NON-LINEAR MODELS AND EFFECTS OF THE COMPETITION OF PLANTS

Smagin A. V.

The problem of competing plants relationship is considered quantitatively. Non-linear power-law model of dependence of weight (gain) on the density of planting the plants obtained empirically and on the basis of its calculation formulas for the productivity (yield) of a plurality of types of plant communities are proposed. Two fundamentally different types of crop (b + and b–culture) with raising and lowering the overall produc-tivity in the transition from individual plants in their entirety to phytocenosis with increasing density were identified. The nonlinear dynamic model with trigger regime of competition under the influence of the edaphic factor controlling moisture are described.

ESTIMATION OF THE ONTOGENY STAGE DURATIONS FOR HERBA-CEOUS PLANTS, SPECIFICALLY ANTHYLLIS VULNERARIA L.

Kazantseva E. S., Medvedev V. G., Onipchenko V. G.

The new method of estimation of the ontogeny stages duration and plant lifespan was developed. The proposed method is based on a discrete ontogeny description and on the probability theory and random processes. Marked individuals from short-lived alpine plant species Anthyllis vulneraria were studied in the Northwest Caucasus in Russia on a height of 2800 m. We found out that the stage duration of young individuals (seedlings, juvenile and immature plants) of Anthyllis vulneraria is 0.8±0.09 years, adult veg-etative 1.1±0.2 years, generative 0.7±0.05 years. Lifespan is 2.6±0.3 years, with a life expectancy of – 1.9±0.4 years.

We have performed comprehensive studies of the fish community of the coastal sites in the Zaporozhian reservoir with different degree of anthropogenic load. It was found that the impact in the areas of technological and household wastewater being degraded degradation of structure of coastal fish community with substantial dominance of low-value species, as evidenced by a high index of cenotic significance, as well as reduce the morphological characteristics of fry fish compared to ecologically favorable areas. In areas with high anthropogenic load have been revealed to various adaptation mechanisms of erythropoiesis in fry fish of different ecological groups to the hypoxia.

BIOCHEMICAL COMPOSITION OF ROE AND JUVENILE FISH TISSUES UN-DER THE VARIOUS ANTHROPOGENIC EFFECTS UPON RESERVOIR

It had been found significant differences in the content of total protein and lipids in roe and tissues of juvenile commercial fish from two areas of Zaporozhian Reservoir (Ukraine) with varying degrees of pollution. In the biological samples collected at the contaminated area, the protein level was decreased significantly, whereas the contents of lipids were increased in comparison to the clean area. The results indicate a violation of protein-lipid ratio in the calf and biological tissues, when the deficit of plastic sub-stances was compensated by the energy ones.

Identification of the general size a biomass american artichoke on the irrigation fields of Gissar and Rasht valleys fluctuates within from 66.5 to 94.2 t/hec. and on rein field from 30.4 to 72.5 t/hec., yield of tubers from 24.95 to 38.4 t/hec. on the irrigation fields and from 11.85 to 22.95 t/hec. on rein fields. On the american artichoke average the biomass on the irrigation fields makes 78.8 t/hec. and on rein fields 47.4 t/hec, and a crop of tubers accordingly 30.63 and 15.73 t/hec. that testifies to efficiency of cultivation american artichoke in irrigation and rein fields of our republic. The irrigation promote increase of biomass yield of american artichoke on 30.4 t/hec. (64.1 %), yield of tubers on 14.9 t/hec.( 94.7 %) in comparison with cultivation without irrigation.

This article examines the types of technogenic impact on soils of agricultural lands. It was found that various construction and repair works may cause decreasing in nutrients content and humus, acidification and increase degree of soil density. Proposals for recultivation of such soils with types and doses of fertilizers were made.

This paper presents a study on aqueous-alkaline cleavage of malathion sorbed ON Armenian natural zeolite - clinoptilolite. The purpose of research, along with the disposal of sorpted malathion, was the restoration of the sorbent for future use. It is found that malathion destruction dependence on temperature of the experiments conditions. At high temperatures, the reaction proceeds according to the mechanisms of E-2 cleavage. The amount of formed organic products was controlled by the characteristics of the fractional composition, followed by GLC and HELQ. Definition derived substances investigated versatile and economical method of infrared (IR) spectroscopy and ultraviolet (UV) spectroscopy.

Shows a great variety of morphological and physico-chemical properties of sod-podzolic soil depending on the conditions of their formation. The effect of landscape features on soil formation in this region, we estimated the impact of different uses on the formation of specific soil properties. The main features af-fecting the specificity of formation of sod-podzolic soils of landscaped areas of the Volga-Oka interfluve are primarily soil-forming rocks, formed as a result of the different nature of the postglacial transfor-mation, and the different degree of anthropogenic load on soil сover.

Development of annual crops in the composition of cultural landscape with an active development of various communities of living organisms, based almost entirely on the replacement of natural plant communities artificial. The combined crops with a very wide range of their formation, meaning, and importance of the problems under consideration, including plants, living organisms and soil. Conventionally, the artificial combination of crops in the agricultural landscape we divide into three groups according to their importance: 1) a perennial hay and pasture, 2) to combine perennial and annual species (3-4 year crop) alternating with 4–5-year crops annual industrial crops (e.g., cotton), 3) seasonal annual crops with field crops.
