Description
Technical Field
The invention relates to the technical field of plant cultivation, in particular to a method for cultivating dendrobium candidum by ecologically returning rock walls.
Background
Dendrobium officinale is a precious Chinese herbal medicine material, and is a popular choice for the traditional Chinese medicine. However, the growth period is slow, the dendrobium candidum is extremely difficult to survive, and is mined by manpower in large quantities, and the wild dendrobium candidum is endangered and extinct. Therefore, artificial cultivation becomes a good measure for protecting endangered resources and meeting the needs of people. In order to obtain high-yield and high-quality dendrobium candidum, a superior growing environment must be created artificially, so that the planting condition is basically close to the wild environmental climate condition to meet the growing requirement, and the selection of the culture medium greatly affects the survival rate, growth, propagation and yield of the dendrobium candidum to be transplanted, so that the cultivation of the dendrobium candidum before the transplanting is crucial. Meanwhile, the roots are aerial roots, have obvious aerobic property and shallow root property, and the transplanted matrixes are loose and breathable, have good drainage, are not easy to mould, have no bacteria and are suitable for people with harmless insect potential.
In recent years, artificial propagation and planting of dendrobe have been successful, and large-area planting has been achieved. However, the existing various artificial planting methods mainly comprise greenhouse planting, tree planting, rock wall returning planting and the like. In various processes of greenhouse planting, tree planting and the like, the quality of dendrobe products on the market is low due to the application of fertilizers, pesticides and plant hormones, and the national standard cannot be met.

The dendrobium nobile has more trace elements, and natural fertilizer can be provided for the dendrobium nobile by utilizing the characteristics of the danxia landform, so that manual fertilization is not needed;
however, the method cannot ensure the survival rate of the dendrobium candidum, and has extremely high quality requirements on the dendrobium candidum under extreme conditions, so that the dendrobium candidum cannot grow on a large scale.
