摘　　要：[目的]以8年生荷木林下土壤微生物为研究对象,探讨乡土树种荷木土壤微生物不同季节上的变化。[结果]荷木在土壤微生物总数量、总生物活性、共生功能固氮菌总量上占据优势。[结论]以土壤微生物的角度分析,可采用速生荷木代替现有南方速生树种进行人工林的生产、经营。[Objective]The soil microorganisms under 8-years-old lotus plantations were taken as the research object to investigate the seasonal changes of soil microorganisms in native lotus species.[Result]The total number of soil microorganisms,the total biological activity and the total amount of symbiotic nitrogen fixing bacteria were dominant.[Conclusion]From the perspective of soil microorganism,it is feasible to replace the existing fast-growing species of Southern China with fast-growing lotus for plantation production and management.
