The invention discloses a poria cocos cultivation technology which includes the first step of land preparation, the second step of material preparation, the third step of strain selection, the fourth step of inoculation, the fifth step of field management and the sixth step of harvesting and processing. In the step of land preparation, slightly acid soil good in drainage, loose and ventilated is selected. In the step of material preparation, good-for-nothing pine trees with the diameter larger than 12 cm are cut down, branches and bark are removed, and the pine trees are sawn into small segments and dried. In the step of strain selection, a proper number of culture media are added into the small pine tree segments, and mycelia are obtained. In the step of inoculation, the segmented wood is placed, small openings are cut, and the mycelia are placed into the small openings. In the step of field management, strain conditions are detected, and supplement is carried out in time. In the step of harvesting and processing, harvested poria cocos are placed in indoor lees, peeled, cooked and dried. By selecting planting land soil and adjusting the pH value of the soil, good conditions are provided for poria cocos growth. By means of the reasonable management technology, high quality and high yield of poria cocos are guaranteed.
