The invention relates to an interplanting method of
anoectochilus roxburghii and
polygonatum sibiricum under forests. The interplanting method comprises the following planting steps of selecting forests, performing
land parcel treatment, performing
land parcel soil improvement, selecting seedlings, performing planting, performing management after planting, and performing harvesting, wherein the step of selecting the seedlings comprises the steps of (1) soaking
rhizome segment cutouts of the
polygonatum sibiricum in a carbendazol bactericide solution prepared from diluting carbendazol bactericides with water of which the weight is 800-1500 times of that of the carbendazol bactericide, performing sealing with
plant ash, and airing the treated
polygonatum sibiricum
rhizome segments as seed stems; (2) thoroughly cleaning roots of the
anoectochilus roxburghii seedlings, performing disinfection with a 40-60%
iprodione wettable powder solution prepared by diluting
iprodione wettable powder with water of which the weight is 800-1500 times of that of the
iprodione wettable powder, and airing the treated
anoectochilus roxburghii seedlings as seedlings. According to the interplanting method of the
anoectochilus roxburghii and the
polygonatum sibiricum provided by the invention, the
polygonatum sibiricum can just provide shady environment for the
anoectochilus roxburghii, so that the landutilization rate can be increased, and soil, light and
water resources can be fully utilized; and soft rot and
stem rot of the
anoectochilus roxburghii at the early stage can be alleviated, the planting
survival rate of the anoectochilus roxburghii and the
polygonatum sibiricum can be increased, and the quality of medicinal materials can be guaranteed.
