Under-forest three-dimensional cultivation method for Dendrobium officinale

The invention discloses an under-forest three-dimensional cultivation method for Dendrobium officinale. The three-dimensional cultivation method for planting the Dendrobium officinale by means of forest tree bodies, tree segments, tree blocks, stumps and under-forest matrixes in an overgrowth mode has the advantages that the Dendrobium officinale is planted on original forest resources, no independent land sources are occupied, and therefore space is saved; completely-natural growth conditions are utilized, a large amount of manpower and a large number of material resources are saved, and therefore the planting cost is saved; the natural ecological environment is utilized, so that plant diseases and insect pests are effectively reduced without the need of applying fertilizer and pesticide; products obtained through the planting method are natural, free of pollution and high in quality; according to the planting method, the under-forest land resources are sufficiently utilized, the planted Dendrobium officinale has mobility due to the use of the tree segments, the stumps, the tree blocks and the like, the space utilization rate can be greatly improved, a large area of forest land resources can be reasonably utilized, and the method can be applied to other forestry gardens where imitated wild planting is not applicable and has wide application and popularization prospects.
