### CREATION OF A TREE OF PHASES OF THE FOURFOLD MUTUAL SYSTEMS Na,Ba∥F,Cl,WO4

#### Abstract

Multicomponent system is the basis for the development of compositions with

desired properties. Previously, the study of topology of multicomponent systems

was carried out using graph theory (method of indices of vertices). Due to the

complex topological structure of component relationships, the study of such systems

is currently underway with the use of innovative methods: computer simulation

and experimental study using the capabilities of modern hardware and

software of the experiment. In the framework of the innovative methodology of

the study the reciprocal Quaternary system Na,Ba||F,Cl,WO4, at the level splitting

in stable Association phases. The tree phases was confirmed experimentally

by means of DTA and XRD.

### INFLUENCE OF PRESEEDING PROCESSING OF SEEDS OF FLAX ON GROWTH AND BIOCHEMICAL INDICATORS OF SPROUTS

#### Abstract

Due to the continuous reduction of the areas for crops and increase of urban

population, the increase in productivity of crops is especially important

aspect in production of food today. One of problems of agriculture is creation

of conditions for receiving a crop. Quality of a crop of various crops depends on

efficiency of preseeding processing of seeds. This research investigated a method

of impact of preseeding processing of seeds of flax by a complex of physical

factors: ultra-violet radiation, ozone and the magnetic field (MF) with induktion

of 100, 200, 250 and 300 Gs on growth and activity of a catalase and

peroxidase of a plant, and also the maintenance of photosynthetic pigments in

flax sprouts.

### EFFECT OF AMBIENT TEMPERATURE ON THE HUMIFICATION OF PLANT LITTER

#### Abstract

Techniques of laboratory microecosystems, small groups of arthropods and physical and chemical studies are shown. On the basis of instrumental studies the effect of temperature on the ratio of the processes of mineralization and humification of plant residues with the participation of small arthropods is computed. Analysis of the results of measurements of indicators of the process of

humification clearly reveals that the temperature of the plant material affects the intensity of humus accumulation and on indicators of the degree of maturity of humus acids. Activity of microarthropods reduces the dependence of accumulation of humus substances on the temperature.
