The invention discloses a wild-imitating cultivation method for dendrobium officinale. The method includes the steps of planting field selecting, before-planting preparing, planting, seedling management and final-period management. A Reno mattress filled with rocks and / or gravels is laid on a forest land, a stone basal plane with a uniform height is convenient to construct and lay through the Renomattress, the stones can be also prevented from loss, the service life is long, then mosses are sown on the stones, and then dendrobium officinale domesticated seedlings are planted in stone seams. In this way, the dendrobium officinale seedlings have a growth environment similar to that of wild dendrobium officinale, and it is kept to grow naturally in original ecology for the dendrobium officinale seedlings, mineral absorption during growth is guaranteed, and since the mosses have good moisture preservation, the air humidity of a local environment can be effectively kept, and the growth ofdendrobium officinale can be promoted. The survival rate of the dendrobium officinale seedlings is effectively increased, the medicinal value of dendrobium officinale is effectively increased, benefits are high, the planting method is easy to operate, and dendrobium officinale is easy to plant and harvest.
