A Detailed Guide to Poria (Wolfiporia cocos) Cultivation Techniques and Management Methods

Choose a slope facing east, south, or west with good drainage at 10-25°, with yellow sandy soil being best; when deep plowing, remove all debris thoroughly, and continuous cropping is not suitable; to cultivate Poria, use pine trees as the material, cut off some of their branches, leave the leaves at the tree top, then use a spade to peel off bark from 4-5 sides according to the size of the tree; Poria inoculation is divided into spring and autumn seasons, and it generally matures 8-10 months after inoculation.

Poria Cultivation Techniques

1. Site selection and land preparation: The Poria cultivation site should preferably be a slope facing east, south, or west with good drainage at 10-25°. Yellow sandy soil is best; clay soil and gravelly soil are not suitable for planting, and continuous cropping is not suitable either. After selecting the site, remove all debris thoroughly during deep plowing. In areas with termite damage, use termite-killing chemicals to disinfect the soil. Ten days before Poria inoculation, plow the land once more, break up the soil clods, and remove all debris thoroughly.

2. Material preparation: Poria mycelium growth depends on pine wood for nutrients, so pine trees must be used as the material for cultivating Poria. Choose pine trees with a diameter of 12cm or more that are not suitable for timber and cut them down (or use the tops and tails left after harvesting timber), cut off some of their branches, leave the leaves at the tree top, then use a spade to peel off bark from 4-5 sides according to the size of the tree (peeling down to the xylem is ideal). Between the peeled surfaces, leave 4-5 strips of bark about two fingers wide, and there should be no breaks from top to bottom. The remaining bark strips are called guide lines (commonly known as “liu jin” or “retaining veins”).

After 10-15 days, once the trunk has dried in the sun until cracks appear, saw it into small sections 70-80cm long, and stack them in a “well” pattern in a dry, sunny place. Cover the log stack with grass, dig drainage ditches around the stack, and scatter termite-killing chemicals on the ground.

3. Inoculation season: Poria inoculation is divided into spring and autumn seasons. Spring planting is carried out from Qingming to Lixia. In southern Guangxi, southeastern Guangxi, and western Guangxi, where temperatures rise earlier, inoculation around Qingming is more suitable; in northern Guangxi and northwestern Guangxi, inoculation around Lixia is preferable. In autumn, temperatures differ little across regions, so Poria can be inoculated around Liqiu.

4. Harvesting and processing: Poria generally matures 8-10 months after inoculation. Place the harvested Poria in a wind-protected indoor area, cover tightly with rice straw and let it “sweat” for 5-6 days, then spread it out to air for 1-2 days. After the moisture evaporates, pile it up again, cover tightly with rice straw for another 5-6 days, then remove the skin (or first peel off the fresh Poria outer skin), place it in a steamer and steam over water until thoroughly cooked through, or boil in water until thoroughly cooked through (change the water 3-4 times during boiling; the indicator is to change the water when it turns black). Take it out and use a sharp knife to cut it into blocks of length × width × thickness = 4cm × 4cm × 0.5cm.
