The actinomycetes complexes in the rhizosphere of three agricultural plants by using the methods of luminescense microscopy and cup sowing were investigated. It was established, that concentration of prokaryotic biomass and biomass of actinomycetes mycelium in rhizosphere of plants is higher than in free from the radicals to soil. Rhizosphera of the oat (Avena sativa L.) and red clover (Trifolium pratense L.) is colonized by Streptomyces, Micromonospora and olygospore species. Dominante actinomycetes of winter rye (Secale cereale L.) are classified into the genera Micromonospora. It was shown that numbers and biomass of actinomycetes mycelium were fond to decreased, diversity of actinomycetes in contrast is increased in the series: "winter rye--oat--red clover". In connection with ecological safety the capability of increase with prokaryotes naturally disease suppressive soil and stability of plants to pathogen is discussed.
采用发光显微镜和杯播法对三种农作物根际的放线菌复合体进行了研究。结果表明，植物根际原核生物生物量和放线菌菌丝体生物量的浓度高于远离根系的土壤中的浓度。燕麦（Avena sativa L.）和红三叶草（Trifolium pratense L.）的根际被链霉菌属、小单孢菌属和寡孢菌种定殖。冬黑麦（Secale cereale L.）的优势放线菌被归类为小单孢菌属。结果表明，放线菌菌丝体的数量和生物量呈下降趋势，相比之下，放线菌的多样性在“冬黑麦——燕麦——红三叶草”序列中增加。结合生态安全性，讨论了原核生物自然抑制病害土壤的增加能力以及植物对病原体的稳定性。
