Flora of soil microorganism in the different grassland types in the Linzhi region

The diluting plate method was used to isolate the soil bacteria, fungi and actinomycetes of alpine meadow grassland, marsh grassland and cultivation pasture in the Linzhi area. The results of this study showed that the bacteria was dominant microorganisms and accounted for 91.2%, and actinomycetes only accounted for 3.79% for each grassland type. The total microbes number was cultivation pasturemarsh grasslandalpine meadow. The amount of microorganisms at 0-10 cm soil layer was significantly greater than that at 10-20 cm soil layer. Soil moisture content in the different grassland types are very different, and low humidity conditions are advantageous to the growth of actinomycetes, but disadvantageous to fungi growth.
