To study the effect of different organic amendments treated replant soil and to find the relations between the soil fungi community and the growth of Panax quinquefolium L. seedling.
The soil was treated with bone meal and Perilla frutescens root meal, the rate of seedling emergence, incidence of rot root and root weight were investigated. The fungi community and the pathogen, Fusarium solani and Phytophthora cactorum population were counted by soil dilution plating technique.
The organic amendments especially Perilla frutescens root meal treated soil could reduce the population of Fusarium solani and Phytophthora cactorum in soil, thus lessen the root disease of continuous cropping Panax quinquefolium and increase survival of weedling.
Adding suitable organic amendments in soil can change the soil fungi community and be beneficial to solving the replant problem of Panax quinquefolium.
研究不同有机改良剂处理重茬土壤的效果，探寻土壤真菌群落与西洋参幼苗生长之间的关系。
用骨粉和紫苏根粉处理土壤，调查出苗率、烂根发病率和根重。采用土壤稀释平板法计数真菌群落以及病原菌茄腐镰刀菌和恶疫霉的数量。
有机改良剂尤其是紫苏根粉处理的土壤可减少土壤中茄腐镰刀菌和恶疫霉的数量，从而减轻连作西洋参的根病，提高幼苗成活率。
在土壤中添加适宜的有机改良剂可改变土壤真菌群落，有利于解决西洋参重茬问题。
