It is given the integrated assessment under the conditions of Northern Ossetia-Alania of the main agric and biological characteristics and economic efficiency of new apple-tree varieties, immune and steady against a scab, the most from which are created in NCRRIH&V together with State Scientific Institution All-Russian Research Institute of Horticultural Breeding. The research were carried out according to the standard programs and techniques of breeding and variety's studing. The most fast maturing apple-tree varieties of Feya and Talisman which started the fructification for 1-2 year after landing are selected. The high productivity is noted for Carmen, Rassvet, Talisman, Vasilisa and Granatovoe (31,0-38,5 t/hectare). The high yield of standard fruits (to 80-85%) is noted for Feya, Carmen, Orpheus and Granatovoe. The indicators of economic efficiency of cultivation of new varieties are calculated. The most perspective apple varieties for industrial cultivation are selected: Rassvet, Carmen, Granatovoe. High level of economic efficiency of cultivation of these varieties are caused by an optimal combination of immunity to a scab with a complex of the main economic signs: fast and high productivity, fructification regularity, high quality and standardization of fruits. The highest growth of profitability is noted in a group of autumn apple-tree varieties - to 16,6% (Carmen), and in a group of winter varieties - to 24,8% (Granatovoe). In a group of early summer varieties the Rassvet variety on profitability level corresponds to a control variety of Geneva Erli, wich is the one of the best variety of this maturing term. The use for optimization of industrial assortment in the Northern Ossetia-Alania of new apple-tree varieties, immune and steady against a scab, will allow us to increase in economic efficiency of gardening branch and to improve an ecological situation in the region due to decrease in number of processings by means of plantings chemical protection.
The technology of processing of the soil applied now on vineyards on system of black steam is followed by degradation of the soil, the natural process of reproduction of fertility is broken. For decrease in mechanical impact on the soil the biological and resource-saving ways of the maintenance of the soil of vineyards and the effective use of natural resources in productional process of grapes are offered. Merits and demerits of the existing technological processes and cars providing the reproduction of soil fertility are noted. The perspective way of the maintenance of row-spaces of grapes (patent No. 2459399 C1) allowing to eliminate the existing defects is offered: to decrease of mechanical load on the soil, its consolidation, to restore soil fertility. The biological system of the soil maintenance is its basis: the grassy plants sowed in grapes row-spaces remain on a root in adjacent to a soil surface state. So as don't prevent the vegetation of grapes, a grass is bended. The "pillow" formed thus from a continuous grass cover (a vegetative mulch) protects the soil from an overheat, keeps the soil moisture in a hot season, prevents a deep freezing of the soil in the winter, reduces wind and water erosion, deformation of the soil by cars and slows down a mineralization of organic substances. Involvement of organic weight provides the reproduction of water and physical properties and fertility of the soil. At such maintenance of the soil the productivity of grapes plantings increases, power and labor expenses decrease.
The functional essence of ecologization of reproduction processes in viticulture is refined. The areas of negative symptoms in ampelocenosis caused by massive use of chemicals are defined. The efficiency of use of developed biotechnologies in the protection of vineyards is empirically proved and justified by calculation
The necessity of introducing of modern innovations in industrial fruit-growing is justified and the main reasons hindering their widespread use are analyzed. A comparative analysis of agrobiological indicators of apple rootstock types is conducted. Economic feasibility of use of construction without trellis in cultivation of poor growing garden is justified
The characteristic of the processes of intensification in industrial fruit growing is given, their goals are defined. The main technological shifts of the technological structure formed in the domestic fruit growing are presented. Based on the analysis of the development of technological structures, the predicted technological shifts in the near future, the characteristic features of promising technologies in fruit growing, their criteria and signs are presented. Systemically presented factors-signs of intensification of fruit growing. The article reflects the retrospective of the intensification of industrial fruit growing on the basis of breeding and introduction of low-growing rootstocks and differentiated technologies formed with their participation. The main directions of intensification that increase the biopotential of agrocenosis are graphically presented. The analysis of the negative influence of chemical and technogenic factors on agroecocenoses, leading to bioresource deformations in the biocenosis, soil and soil microbiota, microbio -, acaro - and entomosystems, is carried out. The necessity of restoring and developing the reproductive capabilities of agroecosystems, mainly by biological methods, is proved, which include: the development of populations of rhizosphere microorganisms in the soil biota, the expansion of the range of applied biological products created on the basis of effective strains of beneficial microorganisms, the widespread use of various forms and methods to increase plant immunity, including elicitor-type preparations.
