The invention discloses a method for treating continuous cropping soil of panax pseudo-ginseng by using a soil fumigant dazomet. The method comprises the following steps of: (1) soil preparation, (2)fumigation pretreatment, (3) film covering for fumigation and (4) film removing for ventilation. The method has the advantages that: the seedling survival rate of seed twigs of panax pseudo-ginseng inthe continuous cropping soil can be improved effectively, and meanwhile the growth trend of plants of panax pseudo-ginseng can be enhanced effectively; and the continuous cropping soil can be supplemented with trace elements through pretreatment of the continuous cropping soil, so that the seedling survival rate of the seed twigs of panax pseudo-ginseng in the soil is improved.
