摘要
跟踪检测中科院红壤生态站三种不同土壤中微生物数量在一年中的变化 .结果表明 :不同利用方式下 ,土壤微生物数量和区系组成有较大差异 ,水田以细菌为主 ,占总菌群的 76 .83% ;旱地中真菌和放线菌的比例显著上升 ,分别占总菌群的 2 5 .6 8%和 2 2 .5 7% ;林地中真菌的比例在三种土壤类型中最高 ,达到 4 8.5 2 % .同时发现 。
The changes of microorganisms' number in different kind of Red Soil from CAS Ecological Experiment Station were detected. The results showed that the number and composition of microorganisms varied greatly with the type of soil. In the paddy field the bacteria were predominated, accounting for 76.83% of the total of bacteria, fungi and actinomyces; in the dry land the proportion of fungi and actinomyces was distinctly higher than the other two kinds of soil, accounting for 25 68% and 22.57% respectively; in the woodland the proportion of fungi was increased to 48.52% compared to the other two kinds of soil.
