Basic knowledge of orchid mycorrhiza

Orchid mycorrhiza does not absorb carbohydrates through host cells, but takes carbon sources from other living or dead residual organic matter. The mycorrhiza of Orchidaceae only has loose exophytic hyphae on the root surface connected with other plant roots or dead organic matter in the soil, and can decompose more complex carbohydrates in soil or withered branches and leaves into simple small molecular carbohydrates and transport them to the host. The infection of orchid root fungi improved some metabolic defects and deficiencies in orchid plants, stimulated a series of metabolic processes, guided the migration of nutrients, and thus promoted the growth of orchid plants.

1. During the period of weak photosynthesis, it is important for mycorrhiza to provide nutrition.

2. The roots of other living plants in the orchid basin can also be used by mycorrhizae to absorb carbon sources.

3. Mycorrhiza needs a breathable environment.
