| Abstract | A large prospect of developing of the ecologically safe agrotechnology of legumes cultivation without application of the mineral fertilizers and chemical preparations for plants/crop protection from phytopathogens in article is shown. Using poly–functional biological preparations including of heterotrophic and phototrophic microorganisms with the symbiotic, nitrogen-fixing, phosphate mobilizing, growth-promoting, antagonistic activities, is worthy alternative to the aggressive chemical treatment of soil and plants. Development of the elements of ecologically safe agricultural biotechnology, that can reduce of energetic and economic looses due to the crop pathogens and diseases, chemical fertilizer consumption, risk of the environmental pollution and destruction of the natural ecosystems, was the purpose of the research. The article is devoted to the three-year investigation of microbial processes in the soil rhizosphere and productivity of plants under the conditions of use bacterization of poly–functional microbial preparations in the cultivation of legumes in the steppe zone of Crimea. It is established that the orientation of these processes depend on the phase of development, species of the legumes plants, as well as from the introduction of poly–functional microbial inoculates. The possibility of intensification of microbiological processes in the rhizosphere of southern chernozem at different stages of ontogenesis soybeans, pea, peavine and lentil under the conditions of use poly–functional preparations on the basis of heterotrophic and autotrophic microorganisms it is shown. Revealed, that the synthesis of organic substances in the rhizosphere of soybean and pea was to the end of the growing season (ratio of mineralization = 0,4–0,8), the decomposition of organic matter in the rhizosphere of peavine and lentils was before the end of the growing season (ratio of mineralization > 1,0). It is revealed that the application of cyanobacterial consortium influenced on the index of oliogotrophic and contributed to the enrichment of the rhizosphere on organic substance. Activation of microbiological transformation of organic substance in the rhizosphere soil was in the phase of the blossom and bobs breeding of soybeans, to the end of the pea vegetation, at the beginning of vegetation and in bobs breeding phases of the peavine and lentil. The intensity of this process was different in variants with bacterization. Treatment of poly–functional microbial preparations improved the seed yield of legumes by 0,14–0,80 t/ha (14,7–56,3%) and crude protein yield of 2,5–4,8% compared with bacterization of Rhizobofit. Study in 2014 was financially supported by RFFI and the Republic of Crimea within the framework of scientific project 14–44–01621 «r_ug_a». | ||
