| 1 | The influence of the light correcting films of various compositions on vital activity of sprouts of cabbage was researched. For this purpose the technique of comparative trials was completed. The technique consists in cultivation of sprouts of cabbage in hothouses by a size 1x1x0,6 m, covered by different films with a control of plant's metrics. Is shown, that usage of films with various physical properties renders considerable influence on metrics index under them of cabbage's sprouts. The composition of the light correcting Alms permitting of cabbage's sprouts in a closed ground in locale of Western Siberia without padding heating and lighting and to reduce period of cultivation on 10-15 of days is defined. | 1559 | ||||
| 2 | The research of features of fluorescence of dispersed photosphors in conducted on the basis of organic and inorganic connections of a europium and polymer films with their components at excitation of solar radiation. The excitation of luminescence of phosphors by UV radiation of the sun does not change spectral content of luminescence radiation. For number of photophosphors on the basis of ocsysulfide of yttrium, activated with europium watches change of intensity of minor bands in luminescent spectrum concerning the principal band, that it is necessary to allow for consideration of photophysical characteristics of corrective light films with their components. The obtained data allow to conduct calculation of intensity of luminescence radiation under corrective light films with allowance for its spectral content | 1688 | ||||
| 3 | The work makes analysis of the regularities of sharing of the separate groups of microorganisms in oligotrophic mires of West Siberia with using cluster-analytical method. The relationships between characteristic, regimes of oligotrophic mires and activity of the biochemical processes are revealed. Keywords: peat mire, peat formation, biochemical processes, microflora, cluster analysis | 1689 | ||||
| 4 | The article studied the influence of luminiscent radiation of photoluminescent films on augmentation of productivity of plants in a greenhouses, and also the reflected, absorbed and dissipated solar light photoluminophore particles in films. It is experimentally erected, that the basic contribution to augmentation of productivity of plants to a greenhouses under photoluminescent films imports the luminescent radiance generated by films. Productivity also is spotted by a relation getting on a plant direct and a diffused light. Keywords: a greenhouse, a solar light, a photoluminescent film, luminescent radiation, productivity | 1522 | ||||
| 5 | Productivity of Lactuca sativa, variety Moskovsky parnikovy growing in protected cultivation under fluorescent film luminescent with maximum of 615 nanometers is studied in dynamics. Change of conditions of plant cultivation by fluorescent film promotes accelerated growth, development and productivity improvement of Lactuca sativa relative to plants growing under unmodified film. Increase in productivity of Lactuca sativa in 1.5 times under fluorescent films is determined by increase in ratio IAA/ABA and decrease in content of АA in plants, and also conjugated with change of enzymatic activity of aboriginal soil microflora. Keywords: Lactuca sativa, protected cultivation, fluorescent films, productivity, hormones, ascorbic acid, soil microflora | 1611 | ||||
| 6 | The fluorescen properties of polyethylene photoluminescent films connected with injecting to their composition of photoluminophor on the basis of linkings of europium in excitation of UV by radiation of the sun are investigated. For the first time experimental measurement of rates of fluorescent radiation of a photoluminescent film at its exploitation in natural conditions are carried out. The maximum values of fluorescence intensity of films in investigated conditions make near to 8 mW/m2, average day from 0.5 to 2 mW/m2. For the first time the received results have allowed to make a quantitative estimation of fluorescent radiation intensity of photoluminescent films at effective cultivation under them plants in natural conditions. Reproducing of such indices can allow transferring effect studying to controllable laboratory conditions. Keywords: the polymeric, fluorescent, agricultural films; optical properties | 1434 | ||||
| 7 | Productivity of Lactuca sativa L. Lolla Rossa in the conditions of protected cultivation under fluorescent polyethylene film and polyethylene terephthalate films (lavsan) was studied in the article. The change in the conditions of plants, growing with the use of modified polymer films, contributes to accelerated growth, development and productivity of L. sativa in relation to plants grown under unmodified polyethylene film. Increase of L. sativa productivity was attended with growth of ascorbic acid (AA) level and change in catalase activity in plant leaves. Keywords: unmodified polyethylene film, fluorescent film, lavsan, Lactuca sativa L., productivity, ascorbic acid, catalase | 1460 | ||||
| 8 | The deals with the questions of the mutual influence of the nature the polymeric matrix and the type phosphor on luminescence properties of their compositions with homogeneous distribution of the phosphor. It presents data on the photochemical stability of two types phosphors in the polymers (polystyrene, polymethylmethacrylate), the intensity of luminescence. Keywords: luminescence, the polymer matrix, photochemical stability, organic phosphor, optical properties | 1326 | ||||
| 9 | The use of photoselective polyethylene films with thermic properties used as greenhouse cover materials at cultivation of Eruca sativa Mill., Korsika resulted in change of vegetative growth and plants development. The thermic films have IR-reflecting properties (700–1400 nm) due to low-emission coatings with copper compounds (film TF1) and compounds of silver and copper (film TF2) on the surface of polyethylene films. The use of thermic films was conducive to decrease in wide fluctuations in day and night temperatures in greenhouses, because of increase in night temperatures up to 2 °C compared to unmodified polyethylene film. The change of light and temperature growth conditions of E. sativa by thermic film (TF-2) resulted in increase the yield (leaf number, fresh weight, and dry weight). Increase in productivity up to 60 % was followed by the rise in ascorbic acid level in plant leaves. Thermic film TF-1 did not contribute to change of plant growth, development and productivity of Eruca sativa compared to unmodified polyethylene film.
