Abstract

The contribution of fungi and bacteria to the process of net ammonification in the soddy–podzolic soil of the wood sorrel–bilberry birch forest of Yaroslavl oblast has been determined using inhibitory analysis. Representatives of the genera Penicillium Link (70–99%) and Trichoderma Pers. (6–20%) dominate in the mycobiota of saprotrophic fungi. Seasonal changes in the total number of fungi and the content of C_org and N_org in the soil correlate only in the eluvial horizon, with r = (–0.8) and (–0.7). In horizons A₀ and A₂, total fungal abundance is negatively correlated with nitrogen accumulation, with r = (–0.85) to (–0.89). It has been established that the litter is characterized by an equal participation of fungi and bacteria in this process. In the humus horizon, a slight excess of the participation of fungi over bacteria is noted. In the eluvial part of the profile, the contribution of bacteria is slightly higher than the contribution of fungi. The maximum air temperature is able to regulate the seasonal dynamics of the number of saprotrophic fungi in the soil.

真菌和细菌在俄罗斯欧洲南部泰加桦树林土壤氮化合物矿化过程中的作用

摘要使用抑制分析法确定了真菌和细菌对雅罗斯拉夫尔州木香-山桑-白桦林草皮-块状土壤净氨化过程的贡献。青霉属（70%-99%）和毛霉菌属（6%-20%）在亚罗斯拉夫尔州的土壤中占主导地位。(6-20%）在嗜渍真菌的菌群中占主导地位。土壤中真菌总数和 Corg 与 Norg 含量的季节变化仅与冲积层相关，r = (-0.8) 和 (-0.7)。在 A0 和 A2 层，真菌总数与氮积累呈负相关，r = (-0.85) 到 (-0.89)。已经确定，在这一过程中，枯落物的特点是真菌和细菌平等参与。在腐殖质层中，真菌的参与略多于细菌。在剖面的冲积层部分，细菌的参与略高于真菌。最高气温能够调节土壤中食菌真菌数量的季节性变化。

期刊介绍： Contemporary Problems of Ecology is a multidisciplinary periodical that publishes original works on the following subjects: theoretical and methodical issues of ecology, regional aspects of ecology, regional ecological disasters, structure and functioning of ecosystems, anthropogenic transformation of ecosystems. All basic aspects of modern ecology, including the most complicated interactions between living organisms and their environment, are presented. Some of the journal issues are dedicated to global changes in biological diversity at various levels of organization (populations, species, ecosystems) principles and methods of nature conservation.
