The species composition of Fusarium genus is more rich and diverse in agrophytocenoses than in natural soils of vertical zones of the Chatkala mountain systems. Soils at the height of 600-700 m were the poorest in the number of Fusarium genus fungi while agrophytocenoses were the richest in the fungi. Certain differences in the species diversity and the number of Fusarium genus were found in the soil of the root zone of plants Poa bulbosa, Juniperus sarevschanica and Festuca valesiaca. The maximum of their development was observed in the alpine soils in summer and in autumn and in alpine soils in spring and in summer. The possibilities of plants affection increase in the period of biological activity of these fungi. Representatives of Fusarium genus are an important component of phyto and agrophytocenoses; they take active part in the processes of soil formation.
与恰特卡拉山系垂直地带的天然土壤相比，镰刀菌属的物种组成在农业植物群落中更为丰富多样。海拔600 - 700米处的土壤中镰刀菌属真菌数量最少，而农业植物群落中的此类真菌最为丰富。在鳞茎早熟禾、萨雷维希桧柏和瓦莱羊茅植物根区的土壤中，发现了镰刀菌属在物种多样性和数量上的某些差异。它们在夏季和秋季的高山土壤以及春季和夏季的高山土壤中发育最为旺盛。在这些真菌的生物活性期，植物受影响的可能性增加。镰刀菌属的代表是植物群落和农业植物群落的重要组成部分；它们积极参与土壤形成过程。
