abstract 1341710031 issue 134 pp. 368 – 378 29.12.2017 ru 497
In Nizhny-Volzhsky Agricultural Research Institute at Dubovskoye strong point, by hybridizing local varieties with southern varieties, and by using cultivated hybrids from free pollination, a number of plum varieties combining winter hardiness with high fruit quality have been introduced. The varieties Volgograd, Bogatyrskaya and Vengerka Korneevskaya are sorted, as well as a number of other local Volga varieties obtained by hybridization: Volga Blue, Summer Ternosly, Autumn Ternon with the most adaptive introduced varieties. These Volga varieties are donors of winter hardiness. The environmental conditions of the Lower Volga region contribute to the development of adaptive genotypes that combine winter hardiness with high fetal quality. The use of new varieties of plums obtained in the Lower Volga region, in crosses with the best varieties of plum, allows the creation of industrial varieties of this crop

SUSTAINABILITY OF FOREST PHYTOCENOSISES AND BIODIVERSITY CONSERVATION OF SOUTH-EAST OF WESTERN SIBERIA (TOMSK REGION)

abstract 1341710032 issue 134 pp. 379 – 389 29.12.2017 ru 348
The increasing consumption of forest resources causes a greater anthropogenic impact on forest ecosystems and leads to a negative impact on both biodiversity and the environment as a whole. In this article, the sustainability of forest phytocenosises of southeast of Western Siberia is assessed using the example of Tomsk region. The analysis of the status and dynamics of the forests of Tomsk region has been assessed. The main factors negatively affecting the biodiversity of forests of Tomsk region were analyzed. The forests cover extensive areas; therefore, the studies were carried out based on the data from the State Forestry Register of the Russian Federation for the period from 2008 to 2015. According to the results of the study, the sustainability of forest phytocenosises has increased significantly in recent years, which can be explained by its strengthened ability to maintain the current state under the influence of external factors. This work considers such causes of damage and death of forest plantations as pests, forest diseases, unfavorable soil and climate impacts, forest fires, as these are the main and most massive phenomena that cause the greatest damage to forest. It is possible to see the dynamics of damage and death of forest plantations on the figures presented in the article

Nowadays, domestic pig production is dynamically changing in technological and selection terms and is one of the most effective sectors. In the current conditions of pig breeding in intensive technology, the requirements to the level and direction of pig production, the rational use of genetic resources are increasing. The development of effective methods for the production of pork on the basis of the wide use of highly productive breeds and types of both imported and domestic selection allows to obtain the maximum possible productivity of animals, to produce pork of good quality, to reduce the cost of production and to fully realize the genetic potential of animals. Genetic and selection techniques have significantly changed the physiological, morphological and productive capabilities of modern animals. In connection with this, the actual for the pig industry is the identification of opportunities to increase the duration of the use of pigs, and the inclusion of new indicators in breeding work when creating specialized maternal lines. The research was carried out on the electronic database (KP ACC, OOO "Selikom", Ryazan), the breeding center "Lozovoye" ZAO "Plemzavod-Yubileyniy" of the Tyumen region.

IMPACT OF WAYS OF INCORPORATING RICE STRAW INTO THE SOIL ON RICE YIELD

abstract 1341710051 issue 134 pp. 650 – 660 29.12.2017 ru 237
In the conditions of the two-factor field experiment, the influence of four methods of incorporating straw in the soil on the rice yield was studied: plowing, one-, two- and three-time discs and three ways of "processing" the straw: embedding in the soil of the chopped straw in its pure form, together with compensating nitrogen fertilizer and inoculated stubble biodestructor Stemix ® Niva. It is shown that the lowest yield is formed when straw is plowed, while surface tillage of soil by one-, two- and three-fold discs significantly increases the grain yield in comparison with the plow by 2.4, 4.2 and 5.2 c / ha, respectively. Taking into account that the double disking provided an almost twice increase in the yield of the crop and the absence of statistically significant differences with the triple disking; it is this method of incorporating the straw that should be considered the most expedient. The introduction of a compensating nitrogen fertilizer ensured a reliable increase in yield by 5.1 and 3.7 centners per hectare in comparison with the variants with the introduction of straw in pure form and treatment with biopreparation. Calculation of the share of the influence of the factors studied on the rice yield showed that the method for embedding straw provides 29.9% of the variability of the trait under study, the method of straw treatment is 36.7%, and the residual dispersion accounts for 33.4%. Incorporation of chopped rice straw in the soil together with compensating nitrogen fertilizer in the amount of 1% of the mass of straw, by double discing, ensured the receipt of a conventionally net income of 6940 rubles / ha, the rate of return - 70.4% and the cost recovery - 1.7 rubles / rub

