The article covers the results of the greenery inventory and landscape-planning structure analysis of Petrovskii park of Petrozavodsk. The features of modern park planning and positional application of trees and shrubs in various types of park and garden stands are described. In the park there were found 47 species of arboreal plants, their distribution by quantity and by different categories of viability was presented. The result of the trees and shrubs condition assessment in this park stated that 63,6% of plants are in good condition, 33,2% of arboreal plants are weakened and seriously weakened, and 3,2% are in unsatisfactory condition and appear to be shrinkable and dead standing. The analysis of the park structure and stand condition allows to offer plant renovation activities
The purpose of this research is to increase the production of concentrated (protein) feed in agricultural enterprises through the use of electronic equipment or robotics and precise precision livestock technology, which will reduce the unit cost of their production. According to the academician L. P. Kormakovsky, accurate, precision technology enables economical use of material resources, which are feeds and their ingredients in the feed, and to obtain optimum results at the highest cost. The most important direction of development of accurate technologies in animal husbandry is the preparation of complete feed mixtures and normalized feeding of groups of animals formed by its productivity. One of the key conditions of efficiency of precise breeding and the use of sophisticated electronic means of control of technological processes is the quality of the feed. Over the past 15 years, concentrated feed forms have been the basis of the diet of most types of farm animals and is the main reserve for increasing their productivity. The article considers models of robotic means of different countries of producers, used in agricultural enterprises for the preparation and distribution of protein feed. The use of robotics currently makes it possible to facilitate human work, and in some cases to replace it. Replacement of a human in all the spheres of activity, for example in preparation of protein forages, at agricultural companies will allow to increase productivity of forage preparation equipment, quality of forages and to provide agriculture of the country with the domestic forages. However, the production of domestic robotics, which are designed for the preparation of protein feed on the basis of oilseeds (sunflower meal, soybean, etc.) is absent, which is a scientific problem. The production of robotics is most developed in European countries. Robotic means which carry out distribution of protein forages, are applied to a lesser extent at the domestic agricultural enterprises, in connection with their features
Reserves of expansion of the areas under fruit plantings in the central part of the North Caucasus are limited, one of solutions of this problem is involvement in an agricultural turn and, in particular, under fruit plantings a little or the slope lands, absolutely inconvenient for one-year cultures, having optimum climatic conditions. Currently, scientifically based technologies of cultivation of gardens on slopes are developed for foothill and mountainous areas of the North Caucasus in relation to zones. Large corporations, as well as medium and small business are engaged in production of fruits in the North Caucasian Federal District. One of problems which vendors of fruits face it is the shortage of the equipment on care of trunk strips and row-spacings of fruit plantings. Mechanized technologies of flat gardening are a little effective in specific conditions of mountain and foothill agriculture where the main limiting factor is the soil fertility. At the same time, the question of the accelerated creation of a humic layer in the trunk strips, improvements of the water and food modes of fruit plantings on slope lands is particularly acute. The carried-out analysis of a system of maintenance of the soil in gardens showed that the most rational is the cespitose and humous system providing bevelling of vegetation with its leaving on the surface of the soil in the form of mulch. However, lots the mower-grinders produced by the industry have rather low rotating speed of a rotational operating part (540 … 840 min-1); they do not provide high-quality crushing of grass vegetation, are incapable to transport crushed grassy masses in trunk strips of fruit-trees. In this regard, we offer a construction of a unit for processing of row-spacings and the trunk strips of fruit plantings. As a result of the conducted theoretical researches, we have set rational values of key parameters of the offered unit
