摘要： 采用田间随机区组试验，选择前茬种过西洋参的老参地，用大扫灭、二硫化碳、多菌灵等3种低毒化学农药和紫苏根作为添加物进行土壤处理，处理后播种西洋参，调查出苗、存苗、根的生长及根病情况。探讨化学农药及植物添加物处理老参地土壤对改善重茬西洋参生长及减少病害的作用。试验结果表明，98%大扫灭粉剂5g/m2~15g/m2、二硫化碳液剂20ml/ m2进行土壤熏蒸处理，对提高重茬西洋参的出苗率、保苗率、产量，以及减轻根部病害均有较好的效果；添加紫苏根50g/m2~100g/m2的作用主要表现为可以提高根重，多菌灵消毒的作用效果不明显。

Abstract: The aim of this paper was to compare the effect of different pesticides and plant amendments treated replant soil on the growth and root rot of Panax quinquefolium L. Field plot trail of continuous cultivated P. quinquefolium L was conducted by using Dazomet, CS2 and Perilla frutescens root meal treated soil. The rate of seedling emergence and survival ，incidence of rot root and root weight of Panax quinquefolium were investigated in first and second year. The results showed Fumigating soil with 5~15g/m2 Dazomet, 20mL/m2 CS2 improved the percentageof establishment and survival of seedling, increased weight of root and reduced root disease of continuous cropping Panax quinquefolium L. Adding 50g/m2~100g/m2 Perilla frutescens root meal in soil could increase weight of root.But the carbendazim had no effect in compare with control. So fumigating soil or adding suitable botanical amendments in soil are beneficial to solving the replant problem of Panax quinquefolium L.
