DEPENDENCE OF PEACH LEAF CURL DEVELOPMENT ON WEATHER CONDITIONS IN RUSSIAN HUMID SUBTROPICS (APPLYING ASK-ANALYSIS)

abstract 1311707050 issue 131 pp. 572 – 594 29.09.2017 ru 318
In peach orchards of the Russian humid subtropics, leaf curl is the most dangerous and harmful disease. Due to the high degree of danger from the peach leaf curl, for the first time in this region the main task was to analyze peach leaf curl development on weather conditions. In order to solve the problem, it is proposed to apply a new innovative intellectual technology: automated system-cognitive analysis (ASK-analysis) and its software tools - the “Eidos” system. In order to build the model, based on our own observations and the experience of Russian and foreign colleagues, it was decided to use the following factors: the sum of temperatures above +4 ° C of the current year (for the period from January to April), the sum of temperatures above +4 ° C of the previous year (for the whole year), the sum of precipitation of the current year (for the period from January to April), the sum of precipitation of the previous year (for the whole year), the number of hours of infection (in the current year). It was established that such factors as the number of hours of infection, the sum of temperatures above +4 ° C in April and during the period from January to April, as well as the sum of precipitation in March and April, are the most important in the dynamics of peach leaf curl development and spread. High rates of leaf curl spread and development are caused by the number of hours of infection in the range of 1440 ... 2064 hours, as well as by low air temperatures in March and April (the sum of temperatures above +4 °C – 89,4-240,4° and 283,7-316,7°, respectively) and high air temperatures - in January and February (the sum of temperatures above +4 ° C – 155,3-259,6° and 243,5-280,1°, respectively)

abstract 1291705027 issue 129 pp. 306 – 314 31.05.2017 ru 317
We have presented opportunities to improve the nutritional value of wine production: improvement of biogenetic soil, using organic fertilizers. The nutritional value is ensured by not only high-quality biochemical diversity of berries, but also the safety of products that do not contain toxic inclusions. Bio-fertilizer stimulates the biotransformation of toxic soil residues to replenish soil nutrients for the plant, providing grape raw material with biologically active substances and improves the nutritional value of wine products. Food safety of grapes is ensured by reducing it residues of hazardous chemicals migrating from the soil into the plant and the grapes. It has been established, that after 3 years of application of biofertilizers we significantly improved food safety and quality in the biochemical parameters, especially important for the classic wine grape varieties. The soil content of toxic residues in grape raw material is reduced to 50%, the amount of organic acids increases by: 4,22 mg/dm3(Gallic, coffee acid, chlorogenic; 0.7 g/cm3 amber; of 1.33 mg/dm3 ascorbic; 0.25 mg/dm3 nicotinic

ISSUE OF DEVELOPMENT OF NONWEEDING TECHNOLOGY OF GROWING RICE SEEDS

abstract 1341710058 issue 134 pp. 733 – 742 29.12.2017 ru 316
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

Analysis of rice market in the country was conducted, as well as assortment of rice products was studied. It is shown that rice is the most popular grain in Russian Federation and in percentage of cereal products in shops they occupy 29% and in diet of Russian people – 41%. It is found that in Russia round grain japonica varieties are the most popular kind. It is mentioned that for the last years consumer market demands diversity of rice products, including long-grain and exclusive varieties, imported from abroad. It is shown that in big cities demand for such products has increased from 5% to 15%. Analysis of milled rice balance was conducted. It is found that volume of milled rice in the domestic market of the country is annually about 680-800 thousand tons exceeding the average demand value by 54,8 to 172,3 thousand tons. Promising breeding directions are observed for increasing assortment of rice products in Russian markets with a view to import substitution. It is mentione that Russian breeders have developed group of exclusive varieties: Rubin, Mars, Viola, Violetta, Avstral, Ivushka, Natasha, Aromir etc. It is shown that special purpose varieties currently occupy 3,5% of rice acreage in the Krasnodar region and their cost is by 20-70% higher than that of traditional rice varieties. It was found that for their implementation into production and promotion on the consumer market we need to develop agricultural techniques of cultivation and seed production scheme in accordance with the biological characteristics, conduct marketing activities, promotion of a healthy diet

abstract 1291705085 issue 129 pp. 1172 – 1182 31.05.2017 ru 284
Soil profiles were made in intensive apple orchard in the agricultural enterprises in Lipetsk and Tambov regions in 2015. Drip irrigation in year rates of 500-550 m3 was carried out since 2010. During the research we determined the soil density, the solid phase density, aggregate composition, particle size distribution, the content of hydrolyzable nitrogen and humus by conventional methods. As a result of drip irrigation can increase dust-like fraction in dark gray forest soil, whereas in chernozems this index did not change significantly. In the black earth soil was noted the process of increasing the proportion of mud fraction due to mineral part chernozem destruction. In both soil types was increased sand content. It was found that drip irrigation improves some of the soil water-physical properties, such as a soil structure coefficient and the content of agronomical valuable aggregates in a layer of 20-40 cm. There was also noted that with increasing soil depth was reduced humus and hydrolyzable nitrogen content. In aggregate analysis, it was found that dark-gray forest soil the amount of water-stable aggregates increased, while meadow chernozem leached soil decreased. Data of the aggregate analysis revealed that in the dark-gray forest soil the amount of water-stable aggregates increased as a result of drip irrigation, while in meadow chernozem leached soil decreased. It recommends by drip irrigation application permanent monitoring of the soil humus content

