A Detailed Guide to the Basics of Orchid Mycorrhizae: A Must-Read for Beginners in Orchid Growing

Orchid mycorrhizae do not absorb carbohydrates through host cells; instead, they take up carbon sources from other living or dead residual organic matter. The mycorrhizae of orchids have only loose ectomycorrhizal hyphae on the root surface, connecting with the root systems of other plants in the soil or with dead organic matter. They can decompose the more complex carbohydrates in the soil or in fallen leaves and rotten branches into simple small-molecule carbohydrates and deliver them to the host. At the same time, after infection by orchid root fungi, certain metabolic defects and deficiencies in the orchid plant are improved, a series of metabolic processes is activated, and the migration of nutrients is guided, thereby promoting the growth of the orchid plant.

1. During periods of weak photosynthesis, it is very important for the mycorrhizae to provide nutrients.

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

3. Mycorrhizae need an air-permeable environment.
