The invention discloses a high-yield anoectochilus roxburghii planting method. The method includes the steps that a greenhouse is erected; a plurality of supporting frames are arranged in the greenhouse, and seedling culture plates are placed on the supporting frames; the bottoms of the multiple supporting frames are provided with a drainage ditch, then a plurality of spray irrigation devices are mounted, and one seedling culture plate corresponds to one spray irrigation device; planting base materials are laid in the seedling culture plates, anoectochilus roxburghii seedlings are planted in the planting base materials after being sterilized, water is sprayed to the planting base materials through the spray irrigation devices, and the planting base materials are drenched thoroughly. The spray irrigation devices are arranged, a great amount of manpower can be saved in a later period, a filtering device is arranged, redundant water in the planting base materials can be filtered and then discharged through the drainage ditch, the base materials can reach proper humidity, water accumulation cannot occur easily, the survival rate of anoectochilus roxburghii can be raised, and thus the yield of the anoectochilus roxburghii can be raised.