The nutrient structure of fruits of the Mountain ash of ordinary Sorbus aucuparia L., sloe of Prunus spinosa and their extracts is investigated. Inside them, the standard methods in biochemistry have determined the content of extractive substances, sugars, titrable acids, vitamins C and P, phenolic and pectinaceous substances. Results of analyses demonstrate that the fruits of wild plants ripening in the conditions of Dagestan – mountain ashes and sloe - can be effectively used as raw materials for receiving extracts which are rich in vitamins, carbohydrates and phenolic connections. The possibility of production of highquality nutrient-rich extracts from these fruits with application of various technological modes and ways of extraction is revealed: duration of insisting of raw materials; various concentration of ethanol in an extractant and ratios raw materials/ extractant. Results of researches demonstrate that at a ratio of raw materials/extractant 1:3 and the 70% content of ethanol in the extractant have come the greatest extraction from vitamin fruits P (routine) and phenols which made respectively 56,0-65,7% and 51,4-68,3%. Increase in extraction of titrable acids and vitamin C is noted at 50% concentration of ethanol in the extractant. The maximum release of sugars has come from all fruit substrata at 30% ethanol in the extractant. Results of biochemical analyses of extracts have shown that carrying out extraction in the way of double insisting on condition of selection of optimum: concentration of ethanol in the extractant, ratios of the raw materials/ extractant and the best time of insisting, allow to provide on average a 55-60% exit of nutrients from the studied fruit raw materials

THE ROLE OF THE AMBROSIA LEAF BEETLE ZYGOGRMMA SUTURALIS (F.) (COLEOPTERA: CHRYSOMELIDAE), IN THE SUPPRESSION OF RAGWEED AMBROSIA IN THE PRIMORSKY REGION OF RUSSIA

abstract 1311707100 issue 131 pp. 1204 – 1224 29.09.2017 ru 277
Intensification of agriculture during the twentieth century was accompanied by an increase in international trade, resulting in the resettlement of many species across continents. As a result of these processes, many adventives species have become economically significant and dangerous plants in agro and urban biosensors. One such plant is Ambrosia artemisiifolia L., imported from North America to Russia. The use of chemical means of suppression of A. artemisiifolia L. often does not give positive results in agrocenoses, because of its biomorphological features. In urban areas, within the boundaries of sanitary zones, the use of chemicals is prohibited. Therefore, the most promising direction in the suppression of ragweed ambrosia is the ecologies method. The article discusses the possibility of using an ambrosia leaf beetle in the feeding of ragweed in the territory of Russia

abstract 1331709022 issue 133 pp. 263 – 274 30.11.2017 ru 277
Alternation of crops, will remain a fundamental element of zonal technologies of their cultivation for a long time. Application of methods of mathematical model operation will allow to come to new level in the solution of the questions of effective use of an arable land, through application of models optimizing it. Results of researches which basis data of long-term observations are will be especially valuable. They used data of the long-lived stationary experiments on studying of alternation of crops in crop rotations of last more than five rotation. Stationary experiences are located in a forest-steppe zone of Western Siberia on the fields FGBNU "SIBNIISKH". The purpose of researches consisted in optimization of use of an arable land at application of methods of mathematical model operation for preservation of soil fertility. The model allowing when performing particular conditions is given in work (balance of a humus, work expense, a metabolic cost, etc.) to optimize use of an arable land against the background of preservation of soil fertility of the soil, receiving production, economic and power efficiency. It is shown that at alternation of grain crops with clear steam, formation of a harvest happens due to natural fertility of the soil what the negative balance of a humus which reaches 0,18 – 0,78 tons from hectare testifies to. At alternation of field cultures without clear steam the harvest was formed against the background of reproduction of organic matter of the soil, due to increase in vegetable oddments from use of fertilizers, the balance of a humus was positive – 0,15 – 0,28 tons from hectare. Use along with clear steam, busy steam, colza on green fertilizer, and also straw as organic fertilizer for grain crops, 2,01 tons from hectare of commodity grain were received, at a share of clear steam – 16,8%, busy steam – 11%, summer grain – 72,2% of arable land. Increasing in crop rotations of West Siberian Square with use as organic fertilizer of straw, busy vapors and green fertilizers, it is possible to achieve reproduction of fertility of the soil with some decrease in an exit of commodity grain to 2 tons from hectare