ISSUE OF DEVELOPMENT OF NONWEEDING TECHNOLOGY OF GROWING RICE SEEDS

abstract 1341710058 issue 134 pp. 733 – 742 29.12.2017 ru 252
An analysis of the state of contamination of rice crops with red-grained forms was carried out, as well as impurity was found both in the seed material and in the soil. It was shown that there is a need to switch to non-weeding seed growing technology when conducting elite and reproductive seed production. Various variants of soil cultivation in combating the red rice forms are considered, both in the main and in the pre-sowing treatment. It has been found that after harvesting rice on heavily foul areas, it is better to burn straw, and not to carry out autumn tillage of the soil, the seeds of red-grained forms die mostly when wintering on the soil surface. The most effective method of soil cultivation for controlling of red rice forms in seed crops has been identified, in which the yield is increased, and the contamination of crops and the resulting rice grain is significantly reduced. The work carried out will allow reducing manual labor costs in the production of seeds, improving their quality and assortment, speed up variety changing and variety updating

abstract 1341710060 issue 134 pp. 753 – 759 29.12.2017 ru 235
Urban trees can provide multiple environmental benefits. The study of the state of the street tree and shrubby vegetation from the analysis of inventory data and environmental conditions is purpose the article. The structure of 11 types of street roadside vegetation, which determines about 93% of the greenery composition of the city of Ekaterinburg is considered. The structure of the examined tree-shrub vegetation and all vegetation, which is part of the greening of Ekaterinburg, is compared. For each tree (shrub) was measured: species, number of stems, diameter of stem at 1,3 m, tree height, height to base of live crown, crown width, percent of branch dieback in crown, percent of canopy volume devoid of leaves, number of sides of the tree receiving sunlight from above, distance and direction to building, distance to road. As a result, homogeneity of illumination of various plant species is received. Ash ordinary has the largest of all plants values of the percent of the missing crown (61.3%) and closest distance to the road. The effect on the plants (by average distance) of urban buildings (7- 30 meters) and the proximity of the roadway (3-7 meters) was observed

THE EXPERIENCE OF CREATING A POPULATION OF MEAT-WOOL SHEEP

abstract 1341710071 issue 134 pp. 884 – 894 29.12.2017 ru 304
The study of the productive qualities of crossbred offspring from different breeding combinations and identifying the most effective ones providing the maximum increase in the production of high quality lamb while reducing its cost is an important problem and is essential for further development of methods of creating a new type of precocious meat and wool sheep. In the Rostov region in the result of the establishment of populations of meat-wool sheep there are several groups of animals with different characteristics and hereditary inclinations. As the base of the work there is a method of mating and breeding of sheep of the desired type. The article presents the results of one of the fragments of a large complex work in which the possibility of using three-pedigree hybrids, created with the involvement of potential salskaya, edilbaevskaya and intense meat-wool breed, which is severokavkazskaya, to improve productive quality in the breeding of sheep. We have evaluated productivity and biological features of hybrids and proved the economic efficiency of their use in the production of mutton. We have given the results of the control slaughter and assessment of qualitative indicators of the meat of young sheep. The set of indicators characterizing meat productivity and meat quality revealed that the superiority of the studied indicators remained for two - and three-bred cross cattle. Hybrids have a higher rate of growth and quality parameters of meat productivity. These options are simple and complex industrial crossing are promising and can be implemented and used on the farms of the zone of breeding Merino sheep. Thus, the use of crossbreeding gives an opportunity to convert a flock of sheep in the desired direction quickly. At the same time, three-pedigree hybrids better combine the valuable qualities of the used species

In the soils of rice fields, eluvial gley processes develop, which are manifested in redistribution of silty particles along the profile, water-soluble humus, mobile compounds of iron and phosphorus. Most intensively, these processes are developed in meadowbog soils, confined to closed depressions of the plains plain. Meadow-black soils lying on elevated relief elements have more favorable physical, physicochemical and oxidation-reduction properties for cultivating rice and accompanying crops in crop rotation. The highest yield of rice is formed on high checks and higher at 12,4 c/ha than on low ones
