The impact of the Common Osier (Salix viminalis L.) root system on number (CFU) of heterotrophic bacteria and their production in a soil-willow filter was examined. The Osier rhizosphere was found to be suitable habitat for growth of the examined microbial group, and the root system stimulated development of heterotrophic bacteria. The rhizosphere bacteria to control soil bacteria (R:C) ratio oscillated between 2.48 and 2.75 depending on the location of sample collection. The highest abundance of bacteria as well as highest bacterial production was observed at location I, near sewage discharge onto the plot. There was a significant positive correlation between the number of heterotrophic bacteria and the bacterial production.
研究了杞柳（Salix viminalis L.）根系对土壤-柳树滤床中异养细菌数量（CFU）及其产量的影响。发现杞柳根际是所研究微生物群体生长的适宜生境，根系刺激了异养细菌的生长。根际细菌与对照土壤细菌的比例（R:C）根据样品采集位置在2.48至2.75之间波动。在靠近污水排放到试验区的位置I观察到最高的细菌丰度和最高的细菌产量。异养细菌数量与细菌产量之间存在显著正相关。
