prevent the development of colds due to the formation and preservation of the heat in the body in the absence of wet wool on with the external precipitation
The article contains the results the study of the mechanical composition of clusters and biochemical characteristics of the red wine grape varieties of Cabernet Sauvignon, Cabernet Franc and Merlot (regionalized), Cabernet Carbon, Cabernet Kortis and Verdot black (introduced). In terms of the structure of the cluster of the variety they can be divided into three groups: Cabernet Kortis and Cabernet Sauvignon (16,6-16,8), Cabernet Carbon, Cabernet Franc and Verdot Black (17,5-17,9), Merlot (19.9 ). In terms of addition of the variety they can be divided into four groups: Cabernet Franc (6.3), Cabernet Sauvignon and Merlot (4.9-5.0), Cabernet Carbon (4.3), Verdot Black and Cabernet Kortis (3, 7-3,4). Structural parameters of the clusters of the varieties we have studied were ranged from 5.1 to 5.6, and the berry from 64.3 to 74. The yield of the wort from Cabernet Sauvignon, Cabernet Franc and Merlot is equal to 75,1-77,7% from Cabernet Carbon, Cabernet Kortis and Verdot Black - 70,5-72%. Mass concentration of sugars in the studied varieties was in the range of 22,3-26 g / 100 cm3, titrated acids - 0,47-0,77 g / 100 cm3, active acidity - 3.1-3.8. The ratio of fructose to glucose was: Verdot Black - 1.2, Cabernet Sauvignon and Cabernet Carbon - 1.5, Cabernet Kortis - 1.8, Kabernet Franc - 2.8, Merlot - 3.2. Most ranged organic acid in all varieties – wine acide. Relation of the content of tartaric and wine acids in varieties amounted: Cabernet Kortis 7: 1, Cabernet Karbon 6: 1, Cabernet Franc 2.8: 1, Cabernet Sauvignon and Merlot 2: 1, Verdot Black 1,4-1. Mass concentration of cations in the varieties was (in mg / dm3): potassium - 816,4-1770, sodium - 13,03-21,31, magnesium - 76,21-106, calcium - 52,24-89,45. In comparison with Cabernet Sauvignon larger potassium cations had Cabernet Franc and Merlot, sodium cations - Cabernet Carbon, Cabernet Franc, Merlot, magnesium cations - Cabernet Carbon, Kortis, Cabernet, Merlot, calcium cations - Cabernet Kortis, Merlot and Cabernet Carbon
The article contains information about landscape architecture analysis of the cities, its methodology and an example of using of this approach on the part of the Red Line touristic rote in Yekaterinburg. Analysis process included counting of ratio of built-up areas, landscaping and roads, and examination of the street transvers profile with further filling of local landscape passports. As the object of study, the part of route between the opera and ballet theatre and the monument of V. Vysotsky and M. Vlady. Here is noticeable contrast between environmental characteristics of stopping point areas. The site around the theatre has enough quantity of landscaping, good compositional solution, well developed path network. The intermediate part of the route passing by Krasnoarmeyskaya st. has asymmetric shape of the transvers profile. The street landscaped on East side but public services on the opposite side not improved – homogeneous facade creates adverse visual field here. A sidewalk on the East part of the street duplicated with a path in a garden. Analyzed zone around the second point has no single composition, high traffic influence level. Landscaping almost not presented here, varied advertising constructions widely installed. For improve environment, developed a list of recommendations. It contain using of container plants to separate pedestrian area; reconstruction of the East part of Krasnoarmeyskaya st. with replace sidewalk for green hedge; repair or replacement of sidewalk asphalt pavement on the West side of the street; reconstruction of area near the Antey business-center with creating greened dividing line
There were cited the results of researches for 2010-2012 obtained in the stationary experiment of the chair of general and irrigated land management of Kuban State Agrarian University on the study of influence of the system of main soil processing under soya beans on the dynamics of main agrophysical indexes of leached black soil: on density of composition, solidity, general porosity, coefficient of structural properties in the article. There was stated that in the beginning of vegetation on the background of direct sowing of soya beans, the soil layer in 0-30 cm was characterized by values of density and solidity and in the result of it we observed the weak development of the root system. The worsening of air regime led to the decrease of symbiotic nitrogen fixation, it negatively affected on the growth and development of a cultivar. Agrophysical indexes brought nearer to optimal on variants with disposal tip on 20-22 cm and disk-shaped hulling on 8-10 cm. The worsening of investigated agrophysical soil indexes has been happened since the phase of florescence – soya bean formation till the harvesting. But the variant with disposal tip where we observed the high content of agronomically valuable fraction at the coefficient of structural property 2,42 was the closest to optimal ones. The minimization of soil treatment and especially the denial from its implementation significantly made worse the main agrophysical indexes of soil on variants with direct sowing to critical values for soya beans
This article presents the possibilities of using organic fertilizers, which allow you to recharge grape raw material with biologically active substances and improve the nutritional value of wine production. The influence of organic fertilizers on activation of process for detoxification of soil toxic compounds has been measured, ensuring food safety of raw materials for the production of grape wine products by reducing of hazardous chemicals. The use of biotechnology preserves and also enhances the uniqueness and diversity of the chemical composition of the grape raw material. We have established that after the four-year application of biotechnology the content of toxic compounds in grape raw material was reduced by 7%, and the concentration of biologically active substances increased in 1,5-2% times in comparison with the production of commercial plantations
