Structural organization of microbial populations in soddy-podzolic soil was studied during growth of agricultural plants in monoculture and in crop rotation. The content of bacteria and their biomass decreased when plants were grown in monoculture. The content of actinomycetes, bacilli and oligonitrophilic microorganisms increased in soil during crop rotation as compared with monocultures, suggesting a higher rate of mobilization processes. The content of microscopic fingi in soil increased when lupine was grown in monoculture. Growth of plants in monoculture affects the cenotic structure of soil microflora. The composition of active soil microflora was characterized by a wider spectrum of microbial forms during crop rotation of monocultures.
在单作和轮作的农业植物生长期间，对灰化土中微生物种群的结构组织进行了研究。当植物单作生长时，细菌含量及其生物量会下降。与单作相比，轮作期间土壤中放线菌、芽孢杆菌和寡养嗜氮微生物的含量增加，这表明有更高的活化过程速率。当羽扇豆单作生长时，土壤中微观真菌的含量会增加。植物单作生长会影响土壤微生物区系的群落结构。在单作轮作期间，活性土壤微生物区系的组成具有更广泛的微生物形态谱特征。