This article is devoted to the definition of criteria for the functioning of agrocenoses. It is determined that the functioning of agrocenoses largely depends on the resource potential: used ecological zones, applied technologies, technological operations and regulations. The basis of effective reproduction and sustainability of agrocenoses is the optimal balance of resources used. The work purpose is the substantiation of optimal parameters of resource intensity of the technological processes in horticulture and the determination of the limits of sustainability of agrocenoses under anthropogenic influences. The integrated assessment of resource intensity of production and technological processes in industrial fruit growing for optimization of its parameters of resource intensity is given. The optimum of reproduction possibilities and limits of stability of agroecosystem components in comparability with the level of technogenic load is achieved by means of regulation of permissible anthropogenic loads in separate elements of agroecosystem and resource balance of elements and processes. The limits of sustainability of fruit agrocenosis under anthropogenic influences are substantiated as well. Regression dependences on technological processes in the context of certain types of resources used are established: capital (depreciation), turnover (material consumption and coefficient of consolidation) and labor (wage). The complex coefficient of efficiency of the economic mechanism of resource saving is defined. The article substantiates optimal parameters of resource-intensive production and technological processes in industrial horticulture. We have also calculated the normative value of the total index of resource intensity of technological processes
The article presents the results of studies on the influence of the conditions of the foothill horticultural zone of the Krasnodar region and the crown shape on the agrobiological characteristics of the growth and fruiting of apple trees of the Idared and Renet Simirenko varieties. The objects of the study are Idared and Rennet Simirenko, trees of winter apple varieties, grafted on MM 106 rootstock. Trees were planted according to the 5 × 3 m scheme; crown width 2.0 ... 2.5 m. Orientation of rows from east to west. The garden is located on the northern slope with a slope of 3 degrees. The scheme of experience: option 1 - sparse-tiered crown (control); option 2 - flattened crown. In the experiment there were 2 options, in each option 10 typical trees were taken. Repetition: tree - plot. The location of the experiment is the Abinsky district of the Krasnodar region. Agricultural records of growth and fruiting of apple trees were carried out according to generally accepted methods, statistical processing of research results was performed by the method of variance analysis described by B. Dospekhov. The results of our studies showed that when flattening crowns, the variety Idared increases the average weight of apples by 22.9%, the yield of fruits of the highest and first grade by 43.6%, the intensity of integumentary coloring of fruits in the peripheral zones increases by 1.44, and in the center crowns 2.7 times, compared with sparse-tier crowns. In the variety Renet Simirenko, the fruit weight increases by 8.9%, the yield of the highest and first grade fruits by 14.6%, the number of fruits with color by 18.7%. Thus, in apple orchards with a 7 x 4 m planting pattern (on MM106 stock) under the conditions of the foothill horticultural zone of the Krasnodar region, flattened tree crowns should be formed for the Aydared variety (aged 14-15 years), which significantly improves the quality of the products
Slope land (ravines, gullies, mountain areas) for many countries of the world are important areas of economic activity, and for some they are the only living space. In the mountainous areas there are cereals and feed, fruit, citrus, nut, berry and essential oil crops, grapes, tea and many others. On slope lands, soil preparation by terracing is widely used. The article considers modern technologies and machines for the construction of terraces in order to create protective and fruit plantations on them and to involve new areas in agricultural turnover. There are two main ways to create terraces: hinged and rifled. Most often, when terracing on tractor-passable slopes, various plows and graders (floor terraces) are used, and on tractor-passable slopes there are universal bulldozers and terrasers (rifled terraces). The shuttle plow PCHS-4-35 and revolving plows are especially convenient for the device of floor terraces, with the help of which it is possible to significantly increase labor productivity by reducing the time for idle runs. For rifled terraces, we use a large complex of machines, the most productive of which are: terraser-Ripper TR-2A; terraced equipment TK-4; terraser T-4M, etc. The use of the proposed complex of machines in the construction of raised and rifled terraces will help to increase productivity and involve new lands in agricultural turnover, which will ultimately increase food security of the Russian Federation
