摘　　要：对辽宁省岫岩县6个五味子园的五味子根际土壤微生物数量、真菌多样性进行了初步研究,并对拮抗菌株进行了筛选。结果表明:5号样地土壤肥力、土壤微生物数量和真菌多样性指数均大于其他样地,6个土样中共分离到微生物168株,对五味子茎基腐病病原菌有拮抗性菌株11株,其中菌株1-1、3-1和3-2抑菌效果尤为明显,在不同程度上影响靶标菌菌丝生长,具有一定研究价值。真菌69株,经鉴定属于11个属,其中以镰刀菌属为优势属。Rhizosphere soil microorganism, microbial diversity and antagonism strains in six Schisandra chinensis gardens in Xiuyuan of Liaoning province were studied. The results showed that soil fertility, quantity of soil microorganism and diversity index of the 5th sample are more than others, 168 strains of microorganism are isolates from six samples, and 11 strains have antagonism to pathogen of Schisandra Stalk Rot Disease, in which strain 1 - 1, strain 3 - 1 and strain 3 - 2 have great potential for use as antagonistic microorganism to control the disease. To different extents, the strains impact target mycelial growth, which is of certain value for research.
