Description
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

OPTIMIZATION OF WHEAT GRAIN PROCESS GERMINATION CONDITIONS
DescriptionThe article discusses the need to control the technological parameters of wheat germination. A method of intensification of this process is proposed by pretreatment of grain with ultrasonic effect using the ULTA-0.63 / 22-OL apparatus UZTA-0.63 / 22-OL, Biysk. We have evaluated various modes of ultrasonic processing of the grain and their effect on the germination energy and the total number of nested and sprouted grains. We have also conducted optimization of grain processing conditions during germination. Based on the technological capabilities of the device and the optimal modes of ultrasonic exposure, the following exposure parameters were determined: 340 W and 5 minutes of exposure (soft wheat grain) and 397 W and 6 minutes of exposure (grain of durum wheat). The authors note that the intensification of this process significantly depends on varieties and qualities of wheat grain, since the process is complex and depends on many parameters. The use of ultrasonic treatment allows intensifying the soaking process and reducing the duration of this technological operation up to 6 hours for both samples of grain of soft and durum wheat. At the same time, for the necessary moistening of the grain, a ratio of water and grain for 1: 1 is sufficient, since there were no significant differences in the intensity of grain moistening

FEATURES OF THE ECOLOGY OF DRAINED SOILS OF DIFFERENT ECONOMIC USE
DescriptionSlicesize soil is a kind of degradation of its changes. They are characterized by high density, hardness and other characteristics that reduce their effective fertility. Many authors have noted the progression of the process of fusion, which is associated with global warming, with over – compaction due to the unjustifiably frequent use of heavy equipment, irrigation-that is, with the direct impact of abiotic and anthropogenic factors on the pedosphere. Economic use – the strongest anthropogenic factor capable to bring the debugged mechanism of functioning of system out of action if not to observe scientifically-proved rules of agrotechnics. As a result of such intervention, the ecosystem is unable to independently neutralize negative deviations (consequences of anthropogenic impact) from the natural course of the processes of exchange of matter and energy. Therefore, the structure of agrocenoses should be as close as possible to the structure of natural biocenoses, namely: as fertilizers use more organic (manure, green fertilizers); to minimize the mechanical impact on the soil during its processing; to avoid such irrigation regime, which involves excessive soil moisture and its complete drying

Description
In the article, we discuss some of the causes of plant death during the introduction in the south of Primorsky Krai. Introduction studies involving a large number of plant species always have not only positive, but also negative results. According to the results of long-term observations, factors affecting the longevity of plants in the arboretum collection of Gornotayezhnaya station of the FEB RAS are indicated. Regular inventories and annual observations of introduced species in the arboretum of Gornotayezhnaya station of the FEB RAS allowed us to identify the reasons of the decline of introduced species from the arboretum collection: low winter hardiness, fragility, inhibition of plants in thickened planting and due to shading, mismatch of environmental factors, insufficient care, damage to animals. It has been established that for the purpose of the initial selection of new species for introduction research, it is possible to use climatic zoning according to Reder. Analyzing the species belonging to a certain temperature zone and the reason of the decline, it can be conclude that the species belonging to I-III zones in the conditions of the southern Primorye acclimatize quite successfully with good care and a properly selected landing site. Plant species belonging to the IV-V zones need protection from low temperatures at a young age, and some in adulthood. The temperature zones VI and VII are critical for successful acclimatization, so the species belonging to these zones require special attention and careful selection of the place of growth

ASSESSMENT OF WEATHER CHANGES EFFECT ON PEACH CROP IN HUMID SUBTROPICS OF RUSSIA
DescriptionThe close dependence of peach yield on the weather factors in the humid subtropical zone has been established. The observed climate changes in recent years (2000–2018) significantly affected the production potential of peach cultivars. An increase in temperature and precipitation in February-March negatively affected morphogenesis of the flower buds, which reduces the yield of most cultivars. The significant variability of precipitation (the main constraint of peach production) in the winter and early spring, the low weather predictability, characterize the onset of flowering by the “critical” phase. Weather conditions were changed during ripening. In July and August, the amount of precipitation decreased, the temperature increased, which led to moisture deficit and fruits quality deterioration. Local climate change in humid subtropics actualizes the development of adaptive cultivars with a high ecological and adaptive plasticity. Selected clones of the Red Heaven, Krasnaya Zarya and Larisa are the most adapted to the local conditions and can be successfully used in the low mountain area of the subtropics