The small-scale intra-economic plants producing loose compound feed are outdated and require reconstruction by method of the modern process lines of compound feed granulation or extrusion adding. But such reconstruction requires a production stop. It is unacceptable for agricultural enterprises. The method of small-scale intra-economic formula-feed plant reconstruction is offered. The method consists in integration into composition of the plant of a modular process line for loose compound feed extrusion or granulation without stopping of production. The building for a new process line is created from the constructive modules representing metal frames with overall dimensions of a standard cargo container in which the equipment, ready to application, is installed. The combined multilevel building of a process line for granulation or extrusion is placed near the main factory building of the existing intra-economic enterprise. Buildings additional and the main production lines form two multilevel production factory building. The example of small-scale formula-feed plant reconstruction by method of integration a modular process line for granulation is explained. The line consists of modules for operational storage and dispensing of loose compound feed, conditioning and granulation, cooling, separation of granules. The traditional formula-feed plant of the fixed structure turns into the transformed system because the configuration of the new modular line can be easily
changed. The offered method of reconstruction is perspective for application on small-scale intra-economic formula-feed plants as allows to reorganize without stopping operating production preparation of compound feed according to the modern requirements, having increased its quality and period of storage. Period of construction of the plant decreases from several months to several weeks thanks to creation of the building of the new line from ready constructive modules
The article provides an overview of domestic and foreign patent information on existing recipes and methods for producing complex feed additives containing probiotic microflora for cattle. Introduction of probiotic cultures of microorganisms to feed additives, along with biologically active substances, allows us to influence the processes of microbiocenosis of the intestines of animals, and, therefore, digestibility and digestibility of feed, which, in turn, leads to an increase in animal productivity. In addition, probiotic cultures contribute to the biodegradation of mycotoxins, which helps prevent mycotoxicity of animals. The most popular in modern livestock breeding are complex feed additives with broad-spectrum probiotic preparations, performing various biological functions
The quality of the seed largely depends on the value of the future crop. For sowing, it is necessary to use seeds with high sowing qualities. This article is devoted to the study of the formation of high-quality seed of new varieties of winter barley, depending on the controlled compaction of crops. The paper describes in detail the importance of sowing qualities of seeds for the formation of high productivity of barley crops. The questions of influence of different seeding rates on laboratory and field germination of seeds are considered. The correlation between the four variants of seeding rates and field and laboratory germination was determined. The purity of seeds of winter barley varieties Kubagro – 1 and Kubagro – 3 was studied and it was determined that the change in the density of the formed stem does not affect the purity of seeds of these varieties. The use of highly productive seeds for sowing and further qualitative cleaning of the obtained grain contributes to the production of seed material with high purity. When considering the weight of 1000 grains in the studied varieties, it was determined that with an increase in the number of productive stems per unit area and a decrease in the area of plant nutrition, both varieties reduced the mass of grains. The highest rates of weight of 1000 grains were determined when sowing with the norm of 3.5 million germinating seeds per 1 ha, such a pattern was observed for both varieties
As a prospect in baking, a number of researchers propose to expand the range of products in the formulation of which include natural food dressers. The article presents the results of research on the development of the optimal formulation of bread from mixtures of wheat flour, wholemeal flour from grains of naked barley varieties Nudum 95 and wholemeal flour from grain triticale varieties Tsekad 90. To select the optimal mixture of wheat, barley and triticale flour, the following variants of the ratios were studied– 70:10:20; 60:20:20; 50:30:20; 50:20:30. As control we took flour of the highest grade from grain of strong wheat Novosibirsk 29. Flour mixtures studied by the gluten content is significantly inferior to the control version of the flour. In the version where 70% of wheat flour was used, gluten decreased by 5.1%, in the version with the amount of wheat flour 60%, gluten decreased by 8.0%. In subsequent variants, the difference in gluten content with the control variant was more than 10%. The lowest rate of flour strength (145 e.a.) in the version where barley flour reached 30% of the mixture. In other embodiments, the flour strength level 209-250 e.a., that is slightly different from the standards on valuable wheat (not less than 260 e.a.). In terms of baking quality has distinguished the case where the proportion of wheat flour was 70%, barley – 10% and triticale – 20% (the volume of bread 500 ml, total score of bread 4 points). In subsequent versions, the performance of baking qualities decreased. As a result of evaluation of mixtures of wheat, barley and triticale flour revealed the most optimal ratio – 70:10:20. This option is recommended for introduction into production for enrichment of wheat flour with nutritious components of barley and triticale grain
