The most typical example is the growth of fungi such as ascomycetes and green algae, or the growth of fungi and cyanobacteria. Among them, green algae or cyanobacteria carry out autotrophic photosynthesis to provide organic nutrition for fungi, and fungi carry out heterotrophic life, and decompose rocks with organic acids produced by them, thus providing mineral elements for algae or cyanobacteria.
Growth between rhizobia and plants. Including common rhizobia and leguminous plants, as well as other non-leguminous plants (Alnus cremastogyne, Myrica rubra, camellia, etc. ) and Frankenstein actinomycetes.
Mycorrhizal fungi and plants. Most plants in nature have mycorrhiza, which can improve plant nutrition, regulate plant metabolism and enhance plant disease resistance.
Some plants, such as orchids, are born with aseptic rhizosphere bacteria and will not germinate, and rhododendron seedlings are born with aseptic rhizosphere bacteria and cannot survive. Mycorrhiza can be divided into ectomycorrhiza and endomycorrhiza, and the latter can be divided into six main subtypes, but arbuscular mycorrhiza is the most important.
