Study on the Distributive Characteristics of the Soil Microorganisms at Floodplain on Wetland of Mongolian Plateau

Abstract:

Study on the distributive characteristics of the soil microorganisms at floodplain on wetland of Mongolian plateau. Using the Plate dilution method to determine the 0~10cm, 10~20cm, 20~30cm, 40~50cm and 50~60cm soil samples, soil aerobic bacteria, bacillus type bacteria, fungus and actinomycetes bacteria number, the results show that with the deepening of the soil depth, the number of aerobic bacteria number reduced, the peak value of the number of aerobic bacteria in the 0~10cm soil layer, the minimum number in the 50~60cm soil, 0~10cm and the other four soil there was a significant difference, there was no significant difference between the other four soil layers. The Bacillus type bacteria have a high ratio of total aerobic bacteria in 0~10cm, the surface of the soil with a high ammonification quality but also the best. The peak of the number of fungus in 0~10cm, followed by 10~20cm and 30~40cm and 20~30cm, 40~50cm, 50~60cm no isolated fungus. There is no actinomycetes separation in the 10-3 cfu.g-1dry soil dilution.
